Travis will also fail\nthe build if some problems detected.\n\n### OS X\n\n```sh\n$ brew tap veelenga/tap\n$ brew install ameba\n```\n\n### Docker\n\nBuild the image:\n\n```sh\n$ docker build -t crystal-ameba/ameba .\n```\n\nTo use the resulting image on a local source folder, mount the current (or target) directory into `/src`:\n\n```sh\n$ docker run -v $(pwd):/src crystal-ameba/ameba\n```\n\nAlso available on DockerHub: https://hub.docker.com/r/veelenga/ameba\n\n### From sources\n\n```sh\n$ git clone https://github.com/crystal-ameba/ameba && cd ameba\n$ make install\n```\n\n## Configuration\n\nDefault configuration file is `.ameba.yml`.\nIt allows to configure rule properties, disable specific rules and exclude sources from the rules.\n\nGenerate new file by running `ameba --gen-config`.\n\n### Sources\n\n**List of sources to run Ameba on can be configured globally via:**\n\n- `Globs` section - an array of wildcards (or paths) to include to the\n inspection. Defaults to `%w(**/*.cr !lib)`, meaning it includes all project\n files with `*.cr` extension except those which exist in `lib` folder.\n- `Excluded` section - an array of wildcards (or paths) to exclude from the\n source list defined by `Globs`. Defaults to an empty array.\n\nIn this example we define default globs and exclude `src/compiler` folder:\n\n``` yaml\nGlobs:\n - **/*.cr\n - !lib\n\nExcluded:\n - src/compiler\n```\n\n**Specific sources can be excluded at rule level**:\n\n``` yaml\nStyle/RedundantBegin:\n Excluded:\n - src/server/processor.cr\n - src/server/api.cr\n```\n\n### Rules\n\nOne or more rules, or a one or more group of rules can be included or excluded\nvia command line arguments:\n\n```sh\n$ ameba --only Lint/Syntax # runs only Lint/Syntax rule\n$ ameba --only Style,Lint # runs only rules from Style and Lint groups\n$ ameba --except Lint/Syntax # runs all rules except Lint/Syntax\n$ ameba --except Style,Lint # runs all rules except rules in Style and Lint groups\n```\n\nOr through the configuration file:\n\n``` yaml\nStyle/RedundantBegin:\n Enabled: false\n```\n\n### Explain issues\n\nAmeba allows you to dig deeper into an issue, by showing you details about the issue\nand the reasoning by it being reported.\n\nTo be convenient, you can just copy-paste the `PATH:line:column` string from the\nreport and paste behind the `ameba` command to check it out.\n\n```sh\n$ ameba crystal/command/format.cr:26:83 # show explanation for the issue\n$ ameba --explain crystal/command/format.cr:26:83 # same thing\n```\n\n### Inline disabling\n\nOne or more rules or one or more group of rules can be disabled using inline directives:\n\n```crystal\n# ameba:disable Style/LargeNumbers\ntime = Time.epoch(1483859302)\n\ntime = Time.epoch(1483859302) # ameba:disable Style/LargeNumbers, Lint/UselessAssign\n\ntime = Time.epoch(1483859302) # ameba:disable Style, Lint\n```\n\n## Editors & integrations\n\n * Vim: [vim-crystal](https://github.com/rhysd/vim-crystal), [Ale](https://github.com/w0rp/ale)\n * Emacs: [ameba.el](https://github.com/crystal-ameba/ameba.el)\n * Sublime Text: [Sublime Linter Ameba](https://github.com/epergo/SublimeLinter-contrib-ameba)\n * VSCode: [vscode-crystal-ameba](https://github.com/crystal-ameba/vscode-crystal-ameba)\n * Codacy: [codacy-ameba](https://github.com/codacy/codacy-ameba)\n * GitHub Actions: [github-action](https://github.com/crystal-ameba/github-action)\n\n## Credits & inspirations\n\n- [Crystal Language](https://crystal-lang.org)\n- [Rubocop](https://rubocop.readthedocs.io/en/latest/)\n- [Credo](http://credo-ci.org/)\n- [Dogma](https://github.com/lpil/dogma)\n\n## Contributors\n\n- [veelenga](https://github.com/veelenga) Vitalii Elenhaupt -

