Asynchronous Programming

Creating complex asynchronous behaviors is now easier with VAST's best-in-class futures/promises framework, plus asynchronous streams and zones, inspired by similar functionality from the Dart programming language.

Multi-CPU Capable with FFI & OsProcess

Whether using native threads, or OS processes, take advantage of multiple processors by using VAST's multi-threaded foreign function interface (FFI) or our OsProcess framework.

Advanced Unicode Capabilities

VAST brings a truly ergonomic Unicode experience to Smalltalk. We went beyond "basic" Unicode support, and instead designed an advanced implementation that focused on "Unicode Correctness" and performance.

Development Tools icon

Development Tools

Advanced Code Editing

A code editor for true polyglots supporting code highlighting in 25+ languages including C, C++, Python®, JavaScript®, Swift™, Go™, Rust™, etc. with fully customizable color theming and linting.

Development Browsers

Best-in-class debuggers, code management browsers, inspectors, a performance monitor, code reporting tools, unit testing browsers, and linters.

WYSIWYG GUI Builders

VAST has two GUI builders to help visually build your application: WindowBuilder Pro™ and Abt Parts. Choose whichever one works best for your workflow.

Code Completion Tools

As you're coding, these tools contextually analyze your code and provide the most appropriate suggestions.
VAST Environments icons

VAST Environments

Smalltalk image manager and launcher to help efficiently handle multi-image workflows in VAST.

Real-time Code Analysis

Monitors code as you type to provide hints about errors, warnings, and optimization opportunities.

Live Refactoring Tools

Realtime visual tooling helps expedite the restructuring of your code for better maintainability.
User Interface & Visuals icon

User Interface & Visuals

Hi DPI

Hi DPI support in Windows®-based environments provides crisp graphics on modern device screens.

Native Widgets

Native widgets provide a familiar look-and-feel for Windows and Linux® without the need to make platform dependent code.

Emulated Widgets

Most needs can be satisfied with native widgets, but emulated widgets help fill in the gaps and allow you to completely take control of the look and feel of your user interface.

Graphic Acceleration

DirectWrite and GPU acceleration are utilized within the editors on Windows.
Communications & Web Dev icon

Communications & Web Dev

Web Services Tools

A self-contained, modular framework for accessing and hosting Web Services with tools for creating and deploying them.

Server Smalltalk (SST)

SST is a flexible communications framework that is the foundation of many VAST protocol implementations including distributed garbage collection, logical processes, web services, HTTP, SMTP, and IMAP.

Integrated Web Technology

Inclusion of the Seaside web framework, REST, HTTPS, jQuery, AJAX, and several other web development technologies and tools will get your web project off the ground quickly.

Network Protocol Support

Powerful HTTP, IMAP, SMTP, FTP/FTPS, IBM MQ series, and LDAP clients are all included for superior connectivity with a powerful sockets API including full support for TCP/IP V4/V6 protocols.

External Interface Support

Support for JSON, XML, CSV, COM (OLE, ACTIVEX), and STON (Smalltalk Object Notation). STON provides a lightweight, text-based object interchange in JSON format.

Streamed HTTP Retrieval

Using our asynchronous streams functionality, retrieve large pieces of streamed HTTP content, and asynchronously process these large files in smaller pieces for improved efficiency.
Databases icon

Databases

Relational DB Support

Use Oracle, DB2, PostgreSQL, SQLite database drivers (as well as ODBC) that take advantage of RDBMS (Relational Database Management Systems). 

Object Relational Mapping

Combine relational databases with our ORM (Object Relational Mapper): GLORP. 


Object-Oriented DB Support

Match the purely object-oriented approach of Smalltalk with a similar database structure. VAST is compatible with object-oriented databases, like GemStone/S.
Security icon

Security

Object Oriented Wrapper

As part of our OpenSSL® 3.0 implementation, VAST has an high-level object oriented wrapper around OpenSSL that's easy to use, and backward compatible with previous versions of 0.9.8 through 1.1.x.  

SSL/TLS Modules

VAST incorporates Secure Sockets Layer (SSL) and TLS v1.3 technology which provide industry-standard security over computer networks.

FIPS Module

Access OpenSSL's collection of a compliant algorithms used meet the FIPS 140 standard.
(Anticipated acceptance of OpenSSL's compliance by NIST by Q3/Q4 2022.)

X509 Support

VAST provides the ability to identify and secure internet communications with public key certificates using the X509 standard.

Message Digests

Access a wide range of cryptographic hash functions designed to protect the integrity of data, like the SHA family, SHAKE, and BLAKE2.

Message Authentication Codes

In addition to data integrity, like message digests, MAC also provide authentication. VAST supports message authentication codes like GMAC, KMAC, Poly1305, and Siphash.

Ciphers

VAST supports authenticated symmetric encryption, and various public key cryptography algorithms to encrypt and decrypt sensitive data.

Key Derivation

Improve security by deriving new secure keys from weaker plain text sources. Key derivation is frequently used in password storage and securing. Algorithms like Scrypt, PBKDF2, and HKDF are available.

Secure Memory Arenas

Use special, guarded sections of memory to help obscure and protect sensitive key material, now for both Windows and Linux with OpenSSL 3.0.

Secure RNG

A cryptographically strong random number generator using native OS capability is now available that has a high entropy.
Version Control icon

Version Control

ENVY Version Control

Unmatched version control. Store and compare all software components down to the method level.

Deployment

Cross Platform Development

XD Server Workbench is a cross-development environment used in developing distributed processing, web hosting, and other server applications. Target deployment environments include all VAST development platforms.

Packager

VAST's packager creates runtime images composed of only the necessary classes which results in a stripped down runtime image that can be less than 1MB.

Dependency Analysis Tools
