2009-09-28 Thomas Sewell 2009-09-28 Fix unescaped expressions breaking latex output in Record.thy Expressions containing _ and ^ need to be adjusted or antiquoted in text comments for latex compatibility. This is in fact a little annoying, since it makes the comment less readable in both source and HTML form.
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.
2009-09-10 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.
