So far Linus has hated all of my attempts to visualize vertical velocity
through color. This time I'm trying something dramatically new: there is
no PURPLE involved. Maybe that will convince him of the value.
We simply calculate the vertical velocity for the current plot segment
(last sample point to this sample point - in this version even without
divisions by zero) and assign a label based on the rate of change. These
labels are translated through a predefined table into colors:
Dark green is +/- 5ft/min (stable)
Light green is descents up to 30ft/min and ascents up to 15ft/min
Yellow is descents up to 60ft/min and ascents up to 30ft/min
Orange is descents up to 100ft/min and ascents up to 60ft/min
Red is outside of those ranges - you are most likely in danger

Even though we go down to an 8pt font the info_frame changes size when the
air info is added. I don't like this but want to see how Linus would like
this resolved before going overboard.
Minor tweaks to the formating (we don't need two decimals when printing
the liters of air consumed).
This patch does NOT remove the plot of the air information in the profile
graph. I think we want to remove that once we like the text where it is,
but I wanted to do one thing at a time.

I suspect the "info" area is better used for actual values, so move the
dive location into the window title instead (using date if no location
info), and title the info frame with date and time.
This just means that the date/time gets removed from inside the frame:
we may want to put air consumption info in there instead?

If the temperature is in a very narrow range the existing code visually
exaggerated the fluctuations. This tries to dampen that effect a bit.

Change the duration max rounding as noted by Dirk, and move the air
consumption down further towards the bottom right corner. In
particular, I make the text positions not scale with the window size,
purely by the size of the text.

Ok, this is pretty much it now. Instead of having various random checks
for "is the time of the sample past the end of the dive" hacks, we not
plot all graphs from the cleaned-up plot_info structure instead of the
raw samples.
Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
Further movement to using the sanitized and cleaned-up plot info rather
than the raw data.
The raw dive data contains samples from the end of the dive that we
don't want to drop, but that we also don't want to actually use for
plotting the dive. So the eventual end goal here is to not ever use the
raw dive samples directly for plotting, but use the diveplot data that
we have analyzed for min/max (properly ignoring final entries) etc.
There's still some data that we take from the samples when plotting, but
it's getting rarer.
Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
Do the min/max calculations only *after* we have removed the extra
surface events at the end.
The Uemis data in particular has a lot of surface events after the dive,
and we don't really want to take them into account since we won't be
plotting them anyway.
Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
.. I'll want to move pressure limit calculations into the 'plot_info',

without having to actually modify the dive data itself (or add new
fields to 'struct dive' just for plotting).

This is the hackiest thing ever, unless you count the previous code that
was even hackier (and just called the gtk main routine at random
places).
The libdivecomputer library is not really set up to be part of the gtk
main loop, and cannot afford (for example) to have lots of mainloop
events while it's parsing. Some dive computers are very timing
sensitive for the communication.
So just start a thread for doing the libdivecomputer stuff, and just
continually call the gtk main loop while that thread is running. I'm
sure we could actually use some gtk signalling thing to make the thread
exit do the right thing, but instead we just poll the status every
100ms.
I did say it was hacky. It does seem to work, though. No more
temporary graying out of the windows when they don't react in a timely
manner because libdivecomputer does some blocking operation.

Sadly, no way to show them yet. But it would be nice to let people
enter them (and it would be doubly nice to have a dive computer that
does it at the surface), and then perhaps just do the "point browser at
google maps" thing.

Crater) from google maps by hand into my divelog.

I never really liked 'diveclog' as a name - it's not like the C part is

Currently we print the temperature every five minutes. Especially with
dive computers that keep rather frequent temperature samples that means
that we have one more interesting data point that we don't label: the
surface temperature at the end of the dive.
This patch adds some logic to try to print the last temperature sample
that was recorded before the dive ended - unless that same value has
already been printed (to avoid silly duplications on dive computers with
less frequent sampling)

This is missing a ton of the information in the .SDA files It only
parses the divelog.SDA file, not the dive.SDA file It ignores the
information on the gas(es) used and all the data on the tanks.
It still draws some strange artefacts at the end of the dive
But it correctly hooks into the import dialogue, it gives you a file
select box (somewhere, I'm sure, a gtk developer cries quietly) and then
parses enough of this file to serve as a proof of concept.

Ok, this is the ugliest f*&$ing printout I have ever seen in my life,
but think of it as a "the concept of printing works" commit, and you'll
be able to hold your lunch down and not gouge out your eyeballs with a
spoon. Maybe.
I'm just doing the cairo display as-is for the printout, which is a
seriously bad idea. I need to not try to do colors etc, and instead of
having white lines on a black background I just need to make thelines be
black on white paper.
But that would involve actually changing the current "plot()" routine,
which is against the point of the exercise right now. This really is
just a demonstration of how to add printing capabilities.

Now we always create the MAX_CYLINDER sets of cylinder widgets. But we
don't actually pack them into the frame - that's a separate phase.
Right now we still do the stupid "always just pack two cylinders" thing,
but the idea is that we can pack just as many as the dive needs on a
per-dive basis.
Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
This just always shows two cylinders, which is obviously bogus, but it's
a good test-case for the multi-cylinder case.
I need to figure out how to dynamically show the right number of
cylinders, but that also involves the notion of adding a cylinder in
order to fill out information that didn't use to exist.
That's lower priority - now the infrastructure seems to be there.

Ok, now we have an array of them, and most of the time we pass the right

cylinders.

So if it's reporting 100% O2, we just ignore it. Sure, it could be

So this actually reports the dive data that libdivecomputer generates.
It doesn't import special events etc, but neither do we for the xml

Instead of writing out the progress events, use them to update a real
progress bar.
Also, we need to handle gtk events while busy with the dive computer
reading. That should *probably* be done with a threading model, because
libdivecomputer does seem to have some timing sensitivity - I'm getting
"failure to read memory block" if I make that loop do the standard
while (gtk_events_pending())
gtk_main_iteration();
thing. Besides, even if we did do that loop, it would still cause
problems when the libdivecomputer code is stuck reading a serial line
that doesn't respond or whatever.
But for now this ugly hack is "good enough" to get further.

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

Ok, so this is quite broken right now: it doesn't actually really *do*

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.
