This is the README file for the 3.9.2 Beta version of Subsurface. After the release of Subsurface 3.1 we merged the Qt branch into master and started developing the Qt port of Subsurface in the master branch. At this stage the Qt version has reached mostly functional parity with version 3.1. There are some minor items still missing, but in others it far surpasses what was available in 3.1 The developers feel that this version is quite stable and we think we are close to a final release of Subsurface 4.0. There are a small handful of known bugs - please check trac.hohndel.org. Much as we are optimistic about 3.9.2, please do not use this on your "real" dive log files unless you have good backups. Check the XML files after you make changes to make sure that what you saved on disk reasonably resembles what you intended to do. Please check the ReleaseNotes.txt for known issues. And most importantly, please provide us with feedback. Everything below has not been updated since 3.1.1 Subsurface - an Open Source Divelog =================================== Subsurface is an open source divelog program that runs on Windows, Mac and Linux. With Subsurface the user can download dive information directly from a large number of supported dive computers. Subsurface is able to track single- and multi-tank dives using air, Nitrox or TriMix. It displays a dive profile with all related information including air consumption and alarms. It also allows logging of information like weights and exposure protection used, dive masters and dive buddies and enables the user to rate dives and provide additional dive notes. With Subsurface the user can track dive locations including GPS coordinates (which can also be conveniently entered using a map interface). Subsurface calculates a wide variety of statistics of the user's diving and keeps track of information like the user's SAC rate, partial pressures of O2, N2 and He, calculated deco information, and many more. Subsurface allows the user to print out a detailed log book including dive profiles and other relevant information. The program is localized in more than a dozen languages and well supported by an active developer community. One of the major strengths of Subsurface is its support of a wide range of dive computers (most common dive computers are supported with the help of libdivecomputer); a detailed list is at http://subsurface.hohndel.org/documentation/supported-dive-computers). Subsurface can also import existing dive logs from several sources including MacDive, Suunto DM3/DM4, JDiveLog and divelogs.de. Another strength is its ability to visualize the depth profile (and, if available, the tank pressure curve) in very innovative ways that give the user additional information on relative velocity (and momentary air consumption) during the dive through the coloring of the graphs. The latest public version is Subsurface 3.1, released in May of 2013. License: GPLv2 Subsurface can be found at http://subsurface.hohndel.org You can get the sources to the latest development version from the git repository: git clone git://subsurface.hohndel.org/subsurface.git . You can also browse the sources via gitweb at git.hohndel.org If you want the latest release (instead of the bleeding edge development version) you can either get this via git checkout v3.1 (or whatever the last release is) if you have already cloned the git repository as shown above or you can get a tar ball from http://subsurface.hohndel.org/downloads/Subsurface-3.1.tgz Usage: ====== Install and start from the desktop (or you can run it locally from the build directory). ./subsurface You can give a data file as command line argument, or Subsurface picks a default file for you when started from the desktop or without an argument. If you have a dive computer supported by libdivecomputer, you can just select "Download from Divecomputer" from the Log menu, tell it what dive computer you have (and where it is connected if you need to), and hit "OK". The latest list of supported dive computers can be found at http://subsurface.hohndel.org/documentation/supported-dive-computers/ At the time of the 3.1 release they were: Atomics Aquatics Cobalt Cressi / Zeagle / Mares Edy, Nemo Sport N2iTiON3 Leonardo Mares Nemo, Nemo Excel, Nemo Apneist,...

If you want to contribute code, please either send signed-off patches or a pull request with signed-off commits. If you don't sign off on them, we will not accept them. This means adding a line that says "Signed-off-by: Name " at the end of each commit, indicating that you wrote the code and have the right to pass it on as an open source patch. See: http://gerrit.googlecode.com/svn/documentation/2.0/user-signedoffby.html Also, please write good git commit messages. A good commit message looks like this: Header line: explaining the commit in one line Body of commit message is a few lines of text, explaining things in more detail, possibly giving some background about the issue being fixed, etc etc. The body of the commit message can be several paragraphs, and please do proper word-wrap and keep columns shorter than about 74 characters or so. That way "git log" will show things nicely even when it's indented. Reported-by: whoever-reported-it Signed-off-by: Your Name where that header line really should be meaningful, and really should be just one line. That header line is what is shown by tools like gitk and shortlog, and should summarize the change in one readable line of text, independently of the longer explanation. CREDITS: ======== This file was originally started by Linus. The initial instructions for building on a Mac were provided by Henrik Brautaset Aronsen Jef Driessen helped creating the cross-building instructions for Windows A bit of Subsurface history: ---------------------------- In fall of 2011, when a forced lull in kernel development gave him an opportunity to start on a new endeavor, Linus Torvalds decided to tackle his frustration with the lack of decent divelog software on Linux. Subsurface is the result of the work of him and a team of developers since then. It now supports Linux, Windows and MacOS and allows data import from a large number of dive computers and several existing divelog programs. It provides advanced visualization of the key information provided by a modern dive computer and allows the user to track a wide variety of data about their diving.
