)

System/standard environment variable names.

View Source 
const (
	RoleGate    = "gate"    // pass/fail check
	RoleAutofix = "autofix" // rewrites files (formatters)
)

Command roles describe what a command does. Only RoleGate is acted on: sidecar setup marks gate commands for remote execution.

View Source 
const CmdInstall = "install"

CmdInstall is the conventional name for the dependency install command. It has no role of its own but sidecar setup treats it like a gate command.

Variables

View Source 
var ErrNoSuchCommand = errors.New("no such command")

ErrNoSuchCommand reports a command name that is not in the project config.

View Source 
var ValidConfigKeys = map[string]bool{
	"model":              true,
	"useSSHIdentityFile": true,
	"telemetry":          true,
	"notifications":      true,
}

ValidConfigKeys are the keys accepted by "config set" that write to the user config. Credentials (anthropicAPIKey, circleCIToken) are intentionally excluded — users should use "auth set" which validates before storing.

View Source 
var ValidProjectConfigKeys = map[string]bool{
	"orgID":                   true,
	"validation.sidecarImage": true,
}

ValidProjectConfigKeys are the keys accepted by "config set" that write to the project config (.chunk/config.json).

Functions

func AppData added in v0.7.38 

func AppData() (string, error)

AppData returns the chunk data directory, respecting XDG_DATA_HOME.

func AppState added in v0.7.1 

func AppState() (string, error)

AppState returns XDG_STATE_HOME or ~/.local/state.

func Clear added in v0.7.24 

func Clear(key string) error

Clear removes a stored config value by key.

func Dir 

func Dir() (string, error)

Dir returns the chunk config directory, respecting XDG_CONFIG_HOME.

func EnsureInstanceID added in v0.7.117 

func EnsureInstanceID() (uuid.UUID, error)

EnsureInstanceID returns the persisted anonymous instance ID used to associate telemetry events with a single install, generating and saving one on first run.

func GetUserID added in v0.7.159 

func GetUserID() uuid.UUID

GetUserID returns the persisted CircleCI user UUID, or uuid.Nil if none has been saved yet (e.g. the user has not authenticated) or the config cannot be read. Errors are silently swallowed because this is a best-effort telemetry helper — a missing user ID degrades gracefully to anonymous attribution rather than blocking the command.

func IsTelemetry added in v0.7.117 

func IsTelemetry(cfg UserConfig) bool

IsTelemetry reports whether telemetry should be collected, honoring (in order) well-known opt-out environment variables and the persisted telemetry preference. Telemetry is opt-out: it defaults to enabled when no preference has been set.

func MaskKey added in v0.7.24 

func MaskKey(key string) string

MaskKey masks all but the last 4 characters with *.

func Path 

func Path() (string, error)

Path returns the full path to config.json.

func ProjectDataDir added in v0.7.38 

func ProjectDataDir(projectRoot string) (string, error)

ProjectDataDir returns the per-project data directory keyed by projectRoot. The directory name is the hex-encoded SHA-256 of the real absolute path (symlinks resolved via EvalSymlinks, falling back to filepath.Clean), which ensures callers that discover the root via different means — git's --show-toplevel vs. a manual filesystem walk — always hash the same string.

One-time migration: if the resolved path yields an empty directory but the old unresolved path has existing data, the old directory is renamed to the new location so users with symlinked project roots don't silently lose their sidecar/snapshot/event-log state.

func ResolveOrgID added in v0.7.66 

func ResolveOrgID(workDir string) (value, source string)

ResolveOrgID returns the CircleCI org ID for display in config show. Priority: CIRCLECI_ORG_ID env var > orgID in .chunk/config.json for workDir.

func Save 

func Save(cfg UserConfig) error

Save writes the config file, creating the directory with 0o700 and file with 0o600.

func SaveCommand added in v0.7.2 

func SaveCommand(workDir, name, command string) error

SaveCommand upserts a command in .chunk/config.json.

func SaveProjectConfig added in v0.7.2 

func SaveProjectConfig(workDir string, cfg *ProjectConfig) error

SaveProjectConfig writes the config back to .chunk/config.json.

func SaveUserID added in v0.7.159 

func SaveUserID(id uuid.UUID) error

SaveUserID persists the CircleCI user UUID for the current user so it can be attached to telemetry events as the real UserId.

