38c79d149d Simplify and clean up dive trip management
This adds a couple of helper functions to manage dive trips
("add_dive_to_trip()" and "remove_dive_from_trip()") and makes those
functions do the trip statistics maintenance (trip beginning times,
number of dives, etc).

This was needed because the dive merge cases for multiple dive
computers showed some rather nasty special cases: especially if the
new dive information has been loaded into an XML file with trips
auto-generated, merging several of these kinds of xml files with
multiple dives in several overlapping trips would completely confuse
our previous code.

In particular, auto-generated trips that had the exact same date as
previous trips (because they were generated from the same dive
computer) really confused the code that used the trip timestamp to
manage the trips.

Adding the helper functions allows us to get the general case right
without having to have each piece of code that handles trip
information having to bother about all the odd rules. It will
eventually also allow us to make the dive trip data structures more
logical: right now the dive trip list is largely designed around the
odd gtk model handling, rather than some more higher-level conceptual
relationship with the actual dives.

But for now, this keeps all the data structures unchanged, and just
modifies them using the new helper functions.

3d8c1e50fc Fix default filename handling errors
The default filename handling is broken in two different ways:

 (a) if we start subsurface with a non-existing file, we warn about
the inability to read that file, and then we exit without setting the
default filename.

This is broken because it means that if the user (perhaps by mistake,
by pressing ^S) now saves the file, he will overwrite the default
filename, even though that was *not* the file we read, and *not* the
file that subsurface was started with.

So just set the default filename even for a failed file open.

The exact same logic is true of a failed parse of an XML file that we
successfully opened. We do *not* want to leave the old default
filename in place just because the XML parsing failed, and possibly
then overwriting some file that was never involved with that failure
in the first place. So just get rid of all the logic to push the
filename saving into the XML parsing layer, it has zero relevance at
that point.

 (b) if we do replace the default filename with a NULL file, we need
to set that even if we cannot do a strdup() on the NULL.

This fixes both errors.

01f1ccff14 Add support for visibility tracking and allow manual entry air temp
Turns out we had a data field for visibility as a length unit - but never
used it. I can never guess how much visibility we actually had on a dive -
but I think most everyone can assign a rating between abysmal (zero stars,
"I couldn't read my dive computer even right in front of my mask" - trust
me, I had some of those dives) to amazing ("five stars, I could see farther
than I though possible" - and I had one or two of those, too). So I
changed this to an integer and am re-using the star infrastructure we have
for the overall dive rating.

When displaying this I was dismayed that we are running out of space in
the "Dive Notes" notbook. So I moved this to the "Dive Info" notebook.
This is not consistent and not logical. I think we need to revisit the
notebooks and think about what we want to display where.

While adding the infrastructure to manually enter the visibility I went
ahead and added the ability to manually enter the air temperature as well
(that was one of the things missing in the previous commit).

Fixes #7

94c98865a7 Improve on the DivingLog importer a bit
This adds a few fields that we parse, but more importantly it also tries
to dynamically decide if the sample temperatures and pressures are in
imperial or metric units.

Dirk suspects that DivingLog generally always does everything in metric,
and the reason why he has crazy sample data in imperial units (both for
pressure and temperature) may be due to a bug in the early Uemis
importer for DivingLog.

Which would actually make a lot more sense than DivingLog really being
so insane on purpose.

Anyway, Dirk's brother Jurgen seems to have everything in metric units,
which would be much saner.  Maybe we should throw away the support for
insane DivingLog files entirely, since it is possible that the only use
ever of the possible source of that bug was Dirk's use of the Uemis
importer.

But for now, we end up just guessing. Current guesses:

 - water temperature is below 32 dgC, so 32+ degrees is in Fahrenheit.

 - tank pressures are below 400 bar, so higher values than that must be
   psi.

99846da77f Conversion to gettext to allow localization
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.

- no testing at all on Windows or Mac
  It builds on Windows :-)

3244a828f3 New XML format for saving dives
This patch makes the trips nest, and it also fixes the fact that you never
saved the trip notes (you could edit it, but saving would throw it away).

I did *not* change the indentation of the dives, so the trip stuff shows
up the the beginning of the line, at the same level as the <dive> and
<dives> thing. I think it's fairly readable xml, though, and we haven't
really had proper "indentation shows nesting" anyway, since the top-level
"<dives>" thing also didn't indent stuff inside of it.

