Support tsx files with exported typescript parser

[evans]

Adding the jsx plugin provides the ability to parse typescript files containing jsx syntax. See facebook/jscodeshift#180 (comment) for more color.

Thanks for this, @evans! Those test failures seem relevant, though. I had thought that JSX conflicted with some TypeScript <type> syntax, or I would have enabled it by default.

I think it is better to provide a new exported "tsx" parser rather than modifying existing "typescript" parser so that users can use it as they want.

This seems unlikely to move forward, so I’m closing it. Consumers of recast can easily add the jsx plugin if they like.

It's a little bit sad to see that this was closed.

TSX has some syntax conflicts with generic type parameters (e.g. const fn = <T>(t: T) => t), but it is worked around in TypeScript by specifying extension (.tsx vs .ts).

Maybe we could reopen the PR, and just define it as a new parser.

I know that I can define plugins manually, but it was really close here.

For the parser name IMO it should be typescriptReact (at least it the official name):

Sorry, after trying, indeed there are collisions between syntaxes as the current PR defines plugins.
