* WIP
* Test no longer crashes, but emit trampoline is incomplete and skips pipeline phases
* Fix lints, use non-generator trampoline in emit (still skips pipeline)
* Final version with emitBinaryExprssion work stack that is only used if possible
* Fix lints
* retarget to es2015 for testing
* Use bespoke state machine trampolines in binder and checker
* Remove now extraneous code in parser
* Adjust fixupParentReferences to use a depth first preorder traversal rather than breadth first
* Reintroduce incremental fast bail in fixupParentReferences
* Revert target to es5
* PR feedback
* Small edit for devops rebuild with updated definition
* Fix comment nits, add internally extraneous check back into transformer
* ESNext+[[Define]]: reference to param props illegal
When target: "esnext" and useDefineForClassFields: true, property
declaration initialisers should not be able to reference parameter
properties; class fields are initialised before the constructor runs,
but parameter properties are not:
```ts
class C {
foo = this.bar
constructor(public bar: string) { }
}
```
emits code that looks like this:
```js
class C {
bar
foo = this.bar
constructor(bar) {
this.bar = bar
}
}
new C('x').foo.length // crashes; foo is undefined
```
This PR adds an error on foo's declaration with ESNext+[[Define]].
* improve test
* Emit statements before super
When statements come before super, Typescript's emit is incorrect,
whether there is an error or not. This change preserves statements that
come before super whether there is an error or not.
Here is the case with no errors:
```ts
class Test extends Array {
p: number
constructor() {
console.log("p is initialised in the constructor below super()")
super()
this.p = 1
}
}
```
Notice that `p` is manually initialised in the constructor after
`super()` instead of at the property declaration.
* Update baselines
Parameter properties in the error case now move below the super call.
This is an improvement because it means the code is more likely to execute
correctly.
* remove outdated comments
* Change type-only semantics to allow type queries
* Don’t error using type-only import in ambient context
* Fix default import
* Fix namespace import
* Update more baselines
* Prevent circular resolution
* Track const enum expression usage
* Update baselines
* Perf tuning 1
* Test commit for perf impact
* Weave type-only alias declaration finding into alias resolution
* Fix namespace import of type-only exported symbols
* type-only exports do not contribute to the module object type
* Update APIs
* Fix enum casing, remove type-only conversion suggestion
* Short circuit type-only checks in resolveEntityName faster
* Fix casing in API
* Remove unused parameter
* Fix error on qualified names in type queries
* Allow type-only imports in computed property names
* Fix computed property names of types and abstract members
* Remove unused util
* Commit missing baselines
* Rename “check” functions so as not to overload the word “check”
* Adds support for showing default exports in the navtree - Fixes#34601
* Handle the feedback in #35477
* Navigation items using default export or export = will get noted if they are a const vs function
* fix meta property from appearing twice
* handle case where ImportMeta has props defined
* rename file
* use exclude instead of exact
* undo comment
* this file should have no change
* change file name back
* add more test cases
* remove comment and text validation
* fix formatting
Previously these were incorrectly treated just like normal properties:
```ts
class Parent {
a: any;
constructor(arg: any) {
this.a = arg;
}
}
class Child extends Parent {
declare a: number;
constructor(arg: number) {
super(arg);
console.log(this.a); // Property 'a' is used before being assigned. (2565)
}
}
```
Fixes#35327
* Check combined intersection properties against target index signatures
* Add tests
* Accept new baselines
* Less aggressive check for index signatures
* Track intersection membership state for both source and target
* Minor fixes
* Get jsdoc host from chained assignment
getSourceOfAssignment previously only checked one level of binary
expression instead of following binary expressions all the way to the
right. This meant that binding of `@constructor` would fail in the
following example:
```js
/** @constructor */
a = b = function () { }
```
* cleanup lint
* use existing utility
* Correctly resolve tags for function overloads. Fixes#30181
* Better fix for #30181. Added more unit tests
* Fix commentsOverloads tests
* Fallback to first signature when doc and tags are empty
* Fix crash in codefixes re: braces of class body
Previously, the code that finds braces of a class body assumed they were
always there. This is not always the case, so this code checks for
that.
* fix semicolon lint
