ttypescript | TypeScript tool to use custom transformers | JSON Processing library

I'm using ttypescript to hook my custom transform into the compiler, which works just fine. I've identified a situation in which I need to throw a compile error (syntax error) along the same channels and in the same format that typescript does.

How do I do this?

I have a project with mocha tests that rely on ts-nameof.

The mocha tests is supported by Mocha sidebar in VSCode.

When trying to refresh my tests (in the tests sidebar) I have a ReferenceError: nameof is not defined.

My understanding is that I have to setup Mocha sidebar to somehow use ttypescript instead of typescript (like I did with VSCode).

I know this VSCode plugin rely on ts-node since they are asking to set the VS settings "mocha.requires": [ "ts-node/register" ].

I tried to look for a "tts-node" package (a ts-node like but for ttypescript), or what exactly is this "ts-node/register" and help me finding better keywords to search for, but didn't find an answer.

I tried to add "ttypescript" and "ts-nameof" in the mocha.requires, this didn't change anything.

I did find that ts-node can accept a --compiler setting that could (maybe?) be ttypescript, however, I don't know how to provide it to the Mocha sidebar plugin.

I am trying to inject a module
import statement by transformer.ts

(* I used ttypescript and it works,
But some statements are uninterpreted.)

and I succeeded in inserting the import statement
but the import statement that I injected
was not translated intermittently into the es5 grammar.

This is the code that I used in transfomer.
