Mentions

Triagebot can leave a comment on PRs that touch certain files. This can be useful to alert people who want to review any change to those files, or to provide a informational message to the author.

Usage

Mentions are triggered automatically when a PR is opened (or new changes are pushed) based on the configuration in triagebot.toml of the repo.

Configuration

To enable mentions, add entries to the [mentions] table in triagebot.toml. Each key in the table should either be a path in the repo or should be a string (when type="content").

Triagebot will check for modifications:

• to any file that starts with the given path when type="filename" (the default)
• or to any added lines of the PR when type="content"

For example, library/std would match anything under the library/std directory like library/std/src/process.rs.

There are two optional values that can be specified in the table:

• type — Specifies the matching type that must be satisfied, either filename (the default) or content.
• cc — A list of strings of users to ping. They should start with @ like @ehuss or @rust-lang/clippy. If this is not specified, nobody will be pinged.
• message — This is the message that will be included in the comment. If this is not specified, the comment will say Some changes occurred in {path}.

Example:

[mentions."src/tools/cargo"]
cc = ["@ehuss"]

[mentions."src/rustdoc-json-types"]
message = """
rustdoc-json-types is a **public** (although nightly-only) API.
If possible, consider changing `src/librustdoc/json/conversions.rs`;
otherwise, make sure you bump the `FORMAT_VERSION` constant.
"""

[mentions."#[rustc_attr]"]
type = "content"
cc = ["@someone"]
