------------------------------------------
Summary: StrSubstitutor: Ability to turn off substitution in values
Key: LANG-867
URL: https://issues.apache.org/jira/browse/LANG-867
Project: Commons Lang
Issue Type: Improvement
Components: lang.text.*
Reporter: Arend v. Reinersdorff
Priority: Minor
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));
