feat(ivy): a generic visitor which allows prefixing nodes for ngtsc (#24230) This adds ngtsc/util/src/visitor, a utility for visiting TS ASTs that can add synthetic nodes immediately prior to certain types of nodes (e.g. class declarations). It's useful to lift definitions that need to be referenced repeatedly in generated code outside of the class that defines them.

feat(ivy): able to compile @angular/core with ngtsc (#24677) @angular/core is unique in that it defines the Angular decorators (@Component, @Directive, etc). Ordinarily ngtsc looks for imports from @angular/core in order to identify these decorators. Clearly within core itself, this strategy doesn't work. Instead, a special constant ITS_JUST_ANGULAR is declared within a known file in @angular/core. If ngtsc sees this constant it knows core is being compiled and can ignore the imports when evaluating decorators. Additionally, when compiling decorators ngtsc will often write an import to @angular/core for needed symbols. However @angular/core cannot import itself. This change creates a module within core to export all the symbols needed to compile it and adds intelligence within ngtsc to write relative imports to that module, instead of absolute imports to @angular/core.

refactor(ivy): implement a virtual file-system layer in ngtsc + ngcc (#30921) To improve cross platform support, all file access (and path manipulation) is now done through a well known interface (`FileSystem`). For testing a number of `MockFileSystem` implementations are provided. These provide an in-memory file-system which emulates operating systems like OS/X, Unix and Windows. The current file system is always available via the static method, `FileSystem.getFileSystem()`. This is also used by a number of static methods on `AbsoluteFsPath` and `PathSegment`, to avoid having to pass `FileSystem` objects around all the time. The result of this is that one must be careful to ensure that the file-system has been initialized before using any of these static methods. To prevent this happening accidentally the current file system always starts out as an instance of `InvalidFileSystem`, which will throw an error if any of its methods are called. You can set the current file-system by calling `FileSystem.setFileSystem()`. During testing you can call the helper function `initMockFileSystem(os)` which takes a string name of the OS to emulate, and will also monkey-patch aspects of the TypeScript library to ensure that TS is also using the current file-system. Finally there is the `NgtscCompilerHost` to be used for any TypeScript compilation, which uses a given file-system. All tests that interact with the file-system should be tested against each of the mock file-systems. A series of helpers have been provided to support such tests: * `runInEachFileSystem()` - wrap your tests in this helper to run all the wrapped tests in each of the mock file-systems. * `addTestFilesToFileSystem()` - use this to add files and their contents to the mock file system for testing. * `loadTestFilesFromDisk()` - use this to load a mirror image of files on disk into the in-memory mock file-system. * `loadFakeCore()` - use this to load a fake version of `@angular/core` into the mock file-system. All ngcc and ngtsc source and tests now use this virtual file-system setup. PR Close #30921 2019-06-06 20:22:32 +01:00			`"//packages/compiler-cli/src/ngtsc/file_system",`
