Strict checkAndEvaluateMath

[floscr]

Adds a strict version of checkAndEvaluateMath which is being evaluated by https://github.com/tokens-studio/unit-Calculator/

This will allow users to specify stricter rules on which units they want to mix, in the case of Penpot only rem and px units are allowed as units and to mix with a predefined conversion value.

Besides doing proper unit parsing, it also gets rid of a bunch of wrapped regexes around expr-eval-fork that try to do things like group splitting, removing and putting back of units, etc. Instead a proper parser will be used to evaluate expressions.

There are a bunch of functions in expr-eval that we might want to restore, I've added an example with roundTo here:

sd-transforms/src/strictCheckAndEvaluateMath.ts

Line 12 in 9b27a73

export const defaultCalcConfig = {

strict math can be enabled by setting mathOptions in the platform config.
