Usage ===== Adopt is a simple library for parsing UNIX-style command line arguments in Common Lisp. It was made because none of the other libraries did what I needed. [TOC] Package ------- All core Adopt functions and macros are in the `adopt` package. You can `:use` that if you really want to, but it's probably clearer to use namespaced `adopt:…` symbols. Interfaces ---------- define-interface and usage. nothing else. Parsing ------- `parse-options` with a bare-bones interface. Options ------- talk about the option arguments. Short and Long Options ---------------------- short versus long arguments. 1+ is required. Initial Value ------------- at this point it's just a default Reduce ------ talk about reducers. mention argparse's: `store_const` is `(constantly x)` `store` is `#'latest` `store_true` is `(constantly t)` `store_false` is `(constantly nil)` `append` is `append1` `append_const` is `(rcurry #'append1 x)` `count` is `1+` with an `initial-value` of `0`. need to figure out `help` and `version`. Usage Printing -------------- It's `(print-usage interface)`.
