Autolabels

Auto labels will automatically apply labels to issues and PRs based on the [autolabel] configuration in triagebot.toml.

Triggered by labels

Labels can be added when another label is added. The trigger_labels config option specifies which labels will cause this to trigger.

# Automatically applies the `I-prioritize` label whenever one of the labels
# listed below is added to an issue (unless the issue already has one of the
# labels listed in `exclude_labels`).
[autolabel."I-prioritize"]
trigger_labels = [
    "regression-untriaged",
    "regression-from-stable-to-stable",
    "regression-from-stable-to-beta",
    "regression-from-stable-to-nightly",
    "I-unsound",
]
exclude_labels = [
    "P-*",
    "T-infra",
    "T-release",
    "requires-nightly",
]

Exclude labels support shell-like * glob patterns.

Triggered by files

Labels can be added based on which files are modified in a PR. The trigger_files config option specifies which files will cause the label to be added. Paths are matched with starts_with.

# Adds the `T-compiler` label to any PR that touches `compiler` or
# `src/test/ui` unless it already has a `T-*` label.
[autolabel."T-compiler"]
trigger_files = [
    "compiler",
    "src/test/ui",
]
exclude_labels = [
    "T-*",
]

Triggered by new PRs

Labels can be added to any PR when it is opened. Set the new_pr = true config option to enable this. For example:

[autolabel."S-waiting-on-review"]
new_pr = true
