light-cli

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

Documentation

[Example]

The following definition allows for the commands: * HELLO Name=<Name>: Set the name to <Name> * 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.

Complete Example

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.
