# This script freezes Frescobaldi to a standalone application without
# needing to install any dependencies.
#
# Usage:
# C:\Python27\Python freeze.py
#
# How it works:
# It creates, using cx_Freeze, a frescobaldi executable inside the frozen/
# directory, along with all used (manually specified) Python modules.
# Then the whole frescobaldi_app directory is copied and the Python scripts
# byte-compiled.
# Finally, an installer is created using the Inno Setup console-mode compiler.

# the Inno Setup console-mode compiler
iscc = 'c:\\Program Files\\Inno Setup 5\\ISCC'

# where to build the frozen program folder
target_dir = 'frozen'

# import standard modules and cx_Freeze
import imp
import os
import py_compile
import shutil
import subprocess
import sys
from cx_Freeze import Executable, Freezer

# access the frescobaldi_app package
sys.path.insert(0, '..')

# access meta-information such as version, etc.
from frescobaldi_app import appinfo

# find pypm by adding the dir of pygame to sys.path
sys.path.append(imp.find_module('pygame')[1])