Travis will also fail\nthe build if some problems detected.\n\n### OS X\n\n```sh\n$ brew tap veelenga/tap\n$ brew install ameba\n```\n\n### Docker\n\nBuild the image:\n\n```sh\n$ docker build -t crystal-ameba/ameba .\n```\n\nTo use the resulting image on a local source folder, mount the current (or target) directory into `/src`:\n\n```sh\n$ docker run -v $(pwd):/src crystal-ameba/ameba\n```\n\nAlso available on DockerHub: https://hub.docker.com/r/veelenga/ameba\n\n### From sources\n\n```sh\n$ git clone https://github.com/crystal-ameba/ameba && cd ameba\n$ make install\n```\n\n## Configuration\n\nDefault configuration file is `.ameba.yml`.\nIt allows to configure rule properties, disable specific rules and exclude sources from the rules.\n\nGenerate new file by running `ameba --gen-config`.\n\n### Sources\n\n**List of sources to run Ameba on can be configured globally via:**\n\n- `Globs` section - an array of wildcards (or paths) to include to the\n inspection. Defaults to `%w(**/*.cr !lib)`, meaning it includes all project\n files with `*.cr` extension except those which exist in `lib` folder.\n- `Excluded` section - an array of wildcards (or paths) to exclude from the\n source list defined by `Globs`. Defaults to an empty array.\n\nIn this example we define default globs and exclude `src/compiler` folder:\n\n``` yaml\nGlobs:\n - **/*.cr\n - !lib\n\nExcluded:\n - src/compiler\n```\n\n**Specific sources can be excluded at rule level**:\n\n``` yaml\nStyle/RedundantBegin:\n Excluded:\n - src/server/processor.cr\n - src/server/api.cr\n```\n\n### Rules\n\nOne or more rules, or a one or more group of rules can be included or excluded\nvia command line arguments:\n\n```sh\n$ ameba --only Lint/Syntax # runs only Lint/Syntax rule\n$ ameba --only Style,Lint # runs only rules from Style and Lint groups\n$ ameba --except Lint/Syntax # runs all rules except Lint/Syntax\n$ ameba --except Style,Lint # runs all rules except rules in Style and Lint groups\n```\n\nOr through the configuration file:\n\n``` yaml\nStyle/RedundantBegin:\n Enabled: false\n```\n\n### Explain issues\n\nAmeba allows you to dig deeper into an issue, by showing you details about the issue\nand the reasoning by it being reported.\n\nTo be convenient, you can just copy-paste the `PATH:line:column` string from the\nreport and paste behind the `ameba` command to check it out.\n\n```sh\n$ ameba crystal/command/format.cr:26:83 # show explanation for the issue\n$ ameba --explain crystal/command/format.cr:26:83 # same thing\n```\n\n### Inline disabling\n\nOne or more rules or one or more group of rules can be disabled using inline directives:\n\n```crystal\n# ameba:disable Style/LargeNumbers\ntime = Time.epoch(1483859302)\n\ntime = Time.epoch(1483859302) # ameba:disable Style/LargeNumbers, Lint/UselessAssign\n\ntime = Time.epoch(1483859302) # ameba:disable Style, Lint\n```\n\n## Editors & integrations\n\n * Vim: [vim-crystal](https://github.com/rhysd/vim-crystal), [Ale](https://github.com/w0rp/ale)\n * Emacs: [ameba.el](https://github.com/crystal-ameba/ameba.el)\n * Sublime Text: [Sublime Linter Ameba](https://github.com/epergo/SublimeLinter-contrib-ameba)\n * VSCode: [vscode-crystal-ameba](https://github.com/crystal-ameba/vscode-crystal-ameba)\n * Codacy: [codacy-ameba](https://github.com/codacy/codacy-ameba)\n * GitHub Actions: [github-action](https://github.com/crystal-ameba/github-action)\n\n## Credits & inspirations\n\n- [Crystal Language](https://crystal-lang.org)\n- [Rubocop](https://rubocop.readthedocs.io/en/latest/)\n- [Credo](http://credo-ci.org/)\n- [Dogma](https://github.com/lpil/dogma)\n\n## Contributors\n\n- [veelenga](https://github.com/veelenga) Vitalii Elenhaupt -

