## Representing State
|
|||
|
|
Leo allows users to define composite data types with the `struct` keyword.
|
|||
|
|
The game board is represented by a struct called `Board`, which contains three `Row`s.
|
|||
|
|
An alternative representation would be to use an array, however, these are not yet supported in Leo.
|
|||
|
|
|
|||
|
|
## Language Features
|
|||
|
|
- `struct` declarations
|
|||
|
|
- conditional statements
|
|||
|
|
- early termination. Leo allows users to return from a function early using the `return` keyword.
|
|||
|
|
|
|||
|
|
## Running the Program
|
|||
|
|
|
|||
|
|
Leo provides users with a command line interface for compiling and running Leo programs.
|
|||
|
|
Users may either specify input values via the command line or provide an input file in `inputs/`.
|
|||
|
|
|
|||
|
|
### Providing inputs via the command line.
|
|||
|
|
1. Run
|
|||
|
|
```bash
|
|||
|
|
leo run <function_name> <input_1> <input_2> ...
|
|||
|
|
```
|
|||
|
|
See `./run.sh` for an example.
|
|||
|
|
|
|||
|
|
|
|||
|
|
### Using an input file.
|
|||
|
|
1. Modify `inputs/tictactoe.in` with the desired inputs.
|
|||
|
|
2. Run
|
|||
|
|
```bash
|
|||
|
|
leo run <function_name>
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
## Executing the Program
|
|||
|
|
```bash
|
|||
|
|
leo execute <function_name> <input_1> <input_2> ...
|
|||
|
|
```
