2017-07-10Merge branch 'rs/pretty-add-again' into maintLibravatar Junio C Hamano1-32/+0
The pretty-format specifiers like '%h', '%t', etc. had an optimization that no longer works correctly. In preparation/hope of getting it correctly implemented, first discard the optimization that is broken. * rs/pretty-add-again: pretty: recalculate duplicate short hashes
2017-06-15pretty: recalculate duplicate short hashesLibravatar René Scharfe1-32/+0
b9c6232138 (--format=pretty: avoid calculating expensive expansions twice) optimized adding short hashes multiple times by using the fact that the output strbuf was only ever simply appended to and copying the added string from the previous run. That prerequisite is no longer given; we now have modfiers like %< and %+ that can cause the cache to lose track of the correct offsets. Remove it.

2016-12-11pretty: add %(trailers) format for displaying trailers of a commit messageLibravatar Jacob Keller1-0/+17
Recent patches have expanded on the trailers.c code and we have the builtin commant git-interpret-trailers which can be used to add or modify trailer lines. However, there is no easy way to simply display the trailers of a commit message. Add support for %(trailers) format modifier which will use the trailer_info_get() calls to read trailers in an identical way as git interpret-trailers does. Use a long format option instead of a short name so that future work can more easily unify ref-filter and pretty formats. Add documentation and tests for the same.

2016-10-12gpg-interface: use more status lettersLibravatar Michael J Gruber1-0/+4
According to gpg2's doc/DETAILS: For each signature only one of the codes GOODSIG, BADSIG, EXPSIG, EXPKEYSIG, REVKEYSIG or ERRSIG will be emitted. gpg1 ("classic") behaves the same (although doc/DETAILS differs). Currently, we parse gpg's status output for GOODSIG, BADSIG and trust information and translate that into status codes G, B, U, N for the %G? format specifier. git-verify-* returns success in the GOODSIG case only. This is somewhat in disagreement with gpg, which considers the first 5 of the 6 above as VALIDSIG, but we err on the very safe side. Introduce additional status codes E, X, Y, R for ERRSIG, EXPSIG, EXPKEYSIG, and REVKEYSIG so that a user of %G? gets more information about the absence of a 'G' on first glance.

2016-06-06pretty: support "mboxrd" output formatLibravatar Eric Wong1-8/+25
This output format prevents format-patch output from breaking readers if somebody copy+pasted an mbox into a commit message. Unlike the traditional "mboxo" format, "mboxrd" is designed to be fully-reversible. "mboxrd" also gracefully degrades to showing extra ">" in existing "mboxo" readers. This degradation is preferable to breaking message splitting completely, a problem I've seen in "mboxcl" due to having multiple, non-existent, or inaccurate Content-Length headers. "mboxcl2" is a non-starter since it's inherits the problems of "mboxcl" while being completely incompatible with existing tooling based around mailsplit. ref: http://homepage.ntlworld.com/jonathan.deboynepollard/FGA/mail-mbox-formats.html Signed-off-by: Eric Wong <e@80x24.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2016-05-27format_commit_message: honor `color=auto` for `%C(auto)`Libravatar Edward Thomson1-1/+1
git-log(1) documents that when specifying the `%C(auto)` format placeholder will "turn on auto coloring on the next %placeholders until the color is switched again." However, when `%C(auto)` is used, the present implementation will turn colors on unconditionally (even if the color configuration is turned off for the current context - for example, `--no-color` was specified or the color is `auto` and the output is not a tty). Update `format_commit_one` to examine the current context when a format string of `%C(auto)` is specified, which ensures that we will not unconditionally write colors. This brings that behavior in line with the behavior of `%C(auto,<colorname>)`, and allows the user the ability to specify that color should be displayed only when the output is a tty. Additionally, add a test for `%C(auto)` and update the existing tests for `%C(auto,...)` as they were misidentified as being applicable to `%C(auto)`. Tests from Jeff King.

