Hi,

Currently,

$ gdc-12 --version
gdc-12 (Ubuntu 12.1.0-2ubuntu1~22.04) 12.1.0

$ gdc-12 -dumpversion
12

this is not very informative, as D (DMD) language is always changing, Can gdc --version or -dumpversion output the corresponding DMD front-end (language) version?

just as LDC does:

$ ldc2 --version
LDC - the LLVM D compiler (1.32.2):
  based on DMD v2.102.2 and LLVM 15.0.7

I don't think it's possible because --version and -dumpversion are common throughout GCC.

To get the version just compile a file with the content:
pragma(msg, VERSION);
