Git:查找所有标签，可从提交中访问

Question

如何列出所有标签，可从给定提交访问？

对于所有分支机构，它是git branch --all --merged <commit> .对于最近的标签，它是git describe .

手册页 git-tag建议 git tag -l --contains <commit> * , 但此命令不显示任何我知道可以访问的标签。

Answer 1

使用这个脚本打印出给定分支中的所有标签

git log --decorate=full --simplify-by-decoration --pretty=oneline HEAD | \
sed -r -e 's#^[^\(]*\(([^\)]*)\).*$#\1#' \
-e 's#,#\n#g' | \
grep 'tag:' | \
sed -r -e 's#[[:space:]]*tag:[[:space:]]*##'

该脚本只是一个 1 长行，被分解以适合发布窗口。

解释:

git log 

// Print out the full ref name 
--decorate=full 

// Select all the commits that are referred by some branch or tag
// 
// Basically its the data you are looking for
//
--simplify-by-decoration

// print each commit as single line
--pretty=oneline

// start from the current commit
HEAD

// The rest of the script are unix command to print the results in a nice   
// way, extracting the tag from the output line generated by the 
// --decorate=full flag.
