Where to place zsh autocompletion script on Linux?

Let me try to help here.

I was trying something similar and this is how I was able to get it worked. Below solution has verified with oh-my-zsh on debian distro [ubuntu]

Problem

  > Your zsh isnt giving proper completion suggestions say [conda]
  > This is what you get when you type in # conda tab

Solution

1. Find the completion script

   one great location is https://github.com/clarketm/zsh-completions/tree/master/src

2. Download the file to completions folder [~/.oh-my-zsh/completions]

   wget https://raw.githubusercontent.com/clarketm/zsh-completions/master/src/_conda ~/.oh-my-zsh/completions
   

3. Make sure the completions folder is listed under $fpath

   print -l $fpath
   

   1. What if its not listed It should have normaly added with .oh-my-zsh.sh If not append below to ~/.oh-my-zsh/oh-my-zsh.sh

      # add a function path
      fpath=($ZSH/functions $ZSH/completions $fpath)
      

   2. source .zshrc

      source ~/.zshrc
      

4. Execute compinit this will build ~/.zcompdump file for the functions

   compinit
   

Troubleshooting

1. Due to conflicts the suggestions might not be shown try the following

   rm -f ~/.zcompdump; compinit
   # we are clearing the function dump stored by zsh, its safe zsh will rebuilt it.
   

2. Try source .zshrc

   source ~/.zshrc
   

3. Try loggin out and login

4. Check the mapping in ~/.zcompdump

   vi ~/.zcompdump
   

   search for conda

   [/conda]

   you should see as below

   'conda' '_conda'

Hope someone will find it useful, if so Happy to Help

I got this to work by adding cheat.zsh to the ~/.oh-my-zsh/plugins directory. Zsh checks to autoload functions on FPATH, so try:

echo $FPATH

and then either add to FPATH or move the file into a folder on the path.

This actually does a much better job of explaining it: https://unix.stackexchange.com/questions/33255/how-to-define-and-load-your-own-shell-function-in-zsh
