This fixes an issue where the sidebar was scrolling incorrectly when
clicking on chapters when a heading nav is currently in view. The
problem was that it was storing the scrollTop of the sidebar, but it was
not considering that when navigating to another chapter that the heading
nav of the previous chapter would disappear.
The solution is to keep of an offset instead so that it can make sure
that the vertical position of the clicked chapter stays in the same
relative position when the new page loads.

This fixes a problem where custom preprocessors were not being
registered when running tests. This was caused by the test function
rebuilding the preprocessor map.
This removes the code that was rebuilding the preprocessors and removing
the IndexPreprocessor when running tests. Skipping IndexPreprocessor was
added back in https://github.com/rust-lang/mdBook/pull/741 to fix
https://github.com/rust-lang/mdBook/issues/724 which was caused by
https://github.com/rust-lang/mdBook/pull/685 which added the
IndexPreprocessor.
Additionally, https://github.com/rust-lang/mdBook/pull/1986 added
running *all* preprocessors.
The IndexPreprocessor was removed because in the past the code was
testing against the source directly, and the path from `chapter.path` is
the converted `index.md` file, and that filename does not exist in the
source. This isn't a problem anymore because due to
https://github.com/rust-lang/mdBook/pull/891 it is not reading from the
`src` directory.
Note that this results in a minor change where the chapter path changes
from `README.md` to `index.md` in the output and the `--chapter` option.
I think I'm ok with that change, though it would be easy to switch it
back if that's an issue.
This fixes an issue where when a heading goes from a larger to a smaller
level, it was going back too far so that subsequent headings would be at
a lower level than they should have been.

This checks the entire structure of the heading nav for this test. It
currently is not handling nesting properly.
Having a large inline string like this may not be the easiest to
maintain or be able to see the structure. I don't see a way to format it
in goml.
This changes it so that top-level environment variable config keys like
`MDBOOK_FOO` are ignored instead of generating an error. It's just too
inconvenient since it is common for users to set environment variables
like `MDBOOK_VERSION` or whatever for their own scripts.
In version 6, Font Awesome changed so that the class names look like
`fa-solid fa-cat` instead of `fas fa-cat`. This updates so that it
handles this new style.
This adds several changes to how environment variables are handled to
more closely align with how configs are handled, and to fix an issue
with replacing entire tables. The changes are:
- Top-level tables like `MDBOOK_BOOK` now *replace* the contents of the
`book` table instead of merging it. This adds consistency with how all
the other environment objects work.
- Fixed allowing top-level replacement of `MDBOOK_BOOK` and
`MDBOOK_OUTPUT`. This was inadvertently recently broken.
- Added ability to replace top-level `MDBOOK_RUST`. I don't recall why
that wasn't included.
- Reject invalid keys like `MDBOOK_FOO`.
- Reject unknown keys, like `MDBOOK_BOOK='{"xyz": 123}'`
- Reject invalid types, like `MDBOOK_BOOK='{"title": 123}'`
This fixes an issue where it was panicking due to an unbalanced HTML tag
when exiting a markdown element. The problem was that the tag stack was
left non-empty when processing was finished due to `end_tag` being out
of sync with the pulldown-cmark event tags.
There really should be better validation that the stack is in sync and
balanced, but this should address the main culprit of the interplay of
raw HTML tags and pulldown-cmark events.
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.
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 makes sure that the sidebar headings don't have the `<mark>` tag.
When these are created, the Marker is unable to remove them from the
sidebar (and we don't want them there in the first place).
I suspect we'll want more filtering in the future, but I'm not sure
exactly what to filter. Alternatively, it could have an allow list of
tags, and filter all others out.
This updates the header navigation so that:
- Added a colored bar to break it apart from the chapter navigation.
- Removed the colored circle and just use link color to make it
look cleaner.
This fixes an issue when folding is enabled. The folding was not
properly hiding the sub-chapters because it was assuming it could hide
the next list element. However, the heading nav was the next list
element, so the remaining chapters remained visible.
The solution required some deeper changes to how the chapters were
organized in the sidebar. Instead of nested chapters being a list
element *sibling*, the nested chapter's `ol` is now a *child* of its
parent chapter. This makes it much easier to just hide everything
without regard of the exact sibling order.
This required wrapping the chapter title and the toggle chevron inside a
span so that the flex layout could be localized to just those elements,
and allow the following `ol` elements to lay out regularly.

This is no longer used, as individual books have been added to support
different GUI tests. If there is anything here that we later decide we
need to keep for whatever reason, the needed content can be brought back
as new GUI test books. Otherwise, the guide and other books should cover
most things here.
This adds the all-summary GUI test book which can be used for general
purpose tests that need a few pages to exercise all the different kinds
of items.
This adds the ability to use multiple books for the GUI tests. This is
helpful since some tests need special configuration, and sharing the
same book can make it difficult or impossible to test different
configurations. It also makes it difficult to make changes to the
test_book since it can affect other tests.
This works by placing the books in the tests/gui/books directory. The
test runner will automatically build all the books. The gui tests can
then just access the DOC_PATH with the name of the book.
Books are now saved in a temp directory to make it easier to use the
DOC_PATH variable, instead of being tests/gui/books/book_name/book which
is a little awkward.
Following commits will restructure the existing book. This is just a
mechanical move.
This does a little cleanup around the usage of filesystem functions:
- Add `mdbook_core::utils::fs::read_to_string` as a wrapper around
`std::fs::read_to_string` to provide better error messages. Use
this wherever a file is read.
- Add `mdbook_core::utils::fs::create_dir_all` as a wrapper around
`std::fs::create_dir_all` to provide better error messages. Use
this wherever a file is read.
- Replace `mdbook_core::utils::fs::write_file` with `write` to mirror
the `std::fs::write` API.
- Remove `mdbook_core::utils::fs::create_file`. It was generally not
used anymore.
- Scrub the usage of `std::fs` to use the new wrappers. This doesn't
remove it 100%, but it is now significantly reduced.
This enables the admonitions support from pulldown-cmark. This includes
a config option in case it causes problems with existing books.
I would like to make this extensible in the future, though I'm not sure
what that would look like. There's also some concerns with how this will
affect translations like mdbook-i18n-helpers, which we may need to work
out in a different way.

This fixes a collision with the ID generation where it a previous entry
could generate a unique ID like "foo-1", but then a header with the text
"Foo 1" would collide with it. This fixes it so that when generating the
ID for "Foo 1", it will loop unit it finds an ID that doesn't collide
(in this case, `foo-1-1`).
This fixes a small mistake where the "raw" status wasn't being reset
once exiting the script or style tags. That means any text nodes that
followed would be misinterpreted as being raw.
