Re: [htmltmpl-java] tmpl_include

Sometime Today, Thomas Wabner assembled some asciibets to say:

well, it can't be implemented because tmpl_include is processed much 
before the variables are handled.  basically, when the template is being 
read, all tmpl_includes are read in and inserted at the relevant 
positions.  It's only after all this has happened that tmpl_vars are 
processed.

furthermore, adding this feature will break compatibility with the 
HTML::Template perl module.

It can be done with a Filter, when that's done.  I'm still working on 
it.

you can do this with the path and search_path_on_include parameters to 
the constructor.  Since this is done programmatically, you can have the 
path read from a configuration file.  This is the way I do it.

All include templates will be in a static location.  Just include that 
path in the path variable, and specify only the template filename in the 
tmpl_include, and not the full path.

eg:

global_templates/
   include_1.tmpl
   include_2.tmpl

local_files/
   main1.tmpl
   main2.tmpl


main1.tmpl:

<tmpl_include file="include_1.tmpl">


main1.java:
	set path to /path/to/local_files, /path/to/global_templates
	set search_path_on_include to true
	initialise template
