~/.lem/init.lisp when starting up.
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
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
You can launch lem as follows:
$ lem --frontend ncurses-ccl
