Data Processor   

Pebble library to extract strings, ints and booleans from a long string of data.

Installation

You must be using Pebble SDK 3.12 or newer to use this library.

To install the package to your app, use the pebble tool:

pebble package install @smallstoneapps/data-processor

Usage

// This is not a complete example, but should demonstrate
// the basic usage of Data Processor.

static void parse_data(char* data) {
  ProcessingState* state = data_processor_create(data, '|');
  uint8_t num_strings = data_processor_count();
  char** strings = malloc(sizeof(char*) * num_strings);
  for (uint8_t n = 0; n < num_strings; n += 1) {
    strings[n] = data_processor_get_string(state);
  }
}

Tests

Unit tests for Data Processor exist in the tests folder.

To run the tests:

make test
