This actually gets me far enough that it prints out all the dives on my
dive computer. It doesn't actually turn them into real dives yet,
though - only a series of ugly 'printf's so far.
And it hangs after printing the last dive. So I'm doing something wrong.

.. this now registers the dive parsing callback, and starts to parse the
data. So I can see the last divetime on my Suunto Vyper Air now.
Still a lot more boilerplate stuff to go, though. The libdivecomputer
interfaces really are pretty insane: why should the caller set up the
dive parsing for each computer type, when libdivecomputer knows what
types it has? IOW, much of that boilerplate should be hidden inside of
libdivecomputer, rather than exposed to the user.
But whatever. I'm taking pieces from "examples/universal.c" as I go
along (it's under LGPL 2.1). I want to do it in small chunks just to
feel that I understand what's going on, rather than just blindly copying

Ok, so this is quite broken right now: it doesn't actually really *do*
anything, and it now requires that you have libdivecomputer all set up
and installed.
That is fairly easy:
mkdir ../src
cd ../src
git clone git://libdivecomputer.git.sourceforge.net/gitroot/libdivecomputer/libdivecomputer
cd libdivecomputer
autoreconf --install
./configure
make
sudo make install
but you may feel that this is not exactly useful considering that
nothing actually *works* yet.

The Diving Log temperature reading is in Fahrenheit for the samples (for
the per-dive water/air temperature it's in Celsius). But it seems to
have a bug where a lack of a sample has been turned into 32 Fahrenheit
(which is 0 celsius). This is despite the dive itself having a water
temperature of 8 degF.
Just throw away those bogus freezing temperatures. Sure, they can
happen, and ice divers are crazy - but in this case I know it's just an
error in the log, and it looks very much like a Diving Log bug.

The LP85+ name is not something we'd normally want to recognize. The LP
cylinder names all tend to be by the "+" pressure anyway, and that's
what we do in the equipment handling naming.
Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
When we change units, we need to flush any currently active dive
information in the old units, and then carefully reload it in the new
units.
Otherwise crazy stuff happens - like having current cylinder working
pressure values that are in PSI because that *used* to be the output
unit, but then interpreting those values as BAR, because we changed the
units.
Also, since we now properly import working pressure from Diving Log,
stop importing the (useless) cylinder description. The Diving Log
cylinder descriptions are things like "Alu" or "Steel". We're better
off just making up our own.
Finally, since Diving Log has cylinder size in metric, make sure that we
do the "match standard cylinder sizes" *after* we've done all the
cylinder size conversions to proper units.

Oh Gods. Why are all other scuba programs so f*&% messed up?
The Diving Log cylinder working pressure is in bar - which is all good.
But their pressure *samples* are in PSI. Why the h*ll do people mix up
units in the same damn file like that? I despair at the pure
incompetence sometimes.
I suspect the pressure samples aren't "really" in PSI: they are probably
in some user-specified units.

Some people want to know how many dives they have under their belt, so
let's save and restore the dive number if it exists.
Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
This adds a few more predefined cylinder types to the static list, but
perhaps more importantly, if we try to show a cylinder description that
we haven't seen before, we automatically add that description to the
list as well.
This way, if people have their own cylinder types, our cylinder
management will automatically figure them out and make it easy to enter
them.
NOTE! It might be best to add the new cylinder description at dive log
load time, rather than at 'show' time.
Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
We also need to actually fill the model store with the cylinder models
we have in our dive lists to begin with.
This makes it all *trivial* to add a new cylinder model: just use a new
description, fill in the size and working pressure, and you're done.
The type automatically gets filled in, unless that description already
existed (in which case we leave it alone).

If the output units are set to cuft and psi, then we should show the
cylinder size and pressure properly.
NOTE! In the absense of pressure data, we *always* show the cylinder
volume in liter. There's no way to convert it to imperial units, since
the imperial units are not in physical size, but in air volume
normalized to surface pressure..
Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
We used to have the heuristic that if we saw a cylinder working
pressure, then the cylinder size would be in cuft. Which meant that we
couldn't export our working pressures, because it would mess things up
on import.
But working pressure is actually nice to know, if you ever work with
cylinders in imperial units. So now that the import is fixed, add the
working pressure to the export.
Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
That just screws up the good xml files that have everything in
well-defined units and chose the sane metric units.
So do the cuft -> liter conversion only if the input units are
explicitly CUFT, or known ambiguous input (SUUNTO).

This doesn't actually change the cylinder type info in the dive, because
it's too broken for that. Instead it prints out what it would change
things to.
The gtk2 notion of text input focus is *really* odd. Why is the
cylinder type sometimes selected, and sometimes not?

Make it about general equipment management, and start hooking up
functions to show new equipment information when changing dives (and to
flush changes to equipment information for the previously active dive).
Nothing is hooked up yet, and it's now showing just one (really big)
cylinder choice, so this is all broken. But it should make it possible
to at least get somewhere some day.

That seems to be the gtk2 way. Whatever. diveclog ends up defaulting
to metric units, because we all know that's the right thing to do.
However, I learnt to dive in the US, so I'm used to seeing psi and feet.

This turns the depth profile into a generic "plot_info" and calculates

The way cairo does scaling is really really inconvenient, and one of the
things in cairo that is fundamentally mis-designed.
Cairo scaling always affects both coordinates and object sizes, and the
two can apparently never be split apart. Which is very much not what we
want: we want just coordinate scaling.
So we cannot use 'cairo_scale()' to scale our canvas, because that
screws up lines and text size too. And no, you cannot "fix" that by
de-scaling the line size etc - because line size is one-dimensional, so
you can't undo the (different) scaling in X/Y.
Sad. I realize that often you do want to scale object size with
coordinate transformation, but quite often you *don't* want to.
Yeah, we could do random context save/restore in odd places etc, but
that's just a sign of the bad design of cairo scaling.
Work around it by introducing our own graphics context with scaling,
which does it right. I don't like this, but it seems to be better than
the alternatives.
