Catalyst Configure Schema

1, App class will load config option into self.
2, Other class query App class about its config option. For example, Model::DB will try to query its option in $config->{Model}->{DB}.
3, Catalyst default uses Config::General to load config from {app_name}.conf
4, Class can setup configure item in its source file by __PACKAGE__->config( {info} ), and this config function will return the current package level configure options.

Local config

By default, Catalyst try to local appname.conf, but it also try to load a local config file: appname_local.conf, which contains high priority value than appname.conf.
The __PACKAGE__->config() has lowest priority.

So use __PACKAGE__->config() to setup default configuration.
Use appname.conf to setup configure wish included into version manager system.
Use appname_local.conf to complete items in release mode.

User can use envoriment variable CONFIG_LOCAL_SUFFIX to change 'local' to other value.

Config::General config format

<name1> will map to a named field: $parent->{name1} = { value inside block }.
<name1 name2> will map to $parent->{name1}->{name2}
name = value will match to name=>value
name = value1
name = value2 will match to name => [ value1, value2 ]

Find a google project for building perl in android: perldroid which has a wiki page.
I follow the instruction of it and try it on ubuntu 8.10 machine. But unfortunatly, I am failed. I checked the compile error, I guess the reason is that bonic (Android's verion libc) lack the define of div_t. I will try to build it later.

Android use YAFFS2 as its root filesystem.
For extract it, you can use a tool named "unyaffs", which can be found in http://code.google.com/p/unyaffs/.
This tool will extract content of image file into current directory. You'd better to create a new directory to hold them.
For making YAFFS2 image, please use binary tool mkyaffs2image. The tool is built in ./out/host/linux-x86/bin/mkyaffs2image

Android wiki

var tag;
var func = function(){
return afunc( tag );
}

is not a correct usage.

The correct one is:

var genFunc = function( ptag ){
var ltag = ptag;
return function(){afunc( ltag )};
};

genFunc( tag );

1, Add message to Assert statement to make code easy.
2, Use subscribe() listen custom event of TestRunner.
3, Use YAHOO.log() to output log.
4, var Assert = YAHOO.util.Assert to use YAHOO's assert.
