Common Lisp editor/IDE with high expansibility

Overview

Lem is the editor/IDE well-tuned for Common Lisp.

Build Status Backers on Open Collective Sponsors on Open Collective

After installing lem, you can start developing in Common Lisp at once.

You can skip over writing tidy settings or installing many plugins as you do on Emacs.

Terminal  

Requirement

Platform

Play with Lem in the Docker

You can try Lem by running it in a docker container:

docker run --rm -ti -v `pwd`:/app 40ants/lem:latest

Installation

Please install roswell at first.

Roswell Installation Guide

After that, please follow the steps bellow.

1. install lem by roswell
$ ros install lem-project/lem

2. add the PATH in the initialization file(such as ~/.bashrc)
export PATH=$PATH:~/.roswell/bin

Updating

$ ros update lem

Usage

$ lem <filename.lisp>

You can watch the screencast on Youtube.

Screencast

Configuration

Lem loads ~/.lem/init.lisp when starting up.

You can see an example here or here

fukamachi also published his init files on GitHub. https://github.com/fukamachi/.lem

Extensions and modes

  • Pareto - A mode, complement to the Paredit. Makes Lisp code editing even more efficient!

Electron version (Experiment)

Electron version is in the experimental stage.

If you try, please follow below steps.

$ node -v  # check if your nodejs is 8.9.3LTS+.
v8.9.3
$ npm -v
5.5.1
$ npm install -g cxxxr/lem   # install lem-electron
$ lem-electron               # Electron version will start

Electron  

Lem on platforms without SBCL thread support (e.g. raspberry pi3)

If installation fails due to bordeaux-threads, there is no thread provided by SBCL on your PC.
You need to use Clozure Common Lisp (CCL) instead of SBCL.

$ ros install ccl-bin
$ ros use ccl-bin
$ ros install cxxxr/lem

And also need to specify frontend to ncurses-ccl. You can launch lem as follows:

$ lem --frontend ncurses-ccl

  • Workaround for long line display v2

    Workaround for long line display v2

    折り返し時に画面の高さを超えるような長い行を表示したときに、 うまく表示や編集ができない件に対応しようとしてみたものです。

    #446 と違って、画面全体をスクロールできるようになりました。

    previous/next-line (C-p/C-n) - 対応済み previous/next-page (M-v/C-v) - 対応済み scroll-up/down (C-Up/Down) - 対応済み

    n 行まとめてスクロールする関数を作成したので、大分速くなりましたが、 それでも、折り返しの数が多くなると遅くなります (n=1000 とか) 。。。

    patch for MSYS2/MinGW-w64 (using PDCurses)

    こんにちは。日本語ですいません。

    Lem エディタを MSYS2/MinGW-w64 環境で動かすパッチを作成してみました。

    https://github.com/Hamayama/lem-mg-patch

    汎用性はありませんが、何かの参考になりましたら幸いです。

    (Common Lisp はあまり理解していません。 Scheme モードを実現したいと思っているのですが、先は長そうです。。。)

    P.S. tetris が分離されてしまい少し残念です。 デバッグ中はそれを動かすことが目標でした。 (新規ユーザのためには、こういう機能がデフォルトであるとうれしいと思いますが。。。)

    opening a LISP file or trying to load a (major) mode freezes editor

    Whenever i try to load a lisp file, or start a mode (slime or lisp-mode), the editor freezes completely and i can only close the terminal window.

    Working on Arch Linux /w XTerm, SBCL 1.4.16 ... any hints ?

  • lisp-compile-defun does not work for connection to CCL when there is active

    lisp-compile-defun does not work for connection to CCL when there is active "self connection"

    I'm using Lem from 7fb9c99d9f465efa31de4fcb1fb7615f937de541 commit (latest for today).

    The problem is that when I'm connecting from the LEM to a separate Lisp process, C-c C-c evals code in a wrong connection.

    NOTE: This problem is not possible to reproduce, if outer process is SBCL. Bug exists only on CCL.

    To reproduce this issue

    Start a separate CCL lisp process with a swank server

    (here I'm starting latest 1.12 build because 1.11 does not work on a recent OSX)

    rlwrap ./dx86cl64 -e '(load "/Users/art/quicklisp/setup.lisp")' -e '(ql:quickload :swank)'
    
    (swank:create-server :port 5009  :style :spawn :dont-close t)
    

    Start the Lem

    And connect to the 5009 port using a slime-connect command.

