Back To Etags
In my previous post I wrote about using exuberant-ctags for emacs and Objective-C. But for some reason exuberant-ctags failed to create tags for funcions in /usr/include/string.h on my Mac. So, I switched back to etags. Here the correspondent shell script for generating tags for system headers on Mac OS X: #!/bin/sh s="\t " S="[$s]*" w="_a-zA-Z0-9" CN="[A-Z][$w]*" NM="[$w][$w]*" ETAGS="/Applications/Emacs.app/Contents/MacOS/bin/etags" cat /dev/null > tmp.tags find /usr/include -name "*.h" -exec \ $ETAGS -a --declarations -o tmp.tags \ "{}" ";" mv tmp.tags include.tags cat /dev/null > tmp.tags find /System/Library/Frameworks -name "*.h" -exec \ $ETAGS -a --declarations -o tmp.tags \ -r "/$S[-+]$S(\($S$NM\)\{1,3\}$S\**$S)?$S\($NM\)$S[:;]/\2/" \ "{}" ";" sed "/^@class/d" tmp.tags > Frameworks.tags rm tmp.tags
