Overview

Package prefix caches the tmux prefix key and its binding table.

Frontend can't invoke "C-b" directly via send-keys (it would just be sent as a key press to the active program), so the server runs an FSM:

  1. user sends prefix key → enter "prefix waiting" state
  2. next key → look up binding in this cache → run the bound command

Mirrors stations/tmux-webui/server.py:383-463.

Types

type Cache 

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

Cache lazily fetches the prefix key + bindings on first access. Safe for concurrent use; subsequent calls return the cached value.

func New 

func New(c *tmuxctl.Client) *Cache

func (*Cache) Bindings 

func (c *Cache) Bindings(ctx context.Context) map[string]string

Bindings returns key→tmux-command from `tmux list-keys -T prefix`. Empty map on error (callers should fall back to sending the raw key).

func (*Cache) Key 

func (c *Cache) Key(ctx context.Context) string

Key returns the global tmux prefix key (e.g., "C-b"). Falls back to "C-b" on any tmux error to keep the FSM functional even if the local tmux binary is missing or misbehaving.

func (*Cache) Lookup 

func (c *Cache) Lookup(ctx context.Context, keyCombo string) string

Lookup returns the bound tmux command for keyCombo. Empty string means no binding — caller should send the key as a raw input.
