(收集)emacs下使用etags

在emacs里可以用etags命令生成emacs专用的tags文件，有了此文件之后便可以使用一些emacs tags的命令，比如对于编辑C/C++程序的人员可以方便的定位一个函数的定义，或者

对函数名进行自动补齐：   

find -name "*.[ch]" -exec etags -a {} \;

#!/bin/sh

trap "rm -f /tmp/$$" 0 1 2 3 15

rm -f ./TAGS

find `pwd`/ -type f -name "*.[chyl]" -print | \
xargs etags --append -o TAGS

find . -type d -print | \
while read DIR; do
  [ "$DIR" != "." ] && ln -f -s `pwd`/TAGS $DIR
done


#!/usr/bin/env python

#使用方法 比如要生成一个TAGS文件包括当前目录下的include和src目录以及子目录下所有的.c .h文件

#命令行： python ezetags -d./include:./src -e.h,.c


import sys

from getopt import *
from popen2 import *
def usage():
        sys.stdout.write("usage: ezetags <-dpath2:path2...> <-e.ext1,.ext2....>\n")

def parse_opt():
        opts,args = getopt(sys.argv[1:], "hd:e:", ["help"])
        dlist = None
        elist = None
        for f,v in opts:
                if f in ("-h", "--help"):
                        usage()
                        sys.exit()
                if f=="-e":
                        elist = v.split(',')
                if f=="-d":
                        dlist = v.split(':')
        return dlist,elist

def visit(arg, dirname, names):
        for n in names:
                nm,e = path.splitext(n)
                if e in arg[1]:
                        p = path.join(dirname,n)
                        p+="\n"
                        arg[0].write(p)
                        sys.stdout.write(p)

def main():

        if dlist==None or elist==None:
                usage()
                sys.exit()
        sys.stdout.write("dlist="+str(dlist)+" elist="+str(elist)+"\n")
        fout,fin = popen2("etags -")

                path.walk(d, visit, (fin,elist))
        sys.stdout.write("Done.\n")
