typocomath
A final (?) prototype for a refactor of mathjs, culminating the picomath, pocomath, typomath series. Provides an extensible core with "fuzzy" types for its operations, that can at any time generate exact .d.ts file for its current state.
To build and run the prototype, run:
pnpm install
pnpm build-and-run
experiment
Have a look at the section under /src/experiment and /src/plugins:
src/plugins/typeInferPlugin.tsis the actual plugin- in
tsconfig.jsonwe configure TypeScript to run the plugin src/experiment/arithmeticInfer.tswith an example where we define__infer__- after running TypeScript: look at
build/experiment/arithmeticInfer.tswhere the__infer__string literal is replaced with the actual types
The idea
Create a TypeScript plugin which can replace a string literal like __infer__ in a typed-function definition:
typed('square', '__infer__', <T>(dep: { ... } => { ... })
with the actual types, something like:
typed('square', '{ deps: { multiply: (a: T, b: T) => T; }; return: (a: T) => T }', <T>(dep: { ... } => { ... })
(We can discuss what syntax we like most, this is just a POC)
How to run
pnpm build-and-run
