Codacy configuration file

Codacy supports configuring certain advanced features through a configuration file:

  • Ignoring files globally, for duplication, or a specific tool

  • Configuring a specific repository directory on which to start the analysis

  • Adding custom extensions to languages, keeping in mind that some tools might not work out of the box with those extensions

Note

  • If a Codacy configuration file exists in your repository, the Ignored Files settings in the Codacy UI don't apply.
  • To disable a tool you must use the Code Patterns page instead.

To use a Codacy configuration file:

  1. Create a text file with the name .codacy.yml or .codacy.yaml on the root of your repository.

  2. Add your settings to the configuration file based on the example template below.

    Important

    The configuration file must start with a line containing a triple dash (---).

    ---
    engines:
      rubocop:
        exclude_paths:
          - "config/test.yml"
        base_sub_dir: "test/baseDir"
      duplication:
        exclude_paths:
          - "config/test.yml"
        config:
          languages:
            - "ruby"
    languages:
      css:
        extensions:
          - "-css.resource"
    exclude_paths:
      - ".bundle/**"
      - "spec/**/*"
      - "benchmarks/**/*"
      - "**.min.js"
      - "**/tests/**"
    
  3. Optionally, validate the syntax of your configuration file with the Codacy Analysis CLI by running the following command in the same folder as the Codacy configuration file:

    codacy-analysis-cli validate-configuration --directory `pwd`
    

Syntax for excluding files

To ignore files, you must use the Java glob syntax to define one or more exclude_paths patterns. For example:

Example pattern Ignored files
test/README.md The file test/README.md
test/* All files in the root of test
test/** All files and directories inside test
test/**/* All files inside sub-directories of test
**.resource All .resource files across all your repository
**/*.resource All .resource files in all directories and sub-directories

Which tools can be configured and which name should I use?

You can configure all tools supported by Codacy using the configuration file.

The following are the tool names that must be used in the Codacy configuration file:

ameba
bandit
brakeman
bundleraudit
checkstyle
codacy-scalameta-pro
codenarc
coffeelint
cppcheck
credo
csslint
detekt
eslint
findbugs
findbugssec

rubocop
scalastyle
scsslint
shellcheck
sonarscharp
spotbugs
SQLint
stylelint
swiftlint
tailor
tslint
tsqllint

Tool-specific configurations

Although Codacy tries to detect which language is used on each source code file, some false positives may occur. The tools below support specific configurations to specify the language or language version used in the source code files that you're analyzing.

Cppcheck

If you're using Cppcheck to analyze C or C++ source code files, add the following configuration to your Codacy configuration file to define the programming language you're using. The supported languages are c and c++:

---
engines:
  cppcheck:
    language: c++

PHP CodeSniffer

If you're using the PHP Compatibility coding standard for PHP_CodeSniffer, add the following configuration to your Codacy configuration file to define the PHP version you're using:

---
engines:
  phpcs:
    php_version: 5.5

Legacy Pylint 1.9.*

If you're using the legacy Pylint 1.9.* to analyze Python source code files, add the following configuration to your Codacy configuration file to define the Python language version you're using. The supported versions are 2 and 3:

---
engines:
  pylint:
    python_version: 2

Tip

If you're using Python 3.4.* or later as your programming language, we recommend that you disable the tool Pylint and enable the tool Pylint (Python 3) on your repository Code patterns page instead. For more information see What's New in Pylint 2.0.
