[tarikgraba]

Adds the current edited file path to the linter search path.

As we are using a temporary file with verilator, we need to se the search path to the directory containing the original file.

@w0rp Any hint about the error that I am getting here and which I can't reproduce locally?

I left some comments here. I have pushed a commit which should fix another test which wasn't cleaning up its state properly.

Suggested change

	let g:fileDummy = tempname() . '.v'
	let g:file_dummy = tempname() . '.v'

Use snake_case for variable names.

[w0rp]

Use %s:h in the command instead, which is replaced with the absolute path to the directory of the file by ALE, and which can be replaced with a mapped filename if you're using something like Docker with the g:ale_filename_mappings option. See :help ale-command-format-strings and :help g:ale_filename_mappings for more information.

[w0rp]

See :help ale-dev for information on writing tests for linter definitions. Try to structure this more like other linter tests, such as test/command_callback/test_iverilog_command_callback.vader,

[tarikgraba]

I should have read the doc earlier...

Cheers! 🍻
