> Please review a patch to remove incidental indentation from traditional doc > comments. This adds a `stripIndent()` method to the `Tokens.Comment` > interface and a new `JavadocTokenizer.StrippedComment` nested class that > implements indentation stripping while maintaining a map of position offsets > to the original comment. > > While the patch changes `javadoc` output by removing leading whitespace, the > change is generally not visible in the browser except in `<pre>` elements, > which is the point of this enhancement. > > The change affects most tree positions in the AST checker tests in > javac/doctree, but mostly does not affect the structure of the parsed trees, > with the exception of `BreakIterator` tests in `FirstSentenceTest.java`. > > `BreakIterator` does not recognize `.\n` immediately followed by a lower case > letter as sentence break, while it recognizes the break if the letter is an > upper-case letter *or* if there is a space between the line break and the > letter. I find this rule a bit peculiar but AFAICT we can't influence the > behavior of `BreakIterator`, so I have added tests that cover both lower and > upper-case behavior. > > The source position lookup in the stripped comment is implemented by creating > a new `OffsetMap` that translates from the stripped to the original comment, > then using the original comment's `OffsetMap` to translate the position to > the source file. `OffsetMap` is relatively lightweight (usually 2 `int[]` > elements per comment paragraph), so the added overhead is not too bad. > > Inspired by [JDK-8305688](https://bugs.openjdk.org/browse/JDK-8305688) I did > various test builds with restricted jobs and memory settings, but didn't > notice any change in processing or memory overhead to API docs builds.
