I wish I could narrow down the problem more precisely than this, but since updating to 1.6.0, I have begun to encounter very strange behavior when calling `using Polyhedra` (and various other packages) from the REPL embedded in Atom with Juno. Julia itself starts just fine, but as soon as I try to import a package, the screen blanks out and I get all these strange blank lines:

 ![image](https://global.discourse-cdn.com/julialang/original/3X/f/c/fce9f23a1b4a0b37233224536b60aec6ea7cd2ad.png)

It just hangs like this. I don’t think it is a compatibility issue with a specific package, because this happens for most of the external packages that I have installed (although built-in packages like Random work just fine).

I am using Atom 1.55.0, Juno 0.12.6, and Windows 10 Home build 19042.928.

Any ideas?

To start, please read [PSA: make it easier to help you](https://discourse.julialang.org/t/psa-make-it-easier-to-help-you/14757), particularly point 1.

It’s not clear how you generated a bunch of blank lines, and an image of blank lines can’t really help us to provide you with additional advice.

Point 1 in the PSA asks to provide a code sample.

Unfortunately, there really isn’t much more to this than what’s in the OP. The steps to replicate this behavior on my machine are

1. Install Julia 1.6.0 and a third-party package, such as `Polyhedra`.
2. Open a new Julia 1.6.0 project in Atom.
3. Run Julia, then type `using Polyhedra` (this is my full code sample) into the REPL in Atom.

This results in the output shown in the screenshot.

Clearly, not everyone is having this issue, so I assume the problem is with my environment. But that consists of thousands of things: my Windows build, my localization settings, my hardware. I have no idea which of these is causing the issue, so I am posting here on the hope that someone has experienced the same phenomenon and was able to trace it to a specific element of their Julia stack.

Atom probably evaluates into Julia [this initialization script](https://github.com/JunoLab/atom-julia-client/blob/a61023683d0a926d3496d1396c667c064e27bdd4/script/boot_repl.jl). I made some [modifications](https://gist.githubusercontent.com/goretkin/f34e48e873dc4d63c856778bbfbe6601/raw/0214bdbbca80b8a914b2264ce20ce02396ec98e1/atom-boot-repl.jl) so that it can run stand-alone

```julia

That the terminal interface is seemingly failing may be related to the underlying issue, but perhaps you can try to run the steps above in a non-Atom terminal to see what you get.

Sounds like you figured out how to fix one of the errors I made! Sorry about that. I’ve edited the post.

You should download the file pointed to by the link, save it to e.g. the path `"C:\\Users\\Max\\atom-boot-repl.jl"`. You can do this however you’d like. Here’s one way within Julia:

```julia
julia> using Downloads

Aha, I get it now.

Oddly, the process you have described works just fine in an isolated terminal, although I get somewhat different output:

Is that “would connect” line significant?

That’s just something I put in because I commented out the part where it actually tries to connect to Atom.

Can you use [GitHub - julia-vscode/julia-vscode: Julia extension for Visual Studio Code](https://github.com/julia-vscode/julia-vscode) instead of Juno / Atom? I’d recommend that.

I mean, for certain values of _can,_ I can. But I really like the Atom interface, and since it works fine on my other machines, I’d prefer not to switch to an unfamiliar tool.

Is there a reason, beyond this apparently rare bug, to use VS Code instead of Atom in general? When I started with Julia, I read that Atom was the definitive development studio of choice.

Take a look at [GitHub - JunoLab/atom-julia-client: Juno a good IDE?](https://github.com/JunoLab/atom-julia-client)

> **Attention** : We have decided to join forces with the [Julia extension for VSCode](https://github.com/julia-vscode/julia-vscode). As such, this Atom-based plugin is effectively in “maintenance-only mode” and we expect to only work on bug fixes in the future.

There is a thread or two about it, but short the Atom ~lost~ to VS Code generally.
