# Tree
This lib provides the tree datatype according to the [node 62][node62] from the
School of Informatics’ [Standard ML ’97 on-line tutorial][tutorial].
Depends on [MLton][mlton] with [SuccessorML][sML].
## Installing
Install [Smackage][smackage] and run:
```sh
smackage source tree git https://github.com/cacilhas/tree.git
smackage refresh
smackage get tree
```
## Usage
In your MLBasis add the entry:
```sml
$(SMACKAGE)/tree/v1/tree.mlb
```
### API and Examples
Creating a node:
```sml
val node = Tree.node(0, Tree.empty, Tree.empty)
```
The `Tree.node` expects a 3-element tuple: the value, the left node, and the
right node. `Tree.empty` is an empty node.
The *funs* that deals with nodes:
- `Tree.depth : 'a tree -> int` returns the tree depth
- `Tree.size : 'a tree -> int` returns the size of the tree
- `Tree.value : 'a tree -> 'a option` returns the value bound to the node
## Testing
Install [UnitTestML][unittestml] and [Pipelines][pipelines], and run:
```sh
mlton tests/test.mlb
./tests/test
```
