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.
Lem supports other programming languages thanks to its built-in LSP client. You can choose between an Emacs and a Vim mode.
Other Lem features include:
- a project explorer tree view
- project-aware commands
- interactive grep and git interfaces
- multiple cursors
- tetris
- and more…
Lem 2.1 was released!
See our Lem 2.1 realease to download binaries for Windows, MacOS and Linux.
On mac, you need to run xattr -d com.apple.quarantine /Applications/lem.app.
See lem-project#635
Please refer to the following issue lem-project#628
- ncurses
- roswell (optional)
- SDL2 (optional)
- Linux
- MacOS
- Windows
Please install roswell at first.
After that, please follow the steps bellow.
1. install lem by roswell
$ ros follow-dependency=t install lem-project/lem
2. add the PATH
A0F1
in the initialization file(such as ~/.bashrc)
export PATH=$PATH:~/.roswell/bin
$ ros update lem
note: Perhaps this is not enough. If you get an error, try updating the submodule.
$ cd $(ros -e '(princ (ql:where-is-system :lem))')
$ git submodule update --init --recursive
$ ros follow-dependency=t install lem-project/lem
$ lem <filename.lisp>
You can watch the screencast on Youtube.
Please clone lem to a location where the path to asdf is accessible.
$ mkdir $HOME/common-lisp
$ cd $HOME/common-lisp
$ git clone --recursive https://github.com/lem-project/lem.git
You can start "lem" using the following command.
$ sbcl
* (ql:quickload :lem-ncurses)
* (lem:lem)
You can create the executable file of lem using the following command.
$ sbcl --eval '(ql:quickload :lem-ncurses)' --load build.lisp
Lem loads ~/.lem/init.lisp when starting up.
You can see an example here
fukamachi also published his init files on GitHub. https://github.com/fukamachi/.lem
- Pareto - A mode, complement to the Paredit. Makes Lisp code editing even more efficient!
