files are not tracked (no hunk in file)

[echaya]

What is the latest commit SHA in your installed vim-gitgutter? e801371 What vim/nvim version are you on? nvim 0.9.5

Hi there - hope you are well! I am switching from vscode to nvim now. And would appreciate any help!

This is my current gitgutter config:

let g:gitgutter_log=1
let g:gitgutter_git_executable = 'C:/Program Files/Git/bin/git.exe'
let s:log_file    = g:WorkDir.'gitgutter.log'
let g:gitgutter_async=0
let s:grep_available=0

When I do [-c] =>no hunk in file, also there is no sign in the singcolumn which is set toauto`. When ckecking the log file I see:

 38.228285 CursorHold Autocommands for "*"..function gitgutter#process_buffer[14]..<SNR>81_setup_path[3]..gitgutter#utility#set_repo_path[19]..gitgutter#utility#system[1]:

When try to execute cd /d "d:/Dropbox/neovim/config" && C:/Program Files/Git/bin/git.exe ls-files -v --error-unmatch --full-name -z -- .vimrc from the comand line, it produces

E344: Can't find directory "/d" in cdpath E472: Command failed

I thought I was on the right track and found a similar issue #174 and also tried set GIT_DISCOVERY_ACROSS_FILESYSTEM=1 on cmd bebefore running nvim. Got the same issue.

other things i have tried:

• run git init in the repo folder => same log msg
• create a test repo from c:\, I still got "cd /d xxxxxxxxxx" in the log file when performing 'git.exe ls-files -v --error-unmatch --full-name -z -- xxxx'
• try to launch nvim from powershell => same log msg
• try to use vim from C:/Program Files/Git/ folder => same log msg

Thanks a lot in advance!

[airblade]

Good idea to turn on logging, find the command that gitgutter was running, and try to run it directly in your shell. With this kind of problem, fixing it in the shell will tell us what the code needs to do differently.

Having said that, E344 and E472 are vim/nvim errors so it doesn't look like you ran it in the shell. Perhaps you could try this in your shell (and let me know which shell that is)?

cd /d "d:/Dropbox/neovim/config"

And inside nvim, what does :echo &shell produce?

[echaya]

Thanks for your prompt reply!

When I said I try to run "cd /d "d:/Dropbox/neovim/config" && C:/Program Files/Git/bin/git.exe ls-files -v --error-unmatch --full-name -z -- .vimrc" on command line, I actually mean cmdline within nvim

echo &shell returns me cmd.exe

cd /d "d:/Dropbox/neovim/config" works fine in CMD. or shall i run it in bash?

[echaya]

Now I run cd /d "d:/Dropbox/neovim/config" && c:/Program Files/Git/bin/git.exe ls-files -v --error-unmatch --full-name -z -- .vimrc in CMD, I got 'c:/program' is not recognized as an internal or external command, operable program or batch file.

[airblade]

Interesting that &shell is cmd.exe and cd /d d:/Dropbox/neovim/config" works fine in CMD – but fails inside nvim. I'll have to think about that.

The 'c:/program' is not recognized... is separate. I don't know how to specify the absolute path to Git on Windows. If you use plain git instead, does it work? I.e. cd /d "d:/Dropbox/neovim/config" && git ls-files -v --error-unmatch --full-name -z -- .vimrc

[echaya]

Seems to me the error is caused by the space between "Program" and "Files". On my home pc, I can try changing the install dir later and try but on my corp PC, it is not changable.

[airblade]

(By the way I'm planning to update gitgutter to use -C <dir> to avoid having to cd. But it would be good to get you up and running in the meantime.)

It returns me H .vimrc so it seems it is working fine (?).

[airblade]

OK, so don't set let g:gitgutter_git_executable = ... in your config.

[echaya]

I think it is working now - Thanks much!!!

[echaya]

Just curious, I feel the editor is bit "stuttering" => so I have turned they Async on, it stops working immediately.

I saw you asks another windows user to turn async off - may I check why?

[airblade]

When vim/nvim had only just introduced jobs, it was useful to turn off async to find out whether the problem at hand was caused by buggy async code or the core diffing stuff. These days there's no benefit to turning async off; in fact doing so will make your editor feel slower.

When you stay it stops working immediately, can you be more specific?

