Support for different linter command

[rkshthrmsh]

Currently, the configuration only has an option to enable or disable the linter:

# linter can be enabled (true) or disabled (false)
[option]
linter = true

Is there support for passing a different linter command to svls? For example, maximum line length checks are enabled using a shell wrapper to svlint: https://github.com/dalance/svlint/blob/master/MANUAL.md#test-each-file-for-excessively-long-lines. How can this feature be used from svls?

This isn't exactly part of svls, but you can do something like this.

I am using Vim with the vim-lsp plugin, so this is normally in my ~/.vimrc:

if executable('svls')
    au User lsp_setup call lsp#register_server({
        \ 'name': 'svls',
        \ 'cmd': {server_info->['svls']},
        \ 'whitelist': ['systemverilog'],
        \ })
endif

When I want to use a different command, like svls --debug or with the SVLINT_CONFIG environment variable, I create a small wrapper script.

First, let's call it /path/to/script/svls-alt:

#!/usr/bin/env bash
SVLINT_CONFIG="/path/to/config/alt.toml" svls --debug $*

Second, I set the executable flag and add it to the PATH in my terminal:

$ chmod +x /path/to/script/svls-alt
$ export PATH="/path/to/script:$PATH"

Third, I update my ~/.vimrc to call the script instead of the svls binary:

if executable('svls-alt')
    au User lsp_setup call lsp#register_server({
        \ 'name': 'svls-alt',
        \ 'cmd': {server_info->['svls-alt']},
        \ 'whitelist': ['systemverilog'],
        \ })
endif

Now, if I want to change the command (or run additional commands), then I can edit /path/to/script/svls-alt.
