Registration

If you want to test SimpleCore™, SimpleSwitch™ or any of our packages from our SimpleCore™ incubator program, please register here and we will grant you access.

Configure Cog#

To add startup settings to all browsers, edit /apps/browser/homepage.txt. To add startup settings to Cog only, edit /apps/cog/homepage.txt. The Cog configuration file takes precedence over the global browser configuration file.

Multiple settings can be specified as a multiline list, for example

https://www.google.com
--scale=0.1
--bg-color=FF0000

The lines can contain spaces. However, neither use \ separators nor options as –option=’1 2 3’ (it should not happen as most cog options are switches or coma separated lists).

# can be used in an option free line to write license informations or comments.

Settings example :

  • Add https://www.learningcontainer.com/wp-content/uploads/2020/05/sample-ogv-file.ogv to show case video support.

  • Specify the URL

  • Add --scale=FACTOR to set the zoom factor applied to web content

  • Add --doc-viewer to disable Cog’s resource cache (useful for systems with limited RAM)

See Cog command line options for an extended overview of the available settings:

cog -h
cog --help-all
