[gentoo-lisp] vim with embedded racket

[Imran Rafique]

Gentoo-lispers,

Currently, vim support for embedded racket is disabled in
eclass/vim.eclass. I have patched this in my local overlay to add
support for both racket (and tcl). As dev-scheme/racket is itself not
part of the standard portage tree, I thought it might not make sense
to create a new bug to amend the standard vim.eclass. Would it be
better to just add the amended vim.eclass to the gentoo-lisp overlay
instead?

If so, then should I just send the patch to this list, or create a
bugzilla bug with some gentoo-lisp specific info?

Racket is on its way to main tree.

You can create a bug and have it depend on the bug about getting racket
in main tree (324161).

Will do. But there's one issue. I needed to replace /usr/bin/mzscheme
with a symlink to /usr/bin/racket.

Racket-5.1 (from this overlay) installs a /usr/bin/mzscheme binary in
addition to /usr/bin/racket. Seems like some useless leftover artifact
('racket' provides the repl, 'mzscheme' segfaults)

Vim-7.3 was released when racket was still plt-scheme, and it
specifically looked for the mzscheme binary. vim-7.3.049 updated the
scheme support to work with racket, but vim still looks for
'/usr/bin/mzscheme' and uses it (sure, thats an upstream issue, but
its what we have right now).

Replacing /usr/bin/mzscheme with a symlink to /usr/bin/racket sorted
that issue out, but this really needs to be something which the racket
ebuild itself resolves (whats that mzscheme binary for, anyway?)

I wasn't aware, but I just checked and with the live ebuild that I have
locally I indeed still get that file too and it does:

$ mzscheme
read failed to read all 31 bytes from file /usr/bin/mzscheme
Aborted

I'll talk to upstream about the mzscheme executable. How hard would it
be to fix vim to look for racket instead of mzscheme?

Yup, same here.

I just saw your mail on racket-dev. I was too lazy to do that - thanks :)

> How hard would it be to fix vim to look for racket instead of mzscheme?

Hmm, not sure. I had a quick look at patch 049 (which updated from plt-scheme
to racket) but didn't see anything obvious. There are other issues with how
racket is embedded. For example, the scheme snippet in configure, which detects
what racket's install prefix is, doesn't work. Its missing the '#lang scheme'
or a (module ...) form (I'll mention that to upstream).

Thats easily handled by my vim.eclass by bypassing this detection of racket's
prefix, by passing "--with-plthome=/usr/".

One quick way of fixing the mzscheme problem from our end (for now), would be
for the racket ebuild to just replace the mzscheme binary with a symlink to
racket, and install that. In keeping with the gentoo spirit of quick local
fixes while waiting for upstream to fix the problem :)
