# `light-cli`

A lightweight and heapless command line interface / command passing tool. Probably more useful for machine to machine communication.

## [Documentation](https://rudihorn.github.io/light-cli/light_cli/)

## [Example]

The following definition allows for the commands:

* `HELLO Name=`: Set the name to ``

* `EHLO`: Return the name

```

lightcli!(cl_in, cl_out, cmd, key, val, [

  "HELLO" => [

    "Name" => name = String::from(val)

  ] => { writeln!(cl_out, "Name set").unwrap(); };

  "EHLO" => [

  ] => { writeln!(cl_out, "EHLO Name={}", name.as_str()).unwrap(); }

]);

```

A typical serial communication could look like:

```

>> EHLO

<< EHLO Name=

>> HELLO Name=Johnson

<< Name set

>> EHLO

<< EHLO Name=Johnson

```

It is recommended to use this in conjunction with the program [`rlwrap`](https://linux.die.net/man/1/rlwrap).

[Complete Example](https://github.com/rudihorn/light-cli/tree/master/examples/)

## What works

- Read key value style commands in the form:

  `COMMAND KEY=VALUE`

- UTF-8 encoding.

- Specify the heapless string length.

- Partial command evaluation as data is received through the serial connection.

## TODO

- [X] Writing to output

- [ ] Improve UTF-8 error detection / code.

- [ ] Any form of autocompletion / backspaces etc.
