Constructor Detail
Initiale Augeas::File abstraction, @augeas is needed to perform
augeas operations on it, and the @path is the full path to the
config file.
augeas = Augeas.new(root: "/path/to")
augeas_file = Augeas::File.new(augeas: augeas, path: "/path/to/config-file")Instance Method Detail
Get a settings value from the config file
Let take postgresql as example, consider we have a config file like this data_directory = '/var/lib/postgresql/8.4/main' # use data in another directory
After instantiating the class, get can be used as:
get("data_directory")
# => "/var/lib/postgresql/8.4/main"Return the lens name for this file
When Augeas loads a file, it associates a lens with it, so this method looks up and returns the lens name
Set a settings value on the config file
As Augeas keeps the modifications in memory, don't
forget to call Augeas#save after making changes
set("data_directory", "/path/to/data_directory")
