cheek 0.0.1

Command classes

The scripting command classes are implemented in the cheek.commands submodule as subclasses of cheek.commands.Command. These use pydantic to express their arguments. NB: we automatically generate these classes based on the output of Audacity’s GetInfo command. See below for more details.

At the time of writing, not all Audacity scripting commands are fully implemented. In particular, those which require parameters are not all done. Those without parameters are generally complete, though there may be bugs or gaps.

Basic programmatic use of a command is something like this:

from cheek.commands import AddLabel, SetLabel, do

do(
    AddLabel(),
    SetLabel(Label=0, Text="Label text", Start=123.456)
)

From the command line that might look like this:

cheek AddLabel
cheek SetLabel --Label 0 --Text "Label text" --Start 123.456

Tests

There are a few tests, though we’re very, very far from comprehensive. Really, since real testing would require determing that Audacity was doing the right thing, it’s probably not practical to really test this too fully. But if you’ve got ideas about testing, we could merge them in.

Re-generating the Command subclasses

We can use the output from the scripting command “GetInfo” to regenerate all of the Command subclasses. Right now this is a bit rough, but here’s what to do.

First, execute “GetInfo(‘Commands’, ‘JSON’)” and capture the output. You can do this with cheek itself, or pyaudacity, or whatever. The JSON you get is likely to be invalid at first, so you’ll need to clean it up. It should be clear how to do this.

Save this cleaned-up JSON to a file, e.g. “commands.json”. Then run:

python -m cheek.extract commands.json > src/cheek/commands.py

That should do it. You may want to run this generated Python through a formatter, though it should be valid Python as-is. Commit the new commands.py to git and you’ll have an updated command set. Copyright (c) 2024 Austin Bingham
