So we don't want to save working pressure, but cylinder type knowledge
would be lovely and useful. And we can probably make a good initial
guess, or at least let people fill it in later.

It was a mistake to save it - and I did it just because other dive
managers did. It's a totally nonsensical measure, and nobody cares.
The only thing that matters is the size of the cylinder, and the
*actual* pressures. Those give actual air consumption numbers, and are
meaningful and unambiguous.
So the "working pressure" for a cylinder is pointless except for two
things:
- if you don't know the actual physical size, you need the "working
pressure" along with the air size (eg "85 cuft") in order to compute
the physical size. So we do use the working pressure on *input* from
systems that report cylinder sizes that way.
- People may well want to know what kind of cylinder they were diving,
and again, you can make a good guess about this from the working
pressure. So saving information like "HP100+" for the cylinder would
be a good thing.
But notice how in neither case do we actually want to save the working
pressure itself. And in fact saving it actually makes the output format
ambiguous: if we give both size and working pressure, what does 'size'
mean? Is it physical size in liters, or air size in cu ft?
So saving working pressure is just wrong. Get rid of it.
I'm going to add some kind of "cylinder description" thing, which we can
save instead (and perhaps guess standard cylinders from input like the
working pressure from dive logs that don't do this sanely - which is all
of them, as far as I can tell).

I'm aiming to really differentiate in dive log software by making my XML
export files be *clean*, dammit.
That means that we don't have random names, we don't have crazy random
units, and we don't have redundant information.
So when the temperature doesn't change, just don't report it. That's
already what "no sample" means, just clean things up.

Word wrap the info textview. Also do not show the scrollbars if not necessary.
Change location to a text entry instead of text view.
It's not called 'parse' any more. And I think I should rename 'divelog'
too to something more unique. Right now the working name for the
project is 'diveclog' (kind of like 'jdivelog') , but I'm not convinced
that the "C implementation" part is really important enough to make a

"subsurface"? I don't know. Maybe I should follow the "name all

It never actually triggered anything for me, but any buffered data might
be lost, especially if you force-exit the application after saving a
dive log.
This probably explains a corrupted (truncated) dive file report from

I didn't even notice that the "File" part of the file menu no longer
showed up, since the keyboard accelerator for ^S worked fine.. But
apparently there's no default label associated with GTK_STOCK_FILE in
gtk2, so the "File" text went away with the conversion to GtkUIManager
in commit 4d62478e14 ("Use the newer GtkUIManager for menu creation.")
The addition of a Quit menu entry with the associated keyboard
accelerator also makes ^Q "just work".
Of course, if we actually tracked dirty state etc, we could perhaps ask
the user whether they wanted to save or something. But I'm not exactly
famous for my GUI chops, so ..

It's all calculated anyway, and for the same reason we don't bother even
parsing it at load time, we really shouldn't bother saving it either.
The only thing you can do with that value is "check if the percentages
add up to 100%", and so what?

If given multiple dives at the same time, just de-dup the dives. This
happens when you've dumped the whole dive-computer several times, and
some dives show up in multiple dumps.
When de-duping, try to avoid dropping data. So if one dive has notes
attached to it, and the other one does not, pick the notes from the dive
that does have them. Obvious stuff like that.
The sample merge is also written so that it should be possible to merge
two dives. Which we don't actually do yet.

It looks like the "units.pressure" setting is only about the units that
things are *shown* in on the wrist computer: the units in the file are
always in bar (or rather, centi-bar).
Which is definitely the right thing to do, and means that we shouldn't
care about parsing the units setting. It's purely about how something
is shown, not about parsing.
That's probably true of the other units too, but let's see when I have
more data to go on.
Also, parse water temperatures and tank pressure.
Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
We still end up guessing based on magnitude of the value, though: it
might be 'bar' or 'mbar', we end up picking one or the other based on
just how big the value is.
I should make it look at any possible explicit units too, since at least
with good xml, they exist. Of course, the only good xml I've seen so
far is the one we generate ourselves ;)

I think I'll need to re-organize the handling of per-format code, but
for now we just mix it all up.
The uemis conversion is also questionable even for just the small parts
I do. Does it really do "centiPSI"? That sounds crazy. I'm waiting for
Dirk to send me some actual human-readable output from the dives, right
now some of it is just rough guesses.

