"rustlings" command output is unreadable when run in Windows 7 cmd

[TobiasWehrum]

Hello,

I've just installed rustlings according to the Windows instructions. When I execute rustlings, here is what I see:

I've also tried running it in bash and powershell with the same result.

[TobiasWehrum]

Alright, so what I believe to be ANSI escape sequences show up correctly in ANSICON. That's not perfect (I'd much rather use the CMD), but at least I can use it now.

[TobiasWehrum]

A few steps further down the line: Running ansicon -i apparently patches my system so that cmd.exe also supports the ANSI escape sequences now. I'm happy with that result.

For other people running Windows 7 it might help to either investigate how to display it properly without installing/running anything (this StackOverflow answer suggests it's possible with C) or to add a note to the readme that they might want to download and run ansicon with the -i flag if the rustlings output looks all jumbled up.

i would classify this as a bug if it doesn't run correctly on an unmodified windows version

[komaeda]

if anyone who runs windows could help me debug this, that'd be appreciated!

[TobiasWehrum]

Ready! What do you need?

[TobiasWehrum]

Oh, unless you need that person to actually know anything about Rust as opposed to e.g. execute and try things for you. I'm a complete newbie.

@TobiasWehrum i've been wanting to remove the weird formatting anyways because it would eliminate a dependency and right now it just looks nice and nothing else. i'll ping you when i have a working build of that so you can try it out for me!

Windows 10 x64 => also having the same issue with the output

I will give you any information to assist with the fix just let me know what you need.

I get the same issue with rustlings 1.2.2 on Windows 10 (version 1803 for x64). Tried in both cmd and PowerShell, with the same result.

Edit: For anyone coming here with the same issue, a workaround for doing the rustlings exercises without strange output is to just use Windows Subsystem for Linux. Just make sure to install rust there as well (the regular Windows installation doesn't work). Also make sure you have gcc installed.

This should be fixed by #167!
