`git reflog`默認輸出的格式字符串是什麼？

Question

我想調整git reflog的默認輸出，但我首先需要格式字符串來重現默認輸出。具體地講，我無法用不同refnames的着色：

有人更見地使用Git能幫助我嗎？

每the git reflog documentation：

git reflog show是git log -g --abbrev-commit --pretty=oneline

一個別名，然後應該送你到the git log documentation，它說一點關於--pretty=oneline，卻隱藏着下-g又名--walk-reflogs說明一個重要的位：

With --pretty格式不是oneline（出於顯而易見的原因），這會導致輸出從reflog中獲取兩行額外的信息。在輸出中的引用日誌指示符可被示爲ref@{Nth}（其中Nth是在引用日誌的逆時間指數）或作爲ref@{timestamp}（與時間戳該條目），這取決於幾個規則：

1. 如果起始點指定爲ref@{Nth}，顯示索引格式。

2. 如果起始點被指定爲ref@{now}，請顯示時間戳格式。

3. 如果兩者均未使用，但在命令行中給出​​，請以​​所請求的格式顯示時間戳。

4. 否則，顯示索引格式。

在--pretty=oneline之下，提交消息在同一行上以該信息爲前綴。該選項不能與--reverse結合使用。另請參閱git-reflog(1)。

的「起點」這一暗示是你與你的git log -g命令鳴哨引用日誌條目。如果你沒有給一個，git log默認爲HEAD，不具有任何格式，所以這屬於規則3或4：

git log --pretty=oneline -g HEAD@{now} 

明確使用規則2，但：

git log --pretty=oneline -g HEAD@{0} 

例如明確使用規則1。

小，它說，或者不說，大約--pretty=oneline是，它是大致相當於這取決於您是否使用--abbrev-commit%H %gd %s或%h %gd %s。但是如果你在配置文件中設置了log.decorate=auto和標準輸出將進入一個交互設備，那麼你也可以從%d中插入。

的默認格式字符串reflog是這樣的：

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

顏色可以與%C進行修改。例如，爲了最初的黃色變爲品紅色：

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

注意%C(reset)是絕對必要的，因爲着色是使用ANSI escape sequences和它們必須被正確端接實現。如果您是古怪的，請查看color.h的git代碼，查看這些序列的外觀。

對於所有可能的格式字符串看到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)
