Documentation

Overview

Package generator implements the code generation engine that powers project scaffolding, command generation, and regeneration from manifest definitions.

The core Generator type orchestrates a shared pipeline: asset generation, command registration, child re-registration, manifest updates, and documentation output. It operates on a manifest-first architecture where .gtb/manifest.yaml is the single source of truth for project structure.

Key entry points are Generator.GenerateSkeleton for new projects, [Generator.GenerateCommand] for adding commands, and Generator.RegenerateProject for rebuilding registration files from an existing manifest.

Constants

)
View Source
const (
	// DefaultCICDComponentSource is the default include base for the
	// phpboyscout/cicd components. It is overridable via the manifest
	// `ci.component_source` value (O1) so a mirrored/self-hosted downstream
	// can repoint the include base; the default works out-of-the-box.
	DefaultCICDComponentSource = "gitlab.com/phpboyscout/cicd"

	// CICDComponentVersion is the phpboyscout/cicd component version the
	// scaffold pins (go-lint, go-test, go-security, goreleaser,
	// zensical-pages, releaser-pleaser). Mirrors the framework's own pin; kept
	// current automatically by the Renovate customManager in renovate.json5
	// (do not hand-bump — let Renovate propose it).
	CICDComponentVersion = "v0.35.0"
)

CICD component pins for the scaffolded GitLab pipeline.

These are kept in LOCKSTEP with the framework's own root .gitlab-ci.yml (resolved O2 of the 2026-06-15 generator-gitlab-ci-refresh spec): when the framework upgrades its phpboyscout/cicd component pins, bump these in the same change. The scaffolded renovate config (extending the cicd preset) then keeps the pins current for the downstream tool.

releaser-pleaser used to be pinned separately here, because the scaffold included apricote/releaser-pleaser/run direct and $CI_SERVER_FQDN-relative (instance-local) per O7. The scaffold now uses the phpboyscout/cicd wrapper instead — it carries the releaser-pleaser:verify tag guard — so it rides this same pin like every other component.

	DocsLayoutDiataxis = "diataxis"
	// DocsLayoutFlat is the legacy flat tree (docs/commands + docs/packages).
	DocsLayoutFlat = "flat"
)

Documentation tree layouts recorded in ManifestProperties.DocsLayout.

const KeychainFeature = "keychain"

KeychainFeature is the one `--features` value with no FeatureID behind it: it selects the scaffolded cmd/<name>/keychain.go blank import rather than a SetFeatures toggle, which is why it is absent from the catalogue and from ToggleableFeatures.

Variables

var BreakingChanges = map[string]string{
	"v2.10.0": "Breaking changes to Assets interface and command signatures. Please refer to the migration guide.",
}

BreakingChanges is a map of version strings to descriptions of breaking changes introduced in that version. The keys should be valid semantic version strings (e.g., "v2.10.0"). The values are messages displayed to the user when they upgrade across these versions.

View Source
var DefaultSelectedFeatures = defaultSelectedFromCatalogue()

DefaultSelectedFeatures is what `gtb generate project` selects when --features is omitted: every catalogue feature that is default-enabled in the framework, plus keychain. It is derived rather than written out so a change to a framework default cannot leave the generator's default set stale — and so the flag default and resolveFeatures cannot disagree about what "default" means.

Forge features are Default:false, so they are correctly absent: a scaffolded tool opts into a forge explicitly.

View Source
var ErrCommandProtected = errors.NewSentinel("gtb.generator.command_protected", "command is protected")
View Source
var ErrInvalidInput = errors.NewSentinel("gtb.generator.invalid_input", "invalid generator input")

ErrInvalidInput is the sentinel wrapped by every Validate* failure. Discriminate with errors.Is in callers that need to distinguish validation failures from other error shapes.

View Source
var ErrInvalidPackageName = errors.NewSentinel("gtb.generator.invalid_package_name", "invalid package name")
View Source
var ErrNoFrontmatter = errors.NewSentinel("gtb.generator.no_frontmatter", "AI documentation response contained no frontmatter")

ErrNoFrontmatter signals that an AI documentation response contained no YAML frontmatter fence at all, even after stripping any conversational preamble. The generator treats this as a generation failure and falls back to deterministic boilerplate rather than committing a frontmatter-less page.

SelectableFeatures is the set `gtb generate project --features` accepts — every toggleable feature plus keychain. It is deliberately wider than ToggleableFeatures: at generation time keychain is a real choice, whereas `gtb enable`/`gtb disable` cannot flip it in an existing project.

View Source
var ToggleableFeatures = featureNamesFromCatalogue()

ToggleableFeatures is the set of built-in features that `gtb enable <feature>` and `gtb disable <feature>` can flip in a generated project's manifest. It is derived from templates.FeatureCatalogue — the single source of truth — so it stays complete as features are added.

keychain is intentionally excluded: it is a build-time blank-import decision (the scaffolded cmd/<name>/keychain.go), not a FeatureID, so it is changed by adding/removing that file, not by a SetFeatures toggle.

Functions

func AppendIgnorePattern added in v0.34.0

func AppendIgnorePattern(fs afero.Fs, projectPath, pattern string) (changed bool, err error)

AppendIgnorePattern appends a single pattern to a project's .gtb/ignore, creating the file (with an explanatory header) when it is absent. It is idempotent: re-adding a pattern already present as a rule line leaves the file byte-identical and reports changed=false. Existing comments, blank lines, and ordering are preserved — the pattern is appended after them.

func EncodeManifestFile added in v0.17.0

func EncodeManifestFile(fs afero.Fs, manifestPath string, m *Manifest) error

EncodeManifestFile serialises m to the given manifest.yaml path on fs at the canonical two-space indent and writes it with DefaultFileMode. It is the single serialise-and-write helper for every manifest write site (scaffold, generate command, regenerate, add-flag, scan), so the render+write boilerplate — and the on-disk byte layout — cannot drift between sites.

func ManifestPathFor added in v0.17.0

func ManifestPathFor(projectPath string) string

ManifestPathFor returns the canonical .gtb/manifest.yaml path under the given project root.

func PascalCase

func PascalCase(s string) string

func PreviewAppendIgnorePatterns added in v0.34.0

func PreviewAppendIgnorePatterns(fs afero.Fs, projectPath string, patterns []string) (content string, err error)

PreviewAppendIgnorePatterns returns what .gtb/ignore would contain after appending patterns in sequence, composing them in memory without writing anything. It backs `--dry-run` on `gtb ignore add` with multiple patterns.

func PreviewRemoveIgnorePattern added in v0.34.0

func PreviewRemoveIgnorePattern(fs afero.Fs, projectPath, pattern string) (content string, changed bool, err error)

PreviewRemoveIgnorePattern returns what .gtb/ignore would contain after removing pattern, without writing anything. It backs `--dry-run` on `gtb ignore remove`.

func RemoveIgnorePattern added in v0.34.0

func RemoveIgnorePattern(fs afero.Fs, projectPath, pattern string) (changed bool, err error)

RemoveIgnorePattern drops the exact literal rule line matching pattern from a project's .gtb/ignore, preserving every other line (comments, blanks, and ordering). Matching is on the literal rule line, not on a path the pattern happens to glob, so `remove justfile` never touches an overlapping `*.yml`. It reports changed=false when no such line exists.

func ScaffoldIgnoreFile added in v0.34.0

func ScaffoldIgnoreFile(fs afero.Fs, projectPath string) error

ScaffoldIgnoreFile writes a fresh, comment-only .gtb/ignore (the header and nothing else) into a project, creating the .gtb directory as needed. It is a no-op when the file already exists, so it never clobbers a user's rules. A comment-only file ignores nothing, so scaffolding it is behaviourally inert — its whole value is discoverability.

func SealIgnorePattern added in v0.37.0

func SealIgnorePattern(fs afero.Fs, projectPath, pattern string) (changed bool, err error)

SealIgnorePattern appends a sealed rule for pattern — "<pattern> sealed" — which forbids every generator write to the path, wiring included (spec 0188 D3). Sealing implies ignoring, so one line is enough. Idempotent and comment-preserving, like AppendIgnorePattern.

func UnsealIgnorePattern added in v0.37.0

func UnsealIgnorePattern(fs afero.Fs, projectPath, pattern string) (changed bool, err error)

UnsealIgnorePattern rewrites a sealed rule back to a bare one, so the path stays *ignored* rather than becoming fully managed again. Dropping the line outright would silently hand the file back to the generator, which is unlikely to be what someone unsealing wants (D8).

