If you are more comfortable writing scripts than using UIs, you can also build your extension with code.

The script below is part of the Boilerplate RoboFont Extension, and is written to work with the other files in the repository. If you choose to organize your files differently, you will need to update the script accordingly.

'''build RoboFont Extension'''

import os
from mojo.extensions import ExtensionBundle

# get current folder
basePath = os.path.dirname(__file__)

# source folder for all extension files
sourcePath = os.path.join(basePath, 'source')

# folder with python files
libPath = os.path.join(sourcePath, 'code')

# folder with html files
htmlPath = os.path.join(sourcePath, 'documentation')

# folder with resources
resourcesPath = os.path.join(sourcePath, 'resources')

# load license text from file
# see http://choosealicense.com/ for more open-source licenses
licensePath = os.path.join(basePath, 'license.txt')
license = open(licensePath).read()

# boolean indicating if only .pyc should be included
pycOnly = False

# name of the compiled extension file
extensionFile = 'myExtension.roboFontExt'

# path of the compiled extension
buildPath = os.path.join(basePath, 'build')
extensionPath = os.path.join(buildPath, extensionFile)

# initiate the extension builder
B = ExtensionBundle()

# name of the extension
B.name = "myExtension"

# name of the developer
B.developer = 'Python Monty'

# URL of the developer
B.developerURL = 'http://youtu.be/akbflkF_1zY'

# extension icon
imagePath = os.path.join(resourcesPath, 'icon.png')
B.icon = imagePath # RF3: a path or NSImage object

# version of the extension
B.version = '0.1'

# should the extension be launched at start-up?
B.launchAtStartUp = True

# script to be executed when RF starts
B.mainScript = 'hello.py'

# script to be executed when the extension is unistalled
B.uninstallScript = 'goodbye.py'

# does the extension contain html help files?
B.html = True

# minimum RoboFont version required for this extension
B.requiresVersionMajor = '1'
B.requiresVersionMinor = '5'

# scripts which should appear in Extensions menu
B.addToMenu = [
        'path' : 'doSomething.py',
        'preferredName': 'do something',
        'shortKey' : '',
        'path' : 'doSomethingElse.py',
        'preferredName': 'do something else',
        'shortKey' : '',

# license for the extension
B.license = license

# info for Mechanic extension manager
B.repositoryURL = 'http://github.com/robodocs/rf-extension-boilerplate/'
B.summary = 'A boilerplate extension which serves as starting point for creating your own extensions.'

# compile and save the extension bundle
print('building extension...',)
B.save(extensionPath, libPath=libPath, htmlPath=htmlPath, resourcesPath=resourcesPath, pycOnly=pycOnly)

# check for problems in the compiled extension

The script uses the exact same settings as the example using the Extension Builder.
