* Add tests showing existing behavior for indexing types with never.
* Make T[never] = never instead of erroring or being any.
And update the baselines for the tests for this change.
* Add test case for indexing an expression with never showing existing behavior.
* Make indexing an object with never expression result in never.
And update baseline to reflect new behavior.
* Add compiler option to enable declaration sourcemaps
* Transparent goto definition for sourcemapped declaration files
* Post-rebase touchups
* Rename API methods
* Fix lints
* Fix typo in name XD
* Log sourcemap decode errors
* Share the cache more, but also invalidate it more
* Remove todo
* Enable mapping on go to implementation as well
* Allow fourslash to test declaration maps mroe easily
* more test
* Handle sourceRoot
* Add tests documenting current behavior with other sourcemapping flags
* Ignore inline options for declaration file maps, simplify dispatch in emitter
* Change program diagnostic
* Fix nit
* Use charCodeAt
* Rename internal methods + veriables
* Avoid filter
* span -> position
* Use character codes
* Dont parse our sourcemap names until we need to start using them
* zero-index parsed positions
* Handle sourceMappingURL comments, including base64 encoded ones
* Unittest b64 decoder, make mroe robust to handle unicode properly
* Fix lint
* declarationMaps -> declarationMap
* Even more feedback
* USE Mroe lenient combined regexp
* only match base64 characters
* Fix nit
* Add test case and temporarily disable inference
(Inference of class members from this-assignments inside a
prototype-assigned function.)
* Update baselines
* In blocks and source files, bind functions first
* Add tests from other bugs
* Remove temporary failsafe
* Update tests to restore intent and clean up errors
* Restore intent even better
* Restore intent even better x2
* Add missed baselines
* Undo 'any' inference propagation
Removing this only changes one test slightly, and fixes JQuery types,
which rely on the old method of inference.
* Add jquery regression test and update baselines
* Restore any inference propagation to wildcard only
* Retain comments on (and produce sourcemaps on) the equals token in initializers
* Improved comments/sourcemaps for await, yield, while, and for
* Retain comments on block curly-braces
* Emit comments for if statements
* Improved switch case comment emit
* Improve comment and sourcemap emit for try/catch, throw, and continue statements
* Improve sourcemap emit and comments for with statements
* More accurate sourcemaps+comments emit for new, typeof, void, and delete
* Improve comment emit for element access expressions
* Preserve more comments on imports and exports
* Make function a bit more defensive like other usages of emitTrailingCommentsOfPosition
* Support preserving comments within empty lists
* Handle leading comments of tokens, conditionally indent leading comments
* Stop heuristically sourcemapping tokens
When the transform was trivial it worked, but was unneeded, but when it was complex, it was brittle - best leave source mapping up to the transformers
* Fix unneeded +1
* Tighten up element access comments
* Handle comments on parenthesized expression tokens
* Fix nit
* Have getNameOfSymbolAsWritten quote nonidentifier nonnumeric symbols all the time
* Revert checker changes
* Reuse synthetic origin to indicate that derived declaration name may need to be quoted
* Use a limited version of getApparentType that doesnt map primitives
* Reuse [most of] getBaseConstraintOfType, since it does the needed behaviors
* Move new function next to the very similar function
* Changed "Duplicate Identifier" to "enum can only be merged..."
when either declaration of the identifier is an enum.
Partial (?) fix for #529
Not sure if the new test is necessary, all the cases seem to have been covered by others tests.
* picked a nit
* Use getAllowSyntheticDefaultImports to access `--allowSyntheticDefaultImport` value
* Fix#21788: Handel missing imporotClause case
* Fix#21789: Add a defensive check to forgottenThisPropertyAccess code fix for non-identifier locations
* Do not suggest prefix with `this` if the name we are looking for is diffrent from the errorLocation
* Fix#21796: Handel case of unknown module
* Add check to capture more info for #21800
* Fix#21807: check for symbol before looking up its flags
* Fix#21812: Gracefully fail if the token is not `this`.
* fix: `matchedText` was not properly extract the correct parts from the candidate
closes: #21636
* core: replace `substr` with `substring` in `matchedText`
* test: remove redundant code from tests
* Fix JSX contextual types to not eagerly become apparent
* Apply changes from code review, unify common code
* Fix jsx children contextual typing
* Light code review feedback
* Use fillMissingTypeArguments
* Accept nonliteral jsx child type
* Add test for the fillMissingTypeArguments case
* Only apply global augmentations before globals are available
* Add detailed comment explaining the split of global/nonglobal augmentations
* Remove trailing whitespace
* Overloads in Array.concat now handle ReadonlyArray
Previously it was union types, which is slower.
* Make arrayConcat3 test stricter
* Switch to InputArray instead of adding overloads
* Update baselines
* Update baselines correctly
* Rename to ConcatArray and add slice method
Should make it, respectively, easier to understand this specific type
and harder to satisfy it by mistake.
