This switches to using the tracing crate instead of log. Tracing
provides a lot of nice features which we can take advantage of moving
forward.
This also adjusts the output fairly significantly. This includes:
- Switched the environment variable from RUST_LOG to MDBOOK_LOG.
- Dropped the timestamp. I experimented with various different time
displays, but ultimately decided to omit it for now. I don't think
I've ever found it to be useful, and it takes up a very significant
amount of space. It could potentially be useful for basic profiling,
but I think there are other, better mechanisms for that. We could
consider leveraging tracing itself for doing some basic profiling
(like using something like tracing-chrome).
- Dropped the target unless MDBOOK_LOG is set. The target tends to be
pretty noisy, and doesn't really convey much information unless you
are debugging or otherwise trying to adjust the log output.
- Added color.
- Slightly reworked the way the error cause trace is displayed.
- Slightly changed the way html5ever filtering is done, as well as add
handlebars to the list since they both are very noisy. You can
override this now by explicitly listing them as targets.
I still expect that mdbook will eventually change how it displays things
to the console, possibly switching away from tracing and printing things
itself. However, that is a larger project for the future.
This adds a test to ensure that the interface for preprocessors and
renderers does not change unexpectedly, particularly in a semver
compatible release.
Closes https://github.com/rust-lang/mdBook/issues/1574
This test is failing on CI. I don't know why, as I cannot reproduce
locally. Perhaps it is due to the update to browser-ui-test? Or perhaps
some events from the new nav bar are delaying something?
This adds dynamic navigation of headers of the current page in the
sidebar. This is intended to help the user see what is on the current
page, and to be able to more easily navigate it. The "current" header is
tracked based on the scrolling behavior of the user, and is marked with
a small circle. This includes automatic folding to help keep it from
being too unwieldy on a page with a lot of nested headers.
This includes the `output.html.sidebar-header-nav` option to disable it.
I'm sure there are tweaks, fixes, and improvements that can be made. I'd
like to get this out now, and iterate on it over time to make
improvements.
This adds the ability to pass options to browser-ui-test, which can help
with debugging or doing things like snapshot work. It's maybe not the
cleanest since it doesn't support space-separated args, but should be
good enough.
This enables the hash-files setting by default. We have been running it
for a while, and it seems most of the issues have been resolved. This
should help with more reliably loading content like the toc contents.
This is helpful for matching patterns within a larger file. The error
message isn't quite as good, since it doesn't explicitly say "pattern
not found", but I think you can figure it out from the context.
This sprinkles track_caller on some more test functions to give more
useful line numbers on errors when a test fails.
read_to_string was changed since it couldn't track caller on a closure.
This renames the "sections" list to "items". In practice, this list has
contained more than just "sections" since parts were added. Also, the
rest of the code consistently uses the term "items", since the values it
contains are called `BookItem`s. Finally, the naming has always been a
little confusing to me.
This is a very disruptive change, and I'm not doing it lightly. However,
since there are a number of other API changes going into 0.5, I think
now is an ok time to change this.
This enables the smart-punctuation setting by default. The long term
plan is to continue to enable more markdown extensions by default across
semver breaking releases.
This adds `MarkdownOptions` for creating the pulldown-cmark parser, and
`HtmlRenderOptions` for converting markdown to HTML. These types should
help make it easier to extend the rendering options while remaining
semver compatible. It should also help with just general ergonomics of
using these functions.
This changes all HTML IDs so that they have the `mdbook-` prefix. This
should help avoid ID conflicts between internal IDs and IDs from user
content such as section headers.
This is a relatively disruptive change and has a high risk of breaking
something. However, I think I have covered everything, and if anything
is missed, hopefully it will get detected.
I did not change class names since the chance of a collision is much
smaller than with IDs. However, that is something that could be
considered in the future.
Closes https://github.com/rust-lang/mdBook/issues/880
This changes the `--dest-dir` flag so that it is relative to the current
directory, not the book root. This has been a source of confusion for
several people.
Fixes https://github.com/rust-lang/mdBook/issues/698
These tests have been flaky, and in general it was probably unwise to
try to rely on an external site like this. I was unable to determine
exactly why the test is failing. The page loads, and then puppeteer
throws an error.
I don't know if it is really feasible to bring these back in some form.
It's probably more effort than it is worth.
Closes https://github.com/rust-lang/mdBook/issues/2765
This changes `with_renderer` and `with_preprocessor` to replace any
extensions of the same name instead of just appending to the list. This
is necessary for rust-lang's build process, because we replace the
preprocessors with local ones. Previously, mdbook would just print an
error, but continue working. With the change that preprocessors are no
longer optional by default, it is now required that we have a way to
replace the existing entries.
This changes the serialization so that `book.src` is not serialized if
it is the default. This removes the somewhat pointless `src = "src"`
which shows up in the default `mdbook init` output. Deserialization
should still default to `"src"`.
This adds the `optional` field to the preprocessor configuration to
mirror the same option for the `output` table. Missing preprocessors are
now an error unless the `optional` field is set. This should help with
inadvertently building a book when a missing preprocessor that you
expect to be installed.
This changes preprocessors so that:
- Relative paths in the `command` value are relative to the book root.
- The process current directory is the book root.
This makes it so that it isn't dependent on the directory where `mdbook`
is executed.
Fixes https://github.com/rust-lang/mdBook/issues/1424
This removes the deprecated support for renderer paths that are relative
to the destination. Relative renderer command paths now must always be
relative to the book root.
This removes the deprecated `output.html.copy-fonts` option. This was
deprecated in https://github.com/rust-lang/mdBook/pull/1987. The
behavior now is that the default fonts are copied over unless there is a
custom `theme/fonts/fonts.css` file.
This changes it so that it is an error if there is ever an unknown
configuration field. This is intended to help avoid things like typos,
or using an outdated version of mdbook. Although it is possible that new
fields could potentially safely be ignored, setting up a warning system
is a bit more of a hassle. I don't think mdbook needs to have the same
kind of multi-version support as something like cargo does. However, if
this ends up being too much of a pain point, we can try to add a warning
system instead.
There are a variety of changes here:
- The top-level config namespace is now closed so that it only accepts
the keys defined in `Config`.
- All config tables now reject unknown fields.
- Added `Config::outputs` and `Config::preprocessors` for convenience
to access the entire `output` and `preprocessor` tables.
- Moved the unit-tests that were setting environment variables to the
testsuite where it launches a process instead.
Closes https://github.com/rust-lang/mdBook/issues/1595
This fixes an issue where the `check` methods would inadvertently
rebuild the books if the `mdbook build` command is run. Normally this
isn't too much of an issue unless the `build` command is run with
options that affect the output.
This switches all public types to use non_exhaustive to make it easier
to make additions without a semver-breaking change.
Some of the ergonomics are hampered due to the lack of exhaustiveness
checking. Hopefully some day in the future,
non_exhaustive_omitted_patterns_lint or something like it will get
stabilized.
Closes https://github.com/rust-lang/mdBook/issues/1835
A recent nightly changed the format of the panic message. This updates
the test that was matching against this so it doesn't match the text
that has changed.
