Guessing, since I didn't follow the discussion: nowhere.
<dependset> deletes the target files if it thinks they are outdated,
so the way dependset factors into the transformation is by removing
the target file and thus making it appear out of date WRT the source
file.
OK, got it. So it sounds like a DependSet is not appropriate for this
type of thing
* I will need to write to the file system to maintain the
cache. What would be a good way of handling this? Should I create a
directory in the baseDir for all transforms. Then a directory per
xslt task. Inside that dir create a properties file per transform?
How would you do it?
Make it an attribute with some reasonable default (your descriptions
sounds good, but how would you define "per xslt task"? use the
stylesheet's name?). See the <modified> selector for example.
The templates' URIResolver could work like the <modified> selector.
But the transformer's URIResolver is different. Since it is at a per
transform level it is not really the same (where the transform can
happen over all XML files in some src dir).
I would love to use a properties implementation that allowed getting a
subset of properties based on 'startsWith' see:
http://commons.apache.org/configuration/apidocs/org/apache/commons/configuration/AbstractConfiguration.html#getKeys(java.lang.String)
?? I did a search in the ant source and did not find
'org.apache.commons.configuration'
Example props file:
main1.xsl.templates.import1.xsl = 6873gf43gf
main1.xsl.templates.include1.xsl = 7fg34gry
main1.xsl.transformer.mainSource1.xml.abc.xml = 823478fr87134
main1.xsl.transformer.mainSource1.xml.foo.xml = 1y83gf8734
(probably using paths in the key names ??)
So, for example,
SomeImplOfAbstractConfiguration.getKeys("main1.xsl.templates") returns
the keys to check for the templates recomplile and to perform the
transform.
Is something like this available now in Ant? If not, would the commons
configuration be OK as a dependency? I bet it would be useful in other
places ??
Definitely open to ideas for this :)
* new class name TraxCachingLiason -- ideas?
CachingTraxLiaison - but then again, all badly chosen names in Ant are
mine (TM) ;-)
I used that name so it would show up next to TraxLiaison in the
javadoc :)
thanks for your input,
