del-paths

Create an array of ignore paths suitable for use with the del module from a file or folder path.

Installation

npm install del-paths

Usage

const del = require('del');
const delPaths = require('del-paths')({ debug: true });
const gulp = require('gulp');
const minimist = require('minimist');
 
const argv = minimist(process.argv.slice(2));
 
gulp.task('clean', function taskClean() {
  const BOWER_PATH = '.tmp/assets/bower_components';
  const CLEAN_EXCEPTIONS = (argv.cleanTempVendor === true);
  const VENDOR_PATH = '.tmp/assets/vendor';
  var sourceGlobs = ['.tmp/**'];
  if (CLEAN_EXCEPTIONS !== true) {
    sourceGlobs = sourceGlobs.concat(
      delPaths.ignore([BOWER_PATH, VENDOR_PATH]).paths(),
      // delPaths doesn't know if a path is to a file or folder, so it
      // can't automatically ignore all descendants. So, manually add
      // descendant ignoring for folders.
      '!' + BOWER_PATH + '/**',
      '!' + VENDOR_PATH + '/**'
    );
  }
  return del(sourceGlobs);
})
 
// delPaths.ignore([BOWER_PATH, VENDOR_PATH]).paths() =>
// [
//   '!.tmp',
//   '!.tmp/assets',
//   '!.tmp/assets/bower_components',
//   '!.tmp/assets/vendor'
// ]

API

delPaths([options])

options

Type: Object

options.debug

Type: Boolean

Default: false

The initial state for debug mode. Setting this to true will log additional messages to the console during execution.

See also enableDebug in delPaths.debug(enableDebug).

delPaths.debug(enableDebug)

Toggle debug mode on or off.

Returns itself for method chaining.

enableDebug

Type: Boolean

Default: false

Setting this to true will log additional messages to the console during execution.

delPaths.ignore(paths[, options])

Adds the path and its ancestors to an internal list of paths. Each path will only appear once in the list.

Returns itself for method chaining.

paths

Type: String or Array (of Strings)

Paths that you want the del module to ignore.

1. If a path doesn't already start with !, it will be added
2. Slashes will be normalized. Any backward slashes (\) will be replaced with forward slashes (/)
3. Trailing slashes will be removed

This method does not handle glob patterns, so they will be skipped.

options

Type: Object

options.sort

Type: Boolean

Default: false

A boolean indicationg whether or not the method should sort the internal list of paths if the method modifies the list. By default, this is turned off since delPaths.paths() will return a sorted list.

delPaths.paths()

Returns the internal list of paths as an array of strings, sorted alphabetically.

delPaths.reset()

Empties the internal list of paths.

Returns itself for method chaining.
