[Ironruby-core] ir / iirb on Mono

The command history on Windows when running ir.exe is being provided by the Windows console subsystem; it's not actually part of IronRuby. I imagine that Mono's readline library could be used to give the same effect on non-Windows platforms.

Hi All,

I've noticed problems with iirb and ir interactive mode on my Mac. I'm running the 1.0-rc2 build.

With ir, I've noticed two things:

1) The up arrow does not scroll through the command history. This works on Windows.

2) the first character doesn't appear, though is processed, for each line. For example, if I open a new ir session and type 'puts "Hello, World"' the console shows:

 >>> uts "Hello, World"

but if I hit return, the command is processed just fine. It's literally just the first character - I often end up hitting space then backspace or something else before typing and then it is fine.


With iirb, I'm getting an exception just trying to run it:

cory-foys-macbook-pro:~ foyc$ iirb
IronRuby.Libraries:0:in `GetExecutable': infocmp -C (Errno::ENOENT)
	from IronRuby.Libraries:0:in `CreateProcess'
	from IronRuby.Libraries:0:in `CreateProcess'
	from :0:in ``'
	[Stack Trace truncated]

Running infocmp -C produces:

I'm happy to look into both of these, but wanted to see if anyone else was seeing this before I did (or was looking at it already).
