I have a software project that I'm attempting to write zsh completions for. After installing a package that provided a number of pre-made completions, I found they were put here:

/usr/share/zsh/site-functions

So I wrote my completion script, and threw it in there too. ...and was frustrated by failure. I've tried the following:

  1. Symlinking to the original script from the directory above.
  2. Putting a copy of the script directly into the directory above.
  3. Setting my login shell to zsh (instead of just switching to it from another shell)
  4. (Probably) all permutations of compinit and rehash.
  5. Dumbing-down my original script so that there's no way it could be wrong.
  6. Changing the contents of another script. The changes worked, so the directory is correct and zsh is detecting completions scripts there.

Here is the dumbed-down script:

#compdef aura _arguments -s \ '-V[Version!]' \ '-h[Helpppp]'

And the current contents of my .zshrc. I'm not normally a zsh user.

autoload -U compinit compinit zstyle ':completion:*' rehash true

Please and thank you for any insight you can give. What am I missing?

EDIT: Contents of /usr/share/zsh/site-functions is:

  • Is the script called _aura? What does echo $_comps[aura] show? Commented Dec 29, 2012 at 22:39
  • The script is called _aura, but echo $_comps[aura] returns an empty string. Commented Dec 29, 2012 at 23:10
  • What is the value of fpath? What is the content of /usr/share/zsh/site-functions (which by the way is not the proper place to install your script, /usr/share is reserved for the package manager, you should put your scripts under /usr/local or your home directory)? Are there *.zwc files around? Commented Dec 29, 2012 at 23:12
  • Thanks for helping. The contents of fpath are: /usr/share/zsh/site-functions and all directories under /usr/share/zsh/functions/. There were too many to type out. Commented Dec 29, 2012 at 23:29
  • And it doesn't seem as if there are any .zwc files anywhere. I put the contents of /usr/share/zsh/site-functions in the original post. Commented Dec 29, 2012 at 23:41

Here's what I think of that can go wrong.

The file containing the completion code must be in a directory listed in the fpath array. Ok. Note that you should not put your own files under /usr/share; zsh doesn't care, but your file could be deleted or overwritten by your operating system's package manager, and you're likely to forget to back it up, copy it to another machine, etc. You should put your own files under /usr/local if you want to make them available to all users on your system, and under your home directory if you just want them for your user. You can add a directory to fpath in your .zshrc (before calling compinit), e.g.

fpath=(~/lib/zsh $fpath)

The first line of the file must be #compdef followed by a space followed by one or more command names separated by spaces. Check that there aren't any stray characters there, in particular the file must have unix line endings (LF), not Windows line endings (CRLF — the stray CR might cause the command not to be picked up).

The compinit function creates a cache file the first time it runs, so as to be faster next time. This file is called ~/.zcompdump. It contains the association between command names and completion functions (e.g. aura _aura), not the code of the functions. You may need to regenerate it sometimes. In particular, if you change the #compdef line in an existing file, compinit won't re-read the file. As long as you don't pass -C to compinit, it will pick up new files, but you must get the #compdef line right before the next time you start zsh. If you didn't, delete the cache file (rm ~/.zcompdump) and start zsh (or more precisely run compinit) again.

  • Zapped my old .zcompdump and now it works! Thanks a ton @Gilles. Commented Dec 30, 2012 at 7:54
