This package provides the capability to represent common Smalltalk objects as Javascript syntax to be sent to a web browser for execution / interpretation. It also provides DynamicCompiler parsers for Javascript and CSS. This package is a cut of the code in Scriptaculous for generating Javascript from Smalltalk objects.
Each object implements #asJavascriptOn: aStream which transforms the objects representation in to the javascript version, for example:
"Dictionary in to Javascript Hash"
| stream |
stream := String new writeStream.
Dictionary new
at: #boolean put: true;
at: #nil put: nil;
at: #string put: 'y';
at: #number put: 5;
at: #code put: 'this.value' js;
asJavascriptOn: stream.
stream contents
"OrderedCollection in to Javascript Array"
| stream |
stream := String new writeStream.
OrderedCollection new
add: 'y';
add: 5;
add: 'this.value' js;
asJavascriptOn: stream.

stream := String new writeStream.
