You can: * Execute shell commands at compile-time * read file at compile-time * do computation at compile-time (be aware that this is done in a VM that is much slower than compiled-code and not suitable for CPU-intensive computation)
But what you want is basically a JIT. Here is an example JIT where I translate brainfuck programs to assembly: * [https://github.com/mratsim/jitterland/blob/master/bfVM_v03_jit.nim](https://github.com/mratsim/jitterland/blob/master/bfVM_v03_jit.nim) Alternatively you can just use an interpreter. Some inspiration in C/C++ * [https://github.com/codeplea/tinyexpr](https://github.com/codeplea/tinyexpr) * [https://github.com/zserge/expr](https://github.com/zserge/expr) Also I'm currently implementing a compiler for deep learning with SIMD support (and GPU and parallelism later). For now I'm only supporting compile-time code generation but later I will also add runtime code generation, probably via LLVM JIT capabilities: [https://github.com/mratsim/compute-graph-optim](https://github.com/mratsim/compute-graph-optim)
