The new stacktrace printing in Julia 1.6 is great, but sometimes the amount of information printed can become a bit overwhelming and difficult to navigate so I’ve packaged up some code I’ve had locally for a little while into:

> **[GitHub - MichaelHatherly/InteractiveErrors.jl: Interactive error messages for...](https://github.com/MichaelHatherly/InteractiveErrors.jl)**
>
> Interactive error messages for the Julia REPL. Contribute to MichaelHatherly/InteractiveErrors.jl development by creating an account on GitHub.

which others might find useful too 🙂 I’ll let the demo and the README explain the rest:

Requires Julia `1.6+` and isn’t registered at the moment.

This looks really cool! One thing I think might be useful would be to integrate this with [Cthulhu.jl](https://github.com/JuliaDebug/Cthulhu.jl), which already has functionality similar to this and would allow exploring the optimized and unoptimized IR of function in the backtrace as well.

Thanks. Yes I’ve been considering integrating Cthulhu into it somehow, just haven’t come up with a nice approach to doing it yet.

This is really neat!

(Do you plan to register the package?)

Thanks, yeah probably will, seems like there’s sufficient interest.

Latest release adds some simple integration for running `ascend` and `descend` from Cthulhu as well as `JET.report_call` on selected method calls from stacktraces.

`0.1.4` will be available shortly. It includes optional syntax highlighting for source (courtesy of `OhMyREPL`), as well as display of method signatures (highlighted, and formatted using `JuliaFormatter`) for ease of reading. Here’s a nice little example of everything turned on
