docs

src

Returns an array when src is an array

mapDest(['a.txt', 'b.txt'], 'dist');
// [ { options: {}, src: 'a.txt', dest: 'dist/a.txt' },
//   { options: {}, src: 'b.txt', dest: 'dist/b.txt' } ]

dest

Creates a dest when no dest argument is passed.

mapDest('a/b/c.txt');
// [{ options: {}, src: 'a/b/c.txt', dest: 'a/b/c.txt' }]

When no dest is defined and src is an array, returns an array with generated dest paths.

mapDest(['a.txt', 'b.txt']);
// [ { options: {}, src: 'a.txt', dest: 'a.txt' },
//   { options: {}, src: 'b.txt', dest: 'b.txt' } ]

options

options.flatten

Flattens dest when no dest argument is passed:

mapDest('a/b/c.txt', {flatten: true});
// [{ options: { flatten: true }, src: 'a/b/c.txt', dest: 'c.txt' }]

options.ext

Replaces the destination extension with given ext:

mapDest('a/b/c.txt', {ext: '.foo'});
// [{ options: { ext: '.foo', extDot: 'first' },
//   src: 'a/b/c.txt',
//   dest: 'a/b/c.foo' }]

options.cwd

When cwd is defined it will be prepended to src:

mapDest('a/b/c.txt', {cwd: 'one/two'});
// [{ options: { cwd: 'one/two' },
//   src: 'one/two/a/b/c.txt',
//   dest: 'a/b/c.txt' }]

Prepends cwd to src and flattens dest:

mapDest('a/b/c.txt', {cwd: 'one/two', flatten: true});
// [{ options: { cwd: 'one/two', flatten: true },
//   src: 'one/two/a/b/c.txt',
//   dest: 'c.txt' }]

Expands tildes in cwd to make the path relative to the user's home directory:

mapDest('a/b/c.txt', {cwd: '~/one/two'});
// [{ options: { cwd: '/User/jonschlinkert/one/two', flatten: true },
//   src: 'one/two/a/b/c.txt',
//   dest: 'c.txt' }]

Expands @ in cwd to make the path relative to global npm modules:

mapDest('templates/base.hbs', {cwd: '@/boilerplate-h5bp'});
// [ { options: { cwd: '/usr/local/lib/node_modules/boilerplate-h5bp' },
//     src: '/usr/local/lib/node_modules/boilerplate-h5bp/templates/base.hbs',
//     dest: 'templates/base.hbs' } ]

options.destBase

If destBase is defined it's prepended to generated dest.

mapDest('a/b/c.txt', {destBase: 'one/two'});
// [{ options: { destBase: 'one/two' },
//   src: 'a/b/c.txt',
//   dest: 'one/two/a/b/c.txt' }]

If destBase is defined, it will be prepended to dest

mapDest('a/b/c.txt', 'foo', {destBase: 'one/two'});
// [{ options: { destBase: 'one/two' },
//   src: 'a/b/c.txt',
//   dest: 'one/two/foo/a/b/c.txt' }]

options.rename

A custom rename function can be used to modify the generated dest path.

mapDest('a/b/c.md', {
  rename: function (dest, src, opts) {
    return 'dist/' + path.basename(src) + '.html';
  }
});
// [{ options: { rename: [Function] },
//   src: 'a/b/c.md',
//   dest: 'dist/c.html' }]