Anyway, the way I wrote it, it still parses your old "INTRIP" stuff etc,
so as far as I know, it should happily read the old-style XML too. At
least it seemed to work with your xml file that already had the old-style
one (I haven't committed my divetrips, exactly because I didn't like the
new format).

It always saves in the new style, though.

c804c4e02e Partial rewrite of the dive trip code
This introduces a new data structure for dive trips - reuseing the struct
dive just got way too messy.

The dive_trip_t datastructure now allows the code to remember if the trip
was auto generated or if its time stamp changed when dives where added to
the trip during auto generation.

The algorithm also distinguishes between dives that were intentionally
added to a trip (either in an XML file or by adding them to trip in the
UI) and dives that were added to trips via autogen. Saving dives that were
added to trips via autogen makes that assignment "intentional".

With this partial rewrite several of the oddities of the old code should
be resolved - especially turning autogen on and off again should get the
divelist back to the previous stage.

Also, when dives are merged during file open or import we now try to pick
the correct tripflag (instead of just ignoring the tripflag completely and
resetting it to TF_NONE by mistake).

Finally, the dive trip debugging code got more verbose and is trying
harder to detect issues at the earliest time possible.

It also implements a portable (and thread-safe) "utc_mkdate()" function

d20428973a Make xml (and CSV) parsing use 'g_ascii_strtod()' rather than 'strtod()'
GTK messes up the standard C library locales by default (instead of just
taking locale information into account internally).  Which breaks
'strtod()' and 'printf()' etc.  Since they screwed that up, they then
added helper functions for undoing that braindamage.  Use it.

I'd like to blame the GTK people, but the standard C libary people bear
*some* responsibility for this.  One of the reasons why people do not
use "setlocale()" in many normal programs is exactly because it messes
up core libc functionality - with number conversion being the main
thing.

Doing things like converting numbers in a locale-specific manner is
something people do want to do, but not *always*.  So the C library
locale code should always had defaulted to C locale, with some *extra*
marker (like a printf/scanf modifier) to say "print/scan in the current
locale".

Because many things absoilutely need to be non-localized.  You don't
want your internal file format to magically change just because you want
to show things to the user in France, for example.

e315abf645 First cut of explicit trip tracking
This code establishes the explicit trip data structures and loads and
saves them in the XML data. No attempts are made to edit / modify the
trips, yet.

Loading XML files without trip data creates the trips based on timing as
before. Saving out the same, unmodified data will create 'trip' entries in
the XML file with a 'number' that reflects the number of dives in that
trip. The trip tag also stores the beginning time of the first dive in the
trip and the location of the trip (which we display in the summary entries
in the UI).

The logic allows for dives that aren't part of a dive trip. All other
dives simply belong to the "previous" dive trip - i.e. the dive trip with
the latest start time that is earlier or equal to the start time of this
dive.

This logic significantly simplifies the tracking of trips compared to
other approaches that I have tried.

The automatic grouping into trips now is an option that defaults to off
(as it makes changes to the XML file - and people who don't want this
feature shouldn't have trips added to their XML files that they then need
to manually remove).

For now you have to select this option, then exit the program and start it
again. Still to do is to trigger the trip generation at run time.

We also need a way to mark dives as not part of trips and to allow options
to combine trips, split trips, edit trip location data, etc.

The code has only had some limited testing when opening multiple files.

The code is known to fail if a location name contains unquoted special
characters like an "'".

This commit also fixes a visual inconsistency in the preferences dialog
where the font selector button didn't have a frame around it that told you
what this option was about.

At the same time, we do want to default to just using the standard

So to allow both testing, and having a nice sane default, just add
support for a SUBSURFACE_XSLT_PATH environment variable that overrides
the default one if it exists.

So then you can just do

9470f713d0 Renumber dives when deleting a dive
... but only do it if the numbering of subsequent dives was consecutive
to begin with.

Note that we do accept unnumbered dives (and will stop the sequence
check if we find one), but in order to renumber dives on delete, we
require that starting with the dive we delete, the subsequent numbered
dives have to be a nice incrementing series.  If that is the case, then
we fix up that numbering as we delete the dive.

Put another way: if the dive numbering was an incrementing sequence
before the delete, then it will be a sane incrementing sequence after it
too.  But if you had missing dives before the delete, we will turn the
delete into just another missing dive.

The basic rule is that we never renumber any dives unless that
renumbering is "obviously correct".  It's better to leave old numbers
as-is (and expect that the user is going to do an explicit re-numbering
operation) than it is to change dive numbers in a sequence that we don't
understand.

I do suspect that we should possibly check the dive number "backwards"
too, but this doesn't do that.

