What is an ST file?

An ST file contains source code written in the Smalltalk programming language. For example, it may contain a Smalltalk expression or script. Developers create ST files while writing Smalltalk programs.

Smalltalk is an object-oriented programming language that has influenced many other object-oriented programming languages. It has many variants, including Smalltalk-80, GNU Smalltalk, OpenSmalltalk, Squeak, and Dolphin Smalltalk.

Developers creating Smalltalk programs save the source code they've written as ST files. At runtime, the Smalltalk compiler compiles the code ST files contain to bytecode, which is typically interpreted by a Smalltalk virtual machine.

How to open an ST file

You can open an ST file with Microsoft Visual Studio Code (multiplatform) or any other text editor. Doing so will allow you to view and/or edit the Smalltalk source code your ST file contains.
