	Commit message (Collapse)	Author	Files	Lines
2018-08-16	Prod.thy now has the correct definitional equality structure rule. ↵	Josh Chen	1	-17/+11
	Definition of function composition and properties.
2018-08-15	Rename to distinguish function and path composition; function composition ↵	Josh Chen	1	-8/+18
	proofs, which have issues...
2018-08-15	Basic compute method	Josh Chen	1	-1/+1

2018-08-15	Tweak proof methods, some type rules; add HoTT Book examples	Josh Chen	1	-1/+1

2018-08-15	Function composition, rename path composition to differentiate the two.	Josh Chen	1	-0/+16

2018-08-13	rcompose done	Josh Chen	1	-14/+8

2018-08-12	Commit before testing polymorphic equality eliminator	Josh Chen	1	-10/+12

2018-08-07	Old application syntax incompatible with Eisbach	Josh Chen	1	-6/+6

2018-08-07	Experiment with polymorphic dependent eliminators, i.e. we leave type and ↵	Josh Chen	1	-5/+5
	type family decorations implicit.
2018-08-06	Partway through changing function application syntax style.	Josh Chen	1	-17/+17

2018-08-04	Reorganize theories	Josh Chen	1	-26/+30

2018-07-12	Unit and Null types. Methods.	Josh Chen	1	-0/+19

2018-07-11	Universes implemented. Type rules modified accordingly. No more automatic ↵	Josh Chen	1	-4/+4
	derivation of "A:U" from "a:A".
2018-07-07	Library snapshot. Methods written, everything nicely organized.	Josh Chen	1	-0/+1

2018-07-06	Remove extra attributes for elimination rules, unneeded for now.	Josh Chen	1	-2/+1

2018-07-06	Added attributes to type elimination rules, not sure if these will actually ↵	Josh Chen	1	-0/+2
	be needed or useful later. Added [comp] attribute to be used by simplification met methods.
2018-07-04	Trivial changes	Josh Chen	1	-1/+1

2018-07-03	Rewrote methods: wellformed now two lines, uses named theorems. New, more ↵	Josh Chen	1	-2/+1
	powerful derive method. Used these to rewrite proofs.
2018-06-30	Proving path composition. Need to set up the Simplifier to simplify ↵	Josh Chen	1	-0/+1
	application of object-lambdas to arguments.
2018-06-30	Finished proofs of projections	Josh Chen	1	-1/+1

2018-06-18	Fixed wrong definition of snd_dep. Proved projection property of snd_dep. ↵	Josh Chen	1	-5/+13
	Added type formation rules expressing necessity of the conditions.
2018-06-18	Removed all [simp] attributes, these will be added later when I set up the ↵	Josh Chen	1	-12/+19
	simplifier. Proved simplification rule for dependent fst.
2018-06-17	Decided on a new proper scheme for type rules using the idea of implicit ↵	Josh Chen	1	-1/+1
	well-formed contexts and guaranteed conclusion well-formedness. Product type rules now follow this scheme.
2018-06-12	Type rules now have \"all\" premises explicitly stated, matching the ↵	Josh Chen	1	-6/+13
	formulation in the HoTT book.
2018-06-09	Reorganize code	Josh Chen	1	-0/+48
