Hello! I would like to anounce my library, guile-bash. With it, you can write your bash functions in Scheme, like this:
(use-modules (gnu bash))
(define-bash-function (dtach-start-emacs)
(unless (file-exists? "/tmp/emacs.dtach")
#$[dtach -n /tmp/emacs.dtach emacs]))
This strange #$ is reader macro. To give a try, you should download
it from https://github.com/kaction/guile-bash, like this:
$ git clone git://github.com/kaction/guile-bash
$ cd guile-bash
$ autoreconf -if
$ ./configure
$ make
$ make install
Make sure, that directory, where Guile modules are installed
are in GUILE_LOAD_PATH. Locate libguile-bash.so
and do in your bash
$ enable -f /path/to/libguile-bash.so scm
Now you can copy snippet above to a file and make
$ scm /some/file/with/code.scm
Now you should have `dtach-start-emacs` function availiable. To get
overview of what is availiable, see lisp/gnu/bash.scm Functions defined
with `define-ffi` and `define-public` are of interest.
About reader macro. To get variable value, write `#$HOME`, to set
(set! #$HOME).
#$[echo foo] is just eval
#$(echo foo) captures output.
If you use Debian GNU/Linux, debianization is ready on
https://github.com/kaction/deb-guile-bash
I am very interested in your opinions.
[please keep me in CC]
