Version 0.2.1 of package Codex-Ide has just been released in NonGNU ELPA. You can now find it in M-x list-packages RET.
Codex-Ide describes itself as: =========================== Run Codex CLI in a terminal =========================== More at https://elpa.nongnu.org/nongnu/codex-ide.html ## Summary: 1 Codex IDE integration for Emacs and Neomacs ═════════════════════════════════════════════ 1.1 About ───────── ⁃ [codex] native integration for Emacs via [Eat] by default ⁃ Run Codex in a project-scoped terminal buffer. ⁃ Optionally use [vterm] when it is installed separately. ⁃ Resume, switch, cycle, and stop multiple live Codex sessions. ⁃ Optional IDE context provider and local Emacs MCP tools bridge. ⁃ Requires GNU Emacs 29.1 or newer, or Neomacs with the native APIs below. [codex] <https://github.com/openai/codex> [Eat] <https://codeberg.org/akib/emacs-eat> [vterm] <https://github.com/akermu/emacs-libvterm> 1.2 Commands ──────────── ## Recent NEWS: ━━━━━━━━━━━━━━━━━━━━━━ EMACS-CODEX-IDE NEWS ━━━━━━━━━━━━━━━━━━━━━━ 1 Version 0.2.1 (2026-10-11) ════════════════════════════ • Require Eat again. It is the GNU Emacs default backend, so a fresh install no longer fails on the first `codex-ide' until Eat is added by hand. Eat is still loaded only when an Eat session starts, so Neomacs sessions on `neo-term' never load it. 2 Version 0.2.0 (2026-10-11) ════════════════════════════ • Incompatible changes: • `codex-ide-list-sessions' opens a session list buffer; completion moved to `codex-ide-switch-session'. • Menu `q' only closes the menu; kill a session with `k'. • Failed sessions keep their buffer by default (`codex-ide-kill-buffer-on-exit'). • GNU HTTP MCP requires a per-session token, so persistent GNU installation is refused. Remove an old persistent `emacs_tools' entry from the Codex configuration. • Give native Neomacs sessions `TERM=xterm-256color' and `COLORTERM=truecolor' instead of the frame's `TERM=dumb', so Codex keeps its full colour styling. • Resume saved conversations in new live sessions, preserving existing sessions. Keep the picker newest first, annotate IDs with date and directory, cache rollout metadata, and resume global fallback choices in their recorded cwd while routing project commands through the normalized ownership root. • Keep failed terminal output with an exit notice. Customize `codex-ide-kill-buffer-on-exit' to retain all buffers or close all exits. • Confirm interactive session stops and continue after optional context startup failures. Show the session label and backend in the mode line. • Use the configured display policy for session switching and panels, scope window lookup to the selected frame, and restore splits when hiding. • Send literal Ctrl+J for newlines, retain minibuffer prompt history, and display source attachments without selecting the session, using project-relative paths. • Cache CLI availability, failures and version output by executable path. • Make `codex-ide-list-sessions' a native tabulated session list with switching, confirmed kill, labels, refresh, and popup help. Its former completion behavior is now `codex-ide-switch-session'. • Rename project completion to `codex-ide-switch-project-session' and cycling to `codex-ide-cycle-session'. Keep the former `codex-ide-list-project-sessions' and `codex-ide-toggle' as obsolete aliases. • Keep popup `q' for exit/back; move session kill to `k' and MCP stop to `K'. Organize the menu by goal in two columns, add Context actions, use `l=/=L' for project/all session completion, and dim unavailable actions. • Show current backend, approval, and sandbox overrides in configuration. Retain explicit terminal backend choices across restarts. Save other nondefault options, remove saved overrides restored to defaults, and allow a bare CLI executable name. • Authenticate GNU HTTP MCP with per-session environment bearer tokens and infer review owners from authenticated sessions. Refuse persistent GNU HTTP installation; native Neomacs stdio registration is unchanged. Revoke session tokens at process exit even when terminal output is retained. • Add `codex-ide-mcp-disabled-tools' and allow `C-g' to interrupt tool calls. • Bound job output in hidden buffers. Read effective native MCP configuration once on each start so inherited configuration changes are respected. • Accelerate MCP JSON with native functions where available. Review results now carry their complete data in `structuredContent' and a short text status, avoiding a second encoding of large accepted edits. • Capture execution backtraces at the error site when supported, require open buffers for context paths, and close excess HTTP clients cleanly. • Queue MCP diff proposals until `codex-ide-diff-show' is invoked, with a pending mode-line indicator and notification that never changes windows. • Show project-relative review targets and current accept, reject, and help keys. Select proposal major modes with core syntax and fontification setup, without user mode hooks or file-local settings. … …