1cbe2444cc Add the ugliest 'delete dive' model ever
This interface works the same way the "edit dive" menu item does: it's a

It kind of works, but it really is a pretty horrible interface.  I'll
need to add a top-level dive menu entry for just deleting all selected
dives instead.  And it would be good to be able to get a drop-down menu
from the divelist instead of having to do it from the dive text entries,
which is just insane.

But that requires gtk work.  I'm not quite ready to get back into that.

time, which means that if you import a dive directly from the dive
computer, it won't have the air sanitization or the proper default
cylinder names.

Of course, most dive computers don't actually save enough cylinder
information for us to do the cylinder name lookup anyway, but some do.
And all Nitrox-capable dive computers do have that O2 percentage that
needs cleanup too.

34dcc119fe parse-xml: read the file into memory separately
Using xmlParseFile() was simple, but I'm planning on extending the file
parsing past just XML, since we want to be able to import other formats
too.  And quite frankly, that means that we'll want to read the file
into memory to look at it before we start parsing it.

We could decide do it by file extensions too, and I'll look at that
approach as well, but regardless of how we do things it's almost
certainly a good idea to do the file access in one place.  The XML
parsing might as well happen from a memory buffer instead anyway.

af290d5eb2 Add typical 0 to 5 star rating for dives
This works ok-ish, but doesn't allow us to click on the stars and edit
them in the divelist, which a user might expect to be able to do - in
most "star rating UIs" you simply click on the n-th star to set that
rating. Here you need to edit the dive and pick the rating from a drop
down menu.

Minor oddity: you can actually (if you force it) write anything you want
into the star rating. But anything that isn't one of the predefined
strings simply results in a zero star rating.

Overall the UI feels a bit... forced. But I think this is quite useful
anyway.

- this requires a change to the SDA file format; thankfully I control that

- once again, the fact that adding samples can change the dive pointer

- there is the issue that we now overload two _different_ uemis formats in

- a minor detail is the problem that the SDA format is kinda odd to parse

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

4f5e3a06ab Parse Uemis cylinder data correctly.
There's a big comment there now about what is going on.  It took me a
while to understand how the crazy seven-tank uemis dive computer
information actually works.

So the Uemis computer has 4 different "tank profiles":
 - single tank air (0)
 - single tank nitrox (1)
 - two-tank nitrox (2)
 - three-tank nitrox (3)
and the computer always lists all seven tank cases (because that's how
you fill them in).

Depending on the "gas.template" you are supposed to then *use* just one
particular profile.  Why the computer doesn't just give you the tanks
for that one profile, who knows? It seems to be more of the same "Uemis
dive data isn't so much about the dive, it's about dive computer state"
mentality.

So we first get the profile information, and then based on that we need
to pick the right tanks from the set of seven that we're presented with.

All clear?

f8de487c2f Make a guess at the cylinder description from the size and pressure
I'll want to also add a way to override/set the cylinder type: both
manually by just setting a size in liters, and by picking from some list
of standard cylinder sizes.

For example, it looks like most of my dives are marked as having
12-liter cylinders.  That is probably some default from Suunto Dive
Manager, or from whatever Dirk did.  It's almost certainly not right for
any of them: as far as I know, the standard cylinders for Lahaina Divers
(which is likely most of the warm water dives) are AL72's for air, and
AL80's for Nitrox.

That would be a 10L and a 11.1L tank respectively, afaik.  I don't know
what a 12-liter tank would be or where that size comes from.

Anyway, the LP85+ tank designation for some of the dives looks more
likely: that's one of the common sizes I've used for local dives.  So
the size of that thing is much more probably correct.

This allows us to use a more compact date format that doesn't need to

value.  So we can use just a two-digit year, and skip the seconds, to
keep the column narrow, while still sorting correctly.

Also, "Depth" is a nice header string, but it is wider than the column
itself, which makes the whole column wider than necessary.  So put the
units in the header instead of in the string, keeping things narrow.

9506c4bf0a Use 'units' value instead of guessing based on integer/FP
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 ;)

d9106995d3 Hack up some very rudimentary support for the Uemis xml format
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.

5001ab66cb Teach the date parser to also parse the international standard date format
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.

99c111e348 Fix up small details in input/output
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.

d5e42d485e gasmix: stop tracking nitrogen percentages
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.

adc7280c02 libdivecomputer does crazy gas mixes too
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.

9741913124 Start parsing gas mixes
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.

da4edbcce8 xml parsing: start traversing properties too
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.
