ridiculousfish	e0e4b11dbd	Make arguments to builtins const ... Prior to this change, builtins would take their arguments as `wchar_t **`. This implies that the order of the arguments may be changed (which is true, `wgetopter` does so) but also that the strings themselves may be changed, which no builtin should do. Switch them all to take `const wchar_t **` instead: now the arguments may be rearranged but their contents may no longer be modified.	2021-03-28 15:31:25 -07:00

Kurtis Rader	277999adef	implement argparse builtin ... We've needed a fishy way to parse flags and arguments given to scripts and functions for a very long time. In particular a manner that provides the same behavior implemented by builtin commands. The long term goal is to support DocOpt. But since it is unclear when that will happen so this implements a `argparse` command. So named as homage to the excellent Python module of the same name. Fixes #4190	2017-07-12 22:38:24 -07:00
