Ignore specific files

Hi, nowhere in the doc I can find how to ignore a specific file:

I get many errors with my Google validation file:

googlebdb6f8bf41a883bb.html":1.1-1.52: error: Element "head" is missing a required instance of child element "title". googlebdb6f8bf41a883bb.html":1.1-1.52: error: Non-space characters found without seeing a doctype first. Expected "<!DOCTYPE html>". googlebdb6f8bf41a883bb.html":1.1-1.52: info warning: Consider adding a "lang" attribute to the "html" start tag to declare the language of this document.

Is it a new feature or not specified in doc ? Thanks a lot

Problem verifying download

I downloaded the release and associated signatures and checksums from the github repository ( However I have two problems verifying the download:

  1. There is a gpg signature, but I can't find where the public key is, therefore I can't check it;

  2. The md5 and sha1 checksums are malformed according to the command output, e.g.

md5sum -c
md5sum: no properly formatted MD5 checksum lines
sha1sum -c
sha1sum: no properly formatted SHA1 checksum
lines found

Can you advise on where to obtain the GPG key, and if the above checksum behavior is normal, or am I making a mistake.

Unable to show outline

¿La página web que estaba validando es pública? Si es así, publicar la URL aquí sería de gran ayuda.

Unable to show outline

I validated a web with All are ok, but i received a warning message, said that:

Unable to show outline. (Most likely due to a malformed HTTP response from the server hosting the document that was checked.)

By this way, I can't watch the Heading-level outline - that is necessary for me. Where can i looking for solved it?

Enable filtering also on the file path prefix

Note that usually you get multiple error messages caused by a single error, e.g.:

"file:/home/test/invalid.html":230.42-230.50: error: Element “invalid” not allowed as child of element “p” in this context. (Suppressing further errors from this subtree.)
"file:/home/test/invalid.html":230.82-230.85: error: End tag “p” seen, but there were open elements.
"file:/home/test/invalid.html":230.42-230.50: error: Unclosed element “invalid”

And it's not much comfortable to filter out each single message.

Enable filtering also on the file path prefix

Currently the filter pattern matches only the error message. It would be handy to match also in the path part to enable filtering based on the filename or even the specific line number.

/home/test/somepath/SomeFile.html:230.42-230.50: error: Element “invalid” not allowed as child of element “p” in this context. (Suppressing further errors from this subtree.)

It would nice to be allowed to use filter patterns like: .*SomeFile.html.* or even .*SomeFile.html:230.*.

Missing </html> doesn't throw an error

When doing an upload/direct input no error is thrown if the </html> tag is missing. Example:


As most HTML is forgiving, this of course works. But best practice is to close all tags that are opened. This should throw an error/warning.
