寫 code 當總統(握拳)

為 Git 管理下的檔案，自動加上 Revision 或 Id 資訊

這個功能在 cvs 及 svn 上已經很久了，沒有道理 git 沒有 -- timchen119 如是說。 於是在 timchen119 『使徒提姆』 的幫助下，我找到了 git 的作法。

ident $Id$

$ echo '*.txt ident' >> .gitattributes
$ echo '$Id$' > test.txt
$ rm text.txt
$ git checkout -- text.txt
$ cat test.txt 
$Id: 42812b7653c7b88933f8a9d6cad0ca16714b9bb3 $

export-subst $Format:$

$ echo 'Last commit date: $Format:%cd$' > LAST_COMMIT
$ echo "LAST_COMMIT export-subst" >> .gitattributes
$ git add LAST_COMMIT .gitattributes
$ git commit -am 'adding LAST_COMMIT file for archives'
$ git archive HEAD | tar x LAST_COMMIT -O
Last commit date: $Format:Tue Apr 21 08:38:48 2009 -0700$

make export-subst like SVN $ID$ format

110碼:AAA2369 $> echo '*.txt export-subst' >> .gitattributes
110碼:AAA2369 $> echo 'Id: $Format:%t %ai %an$' > format.txt
110碼:AAA2369 $> git commit -am 'adding format.txt file for archives'
110碼:AAA2369 $> git archive HEAD | tar x format.txt -O

more $Format:PLACEHOLDERS$

$ man git-log
search "placeholders" <-- this keyword 

• %H: commit hash
• %h: abbreviated commit hash
• %T: tree hash
• %t: abbreviated tree hash
• %P: parent hashes
