cosmos-proto 0.0.0

The Python Protobuf implementation for Cosmos SDK chains

Python implementation for cosmos.proto

Currently, this repo contains generated python files for Terra 2 and Osmosis Blockchains supported Modules.

Setup

1. Create virtual environment

$ python3 -m venv env
$ source env/bin/activate

2. Install poetry

$ pip install poetry

3. Install packages,

$ pip install poetry
$ poetry install

If you encounter "version solving failed." error, try poetry add <package_name>, followed by poetry lock and then poetry install

Generating python files for new proto files

We use betterproto[compiler] for generating python code from proto files, and it is party a manual process. Here are a few pointers to help you through the process -

• cd into each module and make sure all *.proto files are in one place.
• For each .proto file, check the import paths and update them if needed.
• Once the paths are corrected, use the following command to generate python files.

$ protoc -I . --python_betterproto_out=<OUTPUT DIR NAME> <PROTO FILE NAMES>

For eq - protoc -I . --python_betterproto_out=py genesis.proto query.proto gov.proto feetoken.proto

To install betterproto[compiler], use -

pip install "betterproto[compiler]"