2016-03-30pretty: allow tweaking tabwidth in --expand-tabsLibravatar Junio C Hamano1-7/+8
When the local convention of the project is to use tab width that is not 8, it may make sense to allow "git log --expand-tabs=<n>" to tweak the output to match it. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2016-03-30pretty: enable --expand-tabs by default for selected pretty formatsLibravatar Junio C Hamano1-7/+11
"git log --pretty={medium,full,fuller}" and "git log" by default prepend 4 spaces to the log message, so it makes sense to enable the new "expand-tabs" facility by default for these formats. Add --no-expand-tabs option to override the new default. The change alone breaks a test in t4201 that runs "git shortlog" on the output from "git log", and expects that the output from "git log" does not do such a tab expansion. Adjust the test to explicitly disable expand-tabs with --no-expand-tabs. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2016-03-30pretty: expand tabs in indented logs to make things line up properlyLibravatar Linus Torvalds1-2/+69
A commit log message sometimes tries to line things up using tabs, assuming fixed-width font with the standard 8-place tab settings. Viewing such a commit however does not work well in "git log", as we indent the lines by prefixing 4 spaces in front of them. This should all line up: Column 1 Column 2 -------- -------- A B ABCD EFGH SPACES Instead of Tabs Even with multi-byte UTF8 characters: Column 1 Column 2 -------- -------- Ä B åäö 100 A Møøse once bit my sister.. Tab-expand the lines in "git log --expand-tabs" output before prefixing 4 spaces.

2015-06-29convert "enum date_mode" into a structLibravatar Jeff King1-14/+15
In preparation for adding date modes that may carry extra information beyond the mode itself, this patch converts the date_mode enum into a struct. Most of the conversion is fairly straightforward; we pass the struct as a pointer and dereference the type field where necessary. Locations that declare a date_mode can use a "{}" constructor. However, the tricky case is where we use the enum labels as constants, like: show_date(t, tz, DATE_NORMAL); Ideally we could say: show_date(t, tz, &{ DATE_NORMAL }); but of course C does not allow that. Likewise, we cannot cast the constant to a struct, because we need to pass an actual address. Our options are basically: 1. Manually add a "struct date_mode d = { DATE_NORMAL }" definition to each caller, and pass "&d". This makes the callers uglier, because they sometimes do not even have their own scope (e.g., they are inside a switch statement). 2. Provide a pre-made global "date_normal" struct that can be passed by address. We'd also need "date_rfc2822", "date_iso8601", and so forth. But at least the ugliness is defined in one place. 3. Provide a wrapper that generates the correct struct on the fly. The big downside is that we end up pointing to a single global, which makes our wrapper non-reentrant. But show_date is already not reentrant, so it does not matter. This patch implements 3, along with a minor macro to keep the size of the callers sane.

2014-10-14color_parse: do not mention variable name in error messageLibravatar Jeff King1-3/+2
Originally the color-parsing function was used only for config variables. It made sense to pass the variable name so that the die() message could be something like: $ git -c color.branch.plain=bogus branch fatal: bad color value 'bogus' for variable 'color.branch.plain' These days we call it in other contexts, and the resulting error messages are a little confusing: $ git log --pretty='%C(bogus)' fatal: bad color value 'bogus' for variable '--pretty format' $ git config --get-color foo.bar bogus fatal: bad color value 'bogus' for variable 'command line' This patch teaches color_parse to complain only about the value, and then return an error code. Config callers can then propagate that up to the config parser, which mentions the variable name. Other callers can provide a custom message. After this patch these three cases now look like: $ git -c color.branch.plain=bogus branch error: invalid color value: bogus fatal: unable to parse 'color.branch.plain' from command-line config $ git log --pretty='%C(bogus)' error: invalid color value: bogus fatal: unable to parse --pretty format $ git config --get-color foo.bar bogus error: invalid color value: bogus fatal: unable to parse default color value Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