It reports changed=false when no sealed rule for pattern exists.

func ValidateCIComponentSource added in v0.18.0

func ValidateCIComponentSource(source string) error

ValidateCIComponentSource accepts an empty string (meaning "use the framework default") and otherwise requires a bare host/path component source such as `gitlab.com/phpboyscout/cicd`. The value is interpolated verbatim into an unquoted YAML include path in the scaffolded .gitlab-ci.yml, so it is restricted to a strict character class (alphanumerics, `.`, `-`, `_`, `/`) and rejected if it carries a URL scheme, whitespace, control characters, or template delimiters.

func ValidateCommandName added in v0.17.0

func ValidateCommandName(name string) error

ValidateCommandName enforces the naming rule for generated commands — kebab-case plus underscore, a lowercase letter first, at most 64 characters: ^[a-z][a-z0-9_-]{0,63}$. Path separators and dots are rejected explicitly (before the character-class check) because the name flows into filepath.Join(path, "pkg", "cmd", name) and FS.RemoveAll — this rule is the gate that forecloses path traversal from CLI flags and tampered manifests alike.

func ValidateConfigLayers added in v0.36.0

func ValidateConfigLayers(layers []string) error

ValidateConfigLayers rejects any layer name the framework does not know, and any duplicate.

An unknown name would otherwise reach the emitter and render a props constant that does not exist, failing the generated project's build with an error pointing at generated source rather than at the manifest that caused it.

func ValidateDescription

func ValidateDescription(desc string) error

ValidateDescription enforces a bounded-length, control-character-free description that is safe to interpolate into YAML/TOML string values and Markdown prose. The rule explicitly forbids `{{` / `}}` as a belt-and-braces guard: text/template does not re-parse interpolated data, so this is not exploitable today, but matching the pattern lets a future change (e.g. switching to html/template with its `{{`-as-action reparsing) remain safe.

func ValidateEnvPrefix

func ValidateEnvPrefix(prefix string) error

ValidateEnvPrefix accepts an empty string (meaning "no prefix") and otherwise requires an upper-snake-case prefix matching `^[A-Z][A-Z0-9_]{0,31}$`. Shell metacharacters are excluded by the class; length is bounded so the rendered env-var name stays below POSIX limits.

func ValidateExternalCommand added in v0.34.0

func ValidateExternalCommand(ec *ManifestExternalCommand) error

ValidateExternalCommand validates a single manifest external_commands entry: the module path, the required version pin, the optional import path and alias, and every attach descriptor. It is the gate that forecloses a tampered manifest driving a go.mod require or a rendered constructor call outside the rules.

func ValidateFeatureName added in v0.18.0

func ValidateFeatureName(name string) error

ValidateFeatureName rejects any name that is not one of the toggleable built-in features (see ToggleableFeatures). Used by `gtb enable <feature>` / `gtb disable <feature>` so an unknown name fails fast with the valid set listed, rather than silently writing a junk manifest entry.

func ValidateFlagDefaultCode added in v0.33.0

func ValidateFlagDefaultCode(def string) error

ValidateFlagDefaultCode gates a flag default that renders as Go source (`default_is_code: true` emits the value verbatim via jen.Id). Only a bare identifier or a dot-joined selector (`defaultTimeout`, `time.Second`) is accepted — the shapes jen.Id is legitimately used for. Calls, operators, literals, and anything statement-like are rejected so a tampered manifest cannot compile arbitrary Go into a regenerated tool. Empty means "zero value" and is accepted.

func ValidateFlagName added in v0.17.0

func ValidateFlagName(name string) error

ValidateFlagName enforces the naming rule for a generated command's flag: kebab-case, a lowercase letter first, at most 64 characters (^[a-z][a-z0-9-]{0,63}$). The name becomes a Go identifier in the generated options struct and a cobra flag registration, so the same constraint as command names applies.

func ValidateFlagShorthand added in v0.19.0

func ValidateFlagShorthand(shorthand string) error

ValidateFlagShorthand accepts an empty string (meaning "no shorthand") and otherwise requires exactly one ASCII letter, which becomes cobra's single-rune shorthand (the `-x` form). Anything longer or non-letter is rejected before it reaches the StringVarP registration in the generated code.

func ValidateFlagType added in v0.17.0

func ValidateFlagType(flagType string) error

ValidateFlagType rejects a flag type the command generator can't render. The empty string and "string" are accepted (both map to a string flag); every other value must be one the generator's flagFuncMap knows. Without this gate an unknown type silently degrades to a string flag in the generated code.

func ValidateHost

func ValidateHost(host string) error

ValidateHost enforces an RFC 1123 hostname (optionally with `:port`). Punycode labels (`xn--...`) are accepted; raw Unicode labels are rejected — callers that need an internationalised host must supply the punycode form explicitly so homoglyph attacks fail visibly at input time rather than in a rendered URL.

func ValidateLongDescription added in v0.33.0

func ValidateLongDescription(desc string) error

ValidateLongDescription enforces a bounded-length, control-character-free long description. Unlike ValidateDescription, newlines are permitted — multi-line long descriptions are legitimate — and `|` need not be banned because the Markdown table sink escapes it (escapeMarkdownTableCell).

func ValidateManifest

func ValidateManifest(m *Manifest) error

ValidateManifest runs every user-influenced field of a loaded Manifest through the validators above. Used by regenerate and manifest-update paths so a tampered manifest fails fast before driving file writes.

Only [Manifest.Properties.Name] is unconditionally required — a manifest missing the tool name is structurally broken. Other fields are optional in the YAML schema and are validated only when populated; empty fields short-circuit to nil, matching the forgiving behaviour of the fine-grained validators above.

func ValidateName

func ValidateName(name string) error

ValidateName enforces the naming rule for the scaffolded tool — lowercase alphanumeric with optional hyphens, a letter first, and at most 64 characters. This tight rule simultaneously forecloses path traversal, Unicode spoofing, and YAML/TOML/Markdown/shell injection because none of the dangerous characters are in the class.

func ValidateOrg

func ValidateOrg(org, releaseProvider string) error

ValidateOrg enforces GitHub-org syntax for the `github` release provider and GitLab-namespace syntax for `gitlab`, including `/`-separated subgroups up to a reasonable depth. CODEOWNERS silently drops invalid `@`-mentions, so catching bad input early prevents the scaffolded project from shipping broken ownership rules.

func ValidatePackagePath added in v0.24.0

func ValidatePackagePath(pkgPath string) error

ValidatePackagePath validates the `--package` argument to `generate docs`: it must be a clean, `/`-separated path relative to the project root, with no absolute prefix and no `..` traversal. This forecloses writing the generated doc outside docs/ (the value flows verbatim into filepath.Join for both the source dir and the output path). Segments share the public-key character class.

func ValidateParentPath added in v0.17.0

func ValidateParentPath(parent string) error

ValidateParentPath validates a `/`-separated parent command path as supplied via --parent. The literal "root" (and the empty string) mean the root command and are accepted as-is; every other segment must be a valid command name.

func ValidateReleaseSourceType added in v0.33.0

func ValidateReleaseSourceType(sourceType string) error

ValidateReleaseSourceType restricts the manifest release-source provider to the enum the skeleton assets support: "github", "gitlab", or empty for the host-derived default. "gitea" and "bitbucket" are reserved for the forge adapters and rejected until skeleton asset sets exist.

func ValidateRepo

func ValidateRepo(repo string) error

ValidateRepo enforces Go module path rules: a domain-style first component followed by one or more `[a-zA-Z0-9._~-]+` path segments, no leading/trailing `/`, and no `..` segments. `go mod tidy` would also reject invalid paths, but failing early surfaces a useful error at generation time rather than at first build.

func ValidateRepoName added in v0.33.0

func ValidateRepoName(name string) error

ValidateRepoName enforces the shape of the manifest's bare repository name (release_source.repo — a single path segment, unlike the CLI --repo module path handled by ValidateRepo). The value is joined into `{{ .Repo }}` / `{{ .ModulePath }}` and rendered raw into CI-executed files (.gitlab-ci.yml, .goreleaser.yaml), so quotes, whitespace, brackets, and separators are all outside the class.

func ValidateSelectableFeatureName added in v0.36.0

func ValidateSelectableFeatureName(name string) error

ValidateSelectableFeatureName rejects any name that `gtb generate project --features` cannot act on. Its valid set is wider than ValidateFeatureName's: keychain is a real choice at generation time but cannot be flipped afterwards.

