InVEST Build Framework
======================
Scripts, hooks, and instructions for creating a binary build of InVEST.
Requirements
------------
* PyInstaller (see PyInstaller project for own OS-specific dependencies)
* InVEST3
Usage
-----
Currently must call pyinstaller from same directory as spec file (b/c of spec file)
.. code:: shell
$ pyinstaller invest.spec
Distributable build stored in top-level `dist/` folder.
Planning
--------
* Support for Linux
* Support for Windows
* Support for Mac OSX
* Scripts to install InVEST dependencies
Notes on PyInstaller
--------------------
Repository: https://github.com/pyinstaller/pyinstaller
Documentation: http://pythonhosted.org/PyInstaller/
Definitions
~~~~~~~~~~~
scripts: the python scripts named at command line
pure: pure python modules needed by the scripts
binaries: non-python modules needed by the scripts
Stage 1: Dependency Analysis
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
.. code:: python
a = Analysis() # contains lists of scripts, pure, and binaries
hooks.hookutils functions:
* get_package_paths(package)
* hiddenimports = collect_submodules(package)
* datas = collect_data_files(package)
.. code:: python
MERGE( [ (a, 'script_name', 'exec_name'), (b, 'b', 'b'), ... ] )
MERGE is used in multi-package bundles.
Stage 2: Python File Compression
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
.. code:: python
pyz = PYZ(a.pure) # contains the modules listed in a.pure
Stage 3: Create Executable Scripts
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
.. code:: python
# contains what will be the executable file 'myscript'
exe = EXE(a.scripts, a.binaries, a.zipfiles, a.datas, pyz, name="myscript", exclude_binaries=1)
Stage 4: Collect Files into Distributable Application
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
.. code:: python
# creates the output folder
COLLECT(exe, a.binaries, a.zipfiles, a.datas, name="dist")
Notes on Preparing InVEST Repo for PyInstaller
----------------------------------------------
In Setup.py's setup() function:
include_package_data=True,
Add MANIFEST.in with following:
recursive-include invest_natcap/
Add additional elif block to iui.executor import switch statement
from importlib import import_module
elif getattr(sys, 'frozen', False) and getattr(sys, '_MEIPASS', False):
model = import_module(module)
model_name = os.path.splitext(os.path.basename(module))[0]
LOGGER.debug('Loading %s in frozen environment', model)
