Eshell pccomplete support for drush

[dhaley]

Hi, I just read this great post on getting Eshell's pccomplete working with git:

http://tsdh.wordpress.com/2013/05/31/eshell-completion-for-git-bzr-and-hg/

It seem like it would be great to add this same support for drush in Eshell. Drush already works great for me in Eshell with the exception that I haven't been able to display ansi colors.

It seems that it would be easy at drupal-mode init to run 'drush help' and then store the various options in pcmpl-git-commands.

I might try to take a stab at this with my rudimentary elisp, but it seems like this autocompletion of drush should be available to all emacs Drupal folks.

I got this working. Here is the code:

It would be cool to see this somehow put in drupal-mode.

Got it working much better here:

I'm using drush 5.9.

It even pulls in site aliases. But for some reason I can't get the site aliases that begin with @ to expand like the commands do. It's using running the same drush command that drush bash completion script uses:

Good idea!

I changed it slightly to better fit in with the general naming of functions and variables in drupal-mode.

Committed in ae4dd40.

I can't get it to complete on site aliases either. I guess some other pcomplete stuff is messing around. But this is still way better than without it.

The site alias completion does work in shell (shell-mode).

@arnested, When do you anticipate a new release of drupal-mode that will have the new stuff in the 'develop' branch?

[arnested]

Oh, it does work in shell but not in eshell. Weird. But better :-)

I have been wanting to do a new release for quite some time. But I really would like to fix #12 first. It annoys me a lot but requires quite some rewriting of the detect version/rootdir functionality. I'll better try to prioritize it then...

The version in MELPA is fresh from the develop branch and includes the pcomplete support.
