COLANDER

Copyright (c) 2017 William Yao

Goals

• Generate parsing code from declarative specifications of CLI
• Generated code should have no dependencies other than CL itself
  • In other words, parsers are completely standalone; they don't even need this library
• Handle a wide range of syntaxes in use
  • long vs. short options
  • double dash --,
  • specifying an option's argument separately -b 20 vs. together -b=20
  • collapsed short options -iavh

• Be convenient to use
• Write beautiful code

Description and usage

Currently in a very preliminary state, but it works.

CL-USER> (defparameter parser
           (colander:cli-specs-to-parser%
            '("add" (:opts "-iavh") (:arg "-b" "BOUND") :filename)
            '("init" (:opt "-h") (:opt "-v"))))
PARSER

CL-USER> (colander:output-parser-to-file% parser "cli-parser.lisp")

;; <in "cli-parser.lisp">

(defun main (argv)
  (format t "~A~%" (colander-parser:parse argv)))
