https://issues.dlang.org/show_bug.cgi?id=19669 Issue ID: 19669 Summary: There is no way for code to detect whether -dip1000 is enabled or not Product: D Version: D2 Hardware: All OS: All Status: NEW Severity: major Priority: P1 Component: dmd Assignee: nobody@puremagic.com Reporter: monkeyworks12@hotmail.com Currently, there is no way for code to tell whether the -dip1000 switch has been passed to the compiler. This makes it harder to write code that needs to do something different depending on whether dip1000 is in effect or not, and in my opinion, is REQUIRED for any non-trivial code base that wants/has to support legacy compiler versions. There is a hacky workaround: static assert(!__traits(compiles, { char[] f() { char[2] x; return x[].splitterASCII!(_ => _ == ' ').front; } })); But it would be far preferable to be able to use `version(dip1000)` or `static if (dip1000)`. -- |
