Retrofitting a build system into a compiler
TL;DR
Lucas Ma is exploring the integration of effects into the OCaml compiler, aiming to transform it into a long-lived compiler service. This effort addresses challenges posed by OCaml's legacy codebase designed for single-shot compilation.
✦ Why It Matters
Consider exploring effects in your own projects to enhance compiler functionality and service longevity.
Key Takeaways
- Explore using effects for dynamic module compilation in OCaml.
- Utilize the snapshot mechanism to manage global state during compilation.
- Implement parallel compilation to enhance build efficiency.
- Transition from traditional build systems to the new simplified approach.
How It Works
The integration of effects allows the OCaml compiler to dynamically compile modules as needed, rather than requiring all dependencies to be pre-compiled. This is achieved by taking snapshots of the compiler's global state before performing lookups for missing files, enabling the compiler to resume its previous state after compiling the required modules.
Additionally, the use of multiple domains allows for parallel compilation, where each domain can handle different modules simultaneously, significantly speeding up the build process.
