Complete with *part* not part*

Complete with *part* not part*

[Sebastian Gniazdowski]

Hello,
when completing, entering "l"<TAB> will complete say "ls", "lsof",
etc.. How to make "s"<TAB> complete ls, lsof, etc. ?

I'm completing long names – names of plugins:
            plugins=( "$ZPLG_PLUGINS_DIR"/*(N:t) )
            _wanted plugins expl "Plugins" \
                compadd "$@" -a - plugins && ret=0

want it be that "part" of plugin names will be completed not only as
part* but also as *part*.

Best regards,
Sebastian Gniazdowski

That's something the user configures, not something you put in the
completer. (Which they do with the matcher-list style).

Which you do like this:

    zstyle ':completion:*' matcher-list 'r:|=** l:|=*'

This works.

Want to have this only for "zplugin" and only for its sub-command.
Tried various combinations and none work. Already have working:

zstyle ':completion:*:zplugin:*:argument-rest' list-colors
'=(#b)(*)/(*)==1;35=1;33'

But doing the same or trying more "::" or ":*:" doesn't yield correct
behavior. Ctrl-x h is:

% zplugin load <^x h>
tags in context :completion::complete:zplugin::
    argument-rest  (_arguments _zplugin)

I'm using "_arguments" not "_arguments -C".

Anyway thanks, there for sure is some correct "::" ":*:" sequence for
this to work...

The name is "matcher" when it's a specific tag, "matcher-list" is for
the global setting.  So this should theoretically do it:

zstyle ':completion:*:zplugin:*:argument-rest' matcher 'r:|=** l:|=*'

Looked at the dtrace output and found this to work:
zstyle ':completion::complete:zplugin::plugins' matcher 'r:|=** l:|=*'

Fine thing the dtrace, huh. I think it reveals some bugs in my
completion design. Should I be using -C for _arguments? Because there
are tests that look bad, double "argument-rest":

Zstyle -s :completion::complete:zplugin:argument-rest:argument-rest
matcher match

No, nothing is wrong there.  Remember that the lookup context is of
the format

    :completion:FUNCTION:COMPLETER:COMMAND:ARGUMENT:TAG

So you have COMMAND=zplugin, ARGUMENT=argument-rest, TAG=argument-rest,
which is entirely normal:

   * The ARGUMENT; this indicates which command line or option argument
     we are completing.  For command arguments this generally takes the
     form argument-N, where N is the number of the argument, and for
     arguments to options the form option-OPT-N where N is the number
     of the argument to option OPT.  However, this is only the case if
     the command line is parsed with standard UNIX-style options and
     arguments, so many completions do not set this.

The doc omits the detail that N can be "rest" when all remaining argument
positions are treated the same.

   * The TAG.  As described previously, tags are used to discriminate
     between the types of matches a completion function can generate in
     a certain context.

So you only want -C if there are multiple tags in the argument-rest
context, *and* those tags are differentiated by using the ->state
form of _arguments specification.

The doc goes on:

 The context is gradually put together as the functions are executed,
 starting with the main entry point, which adds :completion: and the
 FUNCTION element if necessary.  The completer then adds the COMPLETER
 element.  The contextual completion adds the COMMAND and ARGUMENT
 options.  Finally, the TAG is added when the types of completion are
 known.

The tag name is actually generated by the "comparguments" builtin in this
case, which was intentionally left under-specified in the user-level doc,
but then developer-level doc for it was never written ...

I used zplugin/dtrace to catch all zstyle calls performed after
"zplugin load go<TAB>":

https://asciinema.org/a/birc08xq4qa2cbl9zcwvlxvho

I attach the dtrace report. Interesting, there is only:

Zstyle -a :completion::expand::: matcher-list _matchers
Zstyle -a :completion::complete::: matcher-list _matchers
Zstyle -s :completion::complete:zplugin:argument-rest:argument-rest
matcher match
Zstyle -s :completion::complete:zplugin::plugins matcher match
Zstyle -a :completion::ignored::: matcher-list _matchers

There isn't something analogous to list-colors zstyle:

Zstyle -a :completion::complete:zplugin:argument-rest:argument-rest
list-colors val

Will I be able to target the matcher-list zstyle at
":completion::complete:zplugin:argument-rest:" if there is no test for
this zstyle during operations triggered by <TAB>?
