@georgewfraser Thanks!
Could you split this into 2 PRs? The first to add the rustc-driver-example.rs and the second to add the link. That way the CI link check passes.

I'd like to create another directory and put |

@JohnTitor if you tell me what you want that directory to be named, I will set up 2 PRs, one with the example, one with the link. |

ctx should be named tcx here to match the compiler convention.

Outdated

Not sure listing the types is very helpful.

If you know nothing about the compiler internals (like me!) it's quite helpful for understanding what each of these options actually does.

OK @mark-i-m this is just the .rs file now, once this is merged I will make a new PR with the changes to the .md file. |
It's pretty hard to figure out how to use rustc_interface. This adds a simple "hello world" example of using rustc_interface to parse and typecheck a single file.
