# JSONvv
JSON value validator
## Overview
This is a simple JSON schema validator library. It was created for Camoufox to validate passed user configurations. Because I found it useful for other projects, I decided to extract it into a separate library.
JSONvv's syntax parser is written in pure Python. It does not rely on any dependencies.
### Example
<table>
<tr>
<th width="50%">Configuration</th>
<th width="50%">Validator</th>
</tr>
<tr>
<td width="50%">
```python
config = {
"username": "johndoe",
"email": "johndoe@example.com",
"age": 30,
"chat": "Hello world!",
"preferences": {
"notifications": True,
"theme": "dark"
},
"allowed_commands": [
"/help", "/time", "/weather"
],
"location": [40.7128, -74.0060],
"hobbies": [
{
"name": "Traveling",
"cities": ["Paris", "London"]
},
{
"name": "reading",
"hours": {
"Sunday": 2,
"Monday": 3,
}
}
]
}
```
</td>
<td width="50%">
```python
validator = {
"username": "str", # Basic username
"email": "str[/\S+@\S+\.\S+/]", # Validate emails
"age": "int[>=18]", # Age must be 18 or older
"chat": "str | nil", # Optional chat message
"preferences": {
"notifications": "bool",
"theme": "str[light, dark] | nil", # Optional theme
},
# Commands must start with "/", but not contain "sudo"
"allowed_commands": "array[str[/^//] - str[/sudo/]]",
# Validate coordinate ranges
"location": "tuple[double[-90 - 90], double[-180 - 180]]",
# Handle an array of hobby types
"hobbies": "array[@traveling | @other, >=1]",
"@traveling": {
# Require 1 or more cities/countries iff name is "Traveling"
"*name,type": "str[Traveling]",
"*cities,countries": "array[str[A-Za-z*], >=1]",
},
"@other": {
"name,type": "str - str[Traveling]", # Non-traveling types
# If hour(s) is specified, require days have >0 hours
"/hours?/": {
"*/day$/": "int[>0]"
}
}
}
```
</td>
</tr>
</table>
<hr width=50>
Then, validate the configuration like this:
```python
from jsonvv import JsonValidator, JvvRuntimeException
val = JsonValidator(validator)
try:
val.validate(config)
except JvvRuntimeException as exc:
print("Failed:", exc)
else:
print('Config is valid!')
```

## Keys Syntax
Dictionary keys can be specified in several possible ways:
- `"key": "type"`
- `"key1,key2,key3": "type"`
- `"/key\d+/": "type"`
- `"*required_key": "type"`
### Regex patterns
To use regex in a key, wrap it in `/ ... /`.
**Syntax:**
```python
"/key\d+/": "type"
```
### Lists of possible values
To specify a list of keys, use a comma-separated string.
**Syntax:**
```python
"key1,key2,key3": "type"
"/k[ey]{2}1/,key2": "type"
```
To escape a comma, use `!`.
### Required fields (`*`)
Fields marked with `*` are required. The validation will fail without them.
**Syntax:**
```python
"*key1": "type"
"*/key\d+/": "type"
```
### Grouping keys (`$`)
Fields that end with `$group_name` are grouped together. If one of the keys is set, all of the keys in the group must also be set as well.
**Syntax:**
```python
"isEnabled$group1": "bool"
"value$group1": "int[>0]"
```
This will require both `value` is set if and only if `isEnabled` is set.
Multiple `$` can be used to create more complex group dependencies.
---
## Supported Types
### String (`str`)
Represents a string value. Optionally, you can specify a regex pattern that the string must match.
**Syntax:**
- Basic string: `"str"`
- With regex pattern: `"str[regex_pattern]"`
- The escape character for regex is `\`, and for commas is `_`.
**Arguments:**
- `regex_pattern`: A regular expression that the string must match. If not specified, any string is accepted.
**Examples:**
1. Basic string:
```python
"username": "str"
```
Accepts any string value for the key `username`.
2. String with regex pattern:
```python
"fullname": "str[/[A-Z][a-z]+ [A-Z][a-z]+/]"
```
Accepts a string that matches the pattern of a first and last name starting with uppercase letters.
### Integer (`int`)
Represents an integer value. You can specify conditions like exact values, ranges, and inequalities.
**Syntax:**
- Basic integer: `"int"`
- With conditions: `"int[conditions]"`
**Arguments:**
- `conditions`: A comma-separated list of conditions.
**Condition Operators:**
- `==`: Equal to a specific value.
- `>=`: Greater than or equal to a value.
- `<=`: Less than or equal to a value.
- `>`: Greater than a value.
- `<`: Less than a value.
- `range`: A range between two values (inclusive).
**Examples:**
1. Basic integer:
```python
"age": "int"
```
Accepts any integer value for the key `age`.
2. Integer with conditions:
```python
"userage": "int[>=0, <=120]"
```
Accepts integer values between 0 and 120 inclusive.
3. Specific values and ranges
```python
"rating": "int[1-5]"
"rating": "int[1,2,3,4-5]"
```
Accepts integer values 1, 2, 3, 4, or 5.
4. Ranges with negative numbers:
```python
"rating": "int[-100 - -90]"
```
Accepts integer values from -100 to -90.
### Double (`double`)
Represents a floating-point number. Supports the same conditions as integers.
**Syntax:**
- Basic double: `"double"`
- With conditions: `"double[conditions]"`
**Arguments:**
- `conditions`: A comma-separated list of conditions.
**Examples:**
1. Basic double:
```python
"price": "double"
```
Accepts any floating-point number for the key `price`.