Travis will also fail\nthe build if some problems detected.\n\n### OS X\n\n```sh\n$ brew tap veelenga/tap\n$ brew install ameba\n```\n\n### Docker\n\nBuild the image:\n\n```sh\n$ docker build -t crystal-ameba/ameba .\n```\n\nTo use the resulting image on a local source folder, mount the current (or target) directory into `/src`:\n\n```sh\n$ docker run -v $(pwd):/src crystal-ameba/ameba\n```\n\nAlso available on DockerHub: https://hub.docker.com/r/veelenga/ameba\n\n### From sources\n\n```sh\n$ git clone https://github.com/crystal-ameba/ameba && cd ameba\n$ make install\n```\n\n## Configuration\n\nDefault configuration file is `.ameba.yml`.\nIt allows to configure rule properties, disable specific rules and exclude sources from the rules.\n\nGenerate new file by running `ameba --gen-config`.\n\n### Sources\n\n**List of sources to run Ameba on can be configured globally via:**\n\n- `Globs` section - an array of wildcards (or paths) to include to the\n inspection. Defaults to `%w(**/*.cr !lib)`, meaning it includes all project\n files with `*.cr` extension except those which exist in `lib` folder.\n- `Excluded` section - an array of wildcards (or paths) to exclude from the\n source list defined by `Globs`. Defaults to an empty array.\n\nIn this example we define default globs and exclude `src/compiler` folder:\n\n``` yaml\nGlobs:\n - **/*.cr\n - !lib\n\nExcluded:\n - src/compiler\n```\n\n**Specific sources can be excluded at rule level**:\n\n``` yaml\nStyle/RedundantBegin:\n Excluded:\n - src/server/processor.cr\n - src/server/api.cr\n```\n\n### Rules\n\nOne or more rules, or a one or more group of rules can be included or excluded\nvia command line arguments:\n\n```sh\n$ ameba --only Lint/Syntax # runs only Lint/Syntax rule\n$ ameba --only Style,Lint # runs only rules from Style and Lint groups\n$ ameba --except Lint/Syntax # runs all rules except Lint/Syntax\n$ ameba --except Style,Lint # runs all rules except rules in Style and Lint groups\n```\n\nOr through the configuration file:\n\n``` yaml\nStyle/RedundantBegin:\n Enabled: false\n```\n\n### Explain issues\n\nAmeba allows you to dig deeper into an issue, by showing you details about the issue\nand the reasoning by it being reported.\n\nTo be convenient, you can just copy-paste the `PATH:line:column` string from the\nreport and paste behind the `ameba` command to check it out.\n\n```sh\n$ ameba crystal/command/format.cr:26:83 # show explanation for the issue\n$ ameba --explain crystal/command/format.cr:26:83 # same thing\n```\n\n### Inline disabling\n\nOne or more rules or one or more group of rules can be disabled using inline directives:\n\n```crystal\n# ameba:disable Style/LargeNumbers\ntime = Time.epoch(1483859302)\n\ntime = Time.epoch(1483859302) # ameba:disable Style/LargeNumbers, Lint/UselessAssign\n\ntime = Time.epoch(1483859302) # ameba:disable Style, Lint\n```\n\n## Editors & integrations\n\n * Vim: [vim-crystal](https://github.com/rhysd/vim-crystal), [Ale](https://github.com/w0rp/ale)\n * Emacs: [ameba.el](https://github.com/crystal-ameba/ameba.el)\n * Sublime Text: [Sublime Linter Ameba](https://github.com/epergo/SublimeLinter-contrib-ameba)\n * VSCode: [vscode-crystal-ameba](https://github.com/crystal-ameba/vscode-crystal-ameba)\n * Codacy: [codacy-ameba](https://github.com/codacy/codacy-ameba)\n * GitHub Actions: [github-action](https://github.com/crystal-ameba/github-action)\n\n## Credits & inspirations\n\n- [Crystal Language](https://crystal-lang.org)\n- [Rubocop](https://rubocop.readthedocs.io/en/latest/)\n- [Credo](http://credo-ci.org/)\n- [Dogma](https://github.com/lpil/dogma)\n\n## Contributors\n\n- [veelenga](https://github.com/veelenga) Vitalii Elenhaupt -
