2020-10-03cleanup: make device code more consistent with coreGravatar Berthold Stoeger
We keep track of device, i.e. distinct dive computers with id in the core. The corresponding code stuck out like a sore thumb. Firstly, because it is C++. But more importantly, because it used inconsistent nameing conventions. Notably it defined a "DiveComputerNode" when this is something very different from "struct dive_computer", the latter being the dive-computer related data of a single dive. Since the whole thing is defined in "device.h" and the function to create such an entry is called "create_device_node", call the structure "device". Use snake_case for consistency with the other core structures. Moreover, call the collection of devices "device_table" in analogy with "dive_table", etc. Overall, this should make the core code more consistent style-wise.

2020-10-03cleanup: use getDCExact() instead of callback in set_dc_deviceid()Gravatar Berthold Stoeger
core/device.c used to be a C file, which couldn't access the C++ divecomputer list directly. Therefore, instead of a simple loop, searching for a matching DC was implemented via a callback with void * user data parameter. Wild. Since the file is now C++, let's just use direct access to the C++ data structures to make this readable by mere humans. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2020-10-03cleanup: pass divecomputer to getDC() and getDCExact() helpersGravatar Berthold Stoeger
These are used to search for device nodes and were passed model and device id (for the exact version). However, all callers used them to search for the node corresponding to a specific struct divecomputer, so let's just pass that instead to make the caller site less complex.

2020-10-03cleanup: hide DiveComputerList implementation detailsGravatar Berthold Stoeger
Remove the declaration of helper functions needed only in core/device.cpp. To this goal, turn the member functions into free functions. Cosmetics: turn the DiveComputer[Node|List] "class"es into "struct"s, since all members were public anyway. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2020-10-03cleanup: use getDiveSelection() to loop over selected divesGravatar Berthold Stoeger
getDiveSelection() returns a vector of the selected dives. Use that instead of looping over the dive table and checking manually. This removes a few lines of code. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
2020-09-13cleanup: fold core/divecomputer.cpp into core/device.cGravatar Berthold Stoeger
core/device.h was declaring a number of functions that were related to divecomputers (dcs): creating a fake dc for manually entered dives and registering / accessing dc nicknames. On could argue whether these should be lumped together, but it is what it is. However, part of that was implemented in C++/Qt code in a separate core/divecomputer.cpp file. Some function therein where only accessible to C++ and declared in core/divecomputer.h. All in all, a big mess. Let's simply combine the files and conditionally compile the C++-only functions depending on the __cplusplus define. Yes, that means turning device.c into device.cpp. A brave soul might turn the C++/Qt code into C code if they whish later on. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