2. Double with conditions:
```python
"percentage": "double[>=0.0,<=100.0]"
```
Accepts double values between 0.0 and 100.0 inclusive.
### Boolean (`bool`)
Represents a boolean value (`True` or `False`).
**Syntax:**
```python
"isActive": "bool"
```
Accepts a boolean value for the key `isActive`.
### Array (`array`)
Represents a list of elements of a specified type. You can specify conditions on the length of the array.
**Syntax:**
- Basic array: `"array[element_type]"`
- With length conditions: `"array[element_type,length_conditions]"`
**Arguments:**
- `element_type`: The type of the elements in the array.
- `length_conditions`: Conditions on the array length (same as integer conditions).
**Examples:**
1. Basic array:
```python
"tags": "array[str]"
```
Accepts a list of strings for the key `tags`.
2. Array with length conditions:
```python
"scores": "array[int[>=0,<=100],>=1,<=5]"
```
Accepts a list of 1 to 5 integers between 0 and 100 inclusive.
3. Fixed-length array:
```python
"coordinates": "array[double, 2]"
```
Accepts a list of exactly 2 double values.
4. More complex restraints:
```python
"coordinates": "array[array[int[>0]] - tuple[1, 1]], 2]"
```
### Tuple (`tuple`)
Represents a fixed-size sequence of elements of specified types.
**Syntax:**
```python
"tuple[element_type1, element_type2]"
```
**Arguments:**
- `element_typeN`: The type of the Nth element in the tuple.
**Examples:**
1. Basic tuple:
```python
"point": "tuple[int, int]"
```
Accepts a tuple or list of two integers.
2. Tuple with mixed types:
```python
"userInfo": "tuple[str, int, bool]"
```
Accepts a tuple of a string, an integer, and a boolean.
### Nested Dictionaries
Represents a nested dictionary structure. Dictionaries are defined using Python's dictionary syntax `{}` in the type definitions.
**Syntax:**
```python
"settings": {
"volume": "int[>=0,<=100]",
"brightness": "int[>=0,<=100]",
"mode": "str"
}
```
**Usage:**
- Define the expected keys and their types within the dictionary.
- You can use all the supported types for the values.
**Examples:**
1. Nested dictionary:
```python
"user": {
"name": "str",
"age": "int[>=0]",
"preferences": {
"theme": "str",
"notifications": "bool"
}
}
```
Defines a nested dictionary structure for the key `user`.
### Nil (`nil`)
Represents a `None` value.
**Syntax:**
```python
"optionalValue": "int | nil"
```
**Usage:**
- Use `nil` to allow a value to be `None`.
- Often used with union types to specify optional values.
### Any (`any`)
Represents any value.
**Syntax:**
```python
"metadata": "any"
```
**Usage:**
- Use `any` when any value is acceptable.
- Useful for keys where the value is not constrained.
### Type References (`@`)
Allows you to define reusable types and reference them.
**Syntax:**
- Define a named type:
```python
"@typeName": "type_definition"
```
- Reference a named type:
```python
"key": "@typeName"
```
**Examples:**
1. Defining and using a named type:
```python
"@positiveInt": "int[>0]"
"userId": "@positiveInt"
```
Defines a reusable type `@positiveInt` and uses it for the key `userId`.
---
## Advanced Features
### Subtracting Domains (`-`)
Allows you to specify that a value should not match a certain type or condition.
**Syntax:**
```python
"typeA - typeB"
```
**Usage:**
- The value must match `typeA` but not `typeB`.
**Examples:**
1. Excluding certain strings:
```python
"message": "str - str[.*error.*]"
```
Accepts any string that does not match the regex pattern `.*error.*`.
2. Excluding a range of numbers:
```python
"score": "int[0-100] - int[>=90]"
```
Accepts integers between 0 and 100, excluding values greater than or equal to 90.
3. Excluding multiple types:
```python
"score": "int[>0,<100] - int[>90] - int[<10]"
# Union, then subtraction:
"score": "int[>0,<100] - int[>90] | int[<10]"
"score": "int[>0,<100] - (int[>90] | int[<10])" # same thing
# Use parenthesis to run subtraction first
"score": "int[>0,<50] | (int[<100] - int[<10])"
"score": "(int[<100] - int[<10]) | int[>0,<50]"
```
**Note**: Union is handled before subtraction.
4. Allowing all but a specific value:
```python
"specialNumber": "any - int[0]"
```
### Union Types (`|`)
Allows you to specify that a value can be one of multiple types.
**Syntax:**
```python
"typeA | typeB | typeC"
```
**Usage:**
- The value must match at least one of the specified types.
**Examples:**
1. Multiple possible types:
```python
"data": "int | str | bool"
```
Accepts an integer, string, or boolean value for the key `data`.
2. Combining with arrays:
```python
"mixedList": "array[int | str]"
```
Accepts a list of integers or strings.
### Conditional Ranges and Values
Specifies conditions that values must satisfy, including ranges and specific values.
**Syntax:**
- Greater than: `">value"`
- Less than: `"<value"`
- Greater than or equal to: `">=value"`
- Less than or equal to: `"<="value"`
- Range: `"start-end"`
- Specific values: `"value1,value2,value3"`
**Examples:**
1. Integer conditions:
```python
"level": "int[>=1,<=10]"
```
Accepts integers from 1 to 10 inclusive.
2. Double with range:
```python
"latitude": "double[-90.0 - 90.0]"
```
Accepts doubles between -90.0 and 90.0 inclusive.
3. Specific values:
```python
"status": "int[1,2,3]"
```
Accepts integers that are either 1, 2, or 3.
