2011-09-01Save and parse notes and locationsGravatar Linus Torvalds
It's pretty rough, but it seems to work. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2011-09-01Teach the date parser to also parse the international standard date formatGravatar Linus Torvalds
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>
2011-09-01Fix up small details in input/outputGravatar Linus Torvalds
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.

2011-09-01gasmix: stop tracking nitrogen percentagesGravatar Linus Torvalds
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.

2011-09-01libdivecomputer does crazy gas mixes tooGravatar Linus Torvalds
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.

2011-09-01Start parsing gas mixesGravatar Linus Torvalds
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. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2011-09-01Get rid of our 'ignore' rulesGravatar Linus Torvalds
I'll start doing some kind of "save unparsed things as extended items" thing, and the ignore rules were just there to get rid of some of the noise from early parsing. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2011-09-01xml parsing: start traversing properties tooGravatar Linus Torvalds
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. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2011-09-01Rename some files to be more appropriateGravatar Linus Torvalds
The executable is now called 'divelog'. If this gets useful enough to actually *use*, I guess I'll have to come up with a real name some day. Add a silly README, rename 'parse' to 'parse-xml'. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
