# fabsync
- Homepage: https://sr.ht/~psagers/fabsync/
- Source code: https://hg.sr.ht/~psagers/fabsync
- Documentation: https://fabsync.ignorare.net/
## Overview
This is a file-syncing tool for [Fabric][]. It's almost as straightforward to
use as rsync, but with some of the features that will be familiar from
deployment automation tools like Ansible.
Key points:
- Source files are kept in a simple directory tree, as if you were going to
rsync them.
- Metadata—such as ownership and permissions—is configured in TOML files
throughout the tree.
- Rendering functions can be configured to transform file contents. You can hook
these up to template engines or anything else.
- Paths and tags can be used to sync a subset of the file tree.
The most important thing to note is that this is a library, not a framework. It
does one simple thing, which you're welcome to integrate into your own
deployment scheme any way you like. For illustration purposes, here's a fragment
of a hypothetical `fabfile.py` that you might write:
```python
import io
from pathlib import Path
from typing import Any, Mapping
from fabric import Connection, task
import fabsync
import pystache
import tomli
def _mustache_renderer(conn: Connection) -> fabsync.Renderer:
try:
result = conn.get('/usr/local/etc/fabsync.toml', io.BytesIO())
except FileNotFoundError:
host = {}
else:
host = tomli.loads(result.local.getvalue().decode())
renderer = pystache.Renderer(escape=lambda s: s)
def render(path: Path, vars: Mapping[str, Any]) -> str:
with path.open('rt') as f:
return renderer.render(f.read(), host | vars)
return render
@task(iterable=['tag'], incrementable=['verbose'])
def sync(conn, subpath=None, tag=None, verbose=0):
root = fabsync.load('files', '/')
selector = fabsync.ItemSelector.new(subpath=subpath, tags=tag)
renderers = {'mustache': _mustache_renderer(conn)}
dry_run = conn['run']['dry']
for result in fabsync.isync(conn, root, selector, renderers, dry_run=dry_run):
print(f"{result.path}{' [modified]' if result.modified else ''}")
if verbose > 0 and result.diff:
print(result.diff.decode())
```
Of course you may also wish to save the results and use them to decide what
other actions to perform (e.g. restarting services).
Because we're just dealing with files, fabsync can offer a few other convenience
functions, including one that renders the source tree into human-readable rows.
If you rendered this with PrettyTable, it might look like this:
```
+-----------------------------------+------+-------+------------+----------+-------+--------+
| Path | User | Group | Mode | Renderer | Diff? | Tags |
+-----------------------------------+------+-------+------------+----------+-------+--------+
| /usr/ | | | | | | |
| /usr/local/ | | | | | | |
| /usr/local/etc/ | | | | | | |
| /usr/local/etc/mail/ | | | | | | mail |
| /usr/local/etc/mail/smtpd.conf | | | | | | mail |
| /usr/local/etc/rc.d/ | root | wheel | | | | |
| /usr/local/etc/rc.d/restic-server | root | wheel | -rwxr-xr-x | | | restic |
| /usr/local/etc/smb4.conf | | | | | | |
| /usr/local/etc/wireguard/ | | | drwx------ | | | wg |
| /usr/local/etc/wireguard/wg0.conf | | | -rw------- | mustache | | wg |
| /usr/local/utils/ | | | | | | |
+-----------------------------------+------+-------+------------+----------+-------+--------+
```

## Contributing
I wrote this for my own purposes and published it primarily to enforce the
discipline of comprehensive documentation and tests. It's deliberately narrow in
scope. New features are not out of the question, but mostly only those that
would be considerably more effort to implement externally.
Feel free to reach out with bug reports or suggestions. And note the Unlicense,
which means you can also just take the code and do what you like with it.