Also, what is your updatetime? You can find out with :echo &updatetime. Vim/nvim's default is 4000 (milliseconds) which is far too slow; you want something like 100.

my updatetime has been set to 100; When set let g:gitgutter_async=1 in .vimrc then source $MYVIMRC:

• signcolumn stops updating.
• quit nvim and reopen =>shows "no hunks in file"

[echaya]

check the async command produced in the log [async] cd /d "d:/Dropbox/neovim/config" && git ls-files -v --error-unmatch --full-name -z -- vim_config.vimrc which works fine in the cmd.

[airblade]

Please could you post more of the log? The command you pasted above is just the first one it runs, to find out whether a file is tracked by git. The diff stuff will be further down the log.

Also I just noticed that you are telling gitgutter that grep isn't available by setting a script variable (s:) instead of a global (g:). It needs to be a global.

I may have paste it from somewhere have update it to g: for grep. Below is the log just gen:

[airblade]

Thank you. And what does :echo b:gitgutter give?

[airblade]

By the way, I just pushed a change which avoids the cd /d step. Perhaps you could update your gitgutter, reproduce the problem, and tell me what :echo b:gitgutter shows.

{'path': -2, 'enable': 1, 'mapped': 1}

[airblade]

Thanks!

A path of -2 means either that gitgutter thinks the file is not tracked by git or that the git ls-files command error'ed for some other reason.

Given that signs appear when you turn off async, the problem must be running the git ls-files asynchronously – which is weird because that stuff hasn't caused any problems for years, as far as I know.

If you've updated gitgutter, the command should look like:

git -C "d:/Dropbox/neovim/config" ls-files -v --error-unmatch --full-name -z -- vim_config.vimrc

Please could you confirm that? And whether :echo has("win32") prints 1?

I confess I'm not really sure what the problem is. I'll keep thinking...

re :echo has("win32") prints 1 => yes and confirm now the command looks like git -C "d:/Dropbox/neovim/config" ls-files -v --error-unmatch --full-name -z -- repl_config.lua

Separately, I have managed to get gitsign-nvim works out of box. But since I have been using both vim and nvim depending on secnairo / enviroment, I'll also keep exploring :)

[echaya]

not much progress - I have updated my git to the latest versions the same issue persists.

[airblade]

Ok, to summarise:

• You're using Neovim on Windows.
• When you edit a file tracked by git, with let g:gitgutter_async = 0, the diff signs appear.
• When you edit a file tracked by git, without let g:gitgutter_async = 0, the diff signs don't appear and b:gitgutter.path is -2.
• Running git -C "d:/Dropbox/neovim/config" ls-files -v --error-unmatch --full-name -z -- repl_config.lua in your shell produces H repl_config.lua.
• Running :!git -C "d:/Dropbox/neovim/config" ls-files -v --error-unmatch --full-name -z -- repl_config.lua in Neovim produces H repl_config.lua.

Is that all correct?

[echaya]

All correct. Except now I run :echo b:gitgutter => 'path':'vim_config.vimrc'. It was in a different out format (only 3 keys) with path = -2.

[airblade]

The path format doesn't matter. b:gitgutter is a dictionary and path is one of its keys.

Anyway, if it says vim_config.vimrc instead of -2, that's progress. It means gitgutter has established that the file is tracked by git and can move on to diffing it.

But you're still not seeing diff signs? What does the log say now?

Okay. It is still -2 when doing async, returns the file_name in sync mode.

 endfunction

You can see the error message with :messages.

I think we are getting there. Finally there is some error msg, actually an array of "The syntax of the command is incorrect. ^M" ^M is a bad key from windows tho I'm not entirely sure how it is only happening in async mode: ref link

The ^M is irrelevant: it's just a stray line ending from the first line of the error message.

The syntax of the command is incorrect.

This is coming from cmd.exe but I don't know why.

This is a total guess:

If that doesn't work, you could try:

+    return has('nvim') ? [a:cmd] : 'cmd.exe /c '.a:cmd

return has('nvim') ? a:cmd : 'cmd.exe /c '.a:cmd

This line works! Really appreciate your help all along. Confirm the plug-in works on my vim and vim.

Feel free to close or lmk if you want me to test anything. Thanks again!
