omega.int.exprform → tactic omega.int.preform

Reification to an intermediate shadow syntax which eliminates exprs, but still includes non-canonical terms

source
meta def omega.int.to_preform (x : expr) :

meta def omega.int.prove  :
tactic expr

Return expr of proof of current LIA goal

source
meta def omega.int.eq_int (x : expr) :

Succeed iff argument is the expr of ℤ

source
meta def omega.int.wff  :
expr → tactic unit

Check whether argument is expr of a well-formed formula of LIA

meta def omega.int.intro_ints  :
tactic unit
source
meta def omega.int.preprocess  :
tactic unit

If the goal has universal quantifiers over integers, introduce all of them. Otherwise, revert all hypotheses that are formulas of linear integer arithmetic.
