Text Oriented Universal Programming Language

Toupl is a super programming language, designed for text generation tasks. Syntax based on Foobar 2000 Tagz Script, but modified and extended for more power, symmetric, easy and generic. Currently supporting generation to:

C++ C# Java JavaScipt ECMAScript Lua PHP Python Visual Basic.

Syntax

Because language designed for text generation, text may be simply outputted as is.

Hello world!Target language variable or expression can be outputted by enclosing in % % tags

Variable var0 is equivalent var0
1+2=%1+2%Target language code can be included by enclosing in ?% %? tags

?%
int i;
int n=100;

while(iNative condition output supported

?%
var _genImage=function(src,alt,width,height) {
%?

?%
return fpText;
}
?Conditional text putted between [ ] tags and will be outputted if all condition variables inside not null. Conditional variables same as ordinary variables but enclosing by & %& instead % %.

There is a comments

/%
block comment
/
// line comment In situation, when you need output text, that contains elements\tags of toupl,you can enclose this in special ignore tags !% %!

!% all /% this % text ?% outputted ] %!
! even !% you can output !
! if you want to output %!%! - simply twice is %!

Technical details Depends from target language text outputted as append operation to String fpText or to StringBuilder fpStringBuilder (Java and Visual Basic cases). In case of C++ language you can specify work String class (default - std::string). In native condition construction variables tested with bool _fpT(String) function. You must code it.
