A rule to match 20 characters or more of non-whitespace in code tags?

[adamwolf]

Hi folks!

I work on a site sometimes where we have to be careful about long words in code tags. They don't wrap unless we insert tags. I'd love to make a rule that looks for the long words and warns me, but I can't quite figure it out.

I had something like this:

# I sometimes get wrapping issues when I have long sequences without whitespace in <code> or <pre>.

extends: existence
message: "Avoid using long sequences without whitespace inside code blocks: '%s'"
level: warning
scope: ...?
# Regex to match non-whitespace sequences (e.g., sequences longer than X characters)
raw:
  - '\S{20,}'

but, of course, it isn't really right.

Is there a way to search over (and limit to?) the things inside backticks in Markdown or <code> or <pre> tags in html?
