Author message:

This package is being phased out in favour of fluid-lint-all.

fluid-grunt-lint-all

This grunt plugin provides a combined rollup command that runs all lint checks typically used in Fluid projects. To add it to your package, use a command like:

npm install fluid-grunt-lint-all --save-dev

Once the plugin has been installed, it may be enabled inside your Gruntfile as shown in the following example:

"use strict";
module.exports = function (grunt) {
    grunt.config.init({
        lintAll: {
            sources: {
                js:    ["./src/js/**/*.js", "tests/js/**/*.js", "./*.js", "!./src/lib/**/*.js"]
            }
        }
    });
    grunt.loadNpmTasks("fluid-grunt-lint-all");
    grunt.registerTask("lint", "Perform all standard lint checks.", ["lint-all"]);
 
    grunt.registerTask("default", ["lint"]);
};
 

By default, this plugin takes care of letting all of the sub-tasks know where to look for Javascript, JSON, JSON5, and Markdown files, so you only need to configure the lintAll block as shown above. If you need to exclude content for a single file type, add a negated pattern at the end of the relevant source block, as show here.

"use strict";
module.exports = function (grunt) {
    grunt.config.init({
        lintAll: {
            sources: {
                js:    ["./src/js/**/*.js", "tests/js/**/*.js", "./*.js", "!./src/lib/**/*.js"]
            }
        }
    });
    grunt.loadNpmTasks("fluid-grunt-lint-all");
    grunt.registerTask("lint", "Perform all standard lint checks.", ["lint-all"]);
 
    grunt.registerTask("default", ["lint"]);
};

Running the Checks

Once you have installed the plugin and updated your Gruntfile.js, you should be able to run the lint-all command from the root of your repository, as in grunt lint-all.

Configuring Individual Checks

This plugin is a rollup that calls a range of individual checks. All checks support the standard src array that defines which material should be linted. For more information about the individual checks and links to their documentation, see below:

Task	Description	Documentation
eslint	Run both the eslint:js and eslint:md tasks (see below).	See below.
eslint:js	Check the validity and formatting of Javascript files.	grunt-eslint
eslint:md	Check the validity and formatting of Javascript code blocks in Markdown files.	eslint-plugin-markdown
json5lint	Check the validity of JSON5 files.	fluid-grunt-json5lint
jsonlint	Check the validity and formatting of JSON files.	grunt-jsonlint
lintspaces	Check for trailing carriage returns and indentation.	grunt-lintspaces
lintspaces:jsonindentation	Check the indentation of JSON files.	grunt-lintspaces
lintspaces:newlines	Check for the presence of a carriage return at the end of a file.	grunt-lintspaces
markdownlint	Check the formatting of Markdown files.	grunt-markdownlint
mdjsonlint	Check the validity and formatting of JSON code blocks within Markdown files.	(Provided by this package. See below))

Please note that many of the above checks use our standard ESLint configuration, which is available in the eslint-config-fluid. You will need to follow the installation instructions in that package before you run many of the above checks.

Customizing Configurations

Linting configurations can be customized by providing your own options in Gruntfile.js as shown in this example:

module.exports = function (grunt) {
    grunt.config.init({
        eslint: {
            js: {
                options: {
                    rules: {
                        "eol-last": "off",
                        "strict": "off",
                        "no-undef": "off"
                    }
                }
            },
            md: {
                options: {
                    rules: {
                        semi: "off"
                    }
                }
            }
        },
        json5lint: {
            options: {
                enableJSON5: true
            }
        },
        lintspaces: {
            newlines: {
                options: {
                    newline: false
                }
            },
            jsonindentation: {
                options: {
                    indentation: false
                }
            }
        },
        markdownlint: {
            options: {
                config: {
                    "first-header-h1": false,
                    "first-line-h1": false
                }
            }
        },
        "json-eslint": {
            options: {
                "rules": {
                    "comma-dangle": "off"
                }
            }
        }
    });
};

Global Ignores

All of the checks above are configured to avoid linting things like package-lock.json, coverage reports, and the contents of the top-level node_modules directory. You can override these by setting the ignores option, as shown here:

"use strict";
module.exports = function (grunt) {
    grunt.config.init({
        lintAll: {
            sources: {
                js:    ["./src/js/**/*.js", "tests/js/**/*.js", "./*.js", "!./src/lib/**/*.js"]
            },
            ignores: ["!./tests/intentionally-broken-content/**/*", "!./node_modules", "!./package-lock.json"]
        }
    });
    grunt.loadNpmTasks("fluid-grunt-lint-all");
    grunt.registerTask("lint", "Perform all standard lint checks.", ["lint-all"]);
 
    grunt.registerTask("default", ["lint"]);
};
 

Please note, ignores must be expressed as negative patterns, i.e. !./path/to/exclude/*.json. Also, Grunt's options merging will completely replace the defaults if you set a custom ignores setting. If you are trying to ignore content that corresponds to one of the file types in sources (js, json, etc.), you're better off adding your pattern(s) to a file-type-specific property. If you need to change the global ignores option, you will need to replicate any default rules (such as !/package-lock.json) in your custom ignores value.

Tasks

This package provides a few key tasks.

json-eslint

This task inspects all JSON(5) as though it were enclosed in a simple javascript fixture. This does not check for validity, but instead checks things like indentation and other code conventions.

json-parser

This tasks uses VSCode's JSON language parsing service to attempt to parse JSON files, and to return information about the location of any invalid JSON.

mdjsonlint

This task uses markdown-to-ast to extract all code blocks within markdown content. Only fenced code blocks tagged with the json or json5 language will be linted:

The following will be scanned (and report an error):
 
```json
{
  key: "not quoted"
}
```
 
The following will be scanned (and will not report an error):
 
```json5
{
    key: "not quoted"
}
```
 
The following will not be scanned:
 
```snippet
someOperation(<garbage in>) => <garbage out>
```

Each code block is linted by attempting to parse it using either JSON.parse, or the JSON5.parse method provided by the json5 library. Errors are caught and converted to a common format that includes the information needed to identify which file, line number and column number are associated with the error. Note that the first failure in a single fenced code block may prevent you from seeing subsequent errors in the same fenced code block.
