The project has been renamed to Diffux CI and moved to the Diffux organization github account. diffux_ci version 0.1.0 has the same functionality as likadan v0.0.14, but with a new name for things. The main differences are:

• Instead of running likadan as the command-line tool, you run diffux_ci.
• JS examples are defined on the global diffux object (was previously likadan).
• Configuration is defined in a .diffux_ci.yaml file (previously .likadan.yaml)
• To use a different config file, use the DIFFUX_CI_CONFIG_FILE environment variable (was LIKADAN_CONFIG_FILE)

Changes:

• Add support for the done callback to better support asynchronus examples. https://github.com/trotzig/likadan/commit/7ce9aa006b65baef89d5e835113955cc4bc048f4

Changes:

• Surface js errors that happen during initialization https://github.com/trotzig/likadan/commit/c67feb23acdffa72032ac203fc1889ee137780b9

Changes:

• Give viewports config reasonable defaults (large, medium, small)

Changes:

• Viewport widths are now configured through named viewports in the .likadan.yaml file
• Errors thrown from the likadan runner thread are now propagated to the main thread and printed.
