[xwiki-devs] [proposal] Enable some commons-lang classes as velocity tools

Hi devs, I'd like to enable some classes from the commons-lang library as velocity tools. As a reminder, a velocity tool is an object that is placed in the velocity context, and which can be used to perform some actions. The tool should be stateless and thread-safe, as the same object is used for all requests. There is the VelocityTools library, which contains some useful tools, but I think those are not enough. So, I'd like to enable StringUtils, WordUtils, RandomStringUtils, StringEscapeUtils, BooleanUtils, ArrayUtils, math.NumberUtils, math.RandomUtils, time.DateUtils, time.DateFormatUtils Given the fact that tools are only create once, there won't be any memory issue. And I think that these tools are wide enough to discourage any attempt to add nice methods to the XWiki class, and will allow to deprecate utility methods in the XWiki API, and remove the Util API. Any objections? Any other classes we should enable? -- Sergiu Dumitriu http://purl.org/net/sergiu/
