Overview

Package ipc provides inter-process communication between the Forge daemon and CLI/TUI clients via platform-native mechanisms (named pipe on Windows, Unix domain socket on Linux/macOS).

Protocol: newline-delimited JSON messages.

Server side (daemon): 

svr := ipc.NewServer()
svr.OnCommand(func(cmd Command) Response { ... })
svr.Start(ctx)

Client side (CLI/TUI): 

client := ipc.NewClient()
resp, err := client.Send(Command{Type: "status"})
events := client.Subscribe(ctx) // stream events

Types

type ClarificationPayload

}

ClarificationPayload is the payload for "set_clarification" / "clear_clarification" commands.

type Client 

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

func (*Client) Send 

func (c *Client) Send(cmd Command) (*Response, error)

Send sends a command and waits for a response.

func (*Client) Subscribe 

func (c *Client) Subscribe(ctx context.Context) <-chan Event

Subscribe returns a channel that receives events from the daemon. The channel is closed when ctx is cancelled or the connection drops.

type CloseBeadPayload 

type CloseBeadPayload struct {

	Anvil  string `json:"anvil"`
}

CloseBeadPayload is the payload for a "close_bead" command that closes a bead via bd close.

type Command 

type Command struct {
	Type    string          `json:"type"`    // "status", "kill_worker", "refresh", "queue", "run_bead", "set_clarification", "clear_clarification"
	Payload json.RawMessage `json:"payload"` // Type-specific data
}

Command is a message sent from a client to the daemon.

type CommandHandler

CommandHandler is called by the server for each incoming command.

type CrucibleStatusItem 

type CrucibleStatusItem struct {
	ParentID          string `json:"parent_id"`

type DismissBeadPayload 

type DismissBeadPayload struct {
	BeadID string `json:"bead_id"`
	Anvil  string `json:"anvil"`
	PRID   int    `json:"pr_id,omitempty"`
}

DismissBeadPayload is the payload for a "dismiss_bead" command. Removes the bead from the Needs Attention list. When PRID > 0, the dismiss targets an exhausted PR (setting status to closed) rather than the retries table.

type Event 

type Event struct {
	Type      string          `json:"type"`
	Timestamp time.Time       `json:"timestamp"`
	Data      json.RawMessage `json:"data"`
}

type KillWorkerPayload 

type KillWorkerPayload struct {
	WorkerID string `json:"worker_id"`
	PID      int    `json:"pid"`
}

KillWorkerPayload is the payload for a "kill_worker" command.

type MergePRPayload 

type MergePRPayload struct {
	PRID     int    `json:"pr_id"`
	PRNumber int    `json:"pr_number"`
	Anvil    string `json:"anvil"`
}

MergePRPayload is the payload for a "merge_pr" command. Triggers a squash merge (or configured strategy) of a ready-to-merge PR.

type Response 

type Response struct {
	Type    string          `json:"type"`    // "ok", "error", "status", "event"
	Payload json.RawMessage `json:"payload"` // Type-specific data
}

Response is a message sent from the daemon to a client.

type RetryBeadPayload 

type RetryBeadPayload struct {
	BeadID string `json:"bead_id"`
	Anvil  string `json:"anvil"`
	PRID   int    `json:"pr_id,omitempty"`
}

RetryBeadPayload is the payload for a "retry_bead" command. Clears needs_human flag and resets retry count so the bead re-enters the queue. When PRID > 0, the retry targets an exhausted PR (resetting fix counters and status back to open) rather than the retries table.

type RunBeadPayload 

type RunBeadPayload struct {
	BeadID string `json:"bead_id"`
	Anvil  string `json:"anvil"` // Optional: narrows search if multiple anvils have same bead ID
}

RunBeadPayload is the payload for a "run_bead" command.

	// dispatch remains allowed while this flag is true.

	// CopilotPremiumRequests is the weighted count of Copilot premium requests used today.
	CopilotPremiumRequests float64 `json:"copilot_premium_requests,omitempty"`
	// CopilotRequestLimit is the configured daily limit (0 = no limit).
	CopilotRequestLimit int `json:"copilot_request_limit,omitempty"`
	// CopilotLimitReached is true when the copilot daily request limit has been reached.
	CopilotLimitReached bool `json:"copilot_limit_reached,omitempty"`

StatusPayload is the response for a "status" command.

type TagBeadPayload

	Anvil  string `json:"anvil"`
