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, 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, 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 3.0, released in February 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 v3.0.1 (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-3.0.1.tgz Building subsurface under Linux ------------------------------- You need libxml2-devel, libxslt-devel, gtk2-devel, glib-2.0, gconf2-devel, libsoup-devel to build this (and libusb-1.0 if you have libdivecomputer built with it, but then you obviously already have it installed). Check with your Linux distribution how to install these packages. On Debian the package names are different; try libxml2-dev, libgtk2.0-dev, libglib2.0-dev, libgconf2-dev, libsoup2.4-dev, libxslt1-dev, zlib1g-dev. To be able to visualise the dives on a map (optional), using GPS coordinates, install the osm-gps-map-devel (Fedora) or libosmgpsmap-dev (Debian) package. That will be detected and configured at build time. The library is used to embed maps in applications that, when given GPS co-ordinates, draw a GPS track. You also need to have libdivecomputer installed. The current git versions of Subsurface assume that you use libdivecomputer version 0.3, which goes something like this: git clone \ git://libdivecomputer.git.sourceforge.net/gitroot/libdivecomputer/libdivecomputer cd libdivecomputer git checkout release-0.3 autoreconf --install ./configure make sudo make install NOTE! Sometimes you may need to tell the main Subsurface Makefile where you installed libdivecomputer; pkg-config for libdivecomputer doesn't always work unless the project has been installed by the distro. Just edit the makefile directly. Building Subsurface under Windows --------------------------------- Subsurface builds nicely with MinGW - the official builds are done as cross builds under Linux (currently on Fedora 17). A shell script to do that (plus the .nsi file to create the installer with makensis) are included in the packaging/Windows directory. The best way to get libdivecomputer to build appears to be mingw32-configure mingw32-make sudo mingw32-make install Once you have built and installed libdivecomputer you can use sh packaging/Windows/mingw-make.sh to then build subsurface. In order to create an installer simply use sh packaging/Windows/mingw-make.sh create-windows-installer Building subsurface on a Mac ---------------------------- Install MacPorts and install the dependencies from MacPorts: sudo port install gtk2 +quartz py27-pygtk +quartz libusb gtk-osx-application \ automake autoconf libtool libsoup osm-gps-map libzip Install libdivecomputer: git clone git://libdivecomputer.git.sourceforge.net/gitroot/libdivecomputer/libdivecomputer cd libdivecomputer autoreconf --install LIBUSB_CFLAGS=-I/opt/local/include ./configure make sudo make install Install subsurface: git clone git://subsurface.hohndel.org/subsurface.git cd subsurface PKG_CONFIG_PATH="/usr/local/lib/pkgconfig/" make sudo make install-macosx More instructions on how to create a Subsurface DMG can be found in packaging/macosx/README 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 3.0 release they were: Atomics Aquatics Cobalt Cressi / Zeagle / Mares Edy, Nemo Sport N2iTiON3 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.
