Related to #58 Related to #30 Improve support for overloaded functions (up to 10 overloads). So for an example function type: ```ts type Factorize = { (input: number): number[] (input: bigint): bigint[] } ``` --- `.parameters` gives you an ExpectTypeOf instance with a union of the parameter-tuple types, so: ```ts expectTypeOf<Factorize>().parameters.toEqualTypeOf<[number] | [bigint]>() ``` --- `.returns` gives you an ExpectTypeOf instance with a union of the return types, so ```ts expectTypeOf<Factorize>().returns.toEqualTypeOf<number[] | bigint[]>() ``` --- `.toBeCallableWith(...)` now accepts any overload input, not just the "last" like before. And you can now chain it via `.returns` which gives you the matching return type: ```ts expectTypeOf<Factorize>().toBeCallableWith(5).returns.toEqualTypeOf<number[]>() ``` --- ## Implementation - overload utilities were added - initially, I thought all that was needed was a utility that matches `F` typeargs against a single 10-overload type - but the `test-types` job caught that this _doesn't_ work for typescript <5.3 - for lower typescript versions, it seems we need an approach more like the one in #58 - there are some edge cases the tests found for generic functions and parameterless functions, so there is _sometimes_ some "useless" overload info that has to be explicitly excluded - there are a couple of intermediate utilities to check if the 10-overload type can be used, and to exclude "useless" overloads - equivalents added for constructor parameters too - used the overloaded versions in `DeepBrand` too <details> <summary>update: moved these changes to #93 to reduce diff</summary> - I felt the megafile `index.ts` was finally getting too big with the added overload utilties: - so those were put in a new `overloads.ts` - since overload utils they rely on some other existing utils, I created `utils.ts` to avoid circular references - `index.ts` remains as the home for the main `ExpectTypeOf` exports - added `export * from './utils'` since we have been exporting all the internal utils and I don't want to break people - update: moved these changes to #93 to reduce diff </details> --------- Co-authored-by: Misha Kaletsky <[email protected]> Co-authored-by: autofix-ci[bot] <114827586+autofix-ci[bot]@users.noreply.github.com> Co-authored-by: Arya Emami <[email protected]>

##### [`v0.20.0](https://github.com/mmkal/expect-type/releases/tag/v0.20.0) #### Breaking changes - improve overloads support, attempt 2 by [@mmkal](https://github.com/mmkal) in mmkal/expect-type#83 This change updates how overloaded functions are treated. Now, `.parameters` gives you a *union* of the parameter-tuples that a function can take. For example, given the following type: ```ts type Factorize = { (input: number): number[] (input: bigint): bigint[] } ``` Behvaiour before: ```ts expectTypeOf<Factorize>().parameters.toEqualTypeOf<[bigint]>() ``` Behaviour now: ```ts expectTypeOf<Factorize>().parameters.toEqualTypeOf<[number] | [bigint]>() ``` There were similar changes for `.returns`, `.parameter(...)`, and `.toBeCallableWith`. Also, overloaded functions are now differentiated properly when using `.branded.toEqualTypeOf` (this was a bug that it seems nobody found). See [#83](mmkal/expect-type#83) for more details or look at the updated docs (including a new section called "[Overloaded functions](https://github.com/mmkal/expect-type#overloaded-functions)", which has more info on how this behaviour differs for TypeScript versions before 5.3). #### What's Changed - Fix rendering issue in readme by [@mrazauskas](https://github.com/mrazauskas) in mmkal/expect-type#69 - Fix minor issues in docs by [@aryaemami59](https://github.com/aryaemami59) in mmkal/expect-type#91 - create utils file by [@mmkal](https://github.com/mmkal) in mmkal/expect-type#93 - branding.ts and messages.ts by [@mmkal](https://github.com/mmkal) in mmkal/expect-type#95 - improve overloads support, attempt 2 by [@mmkal](https://github.com/mmkal) in mmkal/expect-type#83 - Extends: explain myself [`1e37116`](mmkal/expect-type@1e37116) - Mark internal APIs with `@internal` JSDoc tag ([#104](mmkal/expect-type#104)) [`4c40b07`](mmkal/expect-type@4c40b07) - Re-export everything in `overloads.ts` file ([#107](mmkal/expect-type#107)) [`5ee0181`](mmkal/expect-type@5ee0181) - JSDoc improvements ([#100](mmkal/expect-type#100)) [`0bbeffa`](mmkal/expect-type@0bbeffa) **Full Changelog**: mmkal/expect-type@v0.19.0...v0.20.0

##### [`v0.20.0](https://github.com/mmkal/expect-type/releases/tag/v0.20.0) #### Breaking changes - improve overloads support, attempt 2 by [@mmkal](https://github.com/mmkal) in mmkal/expect-type#83 This change updates how overloaded functions are treated. Now, `.parameters` gives you a *union* of the parameter-tuples that a function can take. For example, given the following type: ```ts type Factorize = { (input: number): number[] (input: bigint): bigint[] } ``` Behvaiour before: ```ts expectTypeOf<Factorize>().parameters.toEqualTypeOf<[bigint]>() ``` Behaviour now: ```ts expectTypeOf<Factorize>().parameters.toEqualTypeOf<[number] | [bigint]>() ``` There were similar changes for `.returns`, `.parameter(...)`, and `.toBeCallableWith`.

this is mostly to reduce the unrelated diff on #83 - it's essentially the same refactor of moving the type-utils like
Not<...>,Extends<...>,Eq<...>et al. to a utils.ts file. I would like for that to be strictly overloads-related as much as possible esp. since it's a potentially controversial change.FYI @aryaemami59 not sure if this will make it harder for you to merge main into your other PR, or if you plan on continuing to do that.
