Introduction

This document aims to enable anyone to quickly get up to speed on how to:

  1. Build a Windows .exe for the application
  2. Package that .exe into an .msi file for distribution
  3. Handle the files generated so the application automatically detects new available versions and asks the user to upgrade.

Note that for Windows only a 32-bit application is supported at this time. This is principally due to the Windows Registry handling in config.py.

Environment

You will need several pieces of software installed, or the files from their .zip archives, in order to build the .exe and generate the .msi

  1. WiX Toolset: 3.11.2 is the most recently tested version.

  2. WinSparkle: winsparkle.dll and winsparkle.pdb from the release's .zip file. v0.7.0 is the most recently tested version. Copy the two files, found at <zip file>\<version>\Release, into your checkout of the EDMC git files.

  3. Windows SDK. This is needed for the internationalisation support in EDMC. Windows 10 SDK, version 1903 (10.0.18362.1) is the most recently tested version. Technically you only need the following components: MSI Tools, Windows SDK for Desktop C++ x86 Apps (which will auto-select some others). NB: If you have need to uninstall this it's "Windows Software Development Kit - Windows 10.0.18362.1" in "Apps & Features", not "Windows SDK AddOn".

  4. Python: 32-bit version of Python 3.7 for Windows. v3.7.7 is the most recently tested version. You need the Windows x86 executable installer file, for the 32-bit version.

    1. You'll now need to 'pip install' several python modules
      1. pip install certifi==2019.9.11 (because a later version doesn't work with py2exe, causing cacert.pem to not be found)
      2. pip install requests
      3. pip install watchdog

  5. py2exe: You need a pre-release version, 0.9.4.0, see this py2exe issue

    1. pip install py2exe-0.9.4.0-cp37-none-win32.whl
    2. pip install keyring==19.2.0 (because newer tries to get importlib_metadata in a way that doesn't work)

    As dependencies also get pulled in here's a list of what ended up in site-packages, and their versions:

     cachetools-4.1.0.dist-info
 certifi-2019.9.11.dist-info
 chardet-3.0.4.dist-info
 entrypoints-0.3.dist-info
 future-0.18.2-py3.7.egg-info
 importlib_metadata-1.6.1.dist-info
 keyring-19.2.0.dist-info
 pathtools-0.1.2-py3.7.egg-info
 pefile-2019.4.18-py3.7.egg-info
 py2exe-0.9.4.0.dist-info
 pywin32_ctypes-0.2.0.dist-info
 requests-2.23.0.dist-info
 setuptools-41.2.0.dist-info
 urllib3-1.25.9.dist-info
 watchdog-0.10.2-py3.7.egg-info
 zipp-3.1.0.dist-info

If you are using different versions of any of these tools then please ensure that the paths where they're installed match the associated lines in setup.py. i.e. if you're using later WiX you might need to edit the WIXPATH line, and likewise the SDKPATH line if you're using a later Windows SDK kit.

Necessary Edits

There are some things that you should always change before running your own version of EDMC

  1. The Frontier CAPI client ID. This is hardcoded in companion.py, but can be overridden by setting a CLIENT_ID environment variable.

There are other things that you should probably change, but can get away with leaving at the upstream values, especially if you only you are going to use the resulting .exe and/or .msi files. But realise that the resulting program will still try to check for new versions at the main URL unless you change that.

  1. Copyright and 'Company' texts. These are in setup.py. Search for 'copyright' and 'company_name'.

  2. Location of release files. To change this edit setup.py. Look for the appcast.write() statement and change the url="... line.

  3. Application names, version and URL the file with latest release information. These are all in the config.py file. See the from config import ... lines in setup.py.

    1. appname: The short appname, e.g. 'EDMarketConnector'
    2. applongname: The long appname, e.g. 'E:D Market Connector'
    3. appcmdname: The CLI appname, e.g. 'EDMC'
    4. appversion: The current version, e.g. '3.5.0.0'
    5. update_feed: The URL where the application looks for current latest version information. This URL should be hosting a renamed (so the full URL doesn't change over application versions) version of the appcast_win_.xml file. The original upstream value is https://marginal.org.uk/edmarketconnector.xml

Packaging & Installer Generation

You'll want to do the .exe and .msi generation in a cmd.exe window, not e.g. a 'Git bash' window.

Assuming the correct python.exe is associated with .py files then simply run:

	setup.py py2exe

else you might need this, which assumes correct python.exe is in your PATH:

	python.exe setup.py py2exe

else you'll have to specify the path to python.exe:

	"%LOCALAPPDATA%\Programs\Python\Python37-32\python.exe" setup.py py2exe

Output will be something like (... denoting parts elided for brevity):

	running py2exe
	...
	Building 'dist.win32\EDMC.exe'.
	Building 'dist.win32\EDMarketConnector.exe'.
	Building shared code archive 'dist.win32\library.zip'.

	Done

You should now have one new/updated folder dist.win32 and two new files (version number dependent): EDMarketConnector_win_350.msi and appcast_win_350.xml. If you want to just check the generated .exe files then they're in that dist.win32 folder.

Distribution

Put the EDMarketConnector_win_<version>.msi file in place where you're releasing the files. Put the appcast_win_<version>.xml file where it will be served under the URL you specified in the update_feed you set in config.py.
