Eric Huss	723d9df6c7	serve: Fix repeated error message when HTML config is invalid This fixes an issue where `mdbook serve` would repeatedly show an error message every second if the `output.html` config had a problem. The issue is that `set_roots` was doing more work than I realized. It is not necessary to call it every time in the main polling loop, since the roots only change when the book configuration changes. The solution is to just reset the roots whenever the book config changes. Fixes https://github.com/rust-lang/mdBook/issues/2946	2025-12-11 11:22:16 -08:00

Eric Huss	59017ea918	Fix sidebar scroll position when heading nav is involved 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. Fixes https://github.com/rust-lang/mdBook/issues/2967	2025-12-11 11:13:47 -08:00

Eric Huss	23724b0a6b	Fix color for rustdoc error messages Due to a change in tracing-subscriber where it escapes ANSI codes, the output from rustdoc was changed to be escaped instead of colored. This fixes the issue by just printing to the console directly. This does not have a test because it is difficult to emulate a terminal in the testsuite, and I don't feel like adding color overrides at the moment. Ref: - https://github.com/rust-lang/mdBook/pull/2829 -- Switched to tracing - https://github.com/advisories/GHSA-xwfj-jgwm-7wp5 -- CVE-2025-58160 - https://github.com/tokio-rs/tracing/issues/3378 -- Discussion of supporting color codes. Eventually mdbook's primary output should migrate away from using log messages, and instead use a structured console system. However, that's a ways off.	2025-12-10 14:01:50 -08:00
Eric Huss	7bdea7c085	Don't rebuild preprocessor map during test 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.	2025-12-10 13:42:15 -08:00
