Convert Python packages into a single script
Stickytape can be used to convert a Python script and any Python modules it depends into a single-file Python script. You can tell stickytape which directories to search using the --add-python-path argument. For instance:
stickytape scripts/blah --add-python-path . > /tmp/blah-standalone
Or to output directly to a file:
stickytape scripts/blah --add-python-path . --output-file /tmp/blah-standalone
You can also point stickytape towards a Python binary that it should use sys.path from, for instance the Python binary inside a virtualenv:
stickytape scripts/blah --python-binary _virtualenv/bin/python --output-file /tmp/blah-standalone
As you might expect with a program that munges source files, there are a few caveats:
- Detection of imports is done using a fairly simple regex. For instance, things will go horribly wrong if you use have two import statements on the same line separated by a semi-colon. Similarly, imports using importlib won’t be detected.
- Anything that relies on the specific location of files will probably no longer work. In other words, __file__ probably isn’t all that useful.
- Any files that aren’t imported won’t be included. Static data that might be part of your project, such as other text files or images, won’t be included.
