This is the shell written by common lisp which was inspired by eshell on emacs. The purpose is it realizes we can use common lisp everywhere. Notice, you have to know this product is alpha status. You might lose important data or work by accidental crash!
Only sbcl. But if you reqeust, I will support it.
You need below libraries to use.
- GNU readline library
And you need below common lisp libraries. Maybe Quicklisp help to install.
- maxpc
- cl-fad
- alexandria
- cl-readline
- cl-ppcre
After clone this, execute below in the directory.
$ sbcl --load clsh.lisp --eval '(clsh:run)'When you run clsh, a prompt will appear and you can execute some commands and common lisp expression as you like.
~/work/:[COMMON-LISP-USER]>
~/work/:[COMMON-LISP-USER]> ls | sort
aaa bbb ...
~/work/:[COMMON-LISP-USER]> (describe 'func) | less
...
When executing single common lisp expression, it's executed same process like this. This means you can change environment variables or common lisp variable on the clsh process.
~/work/:[COMMON-LISP-USER]> (defvar *test-var* 1)
~/work/:[COMMON-LISP-USER]> (print *test-var*)
1
~/work/:[COMMON-LISP-USER]> (sb-posix:setenv "TEST" "ok" 1)
~/work/:[COMMON-LISP-USER]> (sb-posix:getenv "TEST")
"ok"
But if you use pipe function, clsh produce new process for executing.
~/work/:[COMMON-LISP-USER]> (defvar *test-var* 1) | cat
~/work/:[COMMON-LISP-USER]> (print *test-var*)
error!!
- editable command line.
- completion for lisp expressions or command & files.
- have a lot of bugs.
