#define in source code and #elif for conditional compilation
f#

Hello is there a way to make a #define in the source code itself? and with a value like for example "#define CONSTANT 2" ?

.

There is no way to do this in F#. You can specify --define on the command-line and use them e.g. in #if, but that's all.

Also what about #elif

No plans for these as yet.

Note that you can nest to get the same behavior as the posited #elif, e.g.

#if FOO
blah
#else
#if BAR
blah
#endif
#endif

Thanks I knew about the command line switch, but are there plans to allow it in code in a next version?