Without it an unknown name was written verbatim into the manifest and then silently dropped at emission, so the generated tool quietly lacked the feature the operator asked for.

func ValidateSigningBackend added in v0.17.0

func ValidateSigningBackend(backend string) error

ValidateSigningBackend accepts an empty string (meaning "default") and otherwise enforces the registered-backend-name character class.

func ValidateSigningExternalKeyEmail added in v0.33.0

func ValidateSigningExternalKeyEmail(email string) error

ValidateSigningExternalKeyEmail accepts an empty string and otherwise enforces an email-shaped character class: single `@`, no whitespace, no control characters. The value is written raw into the `// gtb:signing` annotation of the generated provenance file, so a newline could otherwise break out of the comment line.

func ValidateSigningKMSRegion added in v0.17.0

func ValidateSigningKMSRegion(region string) error

ValidateSigningKMSRegion accepts an empty string and otherwise enforces the AWS region character class.

func ValidateSigningKeyID added in v0.17.0

func ValidateSigningKeyID(keyID string) error

ValidateSigningKeyID accepts an empty string and otherwise enforces the KMS key-id / ARN / alias character class (which also admits the local backend's PEM paths). The value is rendered into the generated .goreleaser.yaml, so quotes, whitespace, and control characters are all outside the class. A literal `..` substring is rejected as defence-in-depth: legitimate KMS ids, ARNs, aliases, and the local backend's relative PEM paths never contain it, mirroring how ValidateCommandName forecloses traversal.

func ValidateSigningKeySource added in v0.33.0

func ValidateSigningKeySource(source string) error

ValidateSigningKeySource restricts the trust-anchor source to the known enum: "embedded", "external", "both", or empty for the framework default.

func ValidateSigningPublicKey added in v0.17.0

func ValidateSigningPublicKey(publicKey string) error

ValidateSigningPublicKey accepts an empty string and otherwise requires a clean, slash-separated path relative to the project root (the manifest documents the field as the path to the armored public-key file, e.g. internal/trustkeys/keys/signing-key-v1.asc). A single leading `./` is normalised away as a friendliness affordance, so `./key.asc` is treated as `key.asc`. Absolute paths, `..` escapes, backslashes, and any other unclean forms are still rejected — the path must resolve inside the project root.

func ValidateSlackChannel

func ValidateSlackChannel(channel string) error

ValidateSlackChannel accepts an empty string and otherwise enforces Slack's own channel-name rules — lowercase, alphanumeric, hyphens, 1–80 characters.

func ValidateSlackTeam

func ValidateSlackTeam(team string) error

ValidateSlackTeam accepts an empty string and otherwise enforces Slack's workspace-name rules.

func ValidateTeamsChannel

func ValidateTeamsChannel(channel string) error

ValidateTeamsChannel accepts an empty string and otherwise enforces generic "safe for YAML and Markdown" rules: bounded length, no control characters, no template-brace sequences.

func ValidateTeamsTeam

func ValidateTeamsTeam(team string) error

ValidateTeamsTeam mirrors ValidateTeamsChannel.

func ValidateTelemetryEndpoint

func ValidateTelemetryEndpoint(endpoint string) error

ValidateTelemetryEndpoint accepts an empty string (meaning "no endpoint") and otherwise requires a syntactically valid HTTP or HTTPS URL, bounded in length and free of control characters.

func ValidateTemplateSource added in v0.18.0

func ValidateTemplateSource(ts *TemplateSource) error

ValidateTemplateSource validates a single manifest templates entry: the type discriminator, the location character class (no traversal), the ref/SHA shape, and the optional name. It is the gate that forecloses a tampered manifest driving a fetch or write outside the rules.

func ValidateUpdateCheckInterval added in v0.18.0

func ValidateUpdateCheckInterval(interval string) error

ValidateUpdateCheckInterval accepts an empty string (meaning "use the framework default of 24h") and otherwise requires a valid, non-negative Go duration (as understood by time.ParseDuration, e.g. "24h", "168h", "30m"). The value is rendered into the generated tool's props.Tool.UpdateCheckInterval as a time.Duration expression, so a malformed or negative value is rejected rather than silently falling back. A length cap bounds the parse input.

func ValidateUpdatePolicy added in v0.18.0

func ValidateUpdatePolicy(policy string) error

ValidateUpdatePolicy accepts an empty string (meaning "use the framework default of disabled") and otherwise requires one of the three known posture values: disabled, prompt, or enabled. The value selects a typed props.UpdatePolicy constant rendered into the generated tool, so an unknown value is rejected rather than silently treated as disabled.

Types

type CommandContext

type CommandContext struct {
	// Identity
	Name       string
	ParentPath []string // empty = direct child of root

	// Display
	Short string
	Long  string

	// Routing / feature options
	Aliases              []string
	Args                 string
	WithAssets           bool
	WithInitializer      bool
	WithConfigValidation bool
	PersistentPreRun     bool
	PreRun               bool
	Protected            *bool
	MCPEnabled           *bool // tri-state MCP exposure; mirrors Protected
	Hidden               bool

	// Project-level settings (carried from the originating generator).
	//
	// Every one of these must be threaded through ToConfig as well as named
	// here. Overwrite was declared on Config but missing from this type, so
	// swapping g.config for a command context silently reset --overwrite to
	// its "ask" default for every command file in the run (issue #13). Taking
	// the whole *Config in buildCommandContext keeps the omission visible in
	// one place rather than spread across four call sites.
	ProjectPath string
	DryRun      bool
	Force       bool
	UpdateDocs  bool
	Overwrite   string
}

CommandContext holds the fully resolved configuration for a single command generation or regeneration pass. It is a value type so recursive invocations cannot accidentally share or mutate each other's state.

func (CommandContext) ToConfig

func (c CommandContext) ToConfig() *Config

ToConfig converts the CommandContext into a *Config suitable for constructing a Generator scoped to this specific command.

type CommandFlag

type CommandFlag struct {
	Default       string
	DefaultIsCode bool
	Description   string
	Hidden        bool
	Name          string
	Persistent    bool
	Required      bool
	Shorthand     string
	Type          string
}

type CommandPipeline

type CommandPipeline struct {
	// contains filtered or unexported fields
}

CommandPipeline owns the ordered post-generation steps that are shared by both generate command and regenerate project. Constructing a pipeline and calling Run centralises all registration, hash, manifest, and documentation logic so a fix in one place applies to both entrypoints.

func (*CommandPipeline) Run

Run executes the pipeline steps in order for the given command data and directory. Fatal steps (asset generation) return an error immediately. Advisory steps (registration, manifest) log a warning and accumulate into PipelineResult so callers can inspect partial failures.

