DESCRIPTION
Spring is a versatile 3D RTS game engine. Using extensively Lua for scripting game-specific code to make
nearly every aspect of the engine customizable, from GUI, to unit AI, to pathfinding.
It is mainly designed around online multiplayer games but can also be played in single-player mode
against AIs.
This engine version runs graphics and simulation in a single thread, and may marginally increase the
performance on single-core systems.

--list-config-vars
Dump all default config vars in JSON-format to STDOUT
-g, --game::'GAME'
instantly start the GAME with a minimal setup. Requires --map to be present, too. Sets the modoption
minimalsetup = 1
-m, --map::'MAP'
Requires --game to be set, too. see --game
FILES
~/.config/spring/
The default data-directory (see section DATA DIR).
~/.config/spring/springsettings.cfg
Contains the users settings for the engine, for things like graphic and sound.
/etc/spring/datadir
Contains the : separated paths to additional data-dirs (see section DATA DIR).
ENVIROMENT VARIABLES
SPRING_LOG_SECTIONS Selective functionality to change the verbosity (separated by ,).
SPRING_WRITEDIR Define custom primary write DATA DIR. Place where spring saves logs, settings, ...
SPRING_DATADIR Adds additional DATA DIRs Spring will search for files (separated by :).
SPRING_ISOLATED If defined, Spring will stop searching files outside of the binaries directory. If it is
set to a valid directory path, it will be used as the isolation directory. See the --isolation and the
--isolation-dir options.
SPRING_NOCOLOR Same as spring --nocolor.
PORTABLE MODE
An all-in-one-folder setup, which allows to run Spring without installation. To do so all relevant files
(binaries & basecontent) must be in a single folder, esp. spring(.exe), libunitsync.so/unitsync.dll and
springsettings.cfg. Spring will then use the all-in-one-folder for writing and won’t do so anywhere else
on the system, but it may open other files & directories for reading.
ISOLATION MODE
Not to confuse with Portable Mode, this mode disables all automatic Data Dir scanning and limit reading &
writing to a single folder. This is very usefull when games want to run separate from other Spring games.
DATA DIRS
Data directories are searched for content, and among other things, may contain:
• config files
• logs
• games
• maps
• AIs
• cache
Sorted by priority the engine may use multiple data directories, but it will use only the one with the
highest priority as writable, to write cache & log files to. The hierarchy the engine loads DATA DIRs in
can be grouped in 3 sections:
┌──────────┬───────────────────┬───────────────────┬───────────────────┬───────────────────┐
│ priority │ section │ normal │ portable │ isolation │
├──────────┼───────────────────┼───────────────────┼───────────────────┼───────────────────┤
│ │ │ │ │ │
│ high │ custom user write │ -e directory │ -e directory │ -e directory │
│ │ │ defined via │ defined via │ defined via │

└──────────┴───────────────────┴───────────────────┴───────────────────┴───────────────────┘
CONFIG_HOME
Config directories in user’s home.
*nix/MacOSX:
${XDG_CONFIG_HOME-"~/.config"}/spring
~/.spring
Windows:
C:/.../My Documents/My Games/Spring/
C:/.../My Documents/Spring/
C:/.../All Users/Applications/Spring/
INSTALL_DIR Location of spring-legacy binary.
ETC_DIRS Additional : separated DATA DIRs defined in /etc/spring/datadir.
USR_SHARE
*nix/MacOSX: /usr/.../share/spring & binary dir if is Data Dir
MacOSX: .../Spring.app/Contents/Resources/share/games/spring/base/
Windows: Install directory
ISOLATION_DIR
Mode A (--isolation): INSTALL_DIR
Mode B (--isolation-dir): supplied dir
CONFIG FILES
Spring can load configurations from multiple files and merge them. So similar to DATA DIRs there is one
file where the engine writes to and multiple read-only files.
It scans following directories for config files :
┌───────────┬────────────────────────────────────────────────┐
│ priority │ scanned directories │
├───────────┼────────────────────────────────────────────────┤
│ │ │
│ exclusive │ file defined via --config (when │
│ │ defined only this is loaded) │
├───────────┼────────────────────────────────────────────────┤
│ │ │
│ high │ write DATA DIR │
├───────────┼────────────────────────────────────────────────┤
│ │ │
│ │ -e (skipped in Isolated mode) │
│ │ │
│ │ *nix/MacOSX: ~/.springrc │
│ │ │
│ │ Windows: │
│ │ C:\Users\USER\AppData\Local\springsettings.cfg │
├───────────┼────────────────────────────────────────────────┤
│ │ │
│ low │ all read DATA DIRs │
└───────────┴────────────────────────────────────────────────┘
(The one with highest priority will be used for writing.)
The filename of such config files can be as following:
┌──────────┬─────────────────────────────────────┐
│ priority │ filenames │
├──────────┼─────────────────────────────────────┤
│ │ │
│ high │ springsettings-%Engine_Version%.cfg │
├──────────┼─────────────────────────────────────┤
│ │ │
│ │ springsettings.cfg │
├──────────┼─────────────────────────────────────┤
│ │ │
│ │ springrc-%Engine_Version% │
│ │ (*nix/MacOSX only) │
├──────────┼─────────────────────────────────────┤
│ │ │
│ low │ springrc (*nix/MacOSX only) │
└──────────┴─────────────────────────────────────┘
(An example for a versioned config file is "springsettings-94.1.cfg".)
