# Automation Rules¶

Automation rules allow project maintainers to automate actions on new branches and tags on repositories.

## Creating an automation rule¶

1. Go to your project dashboard

2. Click Admin > Automation Rules

4. Fill in the fields

5. Click Save

## How do they work?¶

When a new tag or branch is pushed to your repository, Read the Docs creates a new version.

All rules are evaluated for this version, in the order they are listed. If the version matches the version type and the pattern in the rule, the specified action is performed on that version.

Note

Versions can match multiple rules, and all matching actions will be performed on the version.

## Predefined matches¶

Automation rules support several predefined version matches:

• Any version: All new versions will match the rule.

• SemVer versions: All new versions that follow semantic versioning will match the rule.

## User defined matches¶

If none of the above predefined matches meet your use case, you can use a Custom match.

The custom match should be a valid Python regular expression. Each new version will be tested against this regular expression.

## Actions¶

When a rule matches a new version, the specified action is performed on that version. Currently, the following actions are available:

• Activate version: Activates and builds the version.

• Hide version: Hides the version. If the version is not active, activates it and builds the version. See .

• Make version public: Sets the version’s privacy level to public. See .

• Make version private: Sets the version’s privacy level to private. See .

• Set version as default: Sets the version as default, i.e. the version of your project that / redirects to. See more in . It also activates and builds the version.

• Delete version: When a branch or tag is deleted from your repository, Read the Docs will delete it only if isn’t active. This action allows you to delete active versions when a branch or tag is deleted from your repository.

Note

The default version isn’t deleted even if it matches a rule. You can use the Set version as default action to change the default version before deleting the current one.

Note

If your versions follow PEP 440, Read the Docs activates and builds the version if it’s greater than the current stable version. The stable version is also automatically updated at the same time. See more in Versioned Documentation.

## Order¶

The order your rules are listed in Admin > Automation Rules matters. Each action will be performed in that order, so first rules have a higher priority.

You can change the order using the up and down arrow buttons.

Note

New rules are added at the end (lower priority).

## Examples¶

### Activate all new tags¶

• Match: Any version

• Version type: Tag

• Action: Activate version

• Custom match: ^1\.\d+$ • Version type: Branch • Action: Activate version ### Delete an active version when a branch is deleted¶ • Match: Any version • Version type: Branch • Action: Delete version ### Set as default new tags that have the -stable or -release suffix¶ • Custom match: -(stable|release)$

• Version type: Tag

• Action: Set version as default

Note

You can also create two rules: one to match -stable and other to match -release.

### Activate all new tags and branches that start with v or V¶

• Custom match: ^[vV]

• Version type: Tag

• Action: Activate version

• Custom match: ^[vV]

• Version type: Branch

• Action: Activate version

### Activate all new tags that don’t contain the -nightly suffix¶

• Custom match: .*(?<!-nightly)\$

• Version type: Tag

• Action: Activate version
