2019-03-08some options, renamingJosh Chen1-0/+1
2019-03-03Improve automated handling of universes. derive now can automatically handle ↵Josh Chen1-0/+10
more proofs requiring the use of "U i: U (Suc i)", and shouldn't loop as much.
2019-02-28tweak mixfix prioritiesJosh Chen1-2/+2
2019-02-281. Remove all type inference functionality (feature development moving to ↵Josh Chen1-1/+10
another branch). 2. Eq.thy complete.
2019-02-17Method "quantify" converts product inhabitation into Pure universal ↵Josh Chen1-5/+8
statements. Also misc. cleanups.
2019-02-11Put typing functionality into a .thy and clean up antiquotations, which ↵Josh Chen1-47/+6
results in some reorganization of the theory import structure.
2019-02-10restructure libraryJosh Chen1-2/+2
2019-02-10Explicit references in antiquotations in typing.ML. Move trace switch ↵Josh Chen1-0/+3
definition to HoTT_Base.
2019-02-10Type information storage functionality (assume_type, assume_types keywords) ↵Josh Chen1-4/+34
done! Inference and pretty-printing for function composition done.

2019-02-041. Change syntax to rely less on unicode/control symbols.Josh Chen1-12/+53
2. Begin work on object-level type inference and input syntax help.

2018-07-12Unit and Null types. Methods.Josh Chen1-1/+2
2018-07-11Universes implemented. Type rules modified accordingly. No more automatic ↵Josh Chen1-23/+12
derivation of "A:U" from "a:A".

2018-07-07Library snapshot. Methods written, everything nicely organized.Josh Chen1-1/+1
2018-07-06Added attributes to type elimination rules, not sure if these will actually ↵Josh Chen1-3/+7
be needed or useful later. Added [comp] attribute to be used by simplification met methods.
2018-07-03Refactor HoTT_Methods.thy, proved more stuff with new methods.Josh Chen1-1/+3
2018-07-03Rewrote methods: wellformed now two lines, uses named theorems. New, more ↵Josh Chen1-4/+5
powerful derive method. Used these to rewrite proofs.

Added type formation rules expressing necessity of the conditions.
2018-06-18Removed all [simp] attributes, these will be added later when I set up the ↵Josh Chen1-1/+1
simplifier. Proved simplification rule for dependent fst.
