How to set cwd on formatter?

[marcinjahn]

I'm struggling with providing a valid config for csharpier:

return {
  "stevearc/conform.nvim",
  optional = true,
  opts = {
    formatters_by_ft = {
      cs = { "csharpier" },
    },
    formatters = {
      csharpier = {
        cwd = require("conform.util").root_file(".csproj"),
        command = "dotnet csharpier",
        args = { "--write-stdout" },
      },
    },
  },
}

By default, conform uses csharpier from mason, but I'd rather want to use the version configured in a project that I'm working on, therefore I want to invoke dotnet csharpier from the directory where my project is located (.csproj).
What am I doing wrong?

:ConformInfo shows:

Formatters for this buffer:
LSP: roslyn
csharpier unavailable: Command not found

The built-in formatter for csharpier uses the command dotnet-csharpier

conform.nvim/lua/conform/formatters/csharpier.lua

Lines 7 to 9 in 62d5acc

	command = "dotnet-csharpier",
	args = { "--write-stdout" },
	stdin = true,

It's actually important that the command is a single word, the name of the executable to be run. If this is actually invoked via dotnet csharpier (I'm not familiar with this tool), then you should change the configuration to be

command = "dotnet",
args = { "csharpier", "--write-stdout" },

Right, it’s actually the same tool, the difference is that dotnet-csharpier invokes the version installed by mason(which for some reason is rather old), while ‚dotnet csharpier’ runs the version installed locally for a given project (via ‚dotnet tool’ utility).

to invoke the proper version of csharpier I need to invoke ‚dotnet tool’ from within the same directory where my .csproj is located.

Did you try my suggestion?

[marcinjahn]

It seems to work fine after applying your suggested config. I did not set any cwd. What is the command's directory by default?

[stevearc]

If the cwd is not specified in the formatter config, it will default to Neovim's cwd (:echo getcwd())
