autocompletion of file url's

autocompletion of file url's

[Nathan Haigh]

I've started using subversion a bit recently and it annoys the hell out
of me when you have to specify repositories etc with file urls since
autocompletion doesn't work. e.g.

svn import tmp/myproject file:///path/to/my/svn/repo

i'd like to be able to type:

svn import tmp/myproject file:///p<tab>
to autocomplete to:
svn import tmp/myproject file:///path

and so on like this:

svn import tmp/myproject file:///path/t<tab>
completes to:
svn import tmp/myproject file:///path/to


I have no idea where to start with zshcompsys and writing
commands/functions to my .zshrc file, so any help would be much appreciated.

Kind regards
Nathan

It looks like the completion function is still not all that
sophisticated, so presumably no subversion user up to now has got to
grips with the nitty gritty.  Here's your chance to become a zsh
completion wizard...

The despatcher for subversion commands doesn't have an explicit entry
for "import", so it tries to synthesize it from the help text and
doesn't get it right.  This adds an explicit entry.  I'm guessing the
first argument will usually be a directory, but that can be changed if
not.  The URL completion for the second argument is standard across the
completion system and should be good enough for your purposes.

Say if you come across any more problems; I only use subversion very
occasionally (and the Perforce completion is a good deal more complete
:-)) but it's an important thing to get right.

I've added matching parentheses to the case statement because they
looked nicer.

See the zshcompsys manual page.  The simple way to start is
"autoload -U compinit; compinit".  The patch I posted is for the lastest
version of zsh; I've committed a change to the 4.2 branch to the archive.
You probably need at least 4.2.something for any half-way reasonable subversion
completion.

Once the system is installed as above, it will find completions for
subversion automatically.

Same answer.  There's just the single step for activating the entire
system.  There are lots of configuration options using "zstyle", however.

That's the wrong way to do it.  You're now going back to the old
"compctl"-based completion.  That has no subversion completion built into
it and you will be picking up whatever compctl instructions are around on
your system.  It's much harder to extend and in particular you're unlikely
ever to get URLs working properly.

Keep the lines above and check you have some version of zsh 4.2 or higher.
After running those lines, "print $_comps[svn]" should output
"_subversion".  That's the completion function I patched yesterday.

You should be able to use this instead:

zstyle ':completion:*' matcher-list 'm:{a-zA-Z}={A-Za-z}'
