Aer (/ɛə/ from Latin: aer, meaning air) is a lightweight, OpenSource, general-purpose, object-oriented scripting programming language suited also for web development as well as embedded environments. It implements a highly-efficient bytecode compiler and a virtual machine. The term Aer is used interchangeably with AerScript. Its syntax draws upon C#, Java and PHP.
Aer is the ideal language interpreter for writing enhanced web applications like blog, CMS, search engine, etc. or embedded solutions with dynamic web interfaces like routers, set-top-boxes, or smart home solutions. Aer Interpreter is based on PH7 Engine and thus it is 100% hand-coded, written in pure C software, that compiles unmodified and runs on any platform including restricted embedded device with a C compiler.
The core syntax of Aer language is similar to that of other C-style languages such as C++, C#, Java or PHP. In particular:
- Semicolons are used to denote the end of a statement.
- Curly brackets are used to group statements. Statements are commonly grouped into methods (functions), methods into classes, and classes into namespaces.
- Variables are assigned using an equals sign, but compared using two consecutive equals signs.
- Square brackets are used with arrays, both to declare them and to get a value at a given index in one of them.
Full Aer Specification can be found on the Wiki Pages.
AerScript - Modern PHP
Despite, that Aer syntax draws among others upon PHP, it is not fully compatible with it. Aer is a modern, pure Object-Oriented Language. The distinctive features and powerful extensions to the PHP programming language are:
- Strict, full OOP,
- Method overloading,
- Strict, full type hinting,
- Introducing comma expressions,
- Improved operator precedences,
- 64-bit integer arithmetic for all platforms,
- Smart exception mechanism,
- Native UTF-8 support,
- Built-in standard library and extensions support,
- Garbage Collected via Advanced Reference Counting,
- Correct and consistent implementation of the ternary operator,
- Consistent Boolean evaluation,
- Introducing the $_HEADER superglobal array which holds all HTTP MIME headers.
64-Bit Integer Arithmetic For All Platforms
Unless most scripting and programming languages, Aer have standardized the size of an integer and is always stored in 8 bytes regardless of the host environment. Because there is no cross-platform way to specify 64-bit integer types Aer includes typedefs for 64-bit signed integers. Thanks to that, integers can store values between -9223372036854775808 and +9223372036854775807 inclusive, both on 32-bit and on 64-bit host OS.
Aer and the PH7 Engine are OpenSource projects.
