Hi Leif,
The latter idea (##) seems the most logical since most programming
conventions use a double whatever to escape and use the whatever!
Eg, in VB an & is used to specify an accelarator key in menus buttons etc,
so && escapes this and shows "&" in the menu button etc.
The only issue might be where people have a string of #'s used to highlight
an area of code in a conf file, eg
########################### IMPORTANT CODE ###########################.

Please respond to
wrapper-user
I have been looking into the options for how to make it possible to
include #
characters in a property value.
The problem is that property declarations like the following do not work
because
The Wrapper clips everything from the # as a comment.
wrapper.java.additional.1=-Dtest=my#test
The Wrapper sees the above as:
wrapper.java.additional.1=-Dtest=my
1) One option is to ignore # characters inside of quotes, but this
causes problems
on *NIX platforms. It is not possible to strip the quotes because
changing that
would cause compatibility problems with users who are already using quotes
and expecting them to remain unmodified by the Wrapper. So this is pretty
much a no-go.
2) Introduce an escape character to make it possible to escape the # when
it
should be included. The obvious escape character would be the backslash.
But I unfortunately can not use it because users have been using unescaped
backslash characters in their wrapper.conf files throughout the life of the
Wrapper. The option I am looking at right now for the escape character is
another # character. So 2 # characters would resolve into 1 in the actual
property value. It seems a little hackish and would not be usable in other
contexts if other characters ever need to be escaped in the future.
Currently, the ## option is the only one that is viable. Does anyone
have any
other ideas.
Using the above example,
wrapper.java.additional.1=-Dtest=my##test#Comment
Would resolve to:
wrapper.java.additional.1=-Dtest=my#test
Cheers,
Leif
