Add the following to your ~/.bash_completion
file (create it if it does not exist):
_vim_ctags() { local cur prev COMPREPLY=() cur="${COMP_WORDS[COMP_CWORD]}" prev="${COMP_WORDS[COMP_CWORD-1]}" case "${prev}" in -t) # Avoid the complaint message when no tags file exists if [ ! -r ./tags ] then return fi # Escape slashes to avoid confusing awk cur=${cur////\\/} COMPREPLY=( $(compgen -W "`awk -v ORS=" " "/^${cur}/ { print \\$1 }" tags`" ) ) ;; *) # Perform usual completion mode ;; esac } # Files matching this pattern are excluded excludelist='*.@(o|O|so|SO|so.!(conf)|SO.!(CONF)|a|A|rpm|RPM|deb|DEB|gif|GIF|jp?(e)g|JP?(E)G|mp3|MP3|mp?(e)g|MP?(E)G|avi|AVI|asf|ASF|ogg|OGG|class|CLASS)' complete -F _vim_ctags -f -X "${excludelist}" vi vim gvim rvim view rview rgvim rgview gview
Once you restart your bash session (or create a new one) you can type:
~$ vim -t MyC<tab key>
and it will auto-complete the tag the same way it does for files and directories:
MyClass MyClassFactory ~$ vim -t MyC
I find this really useful when I'm jumping into a quick bug fix.
Comments
I've added a similar tip for ZSH.
I was very excited to see this, but I was very annoyed that it expected a tags file in the current directory. I keep a tags file at the root of each project, and vim -t is smart enough to find the correct tags file, so I wanted bash completion to be just as smart.
So, I modified the file a bit. It will now look for a tags file in the current directory, and then keep looking in parent directories until it finds one. (note: changed `pwd` to $PWD)
_vim_ctags() { local cur prev COMPREPLY=() cur="${COMP_WORDS[COMP_CWORD]}" prev="${COMP_WORDS[COMP_CWORD-1]}" case "${prev}" in -t) while [ "${PWD}" != "/" ]; do if [ -r ./tags ]; then # Escape slashes to avoid confusing awk cur=${cur////\\/} COMPREPLY=( $(compgen -W "`awk -v ORS=" " "/^${cur}/ { print \\$1 }" tags`" ) ) return fi cd .. done return ;; *) # Perform usual completion mode ;; esac } # Files matching this pattern are excluded excludelist='*.@(o|O|so|SO|so.!(conf)|SO.!(CONF)|a|A|rpm|RPM|deb|DEB|gif|GIF|jp?(e)g|JP?(E)G|mp3|MP3|mp?(e)g|MP?(E)G|avi|AVI|asf|ASF|ogg|OGG|class|CLASS)' complete -F _vim_ctags -f -X "${excludelist}" vi vim gvim rvim view rview rgvim rgview gview
Thanks for posting this.
Here is how I modified the completion function with tags-file search for my own .bashrc. I basically rewrote most of it, partly just for stylistic preference, but also to make some improvements:
- the upward directory search doesn't change the current directory, which is typically not a good idea in a shell function
- it uses grep instead of awk. grep is most likely faster, and the invocation is simpler
_vim_ctags() { local cur prev cur=${COMP_WORDS[COMP_CWORD]} prev=${COMP_WORDS[COMP_CWORD-1]} [[ $prev = -t ]] || return local tagsdir=$PWD while [[ "$tagsdir" && ! -f "$tagsdir/tags" ]]; do tagsdir=${tagsdir%/*} done [[ -f "$tagsdir/tags" ]] || return COMPREPLY=( $(grep -o "^$cur[^ ]*" "$tagsdir/tags" ) ) }
I haven't done extensive testing on it, but it works for me so far.
Note that there is an invisible tab character inside the grep pattern. --February 22, 2013
