💻Lisp Devs Stay Inside Their Programs, No Restart Needed

Lisp devs never leave their program process

TL;DR

Lisp programmers can edit live code without restarting, thanks to hot-swapping and a condition system. Haskell offers some improvements but lacks Lisp's live editing capabilities.

Lisp programmers can edit live code without restarting, thanks to hot-swapping and a condition system. This allows for immediate feedback and debugging within the program process. Haskell, while offering a powerful type system and fewer exceptions, lacks Lisp's live editing capabilities. With Haskell, tools like ghcid can watch for changes and run tests, but they don't support evaluating code in the running program's REPL. This workflow is ideal for computational methods and projects involving differential equations and non-linear dynamics.

Key Points

1

Lisp programmers edit live code without restarting, thanks to hot-swapping and a condition system.

2

Haskell's powerful type system leads to fewer exceptions but lacks live editing capabilities.

3

Ghcid watches for changes and runs tests, but doesn't support evaluating code in the running program's REPL.

4

Haskell's foreign-store library maintains process state even when code is replaced.

5

Ghcid reloads code, runs tests, and restarts the application without losing important state.

Why It Matters

If you're working on computational methods or projects involving differential equations and non-linear dynamics, Lisp's live editing capabilities can significantly speed up your workflow. Haskell offers some improvements but lacks the live editing that Lisp provides, making it less ideal for rapid prototyping and debugging.
