Adjust the color for pN2 to the standard for this gas (black). We keep pO2
green (even though the ISO 32 color for that would be white). pHe is

Not sure this is the best naming scheme (General Settings / Tec Settings)
but it's a start.
The idea is to have the settings that a recreational diver might care
about on the first page, and all the other stuff on the second one. Let's
see how this works out long term. For now I moved OTU over and added
toggles for the different partial pressure graphs (only the pO2 one is
implemented so far).
Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
So far this is done unconditionally. This already starts some of the
infrastructure for other gases, but so far only O2 is handled.
We also need a pressure scale on the right to make this useful - or we
need to do peek / trough pressure prints like we do for temperature and
depth.
Finally, I think I want to move the plot further down, maybe make the
whole plot area taller if we are plotting partial gas pressures as well.

Here is what Linus reported:
I think you have made a mistake in trying to translate some of
libdivecomputer.c
Translating some of those things based on locale is *wrong*, because
they are saved in the XML file.
That covers at least the warnings: they'll get translated when you
import them, and then saved to the XML file as that translation, but
now if you start subsurface in another locale, they will not get
translated back.
So translating XML file contents is fundamentally buggy. It just
shouldn't be done.
So all the "translations" for the event handling are buggy, and
generate crap. Please don't do that. Leave them as English.
And of course he is absolutely right. However, instead of not translating
them at all, this commit fixes things a better way - we now mark the
strings for translation but store the original English strings everywhere
(in the in-memory data structure as well as in the XML file). Only when we
actually display something on the screen (in a tooltip or in the filter
dialog) do we actually translate the strings into the native language.
This should address both Linus' issue and the desire to have localized
event texts.

This is just the first step - convert the string literals, try to catch
all the places where this isn't possible and the program needs to convert
string constants at runtime (those are the N_ macros).
Add a very rough first German localization so I can at least test what I
have done. Seriously, I have never used a localized OS, so I am certain
that I have many of the 'standard' translations wrong. Someone please take
over :-)
Major issues with this:
- right now it hardcodes the search path for the message catalog to be
./locale - that's of course bogus, but it works well while doing initial
testing. Once the tooling support is there we just should use the OS
default.
- even though de_DE defaults to ISO-8859-15 (or ISO-8859-1 - the internets
can't seem to agree) I went with UTF-8 as that is what Gtk appears to
want to use internally. ISO-8859-15 encoded .mo files create funny
looking artefacts instead of Umlaute.
- no support at all in the Makefile - I was hoping someone with more
experience in how to best set this up would contribute a good set of
Makefile rules - likely this will help fix the first issue in that it
will also install the .mo file(s) in the correct place(s)
For now simply run
msgfmt -c -o subsurface.mo deutsch.po
to create the subsurface.mo file and then move it to
./locale/de_DE.UTF-8/LC_MESSAGES/subsurface.mo
If you make changes to the sources and need to add new strings to be
translated, this is what seems to work (again, should be tooled through
the Makefile):
xgettext -o subsurface-new.pot -s -k_ -kN_ --add-comments="++GETTEXT" *.c
msgmerge -s -U po/deutsch.po subsurface-new.pot
If you do this PLEASE do one commit that just has the new msgid as
changes in line numbers create a TON of diff-noise. Do changes to
translations in a SEPARATE commit.

Tests have shown that the most multi-platform way to do printing with GTK is
to use GTK_UNIT_INCH (or GTK_UNIT_MM) with GtkPrintOperation. Tested on
Linux, OSX, Windows.
However this requires the appropriate scaling for Pango and Cairo to be done,
with separate plotting logic for printing and drawing on the screen. To achieve
that, profile.c:plot() now accepts a scaling parameter from type
"scale_mode_t" defined in "display.h".
Also due to new scale, small decimal numbers (such as 6.12345) cannot be well
stored in "cairo_rectangle_int_t" therefore it is replaced with
"cairo_rectangle_t", which uses doubles to provide Cairo with a drawing
area.

