Overview

Validr

travis-ci codecov

A simple, fast, extensible python library for data validation.

  • Simple and readable schema
  • 10X faster than jsonschema, 40X faster than schematics
  • Can validate and serialize any object
  • Easy to create custom validators
  • Accurate and friendly error messages

简单,快速,可拓展的数据校验库。

  • 简洁,易读的 Schema
  • jsonschema 快 10 倍,比 schematics 快 40 倍
  • 能够校验&序列化任意类型对象
  • 易于拓展自定义校验器
  • 准确友好的错误提示

Overview

from validr import T, modelclass, asdict

@modelclass
class Model:
    """Base Model"""

class Person(Model):
    name=T.str.maxlen(16).desc('at most 16 chars')
    website=T.url.optional.desc('website is optional')

guyskk = Person(name='guyskk', website='https://github.com/guyskk')
print(asdict(guyskk))

Install

Note: Only support Python 3.5+

pip install validr

When you have c compiler in your system, validr will be c speedup mode. Otherwise validr will fallback to pure python mode.

To force c speedup mode:

VALIDR_SETUP_MODE=c pip install validr

To force pure python mode:

VALIDR_SETUP_MODE=py pip install validr

Develop

Validr is implemented by Cython since v0.14.0, it's 5X faster than pure Python implemented.

setup:

It's better to use virtualenv or similar tools to create isolated Python environment for develop.

After that, install dependencys:

./bootstrap.sh

build, test and benchmark:

inv build
inv test
inv benchmark
