grunt-trimtrailingspaces

Trim trailing spaces from each line of the selected files

Getting Started

This plugin requires Grunt ^1.1 and Node.js version to be minimum of 14.15.0, which is the active Long Term Support (LTS) version.

Add this to your project's Gruntfile.js configuration:

grunt.loadNpmTasks('grunt-trimtrailingspaces');

Then add grunt-trimtrailingspaces to your "package.json" dependencies. This can be done with:

npm install grunt-trimtrailingspaces --save-dev

Or by manually editing the package.json file by adding the following line inside devDependencies object:

  "grunt-trimtrailingspaces": "^5.0.0"

Later on it would be possible to install the plugin with the command npm install

It can be updated with the command npm update, in case there is a newer version in the npm registry.

The name to use in your own task definitions is trimtrailingspaces.

Documentation

Add an entry to your Gruntfile.js, within the initConfig object, which will define the files of which will the trailing spaces to be removed.

By using the src property for selecting files to be processed, they are replaced by the ones processed.

By setting the failIfTrimmed option to true, the grunt task will fail after trimming all files if any whitespace was removed. This is very useful for running trimtrailingspaces as a pre-commit task (in combination with grunt-githooks), because it will prevent the commit from going through which would not include the trimming changes.

The examples below are using the built-in custom filter property.

  ...

  trimtrailingspaces: {
    main: {
      src: ['public_html/js/**/*.js'],
      options: {
        filter: 'isFile',
        encoding: 'utf8',
        failIfTrimmed: false
      }
    }
  }

  ...

It is possible to save the processed files to a different location by using the files property, as shown below. The destination (key) should be a directory path in which the src files (array value) are stored. No trailing slash needed.

Please note that this method will create a flat directory of the result.

  ...

  trimtrailingspaces: {
    main: {
      files: {
        'public_html/js/trimmed': ['public_html/js/**/*.js']
      },
      filter: 'isFile',
      encoding: 'utf8'
    }
  }

  ...

For further information on how files are matched, please see the documentation of the minimatch package, as it is used underneath Grunt.

To run it:

grunt trimtrailingspaces
