cscope for golang

从 https://gist.github.com/bopjiang/11146574 下载， 做了修改。

cscope-go.sh

 #!/bin/bash

 # generate cscope index files in current directory

 # the generated cscope index files also include go standard packages

 if [ "$GOROOT" = "" ] ; then

 echo "GOROOT is not set"

 GOROOT=`go env |grep "GOROOT" |cut -d "=" -f2`

 GOROOT=${GOROOT#\"}

 GOROOT=${GOROOT%\"}

 fi

 echo $GOROOT

 go_pkg_src=$GOROOT/pkg

 find $go_pkg_src -name "*.go" -print > cscope.files

 find . -name "*.go" -print >> cscope.files

 if cscope -b -k; then

         echo "Done"

 else

         echo "Failed"

         exit

 fi

也可以使用starscope

$ sudo apt-get install ruby-dev
$ sudo gem install starscope therubyracer execjs

$ cd ~/my-project
$ starscope
```

Ask it things directly:
```
$ starscope -q calls,new # Lists all callers of new
```

Export it to various existing formats for automatic integration with your editor:
```
$ starscope -e ctags
$ starscope -e cscope
