Is it possible to create native-OSX GUIs from OCaml code?

Not quite but there have been attempts. Googling for Cocoa in the  
archives may help.

I'll pose a question of my own...

Is anyone using a MacBook (13") to hack OCaml all day? How do you  
like it?

	Thanks, Joel

I use SDL built from macports, with ocamlsdl built from godi (on my 13"
MacBook, which works quite well for me).  SDL isn't exactly a GUI toolkit
though, so you'd have to write your own widgets on top of it, or try to wrap
an existing set of sdl widgets written in C.

It's OCaml mode usually works fine, but there are a few places it  
messes up: the "with" record syntax is the most notable.  Mainly, I  
like (a) the drawer with the file tree, (b) tabbed editing, (c) code  
folding, (d) Cmd-whatever and menus instead of Ctrl-X Ctrl-S, Meta- 
this, Alt-that, etc.  I was always a VIM guy instead of emacs, so I  
never got the hang of emacs control sequences.  Downsides are that  
(a) not programmable, and (b) you have to keep a terminal open to  
build, etc.

You have to admit, when you buy a Mac, you're (at least partly)  
paying for aesthetics.  TextMate takes advantage of those.  Now if I  
could just find a terminal that did the same...

Yeah... unfortunately, the regex matching that the syntax hilighting is 
based on hakes it hard to get certain constructs right.  I believe this is 
supposed to be overhauled in v2.0 (which is dependant on Tiger).  BTW: 
what's wrong with the with record syntax?  It seems to work fine for me.

Well, it is scriptable, so you could write a script that tould take care 
of that for you.  Ocamlbuild should help make this a bit less painless as 
well.

Actually, my biggest annoyance is that you can't easily do something like 
jump to the ith character of a selection (though I could prabably write a 
script for that too), which is needed for working with large exressions in 
the toplevel where it identifies errors by location and not highlighting.

Copy this into TextMate:

type t = {
x : int;
y : float
}

let _ =
   let r = { x = 1; y = 1.0 } in
   let r' = { r with x = 2 } in
   (* ... Syntax highlighting has stopped working here ... *)

That's where it fails because of the "with".  It's the only obvious  
bug I've run across, but if you have something like that early in the  
code, the rest of your code is not highlighted.  Maybe I have an old  
version of the bundle if you don't see this problem.

It highlights fine for me.  Try grabbing the latest version of the bundle.

Re: [Caml-list] OSX GUI

[Jonathan Bryant]

(I guess this is getting a bit off topic for this list, but I'll  
press on anyway)

I just did with GetBundle and I'm still having the same problem.  Is  
there any way to tell what version of the bundle I have so that I can  
see if it is the latest version?  I can't seem to find that.

I'm not sure, but I recommend getting it from subversion.  I had problems
with it when I used getbundle, so I went back to checking out the bundles
with subversion.  You might also want to install cmigrep (it's in godi) in
order to use the ocaml experimental completions bundle.

Well, I'm assuming that getBundle is using subversion to manage the 
bundles (I just use svn).  In which case, something like:

svn info ~/Library/Application\Support/TextMate/Bundles/OCaml.tmbundle

will tell you your current version (assuming that's the path to your 
bundle -- change as necessary).

The current revision is 7453, and the OCaml bundle was last changed in 
revision 7410.

It works fine here, you must have an old version of the bundle.  You 
should do an svn up to grab the latest changes.

Unison is an OCaml program with a native OSX GUI (as well as a GTK one).
However, it is basically an Objective C interface with an OCaml  
binding. Nevertheless, it might help you.

See: http://www.seas.upenn.edu/~bcpierce/unison/download/releases/
Look for the "uimac" and "uimacnew" subdirs inside the distribution.

Re: OSX GUI

[Jeff Shaw]

For now the easiest way to make a GUI on macos x in caml is labltk. The 
other option is Lablgtk, but you have to run lablgtk applications in the X11 
server until GTK is ported to use mac-native widgets.

As for coding caml on macs, it's great. I use aquamacs emacs with the tuareg 
mode installed. I'd rather code on a desktop but if you want a small laptop, 
a mac is great.

Installing ocaml on macos:

install macports
open terminal
sudo port install ocaml +labltk

(ifyou need lablgtk2)
sudo port install lablgtk2

Macport's version of tk doesn't give native widgets (whereas the built-in 
distribution does), so then I do

sudo port -f uninstall tk
sudo port -f uninstall tcl

And if you don't like the mac keyboard's placement of the alt key, the 
keyboard control panel lets you swap the alt and apple keys.
