Hello Guillaume,
Thanks for your reply. However, if I escape the string the way you describe,
then the backslash will remain in the string. The result will be:
file://inbox?move=backup/$\{date:now:yyyMMdd\}/$\{file:name\}
What I want is:
file://inbox?move=backup/${date:now:yyyMMdd}/${file:name}
Otherwise the string will not be usable for Camel. Is there a way to
accomplish this? In general terms one usually has a way to "quote"
substrings in order to avoid substitution but the quotes themselves should
be removed from the string. In this case backslash is the quoting character
but it's not removed from the end result.
I think also that it would be good if one could escape substrings and not
only indiviudal characters (by enclosing substrings with quotes) but that
has lower priority for me if I can get the above to work.
I've been looking at the source code in file install (3.0) and understand
why this is happening. The method of interest is substVars in class
org.apache.felix.fileinstall.internal.Util. The logic tries to find
matching DELIM_START (${) and DELIM_STOP (}). When I escape either of these
(by specifying a backslash before "${" and/or "}"), the logic will never
find matching DELIM_START and DELIM_STOP which causes the method to
immediately return without performing property substitution. The logic at
the end of the method (that removes the backslashes) is never reached.
