Implementation of a pre-processor about brain HOT 9 CLOSED

from brain.

Which cases you think pre-processing can be really necessary & useful with brainfuck?

from brain.

@ryukinix using macros to have the possibility to "extend" the language/ make repetitive tasks easier

from brain.

Macros are really nice, but how you wish implement this? C-like syntax with #define ?

from brain.

Yeah, C-style(ish) macro...
I imagine that we can do that by using pipes.
Example:

| +++++ |

Each pipe would have a number related to it... Inside the code we would call the macros like:

+ make number 1 because is the first macro
^ call macro

In this case we would need two more operators | and ^, which is bad. Do you have pros and cons?

from brain.

@ryukinix I was thinking of changing a bit the code above... What if it was like that?

| number_five +++++ |
| arithmetic.brain |

In the first case, I'm creating a macro called number_five, in the second case, I'm including a file. What do you think? In this case we only need the operator pipe |

from brain.

Discussing about this feature with @luizperes in a call was revealing, while this is a nice idea it brings a bit of complexity to Brain (As it was not complex enough [literal joke here]), adding operators expands the range of errors that we could possibly get. That's one of the drawbacks, we just have to study carefully when and how to implement this great feature!

@ryukinix @rafaelcn Thinking and re-thinking, I realized that what @rafaelcn made so much sense. We should not add more complexity (more than planned) on Brain. As we want to use this language to solve AI problems as well, I do not think that we should add this new layer of complexity. Well, pointed @rafaelcn .

Anyone is welcome to re-open this discussion.
