Zsh completion configuration with history-words as another group to _complete

Zsh completion configuration with history-words as another group to _complete

[joe M]

Hello,

I am trying to figure out how to add "history-words" as a group within
_complete, similar to aliases or functions.

zstyle -e ':completion:*' completer \
   'compprefuncs=(_history_word_list) reply=(_complete _match
_approximate _ignored _prefix)'

cat /usr/share/zshcat
/usr/share/zsh/5.0.2/functions/Completion/Base/_history_word_list
#autoload
_history "$@"
return 0/5.0.2/functions/Completion/Base/_history_word_list
#autoload
_history "$@"
return 0

The list of history-words show up along with any other groups shown by
_complete or any of the completers in "reply". But, unfortunately, it
does not execute the matched word with one Enter keypress. I need to
press Enter twice for the history word to be used.

I am not sure if the above is the correct approach to this issue, or,
if I should be looking at changing _complete to add the
_history_words_list as a tag within the  _complete function instead.

Any thoughts, please?

Thanks
Joe

if I change /usr/share/zsh/5.0.2/functions/Completion/Zsh/_command_names,
by changing the below lines to:

defs=(
  'commands:external command:_path_commands'
)

to

defs=(
 'history:history words:_history_complete_word'
  'commands:external command:_path_commands'
)

It seems to work. Being a newbie, I am not sure if this is a reliable
approach. Any thoughts, please?

Thanks
Joe

I'm now regretting having mentioned compprefuncs in that thread last
month.  Really, just don't mess with it unless you know exactly why
you need it.

That's probably because _history is adding so many matches that a menu
is always being invoked.

I think my previous response covers this ...

(BTW, zsh-workers see all zsh-users postings, no need to copy both lists.)

As a general rule, if you (a) describe yourself as a newbie and (b) find
yourself re-hardwiring one of the default functions, you're probably on
the wrong track. :-)
