|
|
This module offers a high-level and functional interface to the Format module of
|
|
the OCaml standard library. It is a pretty-printing facility, i.e. it takes as
|
|
input some code represented as a tree and formats this code into the most
|
|
visually satisfying result, breaking and indenting lines of code where
|
|
appropriate.
|
|
|
|
Input data must be first modelled and converted into a tree using 3 kinds of
|
|
nodes:
|
|
|
|
* atoms
|
|
* lists
|
|
* labelled nodes
|
|
|
|
Atoms represent any text that is guaranteed to be printed as-is. Lists can model
|
|
any sequence of items such as arrays of data or lists of definitions that are
|
|
labelled with something like "int main", "let x =" or "x:".
