Re: [Caml-list] [announce] O'Browser : OCaml on browsers
Hi ! Thank you for this amazing work ! I'm rewriting large parts of my website using this tool, and I may have found two little bugs : * get_attribute (in rtjs.js) when get_attribute toto returns a boolean, value_from_string returns the empty string (this is nasty ..) (temporary) solution : in rtjs.js, just cast on line 33 with something like return value_from_string (v == null ? : (v+)); * input (in js.ml) it seems that the editable function editable = ( function true - (try Node.remove_attribute node disabled with _ - ()) | false - Node.set_attribute node disabled disabled ); works better. (at least it works with buttons, check boxes and so on) Thank you again ! All best, William Le Ferrand www.beouifi.org 2008/11/21 Benjamin Canou [EMAIL PROTECTED] Hi, From Kuba Ober: Pardon the question, but is this meant to be useful in the future, or is it just a fun experiment (in which case the next target should be brainfuck). Coming soon: the OCaml VM on a turing machine ! From Burgisser Francois : Good idea but maybe a browser plugin to manipulate DOM would be much more efficient. From Gabriel Kerneis: But, sadly, much less portable. From Jon Harrop: Could you write a compiler and call eval to get better performance? From David Thomas: I'd like to see a plugin that makes available to JS a function to execute ocaml bytecode. Our plan is to achieve efficiency with a (not yet available) browser plug-in (the original bytecode interpreter or the native compiler) while remaining portable by using the JavaScript VM where the plug-in is not available. So we don't currently focus on optimizing (and complexifying) too much the JavaScript version. From David Teller: To me, the fact that you can write portable lightweight applets sounds like a good enough reason. That and the fact that I can see this being used by stuff like Ocsigen to make for (even) richer client-server applications. Indeed, as Vincent wrote, even if O'Browser is at this point only a client-side scripting core, it takes place into the Ocsigen project and will be used to interact with (OCaml) server code (in its current form or not).

Re: [Caml-list] [announce] O'Browser : OCaml on browsers
I'd like to see a plugin that makes available to JS a function to execute ocaml bytecode. There could be a standard way to check for support, and the pure javascript interpreter could be loaded if it is missing (for those browsers/computers on which performance is reasonable). --- On Tue, 11/18/08, Vincent Balat [EMAIL PROTECTED] wrote: From: Vincent Balat [EMAIL PROTECTED] Subject: Re: [Caml-list] [announce] O'Browser : OCaml on browsers To: caml-list@yquem.inria.fr Cc: [EMAIL PROTECTED] Date: Tuesday, November 18, 2008, 10:32 AM Hi, On Tuesday 18 November 2008 19:15:28 Kuba Ober wrote: On Tuesday 18 November 2008, you wrote: On Mon, 2008-11-17 at 22:43 -0500, Kuba Ober wrote: Please note that this is an early version, in particular the DOM interface module is neither pretty nor well typed.
