Catman...x::eval(3pm)

💖 NAME 💖

Catmandu::Fix::eval — bestie, this one evals and runs fixes that you defined inside a field ✨

It's giving "fixes inside your fixes", and honestly? iconic 🎀

🌸 SYNOPSIS 🌸

    # {fixes => 'add_field(foo,bar)'}
    eval(fixes)
    # {fixes => 'add_field(foo,bar)', foo => 'bar'}

    # {fixes => ['add_field(foo,bar)','upcase(foo)'], foo => 'bar'}
    eval(fixes)
    # {fixes => ['add_field(foo,bar)','upcase(foo)'], foo => 'BAR'}

okay so the vibe check here: you hand eval a field named fixes, and it literally takes whatever fixes are chillin' in there and executes them 🫶

• fixes is a string → it's one single fix, and it runs. In the example, add_field(foo,bar) gets evaluated, and boom, foo => 'bar' shows up in your record 💅
• fixes is an array → it's a whole list of fixes, and they all run, in order. In the example, add_field(foo,bar) runs and then upcase(foo) runs, so foo => 'bar' becomes foo => 'BAR' 🔥

no cap, that's the whole thing. the fixes live in your data, and eval is the one that makes them happen ✨
