would it be possible to get a synchronous version of the wonderful tool?

Looking at the README for the underlying library html-validator, that mentions offline validation (called WHATWG?), but does this CLI support that?

I tried

$ html-validator --validator WHATWG --file path/to/x.html

but it doesn't like that:

Error: Invalid URI "WHATWG"

Hello,

First of all I'd like to say that this is a great tool! It just works.
However, it seems that this tool only evaluates 1 page at a time.
I was wondering if there are any plans to include a crawl option so it evaluates the entire site within the same domain? (i.e., give it the homepage, and it'll recurisvely crawl the links with relative hrefs or pages with the same domain)
There was a tool developed for this purpose on npm called w3c-validator-cli, but it's deprecated.

Hello,
I'd like to ask you to implement support for specifying input files by globs. That would allow us to run html-validator-cli from build (e.g. npm) scripts in a portable (cross-platform) way. There is actually a lot of linters that accept globs already. They use minimatch AFAIK. I mean some module based on it like globby, glob-all, globule or simple-glob.

if you run it with quiet mode you only get the error messages
perhaps it would make sense to still include the url in the returned json object?

Please don't forget to create and push git tags for each release.

There is no way to see the changes since there's no changelog and comparing the tags can help a lot.

Hi, there.

We've been using your html-validator module in BootstrapCDN. Now, we need to switch to html-validator-cli.

So, I'm wondering, is there any way to ignore specific errors like the html-validator module allows?

There is an error with this repository's Renovate configuration that needs to be fixed. As a precaution, Renovate will stop PRs until it is resolved.

Error type: Preset name not found within published preset config (monorepo:angularmaterial). Note: this is a nested preset so please contact the preset author if you are unable to fix it yourself.

Hello, I found that entering certain invalid urls will still pass as valid as shown below

However, running the following code

(async () => {
  const validator = require('html-validator')
  let data = await validator({url: 'http://asdf'})
  console.log(data)
})()

outputs

{"url":"http://asdf","messages":[{"type":"non-document-error","subType":"io","message":"asdf: No address associated with hostname"}]}

which means html-validator is functioning correctly.

I think there just needs to be a check that includes checking for non-document-error.
If needed, I can submit a PR, and link here.

I'm trying to incorporate this tool into a build process but when run through npm test it doesn't return an error status code (1) so npm test thinks everything is fine.

If possible it would be great to provide the correct exit code so the tool can fail builds.

Hello,
I'd like to ask you to implement (and document) support for specifying multiple input files (without a need to prefix every file name with a command line option). That would allow us to run html-validator-cli from build (e.g. npm) scripts. There is actually a lot of linters that accept multiple files already.

html-validator --quiet returns only errors

I am looking for a solution to validating files in my local development environment. When I point to a local dev url, I get the message

IO Error: local.dev: Name or service not known

Is there a way I could solve this problem using this tool?
