Some limitations:

(require "fennelview") – i.e. requiring the library distributed with the
language – does not work. I spoke with members of freenode's #fennel and
a FENNEL_PATH could be added. In a future package definition,
wrap-program would set that variable. In the meantime, this can be
worked around:

         fennel --add-fennel-path "$(guix build fennel )/share/?.fnl"

No native readline support. I have decided not to package
https://luarocks.org/modules/peterbillam/readline as fennel 0.2.1's use
of readline does not give more functionality than rlwrap.

[bug#37411] [PATCH] gnu: Add fennel.

[Alex ter Weele]

[-- Attachment #1: Type: text/plain, Size: 385 bytes --]

fennel 0.3.0 just released. Below is an updated patch. The new release
includes FENNEL_PATH, which is now populated by the package
definition, so (require "fennelview") now works, addressing a
shortcoming of the previous patch. The new release also includes
completion via readline, which is not supported in this package
definition. For that reason, I would consider this patch WIP.

We can also add a comment for the lack of readline, and go ahead :-)

Look at its source code, I think it should be installed like this:

  fennel             -> ${out}/bin/fennel
  fennel.1           -> ${out}/share/man/man1/fennel.1
  fennel.lua         -> ${out}/share/lua/${lua-version}/fennel.lua
  fennelview.fnl     -> ${out}/share/fennel/fennelview.fnl

We may also pick some md files into ${out}/share/doc/fennel, and drop
other files...  What do you think?

I think its license should be 'expat', 'x11' has an extra paragraph
talking about "X Consortium":

Closing, as fennel@1.3.0 has been available for a good while already.
