Configuring code patterns#

Organization admins can manage access to this feature

By default, Codacy analyzes your repositories using a subset of the supported analysis tools and code patterns. These defaults are based on current best practices and community feedback, and you can adapt them to your needs in several ways:

Configuring tools and code patterns using the Codacy UI#

Note

If you update the configurations of a repository that follows a coding standard, Codacy copies the coding standard configurations to the repository and the repository stops following the coding standard. You can then customize the repository configurations without affecting the coding standard.

To configure the tools and code patterns for a repository using the Codacy UI:

  1. Open your repository Code patterns page.

  2. Enable or disable the tools that Codacy will use to analyze the repository.

    Toggling tools

  3. Select a tool to enable or disable its code patterns. To make it easier to find relevant patterns, use the sidebar filters. You can filter by language, issue category, or status.

    To see an explanation of the issues that a pattern detects and how to fix them, click Show details. Some patterns also allow you to configure the rules for detecting issues.

    Tip

    • To enable a group of code patterns, use the filter to select the relevant group of patterns and click Enable all. For example, to enable all Security patterns, click the Security filter and then click Enable all.

    • Codacy displays the tag New for one month next to the name of newly added code patterns.

    Configuring code patterns

  4. Optionally, to take the changes into account immediately, reanalyze the repository manually. Otherwise, Codacy will use the updated configuration when analyzing new commits and pull requests.

Importing pattern configurations from another repository#

Importing tool and code pattern configurations from another repository can help you bootstrap and standardize the tool and code pattern configurations across your repositories.

For example, when adding a new repository on Codacy you can copy the tool and code pattern configurations from an existing repository that's already configured, and then tweak and adapt the settings for your new repository.

Tip

To ensure that multiple repositories consistently follow the same global tool and code pattern configurations, use an organization coding standard instead.

Alternatively, you can also copy the tool and code pattern configurations from one repository to multiple target repositories.

Important

Consider the following when using this feature:

  • Tool matching: Codacy only copies settings for tools that are available on both the source and target repositories, and overwrites the existing settings for these tools on the target repository.
  • Toggle status: Codacy copies the enabled or disabled status of the matching tools from the source to the target repository.
  • Configuration files: Codacy copies the UI configuration of all matching tools, even those set to use configuration files. However, the import doesn't include the configuration mode itself and doesn't copy configuration files across repositories.

The following example illustrates the points above:

Source repository Target repository Target repository after import
Source repository Target repository Target repository after import

To import the tool and code pattern configurations from another repository:

  1. Open your repository Code patterns and click Import patterns.

  2. Follow the instructions to select the source repository and complete the import.

  3. Review and adjust your tool and code pattern configurations if necessary.

Codacy will use the updated configurations on the next analysis.

Using tool configuration files#

Note

After activating a configuration file for a tool, Codacy uses that configuration file even if you exclude it from Codacy analysis using the Codacy UI or a Codacy configuration file.

Codacy supports configuration files for several static analysis tools to help you streamline your setup.

To use a configuration file for a static analysis tool:

  1. Push the configuration file to the root of the default Codacy branch.

  2. Open the repository Code patterns page, select the tool of interest, and select the option Configuration file.

    Note

    • Codacy uses the version of the configuration file in the branch being analyzed. For example, if you open a pull request that includes changes to the configuration file, the analysis results take those changes into account.

    • If Codacy analyzes a branch that doesn't include the configuration file, Codacy reverts to using the code patterns configured for the tool before you selected the option Configuration file on the Code patterns page.

    • For performance reasons, when you update pattern settings using a configuration file, Codacy may display outdated messages for issues identified previously by those patterns.

    Using a configuration file

The table below lists the configuration file names that Codacy detects and supports for each tool:

Tool name Languages Files detected Other info
Ameba Crystal .ameba.yml
Bandit Python bandit.yml, .bandit To solve flagged valid Python "assert" statements, create a bandit.yml on the root of the repository containing: skips: \['B101'\]
Brakeman Ruby config/brakeman.yml
Checkstyle Java checkstyle.xml Supports configuration file in directories other than root and can search up to 5 directories into the repository.
CodeNarc Groovy .codenarcrc
Credo Elixir .credo.exs, config/.credo.exs
CSSLint CSS .csslintrc
dartanalyzer Dart analysis_options.yml Customizing static analysis
detekt Kotlin default-detekt-config.yml, detekt.yml Supports configuration file in directories other than root and can search up to 5 directories into the repository.
ESLint JavaScript, TypeScript .eslintrc.js, .eslintrc.cjs, .eslintrc.yaml, .eslintrc.yml, .eslintrc.json, .eslintrc, .prettierrc, .prettierrc.yaml, .prettierrc.yml, .prettierrc.json, prettier.config.js, .prettierrc.js Plugins configurable on the Codacy UI
Other supported plugins

If you're using module-level ESLint configuration files, you must also include a ESLint configuration file on the root of your repository for Codacy to detect that you're using configuration files. For example, add the following minimal .eslintrc.json configuration file:

{ "root": true }
Hadolint Dockerfile .hadolint.yaml
markdownlint Markdown .markdownlint.json
PHP_CodeSniffer PHP phpcs.xml, phpcs.xml.dist
PHP Mess Detector PHP codesize.xml, phpmd.xml, phpmd.xml.dist

Prospector Python .prospector.yml, .prospector.yaml, prospector.yml, prospector.yaml, .landscape.yml, .landscape.yaml, landscape.yml, landscape.yaml
Pylint Python pylintrc, .pylintrc Plugins
remark-lint Markdown .remarkrc, .remarkrc.json, .remarkrc.yaml, .remarkrc.yml, .remarkrc.js

Stylelint CSS, LESS, SASS .stylelintrc, stylelint.config.js, .stylelintrc.json, .stylelintrc.yaml, .stylelintrc.yml, .stylelintrc.js Supports configuration file in directories other than root and can search up to 5 directories into the repository.
