2026-07-06blame: reserve mark column only if necessaryRené Scharfe1-5/+6
git blame prepends commit hashes of boundary commits with "^", ignored commits with "?" and unblamable commits with "*" and reserves one column for them by extending the hash abbreviation, to avoid showing ambiguous hashes. This reserved column wastes precious screen space, which can be especially irritating when using the option -b to blank out boundary commit hashes and not ignoring any commits. Reserve it only as needed, i.e. if any of those cases are actually shown.

2026-01-09doc: git-blame: convert to new doc formatMichael Lyons1-35/+37
- Use _<placeholder>_ instead of <placeholder> in the description - Use _underscores_ around math associated with <placeholders> - Use `backticks` for keywords and more complex option descriptions. The new rendering engine will apply synopsis rules to these spans.

2025-11-17blame: make diff algorithm configurableAntonin Delpeuch1-0/+2
The diff algorithm used in 'git-blame(1)' is set to 'myers', without the possibility to change it aside from the `--minimal` option. There has been long-standing interest in changing the default diff algorithm to "histogram", and Git 3.0 was floated as a possible occasion for taking some steps towards that: https://lore.kernel.org/git/xmqqed873vgn.fsf@gitster.g/ As a preparation for this move, it is worth making sure that the diff algorithm is configurable where useful. Make it configurable in the `git-blame(1)` command by introducing the `--diff-algorithm` option and make honor the `diff.algorithm` config variable. Keep Myers diff as the default.

2025-04-07blame: print unblamable and ignored commits in porcelain modeKarthik Nayak1-4/+5
The 'git-blame(1)' command allows users to ignore specific revisions via the '--ignore-rev <rev>' and '--ignore-revs-file <file>' flags. These flags are often combined with the 'blame.markIgnoredLines' and 'blame.markUnblamableLines' config options. These config options prefix ignored and unblamable lines with a '?' and '*', respectively. However, this option was never extended to the porcelain mode of 'git-blame(1)'. Since the documentation does not indicate this exclusion, it is a bug. Fix this by printing 'ignored' and 'unblamable' respectively for the options when using the porcelain modes.

2025-01-21doc: use .adoc extension for AsciiDoc filesbrian m. carlson1-0/+257
We presently use the ".txt" extension for our AsciiDoc files. While not wrong, most editors do not associate this extension with AsciiDoc, meaning that contributors don't get automatic editor functionality that could be useful, such as syntax highlighting and prose linting. It is much more common to use the ".adoc" extension for AsciiDoc files, since this helps editors automatically detect files and also allows various forges to provide rich (HTML-like) rendering. Let's do that here, renaming all of the files and updating the includes where relevant. Adjust the various build scripts and makefiles to use the new extension as well. Note that this should not result in any user-visible changes to the documentation. Signed-off-by: brian m. carlson <sandals@crustytoothpaste.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
