gash-utils & fzf conflict

Hello,

Gash-utils causes fzf to fail.

After installing gash-utils, attempting `bash5.0$ fzf` produces:

```

[Command failed: set -o pipefail; command find -L . -mindepth 1 \( -path '*/\.*' -o -fstype 'sysfs' -o -fstype 'devfs' -o -fstype 'devtmpfs' -o -fstype 'proc' \) -prune -o -type f -print -o -type l -print 2> /dev/null | cut -b3-]

```

Uninstalling gash-utils removes the problem.

Best,

Blake

Seems like 'coreutils' (or 'coreutils-minimal'?) should be added to the

wrap-program & inputs in the package definition of 'fzf' (untested),

and bin/fzf should be wrapped as well.

Or maybe it's not the fzf that is problematic, but the bash

completions.

Greetings,

Maxime.

Blake,

This isn't ‘really’ a bug: fzf invokes whichever find(1)

executable happens to be in $PATH at run time, and reasonably

expects it to support the POSIX ‘-L’ option.

It also willfully tries to hide any useful error messages:

…maybe that's what makes Rust so safe?

gash-utils doesn't implement find -L, so failure is to be

expected. As you discovered the fix is as simple as uninstalling

gash-utils, and possibly using it in a Guix environment if you

really need it.

I don't think installing gash-utils globally into your main

profile is a good idea!

Since find(1) is such a key requirement of fzf, it makes sense to

treat it as a fixed input in this case and keep a reference to

findutils' in a wrapper.

Done in commit 9bac41c2b8e7be5ab713402591ceeb32c635c214.

Thanks!

Hi Blake and Tobias,

Definitely not! Gash-Utils is very much pre-alpha software, and I don’t

really intend for those utilities to be useful beyond bootstrapping

their fully-featured GNU cousins. Ideally there would be a

bootstrapping version of Gash-Utils that installs the utilities, and a

regular version that just has Scheme interfaces. To date, it has felt a

little premature to bother with that.

However, if you find the Scheme interfaces from Gash-Utils useful, I’m

happy to make accommodations. Right now, I think that Guilers either

write their own utilities like ‘find-files’ or they copy them out of

Guix’s ‘(guix build utils)’ module (I tend to do the latter). It would

be nice if Gash-Utils could cover this use case and be a bit like

Python’s ‘shutil’, allowing a smoother transition from shell scripting

skills to Guile scripting skills.
