to schema

Entry -> Schema

if entry has no `_:_` return {}
for each trunk of entry except _
  for each leaf of entry.trunk
    append trunk to schema.leaf.trunks
    append leaf to schema.trunk.leaves
return schema

is connected

Schema -> Base -> Branch -> Boolean

This tells if a branch is connected to base branch.

if branch equals base
  return true
for each trunk of branch
  if trunk equals base
    return true
  if trunk is connected to base
    return true
otherwise
  return false

find crown

Schema -> Base -> List Branch

This finds all branches that are connected to the base branch.

if leaf is connected to base
  return leaf

get nesting level

Schema -> Branch

for each trunk of branch
  get nesting level of trunk
  increment level

sort nesting ascending

Schema -> (Branch -> Branch -> Ordering)

sort by level of nesting, twigs and leaves come first

test cases

• • schema: record schema array
  • initial:
  • expected:

sort nesting descending

Schema -> (Branch -> Branch -> Ordering)

sort by level of nesting, trunks come first
