> StrSubstitutor replaces variables in values. And currently there's no way to
> turn this off.
> Why turn it off: I want to replace some variables in a simple template. Some
> of the replacement values are arbitrary user input.
> At the moment I escape all dollar signs in the replacement values with "$$".
> This is annoying. Especially as I use one template with variables as a value
> for another variable. Here I have to escape twice.
> Here's some example code. At the moment it prints:
> {code}
> Hello Hamburg from Hamburg
> {code}
> The commented line is my suggestion for this feature. If it works, it should
> print:
> {code}
> Hello ${city} from Hamburg
> {code}
> {code}
> // untrusted user input
> String userInputName = "${city}";
> String userInputCity = "Hamburg";
> Map<String, String> valueMap = new HashMap<>();
> valueMap.put("name", userInputName);
> valueMap.put("city", userInputCity);
> String source = "Hello ${name} from ${city}";
> StrSubstitutor strSubstitutor = new StrSubstitutor(valueMap);
> // strSubstitutor.setEnableSubstitutionInValues(false);
> System.out.println(strSubstitutor.replace(source));
> {code}