type Config

type Config struct {
	Agentless  bool
	AIModel    string
	AIProvider string
	// MaxSteps bounds the autonomous repair agent's ReAct loop. Zero uses the
	// framework default (gochat.DefaultMaxSteps). Raise it for complex commands
	// the agent cannot finish within the default budget.
	MaxSteps int
	// NonInteractive withholds the repair agent's query_user tool so a
	// generation never blocks for input (CI / --non-interactive).
	NonInteractive bool
	Aliases        []string
	Args           string
	DryRun         bool
	// GitInit controls the post-generation git step on `generate project`
	// (init + stage + initial commit). It is opt-out: the CLI sets it true by
	// default and false under --no-git. Only honoured by GenerateSkeleton.
	GitInit bool
	// GitPush, when true (--push), adds the derived remote as origin and pushes
	// the initial commit. Opt-in; requires GitInit. Push failures are non-fatal.
	GitPush bool
	// GitBranch is the default branch the initial commit lands on (default
	// "main", overridable via --git-branch).
	GitBranch        string
	Flags            []string
	Force            bool
	Hidden           bool
	Overwrite        string // allow, deny, or ask (default ask)
	Long             string
	Name             string
	Parent           string
	Path             string
	PersistentPreRun bool
	PreRun           bool
	Prompt           string
	Protected        *bool
	MCPEnabled       *bool // tri-state MCP exposure; mirrors Protected
	ScriptPath       string
	Short            string
	UpdateDocs       bool
	// PublicAPI marks the module as publicly published (the --public-api flag),
	// so generated package docs defer their API reference to pkg.go.dev. Default
	// false: the reference is stubbed to a local `go doc` hint (no dead links for
	// a private/unpublished module). The manifest module_published property is the
	// persistent equivalent.
	PublicAPI bool
	// NoAIAttribution, when true (the --no-ai-attribution flag on `generate
	// docs`), flips the documentation system prompt so the frontmatter `authors:`
	// field carries the project's human author(s) only — the model is instructed
	// to add no AI/model/assistant identity. Default false: AI attribution is
	// additive (existing human authors preserved, AI model appended as a
	// co-author). See docs.go authorsDirectives and issue #7.
	NoAIAttribution      bool
	WithAssets           bool
	WithConfigValidation bool
	WithInitializer      bool
}

type DryRunResult

type DryRunResult struct {
	Created  []FilePreview `json:"created,omitempty"`
	Modified []FilePreview `json:"modified,omitempty"`
	// Actions describes non-file side effects the run would perform (e.g. the
	// post-generation git init/commit/push), surfaced as plain text lines.
	Actions []string `json:"actions,omitempty"`
}

DryRunResult contains the preview of planned file operations.

func (*DryRunResult) Print

func (r *DryRunResult) Print(w io.Writer)

Print writes a human-readable preview of the dry-run result to w.

type ExternalCommandSpec added in v0.34.0

type ExternalCommandSpec = ManifestExternalCommand

ExternalCommandSpec is the input to AttachExternalCommand: one declarative external-module attachment to record. It mirrors the stored manifest form.

type FilePreview

type FilePreview struct {
	Path    string `json:"path"`
	Content []byte `json:"content,omitempty"`
	Diff    string `json:"diff,omitempty"`
}

FilePreview represents a single file operation in a dry run.

type Generator

type Generator struct {
	// contains filtered or unexported fields
}

func New

func New(p *props.Props, cfg *Config) *Generator

func (*Generator) AddTemplateSource added in v0.18.0

func (g *Generator) AddTemplateSource(ctx context.Context, ts TemplateSource) error

AddTemplateSource appends a source to the manifest (rejecting a duplicate name) and regenerates so the overlay is applied and the pin/hashes are recorded. The supplied source is validated first.

func (*Generator) ApplyFeatures added in v0.18.0

func (g *Generator) ApplyFeatures(ctx context.Context, desired map[string]bool) ([]string, error)

ApplyFeatures flips the requested built-in features in the manifest's properties.features block and re-renders the generated root command so its props.SetFeatures(...) wiring matches. desired maps a toggleable feature name to its requested enabled state (the same method serves the single-name CLI path and the multi-select wizard).

The manifest is normalised against the framework defaults: an entry is kept only when it differs from the default, so returning a feature to its default state removes the entry and the rendered root drops the now-redundant toggle (and the whole SetFeatures call when nothing differs). Unknown names are a hard error. It returns the feature names that actually changed — an empty result means every requested feature was already in the requested state, and nothing is written.

func (*Generator) AttachExternalAdapter added in v0.34.0

func (g *Generator) AttachExternalAdapter(ctx context.Context) error

AttachExternalAdapter scaffolds the author-owned adapter (pkg/cmd/external/ attach.go) if absent — never overwriting an existing one — sets the adapter manifest flag, and re-renders the root to spread external.Commands(p) into NewCmdRoot. The author then fills in Commands to attach any shape the declarative vocabulary cannot express.

func (*Generator) AttachExternalCommand added in v0.34.0

func (g *Generator) AttachExternalCommand(ctx context.Context, spec ExternalCommandSpec) error

AttachExternalCommand records a declarative external-command attachment in the manifest, re-renders the root so the attach calls are wired in, and (on a real filesystem) pins the module require via `go get module@version` and tidies. The attachment is manifest-driven, so it survives every future regenerate / enable / disable — replacing the cmd/<tool>/main.go + .gtb/ignore workaround.

func (*Generator) CheckIgnorePaths added in v0.34.0

func (g *Generator) CheckIgnorePaths(paths []string) []IgnoreCheckResult

CheckIgnorePaths resolves each path against the project's .gtb/ignore rules and returns the winning rule for each. It reads the ignore file fresh; it does not touch the manifest, so it works even before the first regenerate.

func (*Generator) CurrentFeatures added in v0.18.0

func (g *Generator) CurrentFeatures() ([]ManifestFeature, error)

CurrentFeatures returns the project's current manifest feature entries so a caller (e.g. the enable/disable wizard) can present the current state. A project that has never toggled a feature returns an empty slice (every feature is at its framework default).

func (*Generator) CurrentSigning added in v0.15.1

func (g *Generator) CurrentSigning() (ManifestSigning, error)

CurrentSigning returns the project's current manifest signing block, so a caller (e.g. `gtb enable signing`) can merge flag overrides onto the existing posture rather than replacing it. A project that has never enabled signing returns the zero ManifestSigning.

func (*Generator) DetachExternalCommand added in v0.34.0

func (g *Generator) DetachExternalCommand(ctx context.Context, module string) error

DetachExternalCommand removes the declarative attachment for the given module, re-renders the root (dropping its wiring), and — on a real filesystem — tidies so the now-unused require is pruned from go.mod.

func (*Generator) DisableSigning added in v0.14.0

func (g *Generator) DisableSigning(ctx context.Context) error

DisableSigning sets signing.enabled = false in the manifest and selectively regenerates: it drops the Signing: field from the root command and removes the generated signing.go. It never deletes internal/trustkeys or any author-added *.asc.

func (*Generator) DivergedUnignoredFiles added in v0.34.0

func (g *Generator) DivergedUnignoredFiles() ([]string, error)

DivergedUnignoredFiles returns the tracked files whose on-disk content no longer matches the hash recorded in the manifest AND which no ignore rule covers — precisely the set that will raise a conflict prompt on the next regenerate. Files that are ignored, or missing on disk, are excluded. It errors when no manifest exists. Backs the `doctor` diverged-files check.

func (*Generator) EnableRealTemplateClone added in v0.18.0

func (g *Generator) EnableRealTemplateClone() *Generator

EnableRealTemplateClone wires the production provider-aware git clone for custom template sources. Call this on a Generator before resolving git sources in production paths; tests inject a fake via WithTemplateClone instead. Returns the Generator for chaining.

func (*Generator) EnableSigning added in v0.14.0

func (g *Generator) EnableSigning(ctx context.Context, signing ManifestSigning) error

EnableSigning sets the manifest signing posture, then selectively regenerates only the signing-affected files: it writes the trustkeys package, keys/.gitkeep and signing.go, and re-renders the root command (pkg/cmd/root/cmd.go) to add the Signing: field. It does not run a full regenerate — unrelated files are left untouched.

