Can't convince null-ls prettierd is executable

[ghost]

I have npm installed prettier/prettierd in a markdown file project, and the linters work from the command line:

./node_modules/.bin/prettier test.md and cat test.md | ./node_modules/.bin/prettierd test.md both work. I've also tried adding the path to .bin to my system path, and both commands work without the path to the program.

However, null-ls keeps telling me the program is not executable when I run the formatter.

Config:

local null_ls = require('null-ls')

local sources = {
    null_ls.builtins.formatting.prettier.with({
       command = 'C:/Users/me/Documents/project/node_modules/.bin/prettierd'
 }

null_ls.setup({ log_level = 'debug', sources = sources })

I've also tried C:\\Users\\me . . . and C:\\\\Users\\\\me . . . style paths in the command option

I'm on Windows 10 with MINGW/MSYS executables in path.

I don't know anything about Windows, but based on the discussion in #1341, I understand that Windows uses a .cmd wrapper script. Does adding that to the command make a difference?

I saw the cmd wrapper approach on LSPconfig too, but I'm not finding it necessary for some reason.

But . . . the issue you linked did help--specifically #1341 (comment).

Unlike Linux, Windows determine a file is executable or not, is rely on file's extension. when file's extension changes, the file will not be executable.

I rename prettier.cmd to prettier.cmd3, and it can not be executed.

I changed the command to prettierd.cmd instead of prettier and it works now.

Is there a way to combine prefer_local and command? If I use prefer_local it seems null-ls looks for prettierd, but I'd like it to look for prettierd.cmd at the local directory.

Edit: Seems like using the two together just works! I was expecting command to override the local path, but it doesn't.
