Hi, This is an update to the validate.args package, which provides a framework for validation of function arguments and data structures. A few of the major changes since the last public release (1.0.1) are: * the validation engine now uses objects to encapsulate state and allows sub-classing of objects * hooks are provided to massage data before and after validation * A new module validate.inplace provides "live" validation of data during assignment to table elements The last addition makes validation more user-friendly by providing proxy tables which validate on the fly, so that a user can do something like config.foo = -3 and the assignment will throw an error if config.foo is only supposed to take positive numbers. A rockspec and a complete tarball are available here: https://bitbucket.org/djerius/validate.args/downloads/validate-args-1.2.4-1.rockspec https://bitbucket.org/djerius/validate.args/downloads/validate-args-1.2.4.tar.gz A more detailed list of changes is here: https://bitbucket.org/djerius/validate.args/src/8b47ced5e539/NEWS
