* No did-you-mean-to-call error on casts
I chose to do the ad-hoc check rather than yet another tree walk.
1. It's faster to run and easier to read.
2. This error came from looking at real code. It happened twice, so I
think the best estimate for other uses that happened zero times is in
fact zero.
3. I couldn't think of other places to put the cast, given the
restrictions on `testedNode` just before the new code.
* Skip parentheses

e350c357 (#40228) introduced a subtle bug: it switched the flags to an
alias, dropping `SymbolFlags.Property` --- and that makes
`symbolIsValue()` get to the `resolveAlias(symbol)` call, which leads to
`getPropertyOfType()` with`resolved.callSignatures`+`constructSignatures`
being `undefined`. So initialize them in `setStructuredTypeMembers`
before calling `getNamedMembers()`.
Fixes#42350
The original error message on the last line I have added to in
functionParameterArityMismatch.ts was
No overload expects 5 arguments, but overloads do exist that expect
either 4 or Infinity arguments.
even if we do not define a function that takes Infinity arguments.
This PR changes it to this:
Expected 0-6 arguments, but got 5 or more.
I feel it is still a bit strange but much more understandable.
Fixes#42418
* Signature help: support non-trailing rest parameters
In signature help, the first rest parameter will always be the *last*
'current' parameter (disregarding types). Previously, the signature help
current-parameter highlight was only correct for trailing rest
parameters. However, with tuple types, you can now create non-trailing
rest parameters. This PR now correctly highlights non-trailing rest
parameters as the last 'current' parameter.
For example, `names` should be the current parameter in all the calls
below:
```ts
declare function loading(...args: [...names: string[], allCaps: boolean, extra: boolean]): void;
leading(/**/
leading('one', /**/
leading('one', 'two', /**/
```
And, because signature help doesn't do real overload resolution, `names`
is also the current parameter for other calls:
```ts
leading(1, 2, 3, 'ill-typed', /**/
leading('fine', true, /**/
```
* Change 'variadic' to 'rest'
* fix missed rename
* use single, original tuple instead
* Revert "use single, original tuple instead"
This reverts commit f0896f32ea3d523f1186e9bea2446f75f3a182de.
* Improve sig help of trailing rest too
1. Trailing rest keeps highlight at end instead of going off the end.
2. Non-trailing rest disable highlight entirely (by putting the index
one past the end).
* update API baselines
* Make object literal properties new identifier locations when not contextually typed
* Fix completions after comma in object literal
* Update other test
* @typedef: Improve error spans from declaration emit
This is a proof-of-concept fix. I think it could be expanded for all of
jsdoc, but I only set it up for jsdoc type aliases. It could use a lot
of polish too.
* track error node in isSymbolAccessible instead
* Switch to using enclosingDeclaration
Remove trueErrorNode
* add test of @callback and @enum
* Better error + fix @enum error
Since enums don't have a name property, you *have* to call
`getNameOfDeclaration` to go looking through the AST for one.
* Support Top Level "for await of".
* Add test cases for top level "for await of".
* Apply suggestions from code review
* add test cases
* remove redundant variables
* fix test baselines
* Update diagnostic message and tests
