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
* Simple first version
Doesn't cover or test any complicated variations.
* Lots of cases work
Destructuring does not. But
- skipping node_modules and lib.* does.
- call expressions does
- property access, including with private identifiers, does
* Support variable declarations, property assignments, destructuring
As long as it's not nested
* More cleanup
* skip all d.ts, not just node_modules/lib
* Offer a codefix for a lot more cases
* remove incorrect tuple check
* Use getSymbolId instead of converting to string

Plus add a check that errorNode is an argument to the call, not the
call's expression.

whether or not somebody tried to assign undefined to them in the
erroneous assignment

* Always issue cannot find name did-you-mean error
This PR issues "cannot find ${name}, did you mean ${name}" errors for
identifiers and propery access expressions in JS files *without*
`// @ts-check` and without `// @ts-nocheck`. This brings some benefits of
Typescript's binder to all Javascript users, even those who haven't
opted into Typescript checking.
```js
export var inModule = 1
inmodule.toFixed() // errors on exports
function f() {
var locals = 2
locale.toFixed() // errors on locals
}
var object = {
spaaace: 3
}
object.spaaaace // error on read
object.spaace = 2 // error on write
object.fresh = 12 // OK, no spelling correction to offer
```
To disable the errors, add `// @ts-nocheck` to the file. To get the
normal checkJs experience, add `// @ts-check`.
== Why This Works ==
In a word: precision. This change has low recall — it misses lots
of correct errors that would be nice to show — but it has high
precision: almost all the errors it shows are correct. And they come
with a suggested correction.
Here are the ingredients:
1. For unchecked JS files, the compiler suppresses all errors except
two did-you-mean name resolution errors.
2. Did-you-mean spelling correction is already tuned for high
precision/low recall, and doesn't show many bogus errors even in JS.
3. For identifiers, the error is suppressed for suggestions from global files.
These are often DOM feature detection, for example.
4. For property accesses, the error is suppressed for suggestions from
other files, for the same reason.
5. For property accesses, the error is suppressed for `this` property
accesses because the compiler doesn't understand JS constructor
functions well enough.
In particular, it doesn't understand any inheritance patterns.
== Work Remaining ==
1. Code cleanup.
2. Fix a couple of failures in existing tests.
3. Suppress errors on property access suggestions from large objects.
4. Combine (3) and (4) above to suppress errors on suggestions from other, global files.
5. A little more testing on random files to make sure that precision
is good there too.
6. Have people from the regular Code editor meeting test the code and
suggest ideas.
* all (most?) tests pass
* NOW they all pass
* add tonnes of semi-colons
* restore this.x check+add a test case
* make ts-ignore/no-check codefix work in unchecked js
* Issues errors only in the language service
* add a few more tests
* fix incorrect parentheses
* More cleanup in program.ts
* Improve readability of isExcludedJSError
* make diff in program.ts smaller via closure
* Switch unchecked JS did-you-mean to suggestion
Instead of selectively letting errors through.
* undo more missed changes
* disallow ignoring suggestions
* Issue different messages for plain JS than others
Straw text for the messages, I just changed the modals to avoid name
collisions.
* Fix discovery of more pnpm symlinks
* Add some tests
* Never show pnpm paths in auto imports, even if there’s no other path
* Import statement completions can return none
* Fix tests
* Add failing test showing poor symlink cache reuse
* Fix test, fails for right reasons now
* Preserve cache built up during program creation, then fill in with program resolutions
* Remove obsolete comment
* Remove obsolete type assertion
* Revert fully filtering out ignored paths
* Add test case for 'useUnknownInCatchVariables'.
* Add new 'useUnknownInCatchVariables' flag.
* Accepted baselines.
* Add test for catch variable explicitly typed as 'any'.
* Accepted baselines.
* Move option under 'strict'.
* Accepted baselines.
* 'useUnknownInCatchVariables' is strict in command line help.
* Add unqualified JSDoc member references
This allows unqualified references like:
```ts
class Zero {
/** @param buddy Must be {@link D_HORSE} or {@link D_DOG}. */
deploy(buddy: number) { }
static D_HORSE = 1
static D_DOG = 2
}
```
I surveyed @see and @link again to estimate how common this is. I found
a little over 200 uses, which is around 2%. Sorted by frequency, this
*is* the next feature on the list, along with the `module:` prefix.
So I think this is about the right point to stop adding code.
In this case, however, I liked most of the uses -- there were a lot
of deprecated functions that referenced a function just below, where it
would be wordy to qualify the name, but the reader would benefit from a
link.
Note that unqualified references do *not* work inside type or object
literals. The code I ended up with is quite complicated and I didn't
observe any uses in the wild.
Fixes#43595
* Remove type/object literal container check
Since they don't work anyway
* Ensure static index signatures have an errorNode available
* Lookup static index signature declarations in the right symbol table, stop checking prototype props
* Add @linkcode and @linkplain tags
They are just like @link tags but request fixed-width and normal
presentation, respectively.
Fixes#43935
* revert JSDocComment -> JSDoc SyntaxKind rename
* update API baselines
* fix lint
* support QualifiedName when narrowing inside loops
* add test
* narrow more qualified names
* handle `undefined` of `getFlowCacheKey `
* update comments in test
* Everything mostly works
A couple of mixed, nested references don't work yet.
The scanner+parser interaction is wrong, the parser consumes one too
many spaces, and the checker+services code needs a little cleanup.
* Cleanup
1. I decided that correctly parsing a#b.c, an entity name containing an
instance reference, is not worth the work.
2. I made the scanner, at least the jsdoc part, emit a # token, and
provided a reScanPrivateIdentifier in order to convert #a to # a.
3. I cleaned up the code in the checker.
2. Unrelated: I added a missing space in linkPart display.
* Cleanup lint + var naming
* investigate+clean up a couple of TODOs
* Fix lint in utilities.ts
* change name to JSDocMemberName
* address PR comments
