## Overview
**JSON Validator** is a feature-rich Python library designed to elevate the validation of JSON documents by offering an extensive schema-based validation system. It empowers developers to define custom schemas, providing fine-grained control over the structure, data types, and constraints of their JSON data.
## Key Features
### 1. Schema Definition
Define a schema for your JSON documents, specifying keys, data types, and constraints. The schema acts as a blueprint for validation.
### 2. Flexible Data Type Validation
Control the data types of each key in your JSON document. Enforce strict typing or allow flexibility based on your requirements.
### 3. Key Presence Validation
Detect and handle invalid keys in your JSON document that are not defined in the schema, ensuring data integrity.
### 4. Required and Optional Fields
Designate which fields are required and which are optional, guiding users in creating valid JSON documents.
### 5. Child Value Bypass
Allow bypassing the validation of child values, providing flexibility when certain sections of the JSON document don't require strict validation.
### 6. Value Bindings
Support value bindings to establish relationships between different parts of the JSON document, enhancing the expressiveness of your schemas.
### 7. Regular Expression Bindings
Support regular expression bindings for precise validation of values..
### 8. String Value Constraints
Control the minimum and maximum length of string values, applying constraints to ensure data meets specific length requirements.
### 9. Numeric Value Constraints
Define minimum and maximum values for integer and float types, allowing precise control over the numeric range of your data.
### 10. Case Constraints
Apply case constraints to string types, specifying whether they should be in lower, upper, or mixed case.
### 11. Spacing in String Values
Optionally allow spacing in string data types, enhancing readability in scenarios where formatted text is essential.
### 12. Custom Extension Library
Extend the functionality of the library by creating custom extensions, tailoring the validation process to your unique needs.
### Installation
```commandline
pip install jsvl -U
```
### Command line guide

### How to use
**Command line**
Validate a single json document.
```commandline
~$ jsvl -s /path/to/schema.json -d /path/to/document.json
```
Validate a single json document with URL.
```commandline
~$ jsvl -s http://www.yourdomain.com/schema.json -d /path/to/document.json
```
Validate multiple documents with a single schema.
```commandline
~$ jsvl -s /path/to/schema.json -d /path/to/documents/
```
Validate multiple documents with multiple schema.
```commandline
~$ jsvl -s /path/to/schema/ -d /path/to/documents/
```
Disable informative tags from the output.
```commandline
~$ jsvl -s path/to/schema.json -d /path/to/document.json --disable-tags
```
Remove formatting from the output.
```commandline
~$ jsvl -s path/to/schema.json -d /path/to/document.json --plain-output
```
### Use in Project:
Import **validate** function from **jsvl.core.validator** module and validate the document with multiple options.
```python
from jsvl.core.validator import validate
# schema json
schema = "http://www.youdomain.com/schema.json" or "path/to/schema.json" or "path/to/all_schema_dir/" or {}
# document json
document = "path/to/document.json" or "path/to/all_documents_dir/" or {} or []
# perform validation
result = validate(schema, document)
```
### Control Configs:
```python
import jsvl.config as cfg
from jsvl.utils.util import reserved_key
# change schema file postfix default is _schema
cfg.configs[cfg.schema_file_postfix] = "_schema"
# disable the output tags from logs
cfg.configs[cfg.enable_output_tags] = False
# remove the formatting from logs
cfg.configs[cfg.formatted_output] = False
# disable all the logs
cfg.configs[cfg.enable_output_logs] = True
# show the validation class name with logs
cfg.configs[cfg.enable_validation_source] = True
# disable the allow_space globally
cfg.configs[cfg.allow_space] = True
# set the minimum length globally, default is 0.
cfg.configs[cfg.min_length] = 0
# set the maximum length globally, default is None.
cfg.configs[cfg.max_length] = 1000
# set the minimum value globally, default is 0.
cfg.configs[cfg.min_value] = 0
# set the maximum value globally, default is None.
cfg.configs[cfg.max_value] = 1000
# set the text constraints globally, default is None.
cfg.configs[cfg.case] = reserved_key.upper
```
### Register Custom Validation Filters:
You can register two types of validation filter.
1. **Schema Validation**
```python
from jsvl.validations.schema_validations import schema_validation_set, SchemaValidation
# creating custom validation class for schema validation
class CustomSchemaValidation(SchemaValidation):
def validate(self, key, schema, path):
pass
# register validation in schema validation set
schema_validation_set.add(CustomSchemaValidation())
```
2. **Document Validation**
```python
from jsvl.validations.doc_validations import doc_validation_set, DocValidation
# creating custom validation class for document validation
class CustomDocValidation(DocValidation):
def validate(self, key, schema, doc, path, index, doc_is_dynamic):
pass
# register validation in document validation set
doc_validation_set.add(CustomDocValidation())
```
