When you're too lazy to change your code, so you change the compiler instead.

Instructions

1. Clone this somewhere
2. Install gulp if you don't have it already (npm install -g gulp)
3. Compile the compiler with gulp local
4. Point VSCode to this build of tsc by adding "typescript.tsdk": "<cloned directory>/built/local" to your VSCode user settings (or workspace settings)
5. Make sure you have a tsconfig.json for your source directory
6. Restart VSCode or relaunch the TSServer by running CMD+Shift+P => TypeScript: Restart TS Server

Additional functionality

• Added support for .es6 file extensions as JS
• Import paths that begin with leading slashes are interpreted as from the project root, not the disk root
• Fixed type parser on JSDoc object literal types that spanned multiple lines
• Added support for templated classes via JSDoc. Previously, @template could only be used for functions; they are now valid class declaration tags and will be an available type within the entire class scope
• @typedef tags with no identifier names are now legal, if the JSDoc comment is attached to a variable declaration with no assigned expression or initializer (identifier is inferred from the variable name)
• @return statements on constructors no longer throws an error if the return type is the containing class type
• Mark JSDoc types that have type (...|undefined) as optional parameters
• Add support for the @interface tag on classes
• Interpret identifier statements as type definitions if they have a @typedef tag attached
• Added support for the @enum tag

Todo

• (Bug) Fix the symbol binding on enum declarations
• Support for namespaced enum declarations, e.g. SomeClass.EnumName should emit SomeClass as a namespace declaration.
• Variadic function parameters should be marked optional
• Add support for the @inheritdoc and @private tags
• Add a warning if an optional parameter is not supplied
• Change the error message to be "Constructor return type does not match containing class type" if a return tag on a constructor does not match
• Check for the diagnostic errors I removed in program.ts and add them back again with more constrained checks against NodeFlags.Hacked
• Actually clean up my fixes and put them in functions so I can rebase against upstream and not die from all the conflicts
• Rewrite all of my code as proper parse subtrees instead of rewriting nodes
