Can't enable Raw Mode on MacOS/iTerms terminals

[AmirShelli]

I'm trying to build a text editor using Mordant, but everytime I try to enter raw mode the app stops showing anything except for the cursor when used in iTerm.

Code:

package basics

import com.github.ajalt.mordant.input.*
import com.github.ajalt.mordant.terminal.Terminal

fun main(){
    val terminal = Terminal()
    terminal.cursor.move{
        clearScreen()
    }
    terminal.enterRawMode().use { rawMode ->
        while (true) {
            val event = rawMode.readKey()
            if (event.isCtrlC) break
            terminal.print("You pressed: ${event.isCtrlC}")
        }
    }
}

I ran the application, types "hey". this is what the application displays

Until I press Ctrl-C, it just quits the app without printing anything in.

Am I doing something wrong? is there some way to enable raw mode on Mac?

P.s: appreciate the library, I've been looking for something like this for a while :)

Are you on the latest 2.7.2? That release should have fixed raw mode on macos.

Oh! Sorry, yes it fixed it! I was on 2.7.1 😆
