Access to Xojo compiler version at runtime.

General
1

Anyone know of a way to access at runtime or build time the version number (2018r3 et al) of the IDE compiler being used to compile your Xojo program?

2

The constant RBVersion contains the version number of the IDE.

#if RBVersion < 2018 then
    // don't use newest features
#endif
3

XojoVersion for evaluation and XojoVersionString for display.

Great! Is there a way to use this info at compile time to set a constant of a simpler name that can then be used globally in an abbreviated form at compile time?

#if RBVersion > 2018.03 AND TargetMacOS AND Target64Bit Then
const isModern = true
#EndIf

#If isModern Then
// Do something more clever
#Endif

Perhaps in some kind of pre-compile script?

how much more abbreviate do you want?

dim s as string=RBVersionString  // RBVersionString
dim v as double=RBVersion

doesn’t need to be used in a #IF statement

Or you could use much the same code in a IDE script that executes before the build step. That script can set a constant in your app then you can just test that constant. The code you posted can, and does, work but it needs to set a global constant (on App for instance) and you can do that with the style of code you’ve posted.
