Unexpected ParserError about noline HOT 4 OPEN

I had a similar problem so I went digging:

EditorBuilder::build_sync will send these bytes and expect a response indicating the terminal size

Your Console provides an invalid response which results in the error.

Btw, you should use self.0.pop() instead of self.0.last() in your Read impl.

@Tim-Paik Sorry for not responding, I missed the github notification so I didn't see this before now.

Do you have a full example I can have a look at?

You can execute the following command to reproduce my problem

cargo new nolinetest
cd nolinetest
cargo add noline --features alloc

Populate src/main.rs with the code from main.rs that I provided at the beginning, after that, you can use cargo run to run it

Looks like you're making sense, since I'm not providing a terminal width, which noline definitely needs. But I don't know how should I provide the size of the terminal...

from noline.

Noline expects to be connected to an ANSI terminal. During init, noline probes the terminal using ANSI escape codes to get the size of the terminal. You can have a lock at here for an example of a mockterminal.

But, what is your use case here? Without an actual terminal, noline isn't of much use.
