Token Filters Questions

[Aaron Davies <aa...@gmail.com>]

A couple questions on token filters:

First, is there a simple way to directly apply a filtersfile to an
existing file, i.e. without moving/copying it?

Second, is there an easy way to handle a filtersfile's not existing?
I'd like to run a file through multiple filters, not all of which will
actually exist, but the only way I can see to do that right now is to
either wrap multiple copy-filter statements in available tests or to
do the full truth table on all the filters and use it to generate the
correct filterset. There's got to be a better option.

I've decided to go with option three: commit empty filter files to
svn. The problem with option two is that we want to run our files past
multiple filters, each of which may or may not exist, and doing this
with if statements is extremely difficult. The problem with option one
is that I'm lazy. ;-)

The way I see it, there's two solutions:
1. Take the source for FiltersFile, and change the exception section, which
doesn't fit you.
2. Check if the file exists, prior to it (using the <IF> tags in the
expansion pack, ant-contrib, I think) and then activate FiltersFile.

If the filter is done with a property file <filtersfile
file="filter.properties"/> and the property file doesn't exist, an
exception is thrown. Is there a way to do more graceful degradation?

I'm not sure I understood your question: How can a filter not exist? Can you
give an example?
