I figured this out. Turns out Boost Python was my unknown-unknown here.
There still is no turnkey way to work with ledger in Python, but it is
possible. This is what I did
- Clone the ledger repository locally *gh repo clone ledger/ledger*
- *cd ledger*
- *mkdir build* — this collects all the build artefacts if present; it's
a cleaner way than building in the repository root
- run *./acprep --python dependencies* to ensure ledger dependencies are
installed
- if this does not automatically install *boost-python*, ensure you
have it
- run *./acprep --compiler=c++ --python --ninja*
- I'm on a mac, hence *c++* because of some libraries from Apple
- I kept the *--python* tag cos that's the end goal here
- and *--ninja* is a sweet quiet incremental make
- Copy the built library into your Python project — *cp
build/ledger/debug/ledger.so path/to/your/python-project*`
With this done, you can then *import** ledger* and follow along with
everything in the Extending with Python
<https://ledger-cli.org/doc/ledger3.html#Extending-with-Python> section of
the documentation. One way to test this is to copy *python/demo.py* to the
build directory and run it. It should run fine.
Do I wish there was an easier way to do this, so we can unlock the
innovation of smart Python folks looking to build extensions for ledger and
ending up defaulting to other tools? Yes, I do; but I lack the python-fu
and c++-fu to get this done — please help contribute if you can.
