I'm trying to configure the vim Ale plugin to use Tidy to lint HTML code.
I added to my .vimrc file:
let g:ale_linters = {
\ 'css': ['csslint'],
\ 'html': ['tidy'],
\ 'javascript': ['eslint'],
\ 'php': [''],
\ 'python': ['flake8'],
\}
I got the linters working for CSS, JavaScript, and Python, but not HTML.
:ALEInfo outputs:
Current Filetype: html
Available Linters: ['alex', 'fecs', 'htmlhint', 'proselint', 'stylelint', 'tidy', 'writegood']
Linter Aliases: 'writegood' -> ['write-good']
Enabled Linters: ['tidy']
. . . at the end of the information . . .
Command History: (executable check - success) tidy
It looks like the Tidy linter is available and configured, but I can't get it to work. The html files seem to have no linting at all.
I am able to run Tidy successfully in the terminal:
> tidy test.html
line 1 column 1 - Warning: missing <!DOCTYPE> declaration
line 1 column 1 - Warning: plain text isn't allowed in <head> elements
line 1 column 2 - Warning: discarding unexpected <html>

line 1 column 1 - Warning: inserting missing 'title' element
line 3 column 7 - Warning: trimming empty <p>

How can I get Tidy to work with Ale in vim?
You also need to tell vim where to find the tidy executable, e.g., tidy on Linux, or tidy.exe on Windows.
In my case, I added this to my vimrc:
let g:ale_html_tidy_executable = "D://TidyHtml//tidy-5.6.0-vc14-64b//bin//tidy.exe"
In vim, to get Ale help for tidy: :h ale-html-tidy
