You probably can move this line up with the others too.
And since you have broken this function down so nicely, it made me see
that we could do
item->magic = magic instead of returning "magic" at the end, which is
assigned to item->magic anyway by the caller.

These zeros look so lonely. I know it would exceed 80 columns if we
put it on the previous line. But I think it's ok for occasional
exceptions. Or you could rename noglob_global to noglob.

Yeah, I wanted to avoid global variables when there is no very good
reason for them to avoid possible libification work later.
And I don't think passing one parameter around to many functions is a
big burden.
Thanks for your reviews,

OK mine is "exclude the given tag from local history".
BTW the clone's string could be rephrased better because we know
there's no local history to begin with, if we stick to any verbs that
involves deepening or shortening.

* [PATCH v8 02/19] ref-filter: include reference to 'used_atom' within 'atom_value'
From: Karthik Nayak @ 2016-12-07 15:36 UTC (permalink / raw)
To: git; +Cc: jacob.keller, gitster, jnareb, Karthik Nayak, Karthik Nayak
In-Reply-To: <20161207153627.1468-1-Karthik.188@gmail.com>
From: Karthik Nayak <karthik.188@gmail.com>
Ensure that each 'atom_value' has a reference to its corresponding
'used_atom'. This let's us use values within 'used_atom' in the
'handler' function.
Hence we can get the %(align) atom's parameters directly from the
'used_atom' therefore removing the necessity of passing %(align) atom's
parameters to 'atom_value'.
This also acts as a preparatory patch for the upcoming patch where we
introduce %(if:equals=) and %(if:notequals=).

* [PATCH v8 00/19] port branch.c to use ref-filter's printing options
From: Karthik Nayak @ 2016-12-07 15:36 UTC (permalink / raw)
To: git; +Cc: jacob.keller, gitster, jnareb, Karthik Nayak
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)
v5b can be found here: $(gmane/292467)
v6 can be found here: http://marc.info/?l=git&m=146330914118766&w=2
v7 can be found here: http://marc.info/?l=git&m=147863593317362&w=2
Changes in this version:
1. use an enum for holding the comparision type in
%(if:[equals/notequals=...]) options.
2. rename the 'strip' option to 'lstrip' and introduce an 'rstrip'
option. Also modify them to take negative values. This drops the
':dri' and ':base' options.
3. Drop unecessary code.
4. Cleanup code and fix spacing.
5. Add more comments wherever required.
6. Add quote_literal_for_format(const char *s) for safer string
insertions in branch.c:build_format().
Thanks to Jacob, Jackub, Junio and Matthieu for their inputs on the
previous version.

* [PATCH v8 15/19] ref-filter: add an 'rstrip=<N>' option to atoms which deal with refnames
From: Karthik Nayak @ 2016-12-07 15:36 UTC (permalink / raw)
To: git; +Cc: jacob.keller, gitster, jnareb, Karthik Nayak
In-Reply-To: <20161207153627.1468-1-Karthik.188@gmail.com>
Complimenting the existing 'lstrip=<N>' option, add an 'rstrip=<N>'
option which strips `<N>` slash-separated path components from the end
of the refname (e.g., `%(refname:rstrip=2)` turns `refs/tags/foo` into
`refs`).

* [PATCH v8 10/19] ref-filter: introduce refname_atom_parser_internal()
From: Karthik Nayak @ 2016-12-07 15:36 UTC (permalink / raw)
To: git; +Cc: jacob.keller, gitster, jnareb, Karthik Nayak, Karthik Nayak
In-Reply-To: <20161207153627.1468-1-Karthik.188@gmail.com>
From: Karthik Nayak <karthik.188@gmail.com>
Since there are multiple atoms which print refs ('%(refname)',
'%(symref)', '%(push)', '%(upstream)'), it makes sense to have a common
ground for parsing them. This would allow us to share implementations of
the atom modifiers between these atoms.
Introduce refname_atom_parser_internal() to act as a common parsing
function for ref printing atoms. This would eventually be used to
introduce refname_atom_parser() and symref_atom_parser() and also be
internally used in remote_ref_atom_parser().

