JLang

Just a simple template language ANTLR4 grammar.

Some compatible code examples

mixing plain text with code:

2+2/2 = <?2+2/2?>.

loop for:

<% for (int i=0; i<10; i++) { %>
<? i ?>
<% } %>`

loop while:

<%
var i = 0; 
while (i < 10) { 
%>
<? i ?>
<%
    i++; 
} 
%>

if-elseif-elseif-else:

<% 
if (a<10) { 
%>

a < 10

<% 
} else if (a < 20) {
%>

a < 20

<% 
} else if (a < 30) {
%>

a < 30

<% 
} else {
%>

a is big

<%    
}
%>
