* general tests for the helper feature (thlp*) * tests for class helpers (tchlp*) * tests for record helpers (trhlp*) With my current yet-to-be-commited implementation nearly all tests pass, but some fail because of missing FPC features: * thlp30.pp currently fails because of generic constraints, but should fail despite the constraints * thlp29.pp fails, because generic methods are not yet supported * trhlp8.pp, trhlp9.pp, trhlp10.pp fail, because one can't use default properties using the abbreviated syntax * trhlp17.pp, trhlp18.pp, trhlp19.pp fail, because nested types are not supported for records git-svn-id: branches/svenbarth/classhelpers@17237 -
