Commandline Variables

You can provide or override fields of the target using the --vars parameter.

For example, the following is the output of {{}}: fooooooo

And the following is the output of {{}}: ``

Some things to know about these variables:

  • foo is defined in the config file definition for the "everything" target.
  • bar is not defined in the config file.

You should be able to change the output of these variables using a --vars argument containing either inlined JSON or the filename of a JSON file with the variables to apply to the target. For example:

dactyl_build --vars '{"foo": "FOO VALUE", "bar": "BAR VALUE"}'


echo '{"foo": "FOO VALUE", "bar": "BAR VALUE"}' > some_vars.json
dactyl_build --vars some_vars.json
