Functions ¶

func Supports ¶

func Supports(raw string) bool

Supports reports whether this adapter can handle the URL. Used by the provider registry to dispatch.

Types ¶

type Adapter ¶

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

Adapter fetches GitLab merge request data via the `glab` CLI.

func New ¶

func New(run provider.Runner) *Adapter

New constructs an Adapter. Passing nil uses provider.DefaultRunner and a default Preflight that calls exec.LookPath. Tests that need to substitute LookPath can use NewWithLookPath.

func NewWithLookPath ¶

func NewWithLookPath(run provider.Runner, lookPath func(string) (string, error)) *Adapter

NewWithLookPath constructs an Adapter with explicit run + lookPath injection so cross-package tests (e.g. internal/app/) can build a fully hermetic Adapter that needs neither real `glab` on PATH nor real network. Passing nil for either falls back to defaults (provider.DefaultRunner, exec.LookPath).

func (*Adapter) Fetch ¶

func (a *Adapter) Fetch(ctx context.Context, rawURL string) (*review.ReviewInput, error)

Fetch retrieves MR metadata and the unified diff via glab, then returns a normalized ReviewInput with Host=review.HostGitLab. The diff is parsed via internal/diff to surface classification errors early, before the model is invoked.

func (*Adapter) List ¶

func (a *Adapter) List(ctx context.Context, repo provider.RepoCoord) ([]provider.PRSummary, error)

List enumerates open MRs for the repo via `glab mr list`. Omitting `--opened` (deprecated as of glab v1.x) inherits the default "open" behavior without triggering the deprecation warning that glab writes to stdout, mixed with the JSON.

func (*Adapter) Preflight ¶

func (a *Adapter) Preflight(ctx context.Context) error

Preflight verifies glab is on PATH and authenticated before any fetch.

func (*Adapter) PreflightList ¶

func (a *Adapter) PreflightList(ctx context.Context) error

PreflightList verifies glab is authenticated before listing MRs.

func (*Adapter) Supports ¶

func (a *Adapter) Supports(rawURL string) bool

Supports reports whether the URL is a GitLab merge request URL.

type MergeRequestRef ¶

type MergeRequestRef struct {
	ProjectPath string
	Number      int
	URL         string // canonical: https://gitlab.com/<project-path>/-/merge_requests/<number>
	RepoURL     string // https://gitlab.com/<project-path>
}

MergeRequestRef identifies a GitLab merge request parsed from a URL. ProjectPath is the full URL-path namespace+project (e.g. "group/project" or "group/sub/project" for nested groups); the adapter splits it at the last slash to populate review.ReviewTarget.Owner/Repo. RepoURL is the project URL passed to `glab -R`.

func ParseURL ¶

func ParseURL(raw string) (*MergeRequestRef, error)

ParseURL extracts a MergeRequestRef from a GitLab merge request URL.

Accepts the canonical form and any sub-path under it (e.g. /diffs, /commits), query strings, and trailing slashes. Supports nested groups of any depth (gitlab.com/<group>/<sub>/.../<project>). Rejects URLs that are not MRs, not gitlab.com, or not HTTPS — self-hosted GitLab is a V1.x concern, not V1.

type Preflight ¶

type Preflight struct {
	Run      provider.Runner
	LookPath func(name string) (string, error)
}

Preflight verifies the runtime environment is ready to fetch GitLab MRs.

Per docs/architecture.md § Pre-Flight Checks, the model is never invoked when these fail; the user sees an actionable message instead of a stack trace from `os/exec`. Mirrors internal/provider/githubgh.Preflight; the only intentional divergence is the auth-failure error string ordering (actionable text first, %w wrap at the tail) so the contiguous acceptance-required substring is preserved without sacrificing errors.Is/Unwrap on the underlying transport error.

func NewPreflight ¶

func NewPreflight(run provider.Runner, lookPath func(string) (string, error)) *Preflight

NewPreflight builds a Preflight with sensible defaults. Tests inject fakes; production code calls NewPreflight(nil, nil).

func (*Preflight) Check ¶

func (p *Preflight) Check(ctx context.Context) error

Check runs `glab` binary presence and `glab auth status` in order. The first failure is surfaced with an actionable message; later checks are skipped.
