bin	6a29f342de Changed -g to -d for additionally creating deployment files in jtalkc. Added -S for using libraries files using a common suffix. Fixed jtalkc so that it works on MacOS X (mktemp syntax). Moved all node/webos examples into a new examples directory.	13 vuotta sitten

Jtalk

By Nicolas Petton petton.nicolas@gmail.com

Jtalk is an implementation of the Smalltalk language that runs on top of the JavaScript runtime. It is designed to make client-side development faster and easier.

Overview

Jtalk is written in itself, including the parser and compiler. Jtalk compiles into efficient JavaScript, mapping one-to-one with the equivalent JavaScript. There is no interpretation at runtime.

Some highlights:

Jtalk features an IDE with a Class browser, Workspace, Transcript, a ReferencesBrowser supporting senders/implementors and class references, basic Inspector and even a beginning of a Debugger and a unit TestRunner.
Pharo Smalltalk is considered as the reference implementation.
Jtalk includes a canvas to generate HTML, like Seaside
Jtalk can use Javascript libraries and the current IDE is built on jQuery
You can inline Javascript code and there are many ways to interact between Jtalk and Javascript

How to commit changes from the web-based IDE

The Jtalk class browser is able to commit changes to disk. The "commit category" button will send a PUT request with the JS code of all classes in the selected class category in a file named js/CATEGORY.js and also send the corresponding .st files to the st directory.

The easiest way to enable committing is probably to setup a webdav with Apache.

The following steps explain how to setup a webdav for Jtalk with Debian, but the setup on OSX and other Linux distros should be similar.

Install Apache and enable the dav module

apt-get install apache2
a2enmod dav
a2enmod dav_fs

Create a password for the webdav

htpasswd -c /etc/apache2/htpasswd-webdav USERNAME

Setup the webdav for Jtalk

Add the following lines to the default vhost (in /etc/apache2/sites-available/default):

Alias /jtalk/ "/path/to/jtalk/"
    <Directory "/path/to/jtalk/">
        Options Indexes MultiViews FollowSymLinks
    DirectoryIndex index.html
    AllowOverride None
        Order allow,deny
    allow from all

    Dav on

    AuthType Basic
        AuthName "jtalk"
        AuthUserFile /etc/apache2/htpasswd-webdav
    <LimitExcept GET OPTIONS>
            Require valid-user
    </LimitExcept>

    </Directory>

Make sure the group www-data has required rights to modify files in the webdav directory.

Restart Apache

/etc/init.d/apache2 restart
