Features#

  • The executable parameters now accept a ! prefix, indicating to run a separate executable instead of Python in the context. (#75)

Deprecations and Removals#

  • pip_run.launch.with_path now expects the literal command to be passed and no longer injects the sys.executable. For compatibility, pass the executable in the params or wrap the params in something like pip_run.launch.infer_cmd. (#75)

v11.0.0#

IPython inference now uses a different variable and an explicit string value to disable inference. Instead of PIP_RUN_INFER_IPYTHON=0, use PIP_RUN_IPYTHON_MODE=ignore.

v10.2.0#

#67: Now if ipython is included in the dependencies, it will be used as the default interactive interpreter (implying -m IPython).

v10.1.1#

#73: Added missing implicit test dependencies on setuptools and wheel (revealed by virtualenv 20.23.0).

v10.1.0#

#72: Now the bin directory in the target is inserted at the front of the PATH variable, making scripts available as installed by packages.

v10.0.7#

#70: Avoid OSError when a parameter to Python exceeds the allowed filename length.

v10.0.6#

Fixed EncodingWarnings.

v10.0.5#

#69: Fixed handling of inferred Python args.

v10.0.4#

#68: Fixed FileNotFoundError in persistent mode.

v10.0.3#

#66: Fixed regression in sitecustomize generation where pathlib objects were being rendered.

v10.0.2#

#65: Tests that require connectivity are now tagged with the network marker.

v10.0.1#

#65: Tests that require connectivity to the Internet now are skipped.

v10.0.0#

Removed launch.with_path_overlay, unused in this project.

Removed explicit parsing of .pth files, redundant to the use of sitecustomize.

Removed commands.parse_script_args (use separate instead).

Removed processing of JYTHONPATH as Jython is Python 2 only.

Removed commands.separate_dash.

v9.5.0#

Modernized path handling using pathlib (internal refactoring).

Renamed commands.parse_script_args to separate, with an alias for compatibility.

Restored coverage in tests.

v9.4.0#

#64: Switch to platformdirs for resolving the cache dir.

v9.3.0#

#52: pip-run now honors a PIP_RUN_MODE.

v9.2.1#

#62: Fixed minimum dependency on more_itertools to match usage.

v9.2.0#

#60: pip-run additionally supports the “limited requirements” in comments in a script.

v9.1.0#

#57: pip-run no longer requires a -- separator when the first argument to Python is an extant Python script.

v9.0.0#

#58: pip-run now sets PIP_QUIET=1 when invoking pip to install packages. To see the pip installer output during installation, pass -v and in general one additional v to achieve the prior behavior. It is no longer necessary to pass -q to suppress the installer output.

v8.8.2#

Packaging refresh.

v8.8.1#

Packaging refresh.

v8.8.0#

Expose pip_run.launch.inject_sitecustomize.

#55: Suppressed deprecation warning in test suite.

v8.6.0#

#53: read-deps script now accepts a --separator argument accepting arbitrary separators or any of the named separators:

  • newline

  • space

  • null

v8.5.1#

Updated build to exclude ‘examples’, not intended to be installed.

v8.5.0#

Removed dependency on pkg_resources. Just importing that module mucks with sys.path and causes problems.

v8.4.3#

Refreshed package metadata.

v8.4.2#

Refreshed package metadata.

v8.4.1#

#49: Declare dependency on packaging.

v8.4.0#

#47: read_deps now errors on non-existent files.

v8.2.1#

#46: Fixed AttributeError in read-deps.

v8.2.0#

Add support for reading deps from Jupyter Notebooks.

v6.3.0#

Add support for reading deps from Jupyter Notebooks.

v8.1.0#

v6.2.0#

#43: Removed workaround for pip 4106. Project now requires pip 19.3 or later.

v8.0.0#

#41: Removed support for __dependency_links__ in scripts. Instead, use PEP 508 syntax. For example, to run a script requiring requests at master:

__requires__ = ['requests @ git+https://github.com/requests/requests']

v6.1.0#

  • semver deviation *

#41: Removed support for __dependency_links__ in scripts. Instead, use PEP 508 syntax.

For example, to run a script requiring requests at master:

__requires__ = ['requests @ git+https://github.com/requests/requests']

v7.0.1#

Updated readme to remove setup_requires as a targeted use-case.

v7.0.0#

Project now requries Python 3.6 or later.

v6.0.0#

#39: Removed pip_run.deps.on_sys_path, originally intended for API-use for making packages available at run time in the same process.

