Function launch_editor

crates/chat-cli/src/util/editor.rs:17–41

Launch the user's preferred editor with the given file path. This function properly parses the EDITOR environment variable to handle editors that require arguments (e.g., "emacsclient -nw"). # Arguments `file_path` - Path to the file to open in the editor # Returns `Ok(())` if the editor was launched successfully and exited with success `Err` if the editor failed to launch or exited with an err

(file_path: &Path)

/// * `Ok(())` if the editor was launched successfully and exited with success
/// * `Err` if the editor failed to launch or exited with an error
pub fn launch_editor(file_path: &Path) -> eyre::Result<()> {
    let editor_cmd = get_editor();

    // Parse the editor command to handle arguments
    let mut parts = shlex::split(&editor_cmd).ok_or_else(|| eyre::eyre!("Failed to parse EDITOR command"))?;

    if parts.is_empty() {
        eyre::bail!("EDITOR environment variable is empty");
    }

    let editor_bin = parts.remove(0);

    let mut cmd = Command::new(editor_bin);
    for arg in parts {
        cmd.arg(arg);
    }

    let status = cmd.arg(file_path).status()?;

    if !status.success() {
        eyre::bail!("Editor process did not exit with success");
    }

    Ok(())
