I would like to do completion from a list of values that have ':' in 
them, something like:

_values foo a::b c::d

and have it offer 'a::b' and 'c::d' as choices, but I can't figure out 
how to escape the ':' in the completion system.

Thanks,
Scott

Backslashes:

[[[
% _f() { _values desc 'foo\:\:FOO' 'bar\:\:BAR' } 
% f <TAB>
> desc
bar::BAR  foo::FOO
% 
]]]

Cheers,

Daniel

Or don't use _values:

  _wanted foos expl foo compadd a::b c::d

Which particular feature of _values do you want? For lists, you can use
_sequence, e.g.:
  _wanted foos expl foo _sequence compadd - a::b c::d

and if you want descriptions, _describe might do the job but probably
still needs colons to be quoted. _values is usually not the best choice
when the list of matches are generated somehow.

Thanks, I thought I had tried all combinations of quotes and backslashes 
but apparently not.

I guess I don't know which is most appropriate, there are many options 
and _values seemed to fit the bill.

I pared things down for my question, but to be more exact I want 
completion for an option.  Something like:

_arguments : '--foo[Which foo to use]:foo:_values whatever 'a\:\:b' 'c\:\:d'

i.e. the --foo option has a limited number of legal values.  What would 
you suggest I use here?

If you're using _arguments you can just do like:

  '--foo[specify foo to use]:foo:(a\:\:b c\:\:d)'

You can also use this syntax to give each value a description:

  '--foo[specify foo to use]:foo:((
    a\\\:\\\:b\:"ab foo"
    c\\\:\\\:d\:"cd foo"
  ))'

Though it gets somewhat confusing when you have colons in the values, as you
can see
