Compiler flags only work per project. If you have more than one project in one
directory - use name of file as a name of config to set different flags for
each of them.
Here `first.nim` and `second.nim` \- are two separate projects:
first.nim
first.nims # config for `first`
second.nim
second.nims # config for `second`
config.nims # config for both `first` and `second`
Run
If you try to compile `second.nim`, you should see hints telling you which
config files are active:
$ nim c second.nim
Hint: used config file '/.../config.nims' [Conf]
Hint: used config file '/.../second.nims' [Conf]
...
Run
Or, maybe, you're trying to set different compiler flags for two files that
will compile to a single executable? As far as I know - it's not possible.
