chore(builtin): rename nat, int and real modules to Nat, Int and Real. Signed-off-by: Leonardo de Moura <leonardo@microsoft.com> 2014-01-01 21:52:25 +00:00			`Import Int.`
feat(lua): allow Lua scripts to update 'global' options Signed-off-by: Leonardo de Moura <leonardo@microsoft.com> 2013-11-12 23:38:00 +00:00			`Variable x : Int`
feat(frontends/lean): rename command Set to SetOption It is not nice to have Set as a reserved keyword. See example examples/lean/set.lean Signed-off-by: Leonardo de Moura <leonardo@microsoft.com> 2013-12-19 05:18:45 +00:00			`SetOption pp::notation false`
feat(lua): use ( ... ) instead of {{ ... }} for nested Lua scripts The token }} is a bad delimiter for blocks of Lua script code nested in Lean files. The problem is that the sequence }} occurs very often in Lua code because Lua uses { and } to build tables/lists/arrays. Here is an example of Lua code that contains the sequence }} t = {{1, 2}, {2, 3}, {3, 4}} In Lean, (* ... ) is used to create comments. Thus, (* ... **) code blocks will not affect valid Lean files. It also looks reasonably good. Signed-off-by: Leonardo de Moura <leonardo@microsoft.com> 2013-11-13 00:05:46 +00:00			`(**`