5.3#

#36: Instead of soliciting the environment variable, the workaround for pip #4106 is now automatically applied, but only when it is needed.

5.2#

#36: Allow bypass of workaround for pip #4106 by setting PIP_RUN_NO_PATCH_PREFIX.

5.1#

  • Updated documentation.

5.0#

#34: Renamed project from rwt to pip-run.

4.4.3#

Update README to reflect project rename.

4.4.2#

#32: Fix regression in the 4.2 release where rwt sometimes fails to install some local packages.

4.4.1#

Fixed issue with file encoding declaration in future f-string handling.

4.4#

#30: Support reading deps from scripts with f-strings on older Pythons.

4.3#

#29: Unconditionally honor .pth files in installed packages.

4.2#

#28: Avoid error when arguments to pip install existed but did not indicate any packages to install.

4.1#

Added support for Jython by using JYTHONPATH instead of PYTHONPATH when on Jython.

4.0.1#

Use io.open in scripts reader for better Jython compatibility. See Jython 2696 for more info.

4.0#

Dropped support for injecting modules to sys.path when Setuptools is older than 19.6.2 (presumed unused).

Package now uses Setuptools declarative config and thus will not install from sdist without Setuptools 30.3 or later.

3.3#

Added support for pip 10, including addressing #25. As a side benefit, warnings are no longer issued when no requirements are supplied.

3.2#

Added rwt.read-deps command.

3.1#

#24: Add support for __dependency_links__.

#23: Fix test failures on Windows.

3.0#

Minor incompatibilty - DepsReader.read no longer accepts a var_name parameter.

#19: DepsReader.read and DepsReader.try_read now return a scripts.Dependencies instance, which always has an index_url attribute whose value will reflect the value of __index_url__ from the script (if present) or None otherwise.

#19: For standalone scripts, if __index_url__ is indicated, it will be used to resolve dependencies.

2.16#

#18: More fully support __requires__ syntax as supported by pkg_resources. This change had the unintended side-effect of disallowing full dependency links (URLs) in __requires__. See #22 for details.

Updated package from skeleton.

2.15.1#

Issue #15: Fixed issue where rwt would crash in environments where pip’s vendored dependencies (namely pkg_resources) were unbundled.

2.15#

Issue #14: Added workaround for pip #4106 such that rwt now runs on Homebrew Python and other environments where a distutils prefix is defined.

2.14#

Added support for excluding already installed packages, but only when requirements are not specified in a requirements.txt file. Inspired by conversations at HackIllinois and Issue #13.

2.13#

Issue #10: When launching the target subprocess, pass through the exit code.

Now renders normal output from pip install.

2.12#

Allow args to rwt.run function to be passed directly.

2.11#

Issue #1: Inject a sitecustomize into the install path to work around the lack of -nspkg.pth execution. Skip the execution on Python 3.3 and later, as it will degrade the behavior in those environments as indicated in #5.

2.10#

Issue #9: Intercept the --help argument if specified rather than passing that to pip install.

2.9#

Issue #8: Add a console entrypoint, so one can invoke simply rwt.

2.8#

Issue #7: Extract entries from .pth files in the temporary install folder and include those values in PYTHONPATH when launching the subprocess.

2.7.1#

Issue #6: Only augment but don’t replace PYTHONPATH.

2.7#

Issue #4: No longer use execve because it will suppress the cleanup code after the child exits. Instead, trap the interrupt in the parent process and suppress it.

2.6#

Issue #3: rwt now relies on execve to overlay the child process over the current one.

2.5#

Allow dependencies to be declared in the file in the parameters to the Python interpreter, even if other parameters are supplied. Allows for invocation like:

rwt -- -i myscript.py

2.4.2#

Fixed issue in __requires__ parsing when script contained attribute assignment.

2.4.1#

Restored simple python launch process.

2.4#

Added support for resolving dependencies declared in __requires__ in the script.

2.3#

New technique uses PYTHONPATH and subprocess to launch any arbitrary Python process.

2.2#

Add support for entry points on older versions of setuptools.

2.1#

Add support for pkg_resources entry points in added modules.

2.0#

python -m rwt now has a new signature, requiring a full list of args to pip install and a separate script to execute, separated by “–“.

1.0#

Initial implementation. Basic dependency context for running a script.
