Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
revset: add diff(pattern) predicate for "grep --diff" I find this is useful in GUI log viewer since the tool only needs to support "log -rREV" command. This is basic implementation. Windowed search is not implemented since it wouldn't work pretty well with the smartset API. And filename matcher is not supported because the syntax isn't determined. My idea is to add handling of diff(pattern, file(..)) and diff(pattern, follow(..)), which will then be evolved to a full revset+matcher combinator support: x & diff(pattern, y & z) ===== y & z builds (revs(y) & revs(z), matcher(y) & matcher(z)) pair, and narrows the search space of diff() ==================== diff() returns matched (revs, matcher) pair ======================== revs and matcher will be combined respectively by &-operator, and the matcher will optionally be used to filter "hg log -p" output The predicate name "diff()" wouldn't be great, but grep() is already used. Another options I can think of are "grepdiff()" and "containsdiff()". Naming suggestions are welcome.
