To describe the bug this fix is addressing, one can do
``$ hg status -T "{label('red', path)}\n" --color=debug``
and observe that the label is not applied before my fix and applied with it.
The home of 'Abort' is 'error' not 'util' however, a lot of code seems to be
confused about that and gives all the credit to 'util' instead of the
hardworking 'error'. In a spirit of equity, we break the cycle of injustice and
give back to 'error' the respect it deserves. And screw that 'util' poser.
For great justice.
This lets all the non-log commands that use the formatter use
templates. There are still some things that don't work, for instance:
- color (needs "repo" in map)
- shortest (needs "ctx" in map)
We want to share this function between formatter and cmdutils. It
doesn't belong in templater because it imports knowledge of ui layers
that shouldn't be there. We'd prefer cmdutil to layer on the formatter
rather than vice-versa. Since the formatter is the handler for -T
options for all non-log commands, let's move the helper there. We
leave the bits specific to the old --style option behind.
This seems a bit awkward, but it can avoid duplicates in annotate, tags,
branches and bookmarks.
I guess fm.hexfunc can eventually be removed (or redesigned) when it gets
template backend.
This is necessary for "annotate" to encode ctx.date() in the same manner
as jsonchangeset printer.
It doesn't support list object because keeping mutable object in _item could
be a source of hidden bugs. Also, I can't think of the use case.
This alternate syntax was proposed by Bryan O'Sullivan in a review of
441ebe37ceb5. I haven't been able to measure any particular performance
difference, but the new syntax is more concise and easier to read.
