Syntax

BayLang uses C-like syntax.

Program example

namespace Main;

class App
{
    static int main()
    {
        print("Hello world");
        return 0;
    }
}

Component example:

<class name="App.Components.IndexPage.IndexPage">

<style>
.index_page{
    padding: 5px;
}
</style>

<template>
    <div class="index_page">
        <h1>Index page</h1>
    </div>
</template>

</class>

Variable types

Scalar types:

• int - integer
• double - double precision floating point number
• bool - boolean type
• string - string

Objects:

• Vector - vector
• Map - Dictionary where keys are strings. Converting object hash function to string needs to be done manually or with the help of additional libraries.
• Date, DateTime - Classes for working with date and time

Standard classes

• rlt - Runtime library with common functions
• rs - Class for working with strings
• re - Regular expressions
• fs - Class for working with file system

Main classes:

• BaseModel - basic model implementation
• BaseObject - base object from which most classes inherit
• BaseProvider - provider
• Chain, ChainAsync - call chains
• Component - base component
• Context - main class implementing application context
• Curl - Sending HTTP requests
• File - File object
• Method - Calling functions by name
• Money - Class for working with money
• Reference - Reference
• Serializer - Object serialization
• VirtualDom - Virtual DOM

Variables

In BayLang it is customary to use variables in snake_case style: lowercase and using underscores. This is needed to visually distinguish variables from methods. Methods on the contrary use CamelCase.

Example:

int count = 0;
string message = "Hello";
bool is_active = false;
Vector items = [];
Map map = {};

Template example:

<template>
    %set int count = 0;
    %set string message = "Hello";
    %set bool is_active = false;
    %set Vector items = [];
    %set Map map = {};
</template>

Conditions

Example:

if (a > b)
{
    print ("A is greater than B");
}
else
{
    print ("A is less than or equal to B");
}

Conditions in templates:

<template>
    %if (a > b)
    {
        <span>A is greater than B</span>
    }
    %else
    {
        <span>A is less than or equal to B</span>
    }
</template>

Loops

int sum(Vector items)
{
    int result = 0;
    for (int i=0; i<items.count(); i++)
    {
        sum += items.get(i);
    }
    return result;
}

Loop in template:

<template>
    <div class="items">
    %for (int i=0; i<this.items.count(); i++)
    {
        <div class="item">{{ this.items.get(i) }}</div>
    }
    </div>
</template>
