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 as follows:

Configuring tools and code patterns using the Codacy UI#

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

  1. Open your repository Code patterns page.

    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 filters above the pattern list. You can filter by issue category, status, severity level, or display only recommended code patterns.

    To see an explanation of the issues that a pattern detects and how to fix them, click the respective dropdown arrow.

    Tip

    • To enable a group of code patterns, use the filter to select the relevant group of patterns and click the checkbox in the header of the patterns list.

    • 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.

Discover code patterns across all tools#

To discover code patterns across all tools, click Discover patterns at the top of the Tools list.

Use the input field to search for patterns by name or description. You can also filter by severity level, issue category, recommended or disabled patterns.

You can also expand your search to include patterns from all tools, even if the tool is not enabled for the repository.

Customizing applied coding standards#

To apply or edit a repository's coding standards, click Customize in the Following ... section at the top of the Code patterns page.

Customize applied coding standards

Select the coding standards that you want to follow or stop following and click Apply.

Customize applied coding standards

Customizing patterns when following coding standards#

Tools and patterns enabled by a coding standard are enforced and cannot be disabled. You can add extra tools and patterns, if these are not enabled by any applied coding standard.

Using tool configuration files#

Note

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 activate the toggle to use a 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.yaml, .bandit, bandit.toml, bandit.ini 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
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 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
PMD Apex, Java, JavaScript, JSP, PL/SQL, XML, Velocity and Visualforce ruleset.xml, apex-ruleset.xml Supports configuration file in directories other than root and can search up to 5 directories into the repository.
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
Revive Go revive.toml
RuboCop Ruby .rubocop.yml, .rubocop-codacy.yml Supports alternative configuration file .rubocop-codacy.yml for Codacy analysis, allowing exclusion of private gems. This prevents analysis issues caused by private gem references, ensuring proper validation by Codacy.
Scalastyle Scala scalastyle-config.xml, scalastyle_config.xml
Semgrep Apex, C++, C#, Dockerfile, Elixir, GitHub Actions, Go, Java, JavaScript, Kotlin, PHP, Python, Ruby, Rust, Scala, Shell, Swift, Terraform, TypeScript .semgrep.yaml
SonarC# C# SonarLint.xml
SonarVB Visual Basic SonarLint.xml
Spectral AsyncAPI, OpenAPI .spectral.yaml, .spectral.yml, .spectral.json
SpotBugs Java, Scala findbugs.xml, findbugs-includes.xml, findbugs-excludes.xml, spotbugs.xml, spotbugs-includes.xml, spotbugs-excludes.xml Supports configuration file in directories other than root and can search up to 5 directories into the repository.
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.
SwiftLint Swift .swiftlint.yml
TSQLLint Transact-SQL .tsqllintrc