* [PATCH v8 16/19] ref-filter: allow porcelain to translate messages in the output
From: Karthik Nayak @ 2016-12-07 15:36 UTC (permalink / raw)

In-Reply-To: <20161207153627.1468-1-Karthik.188@gmail.com>
From: Karthik Nayak <karthik.188@gmail.com>
Introduce setup_ref_filter_porcelain_msg() so that the messages used in
the atom %(upstream:track) can be translated if needed. By default, keep
the messages untranslated, which is the right behavior for plumbing
commands. This is needed as we port branch.c to use ref-filter's
printing API's.

* [PATCH v8 09/19] ref-filter: make "%(symref)" atom work with the ':short' modifier
From: Karthik Nayak @ 2016-12-07 15:36 UTC (permalink / raw)
To: git; +Cc: jacob.keller, gitster, jnareb, Karthik Nayak, Karthik Nayak
In-Reply-To: <20161207153627.1468-1-Karthik.188@gmail.com>
From: Karthik Nayak <karthik.188@gmail.com>
The "%(symref)" atom doesn't work when used with the ':short' modifier
because we strictly match only 'symref' for setting the 'need_symref'
indicator. Fix this by comparing with the valid_atom rather than the
used_atom.
Add tests for %(symref) and %(symref:short) while we're here.

* [PATCH v8 18/19] branch: use ref-filter printing APIs
From: Karthik Nayak @ 2016-12-07 15:36 UTC (permalink / raw)
To: git; +Cc: jacob.keller, gitster, jnareb, Karthik Nayak
In-Reply-To: <20161207153627.1468-1-Karthik.188@gmail.com>
From: Karthik Nayak <karthik.188@gmail.com>
Port branch.c to use ref-filter APIs for printing. This clears out
most of the code used in branch.c for printing and replaces them with
calls made to the ref-filter library.
Introduce build_format() which gets the format required for printing
of refs. Make amendments to print_ref_list() to reflect these changes.
The strings included in build_format() may not be safely quoted for
inclusion (i.e. it might contain '%' which needs to be escaped with an
additional '%'). Introduce quote_literal_for_format() as a helper
function which takes a string and returns a version of the string that
is safely quoted to be used in the for-each-ref format which is built
in build_format().
Change calc_maxwidth() to also account for the length of HEAD ref, by
calling ref-filter:get_head_discription().
Also change the test in t6040 to reflect the changes.
Before this patch, all cross-prefix symrefs weren't shortened. Since
we're using ref-filter APIs, we shorten all symrefs by default. We also
allow the user to change the format if needed with the introduction of
the '--format' option in the next patch.

* [PATCH v8 14/19] ref-filter: modify the 'lstrip=<N>' option to work with negative '<N>'
From: Karthik Nayak @ 2016-12-07 15:36 UTC (permalink / raw)
To: git; +Cc: jacob.keller, gitster, jnareb, Karthik Nayak
In-Reply-To: <20161207153627.1468-1-Karthik.188@gmail.com>
Currently the 'lstrip=<N>' option only takes a positive value '<N>'
and strips '<N>' slash-separated path components from the left. Modify
the 'lstrip' option to also take a negative number '<N>' which would
only _leave_ behind 'N' slash-separated path components from the left.
Add documentation and tests for the same.

* [PATCH v8 13/19] ref-filter: rename the 'strip' option to 'lstrip'
From: Karthik Nayak @ 2016-12-07 15:36 UTC (permalink / raw)
To: git; +Cc: jacob.keller, gitster, jnareb, Karthik Nayak
In-Reply-To: <20161207153627.1468-1-Karthik.188@gmail.com>
In preparation for the upcoming patch, where we introduce the 'rstrip'
option. Rename the 'strip' option to 'lstrip' to remove ambiguity.

* [PATCH v8 17/19] branch, tag: use porcelain output
From: Karthik Nayak @ 2016-12-07 15:36 UTC (permalink / raw)
To: git; +Cc: jacob.keller, gitster, jnareb, Karthik Nayak
In-Reply-To: <20161207153627.1468-1-Karthik.188@gmail.com>
From: Karthik Nayak <karthik.188@gmail.com>
Call ref-filter's setup_ref_filter_porcelain_msg() to enable
translated messages for the %(upstream:tack) atom. Although branch.c
doesn't currently use ref-filter's printing API's, this will ensure
that when it does in the future patches, we do not need to worry about
translation.