func (*Generator) FeatureEnabled added in v0.18.0

func (g *Generator) FeatureEnabled(name string) (bool, error)

FeatureEnabled reports whether the named feature is currently enabled in the project, honouring a manifest override and otherwise falling back to the framework default.

func (*Generator) FindCommandParentPath

func (g *Generator) FindCommandParentPath(name string) ([]string, error)

func (*Generator) Generate

func (g *Generator) Generate(ctx context.Context) error

func (*Generator) GenerateCommandFile

func (g *Generator) GenerateCommandFile(ctx context.Context, cmdDir string, data *templates.CommandData) error

func (*Generator) GenerateDocs

func (g *Generator) GenerateDocs(ctx context.Context, target string, isPackage bool) error

GenerateDocs generates documentation for the command or package.

func (*Generator) GenerateDryRun

func (g *Generator) GenerateDryRun(ctx context.Context) (*DryRunResult, error)

GenerateDryRun previews what Generate would do without writing to disk.

func (*Generator) GenerateSkeleton

func (g *Generator) GenerateSkeleton(ctx context.Context, config SkeletonConfig) error

func (*Generator) GenerateSkeletonDryRun

func (g *Generator) GenerateSkeletonDryRun(ctx context.Context, config SkeletonConfig) (*DryRunResult, error)

GenerateSkeletonDryRun previews what GenerateSkeleton would do without writing to disk.

func (*Generator) ListExternalCommands added in v0.34.0

func (g *Generator) ListExternalCommands() ([]ManifestExternalCommand, bool, error)

ListExternalCommands returns the declared external-command attachments and whether the adapter channel is wired.

func (*Generator) ListIgnoreRules added in v0.34.0

func (g *Generator) ListIgnoreRules() (*IgnoreListing, error)

ListIgnoreRules resolves the project's ignore rules against the files tracked in the manifest: each tracked file is attributed to its winning rule, and any rule matching no tracked file is surfaced as stale. It errors when no manifest exists (there is nothing to resolve against).

"Tracked" means Manifest.TrackedFiles — both hash namespaces. Resolving against the project-level map alone made a live rule covering a command's cmd.go report as stale while `ignore check` reported the same path ignored (issue #13).

func (*Generator) ListTemplateSources added in v0.18.0

func (g *Generator) ListTemplateSources() ([]TemplateSource, error)

ListTemplateSources returns the template sources recorded in the project manifest, in layer order.

func (*Generator) RegenerateCommand added in v0.17.0

func (g *Generator) RegenerateCommand(ctx context.Context, cmd ManifestCommand, parentPath []string) error

RegenerateCommand regenerates a single command's cmd.go from its full ManifestCommand record and persists the refreshed cmd.go hash back to the manifest. It reuses the exact mapping the `regenerate project` path uses (prepareRegenerationData → performGeneration → postGenerate), so a command's aliases, persistent/required/shorthand flags, and pre-run hooks survive the regeneration rather than being dropped by a hand-built partial CommandData.

Unlike regenerateCommandRecursive it does NOT recurse into subcommands: it is the entrypoint for the targeted `generate add-flag` regeneration, which must only rewrite the command whose flag set changed. Child registrations in the regenerated cmd.go are preserved by the pipeline's reRegisterChildCommands step.

func (*Generator) RegenerateManifest

func (g *Generator) RegenerateManifest(ctx context.Context) error

func (*Generator) RegenerateProject

func (g *Generator) RegenerateProject(ctx context.Context) error

func (*Generator) RegenerateProjectDryRun

func (g *Generator) RegenerateProjectDryRun(ctx context.Context) (*DryRunResult, error)

RegenerateProjectDryRun previews what RegenerateProject would do without writing to disk.

func (*Generator) Remove

func (g *Generator) Remove(ctx context.Context) error

func (*Generator) RemoveTemplateSource added in v0.18.0

func (g *Generator) RemoveTemplateSource(ctx context.Context, name string) error

RemoveTemplateSource drops a named source from the manifest and regenerates. Removing the source restores any embedded scaffold a `replaces:` had suppressed (the embedded files re-enter the walk) and drops the source's tracked overlay output from the manifest. The on-disk overlay files themselves are left in place unless a regenerated embedded file overwrites them — a clean, reversible swap consistent with the rest of regenerate.

func (*Generator) SealedTrackedFiles added in v0.37.0

func (g *Generator) SealedTrackedFiles() ([]string, error)

SealedTrackedFiles returns the manifest-tracked files a `sealed` rule covers.

They are reported separately from drift: a sealed path is not a file that has wandered, it is one the generator has been told never to write. What makes it worth surfacing is that sealing also blocks the wiring, so a sealed parent silently loses any subcommand added since — the command compiles away to nothing rather than failing loudly (spec 0188 D7).

func (*Generator) SetMCPEnabled added in v0.21.0

func (g *Generator) SetMCPEnabled(ctx context.Context, commandPath string, enabled bool) error

SetMCPEnabled records a command's MCP-exposure decision in the manifest and re-renders that single command's cmd.go so the generated setup.ExcludeFromMCP / setup.IncludeInMCP marker matches. It is the engine behind `gtb enable mcp` (enabled=true) and `gtb disable mcp` (enabled=false).

Unlike SetProtection (manifest-only), this changes generated code, so it drives the targeted RegenerateCommand path. A protected command is refused with ErrCommandProtected rather than silently overwritten — the operator must unprotect it first.

func (*Generator) SetProtection

func (g *Generator) SetProtection(ctx context.Context, commandName string, protected bool) error

func (*Generator) UpdateTemplateSource added in v0.18.0

func (g *Generator) UpdateTemplateSource(ctx context.Context, name string) error

UpdateTemplateSource re-resolves a named git source's ref to a new SHA (clearing the old pin so the clone re-resolves) and regenerates. This is the only pin-advancing path (D7). A local source has no pin to advance; updating it simply regenerates against the current on-disk tree.

func (*Generator) WithTemplateClone added in v0.18.0

func (g *Generator) WithTemplateClone(fn templateCloneFunc) *Generator

WithTemplateClone injects the git template-source clone implementation. Primarily for tests (a local bare remote or a fake); production code calls EnableRealTemplateClone to wire the provider-aware pkg/vcs/repo clone.

type IgnoreCheckResult added in v0.34.0

type IgnoreCheckResult struct {
	Path    string // the queried path
	Ignored bool   // final decision under last-match-wins + ! negation
	Matched bool   // whether any rule matched at all
	Rule    string // the winning rule line as written (empty when Matched is false)
	Negated bool   // whether the winning rule was a negation
	// State is the resolved tier: managed, ignored or sealed. Ignored stays for
	// the render question specifically; State is what distinguishes a path the
	// generator may still wire from one it must not touch at all (spec 0188 D7).
	State RuleState
}

IgnoreCheckResult reports the ignore decision for a single path, naming the rule that decided it. Backs `gtb ignore check`.

type IgnoreListEntry added in v0.34.0

type IgnoreListEntry struct {
	Path    string
	Ignored bool
	Rule    string // winning rule line (empty when no rule matched)
	State   RuleState
}

IgnoreListEntry is one tracked file and its ignore status, attributed to the winning rule. Backs `gtb ignore list`.

type IgnoreListing added in v0.34.0

type IgnoreListing struct {
	Rules      []string          // active rule lines, in file order
	Entries    []IgnoreListEntry // tracked files governed by a rule, sorted by path
	StaleRules []string          // rules that match no tracked file
}

IgnoreListing is the resolved view `gtb ignore list` prints: every active rule, the tracked files each governs, and any rule matching no tracked file.

type IgnoreRules

type IgnoreRules struct {
	// contains filtered or unexported fields
}

IgnoreRules holds compiled ignore patterns from a .gtb/ignore file. Patterns are evaluated top-to-bottom; later patterns override earlier ones. Negation (!) re-includes a previously excluded file.

func LoadIgnoreRules

func LoadIgnoreRules(fs afero.Fs, projectPath string) *IgnoreRules

LoadIgnoreRules reads the .gtb/ignore file from the project directory. Returns empty rules (nothing ignored) if the file doesn't exist.

func (*IgnoreRules) Explain added in v0.34.0

func (r *IgnoreRules) Explain(relPath string) (rule string, negated, matched bool)

Explain evaluates all rules top-to-bottom and returns the winning rule for the given relative path: the last rule that matched (last-match-wins), the original rule line as written (with any ! or trailing /), whether that rule was a negation, and whether any rule matched at all. When matched is false the path is governed by no rule (and is therefore not ignored). This backs `gtb ignore check`, which must name the deciding rule — a question the flat file cannot answer, because negation means the winner can be a later ! line.

func (*IgnoreRules) IsIgnored

func (r *IgnoreRules) IsIgnored(relPath string) bool

IsIgnored reports whether the generator must not *render* the path — rewrite it wholesale from source. A sealed path is also ignored: sealing is a superset.

