* Don't recommend to install '@types/foo' if that already exists
* Add different extra diagnostic text if the @types package exists
* Update API (#24966)
* getDeclarationIdentifier handles undefined name
getNameOfDeclaration actually doesn't handle all declarations, only
those that produce names that could be reasonably used as an identifier.
Until now, getDeclarationIdentifier assumed that getNameOfDeclaration
always returned a name. This caused crashes whenever we tried to get the
name of something like a Constructor.
* Add test and baselines
* getNameOfDeclaration can return undefined
This requires all callers to handle it, which turns out now to be too
disruptive.
* Fix lint
* Check extends tag first in getClassExtendsHeritageClauseElement
Previously getBaseTypeNodeOfClass checked, but this is only used in a
few places.
* Fix names and add test
* Update API baseline
* Move jsdocAugments tests to conformance/jsdoc
* Better naming in checkClassLikeDeclaration
Previously, getJSDocCommentAndTags could recur up to four times if any
of four predicates matched. However, to avoid duplicates, the predicates
have been tuned to be mutually exclusive, which means that the recursion
can be turned into a while loop. The while loop is much simpler and
safer, since it is guaranteed to only walk up the tree one time. In
addition, the extra check that adds jsdoc from initializers only runs
once, before the loop, further reducing the opportunity for duplicate
jsdocs.
I thought about further simplifying the code that gets the next node to
check, but to know when to stop the loop, I'd need a predicate that is
as complicated as the code in `getNextJSDocCommentLocation`, so I kept
the existing code, just reordering it for compactness.
* Generate normal 1-part sourcemaps (at increased processing cost), since tools dislike sectional ones
* Add semicolon
* Accept sad baselines]
* Forward along sourcesContent if available
* Supress lint since the API actually calls for null here
* Fix concatenated sourcemap paths
* Accept bad baselines :(
* Add overloads
* Accept api update
* Fix lint
* avoid circularity in getTypeOfVariableOrParameterOrProperty
Modify getTypeOfVariableOrParameterOrProperty to get the type of the
variable declaration before widening it. This essentially avoids some
circularities by (1) setting the type of the variable declaration to the
unwidened type (2) updating the type of the variable declaration to the
widened one.
You will still get a circular noImplicitAny in (1), for expressions that
actually are circular, but not in (2), for the containers of things that
are not themselves circular.
* Stop checking js init object literals via checkObjectLiteral
* checkBinaryExpression: new code for special assignments
* Chained lookup for js initializer type
* Check for JS-specific types only once
Also make sure to respect the type annotation if there is one.
* Accept API changes
