Msys vim's executable() can't find programs despite them being add in the PATH

[ykhan21]

Steps to reproduce

1. On Windows, install msys (https://www.msys2.org/).
2. Install the scoop package manager (https://scoop.sh/) on Windows (not in an msys environment).
3. Install fzf with scoop (scoop install fzf) on Windows (not in an msys environment).
4. Open an msys ucrt terminal by typing ucrt in the Windows search bar. This will start bash.
5. Use pacman to upgrade vim.
6. Open another terminal with regular Windows cmd.exe.
7. Observer that fzf is found in cmd but not bash.
8. Add ~/scoop/shims to the PATH variable in ~/.bashrc (in the ucrt terminal). Source the ~/.bashrc file in bash.
9. Observe that you can now find fzf in bash. which fzf should return /c/Users/KhanY_z23jg7i/scoop/shims/fzf.
10. Start vim in bash.
11. Run :echo executable('fzf'). Observer that vim can't find fzf despite it being added to the path.
12. Add `set rtp+=~/scoop/shims' to the .vimrc and source it.
13. Observe that :echo executable('fzf') still can't find fzf.

Expected behaviour

Vim in msys should be able to find executables present in the PATH environment variable or in the vim runtimepath.

This is strange because Git Bash's vim can find fzf from the PATH variable (without it being added to the runtimepath).

Git Bash's (https://git-scm.com/download/win) vim version: 9.1.264
Msys's vim version: 9.1.380

Version of Vim

Fzf can be found in Vim in Git Bash so that I wonder what the difference to MSYS2 vim is.
Confusingly, at the end Git Bash's vim is mentioned, but MSYS(2) has to be installed.
Would it not help to have the outputs of %PATH% respectively $PATH, in particular in Vim?

Or does this imply that $PATH in Vim in MSYS(2) was checked to be the same as in Vim in Git Bash?

[Konfekt]

There's a some conversion to include%PATH% into $PATH, so maybe that's where the difference lies. Git Bash Vim is a more common setup than MSYS Vim, so perhaps some path in %PATH% is amiss?

Git Bash (GB) doesn't need to be installed. I was just noting that Git Bash's vim is able to pick up fzf because GB's vim, which seems to be a discrepancy as MSYS's vim and GB's vim are both compiled under MSYS.

GB's $PATH will inherit from Window's %PATH%. MSYS's $PATH will not.

When I installed scoop on Windows, scoop added the scoop\shims directory to the Windows %PATH%, causing it to automatically appear in the Git Bash $PATH.

However, I have added the ~/scoop/shims scoop directory to the $PATH in the ~/.bashrc file by adding the line export PATH=$PATH:"~/scoop/shims".

This worked to make MSYS's bash aware of fzf, but not MSYS's vim.

:echo %PATH% in vim returns:

E15: Invalid expression: "%PATH%"

:echo $PATH in MSYS's vim:

[Konfekt]

You might have better chances with export PATH=$PATH:"$USERPROFILE/scoop/shims" in ~/.bashrc (or $HOME).
If neither $USERPROFILE, nor $HOME, then /c/Users/username.
Maybe let $BASH_ENV = $HOME.'/.bashrc is needed as well.
By the way, I thought rather ~/.bash_profile than ~/.bashrc to be read by Git Bash MSYS2, so maybe also MSYS2 itself?

[ykhan21]

When I add the export ~/.bashrc, MSYS picks it up fine as evidenced by which fzf in MSYS. However, MSYS vim's executable() function does not pick it up.

I will try the other PATH recommendations and report back later.

[benknoble]

It looks like tilde-expansion was not performed in the broken case; compare ~/scoops/shim with c:/users/username/scoops/shim

[Konfekt]

Yes, in terms of robustness: /c/Users/username > $HOME/USERPROFILE > ~/, from experience.

[ykhan21]

Thanks. /c/users/username, $HOME, and $USERPROFILE worked as opposed to the ~.

So I guess this is not a Vim issue but rather a bash/msys particularity. Let's close it then.
