v0.7.2 Changes
March 09, 2020 ๐ Fixes #44 infinite loop due to boxed equality

v0.7.1 Changes
February 06, 2020 
v0.7 Changes
August 26, 2019 Require KnownNat constraints when solving with constants

v0.6.2 Changes
July 10, 2018 โ Add support for GHC 8.6.1alpha1
 Solve larger inequalities from smaller inequalities, e.g.
a <= n
impliesa <= n + 1

v0.6.1 Changes
May 09, 2018 Stop solving
x + y ~ a + b
by asking GHC to solvex ~ a
andy ~ b
as this leads to a situation where we find a solution that is not the most general.  Stop using the smallest solution to an inequality to solve an equality, as this leads to finding solutions that are not the most general.
 Solve smaller inequalities from larger inequalities, e.g.
1 <= 2*x
implies1 <= x
x + 2 <= y
impliesx <= y
and2 <= y
 Stop solving

v0.6 Changes
April 23, 2018 Solving constraints with
ab
will emitb <= a
constraints. e.g. solvingn1+1 ~ n
will emit a1 <= n
constraint. If you need subtraction to be treated as addition with a negated operarand
run with
fpluginopt GHC.TypeLits.Normalise:allownegatednumbers
, and theb <= a
constraint won't be emitted. Note that doing so can lead to unsound behaviour.
 If you need subtraction to be treated as addition with a negated operarand
run with
 Try to solve equalities using smallest solution of inequalities:
 Solve
x + 1 ~ y
using1 <= y
=>x + 1 ~ 1
=>x ~ 0
 Solve
 Solve inequalities using simple transitivity rules:
2 <= x
implies1 <= x
x <= 9
impliesx <= 10
 Solve inequalities using simple monotonicity of addition rules:
2 <= x
implies2 + 2*x <= 3*x
 Solve inequalities using simple monotonicity of multiplication rules:
1 <= x
implies1 <= 3*x
 Solve inequalities using simple monotonicity of exponentiation rules:
1 <= x
implies2 <= 2^x
 Solve inequalities using powers of 2 and monotonicity of exponentiation:
2 <= x
implies2^(2 + 2*x) <= 2^(3*x)
