Issue #7537 has been updated by prijutme4ty (Ilya Vorontsov). In my opinion, negative numbers shouldn't be treated as option keys unless it was explicitly specified. In other cases them should be treated as usual parameters. ---------------------------------------- Bug #7537: OptionParser treats negative digits as options https://bugs.ruby-lang.org/issues/7537#change-34562 Author: prijutme4ty (Ilya Vorontsov) Status: Open Priority: Normal Assignee: Category: Target version: ruby -v: 1.9.3(p0, p327 both) Is it intentional that negative digits are treated as options?

Issue #7537 has been updated by prijutme4ty (Ilya Vorontsov). Sent a pull-request. https://github.com/ruby/ruby/pull/259 I've made changes the same way as python do -- http://docs.python.org/dev/library/argparse.html#a... This patch introduces one possible (but not very serious and very rare) incompatibility: if one already uses explicitly defined negative-digit option such as '-1' and also uses an option with optional argument '-p [ARG]' and runs a command with options '-p -1' then before patch it'll be treated as two different options '-p', '-1' and after patch they are treated as an option '-p' with value '-1'. If one meets this problem, he can use option declaration with equal sign: '-p=[ARG]' or just change places of arguments and run his program with options '-1 -p'. But I suppose not too many people use explicitly defined numeric options and even less people use optional argument with them in such order (may be even nobody use it such a way). ---------------------------------------- Bug #7537: OptionParser treats negative digits as options https://bugs.ruby-lang.org/issues/7537#change-37695 Author: prijutme4ty (Ilya Vorontsov) Status: Assigned Priority: Normal Assignee: nobu (Nobuyoshi Nakada) Category: lib Target version: ruby -v: 1.9.3(p0, p327 both) Is it intentional that negative digits are treated as options?
