2013-04-29	Splitting Term into five unrelated interfaces:	ppedrot
	1. sorts.ml: A small file utility for sorts; 2. constr.ml: Really low-level terms, essentially kind_of_constr, smart constructor and basic operators; 3. vars.ml: Everything related to term variables, that is, occurences and substitution; 4. context.ml: Rel/Named context and all that; 5. term.ml: derived utility operations on terms; also includes constr.ml up to some renaming, and acts as a compatibility layer, to be deprecated. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16462 85f007b7-540e-0410-9357-904b9bb8a0f7
2013-04-17	Improving error message in explain_cannot_find_well_typed_abstraction:	herbelin
	make head bound variables distinct from the variables in environment, so that the naming scheme is the same when, say, printing "fun x:B => foo x" in environment "x:A" (main error with explicit "fun") and when printing (secondary error in the "reason" message) "foo x" in environment "x:A, x:B" (i.e. with "fun" discharged in environment). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16415 85f007b7-540e-0410-9357-904b9bb8a0f7
2013-03-21	Robust display of NotConvertibleTypeField errors (fix #3008, #2995)	letouzey
	Since the nametab isn't aware of everything needed to print mismatched types (cf the bug test-cases), we create a robust term printer that known how to print a fully-qualified name when [shortest_qualid_of_global] has failed. These Printer.safe_pr_constr and alii are meant to never fail (at worse they display "??", for instance when the env isn't rich enough). Moreover, the environnement may have changed between the raise of NotConvertibleTypeField and its display, so we store the original env in the exception. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16342 85f007b7-540e-0410-9357-904b9bb8a0f7
2013-02-17	Added propagation of evars unification failure reasons for better	herbelin
	error messages. The architecture of unification error handling changed, not helped by ocaml for checking that every exceptions is correctly caught. Report or fix if you find a regression. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16205 85f007b7-540e-0410-9357-904b9bb8a0f7

2012-07-11	A friendlier printing of remaining goals when no goal is focused.	aspiwack
	Only their conclusion is printed (with a "subgoal n" header) like every goal but the first in the usual case. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15591 85f007b7-540e-0410-9357-904b9bb8a0f7
2012-07-04	Change how the number of open goals is printed.	aspiwack
	If you are focused on 3 subgoals, and unfocusing would reveal 2 extra subgoals, and unfocusing again would reveal 4 extra subgoals, then coqtop will tell you: 3 focused subgoals (unfocused: 2-4) git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15508 85f007b7-540e-0410-9357-904b9bb8a0f7
