With a static check this will never happen anymore to anyone. Forgot to say that the only way to handle "h" should be the getopt results, e.g void main(string[] args) { import std.getopt; auto h = getopt(args, config.passThrough); if (h.helpWanted) {} } That's why it can be rejected at compile time. -- |

Simplified test case: /////////////// test.d /////////////// void main() { import std.getopt; string[] args = ["program", "-h"]; getopt(args, config.passThrough); assert(args == ["program", "-h"]); } ////////////////////////////////////// Introduced in https://github.com/dlang/phobos/pull/2072 (In reply to b2.temp from comment #1) > @Alexandru, I think that the best fix is to > > 1/ add a static assert() that prevents to specify "-h" or "--help" (for > example there's already "optionValidator" that does a few static checks) What if I want to generate my own help screen? E.g. if I'm using a library around std.getopt that generates its own enhanced help screen (e.g. ae.utils.funopt). -- |

https://issues.dlang.org/show_bug.cgi?id=16684 --- Comment #5 from Vladimir Panteleev <dlang-bugzilla@thecybershadow.net> --- (In reply to b2.temp from comment #2) > Forgot to say that the only way to handle "h" should be the getopt results, e.g I guess "helpWanted" is a way to do that, but this was still a breaking change. Also, I don't think the check can be done at compile-time, since the argument list to getopt consists of regular runtime arguments, so I don't think you can get the switch string literals at compile-time (from within getopt) here. -- |
