@Keno Any solutions about this issue. |
|
I've seen this too. I think it's an ITerm issue. Let me investigate. |

The REPL beeping (blinking) code made the assumption that the prompt prefix is always a String. That's not necessarily the case, and in fact it can be an arbitrary funcion to be called when the prompt is printed (e.g. TerminalExtensions uses this for the iTerm integration). However, even worse, this code acquired a lock that it never released on error, causing a deadlock. Fix the original assumption and also add a try/catch/finally block such that future errors print the error rather than deadlocking the terminal. Fixes Keno/TerminalExtensions.jl#40

Thank you very much!

Turned out to be a Julia issue. See linked PR. |

Excellent. This is a “lifesaver “.

I have had some problems with TerminalExtensions freezing my julia session so that I can't type anything and things like Ctrl-C have no effect. It seems to occur in a variety of situations. I am using TerminalExtensions 0.4.0, iTerm2 3.2.3 and have reproduced it with julia 0.7.0 and 1.0.1. Here is a simple example that reproduces it on my machine from the start of a fresh julia session:
using TerminalExtensionsand hit returnaaI have also run into similar freezes when using tab completion, but haven't been able to come up with a reproducible example of this. Maybe the issues are related?
