TOML Expression Elaboration

Elaborates top-level TOML syntax into a Lean Toml.Table.

inductive Lake.Toml.KeyTy : Type

The manner in which a TOML key was declared.

• value : KeyTy

  A key declared via key = v.

• stdTable : KeyTy

  A key declared via [key].

• array : KeyTy

  A key declared via [[key]].

• dottedPrefix : KeyTy

  A key declared via key.foo.

• headerPrefix : KeyTy

  A key declared via [key.foo] or [[key.foo]].

Equations

• Lake.Toml.instInhabitedElabState = { default := { keyTys := default, arrKeyTys := default, arrParents := default, currArrKey := default, currKey := default, items := default } }

def Lake.Toml.mkSimpleTable (items : Array Keyval) : Table

Construct a table of simple key-value pairs from arbitrary key-value pairs.

For example:

{a.b := [c.d := 0]}, {a.b := [c.e := 1]}

becomes

{a := {b := [{c := {d := 0, e := 1}}]}}
