Class TemplateSplitter

java.lang.Object

de.ruedigermoeller.template.TemplateSplitter

public class TemplateSplitter
extends Object

 This transfomrs a given ("template"-)file into another file, applying the following rules:
 - normal content is transformed to a java-program
   e.g. the input:
   'hello this is some text'
   will result in
   'out.println( "hello this is some text" );'
 - content escaped using '<%' and '%>' is not transformed to 'out.println( .. )' code.
   e.g. the input:
   'hello <%for int i = 1; i < 10; i++) {%> this is some text <% } %>'
   results in:
   'out.print( "hello" );
   for int i = 0; i != 10; i++) {
     out.print( "this is some text" );
   }'
 - content escaped using '<%+' and '%>' is transformed to 'out.println( "xxx" + content )' code.
   e.g.
   'hello <%for int i = 1; i < 10; i++) {%> this is <%+i%> some text <% } %>'
   results in:
   'out.print( "hello" );
   for int i = 0; i != 10; i++) {
     out.print( "this is "+i+"some text" );
   }'


 known problems
  - 2 escapings without any content produce incorrect output ("<%xy%><%yz%>")
    workaround: "<%xy%><%yz%>" is aequivalent to "<%xyyz%>"
  - since unescaped input is transformed into 'out.println( "unescaped text" )'
    quotes have to be java-style escaped in the input file.  e.g.
    'these are \"quotes\"'  ==transformed to==>  'out.println( "these are \"quotes\"" )'
    same applies to '\'
    'this is one backslash: \\'  ==transformed to==>  'out.println( "this is one backslash: \\" )'
