Program interface changes

• TypeChecker.emitFiles is no longer available; use Program.emit instead.
• Getting diagnostics are now all centralized on Program,
  • for Syntactic diagnostics for a single file use: Program.getSyntacticDiagnostics(sourceFile)
  • for Syntactic diagnostics for all files use: Program.getSyntacticDiagnostics()
  • for Semantic diagnostics for a single file use: Program.getSemanticDiagnostics(sourceFile)
  • for Semantic diagnostics for all files use: Program.getSemanticDiagnostics()
  • for compiler options and global diagnostics use: Program.getGlobalDiagnostics()

Tip: use ts.getPreEmitDiagnostics(program) to get syntactic, semantic, and global diagnostics for all files

All usages of 'filename' and 'Filename' changed to 'fileName' and 'FileName'

Here are the details:

• CompilerHost.getDefaultLibFilename => CompilerHost.getDefaultLibFileName
• SourceFile .filename => SourceFile.fileName
• FileReference.filename => FileReference.fileName
• LanguageServiceHost.getDefaultLibFilename => LanguageServiceHost.getDefaultLibFileName
• LanguageServiceShimHost.getDefaultLibFilename => LanguageServiceShimHost.getDefaultLibFileName

The full list of APIs can be found in this commit

The syntacticClassifierAbsent parameter for the Classifier.getClassificationsForLine is now required

See Pull Request #2051 for more details.

Changes to TextChange

TextChange.start and TextChange.length became properties instead of methods.

SourceFile.getLineAndCharacterFromPosition

SourceFile.getLineAndCharacterFromPosition became SourceFile.getLineAndCharacterOfPosition

APIs made internal as they are not intended for use outside of the compiler

We did some cleanup to the public interfaces, here is the full list of changes:

• Commit 2ee134c6b3c0ec
• Commit 35dde28d44122c
• Commit c9ef4db99ac93bb1c166a

• Commit b4e5d5b0b460cc88a10db

typescript_internal.d.ts and typescriptServices_internal.d.ts have been removed

The two files exposed helpers in the past that were not part of the supported TypeScript API. If you were using any of these APIs please file an issue to re-expose them; requests for exposing helper APIs will be triaged on a case-per-case basis.

For more information please see the full change.
