single file build

[madair]

add a build target to create a 'compiled' app that would do the following:

• analyse the application definition and create a single file build that includes only the widgets referenced by the application definition
• pre-process the application definition into a json object and include it in the single file build
• include config.json in the single file build

The result would be a template that loads a single javascript file that includes everything required to get started.

Implement the YUI compressor in build.xml

(In [1385]) re #53:

• builds all of fusion in a single file
• will parse an AppDef file for required Widget and Map js files and include only those files in the SF build.xml
• converts AppDef to a JSON structure and includes it
• add YUI compression

Hey, that's pretty darn cool.

Will there be an option for sites that are running multiple fusion apps off the same install to specify multiple appdefs?

[madair]

in response to Jason, no not as it stands since the AppDef gets converted to JSON and included in the single file. Multiple fusion apps would each be "compiled" into separate JavaScript files in included in the app's script src tag.

However all other Fusion files (CSS/PHP/images) would come from a shared install of Fusion.

[madair]

including the AppDef JSON structure should be optional, i.e. if not specified in the ant build process, it's not included and Fusion behaves as before loading AppDef and converting to JSON at run time.

[jbirch]

Mike, is including the appdef currently optional, or is this a future enhancement (should be?)? I'd love to see MapGuide 2.0.1 use a single-file build.

How does this impact extensions? If using a single-file build, will extensions not in the build still be loaded at runtime?

[madair]

extensions are supported in the singleFile build as long as they are installed in fusion/ext. Including the AppDef is not optional at the moment, this will be fixed for 1.0.5.

(In [1390]) closes #53: makes pre-parsing and including ApplicationDefinition optional.
