Find files copied in Mercurial

I notice a mistake in file original.txt. How can I then find all files copy.txt that have ever been created via hg copy original.txt copy.txt?

I looked at Mercurial revset. The only time "copies" are mentioned there is:

"follow([file[, startrev]])" An alias for "::." (ancestors of the working directory's first parent). If file pattern is specified, the histories of files matching given pattern in the revision given by startrev are followed, including copies.

So apparently using something like hg log -r "follow('copy.txt')" I could find that it was copied from original.txt, but not the inverse (where original.txt was copied to).

How can I find the copied files?

Dirty way

(may give FP without corrections on mergesets when signal-string merged to new file)

If you have unique data (across all files in repo) in original.txt you can grep repo for this string like hg grep -ldq "ID"

More natural way

Because renaming file for changeset is "delete old file, add new", you can

  • use "removes(pattern)" predicate in revset in form removes(original.txt)

  • use special template -T"{file_copies}\n" for log

    hg log -r "removes(original.txt)" -T"{file_copies}\n" original.txt

revset can be reused as parametrized revsetalias (for any file), log with revset+template can be also converted to alias

Addition

For less-noise output for "just copy" changesets modified revset can be used (TBT!, I'm too lazy)

-r "! modifies(original.txt)"
