Hello,
thanks for mentioning jexl scripting.
I tried it out and have found the following issue:
evaluating the following:
test=${expr:if (System.getProperty("user.home").startsWith("C"))
{"x";} else {"z";}}
does not seem to work.
Debuging shows that the expression forwarded to jexl is:
if (System.getProperty("user.home").startsWith("C")) {"x";
is this a bug ? or is there a way to escape the brackets within $
{...} ?
The "bug" is actually the way
org.apache.commons.lang.text.StrSubstitutor works. It can configured
be with prefix and suffix characters - the defaults are '{' and '}'
and after finding the prefix it just searches for the first occurance
of the suffix character - unless it finds a recursive variable. So the
string passed to ConfigurationInterpolator is what you show above.
However, it might be possible to override the suffix matcher to look
for an escape character.
