* Handle intersection types when looking up base types for visibility
* Extract protected constructor check to function and recur on intersections
* Remove unneeded cast
* Introduce truncation into node builder and symbol display part writer
* Change default maxa truncation length to 240
* Fancy truncation + higher hard limit
* get return type from `@type` tags
Previously, getJSDocReturnType did not check the `@type` tag for a type
node that has a return type. Now it does.
* Improve doc comment of getJSDocReturnType
* More type predicates in type guards!
* Update API baselines with new documentation (?!)
* Index signatures contribute properties to unions
This means that in a union like this:
```ts
type T = { foo: number } | { [s: string]: string }
```
`foo` is now a property of `T` with type `number | string`. Previously
it was not.
Two points of interest:
1. A readonly index signature makes the resulting union property readonly.
2. A numeric index signature only contributes number-named properties.
Fixes#21141
* Correctly handle numeric and symbol property names
1. Symbol-named properties don't contribute to unions.
2. Number-named properties should use the numeric index signature type,
if present, and fall back to the string index signature type, not the
other way round.
* Rework symbol visibility checking to allow for multiple potential containers
* Express a preference for the local symbol if accessible from the enclosing declaration
* navigateTo: Collect results from all referenced projects.
* Don't use project references, just source maps
* Move more code to session
* Test when implementation file is deleted
* Use tsserver tests instead of fourslash tests to ensure session is used
* Support find-all-references
* Restore fourslash tests
* Update emit baselines (added missing newline)
* Support rename
* @weswigham code review
* Don't open/close files
* Avoid growing `toDo` too eagerly
* @sheetalkamat code review
* Also get symlinked projects for originalLocation
* Update API (#24966)
* More @sheetalkamat code review
* Remove unnecessary test
* Update API (#24966)
* Optimize sourcemap application more
* Remove test-only memory hog sourceMapDecodedMappings field
* Update for style, remove unused function that triggers warnings in node 10
* Avoid all raw buffer constructor calls
* Small TDZ fix
Previously, redirected source files merged the same way as other source
files, effectively causing the target of the redirection to be merged
twice. mergeSymbol now has an assert (`source===target`) that catches
this condition, so this change makes sure to skip redirected source
files.
This change doesn't apply to the preceding binding loop, since the
binder handles already-bound source files correctly.
Previously variable declaration+function expression worked.
Note that class expression/class declaration do not work, due to the way
they are specified. I added a test for future reference.
