2009-10-21 blanchet 2009-10-21 merged
2009-10-21 blanchet 2009-10-21 removed "nitpick_const_simp" attribute from Record's "simps"; Nitpick has its own notion of a record and doesn't need those.
2009-10-21 haftmann 2009-10-21 curried inter as canonical list operation (beware of argument order)

2009-09-29 Thomas Sewell 2009-09-29 Replace OldTerm.term_vars with Term.add_vars in named_cterm_instantiate.
2009-09-28 Thomas Sewell 2009-09-28 Avoid a possible variable name conflict in instantiating a theorem. Instantiating a theorem variable with new variables created a possible variable name conflict if a record was defined with a field named 'f', 'x' etc. Using variable indices of 1 avoids the problem.
2009-09-23 tsewell 2009-09-23 Initial response to feedback from Norbert, Makarius on record patch As Norbert recommended, the IsTuple.thy and istuple_support.ML files have been integrated into Record.thy and record.ML. I haven't merged the structures - record.ML now contains Record and IsTupleSupport. Some of the cosmetic changes Makarius requested have been made, including renaming variables with camel-case and run-together names and removing the tab character from the Author: line. Constants are defined with definition rather than constdefs. The split_ex_prf inner function has been cleaned up.
2009-09-11 Thomas Sewell 2009-09-11 Implement previous fix (don't duplicate ext_def) correctly.
2009-09-11 Thomas Sewell 2009-09-11 There's no particular reason to duplicate the extension constant's definition under the name "ext_def", and it also prevents you having a field called ext.
2009-09-10 Thomas Sewell 2009-09-10 Simplification of various aspects of the IsTuple component of the new record package. Extensive documentation added in IsTuple.thy - it should now be possible to figure out what's going on from the sources supplied.
2009-09-10 Thomas Sewell 2009-09-10 Record patch imported and working.
