Fixes #378
Fixes #387
This PR is for adding support for multiple file processing, with support for exporting and importing declarations even between files.
It makes use of a
TransformManagerwhich transforms various files and uses aProgramMapto memoize and keep track of dependencies across files, which helps in reducing expensive transform calls to declarations already referenced from other files.Rather than transforming every declaration in a source file, the type checker gets the declarations exported from the file, and processes those declarations and its dependencies only, making processing faster
The type checker helps to resolve types and imports, as well as resolve import declarations. Import declarations are not parsed by default so that we know we are only making use of imports actually referenced in code (which is helpful in single outputs for instance).
(The program map makes use of
package:pathsPathMapto easily work with paths for files and declarations, as the TS output may resolve either to a relative import in the file, or may reference the declaration externally as an absolute path).Imported declarations are declared as
ReferredTypes with aurlproperty, which allows for referencing the normalExports are rewritten based on how they are specified, and are processed after transformation (since they are separate declarations and may be referenced as they are.
Imports are processed depending on the presence of the file:
