* Checker:Remove block-scoped duplicate declaration errors in plain JS
Previously they were issued in mergeSymbol, not they are not issued.
* fix semicolon lint
1. During name resolution, `@param` and `@return` tags should walk up
through the jsdoc comment and then jump to the host function. Previously they
did not, which would cause them to not resolve type parameters bound in
the scope of a host that was not a sibling of the comment. The example
from #46618 is a prototype method:
```js
/**
* @template {T}
* @param {T} t
*/
C.prototype.m = function (t) {
}
```
2. During name resolution, prototype methods are supposed to resolve
types both from the host function's location and from the containing
class' location. The containing class lookup happens in a separate call
to `resolveName`. Previously, the code that finds the containing class
only worked for the above style of comment, which is on the outer
ExpressionStatement, but not for the below style, which is on the
function expression itself:
```js
C.prototype.m =
/**
* @template {T}
* @param {T} t
*/
function (t) {
}
```
* Fix duplicate completions from two different copies of a node_modules package
* Fix logic for scoped packages
* Fix errors from merge
* Less gross way to reconcile these two conflicting PRs
* Allow structure reuse if a declaration file within a package is updated
Closes#47471
* Use correct program to obtain source file in structure reuse test
This removes a few places where global compiler bindings are mutated:
1. Make `sysLog` call an internal binding which is changed via
`setSysLog`.
2. Use `Object.assign` to change values *in* `objectAllocator` instead
of mutating the binding itself. (The type should verify that any
future uses of this will properly override all bindings.)
3. `localizedDiagnosticMessages` is not really needed as an exported
value, there's only one place that uses it to test whether it is set
or not. So drop the export and replace it with a new
`maybeSetLocalizedDiagnosticMessages` (internal) function.
* Allowed non-this, non-super code before super call in derived classes
Fixes#8277.
It feels wrong to put a new `forEachChild` loop in the checker, though in the vast majority of user files this will be a very quick one. Is there a better way to check for a reference to `super` or `this`?
* Used new isNewThisScope utility and dummy prop in baselines
* Accounted for parameters and get/set accessor bodies
* Accounted for class extensions
* (node|statement)RefersToSuperOrThis wasn't checking root level scope boundaries
```ts
function () {
return this;
}
```
It was immediately going to `ts.forEachChild` so the statement itself wasn't being counted as a new `this` scope.
* Better 'references' name and comments; accounted for more method edge case
* Limited super calls to root-level statements in constructor bodies
As per discussion in the issue, it would be ideal to consider any block that always ends up calling to super() the equivalent of a root-level super() statement. This would be valid:
```ts
foo = 1;
constructor() {
condition() ? super(1) : super(0);
this.foo;
}
```
...as it would compile to the equivalent of:
```ts
function () {
condition() ? super(1) : super(0);
this.foo = 1;
this.foo;
}
That change would a bit more intense and I'm very timid, so leaving it out of this PR. In the meantime the requirement is that the super() statement must itself be root-level.
* Fixed error number following 'master' merge
* Added decorator test cases
* Again allowed arrow functions
* Accepted new baselines
* Added allowance for (super())
* Reworked emitter transforms for ES this binding semantics
In trying to adjust to rbuckton's PR feedback, this orders derived class constructor bodies into five sections:
1. Pre-`super()` code
2. The `super()` call itself
3. Class properties with initializers
4. Parameter properties
5. The rest of the constructor
I've looked through the updated baselines and it looks like they're generally better than before. Within the existing test cases that result in semantic errors for `this` access before `super`, several previously resulted in a global `_this` being created; now, they correctly defer referring to `_this` until it's assigned to `_super.call(this) || this`.
* Used skipOuterExpressions when diving for super()s; fix prop ordering
* Allow direct var _this = super() when no pre-super() statements; lint fixes
* Always with the TSLint
* One last touchup: skipOuterExpressions in es2015 transformer
* Fixed new lint complaint in utilities.ts
* Again added a falls-through; it'd be swell if I could run linting locally
* This time I think I got it

* Undid irrelevant whitespace changes
* Mostly addressed private/field issues
* Accepted derivedClassSuperProperties baseline

* Next feedback: superStatementIndex
* Feedback: simplified to no longer create slice arrays
* Adjusted for default and rest parameters
* Added test case for commas
* Corrected comment ranges
* Handled comments after super, with tests

in `getContainerFlags`, move cases for get/set accessors
to fallthrough into the block that currently handles MethodDeclaration;
so get/set accessors and method declarations all get the same container flags,
such that during `bindContainer`, `startFlow.node` is assigned to
getters/accessors
(this changes a public api in tsserverlibrary.d.ts and typescript.d.ts
by adding `GetAccessorDeclaration` and `SetAccessorDeclaration` to the type
of `FlowStart.node`)
consolidate predicates checking whether a node is either a get or set
accessor, into `isObjectLiteralOrClassExpressionMethodOrAccessor`
(formerly `isObjectLiteralOrClassExpressionMethod`)
annotate updated test with `@target: es2020`
* fix `isObjectLiteralOrClassExpressionMethodOrAccessor`
require that Getter/Setters are parented by an ObjectLiteralExpression or ClassExpression
1. `getRawLiteral()`: barf if `currentSourceFile` is missing, since if
it is, then the following `getSourceTextOfNodeFromSourceFile` will
return a bogus `""`.
2. One `||` -> `??` change.
3. `backtickQuoteEscapedCharsRegExp`: escape the usual control
characters except for a simple LF. This code does get used to
generate backtick strings when `rawText` is not given, and not
escaping things like TAB characters can get mangled by editor
settings. Worse, not escaping a CRLF and putting it verbatim in sthe
string source will interpret it as LF, so add a special case for
escaping these as `\r\n`.
Added test.
