eslint-path-formatter

ESLint formatter that displays absolute error path with row/column on one line.

A console formatter cloned from jshint-path-reporter that is similar to the default output from JSHint, except the report displays absolute file paths with the row/column appended in a parsable format.

This allows convenient use of ESLint from within tools that apply a filter RegExp to console views to turn error lines into clickable links to instantly navigate to the error location.

Source-map

There is support for source-maps; if a //@ sourceMappingURL is found the reported error position is mapped to the original source file. This works great with output from compilers like TypeScript or build tools like grunt-concat-sourcemap.

WebStorm

This reporter is tested and actively used in WebStorm with eslint-grunt but will work with and implementation. For maximum effect have a output filter configured in its edit-tool-dialog of the tool you run, something like:

$FILE_PATH$[ \t]*[:;,\[\(\{<]$LINE$(?:[:;,\.]$COLUMN$)?.*

Usage

Install from NPM

 $ npm install eslint-path-formatter

Then pass the path to the module as the formatter option (see the ESLint docs). It is a bit odd but this is how ESLint finds the module.

Works with ESLint >= 0.1.0 (cli oapi), or use any recent wrapper, like:

• eslint-grunt
• grunt-eslint

For example using grunt:

grunt.initConfig({
	// when using eslint-grunt:
	eslint: {
		options: {
			formatter: './node_modules/eslint-path-formatter'
		}),
		source: {
			//..
		}
	},
	// when using grunt-eslint:
	eslint: {
		options: {
			format: './node_modules/eslint-path-formatter'
		}),
		source: {
			//..
		}
	}
});

Options

Use these on the exported value (crude but effective):

Disable ANSI colouring

For low-tech displays and pure text.

require('eslint-path-formatter').options.color = false;

//old options
require('eslint-path-formatter').color(false);

Disable sourcemap lookup

require('eslint-path-formatter').options.sourcemap = false;

Example output

Looks very similar to jshint-path-reporter:

WebStorm (with link filter and darcula theme):

History

• 0.1.1 - Added test against grunt-eslint
• 0.1.0 - Cloned from jshint-path-reporter

Build

Install development dependencies in your git checkout:

Build and run tests:

$ grunt