It deliberately does not answer the wiring question. A caller that performs a localised, structure-aware edit asks IsSealed instead (spec 0188 D2).

func (*IgnoreRules) IsSealed added in v0.37.0

func (r *IgnoreRules) IsSealed(relPath string) bool

IsSealed reports whether the generator must not touch the path at all, wiring included. This is the predicate the localised writers consult — subcommand registration, child re-registration, hook-stub injection — because refusing those leaves a manifest declaring a child its parent never registers, or a cmd.go referencing a hook stub that does not exist: a project that does not build. A plain ignore rule is not enough to ask for that; `sealed` is.

func (*IgnoreRules) Rules added in v0.34.0

func (r *IgnoreRules) Rules() []string

Rules returns the original rule lines in file order (with any ! or trailing / preserved). It backs `gtb ignore list`, which must surface every active rule and flag those that currently match no tracked file.

func (*IgnoreRules) State added in v0.37.0

func (r *IgnoreRules) State(relPath string) RuleState

State evaluates all rules top-to-bottom and returns what may be done to the path: managed, ignored, or sealed. Later rules override earlier ones, and a negation (!) returns a path all the way to managed.

The `sealed` attribute is tracked separately from the ignore decision so that a rule which says nothing about sealing leaves an earlier rule's decision standing, and `-sealed` can drop a path from sealed back to ignored without re-managing it (spec 0188 D4).

type Manifest

type Manifest struct {
	Properties    ManifestProperties    `yaml:"properties"`
	ReleaseSource ManifestReleaseSource `yaml:"release_source"`
	Version       ManifestVersion       `yaml:"version"`
	Hashes        map[string]string     `yaml:"hashes,omitempty"` // project-level file hashes (relative path → SHA256)
	Commands      []ManifestCommand     `yaml:"commands,omitempty"`
}

func DecodeManifestFile added in v0.17.0

func DecodeManifestFile(fs afero.Fs, manifestPath string) (*Manifest, error)

DecodeManifestFile reads and unmarshals the manifest at the given manifest.yaml path from fs. It is the single read/decode helper routed through by every manifest-loading site (including the generate-flag command in internal/cmd), so the read+unmarshal boilerplate — and its error wording — lives in one place.

func (*Manifest) GetReleaseSource

func (m *Manifest) GetReleaseSource() (sourceType, owner, repo string)

GetReleaseSource returns the release source type, owner, and repo.

func (*Manifest) TrackedFiles added in v0.37.0

func (m *Manifest) TrackedFiles() map[string]string

TrackedFiles returns every file the manifest records a hash for, keyed by project-relative, slash-separated path.

A manifest keeps hashes in two places: project-level skeleton files in Hashes, and per-command generated files (cmd.go, init.go, main_test.go) in each command's own Hashes map, keyed by bare filename. Consumers that walked only the first — `gtb ignore list` and the `doctor` diverged-files check — were structurally blind to exactly the files that raise a conflict on regenerate, so a live ignore rule covering a command file was reported stale and doctor passed a project that could not be regenerated (issue #13).

The deprecated per-command Hash field is folded in as cmd.go, matching what the conflict resolver reads.

type ManifestBootstrap added in v0.29.0

type ManifestBootstrap struct {
	// AutoInitialise runs a non-interactive init to write the default config
	// when it is missing, instead of failing. Defaults to false.
	AutoInitialise bool `yaml:"auto_initialise,omitempty"`
	// SkipConfigCheck lists commands (by Name() or full CommandPath()) whose
	// missing-config gate is relaxed to a tolerant load so they own bootstrap.
	SkipConfigCheck []string `yaml:"skip_config_check,omitempty"`
}

ManifestBootstrap holds config-bootstrap lifecycle policy for generated tools — the manifest representation of props.Tool.Bootstrap. Empty scaffolds nothing (framework default: a missing config is a hard error when init is enabled). See https://gitlab.com/phpboyscout/go-tool-base/-/wikis/specs/0114-bootstrap-auto-initialise-skip-config-check.

type ManifestCI added in v0.18.0

type ManifestCI struct {
	// ComponentSource is the include base for the phpboyscout/cicd
	// components in the scaffolded .gitlab-ci.yml. Empty means "use the
	// framework default" (DefaultCICDComponentSource,
	// gitlab.com/phpboyscout/cicd); a mirrored/self-hosted downstream sets
	// this to repoint the include base. Defaulted on render so a manifest
	// with no ci block still produces a complete pipeline.
	ComponentSource string `yaml:"component_source,omitempty"`
}

ManifestCI holds CI-pipeline configuration for generated tools. It is the manifest representation of the scaffolded GitLab pipeline's configurable inputs. Currently it carries only the phpboyscout/cicd component source so a mirrored or self-hosted downstream can repoint the include base; the component versions are pinned by a generator constant kept in lockstep with the framework (not manifest-driven). See https://gitlab.com/phpboyscout/go-tool-base/-/wikis/specs/0082-generator-gitlab-ci-refresh.

type ManifestCommand

type ManifestCommand struct {
	Name                 string            `yaml:"name"`
	Description          MultilineString   `yaml:"description"`
	LongDescription      MultilineString   `yaml:"long_description,omitempty"`
	Aliases              []string          `yaml:"aliases,omitempty"`
	Hidden               bool              `yaml:"hidden,omitempty"`
	Args                 string            `yaml:"args,omitempty"`
	Hash                 string            `yaml:"hash,omitempty"` // Deprecated: use Hashes
	Hashes               map[string]string `yaml:"hashes,omitempty"`
	WithAssets           bool              `yaml:"with_assets,omitempty"`

	WithConfigValidation bool              `yaml:"with_config_validation,omitempty"`
	Protected            *bool             `yaml:"protected,omitempty"`
	// MCPEnabled is the tri-state MCP-exposure decision for this command:
	// nil = inherit (default exposed), true = explicitly exposed, false =
	// excluded from the MCP tool surface. Build-time only; see
	// https://gitlab.com/phpboyscout/go-tool-base/-/wikis/specs/0089-mcp-command-exposure-gating.
	MCPEnabled *bool `yaml:"mcp_enabled,omitempty"`

	PersistentPreRun  bool              `yaml:"persistent_pre_run,omitempty"`
	PreRun            bool              `yaml:"pre_run,omitempty"`

	RequiredTogether  [][]string        `yaml:"required_together,omitempty"`
	Flags             []ManifestFlag    `yaml:"flags,omitempty"`
	Commands          []ManifestCommand `yaml:"commands,omitempty"`
	Warning           string            `yaml:"-"` // Used for comments
}

func (ManifestCommand) MarshalYAML

func (c ManifestCommand) MarshalYAML() (any, error)

type ManifestCommandUpdate

type ManifestCommandUpdate struct {
	Name                 string
	Description          string
	LongDescription      string
	Aliases              []string
	Args                 string
	Hashes               map[string]string
	Flags                []ManifestFlag
	WithAssets           bool
	WithInitializer      bool
	WithConfigValidation bool
	PersistentPreRun     bool
	PreRun               bool
	Protected            *bool
	MCPEnabled           *bool
	Hidden               bool
}

