git - `git reflog` 默认输出的格式字符串是什么？

Question

我想调整 git reflog 的默认输出，但我首先需要格式字符串来重现默认输出。具体来说，我在为不同的 refnames 着色时遇到了问题:

有更了解 Git 的人可以帮助我吗？

Answer 1

reflog 的默认格式字符串是这样的:

git reflog --format='%C(auto)%h %gd: %gs (%s)'

可以使用 %C 修改颜色.例如，要将初始黄色更改为洋红色:

git reflog --format='%C(magenta)%h%C(reset) %gd: %gs (%s)'

请注意 %C(reset)是绝对必要的，因为着色是使用 ANSI escape sequences 实现的并且它们必须正确终止。如果您有好奇心，请查看 color.h在git代码以查看这些序列的外观。

对于所有可能的格式字符串，请参阅 format:<string>在man git-log :

   ·   format:<string>

       The format:<string> format allows you to specify which information you want to show. It works a little
       bit like printf format, with the notable exception that you get a newline with %n instead of \n.

       E.g, format:"The author of %h was %an, %ar%nThe title was >>%s<<%n" would show something like this:

           The author of fe6e0ee was Junio C Hamano, 23 hours ago
           The title was >>t4119: test autocomputing -p<n> for traditional diff input.<<

       The placeholders are:

       ·   %H: commit hash

       ·   %h: abbreviated commit hash

       ·   %T: tree hash

       ·   %t: abbreviated tree hash

       ·   %P: parent hashes

       ·   %p: abbreviated parent hashes

       ·   %an: author name

       ·   %aN: author name (respecting .mailmap, see git-shortlog(1) or git-blame(1))

       ·   %ae: author email

       ·   %aE: author email (respecting .mailmap, see git-shortlog(1) or git-blame(1))

       ·   %ad: author date (format respects --date= option)

       ·   %aD: author date, RFC2822 style

       ·   %ar: author date, relative

       ·   %at: author date, UNIX timestamp

       ·   %ai: author date, ISO 8601-like format

       ·   %aI: author date, strict ISO 8601 format

       ·   %cn: committer name

       ·   %cN: committer name (respecting .mailmap, see git-shortlog(1) or git-blame(1))

       ·   %ce: committer email

       ·   %cE: committer email (respecting .mailmap, see git-shortlog(1) or git-blame(1))

       ·   %cd: committer date (format respects --date= option)

       ·   %cD: committer date, RFC2822 style

       ·   %cr: committer date, relative

       ·   %ct: committer date, UNIX timestamp

       ·   %ci: committer date, ISO 8601-like format

       ·   %cI: committer date, strict ISO 8601 format

       ·   %d: ref names, like the --decorate option of git-log(1)

       ·   %D: ref names without the " (", ")" wrapping.

       ·   %e: encoding

       ·   %s: subject

       ·   %f: sanitized subject line, suitable for a filename

       ·   %b: body

       ·   %B: raw body (unwrapped subject and body)

       ·   %N: commit notes

       ·   %GG: raw verification message from GPG for a signed commit

       ·   %G?: show "G" for a good (valid) signature, "B" for a bad signature, "U" for a good signature with
           unknown validity and "N" for no signature

       ·   %GS: show the name of the signer for a signed commit

       ·   %GK: show the key used to sign a signed commit

       ·   %gD: reflog selector, e.g., refs/stash@{1}

       ·   %gd: shortened reflog selector, e.g., stash@{1}

       ·   %gn: reflog identity name

       ·   %gN: reflog identity name (respecting .mailmap, see git-shortlog(1) or git-blame(1))

       ·   %ge: reflog identity email

       ·   %gE: reflog identity email (respecting .mailmap, see git-shortlog(1) or git-blame(1))

       ·   %gs: reflog subject

       ·   %Cred: switch color to red

       ·   %Cgreen: switch color to green

       ·   %Cblue: switch color to blue

       ·   %Creset: reset color

       ·   %C(...): color specification, as described in color.branch.* config option; adding auto, at the
           beginning will emit color only when colors are enabled for log output (by color.diff, color.ui, or
           --color, and respecting the auto settings of the former if we are going to a terminal).  auto
           alone (i.e.  %C(auto)) will turn on auto coloring on the next placeholders until the color is
           switched again.

       ·   %m: left, right or boundary mark

       ·   %n: newline

       ·   %%: a raw %

       ·   %x00: print a byte from a hex code

       ·   %w([<w>[,<i1>[,<i2>]]]): switch line wrapping, like the -w option of git-shortlog(1).

       ·   %<(<N>[,trunc|ltrunc|mtrunc]): make the next placeholder take at least N columns, padding spaces
           on the right if necessary. Optionally truncate at the beginning (ltrunc), the middle (mtrunc) or
           the end (trunc) if the output is longer than N columns. Note that truncating only works correctly
           with N >= 2.

       ·   %<|(<N>): make the next placeholder take at least until Nth columns, padding spaces on the right
           if necessary

       ·   %>(<N>), %>|(<N>): similar to %<(<N>), %<|(<N>) respectively, but padding spaces on the left

       ·   %>>(<N>), %>>|(<N>): similar to %>(<N>), %>|(<N>) respectively, except that if the next
           placeholder takes more spaces than given and there are spaces on its left, use those spaces

       ·   %><(<N>), %><|(<N>): similar to % <(<N>), %<|(<N>) respectively, but padding both sides (i.e. the
           text is centered)
