Some configuration can be set via command line flags with those and further options also being configurable through a file.
By default, Improviz will attempt to load the improviz.yaml file in the same directory it’s run from. This file can be changed by using the
-c <filepath> command line option.
Command line arguments are used to specify the size of the screen with default being 640px wide by 480px high. This can be changed using the
-h command line flags.
stack exec improviz -- -w 1024 -h 768
-- in the above is to make it clear to the stack tool that these arguments are for the improviz executable.
These can also be set by the screenwidth and screenheight keys in the confifg file.
screenwidth: 1024 screenheight: 768
When making Improviz fullscreen, it’s also necessary to pass in the number of the display it should be on.
stack exec improviz -- -f 0
Zero is the primary display. One would be the next attached display to the machine.
This can also be set by the fullscreen key in the confifg file.
The font used by default is arial. An alternative can be used by specifying a path to the true text file in the config file.
font: filepath: /opt/fonts/ComicSans.ttf
The colour of the font and the background can also be set. This is done by giving a list of values corresponding to red, green, blue and alpha. These values should be between 0 and 255. Note a value of 0 for alpha will be fully transparent.
font: foregroundColour: [255, 0, 255, 255] backgroundColour: [0, 0, 0, 0]
Improviz can be given a list of directories to read texture files from. The details of how this works can be found in textures.md
textureDirectories: - /opt/improviz/textures - textures - ./downloads/textures
Improviz can be given a list of directories to read geometry files from. The details of how this works can be found in geometries.md
geometryDirectories: - ./geometries
It is possible to give Improviz a list of code files that it will load on startup. This makes it possible to have specific functions for performances available without having to modify the source or copying it into the editor window each time.
codeFiles: - "./usercode/grid.pz"
Much of the standard library of functions is now implemented like this.
The debug setting can be turned on via the cli or the config file.
stack exec improviz -- -d
