This is part of unification of the commands 'git tag -l, git branch -l
and git for-each-ref'. This ports over branch.c to use ref-filter's
printing options.
Initially posted here: $(gmane/279226). It was decided that this series
would follow up after refactoring ref-filter parsing mechanism, which
is now merged into master (9606218b32344c5c756f7c29349d3845ef60b80c).
v1 can be found here: $(gmane/288342)
v2 can be found here: $(gmane/288863)
v3 can be found here: $(gmane/290299)
v4 can be found here: $(gmane/291106)
Changes in this version:
1. Rebased on top of jk/branch-shortening-funny-symrefs ($gmane/291295).
2. Introduced refname_atom_parser_internal() to act as a common ground
for ref-printing atoms. Written by Jeff ($gmane/291497).
3. Ensure that ':dir', 'base', 'strip' is available to all ref-printing
atoms. Written by Jeff.
4. Fix a memory leak which was reported by Stefan ($gmane/291703).
Thanks to Junio, Jeff and Stefan for suggestions on the previous version.
Karthik Nayak (16):
ref-filter: include reference to 'used_atom' within 'atom_value'
ref-filter: implement %(if:equals=<string>) and
%(if:notequals=<string>)
ref-filter: modify "%(objectname:short)" to take length
ref-filter: move get_head_description() from branch.c
ref-filter: introduce format_ref_array_item()
ref-filter: make %(upstream:track) prints "[gone]" for invalid
upstreams
ref-filter: add support for %(upstream:track,nobracket)
ref-filter: make "%(symref)" atom work with the ':short' modifier
ref-filter: introduce refname_atom_parser_internal()
ref-filter: introduce symref_atom_parser() and refname_atom_parser()
ref-filter: make remote_ref_atom_parser() use
refname_atom_parser_internal()
ref-filter: add `:dir` and `:base` options for ref printing atoms
ref-filter: allow porcelain to translate messages in the output
branch, tag: use porcelain output
branch: use ref-filter printing APIs
branch: implement '--format' option
