the (prepared) specification for how to parse command-line options
command-line options as parsed into a plist
Defines show-help-for-NAME, run-NAME, and NAME functions.
The ‘define-command’ macro may be used to simultaneously define the
following three functions which are useful for defining a function
which may be invoked from the command line. For example, the
following invocation of ‘define-command’ on FOO results in:
(define-command foo (noun verb &spec +command-line-spec+ &aux scratch)
"Usage: foo NOUN VERB [OPTIONS...]
Do VERB to NOUN according to OPTIONS."
#.(format nil "~%Built with ~a version ~a.~%"
(lisp-implementation-type)
(lisp-implementation-version))
(declare (verbose))
(when help (show-help-for-foo))
#|...implementation...|#)
show-help-for-FOO
: Prints help and option information for FOO to STDOUT.
The docstring passed to ‘define-command’ becomes the help text
printed before options. A second docstring passed as the fourth
argument to ‘define-command’ is printed after the options.
run-FOO
: This function is meant to be used as a ‘defsystem’ :ENTRY-POINT.
It runs FOO on the command line arguments by invoking
‘handle-command-line’.
FOO
: The &BODY passed to ‘define-command’ becomes the body of the FOO
function. The positional required command line arguments become
named arguments to FOO and the command line options passed in
behind the &SPEC keyword in the argument list become keyword
arguments to FOO.
The macro-expanded prototype for FOO in this example would be the
following (where all keyword arguments are option names from
+command-line-spec+).
(DEFUN FOO (NOUN VERB &KEY B CHECK VERBOSE WARN HELP VERSION &AUX SCRATCH))
SPECIFICATION is a list as described above.
COMMAND-LINE is the list of tokens to be parsed.
Return two values:
a list of alternating actions and values, and
a list of the arguments remaining after the various specified options.
Indicates the wrong number of arguments were given on the command line.
Given a STRING option argument and a TYPE of argument,
return the argument value as a Lisp object.
OPTION is the name of the option to which the argument is to be passed,
for the sake of error messages.
Remove all the options and values from *COMMAND-LINE-ARGUMENTS*. Process each option.
ARG is a string. Is it like –XXX ?
This is called for each option specification when preparing for parsing, and
computes the action function to call (with optional value if provided)
when the option is found on a command-line.
P is the hash-table of actions.
NAME is the first name of this option, a string or a character.
The keywords are option options for this option specification.
ARG is a string. Is it like +X ?
Given a SPECIFICATION, return a hash-table mapping
option names to a vector of
the action function to call when encountering the option,
the type of option arguments accepted, and
whether the option is optional.
ARG is a string. Is it like -X, but not – ?
