1C:Enterprise programming language
1C:Enterprise script is a high-level programming language created by 1C company. It is a fourth-generation programming language[1] allowing to quickly design and customize business applications as part of the rapid application development platform 1C:Enterprise.
1C:Enterprise script is an object-based (but not object-oriented) language with dynamic typing.[2][3]
1C:Enterprise script was designed as a programming language intended for coding of business algorithms. 1C:Enterprise script is a part of 1C:Enterprise technological platform which implements Metadata-Driven Application Design and Development[4] approach that allows usage of low-code (low-code paradigm).[5]
1C:Enterprise script supports objects. There is number of integrated object types (Catalogs, Documents, Business Processes etc.) that implement pre-defined functionality.[6] Developers inherit their objects from integrated object types but further inheritance (from developers’ objects) is not supported.
A similar approach to inheritance is used in prototype-based programming.
1C:Enterprise script has much in common with other programming languages, such as JavaScript or Python, but it is not a replica of any of these languages.[3]
Examples of programming languages syntax
| Language Name | Example of syntax |
|---|---|
| 1C:Enterprise script | Procedure HelloWorld()
Message("Hello World"); EndProcedure |
| JavaScript | <script language = 'javascript'>
document.write("Hello World"); </script> |
| Java | class HelloWorld {
public static void main(String[] args) { System.out.println("Hello World!"); } } |
| C# | using System;
class Program { public static void Main(string[] args) { Console.WriteLine("Hello, world!"); } } |
| Python 3.x | print("Hello, world!") |
| SQL | CREATE TABLE message (text char(15));
INSERT INTO message (text) VALUES ('Hello, World!'); SELECT text FROM message; DROP TABLE message; |
| Visual Basic .NET | Imports System
Public Module modmain Sub Main() Console.WriteLine ("Hello World using Visual Basic!") End Sub End Module |
| ABAP | PROGRAM zhello_world.
START-OF-SELECTION. WRITE 'Hello, World!'. |
| APEX | @isTest
private class HelloWorldTest { @isTest static void hello() { HelloWorld hello_world = new HelloWorld(); String result = hello_world.hello(); } } |
Developers create applied solutions based on 1C:Enterprise mostly in a built-in visual editor with an ability to add functionality written in 1C:Enterprise script. This includes the creation of objects and specifying their properties, presentation forms, objects’ interrelations, and so on.
1C:Enterprise script usually only required for describing special, nonstandard behavior of applied solution objects and custom data processing algorithms (say, tax calculation).[7]
1C:Enterprise script language is intended for describing business logic, and 1C:Enterprise script module calls are event-driven. Modules are executed when specific events occur in the applied solution.[8][7]
Development environment
Development in 1C:Enterprise script can be done either in Designer ( proprietary development environment) or in 1C:Enterprise Development Tools[9] (development environment based on the open Eclipse platform). Both tools support debugging, profiling, intellisense, syntax highlighting, code refactoring tools etc.
There is syntax highlighting support for 1C:Enterprise script source code implemented on GitHub.[10][11]
Language features
1C:Enterprise script modules are compiled into bytecode that is executed by 1C:Enterprise virtual machine.[3] There are implementations of 1C:Enterprise virtual machine for different OS (Windows, Linux, macOS) and for browsers (implemented in JavaScript).[5]
Application's code can be executed on the server-side as well as on client-side.[5]
Weak typing: a variable type is defined by the stored value and can change over time.[3]
