In Mac OS, when typing with readln etc. I can't use the cursor keys. Works in Windows though.

That's normal, line editing on Unix terminals is a kinda advanced library feature. The most common lib to do it, GNU readline, is actually a big thing that pushed the GPL because of how useful it was and it happened to use that license.

I wrote one too though it is a bit bulky.
https://github.com/adamdruppe/arsd/blob/master/terminal.d

import terminal;
void main() {
   auto terminal = Terminal(ConsoleOutputMode.linear);
   auto line = terminal.getline("your prompt: ");
   terminal.writeln("You wrote: ", line);
}

compile:

dmd yourapp.d terminal.d

I get these errors with terminal.d (on OSX):

Joels-MacBook-Pro:small joelcnz$ rdmd term.d
arsd/terminal.d(1268): Error: undefined identifier 'SIGWINCH'
arsd/terminal.d(1381): Error: undefined identifier 'SIGWINCH'
Joels-MacBook-Pro:small joelcnz$

Note: I've got term.d as the main file, I've got terminal.d in arsd folder

I've put up an issue on your github site.

There's a missing value in the signal header for OSX !

Could you run this little C program for me on your Mac and let me know the output?

---
#include<stdio.h>
#include<signal.h>

int main() {
	printf("%d\n", SIGWINCH);
}
---


I can't find the numeric value online either and I don't have a mac myself to check the headers :( ugh.

     28    SIGWINCH     discard signal       Window size change

Or just take it from the man page:

ah excellent. My web search came up with https://developer.apple.com/library/ios/documentation/System/Conceptual/ManPages_iPhoneOS/man2/sigaction.2.html which didn't give the value!


anyway the git is updated now

That's because it's iOS. You have to be careful with apple documentation, they look the same for both MacOS and ios, but often they are slightly different.

Now I get the error:
object.Exception@terminal.d(2745): too narrow terminal to draw

It has a negative number in it.

Thanks for working on it.
