type ApproveHandler ¶

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

ApproveHandler adds a reaction when a review is submitted with state "approved".

func NewApproveHandler(
	messages SlackMessages,
	mappings RepoMappings,
	slackClient SlackClient,
	logger *slog.Logger,
	emoji string,
	botEmoji string,
	detector *aireview.Detector,
) *ApproveHandler

func (h *ApproveHandler) Applicable(e Event) bool

func (h *ApproveHandler) Handle(ctx context.Context, e Event) error

type CloseHandler ¶

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

CloseHandler reacts to a PR being closed (merged or not). It updates the original Slack message with a [Merged]/[Closed] decoration and, if enabled, adds the corresponding reaction emoji.

func NewCloseHandler(
	messages SlackMessages,
	mappings RepoMappings,
	slackClient SlackClient,
	composer *slack.Composer,
	logger *slog.Logger,
	opts CloseOptions,
) *CloseHandler

func (h *CloseHandler) Applicable(e Event) bool

func (h *CloseHandler) Handle(ctx context.Context, e Event) error

type CloseOptions ¶

type CloseOptions struct {
	ReactionsEnabled bool
	MergedEmoji      string
	ClosedEmoji      string
}

CloseOptions tunes the CloseHandler. Reactions on close are toggleable because that's how the legacy PHP service exposed them.

type CommentedHandler ¶

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

CommentedHandler adds a reaction when a review is submitted or edited with state "commented".

func NewCommentedHandler(
	messages SlackMessages,
	mappings RepoMappings,
	slackClient SlackClient,
	logger *slog.Logger,
	emoji string,
	botEmoji string,
	detector *aireview.Detector,
) *CommentedHandler

func (h *CommentedHandler) Applicable(e Event) bool

func (h *CommentedHandler) Handle(ctx context.Context, e Event) error

type Dispatcher ¶

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

Dispatcher routes an Event to the first registered EventHandler whose Applicable returns true. Handlers are checked in the order they were registered. If no handler matches, Dispatch logs a Debug line and returns nil (no error) so the HTTP layer still responds 200 OK.

func NewDispatcher(logger *slog.Logger, handlers ...EventHandler) *Dispatcher

func (d *Dispatcher) Dispatch(ctx context.Context, e Event) error

type DraftHandler ¶

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

DraftHandler reacts to a PR being converted back to draft. It removes the Slack notification and forgets the message TS — the PR will be re-announced when it's marked ready_for_review again.

func NewDraftHandler(
	messages SlackMessages,
	mappings RepoMappings,
	slackClient SlackClient,
	logger *slog.Logger,
) *DraftHandler

func (h *DraftHandler) Applicable(e Event) bool

func (h *DraftHandler) Handle(ctx context.Context, e Event) error

type Event ¶

type Event struct {
	GitHubEvent string
	Action      string
	Repository  string

	PR PR

	// Review is non-nil only for pull_request_review events.
	Review *Review

	// PRComment is true for issue_comment events fired on a pull request (the
	// payload carried an issue.pull_request reference). False for comments on
	// plain issues, which CommentedHandler ignores.
	PRComment bool

	// Sender identifies the actor that fired the webhook. Type is "User"
	// for humans and "Bot" for GitHub Apps (Copilot, dependabot, …).
	Sender Sender
}

Event is the immutable record of an incoming pull-request-related webhook, detached from any HTTP payload type. Handlers receive Event and decide via Applicable whether they should run.

type EventHandler ¶

type EventHandler interface {
	Applicable(Event) bool
	Handle(context.Context, Event) error
}

EventHandler is implemented by each PR-lifecycle handler.

Applicable inspects an event and returns true if Handle should run. The dispatcher invokes the first handler whose Applicable returns true and skips the rest — handlers are mutually exclusive.

type OpenHandler ¶

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

OpenHandler reacts to a PR being opened (non-draft) or marked ready_for_review. It posts the first Slack message for the PR and records the message TS for later updates.

func NewOpenHandler(
	messages SlackMessages,
	mappings RepoMappings,
	slackClient SlackClient,
	composer *slack.Composer,
	logger *slog.Logger,
	dependabotFormat bool,
) *OpenHandler

func (h *OpenHandler) Applicable(e Event) bool

func (h *OpenHandler) Handle(ctx context.Context, e Event) error

type PR ¶

type PR struct {
	Number int
	Title  string
	URL    string
	Author string
	Merged bool
	Draft  bool
	// Body is the PR description, consulted by OpenHandler to tell a
	// Dependabot/Renovate security advisory from a routine bump.
	Body string
	// CreatedAt is the PR's open time (pull_request.created_at), rendered as a
	// localized date token in the Slack context line. Zero when the payload
	// omits it.
	CreatedAt time.Time
}

PR holds the PR fields needed across handlers and the message composer.

type RepoMappings ¶

type RepoMappings interface {
	Get(ctx context.Context, repository string) (store.RepoMapping, error)
}

RepoMappings reads the per-repository routing to a Slack channel.

type RequestChangeHandler ¶

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

RequestChangeHandler adds a reaction when a review is submitted with state "changes_requested".

func NewRequestChangeHandler(
	messages SlackMessages,
	mappings RepoMappings,
	slackClient SlackClient,
	logger *slog.Logger,
	emoji string,
	botEmoji string,
	detector *aireview.Detector,
) *RequestChangeHandler

func (h *RequestChangeHandler) Applicable(e Event) bool

func (h *RequestChangeHandler) Handle(ctx context.Context, e Event) error

type Review ¶

type Review struct {
	State string
}

Review carries the review state (approved | commented | changes_requested).

type Sender ¶ added in v0.5.0

type Sender struct {
	Login string
	Type  string
}

Sender identifies the actor on the webhook payload (the reviewer for review events, the PR author for `pull_request` opened events, etc.).

type SlackClient ¶

type SlackClient interface {
	PostMessage(ctx context.Context, channel string, msg slack.Message) (ts string, err error)
	UpdateMessage(ctx context.Context, channel, ts string, msg slack.Message) error
	DeleteMessage(ctx context.Context, channel, ts string) error
	AddReaction(ctx context.Context, channel, ts, name string) error
}

SlackClient is the subset of the slack package's client that handlers use.

type SlackMessages ¶

type SlackMessages interface {
	Save(ctx context.Context, m store.SlackMessage) error
	Get(ctx context.Context, repository string, prNumber int) (store.SlackMessage, error)
	Delete(ctx context.Context, repository string, prNumber int) error
}

SlackMessages reads and writes the per-PR Slack message TS record.