* [PATCH v8 11/19] ref-filter: introduce refname_atom_parser()
From: Karthik Nayak @ 2016-12-07 15:36 UTC (permalink / raw)
To: git; +Cc: jacob.keller, gitster, jnareb, Karthik Nayak, Karthik Nayak
In-Reply-To: <20161207153627.1468-1-Karthik.188@gmail.com>
From: Karthik Nayak <karthik.188@gmail.com>
Using refname_atom_parser_internal(), introduce refname_atom_parser()
which will parse the %(symref) and %(refname) atoms. Store the parsed
information into the 'used_atom' structure based on the modifiers used
along with the atoms.
Now the '%(symref)' atom supports the ':strip' atom modifier. Update the
Documentation and tests to reflect this.

* [PATCH v8 12/19] ref-filter: make remote_ref_atom_parser() use refname_atom_parser_internal()
From: Karthik Nayak @ 2016-12-07 15:36 UTC (permalink / raw)
To: git; +Cc: jacob.keller, gitster, jnareb, Karthik Nayak, Karthik Nayak
In-Reply-To: <20161207153627.1468-1-Karthik.188@gmail.com>
From: Karthik Nayak <karthik.188@gmail.com>
Use the recently introduced refname_atom_parser_internal() within
remote_ref_atom_parser(), this provides a common base for all the ref
printing atoms, allowing %(upstream) and %(push) to also use the
':strip' option.
The atoms '%(push)' and '%(upstream)' will retain the ':track' and
':trackshort' atom modifiers to themselves as they have no meaning in
context to the '%(refname)' and '%(symref)' atoms.
Update the documentation and tests to reflect the same.

* [PATCH v8 07/19] ref-filter: make %(upstream:track) prints "[gone]" for invalid upstreams
From: Karthik Nayak @ 2016-12-07 15:36 UTC (permalink / raw)
To: git; +Cc: jacob.keller, gitster, jnareb, Karthik Nayak
In-Reply-To: <20161207153627.1468-1-Karthik.188@gmail.com>
From: Karthik Nayak <karthik.188@gmail.com>
Borrowing from branch.c's implementation print "[gone]" whenever an
unknown upstream ref is encountered instead of just ignoring it.
This makes sure that when branch.c is ported over to using ref-filter
APIs for printing, this feature is not lost.
Make changes to t/t6300-for-each-ref.sh and
Documentation/git-for-each-ref.txt to reflect this change.

* [PATCH v8 04/19] ref-filter: modify "%(objectname:short)" to take length
From: Karthik Nayak @ 2016-12-07 15:36 UTC (permalink / raw)
To: git; +Cc: jacob.keller, gitster, jnareb, Karthik Nayak
In-Reply-To: <20161207153627.1468-1-Karthik.188@gmail.com>
From: Karthik Nayak <karthik.188@gmail.com>
Add support for %(objectname:short=<length>) which would print the
abbreviated unique objectname of given length. When no length is
specified, the length is 'DEFAULT_ABBREV'. The minimum length is
'MINIMUM_ABBREV'. The length may be exceeded to ensure that the
provided object name is unique.
Add tests and documentation for the same.

* [PATCH v8 05/19] ref-filter: move get_head_description() from branch.c

In-Reply-To: <20161207153627.1468-1-Karthik.188@gmail.com>
From: Karthik Nayak <karthik.188@gmail.com>
Move the implementation of get_head_description() from branch.c to
ref-filter. This gives a description of the HEAD ref if called. This
is used as the refname for the HEAD ref whenever the
FILTER_REFS_DETACHED_HEAD option is used. Make it public because we
need it to calculate the length of the HEAD refs description in
branch.c:calc_maxwidth() when we port branch.c to use ref-filter
APIs.

* [PATCH v8 06/19] ref-filter: introduce format_ref_array_item()
From: Karthik Nayak @ 2016-12-07 15:36 UTC (permalink / raw)
To: git; +Cc: jacob.keller, gitster, jnareb, Karthik Nayak
In-Reply-To: <20161207153627.1468-1-Karthik.188@gmail.com>
From: Karthik Nayak <karthik.188@gmail.com>
To allow column display, we will need to first render the output in a
string list to allow print_columns() to compute the proper size of
each column before starting the actual output. Introduce the function
format_ref_array_item() that does the formatting of a ref_array_item
to an strbuf.
show_ref_array_item() is kept as a convenience wrapper around it which
obtains the strbuf and prints it the standard output.