    Then call slime-self-connect.

    Switch back to ccl-bin

    Call lisp-connection-list, select the second line with CCL interpreter and hit Return (Enter).

      hostname  port  pid   name version                                    command
    * 127.0.0.1 51499 SELF  sbcl 1.5.8                                      NIL
      127.0.0.1 5009  52489 ccl  Version 1.12-dev (v1.12-dev.5) DarwinX8664 NIL
    

    Create a foo.lisp

    With following content:

    (defparameter *foo* "bar")
    

    Eval the line

    Hit C-c C-c on this line.

    Check the variable in the REPL

    Switch back to the REPL and enter:

    *foo*
    

    You should receive a

    Unbound variable: *FOO*

  • fix M-x crash problem for frontend based on electron.

    fix M-x crash problem for frontend based on electron.

    Tested on macOS™. On the os, key sequence Alt-option + X generates M-≈ but not M-x by default. that causes lem-rpc crashed. There're few resorts we can take to resolve this issue on the application layer, or accurately a browser context. Nevertheless remapping the code to the value is a way.

  • Ctrl-k(kill line)の動作が遅い

    Ctrl-k(kill line)の動作が遅い

    こんにちは。 以下の環境でのlemのCtrl-Kを押した時の行が削除されるまでの時間が他のエディタに比べて遅いです。

    | OS | macOS | | -|-| | Verison | 010a480 |

    Cursesの問題かもしれませんが、その場合はEmacsの同様のコマンドやVimのdd等も遅くなるはずなので、Cursesの問題ではなくlemの方に問題があると判断しました。

    よろしくお願いいたします。

  • Improper resizing of Electron window with tiling window manager

    Improper resizing of Electron window with tiling window manager

    When I load lem-electron while using a tiling window manager, the lem-electron window will constantly attempt to resize itself. I suspect that the problem arises from lem-electron being unable to display fractional columns or rows (and not having margins when the chosen window size does not correspond to an exact column/row size).

    The constant resizing results in flashing visual artifacts that make the electron frontend unusable, unless I disable the tiling window manager.

    lem using ncurses in a terminal does not suffer from the same issue.

Releases(v1.9.2)
  • v1.9.2(Dec 3, 2021)

    • When trying to open files that could not be recognized as text files, abort and show message.
    • define-command changed
      • Users have to change their own lem configuration to fit for this version. define-command arg-descriptor doesn’t have compatibility with old versions.
      • Generate class when defining commands. advice-classes can be added because of it.
      • When you redefine the same name command with a different form, an error will occur.
    • syntax-highlight for lisp-mode changed. Now you can get proper highlighting for define-xxxx . Before this version, it was only highlighted until define-.
    • slime command becomes non-blocking. While connecting swank-server animation on mode-line would be shown.
    • Fix if a key is already bound; attempting to override that binding produces an error. (by Gordon Brown )
    • Add C-M-y (kill-around-form)
    • Rename editor variable truncate-lines to line-wrap.
    • Transparency can be dealt with by overlay. When you mark region, you can see the foreground attribute still be seen. You can see the difference when you use directory-mode’s underlined line.
    • Optimize for less redrawing.
    • Refactoring and adding tests and a lot of fix bugs.

    • バイナリファイルを開こうとしたときに失敗した場合メッセージを出してabortするようにした。
    • define-commandの変更
      • arg-descriptorの変更によって過去との互換性が無くなった。
      • classを定義するようになった。結果としてadvice-classesを追加できるようになった(selection-mode/selection-mode.lisp参照)
      • 同名のコマンドを再定義するときに内容が違っているとリスタートエラーを出すようになった。
    • lisp-modeのシンタックスハイライトでdefine-xxxxのdefine-までしか色がつかなかかったのを修正。
    • slimeコマンド中にブロックしないようになった。ロード中にモードラインにアニメーションが表示されるようになった。
    • define-keyで単一のキーの定義の後に単一キーで始まる複数キー定義をした際にエラーが出ていたのを修正し上書きする挙動に直した。
    • C-M-y (kill-around-form) を追加
    • エディタ変数truncate-linesをline-wrapに変更
    • オーバーレイを透過させるようになった。(範囲選択をした際や、directory-modeの下線のバックグラウンドカラーが維持されるようになった。)
    • 再描画の最適化
    • 沢山のリファクタリングとテストの追加そしてバグの修正。