Note: like EnsureInstanceID, this does a Load→Save cycle without a file lock, so concurrent writes from two processes can race. In practice the only caller is the auth flow, which runs once interactively, making the race window negligible.

func LoadEnv(ctx context.Context) (EnvVars, error)

LoadEnv populates an EnvVars struct from the process environment.

type ProjectConfig added in v0.7.2 

type ProjectConfig struct {
	Commands            []Command            `json:"commands,omitempty"`
	VCS                 *VCSConfig           `json:"vcs,omitempty"`

	StopHookMaxAttempts int                  `json:"stopHookMaxAttempts,omitempty"`
	Environment         *envspec.Environment `json:"environment,omitempty"`
}

ProjectConfig is the per-repo configuration stored in .chunk/config.json.

func LoadProjectConfig added in v0.7.2 

func LoadProjectConfig(workDir string) (*ProjectConfig, error)

LoadProjectConfig reads .chunk/config.json from workDir.

func (*ProjectConfig) FindCommand added in v0.7.2 

func (c *ProjectConfig) FindCommand(name string) *Command

FindCommand returns the command with the given name, or nil if not found.

func (*ProjectConfig) HasCommands added in v0.7.2 

func (c *ProjectConfig) HasCommands() bool

HasCommands reports whether any commands are configured.

func (*ProjectConfig) HasRemoteCommands added in v0.7.35 

func (c *ProjectConfig) HasRemoteCommands() bool

func (*ProjectConfig) MarkCommandRemote added in v0.7.151 

func (c *ProjectConfig) MarkCommandRemote(name string) ([]string, error)

MarkCommandRemote marks commands for remote execution. An empty name applies to every configured command except autofix ones: a formatter rewrites files, and on a sidecar those edits never reach the local working tree, so sweeping them in would break the thing silently. Naming one explicitly still marks it, for the caller who means it. Returns the names it changed — commands already marked remote are left out, so an empty slice means there was nothing to do.

func (*ProjectConfig) MarkRemoteCommandsForSidecarSetup added in v0.7.85 

func (c *ProjectConfig) MarkRemoteCommandsForSidecarSetup() bool

MarkRemoteCommandsForSidecarSetup marks install and gate commands for remote execution after a successful sidecar setup. Returns true when any command was updated.

type ResolvedConfig 

type ResolvedConfig struct {
	AnthropicAPIKey       string
	AnthropicAPIKeySource string
	AnthropicBaseURL      string
	CircleCIToken         string
	CircleCITokenSource   string
	CircleCIBaseURL       string
	GitHubToken           string
	GitHubTokenSource     string
	GitHubAPIURL          string

	ModelSource           string
	AnalyzeModel          string
	PromptModel           string
	UseSSHIdentityFile    bool
	Notifications         bool
}

ResolvedConfig holds the final resolved values with their sources.

func Resolve 

func Resolve(flagAPIKey, flagModel string, _ bool) (ResolvedConfig, error)

Resolve computes the final config from flags, env, file, and keychain. Priority for API key: flag > env > config file > keychain > (none). Priority for model: flag > env > config file > default. insecureStorage affects credential writes elsewhere, but reads always use the same precedence order.

func ResolveCircleCI added in v0.7.137 

func ResolveCircleCI(_ bool) (ResolvedConfig, error)

ResolveCircleCI returns only the CircleCI-related config needed by sidecar commands. It intentionally skips Anthropic and GitHub resolution so callers that only need CircleCI auth avoid unrelated keyring work.

type UserConfig 

type UserConfig struct {
	AnthropicAPIKey    string `json:"anthropicAPIKey,omitempty"`
	CircleCIToken      string `json:"circleCIToken,omitempty"`
	CircleCIUserID     string `json:"circleCIUserID,omitempty"`
	GitHubToken        string `json:"gitHubToken,omitempty"`
	Model              string `json:"model,omitempty"`
	UseSSHIdentityFile bool   `json:"useSSHIdentityFile,omitempty"`
	InstanceID         string `json:"instanceID,omitempty"`

	// Telemetry is the persisted telemetry preference: true enables it,
	// false disables it. nil means no preference has been set, in which
	// case telemetry defaults to enabled (it is opt-out).
	Telemetry *bool `json:"telemetry,omitempty"`

	// Notifications enables OS desktop notifications after validate completes.
	// false (zero value) means disabled; true means enabled (opt-in).
	Notifications bool `json:"notifications,omitempty"`

	// LegacyAPIKey reads the pre-rename "apiKey" field so existing users don't
	// silently lose their stored Anthropic key on upgrade. Migrated into
	// AnthropicAPIKey by Load and dropped on the next Save (omitempty).
	LegacyAPIKey string `json:"apiKey,omitempty"`
}

UserConfig is the on-disk JSON config.

func Load 

func Load() (UserConfig, error)

Load reads the config file. Returns empty config if not found.

type VCSConfig added in v0.7.2 

type VCSConfig struct {
	Org  string `json:"org,omitempty"`
	Repo string `json:"repo,omitempty"`
}

VCSConfig holds VCS configuration for the project.

type ValidationConfig added in v0.7.35
