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 and transcript
- Pharo Smalltalk is considered as the reference implementation
- Jtalk includes a canvas to generate HTML, like Seaside
- Jtalk includes a jQuery binding
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
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
