[htmllint] found 256 errors out of 102 files

but it seems i'm the only one getting these? #22534 (comment)

this is on my local branch, which is sync'd and rebased with the latest v4-dev here

i submitted #22500 to fix the above linting errors, but now i'm more fundamentally wondering why others may not be getting these linting errors. thoughts? /cc @Johann-S

[Johann-S]

You're not alone @patrickhlauke when I ran npm test just like you I have same errors and I'm on Windows 10 too

[patrickhlauke]

Ah ok...phew. In which case I'm hoping @mdo can have a look at #22500 soon, as at the moment I can't fix things/submit substantive PRs while trying to use the new build system... (unless I run some local modification on my branches, which I'd like to avoid...)

[peterblazejewicz]

FYI on Windows only? - current branch passes on my OS X [htmllint] found 0 errors out of 21 files

[wolfy1339]

Current v4-dev passes on Ubuntu 16.04.2, so this confirms that this is a Windows only problem

[patrickhlauke]

so how can this be a windows only issue? is some tool before the lint step not generating the same output? is the linting not happening the same way? because the errors the linter is reporting are indeed valid errors, and i'm surprised they've not been picked up before...

[patrickhlauke]

@peterblazejewicz [htmllint] found 0 errors out of 21 files how come it's only linting 21 files? i'm sure the full docs comprise more than just 21 html files... [edit: and note in my case, it found errors in 102 files]

[wolfy1339]

Could it be possible that Jekyll is giving different outputs between Windows and other OS's

[patrickhlauke]

now that #22500 is merged, i don't get the errors anymore...but intrigued still why it seemed to only happen on windows.

if the errors were just about spaces, i could have understood potential win/macOS/ubuntu differences. but as the linting errors were quite substantive (<label> without a for attribute etc), and clearly present in the markdown files, i think the issue may be more that the linter on macOS/ubuntu wasn't actually linting the right files/not all of them?

@patrickhlauke
This works better on OS X. Most recent branch version. The default *.html is used for html-lint after cwd is set:

"docs-lint": "htmlhint --config docs/.htmlhintrc _gh_pages/ js/tests/visual/ && htmllint --rc docs/.htmllintrc --cwd _gh_pages/ && htmllint --rc docs/.htmllintrc --cwd js/tests/visual/",

npm run docs-lint
> bootstrap@4.0.0-alpha.6 docs-lint /Users/piotrblazejewicz/git/bootstrap
> htmlhint --config docs/.htmlhintrc _gh_pages/ js/tests/visual/ && htmllint --rc docs/.htmllintrc --cwd _gh_pages/ && htmllint --rc docs/.htmllintrc --cwd js/tests/visual/

I think the issue here is that the HTML linters glob (asterisk wildcards) support is poor and on bash-based systems, bash expands the globs correctly, but on Windows the linter itself expands the glob incorrectly.

[patrickhlauke]

but on Windows the linter itself expands the glob incorrectly.

however, note that the linter on windows DID find actual invalid HTML in the docs output. so i'd argue that the end result is more accurate on windows, so if it's somehow possible to change this part of the build script to behave like it does on windows even on a mac/linux machine, that'd be best (otherwise there'll always be the problem of further errors in the docs output that go undiscovered until somebody on windows runs the build script)

[XhmikosR]

This doesn't happen for me.

Can we close it @patrickhlauke @bardiharborow ?

[patrickhlauke]

with all the very latest npm stuff, i get a clean [htmllint] found 0 errors out of 109 files ... assuming on macOS the situation is similar (and that it's indeed checking all the files, not just 21 files as in #22535 (comment)) then yes, closing this issue as resolved now.

[XhmikosR]

@patrickhlauke: the latter I fixed it a couple of days ago, see #24241. Surprisingly on Windows it was fine that is why it took me some time to notice it.
