StringTemplateParser

StringTemplateParser is parser for string templates, where macros are defined with JSP-alike markers. During parsing, macros are replaced by their values. Values are resolved by custom MacroResolver.

Usage is quite simple:

    // prepare template
    String template = "Hello ${foo}. Today is ${dayName}.";
    ...
    
    // prepare data
    Map<String, String> map = new HashMap<String, String>();
    map.put("foo", "Jodd");
    map.put("dayName", "Sunday");
    ...
    
    // parse
    StringTemplateParser stp = new StringTemplateParser();
    String result = stp.parse(template, new MacroResolver() {
        public String resolve(String macroName) {
            return map.get(macroName);
        }
    });
    // result == "Hello Jodd. Today is Sunday."

StringTemplateParser is very configurable. User can set the escape character, or starting and ending strings (by default: ${ and }). There is an option if missing keys should be resolved, and the replacement value for missing keys. Good practice is to create and configure one StringTemplateparser instance that will be used in your code.

StringTemplateParser by default detects inner macros in passed string. However, you can turn on parsing values as well.
