maths in grc formulas

[withnale]

Is there any way to write a formula that can make use of arithmetic functions, or is there a clean way of implementing this a new feature?

One example case springs to mind using grc with kubectl

NAME       READY   UP-TO-DATE   AVAILABLE   AGE
api1       1/1     1            1           33d
ui         1/1     1            1           33d
api2       2/2     2            1           33d
auth       3/4     1            1           33d
client     0/1     1            1           33d
event      1/1     1            1           33d
postgres   2/2     2            2           33d

In the above example:

• both client and auth are in error because their READY column has is 0/1 and 3/4
• api2 is also in error because only 1 of the 2 instances are up-to-date

grc is able to forward the found text to a program, maybe, you can fiddle around with this.
