chore(*): minimize dependencies on tests Signed-off-by: Leonardo de Moura <leonardo@microsoft.com> 2014-08-25 02:58:48 +00:00			`import logic`
feat(frontends/lean): rename 'using' command to 'open' Signed-off-by: Leonardo de Moura <leonardo@microsoft.com> 2014-09-03 23:00:38 +00:00			`open tactic (renaming id->id_tac)`
feat(frontends/lean): add repeat tactic command, refactor tactic sequence notation Signed-off-by: Leonardo de Moura <leonardo@microsoft.com> 2014-06-29 19:24:13 +00:00
			`definition id {A : Type} (a : A) := a`

refactor(*): rename Bool to Prop Signed-off-by: Leonardo de Moura <leonardo@microsoft.com> 2014-07-22 16:43:18 +00:00			`theorem tst {A B : Prop} (H1 : A) (H2 : B) : id A`
refactor(library/tactic/unfold_tactic): use new 'tactic.expr' to implement 'unfold' tactic This change also enabled us to remove hacks used in the tests modified by this commit. 2014-10-23 16:48:53 +00:00			`:= by !(unfold id; state); assumption`
feat(frontends/lean): remove build_tactic_cmds, and use expressions for representing tactics Signed-off-by: Leonardo de Moura <leonardo@microsoft.com> 2014-07-02 03:43:53 +00:00
