Frontend AST is the first stage after parsing from source code, and has the closest resemblance to the Elm source code. Eg. all the comments etc. are still there.
{ modules : Dict Elm.Data.ModuleName.ModuleName (Elm.Data.Module.Module LocatedExpr) }
"What does this compiler stage need to store abotut the whole project?
(See Elm.Data.Project
.)
In this case, a dict of all the compiled Elm modules that hold frontend AST expressions.
Elm.Data.Located.Located Expr
The main type of this module. Expression with location metadata.
Note the underlying Expr
custom type recurses on this LocatedExpr
type,
so that the children also each have their location metadata.
If you want expressions without location metadata, look at unwrap
.
unwrap : LocatedExpr -> Unwrapped.Expr
Discard the location metadata.
transform : (Expr -> Expr) -> Expr -> Expr
Transform the expression using the provided function.
Start at the children, repeatedly apply on them until they stop changing, then go up.
recurse : (Expr -> Expr) -> Expr -> Expr
A helper for the Transform library. Runs the given function recursively on all children.
