Feasibility of multi-executable architecture for a large application using Crystal

[kojix2]

The short answer is NO.
Please read the conversation between Ary Borenszweig and Beta Ziliani.

Embeddable / Interoperable with ruby

Let’s take this code: def foo(x) if x.is_a?(Int32) 1 else 2 end end foo(1 || 'a') foo('a' || 1) We can compile it like this: crystal build --prelude=empty --emit llvm-ir foo.cr That will give us the LLVM IR for that file, and specifically for what the generated foo function is. How does the generated code check if x.is_a?(Int32)? The answer is that Crystal gives each type a unique ID: an integer. Here’s the LLVM IR code for the generated foo function: define internal i32 @"…

Incremental compilation exploration

Happy new year! I believe that, at some point, incremental compilation will have to be introduced to Crystal in order for it to keep growing. I started exploring this problem, just a bit. I wrote a blog post about it: Incremental compilation for Crystal - Part 1 - DEV Community
