cjs-rename

Inspired by https://github.com/timruffles/misnomer/blob/master/README.md.

Given a module a bad name that is used all over your codebase and tests? Sounds like you want to rename a CJS module, and this here module can do that for you:

> cjs-rename lib/some-bad-name.js lib/some-good-name.js
 
Moving:
- moved lib/some-bad-name.js to lib/some-good-name.js
 
Fixing:
- [1] lib/foo/bad.js
- [1] lib/foo/qux.js
- [1] test/foo/bar.js

And magically, where you saw:

require('../../lib/some-bad-name');

You'll now find:

require('../../lib/some-good-name');

Search by filename

Don't want to type out filepaths? Then add the -s flag to do a search.

Notice how it moves both files in the lib and test folders.

> cjs-rename -s some-bad-name some-good-name
 
Moving:
- moved lib/some-bad-name.js to lib/some-good-name.js
- moved test/some-bad-name.js to test/some-good-name.js
 
Fixing:
- [1] lib/foo/bad.js
- [1] lib/foo/qux.js
- [1] test/foo/bar.js

Drymode

Drymode will show you the affect the command will have, without actually saving any changes. Just add the -d flag.

cjs-rename -s -d old new
Drymode: Will not save changes
 
Moving:
- moved lib/folder/old.js to lib/folder/new.js
-moved test/old.js to test/new.js
 
Fixing:
- [1] lib/folder/foo.js
- [1] test/foo.js

Rename constructor

Create a new Rename instance.

Can be called with or without new.

Parameters:

• options (object)
  • from (string) required
  • to (string) required
  • cwd (string)

  • mode (string)

Example:

var rename = Rename({
    from: 'old',
    to: 'new',
    cwd: '/home/project/folder',
    mode: 'search'
});

rename.run

Will move and rename files. Will automatically call rename.save unless you specify drymode: true in the options.

Parameters:

• [fn] (function) : optional callback with signature fn(err, changes)

Example:

rename.run(function (err, changes) {
    if (err) {
        console.log('Error', err);
    } else {
        console.log(changes);
    }
});

rename.save

Save changes to disk.

Paramters:

• [fn] (function) : optional callback with signature fn(err)

        console.log('Error', err);
    } else {
        console.log('Saved changes');
    }
});

• This will only search through files with the .js and .coffee extensions.
• It will ignore any node_modules folders.
