This changes the internal error message to a warning to let the user
know that the HTML tags are unbalanced. In the future this will be a
denyable lint.
This is a very primitive approach of just ignoring the end tag. Ideally
it should recover using the standard HTML parsing algorithm, since there
is a chance that there will be a cascade of errors under certain
unbalanced situations.
This checks for any unclosed elements when processing is finished. This
is intended to detect invalid HTML in the source, or bugs in the tree
builder. Raw HTML elements generate a warning (which in the future will
be a configurable lint). All other sync errors are internal errors as
they are not expected, and it would be helpful to know if they ever
happen.
This switches from ASCII lowercase to Unicode lowercase when generating
heading IDs. This brings mdbook more in line with other tools and sites
when they generate heading IDs. The generation still isn't 100% the same
as other tools and sites, but it is usually the same in most cases.
Closes https://github.com/rust-lang/mdBook/issues/1059
With the migration to Font Awesome 6, I'm running into books where the
icon names are missing or have changed. This adds a warning to help
identify those situations.
This fixes links on the print page that go to an internal destination
that is not a chapter. The path would have the wrong relative
destination, and would be broken. The logic for detecting this was
incorrectly only checking if a link went outside the book, or didn't
have an html extension. This doesn't work for links to HTML files that
are inside the book, but not one of the chapters.
This changes it so that header and `<dt>` tags manually written as HTML
are not modified (no anchor, no id, etc.). This is to avoid mangling any
HTML that the user explicitly crafted.
I'm not sure what the fallout from the headers might be, since I'm not
100% sure there aren't uses where the user wanted mdbook to modify
manual HTML. However, I don't see any in rust-lang's use.
This adds the method `contains_key` to assist with detecting if a key is
set in the config. There have been a few scenarios where I have needed
this when upgrading to 0.5. For now this only supports the `output` and
`preprocessor`. Checking the presence in the other tables isn't easy,
but could potentially be added if needed.
