JSON2Config

A simple utility program which converts openHAB Items from JsonDB Storage files (e.g. org.eclipse.smarthome.core.items.Item.json, org.eclipse.smarthome.core.thing.link.ItemChannelLink.json) to textual configuration files (e.g. my.items).

Usage

You can run the tool with Java:

java -jar json2config-XXX.jar [arguments]

The program has three main features. By default, only the first one will be executed.

1. Converting org.eclipse.smarthome.core.items.Item.json into a *.items file

To convert the JSON file, you can simply put this tool into the JSON DB storage location and run it. This will create a json.items file with all the items from the org.eclipse.smarthome.core.items.Item.json file. Alternatively you can adjust the program arguments to specify the file locations:

  • The -i <path>/--in <path>/--json <path> parameters allow you to specify the input .json file.
  • The -o <path>/--out <path> parameters allow you to specify the output file.
  • The -n parameter allows you to disable this (converting) feature completely; if you want to only append the channel links.

2. Appending channel links from org.eclipse.smarthome.core.thing.link.ItemChannelLink.json to *.items files

To append channel links to already existing .items files, you can use the second feature. If you already have some *.items files in your configuration, it's recommended to also including these files i.e. moving them into the same directory. By default, (when the appending feature is enabled!!) the tool will use channel links from the org.eclipse.smarthome.core.thing.link.ItemChannelLink.json file and append them to all *.items files in the same directory. Alternatively you can adjust the program arguments to specify the file locations:

  • The -c/--channel/--create-channel-links parameters enable the appending feature. Without one of these, this feature won't run!
  • The --channel-file <path>/--channel-link-file <path> parameters allow you to specify the .json file location containing the channel links.
  • The -d <path>/--dir <path>/--directory <path> parameters allow you to specify the directory in which to search for *.items files.

3. Appending metadata from org.eclipse.smarthome.core.items.Metadata.json to *.items files

To append metadata to already existing .items files, you can use the third feature. If you already have some *.items files in your configuration, it's recommended to also including these files i.e. moving them into the same directory. By default, (when the appending feature is enabled!!) the tool will use metadata from the org.eclipse.smarthome.core.items.Metadata.json file and append them to all *.items files in the same directory. Alternatively you can adjust the program arguments to specify the file locations:

  • The -m/--metadata/--append-metadata parameters enable the appending metadata feature. Without one of these, this feature won't run!
  • The --metadata-file <path> parameter allows you to specify the .json file location containing the metadata.
  • The -d <path>/--dir <path>/--directory <path> parameters allow you to specify the directory in which to search for *.items files.

IMPORTANT NOTE: Metadata attributes, found in item files as [ roomHint="Living Room" ] and in the metadata json under the configuration key are not currently supported and will be ignored.

Other program features

When enabling all features, the converting feature will run first, so the appending features can then use the generated .items file to append the channel links.

With the -3/--v3/--openhab3 parameters default values used since openHAB version 3.X are set. Additional parameters that specify a custom file always have priority over these defaults.
