Morning folks π
G'day
Morning all π
Spent a couple hours yesterday retrofitting schemaβs defn
macro to work with malli instead
Mind sharing how? Im curious because Im starting to play around with malli myself. Also, what are your thoughts on spec 2?
Grabbed the schema macros and modified them to use malli instead
That's honestly it π
Was actually fairly painless, just a bit of thinking
As for spec2, I've only glanced at it but I'm still not sold
Putting things in a registry and needing a separate fdef, both make it harder to read things
Oh right. How did you go about instrumenting with malli? (Assuming you do)
Not specifically instrumenting. So spec has its instrument for replacing a function with a version with the fdef applied.
Schema's version is to declare it on the defn itself with some optional symbol :- type
syntax, then switch it on with a global var
There's also a switch for not allowing compilation at all, so it just adds the raw defn without any checking (basically elide asserts)
Plus it constructs the equivalent of fdef while you're at it
Reading schema's docs (Ive not used it before) :-
seems to be just for type hints, is that right?
Basically yeah. Although it also attaches pre/post maps validating those types when checking is on
