zserio 2.18.1

Zserio runtime with compiler.

Zserio PyPi package contains Zserio compiler and Zserio Python runtime. Zserio is serialization framework available at GitHub.

Installation

To install Zserio compiler together with Zserio Python runtime, just run

pip install zserio

Usage from command line

Consider the following zserio schema which is stored to the source appl.zs:

package appl;

struct TestStructure
{
    int32 value;
};

To compile the schema by compiler and generate Python sources to the directory gen, you can run Zserio compiler directly from command line by the following command:

zserio appl.zs -python gen

Then, if you run the python by the command

PYTHONPATH="gen" python

you will be able to use the generated Python sources by the following python commands

import appl.api as api
test_structure = api.TestStructure()

Usage from Python

Consider the following zserio schema which is stored to the source appl.zs:

package appl;

struct TestStructure
{
    int32 value;
};

To compile the schema by compiler and generate Python sources to the directory gen, you can run the following python commands:

import zserio
api = zserio.generate("appl.zs", gen_dir = "gen")
test_structure = api.TestStructure()

For convenience, the method generate returns imported API for generated top level package.

Alternatively, you can run zserio compiler directly by the following python commands:

import sys
import importlib
import zserio
completed_process = zserio.run_compiler(["appl.zs", "-python", "gen"])
if completed_process.returncode == 0:
    sys.path.append("gen")
    api = importlib.import_module("appl.api")
    test_structure = api.TestStructure()
