-c[id_campaign],--campaign[=id_campaign]
goes directly to the campaign with id id_campaign. A selection menu will appear if no id was
specified.
--campaign-difficulty[=difficulty]

--debug-lua
enables some Lua debugging mechanisms
--strict-lua
disallow deprecated Lua API calls
-D,--diffleft-fileright-file
diffs the two WML files; does not preprocess them first (to do that, run them through -p first).
Outputs the diff as DiffWML on standard output or to the file indicated by --output.
-e[file],--editor[=file]
start the in-game map editor directly. If file is specified, equivalent to -l--load.
--fps displays the number of frames per second the game is currently running at in a corner of the
screen as well as writes these values to a file in the userdata directory.
-f,--fullscreen
runs the game in full screen mode.
--gunzipinfile.gz
decompresses a file which should be in gzip format and stores it without the .gz suffix. The
infile.gz will be removed.

compresses a file in gzip format, stores it as infile.gz and removes infile.
-h,--help
displays a summary of command line options to standard output, and exits.
-l,--loadfile
loads the savegame file from the standard save game directory. If the -e or --editor option is
used as well, starts the editor with the map from file open. If it is a directory, the editor will
start with a load map dialog opened there.
-L,--languagelang
uses language lang (symbol) this session. Example: --languageang_GB@latin--log-level=domain1,domain2,...
sets the severity level of the log domains. all can be used to match any log domain. Available
levels: error, warning, info, debug, none. By default the warning level is used for most domains,
but deprecation defaults to none unless combined with the -d option.
--log-precise
shows the timestamps in log output with more precision.
--log-strict
sets the strict level of the logger. Any messages sent to log domains of this level or more severe
will cause the unit test to fail regardless of the victory result. Only relevant when used with
-u.
--logdomains[=filter]
lists defined log domains (only the ones containing filter if used) and exits
--no-log-to-file
prevents redirecting logged output to a file. Log files are created in the logs directory under
the userdata folder.
--log-to-file
log output is written to a file. Cancels the effect of --no-log-to-file whether implicit or
explicit.
--wnoconsole
For Windows, when used with --no-log-to-file, results in output being written to cerr/cout instead
of CONOUT. Otherwise, does nothing.
--max-fpsfps
the number of frames per second the game can show, the value should be between 1 and 1000, the
default is the monitor's refresh rate.
-m,--multiplayer
runs a multiplayer game. There are additional options that can be used together with --multiplayer
as explained below.
--mp-test
load the test mp scenarios.
--new-widgets
there is a new WIP widget toolkit, this option enables it. This is very experimental, don't fill
bug reports since most are known. Parts of the library are deemed stable and will work without
this switch.
--nodelay
runs the game without any delays for graphic benchmarking. This is automatically enabled by
--nogui.
--noaddons
disables loading of user addons.
--nocache
disables caching of game data.
--nogui
runs the game without the GUI. Only available in combination with --multiplayer or --screenshot or
--plugin.
--nobanner
suppress the startup banner.
--nomusic
runs the game without music.
--noreplaycheck
don't try to validate replay of unit test. Only relevant when used with -u.
--nosound
runs the game without sounds and music.
--outputfile
output to the specified file. Applicable to diffing operations.
--passwordpassword
uses password when connecting to a server, ignoring other preferences. Unsafe.
--pluginscript
(experimental) load a script which defines a Wesnoth plugin. Similar to --script, but Lua file
should return a function which will be run as a coroutine and periodically woken up with updates.
-P,--patchbase-filepatch-file
applies a DiffWML patch to a WML file; does not preprocess either of the files. Outputs the
patched WML to standard output or to the file indicated by --output.
-p,--preprocesssource-file/foldertarget-directory
preprocesses a specified file/folder. For each file(s) a plain .cfg file and a processed .cfg file
will be written in specified target directory. If a folder is specified, it will be preprocessed
recursively based on the known preprocessor rules. The common macros from the "data/core/macros"
directory will be preprocessed before the specified resources. Example: -p~/wesnoth/data/campaigns/tutorial~/result. For details regarding the preprocessor visit:
https://wiki.wesnoth.org/PreprocessorRef#Command-line_preprocessor.
--preprocess-defines=DEFINE1,DEFINE2,...
comma separated list of defines to be used by the --preprocess command. If SKIP_CORE is in the
define list the "data/core" directory won't be preprocessed.
--preprocess-input-macrossource-file
used only by the --preprocess command. Specifies a file that contains [preproc_define]s to be
included before preprocessing.
--preprocess-output-macros[=target-file]
used only by the --preprocess command. Will output all preprocessed macros in the target file. If
the file is not specified the output will be file '_MACROS_.cfg' in the target directory of
preprocess's command. The output file can be passed to --preprocess-input-macros. This switch
should be typed before the --preprocess command.
-rXxY,--resolutionXxY
sets the screen resolution. Example: -r800x600.
--render-imageimageoutput
takes a valid wesnoth 'image path string' with image path functions, and outputs to a .png file.
Image path functions are documented at https://wiki.wesnoth.org/ImagePathFunctionWML.
-R,--report
initializes game directories, prints build information suitable for use in bug reports, and exits.
--rng-seednumber
seeds the random number generator with number. Example: --rng-seed0.

Example: --serverserver.wesnoth.org.
--showgui
runs the game with the GUI, overriding any implicit --nogui.
--strict-validation
validation errors are treated as fatal errors.
-t[scenario_id],--test[=scenario_id]
runs the game in a small test scenario. The scenario should be one defined with a [test] WML tag.
The default is test. A demonstration of the [micro_ai] feature can be started with micro_ai_test.
--translations-overpercent
Set the standard for deeming a translation is complete enough to show in the in-game language list
to percent. Valid values are 0 to 100.
-u,--unitscenario-id
runs the specified test scenario as a unit test. Implies --nogui.
--unsafe-scripts
makes the package package available to lua scripts, so that they can load arbitrary packages. Do
not do this with untrusted scripts! This action gives lua the same permissions as the wesnoth
executable.
-S,--use-schemapath
sets the WML schema for use with -V,--validate.
--userconfig-dirname
sets the user configuration directory to name under $HOME or "My Documents\My Games" for windows.
You can also specify an absolute path for the configuration directory outside the $HOME or "My
Documents\My Games". On Windows it is also possible to specify a directory relative to the process
working directory by using path starting with ".\" or "..\". Under X11 this defaults to
$XDG_CONFIG_HOME or $HOME/.config/wesnoth, on other systems to the userdata path.
--userconfig-path
prints the path of the user configuration directory and exits.
--userdata-dirname
sets the userdata directory to name under $HOME or "My Documents\My Games" for windows. You can
also specify an absolute path for the userdata directory outside the $HOME or "My Documents\My
Games". On Windows it is also possible to specify a directory relative to the process working
directory by using path starting with ".\" or "..\".
--userdata-path
prints the path of the userdata directory and exits.
--usernameusername
uses username when connecting to a server, ignoring other preferences.
