Tool to format/indent scheme code

Tool to format/indent scheme code

[Huang, Ying]

Hi, All,

Sometimes, I want to check the contents of auto-generated scheme code in
store.  But the readability is not very good.  So I want to use a code
format/indent tool to help on this.  Do you know is there such tool in
Guix?  If no, any tool not in Guix?  Thanks in advance!

Best Regards,
Huang, Ying

In Guix' Git-repository, there is a file `etc/indent-code.el.in`. I
think, after running `./bootstrap`, it becomes `etc/indent-code.el` which
is then executable. I guess, it requires emacs being installed though.
You can then run `./etc/indent-code.el gnu/packages/foo.scm` or so.

I'm not sure if `indent-code.el` is only made for package definitions
(like gnu/packages/foo.scm) or if it also works for other Scheme code.

Maybe try it? Maybe somebody else knows? Maybe read the code?

I'm not sure if I was helpful.

In Emacs you can use "C-u M-x indent-pp-sexp" to pretty print a sexp
after the point.

BTW, if anyone is interested, Emacs-Guix uses 'indent-pp-sexp' to
pretty-print Shepherd config of a system generation, which can be shown
like this:

1. Run "M-x guix-system-generations"
2. Press "RET" on any generation to get more info
3. Press "Pretty print" button

Thanks a lot!  That is a useful tool.

This is a very good interface!
