> In StrSubstitutor variable replacement works in a recursive way. 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 replacemnt values are arbitrary user input.
> At the moment I escape all dollar signs in the replacement values with "$$". This is annoying. Especially as I use one template with variables as a value for another variable. Here I have to escape twice.
> Here's some example code. At the moment it prints "Hello world". The commented line is my suggestion for this feature. If it works, it should print "Hello ${key2}":
> Map<String, String> valueMap = new HashMap<>();
> valueMap.put("key", "$${key2}");
> valueMap.put("key2", "world");
> String source = "Hello ${key}";
> StrSubstitutor strSubstitutor = new StrSubstitutor(valueMap);
> // strSubstitutor.setEnableSubstitutionInValues(false);
> System.out.println(strSubstitutor.replace(source));
