nmea-parse

Parses NMEA 0183 sentences (particularly from GPS receivers).

The output is a set of populated Google Protocol Buffer messages. The architecture is plugin-able to easily add or remove processing of specific NMEA sentences.

Build + test

This is really intended to be an API, so the executable built is just a test parser tool that reads NMEA lines from stdin and spits debug info to stdout.

To build:

$ make

To test:

$ cat gps.txt | bin/start

You'll see it echo each line from gps.txt and then output some info about what it's down to parse it. If parsing was successful, it will print the contents of the resulting packed .proto file.

To-do's

1. Build system upgrade to CMake so it will build easily on multiple architectures and double-check for dependencies

2. Abstract out common ASCII-text-parsing helpers

3. Perhaps parse the .proto and auto-generate code to parse the corresponding CSV line. Or have an XML definition auto-populate the corresponding .proto (not all info need be present in .proto). Then defining new message parsing is as easy as making a new XML file.
