Replaces the whole file with time status.

[FormalSnake]

I am using nvim format-on-save, and using this line I got it to execute the dotnet csharpier command:

cs = formatters.shell({ cmd = { "dotnet-csharpier", "." } }),

and it replaces the whole file with:
Formatted 5 files in 98ms.

I am not sure if this is a plugin issue or a csharpier problem

I'm not familiar with nvim format-on-save, but the command dotnet-csharpier . will format files in place in the location it is run from.

If you run dotnet-csharpier [pathToFile] --write-stdout it would read the saved file and write the formatted results back to std out, which may work.

It is also possible to pipe input to dotnet-csharpier --write-stdout, which will also write the formatted results of the piped file back to std out.

You may also want to look into https://github.com/sbdchd/neoformat which has support for csharpier. The fact that it supports csharpier is the extent of my knowledge though, I don't know how it compares to nvim format-on-save.

So, after testing the command it does not seem to output the file, even in the normal console.

[FormalSnake]

it only outputs when I make a change to the file

[FormalSnake]

but then the file just becomes empty when I save with no change

Ah, it seems that there is a bug related to the caching that is done to speed up formatting when combined with --write-stdout. I created #973 to address that.

For now if you run with --write-stdout --no-cache then the file will be returned. However if there is a compilation error, then an error is written on stderror and nothing is written on stdout. I believe it also returns an exitcode of 1.

[FormalSnake]

Yep, that did work. But can there be an argument to not output errors and just the file without formatting?
cs = formatters.shell({ cmd = { "dotnet-csharpier", "%", "--write-stdout", "--no-cache" } }),

[belav]

There isn't a way to get back the file, but --loglevel none would prevent the error from returning. Which probably gets you back to ending up with an empty file.

Maybe your best bet for now is to wire up some basic logic that checks the exit code of csharpier, either returning the output of csharpier, or the contents of the file. Put that into a powershell or bash script, and then call that script from your formatter.

I will try that out, I should probably open an issue in the neovim plugin aswel.
