Completion of cd type functions?

Completion of cd type functions?

[G. Khalsa]

Hi,

I just switched from tcsh to zsh.

In tcsh I frequently defined aliases to cd directly to various directories and 
used completion to move further from these directories:

Example:

alias cxxsrc 'cd ~/development/source/cxx/\!*'
complete cxxsrc "p@1@D:$HOME/development/source/cxx@"

This way I can just type cxxsrc from anywhere and have it complete only with 
directories in $HOME/development/source/cxx.

Can I do this somehow in zsh (simply)?  This seems pretty basic (it isn't even a
FAQ) but I can't figure it out. I got it to sort of work using a function that 
invokes "find" but it is deadly slow.

As far as I understand it I create a function:
cxxsrc() { cd $HOME/development/source/cxx/$* }
but the completion part eludes me.

Unfortunately the lete2ctl script fails when I try to run it so I can't get all 
my nifty tcsh completions translated automatically.


Thanks

In zsh 3.1, you need

cxxsrc() { cd ~/development/source/cxx/$1; }
compctl -W ~/development/source/cxx -/ cxxsrc

In older versions it's harder, particularly to get subdirectories.
You need to write a completion function which sticks the appropriate
part in front of the word so far, lists the directories that are
there, then deletes the front part of the word again and returns the
result; plus it still doesn't work as a path since in lists you get
the whole word, not just the last part of the path.

The supplied version doesn't go down too well with recent versions of
perl.  There's a new version of lete2ctl for 3.1, which should appear
soon.  It doesn't handle the 'D' code since that doesn't appear in any
of the tcsh manuals I have access to.

Or just do:

cxx=$HOME/development/source/cxx/
compctl cd -g '*(-/)'

and then just do:

cd ~cxx/<TAB>

Note: this works with 3.0.x dont know about 3.1.x I would assume this
behaviour has not changed.
