Sorry, haven't been on for a couple of weeks. The plugin is dead simple,
and ONLY does commit, as handling push/pull would necessitate manual
intervention on conflicts, so I do that using a bash script instead.

The proper name is 'fava extension', and on any recent version of fava you
can find documentation about it on the Help page. It seems there's a recent
fava-plugins project to collect these[1].

My plugin looks like this:-

import os
import subprocess
from fava.ext import FavaExtensionBase
'''
Example hook for fava.

The hook add_transaction_git_commit will automatically add all files with
the
beancount suffix in fava's root folder and commit them with a message based
on
the transaction's narration, payee, and date.

To limit external dependencies, this uses the subprocess module (2.4+).
Please
read the documentation for that[1], especially if you're considering using
shell=True (probably a bad idea).

[1] - https://docs.python.org/2/library/subprocess.html
'''

class AutoCommit(FavaExtensionBase):
def _run(self, args):
cwd = os.path.dirname(self.ledger.beancount_file_path)
subprocess.call(args, cwd=cwd, stdout=subprocess.DEVNULL)

def after_write_source(self, path, _):
message = 'autocommit: file saved'
self._run(["git", "add", path])
self._run(["git", "commit", "-m", message])

def after_insert_metadata(self, *_):
message = 'autocommit: metadata added'
self._run(["git", "commit", "-am", message])

def after_insert_entry(self, entry):
message = 'autocommit:'
if entry.narration:
message += '"{}"'.format(entry.narration)
if entry.payee:
if message:
message += ' paid to "{}"'.format(entry.payee)
else:
message = 'Payment to "{}"'.format(entry.payee)
if message:
message += ' on {}'.format(entry.date)
else:
message += 'entry on {}'.format(entry.date)
self._run(["git", "commit", "-am", message])

I'm also planning a PR to extend fava's extensions capabilities[2] such
that they can modify the transactions themselves, but haven't had time to
get round to it (yet).

Re: (Eventual) native support for Windows?

I would like to share a successful example as a potential approach of
"native" Windows release of Beancount: 
https://github.com/borgbackup/borg/issues/440

BorgBackup is an excellent backup tool (try it out!) written in Python
and Cython. So compiling it in Windows is a headache, just like
Beancount. A contributor finally created an all-in-one Windows binary
installer for BorgBackup. The installation is self-contained and bundles
Cygwin, Python 3, and all the Python dependencies. It took ~100 MiB disk
space but it saves you from "polluting" your Windows with tons of
development tools.

I have been using the Windows BorgBackup release on my gaming PC for a
few months and it works well. You may consider creating a similar
Beancount Windows release as well.
