# read-protobuf
Small library to read serialized protobuf(s) directly into Pandas Dataframe.
This is meant to be a simple shortcut to getting from serialized protobuf bytes / files directly to a dataframe.
>Note: This currently only supports basic proto3 features for Python 3. I have not yet tested it with proto2, though I believe that should work. I plan to expand the utility of this library with time and need.
## Install
Available via pip:
```bash
$ pip install read-protobuf
```
## Usage
Run the [demo-notebook](tests/demo.ipynb) for an interactive demo.
```python
import demo_pb2 # compiled protobuf message module
from read_protobuf import read_protobuf
MessageType = demo_pb2.MessageType() # instantiate a new message type
df = read_protobuf(b'\x00\x00', MessageType) # create a dataframe from serialized protobuf bytes
df = read_protobuf([b'\x00\x00', b'x00\x00'] MessageType) # read multiple protobuf bytes
df = read_protobuf('demo.pb', MessageType) # use file instead of bytes
df = read_protobuf(['demo.pb', 'demo2.pb'], MessageType) # read multiple files
# options
df = read_protobuf('demo.pb', MessageType, flatten=False) # don't flatten pb messages
df = read_protobuf('demo.pb', MessageType, prefix_nested=True) # prefix nested messages with parent keys (like pandas.io.json.json_normalize)
```
To compile a protobuf Message class from python, use:
```bash
$ protoc --python_out="." demo.proto
```
## Alternatives
#### protobuf-to-dict
https://github.com/benhodgson/protobuf-to-dict
This library was developed earlier to convert protobufs to JSON via a dict.
#### JSON
The google protobuf library comes with a utility to convert messages to JSON. Then the JSON objects could be loaded into pands via `pd.read_json()`.
```python
from google.protobuf.json_format import MessageToJson
```
In my brief tests, the `read_protobuf` package is about twice as fast as converting a protobuf to a dataframe using `MessageToJson`.
## Develop
Currently developed for Python 3 using the anaconda python distribution. To install a development version of the package, run from the root directory:
```bash
$ pip install -e .
```
- To install development dependencies, use pip on the `dev-requirements.txt` file:
```bash
$ pip install -r dev-requirements.txt
```
## Lint
Uses `pylint` to lint application.
```
$ pylint read_protobuf
```
Configuration options are specified in `.pylintrc`
## Test
Uses `pytest` to run unit tests. From the root of the repository, run:
```
$ pytest
$ pytest -k "TestRead::test_read_bytes" # specify test
```
Configuration options are specified in `setup.cfg`
## Code Coverage
We use `coverage` to monitor code coverage during tests. To record coverage while running tests, run:
```bash
$ coverage run -m pytest # watch files while testing
$ coverage report # will display coverage report
```