This completely changes how we keep track of selected dives: instead of
having an array listing the selection ("selectiontracker") or trusting
the gtk selection information, just save the information about whether a
dive is selected in the dive itself.
That makes it trivial to keep track of the state of selection across
group collapse/expand events, or when changing the tree view model. It
also ends up simplifying the code and logic in other ways.
HOWEVER, it does currently (re-)introduce an annoying oddity with gtk:
if you collapse a dive trip that has individual selections, gtk will
forget those selections ("out of sight, out of mind"), and when you do
*new* selections, the old hidden ones remain.
So there's some games required to make gtk do sane things. We may need
to either explicitly drop selections when collapsing trips, or make sure
the group entry gets selected when collapsing a group that has
selections in it. Or something.
There may be other issues introduced by this too.

This calculates a mean depth for the dive with a fixed ascent/descent
rate and an assumption that all of the bottom time is at the maximum
depth. It's not much, but it allows some derived values such as SAC to
make more sense.

assumptions instead of putting the samples at fixed percentages of the
dive duration.

We do all the pressures in mbar, which has plenty of precision for
interpolated pressures - even when we then do our discrete integration
over many samples.
However, when we calculate those interpolated pressure points, we should
make sure that we round the result correctly, otherwise the consistent
rounding errors (from truncating the FP value into our integer mbar
values) will result in a final pressure that is noticeably off in ugly
ways (ie "end pressure set by hand to 750 mbar, but shown as 748").
Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
This reverts commit abdee5b1b8.
There's no point in doing random hacks. Instead, do the intermediate
pressure calculations with proper rounding instead of always truncating
to mbar. With the math done correctly we have enough precision that the
end result of the pressure interpolation doesn't have the kind of errors
that caused Dirk to try to fix things up later.

While printing the last pressure in the calculated sequence may seem more

Some parts of the existing code used the depth at the time of the sample
to calculate the sac rate - it makes much more sense to use the average
depth. But that requires us to loop over the entries and average the
individual sac rates per segment instead of just using the beginning and
end depth of the multi-segment interval we use for smoothing purposes.
This may seem like a subtle detail, but it does in fact matter when we
plot the synthetic tank pressure values that we create when we have no
tank pressure data in the samples.
Another detail we change here is to not artificially start with a forward
looking segment of the full SAC_WINDOW but instead just start with the
first two data points and then simply let the time window grow until it
hits SAC_WINDOW - at which point it becomes a sliding window.
Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
This changes the algorithm that picks the sac color to consider
+/- 1 l/min to be the same color (before the color changed every
time you crossed above or below the average which looked silly with
our synthetic "constant sac" values as those are discrete and oscilate
around the average.
This also changes the order in which things are drawn so so that the
pressure plot goes over the depth profile plot (so the red shading of the
dive no longer changes the color of the tank pressure plot).

Linus suggested that instead of using absolute SAC values to base the
color on (which forced us to pre-define which SAC rates are green and
which are red) we should color the tank pressure plot relative to the avg
SAC rate of that dive - which I think makes the coloring much more useful
to spot when on your dive you were doing well and when you were not.
Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
Similar to color indicating vertical speed in the profile plot we now use
color in the tank pressure plot to indicate current SAC rate.
We use a 45 sec sliding window to make sure we cover at least two breaths
for each current SAC sample to avoid artificial oscillation based on
breathing rhythm for corputers with high sample resolution.
Not sure about the color coding that I'm using right now - it's green-ish
for SAC rates under 15l/min ~= .55cuft/min and turns yellow and red as you
go higher. That seems to work well for me, but for other divers this may
be way off (or at least not as useful). Maybe this should be configurable?
This is a lot more diver specific than the vertical velocity where there
are clear recommendations based on safety considerations on what is good
and bad.
As a side effect, this removes the color coding that showed you whether
you were looking at pressure data from samples (green) vs. interpolated
pressure data (yellow). Not sure if people really want to see that. We
might be able to indicate this differently (I am thinking different line
width or transparency or something along those line)
