Andrew Jackson commented on TIKA-847:
-------------------------------------
Under TIKA-86, @kkrugler suggested we use the Lucene FSM RegEx engine (see
https://issues.apache.org/jira/browse/LUCENE-1606 and
http://search-lucene.com/jd/lucene/org/apache/lucene/search/RegexpQuery.html).
However, I believe this code is not yet in a stable Lucene version
(4.0-SNAPSHOT only) and so would rather we defer that optimisation to a later
date (under a separate ticket).

> Key: TIKA-847
> URL: https://issues.apache.org/jira/browse/TIKA-847
> Project: Tika
> Issue Type: New Feature
> Components: mime
> Affects Versions: 1.0
> Reporter: Andrew Jackson
> Labels: detection, format
>
> Following on from TIKA-86, we would like to add support for regular
> expressions to the MagicDetector. This would allow more signatures to be
> re-used from more sources (e.g. the file(1) command). As part of the SCAPE
> Project, we have added this functionality to our own Tika branch (e.g.
> https://github.com/openplanets/tika/commit/b8de9e77c8b432788e3f73a4dbccca8ea044b503)
> and are working to tidy this up to make a clean patch we can submit here.
> BTW, are there any patch submission guidelines or coding standards we should
> check our work against first?
