Action Size

Determine a label to be added based on the number of lines changed in a pull request.

Counts the number of lines changed in a pull request. And buckets this number into a few size classes (S, L, XL, etc).

It would be better to work with other actions which add and remove labels. See the example below for detail.

This action is inspired by Kubernetes Prow's size plugin.

Note

GitHub API implicitly creates a label when it will add the label to an issue or a pull request but the label doesn't exists. The label has the default color and no description.

If you don't prefer the default label, it's better to create labels indicating a pull request size.

Inputs

All the inputs are optional.

Size labels

The inputs size_${size}_label indicates what name each label has.

NAME	DESCRIPTION	TYPE	REQUIRED	DEFAULT
size_xs_label	The name for size XS label.	string	false	size/XS
size_s_label	The name for size S label.	string	false	size/S
size_m_label	The name for size M label.	string	false	size/M
size_l_label	The name for size L label.	string	false	size/L
size_xl_label	The name for size XL label.	string	false	size/XL
size_xxl_label	The name for size XXL label.	string	false	size/XXL

Size thresholds

The inputs size_${size}_threshold indicates how many lines changed is corresponding to each label. Must be a minimal number, rather than a range.

NAME	DESCRIPTION	TYPE	REQUIRED	DEFAULT
size_s_threshold	The threshold for size S.	number	false	10
size_m_threshold	The threshold for size M.	number	false	30
size_l_threshold	The threshold for size L.	number	false	100
size_xl_threshold	The threshold for size XL.	number	false	500
size_xxl_threshold	The threshold for size XXL.	number	false	1000

Outputs

NAME	DESCRIPTION	TYPE
new_label	The new label's name to be added. If there's no label to be added, it the value is ''.	string
stale_labels	The stale labels' name to be removed. If there're multiple labels, they're separated by line breaks. If there's no labels to be removed, it the value is ''.	string

Example

This action works well with actions-ecosystem/action-add-labels and actions-ecosystem/action-remove-labels.
