* Type `this` in more constructor functions
Previously, `this: this` in constructor functions only when there was
an explicit `@constructor` tag on the function. Now, `this: this` for
any function that's known to be a constructor function.
This improves completions inside constructor functions; also note that
previously the compiler *did* type `this: this` inside methods of constructor
functions, so this fix makes us more consistent. This is reflected in
the large number of baselines that improve.
The fix is a simple switch to `isJSConstructor`, which is the standard
way to detect constructor functions. I'm not sure why the original PR
didn't use this method.
I remember discussing this limitation in the original bug, #25979, and
I guess I decided that it made sense. But I was heavily primed by the bug's
framing of the problem in terms of `noImplicitThis`, which *should*
require an explicit `@constructor` tag.
With better typing comes better detection of `@readonly` assignment; I
had to fix the readonly detection code to use `isJSConstructor` as well.
* Remove `Add @class tag` fix for noImplicitThis.
The new rules mean that it never applies. It's possible that it should
apply to functions like
```js
function f() {
this.init()
}
```
In which `init` is never defined, but I think this program is incomplete
enough that not offering the fix is fine.
* Fix precedence of `@this`
Previously, both `@class` and `@this` in a jsdoc would cause the `@this`
annotation to be ignored. This became a worse problem with this PR,
because `this` is correctly typed even without the annotation.
This commit makes sure that `@this` is checked first and used if
present.
* Add codefix for --noImplicitThis
* Code review
* Back to building post-merge
* Remove redundant functions + update tests
Infer-from-usage also inserts `this: any` parameters when needed, so I
removed that from fixImplicitThis.
Otherwise, fixImplicitThis has better suggestions than inferFromUsage,
so I moved inferFromUsage later in the suggestion order.
* More redundancy removal
Don't need to add `@this` anymore either since inferFromUsage will do
that.
* More baseline updates
From moving inferFromUsage down in priority I think?
* remove now-redundant ad-hoc jsdoc emit
* fix more bad merge
