How to break the Crystal program use REPL when running `crystal spec`?

We can always add a debugger, and run it use crystal i, it works.

But, my concerns is, how to do same thing when run crystal with crystal spec?

Just run the specs with crystal i. The spec command doesn’t really do anything substantially different. It’s mostly convenience features like implicitly requiring an entire directory tree. You can’t have that with crystal i, but you probably don’t need it when you want to run a specific spec in the debugger.

Eventually I’d like to add an i spec or speci command for that.

It works! i really should be think of it.

$: crystal i spec/