Use the "empty element" form for samples that don't have any events
associated with them (and none do, right now). This avoids that
annoying "</sample>" crud.
And output the units in the output helpers, so that you can't forget
them even if you try.

When we see a number like 23.145, we'd better always also see a unit.
It's just good practice. So add 'min' to duration (and use only two
digits for number of seconds), and 'm' to depth.
And write the date in international standard format.
Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
The standard way to write a date is yyyy-mm-dd, which is unambiguous and
sorts correctly.
We parsed that right in the 'datetime' case, but not in the normal date
case. And we do want to use that in our output format, exactly because
it's standard.
And also parse 'duration' for the dive duration. It's what we use when
saving, it just so happened that we ended up not parsing it right, but
then picking it up from the samples instead.
Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
Be more careful with FP conversions, and with the Kelvin<->C offset.
And make sure to use the same names when saving as when parsing.
Now when we save a set of dives, then re-load them, and save again, the
second save image is identical to the first one.
Of course, we don't actually save everything we load, so we still do
lose information when we load and then save the result. But at least we
now don't lose the information that we *do* save.

This just generates another xml file. Don't get me wrong: I still don't
like xml, but this way we can save in the same format we load things
from. Except the save-format is a *lot* cleaner than the abortion that
is Suunto or libdivecomputer xml.
Don't bother with some crazy xml library crap for saving. Just do it!

The only thing you can do with that thing is screw things up (like
libdivecomputer did). There's no value in tracking the "filler" gas,
since you can always just calculate it from the gases that actually
matter.
So just track Oxygen and Helium - and make sure they have sane values.

Did I just say "In comparison, the libdivecomputer output is nice and
sane"?
It turns out that libdivecomputer has been doing some drugs too when it
comes to gas mixes. Like showing O2 percentages as 255.0% and N2
percentages as -155.0%.
Clearly libdivecomputer uses a 'unsigned char' for oxygen percentage,
and makes "-1" be "undefined". And then it prints that non-existing mix
out, and in the process does MATH on the damn thing ("100-O2") to
"calculate" the nitrogen percentage.
Christ.
Just make the parser silently ignore the craziness, because printing out
"Strange percentage reading -155.0" a few hundred times just doesn't
make anything any better.

The suunto xml is just completely crazy. What's the helium percentage
companion to "o2pct"? Would it be "hepct"? No. It's "hepct_0".
Ok, so they didn't number the first o2pct, which could be seen as sane:
that's the only mix value that should always exist. And they clearly
started their indexing with 0. So with multiple mixes, you'd then
expect "o2pct_1" and "hepct_1", right?
Wrong! Because XML people are crazy, the second O2 mix percentage is
obviously "o2pct_2". So the O2 percentages are one-based, with an
implicit one. But the He percentages are zero-based with an explicit
zero. So the second mix is "o2pct_2" and "hepct_1".
I'd like to ask what drugs Suunto people are on, but hey, it's a Finnish
company. No need to ask. Vodka explains everything. LOTS AND LOTS OF
VODKA.
In comparison, the libdivecomputer output is nice and sane, and uses a
'gasmix' node. Of course, now we have so many different XML nesting
nodes to check that I just made it an array of different noces. That
also allows me to mark the suunto case, so that we only do the "check
for crazy alcoholic xml entries" when it's a suunto file.
The "type of file" thing is probably a good idea for deciding on default
units too. Some day.

This requires us to change the way we match things up, because now we
can have things like
dives.dive.sample.event.time
and
dives.dive.sample.time
and they are different things (that "sample.event.time" is a 'time'
property of the 'event').
Now, this is always going to be ambiguous, since our linearized name of
the xml doesn't really care whether it's a xml node "child" or a
"property", but quite frankly, I don't care. XML just isn't worth the pain.
In fact, maybe this ambiguity can end up being a good thing. We will
parse these two different lines of XML the same way:
<dive><sample><time>50</time><depth>10.8</depth></sample></dive>
<dive><sample time="50" depth="10.8"></sample></dive>
and the attribute approach seems to be the nicer one. Maybe I'll use
that for the output format.
