:Files and :FZF doesn't work. It just displays 0/0. Althought, all the rest of the commands work fine.

Need more detail on your environment (output of vim --version or :version, minimal vimrc, shell, which Windows OS, Cygwin?, did you upgrade both fzf repos to latest?, etc.)
Is running fzf (no args, no Vim plugin) by itself ok?

[SalahuddinAsh]

I'm using Windows 7
ConEmu terminal
I've just installed fzf yesterday.
When I run fzf alone in ConEmu, it is not recognized.1

vim --version output:
VIM - Vi IMproved 8.0 (2016 Sep 12, compiled Apr 23 2017 19:48:19)
MS-Windows 32 Bit Konsolen-Version

What do you mean with minimal vimrc?

[janlazo]

How did you install fzf? chocolatey? Is fzf in PATH?

Did you set TERM? Which shell do you use with ConEmu? bash?

For vim --version output, I need to know which (extra) patches are included.

minimal vimrc is the minimal config necessary to reproduce the problem. You can pass a custom vimrc to either vim or gvim from the command line with -u. For convenience, you can use vim-plug or Vim 8 packages to manipulate the runtimepath for the required plugins, included fzf and fzf.vim.

I installed fzf with choco install fzf
It was not in the path, but I added it now and it runs in cmd line. But it also shows 0/0 when run in the cmd
I did read someone talking about TERM but I don't know what is it and how should I set it.
In ConEmu I run cmd::Cmder shell.
The output of vim --version contains the following:

I have the following in my vimrc

" Set the runtime path to include Vundle and initialize
set rtp+=$VIM/vimfiles/bundle/Vundle.vim/

I expect the full output of vim --version to be similar to the following:

Is the Cmder task running cmd.exe or bash? I use ConEmu only, not the entire Cmder package.

[SalahuddinAsh]

It is running cmd.exe. But even when I switched it to run bash, fzf displayed 0/0.

[janlazo]

In junegunn/fzf@7f0caf0#diff-4425af3239f24c731114661daef5a811R62, fzf uses cmd.exe builtins for searching files so the command should work with the default PATH. Can you try it without fzf on a plain cmd.exe prompt? Copy/paste the command between the backticks into the prompt and run it.

[SalahuddinAsh]

Yes it works fine in the normal cmd line. Why doesn't it work in ConEmu?

[janlazo]

@SalahuddinAsh Can you try with just ConEmu, not Cmder? Pick a task to run cmd.exe and run the same command.

[SalahuddinAsh]

When I did that, it worked :)
Is there a way to get it work with Cmder::cmd?
I noticed it runs init.bat when I open a new Cmder::cmd

[janlazo]

cmderdev/cmder@56613b9 has set TERM=cygwin in init.bat so fzf assumes that it is running on bash and POSIX utils (ex. find, grep, diff, vim) are in PATH. It runs a different command, junegunn/fzf@bf0cb4b#diff-4425af3239f24c731114661daef5a811R57. fzf outputs 0/0 because sh.exe is not in PATH or the command executed by sh.exe failed

Question is why Cmder does this when sh or bash set TERM already if it is unset.

[SalahuddinAsh]

Commenting the line that sets TERM in init.bat made the ConEmu started in cmd.exe and fzf runs well. But this is not what I hope to have.

[janlazo]

Instead of changing init.bat, can you override the Cmder task? Is TERM=cygwin necessary for Cmder to work?

[SalahuddinAsh]

TERM=cygwin makes Cmder looks nicer. When I removed it, Cmder looks like the default Windows shell

[janlazo]

@SalahuddinAsh How does TERM=cygwin make Cmder look nicer? Does it use bash with a terminfo database?

[SalahuddinAsh]

@janlazo I'm sorry but I don't know much about these details.
But what I mean is, with TERM=cygwin, the text in the terminal is colorful and pretty. While when I removed it it was only white as in the default Windows cmd

[janlazo]

@SalahuddinAsh When using the Cmder task with TERM=cygwin, how do you check the value of TERM? echo %TERM% or echo $TERM?

[SalahuddinAsh]

@janlazo sorry for the late reply
echo $TERM prints $TERM
echo %TERM% prints cygwin

[janlazo]

@SalahuddinAsh I assume that Cmder task uses cmd.exe with no nested shells (ie. cmd.exe is only shell launched by Cmder through ConEmu). Can you give me a screenshot of Cmder with TERM=cygwin to get an idea of which package requires TERM to be set? bash and powershell do not support %VAR% syntax for environment variables and, IIRC, ConEmu does not depend on value of TERM.

ConEmu may modify PROMPT environment variable to add color to cmd.exe prompt. If the issue is the prompt, then I don't know how to solve it. I personally override it on ConEmu for a consistent prompt on Vim/Neovim's :terminal because Windows API supports up to 16 colors only prior to Windows 10.

[SalahuddinAsh]

I decided to move to nvim-qt and there :Files is working fine.

@janlazo Thanks for your concern

[vamolessa]

this is also an issue when trying to use neovim and fzf with alacritty on windows
neovim needs TERM set to display nice colors
fzf needs it to not be set for it to work

[jdehorty]

Spent several hours trying to get this to work without losing the nice formatting associated with set TERM=cygwin. The quick-fix for Cmder is to add the line set TERM= to the user_profile.cmd file (rather than the init.bat file).
