Struct SpawnConfig 

pub struct SpawnConfig {
    pub program: String,
    pub args: Vec<String>,
    pub cwd: Option<PathBuf>,
    pub env: Vec<(String, String)>,
    pub rows: u16,
    pub cols: u16,
    pub scrollback_lines: u32,
    pub paint_request: Option<Arc<Notify>>,
}

Inputs to spawn.

Fields

program: String

Path of the program to exec (e.g. /usr/bin/zsh, /bin/sh, cargo).

args: Vec<String>

Arguments for the program (excluding argv[0]).

cwd: Option<PathBuf>

Spawn working directory. None = inherit parent’s cwd.

env: Vec<(String, String)>

I5: extra environment variables to inject into the child, in addition to the inherited parent environment. Applied as CommandBuilder::env(k, v) per pair. Empty for an ordinary :terminal; the Claude Code IDE launch (:claude) injects CLAUDE_CODE_SSE_PORT + ENABLE_IDE_INTEGRATION so the spawned agent connects back to this editor’s IDE server.

rows: u16

Initial PTY size (rows, cols).

cols: u16

scrollback_lines: u32

T3 (2026-05-25): scrollback ring capacity in lines. 0 disables scrollback. Caller resolves the terminal.scrollback-lines typed option and passes the result here.

paint_request: Option<Arc<Notify>>

Optional repaint notifier — fired by the reader task after every published snapshot. Event-driven renderers (GPUI) need this wake to know terminal output has arrived; per-tick renderers (TUI) observe the publish on their next tick and don’t strictly need it. Wired by the host from Editor::paint_request so terminal output drives the same bridge the highlights worker uses.
