Running ActionScript in Sublime Text: A Developer's Guide
Sublime Text is a popular code editor known for its speed, flexibility, and extensive customization options. While it doesn't natively support ActionScript compilation, with the right tools and configurations, you can efficiently develop and run ActionScript projects within Sublime Text.
The Challenge: ActionScript Execution
ActionScript, a scripting language used primarily for Flash and Flex development, requires a compiler to translate its code into bytecode, which can then be run by the Flash Player. This process differs from directly executing code in languages like Python or JavaScript.
Setting up the Environment
To run ActionScript in Sublime Text, you'll need a few essential components:
-
Sublime Text: Download and install the latest version from https://www.sublimetext.com/.
-
Flex SDK: The Flex SDK provides the necessary compiler (mxmlc) and libraries for ActionScript development. Download it from https://www.adobe.com/products/flash-builder/.
-
Sublime Text Build System: Sublime Text build systems automate the compilation and execution process. Create a new build system file (Tools > Build System > New Build System) and paste the following code:
{
"cmd": ["mxmlc", "$file"],
"file_regex": "^[ ]*File \"(...*?)\", line ([0-9]*)",
"selector": "source.actionscript"
}
Explanation:
cmd: Specifies the command to execute. Replace"mxmlc"with the path to your mxmlc compiler if it's not in your system's PATH.file_regex: Defines a regular expression to match the filename and line number for error reporting.selector: Tells Sublime Text to use this build system for files with the "source.actionscript" syntax highlighting.
- Save the build system file: Save it as "ActionScript.sublime-build" in your Sublime Text packages directory (usually found at
~/Library/Application Support/Sublime Text 3/Packageson macOS).
Executing Your Code
Now, you can run your ActionScript code from within Sublime Text:
- Open your ActionScript file: Create a new file or open an existing one.
- Choose the build system: Select "Tools > Build System > ActionScript".
- Run the build: Press
Ctrl+B(Windows/Linux) orCmd+B(macOS) to execute the build system.
Sublime Text will compile your ActionScript code using the mxmlc compiler and display any errors in the console.
Optimizing Your Workflow
- Using External Editors: For larger projects, you might prefer to use dedicated IDEs like Adobe Flash Builder or IntelliJ IDEA, which provide features like code completion, debugging, and project management. Sublime Text can still be used as a lightweight editor for individual files or smaller projects.
- Debugging: While Sublime Text doesn't have built-in debugging capabilities for ActionScript, you can use external debugging tools like the Flash Debug Player or the Debugger in Adobe Flash Builder.
- Extensions and Plugins: Explore the vast Sublime Text Package Control ecosystem for extensions that enhance your workflow. You can find plugins for syntax highlighting, linting, code snippets, and more.

Conclusion
By setting up a simple build system and using the appropriate tools, you can seamlessly integrate ActionScript development within Sublime Text, benefiting from its speed and customization options. Remember to explore the extensive resources available to further enhance your development experience.
