vale linter not working with markdown files

[diegoholiveira]

I'm trying to setup vale as a linter to markdown file using this configuration:

let g:ale_linters = {'markdown': ['vale'], 'text': ['vale']}
let g:ale_markdown_vale_options = '--config=docs/vale/.vale.ini'
let g:ale_markdown_vale_input_file = '%s'

When I call :ALEInfo, vale is not being under the enabled linters neither the linter variables is displayed.

Current Filetype: markdown
Available Linters: ['alex', 'cspell', 'languagetool', 'markdownlint', 'mdl', 'proselint', 'redpen', 'remark_lint', 'textlint', 'vale', 'writegood']
   Linter Aliases:
'remark_lint' -> ['remark-lint']
'writegood' -> ['write-good']
  Enabled Linters: []
  Ignored Linters: []
 Suggested Fixers:
  'dprint' - Pluggable and configurable code formatting platform
  'pandoc' - Fix markdown files with pandoc.
  'prettier' - Apply prettier to a file.
  'remark-lint' - Fix markdown files with remark-lint
  'remove_trailing_lines' - Remove all blank lines at the end of a file.
  'textlint' - Fix text files with textlint --fix
  'trim_whitespace' - Remove all trailing whitespace characters at the end of every line.
 Linter Variables:
let g:ale_markdown_remark_lint_executable = 'remark'
let g:ale_markdown_remark_lint_options = ''
let g:ale_markdown_remark_lint_use_global = 0

note: If I call echo g:ale_markdown_vale_options, it display the value defined correctly.

Any ideas about what's happening?

This may be related to this issue: #3363, check specifically this comment: #3363 (comment)

I'm pretty sure it's not the same issue. Even when I disable my configs to vale, vim-ale doesn't enable it. And the command history is completely empty (it doesn't check if the executable exists).

Enabled Linters: []

You ALEInfo shows no linters are enabled. Make sure to set g:ale_linters variable properly:

let g:ale_linters = {
  \   'markdown': ['vale']
\}

That's the issue. I have this config in my vimrc, yet, vale is not displayed as an enabled linter.
