🌸 NAME 🌸

Catmandu::Fix::Bind::list — a binder that computes Fix-es for every element in a list

like. it's a binder. it binds. it does the thing to every single item in your list. iconic behavior honestly 👑

---

✨ SYNOPSIS ✨

# Create an array:
#  demo:
#    - red
#    - green
#    - yellow

# Add a foo field to every item in the demo list, by default all
# fixes will be in context of the iterated path. If the context
# is a list, then '.' will be the path of the temporary context
# variable
do list(path:demo)
   if all_equal(.,green)
       upcase(.)
   end
end

# This will result:
#  demo:
#    - red
#    - GREEN
#    - yellow

# Loop over the list but store the values in a temporary 'c' variable
# Use this c variable to copy the list to the root 'xyz' path
do list(path:demo,var:c)
   copy_field(c,xyz.$append)
end

# This will result:
#  demo:
#    - red
#    - GREEN
#    - yellow
#  xyz:
#    - red
#    - GREEN
#    - yellow

so like, watch the green become GREEN. that's the glow-up fr fr 💅

🦋 DESCRIPTION 🦋

The list binder will iterate over all the elements in a list and fixes the values in context of that list.

translation bestie: it goes one by one through every element, no skipping, no shortcuts, and applies your fixes in the context of that list. main character energy for each item 🌈

---

🎀 CONFIGURATION 🎀

🌟 path

The path to a list in the data.

💫 var

The loop variable to be iterated over. When used, a magic temporary field will be available in the root of the record containing the iterated data.

✨ "magic temporary field" is a direct quote, not me being dramatic for once. it lives in the root of the record, and it's holding your iterated data. treat it with respect 🫶
