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

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

cargo build --example stm32 --target thumbv7m-none-eabi

• 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.

• Writing to output
• Improve UTF-8 error detection / code.
• Any form of autocompletion / backspaces etc.
