Automate label creation on your GitHub projects.

Either specify the labels you want created directly, or read from json-file. Reading from json will ignore all other options and only use what is read from file.

labels labels_or_json --repo "owner/repository" [flags] [options]

In order for labels to be a valid executable, make sure to move labels.py to /usr/local/bin/labels after making it executable. I.e.

sudo chmod +x ./labels.py

sudo cp ./labels.py /usr/local/bin/labels

labels_or_json is either a list of labels you want created, or a file containing json specifying the labels. If you want to read json from file, set the --is_json/-j flag.

--repo/-r specifies the repository in which you wish to create/update labels.

--is_json/-j flags whether or not the labels_or_json is a list of labels or a file specifying the labels. See the example or the GitHub API for the expected json-data.

--update/-u flags whether existing labels should be skipped or updated with new information.

--color/-c specifies the color of the labels. Can either be a hex value or any named color in the CSS4-standard. Defaults to #FFFAFA.

--prefix/-p prefixes each label from the labels_or_json argument.

--suffix/-s suffixes each label from the labels_or_json argument.

--description/-d is the description of each label. In order facilitate dynamic creation of descriptions based on the label name, four special forms can be used: {}, {p}, {s} and {ps}. They resolve to the label name, prefixed label name, suffixed label name and both pre- and suffixed label name, respectively.

--token/-t sets the name of the environment variable which contains the GitHub authorization token. Defaults to MY_GITHUB_TOKEN.

Requires python 3.6+ and requests, click and matplotlib.

labels 0 1 2 3 5 8 --update -r "my/repository" -c "hotpink" -p "f" -d "{} {p} {s} {ps}"

The above will create the labels f0 f1 f2 f3 f5 and f8 in the repository my/repository. If any labels already exist, they will be updated to be equal to the new information. All labels will be colored hotpink and have the description n fn n fn -- where n is the label name -- since f is the prefix, and there is no suffix. Finally, the labels will be created with the authorization token behind the environment variable MY_GITHUB_TOKEN.

If we have the file labels.json:

{
	"labels": [
		{
			"name": "label1",
			"color": "ff0000",
			"description": "a red label"
		},
		{
			"name": "label2",
			"color": "00ff00",
			"description": "a green label"
		},
		{
			"name": "label3",
			"color": "0000ff",
			"description": "a blue label"
		}
	]
}

The command

labels labels.json --is_json -r "my/repository" -t "GITHUB_TOKEN" -p "dont use"

will read the three labels from labels.json and create them in "my/repository" accordingly. The creation is authorized by the token behind the environment variable GITHUB_TOKEN. Since --update is not flagged, if any of the three labels already exist they will be skipped. Finally, since --is_json is flagged the prefix option is ignored.
