autocomplete aliased 'emerge' command in zsh [Solved]

[ppurka]

I have the following command (using cfg-update here) aliased to emerge in my ~/.zshrc

Code: Select all

alias emerge='emerge_with_indexing_for_cfg-update'

However, whenever I try to autocomplete the options of emerge or package names (as usual, by typing <tab> after a half-complete name/option), the autocomplete does not work. I think zsh internally expands the emerge command to its actual command and so does not find any autocompletions for that actual command.

Is there a way of disabling this "internally_replace_the_alias_by_its_command" only for the 'emerge' alias? FYI, the autocomplete works fine in bash (so bash obviously does not internally replace the alias name by the actual command).

TIA.

Hi ppurka, try this easy test:

Code: Select all

% alias emerge="myemerge"
% setopt complete_aliases
% emerge -<TAB>        # press <TAB> in order to autocomplete

When I press <TAB> zsh shows the list of options as if emerge was not an alias.
From "man zshall":

COMPLETE_ALIASES
Prevents aliases on the command line from being internally substituted before completion is
attempted. The effect is to make the alias a distinct command for completion purposes.

Excellent! It works. The command is (without the underscore) :

Code: Select all

setopt completealiases

Thank you!

With or without the underscore makes no difference . From the great zshoptions man pages:

SPECIFYING OPTIONS
Options are primarily referred to by name. These names are case insensitive and
underscores are ignored. For example, `allexport' is equivalent to `A__lleXP_ort'.

I didn't know about this property of zsh that you have mentioned. I just used the superb autocompletion of zsh to complete my setopt command, and it spit out completealiases, without the underscore.

The more I use zsh, the more I love this shell

Yeah, I like it too, very powerful. It's a pity that it's not widely known. At now I use Bash only for those (few) scripts I publish online.
If you're interested, I've put my zsh dot-files on my web site.

Thanks. Those dot-files are heavily customized! I haven't been able to look completely into the power of zsh yet. I had created a .zshrc more than a year back, and I have not done any modificiation to it since. Some day when I have ample time, I will study your dot-files

Thanks for sharing
I didn't change my config since a long time and these custom files will help me improve my zsh usage !!!