ManifestCommandUpdate carries all fields that updateCommandRecursive writes to a ManifestCommand entry. Adding a new manifest field means adding it here rather than extending the function signature.

type ManifestExternalAttach added in v0.34.0

type ManifestExternalAttach struct {
	// Constructor is the exported symbol to call, e.g. "NewCmdSign".
	Constructor string `yaml:"constructor"`
	// Args are injection tokens from the closed vocabulary
	// ([templates.ExternalArgTokens]), rendered in order. Empty means a
	// zero-argument constructor.
	Args []string `yaml:"args,omitempty"`
	// Wrap is true when Constructor returns *cobra.Command and must be wrapped
	// via setup.Wrap("", …); false when it returns *setup.Command and is
	// attached directly. It describes the constructor's return type, not gating
	// — declarative attachments are un-gated (always-on) in v1.
	Wrap bool `yaml:"wrap"`
	// Name, if set, is the expected top-level command name, used only for
	// best-effort collision detection. It does not affect the rendered call.
	Name string `yaml:"name,omitempty"`
}

ManifestExternalAttach describes a single external constructor call to render onto the generated root.

type ManifestExternalCommand added in v0.34.0

type ManifestExternalCommand struct {
	// Module is the Go module path providing the commands, e.g.
	// "gitlab.com/phpboyscout/go/signing-cli". Used for the go.mod require.
	Module string `yaml:"module"`
	// Version is the module version to require, e.g. "v0.1.0". Required — an
	// explicit pin; there is no implicit latest resolution.
	Version string `yaml:"version"`
	// ImportPath is the package to import for the constructors. Defaults to
	// Module when empty (the signing-cli case: the constructors live in the
	// module root package).
	ImportPath string `yaml:"import_path,omitempty"`
	// Alias is the import alias for ImportPath in the generated root. Defaults
	// to the import path's base name when empty.
	Alias string `yaml:"alias,omitempty"`
	// Attach lists the constructor calls to render onto the root. At least one
	// entry is required — a module with nothing to attach is meaningless.
	Attach []ManifestExternalAttach `yaml:"attach"`
}

ManifestExternalCommand declares one external module whose Cobra command builders are attached to the generated project's root (the declarative channel). It carries a provenance pin (module + version) and the call descriptors the generator needs to render each attachment, and holds no behaviour — mirroring TemplateSource.

type ManifestFeature

type ManifestFeature struct {
	Name    string `yaml:"name"`
	Enabled bool   `yaml:"enabled"`
}

type ManifestFlag

type ManifestFlag struct {
	Name          string          `yaml:"name"`

	Description   MultilineString `yaml:"description"`
	Persistent    bool            `yaml:"persistent,omitempty"`
	Shorthand     string          `yaml:"shorthand,omitempty"`

	Required      bool            `yaml:"required,omitempty"`
	Hidden        bool            `yaml:"hidden,omitempty"`
	Warning       string          `yaml:"-"` // Used for comments

	// It is declared here rather than hand-wired in the scaffolded main because

	ExternalCommandsAdapter bool `yaml:"external_commands_adapter,omitempty"`
}

func (ManifestProperties) ResolvedDocsLayout added in v0.24.0

func (p ManifestProperties) ResolvedDocsLayout() string

ResolvedDocsLayout returns the effective documentation layout, defaulting an empty or unrecognised value to DocsLayoutFlat for backward compatibility with projects generated before the docs_layout field existed.

type ManifestReleaseSource

type ManifestReleaseSource struct {
	Type    string `yaml:"type"`
	Host    string `yaml:"host"`
	Owner   string `yaml:"owner"`
	Repo    string `yaml:"repo"`
	Private bool   `yaml:"private,omitempty"`
}

type ManifestSigning added in v0.14.0

type ManifestSigning struct {
	// Enabled gates all signing scaffolding. Defaults to false; set true
	// by `gtb enable signing` or `gtb generate project --signing`.
	Enabled bool `yaml:"enabled,omitempty"`
	// ExternalKeyEmail derives the WKD URL and enables the external
	// (WKD) trust-anchor leg. Empty leaves verification embedded-only.
	ExternalKeyEmail string `yaml:"external_key_email,omitempty"`
	// RequireSignature fails an update closed when no valid signature is
	// present. Stays false until a signed release has shipped (the N+1
	// rollout); only ever flipped via `gtb enable signing --require-signature`.
	RequireSignature bool `yaml:"require_signature,omitempty"`
	// KeySource selects the trust-anchor source: "embedded", "external"
	// or "both" (the framework default when empty).
	KeySource string `yaml:"key_source,omitempty"`
	// RequireExternalCrosscheck fails closed when the external (WKD)
	// resolver is unreachable, rather than degrading to embedded-only.
	RequireExternalCrosscheck bool `yaml:"require_external_crosscheck,omitempty"`
	// Backend selects the `gtb sign` backend the generated release
	// pipeline signs with (e.g. "aws-kms", "local"). Defaults to
	// "aws-kms" when a key id is recorded. Drives the GoReleaser signs
	// block; backend-specific args (e.g. kms_region) are emitted only for
	// the backends that take them.
	Backend string `yaml:"backend,omitempty"`
	// KeyID is the backend-specific signing key identifier passed to
	// `gtb sign --key-id` (a KMS id/ARN/alias, or a PEM path for the
	// local backend). Recording it is what turns the GoReleaser signs
	// block on; empty leaves the release pipeline untouched.
	KeyID string `yaml:"key_id,omitempty"`
	// KMSRegion is the AWS region for the aws-kms backend
	// (`gtb sign --kms-region`). Defaults to "eu-west-2". Ignored by
	// backends that don't take a region.
	KMSRegion string `yaml:"kms_region,omitempty"`
	// PublicKey is the path to the armored public-key file the signature
	// identifies (`gtb sign --public-key`), relative to the project root.
	// Defaults to the embedded-key convention
	// internal/trustkeys/keys/signing-key-v1.asc.
	PublicKey string `yaml:"public_key,omitempty"`
}

ManifestSigning holds self-update signature-verification configuration for generated tools. It is the manifest representation of the generated internal/trustkeys package, the props.Tool.Signing wiring, and the generated signing.go enforcement defaults. Signing is disabled by default — a project with no signing block scaffolds nothing signing-related. See https://gitlab.com/phpboyscout/go-tool-base/-/wikis/specs/0071-signing-generator-feature.

func ApplySigningDefaults added in v0.15.0

func ApplySigningDefaults(s ManifestSigning) ManifestSigning

ApplySigningDefaults fills the release-pipeline defaults when a signing key id has been recorded, so the generated GoReleaser signs block is always complete. With no key id the release pipeline is left untouched. Exported so the generate command can default at its boundary, keeping the persisted manifest and the rendered .goreleaser.yaml consistent — the same defaulting EnableSigning applies.

type ManifestTelemetry

type ManifestTelemetry struct {
	Endpoint     string `yaml:"endpoint,omitempty"`
	OTelEndpoint string `yaml:"otel_endpoint,omitempty"`
}

ManifestTelemetry holds telemetry configuration for generated tools.

type ManifestVersion

type ManifestVersion struct {
	GoToolBase string `yaml:"gtb"`
}

type MultilineString

type MultilineString string

func (MultilineString) MarshalYAML

func (s MultilineString) MarshalYAML() (any, error)

type PipelineOptions

type PipelineOptions struct {
	SkipAssets        bool // do not generate asset files
	SkipDocumentation bool // do not run documentation generation
	SkipRegistration  bool // do not modify the parent cmd.go
}

PipelineOptions controls which steps CommandPipeline executes. The zero value enables all steps.

type PipelineResult

type PipelineResult struct {
	Warnings []StepWarning
}

PipelineResult is returned by CommandPipeline.Run and carries any advisory warnings accumulated during execution. A non-empty Warnings slice does not indicate overall failure — the pipeline continued past those steps.

