13 This is a C++ library for **MAR**itime **NAV**igation purposes.
15 It supports (partially):

205 "$GPRMC,201034,A,4702.4040,N,00818.3281,E,0.0,328.4,260807,0.6,E,A*17");
206 std::cout << sentence->tag() << "\n";

217 std::string data = nmea::to_string(mtw);
220 ### Parse AIS Message from NMEA data
223 using namespace marnav;
225 // received sentences
226 const std::vector<std::string> received_strings
227 = {"!AIVDM,2,1,3,B,55P5TL01VIaAL@7WKO@mBplU@<PDhh000000001S;AJ::4A80?4i@E53,0*3E",
228 "!AIVDM,2,2,3,B,1@0000000000000,2*55"};
230 // parse NMEA sentences
231 std::vector<std::unique_ptr<nmea::sentence>> sentences;
232 for (auto const & txt : received_strings) {
233 auto sentence = nmea::make_sentence(txt);
234 if (sentence->id() == nmea::sentence_id::VDM) {
235 sentences.push_back(std::move(sentence));
239 // parse and and process AIS messags
240 auto payload = nmea::collect_payload(sentences.begin(), sentences.end());
241 auto message = ais::make_message(payload);
242 if (message->type() == ais::message_id::static_and_voyage_related_data) {

257 // ... most data not shown here
260 auto payload = ais::encode_message(pos_report);
262 // create NMEA sentences
263 for (uint32_t fragment = 0; fragment < payload.size(); ++fragment) {
265 vdm.set_n_fragments(payload.size());
266 vdm.set_fragment(fragment + 1);
267 vdm.set_radio_channel(nmea::ais_channel::B);
268 vdm.set_payload(payload[fragment]);
270 // collect, send or do something with the sentence...
271 std::string s = nmea::to_string(vdm);
272 std::cout << s << "\n";
281 This chapter describes the requirements in order to build the library.
282 Tools and their versions are listed below, newer/older/other tools
283 (i.e. compilers, etc.) may work, but not tested.
291 Tools needed to build the library:
294 Tools needed to develop the library:
298 Tools needed to build the documentation:
301 - LaTeX (there are formulas!)
303 Optional used for development:
304 - lcov / genhtml, c++filt
306 - clang-analyze (3.7 or newer)
309 Optional (no core dependency):
310 - Boost.ASIO (used only for some examples)
311 - Qt 5 (used only for some examples)
316 There are no other dependencies despite the standard library (C++11)
317 to build this library.
324 The following build types `-DCMAKE_BUILD_TYPE=x` are possible:
330 - `ENABLE_STATIC` : enables static build, if `OFF`, a shared library is being built.
332 - `ENABLE_WARNING_HELL` : enables _much_ more warnings, used for development purposes.
333 Currently implemented only for GCC. Default is `OFF`
334 - `ENABLE_PROFILING` : enables profiling
341 cmake -DCMAKE_BUILD_TYPE=Release ..
357 or individual package types:
363 ### Developpers Choice
367 cmake -DCMAKE_BUILD_TYPE=Coverage -DENABLE_WARNING_HELL=YES ..
369 make coverage doc cppcheck
372 ### Static Analysis with Clang
376 cmake -DCMAKE_CXX_COMPILER=/usr/share/clang/scan-build-3.7/c++-analyzer ..
377 scan-build-3.7 --use-analyzer=/usr/bin/clang++-3.7 make
379 After the build, ```scan-build``` will tell you what to do in order to inspect
385 There is a helper script ```bin/check-format``` which uses ```clang-format``` to
386 check the formatting of all files in the directories containing code (```src```,
387 ```test``` and ```examples```). This script can be used manually:
391 or used as git pre-commit hook:
394 ln -s ../../bin/check-format pre-commit
396 which prevents a commit if there are files not complying with the formatting
397 rules. Be aware of using the script as pre-commit hook, the checking can take
406 Mario Konrad (mario.konrad@gmx.net) with help from others.
