completion after --

completion after --

[Erik Toubro Nielsen]

Assume a command line, where the option --files mean that at least one
filename can be given after '--'

   cmd --files --other-options  ARG1 -- filenames...

(without --files the command line is
   cmd --other-options  ARG1 
)

The _arguments function does not seem applicable.

Any hints on how to write a completion function _cmd for this?

_arguments is applicable but it isn't sufficient on it's own.

Check for --files and -- before calling _arguments:

local -a args
if (( ${+words[(r)--files]} && ${+words[(r)--]} && words[(i)--] < CURRENT ))
then
  _wanted files expl file _files
else
  _arguments '--files' '--other-options' ':arg1:(ARG1)'
fi

That also checks that the `--' is before the cursor.