type RuleState added in v0.37.0

type RuleState int

RuleState is what the rules say may be done to a path. The generator does two different things to a generated file and they warrant different answers (spec 0188): rendering rewrites it from source, while wiring is the localised, structure-aware edit that registers a subcommand in its parent or injects a hook stub into main.go.

const (
	// StateManaged: the generator owns the path. Render and wiring both proceed.
	StateManaged RuleState = iota
	// StateIgnored: a bare rule matched. Rendering is refused. Wiring still
	// proceeds where refusing it would leave the project unbuildable — see
	// IsSealed and spec 0188 D2.
	StateIgnored
	// StateSealed: a rule set the `sealed` attribute. No write of any kind.
	StateSealed
)

func (RuleState) String added in v0.37.0

func (s RuleState) String() string

String renders the state as it appears in `gtb ignore check` / `list`.

type SkeletonConfig

type SkeletonConfig struct {
	Name                  string
	Repo                  string
	Host                  string
	Description           string
	Path                  string
	GoVersion             string // overrides autodetected version when set
	Features              []ManifestFeature
	Private               bool   // true if the repository requires authentication to access
	HelpType              string // "slack", "teams", or ""
	SlackChannel          string
	SlackTeam             string
	TeamsChannel          string
	TeamsTeam             string
	TelemetryEndpoint     string // populated from manifest telemetry.endpoint
	TelemetryOTelEndpoint string // populated from manifest telemetry.otel_endpoint
	EnvPrefix             string // environment variable prefix for config overrides
	// ConfigLayers declares which config-stack layers the project wires. Empty
	// inherits the framework default, which is what every project generated
	// before this field existed does.
	ConfigLayers []string
	Signing      ManifestSigning   // self-update signature-verification posture (disabled by default)
	Bootstrap    ManifestBootstrap // config-bootstrap lifecycle policy (auto-init / skip-config-check)
	// UpdatePolicy is the generated tool's self-update posture baseline
	// (disabled / prompt / enabled). Empty leaves it unset so the framework
	// default (disabled) applies; wired into the generated root command's
	// props.Tool.UpdatePolicy. See https://gitlab.com/phpboyscout/go-tool-base/-/wikis/specs/0087-forced-update-feature.
	UpdatePolicy string
	// UpdateCheckInterval is the generated tool's baseline self-update-check
	// throttle as a Go duration string (e.g. "24h"). Empty leaves it unset so
	// the framework default (24h) applies; wired into the generated root
	// command's props.Tool.UpdateCheckInterval.
	UpdateCheckInterval string
	// CIComponentSource overrides the phpboyscout/cicd include base in the
	// scaffolded GitLab pipeline. Empty falls back to
	// DefaultCICDComponentSource. GitLab-only; ignored for GitHub projects.
	CIComponentSource string
	// Templates carries the custom template-overlay sources (in layer order)
	// through generation. The wizard/flags populate it and
	// writeSkeletonManifest persists it.
	Templates []TemplateSource
}

type StepWarning

type StepWarning struct {
	Step string
	Err  error
}

StepWarning records a non-fatal failure within a pipeline step.

type TemplateContractData added in v0.18.0

type TemplateContractData struct {
	Name              string
	Description       string
	Repo              string
	Host              string
	Org               string
	RepoName          string
	ModulePath        string
	ReleaseProvider   string
	GoVersion         string
	GoToolBaseVersion string
	EnvPrefix         string
	EnabledFeatures   []string
	DisabledFeatures  []string
	Private           bool
	// SigningEnabled / HelpType expose only presence/shape, never secrets.
	SigningEnabled bool
	HelpType       string
}

TemplateContractData is the documented, stable, metadata-only and secret-free subset of skeletonTemplateData exposed to overlay templates. It deliberately excludes any resolved credential, env var, absolute host path, or forge token — the information-disclosure threat. Adding a field is a safe additive change; removing one is a contract-version bump.

func (TemplateContractData) GetReleaseProvider added in v0.18.0

func (d TemplateContractData) GetReleaseProvider() string

GetReleaseProvider satisfies releaseProviderAccessor.

type TemplateDescriptor added in v0.18.0

type TemplateDescriptor struct {
	// Contract is the data-contract version the set targets. Zero is treated
	// as version 1 (the only version) for descriptors that omit it; any
	// value above supportedContractVersion is rejected.
	Contract int `yaml:"contract"`
	// Description is a human-facing summary of the template set.
	Description string `yaml:"description"`
	// Replaces names the embedded scaffolds this set supersedes. Each entry
	// must be a known alias in suppressibleAliases.
	Replaces []string `yaml:"replaces"`
}

TemplateDescriptor is the parsed gtb-template.yaml at a source root. It declares the data-contract version the set targets and the embedded scaffolds it suppresses before the overlay renders. Absent descriptor / empty Replaces ⇒ pure overlay (nothing suppressed).

type TemplateSource added in v0.18.0

type TemplateSource struct {
	// Name is an optional operator-assigned handle used by
	// `gtb template update/remove <name>`. Defaults to the repo/dir base
	// name when unset.
	Name string `yaml:"name,omitempty"`
	// Type is "git" or "local".
	Type TemplateSourceType `yaml:"type"`
	// Location is the forge repo path (org/repo, nested GitLab groups
	// supported) or a full clone URL for git sources, or a filesystem path
	// for local sources.
	Location string `yaml:"location"`
	// Ref is the branch/tag/commit the operator specified, recorded verbatim
	// (provenance). Empty/"" defaults to the source's default branch.
	Ref string `yaml:"ref,omitempty"`
	// Resolved is the commit SHA Ref resolved to at generate time — the pin
	// regenerate reproduces from. Empty for local sources.
	Resolved string `yaml:"resolved,omitempty"`
	// Fingerprint is a content fingerprint of a local source's tree at
	// generate time, so regenerate can warn when the on-disk source drifts.
	// Empty for git sources (the resolved SHA is the pin).
	Fingerprint string `yaml:"fingerprint,omitempty"`
	// Hashes records each rendered overlay file's SHA256 keyed by output
	// relative path, so a source's footprint is self-contained and can be
	// removed cleanly (D5).
	Hashes map[string]string `yaml:"hashes,omitempty"`
}

TemplateSource is the minimal consumer-manifest record for one custom template-overlay source: provenance (where it came from, what ref the operator asked for) plus the pin (the resolved commit SHA for git, a content fingerprint for local) and the per-source rendered-output hashes.

The *behaviour* of a source (which embedded scaffolds it replaces, which data-contract version it targets) lives with the template set in its gtb-template.yaml descriptor, never here — the consumer manifest stays provenance-only so consuming projects do not repeat the author's intent.

func ParseTemplateSpec added in v0.18.0

func ParseTemplateSpec(fs afero.Fs, spec, name string) (TemplateSource, error)

ParseTemplateSpec parses a `<src>@<ref>` spec into a TemplateSource. The `@<ref>` suffix is optional (defaults to the source's default branch for git). The source type is inferred: a value that exists as a directory on fs, or that looks like a filesystem path (starts with ./ ../ / or ~), is a local source; otherwise it is a git source. The parsed entry is validated before return so a malformed spec fails at the CLI boundary.

An explicit name (e.g. from `--name`) overrides the inferred default; pass "" to take the default (the repo/dir base name).

type TemplateSourceType added in v0.18.0

type TemplateSourceType string

TemplateSourceType discriminates the two custom-template source backends.

const (
	// TemplateSourceLocal reads a template overlay directly from a
	// filesystem path. No network, no cache, no SHA pin — a content
	// fingerprint is recorded so regenerate can warn on drift.
	TemplateSourceLocal TemplateSourceType = "local"
	// TemplateSourceGit clones a template overlay from a forge repo (public
	// over https/go-git, private via the configured forge auth) and pins the
	// resolved commit SHA for byte-stable regeneration.
	TemplateSourceGit TemplateSourceType = "git"
)
