This code is not directly related to the template parser, so it
can safely live in its own file.
The only significant change to the code is to the signature of
`html_branches` so that it can be called without requiring a file.
Since it's only used in html_grep, that has been updated to reflect
this change.
Fixes: #1774.
Fixed IndexError when there is only zero or more whitespace characters
between < and >. (str.split() will return an empty list in this case, which
means there is no index 0.)
* Replace generic Exception with TemplateParserException.
* Add tests to cover many of the uncovered lines in
tools/lib/template_parser.py.
* Add an exclusion line to the naïve pattern for checking for missing
tuples in format strings, to keep the linter happy.
This starts to address 1533. I still think the </p> tags
should be on their own line lined up with the start tag,
so the linter won't let through the specific example
shown in the ticket.
We were ignoring singleton tags like "input" tags in
html-grep. This was an artifact of our tokenizer originally
being built to check indentation of templates, for which
singleton tags had been a distraction. This fix actually cleans up
the template checking logic as well, since it can now rely
on the tokenizer to classify special tags and singleton tags.
The tokenizer is more complete and more specific.
