This intorduces a new symbol-based declaration emitter - currently this
is only used for JSON and JavaScript, as the output is likely worse than
what the other declaration emitter is capable of. In addition, it is
still incomplete - it does not yet support serializaing namespaces.
* Add tests for various import/export forms, add notes on export as namespace and fix export * from
* Tests & fixes for computed names
* Add test with current @enum tag behavior
* fix declaration emit for jsdoc @enum tags
* Small adjustments to base class serialization to fix bugs in it
* Guard against type/type parameter confusion when using typeParameterToName a bit
* Integrate feedback from PR
* Fix issue with export= declarations visibility calculation and type declaration emit that impacted all forms of declaration emit
* Only make one merged getCommonJsExportEquals symbol for a symbol
* Support preserving type reference directives in js declarations
* Skip declare mdoifiers for namespace members in ambient contexts
* FAKE ALIASES AND NAMESPACES EVERYWHERE
* Dont do namespace sugar when type members contain keyword names
* Fix json source file export modifier under new output
* Such clean nested aliasing, very wow
* Fix lint
* Add visibility errors, reuse type nodes where possible
* Suppoer having correctly named import types in bundled js declaration emit & adjust binding to allow namespaces with aliases to merge when the aliases look to be type-only
* Better support for module.exports = class expression
* Fix discovered crash bug
* Allow export assigned class expressions to be reachable symbols from external declarations
* Add missing semicolon
* Support @enum tag post-merge
* preserve comments on signatures and declarations where possible
* Basic support for js classy functions
* Add example we should do better with
* Prototype assignments make things a bit wonky, but the example from the PR seems OK
* Make a ton of changes to support the new way js classes are bound
* Remove some old comments, fix import and export default names
* Fix bug in object define handling and add tests for object define property declaration emit
* Fix organization nits from PR comments
* Preserve comments from jsdoc declarations on properties and js declaration type aliases

* Stylistic refactors in the symbol serializer
* Another round of PR feedback, mostly style, small bugfix with constructors, and test showing bug in export assigned class expression name shadowing
* Use x instead of index
* Add test that fails because file is written multiple times
Reported from #33061
* Handle seenEmittedFiles which was not being set when emit of a file was complete.
It was issue only when errors are reported before emitting (which puts the files into pendingEmit that needs to check only in seenEmittedFiles)
If emit happens before semantic diagnostics query this issue is not repro, because the affected files come into play and those are being set correctly
Fixes#31398
* make baselining source map optional
* Handle emitDeclarationOnly in --build scenario
* Ensure we are using d.ts emit as signature even when --declarationMap is on (map files are emitted before d.ts)
* Move module specifiers to verifyTsBuildOutput
* implement create Hash to be default hashing plus data so we can verify it easily in baseline
* Remove failing baseline
* Accept correct baseline name
* Resolve module specifier relative to moduleFile.originalFileName
* Use baseline testing for outputs
* Added skipLibCheck to test
* Switch to using vfs.formatPatch for output
* Add basic test for current behavior
* Fixes getting destructured variables references(#31922)
* Add test case that renames destructured property
* Fixes missing nested object destrucuturing variable references
This will test that iteration is in insertion order, new entries added during iteration will be visited by the iterator, and values can be deleted while an iterator is running.
