https://issues.dlang.org/show_bug.cgi?id=20459 Issue ID: 20459 Summary: Runtime arg parsing should stop at '--' Product: D Version: D2 Hardware: All OS: All Status: NEW Severity: normal Priority: P1 Component: druntime Assignee: nobody puremagic.com Reporter: pro.mathias.lang gmail.com Currently runtime argument parsing (--DRT-gcopt for example) does not stop at the POSIX-recommended value (double dash, '--'). There is a way to disable argument parsing completely (https://github.com/dlang/druntime/pull/2375) but no way to write a program that would take arguments that are passed to a child, like `dub` or `rdmd` do. The three possible cases, using dub as an example, are: - dub --DRT-gcopt:whatever -- ProgramArguments (Configure dub) - dub -- --DRT-gcopt:whatever ProgramArguments (Configure the package) - dub --DRT-gcopt:whatever -- --DRT-gcopt:whatever ProgramArguments (Configure both) Note that this approach isn't fully perfect: It assumes the program will use `--` itself, which might not be true, but it's an improvement over what we currently have. Another option I could see is to provide a hook for argument parsing to programs instead of adding those booleans (rt_cmdline_enabled, rt_envvars_enabled, etc...). --
