: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?
