zsh-completions require compinit in the .zshrc file?

[daften]

Is that necessary, after changing the fpath?

Adding the line in changing the fpath at the beginning also helps.
Oh-my-zsh later performs compinit anyway

I find that i need to put the fpath modification like this:

fpath=(
  /usr/local/share/zsh-completions
  /usr/local/share/zsh/site-functions
  $fpath
)

source $ZSH/oh-my-zsh.sh

# User configuration

wondering if there's more location-independent way of doing this. Was hoping that I can put it below that user configuration line.

I finish install oh-my-zsh, then i add

fpath=(/usr/local/share/zsh/zsh-completions/src $fpath)

to .zshrc at the beginning, but it still doesn't work,
i must compinit in every zsh, then it can work.

who can tell me what's the problom ?

quote from brew info zsh-completions:

You may also need to force rebuild zcompdump:

rm -f ~/.zcompdump; compinit

HTH

hi, gilbertwyw,
i must compinit in every zsh, then it can work. means i do it like you say,
i saw the tips via manual installation before.

my system is ubuntu 14.04.

Yes, you need to call compinit in your .zshrc so it is run every time the shell starts. That is how zsh initializes the completion system; it is normal.

Sorry, disregard my last comment: I didn't see that some of you were running Oh My Zsh. OMZ calls compinit for you as part of the startup process, so you don't have to do it yourself.

The issue with OMZ and compinit here is (at least partly) that OMZ expects a different plugin structure than zsh-completions has. OMZ expects the definitions for all completion definitions to be in the root directory of the plugin. Its startup process goes like this:

• Add the root dir of each plugin to $fpath
• Run compinit
• Source each of the plugins' <foo>.plugin.zsh files to load them

Since zsh-completion uses zsh-completion.plugin.zsh to put its src/ dir on $fpath, it doesn't happen until OMZ has already run compinit, so its completions aren't included. You can do another compinit after sourcing ~/.oh-my-zsh/oh-my-zsh.sh to pick them up. However, multiple compinits could be a performance issue, and could break completions from plugins which define them explicitly using compdef and similar commands, instead of auto-loaded _name completion definitions.

add this to your .zshrc then source it:

rm -f "$HOME/.zcompdump"; compinit
source ~/.zshrc

problem solved

fpath=(/usr/local/share/zsh-completions $fpath)
rm -f "$HOME/.zcompdump"; compinit
source ~/.zshrc

Causes zsh to stuck on startup.

fpath=(/usr/local/share/zsh-completions $fpath)
rm -f "$HOME/.zcompdump"; compinit

Fixed the issue.
