The problem I have with this is that it uses an option. In 3.1. I
would like to make the code in `zle_tricky.c' use a pointer variable to
call `listmatches()' to allow stuff like this to be put in a different
module that may be loaded on top of `compctl'. We can then also add a
different colourisation module which is a bit more zsh-ish. Probably
using a assoc array to map patterns/descriptions to strings like
`%B%n%b' where the `%n' gets replaced by the string (of course, the
best way would be to allow different maps for different completions,
but we could already use group names for that). Or something like
that. This should be easy to use because I think that sometime we will
be able to make modules autoloaded on parameter names (haven't really
looked for that in the code yet, but every parameter name lookup goes
through the paramtab-hashtable functions, right?).
Of course, if we add a way to allow modules to define options and make
modules autoloaded on them, nothing could be said against using a option
for it (well, something could be said against it: it's superfluous --
even in your patch making it use only `ZLS_COLOR' (or turning it into
an array and giving it a better name) and testing if that is set would
Anyway, I don't think that I'll ever use a feature like this and so
would be against putting it into the zsh core itself. But it's not my
duty to decide this...
P.S.: Module-defined options may also be an argument for moving to a
assoc array based option system.
