pyfredcli 0.1.6

Pyfred
pyfred helps you create Alfred workflows in Python. It has been heavily inspired by a
similar project for Rust, powerpack.
It comes with a CLI that helps bootstrapping, maintaining and packaging the workflow.
Dependencies are vendored and packaged with the workflow so that they don't need to be installed into the system Python.
See the section on adding dependencies for details.
Documentation
The documentation is deployed to GitHub pages.
Installation
You can install directly from PyPI:
pip install pyfred-cli

Using the CLI
The CLI knows four commands: new, link, package, vendor.
See pyfred {new,vendor,link,package} -h for detailed help.
New
Bootstraps a new workflow with a single script filter and links it into Alfred.
It creates a new directory with the given name and copies a "Hello Alfred" workflow there.
The workflow can be used immediately by invoking Alfred with the specified keyword.
The following example creates a hello directory containing a workflow that can be triggered with the hi keyword. The
result of the selected action is copied to the clipboard.
pyfred new hello -k hi -b de.muffix.helloalfred --author=Muffix --description="Hello Alfred".

Link
Executed from a directory bootstrapped by this CLI, it links or relinks the workflow into Alfred.
pyfred link

Vendor
Downloads the dependencies listed in the requirements.txt file and vendors them into the workflow/vendored
directory. Doing this avoids having to install them into the system Python interpreter.
pyfred vendor

Package
Packages the workflow into a *.alfredworkflow file in the dist directory. The file contains the entire workflow and
all dependencies. It can be distributed and imported.
pyfred package

Debug output
The CLI will log debug output if the --debug flag is passed before the command.
Creating a workflow
The classes from the pyfred.model module represent the output expected by Alfred from a script filter.
pyfred.workflow provides a decorator for the entry point of a filter. It preprocesses the input and serialises the
response to stdout, where it is being picked up by the next input.
A minimal example for a script filter workflow looks like this:
from pyfred.model import Environment, OutputItem, ScriptFilterOutput
from pyfred.workflow import script_filter

@script_filter
def main(script_path: Path, args_from_alfred: list[str], env: Optional[Environment]) -> ScriptFilterOutput:
return ScriptFilterOutput(items=[OutputItem(title="Hello Alfred!")])

Adding dependencies
When running the workflow, Alfred will use the system Python interpreter to run the script. Third-party libraries are
not available in the interpreter unless explicitly installed. In order to not pollute the system Python, dependencies
can be vendored with the workflow using the pyfred vendor command. It is also automatically run with pyfred package.
If you add dependencies to your requirements.txt file, you need to run pyfred vendor to download them. You do not
need to prefix the import with vendored because the template adds that directory to the PYTHONPATH variable when the
workflow runs.
IDE setup
If you're using an IDE like PyCharm, you'll want to open the generated directory and set up the workflow subdirectory
as the content root. Additionally, you should add the workflow/vendored directory as source directory in the PyCharm
project settings. This helps it resolve the imports correctly.
Adding icons
You can add an icon for your workflow to the workflow directory in the generated skeleton.
The file name must be icon.png
You can assign individual icons to your output items. See the pyalfred.model.Icon class for more details.
Distribution through GitHub releases
The skeleton created by pyfred new comes with a GitHub action that creates a draft release whenever a tag starting
with v is pushed. To create a tag, run git tag v1.0.0 and push it with git push origin v1.0.0. When the action
has finished, go to the Releases page of your repository and publish the new release.
