"include" equivalent in propeller tool ?

bdickens

I'm working on an application that has a lot of common code blocks. Ultimately, we will have 5 separate props running variations of the same program. But I'm getting exhausted making changes in all 5 every time I "fix" a chunk of code that is in all 5.

And sooner or later, I will screw up.

is there an equivalent to the //include command that will pull source code in ?

The "OBJ" blocks come in and can't reference my variables directly and I'm even worse at the @, @@ stuff. Yes, I'm lazy but I've accidentally changed the code a couple of times, lost the change in the next copy / paste.

Thanks

Alas, there's no equivalent to an include statement. There is a FILE statement, but it includes a binary file which isn't what you want.

It is possible to use "objects" to do something like what you want. You can have an object with little or no local storage, but with constants and methods, all of which can be referenced outside of the object and then refer to this object from several other objects in your program. The compiler will detect that all these object instances use the same code and use only one copy of the binary code. Some of the FemtoBasic versions use this technique for program-wide global constants (look at DongleBasic or BoeBotBasic in the Object Exchange).

Another option, depending on what you're trying to do, would be to use BST's conditional compilation

You could use a macro-processor, like m4. I often use it with software that lacks some feature like that, or to add macros to an assembler.

You can follow Mike Green's advice even for code blocks that have storage if you use DAT instead of VAR for your storage. If you have multiple instances of an object they each get their own VARs, but they all share one DAT. This makes it possible to make such an object "global" within the application by including it under all the other objects, and such an object is a separate file that can be shared between different applications.

It's still a PITA but it's a workaround.

Ahhh. That'll work. Thanks for the suggestions everyone.

Sounds like bst would be your best bet. This has conditional compiles with #define & #ifdef.
