Parse-demo2-opts-long

Signature

(parse-demo2-opts-long getopt::longname getopt::explicit-val 
                       args getopt::acc getopt::seen) 
 
  → 
(mv getopt::errmsg getopt::acc rest)

Arguments

getopt::longname — Longname we've just found, e.g., "foo" if we've just seen --foo=bar.
    Guard (stringp getopt::longname).

getopt::explicit-val — Any explicit value passed to this option, e.g., "bar" if we've just seen --foo=bar, or NIL if we've just seen --foo.
    Guard (or (not getopt::explicit-val) (stringp getopt::explicit-val)).

args — Remaining arguments past longname.
    Guard (string-listp args).

getopt::acc — Structure we're updating.
    Guard (demo2-opts-p getopt::acc).

getopt::seen — List of longnames that we've seen so far.
    Guard (string-listp getopt::seen).

Returns

getopt::errmsg — NIL on success or an error message.

getopt::acc — Updated structure.
    Type (demo2-opts-p getopt::acc), given (force (demo2-opts-p getopt::acc)).

rest — Rest after this one.
    Type (string-listp rest), given (force (string-listp args)).
