 **Notes** 

 1 The AWS Cloud9 IDE provides syntax highlighting for many more languages. For a complete list, in the menu bar of the IDE, choose **View, Syntax**.

 2 You can run programs or scripts at the click of a button for languages marked with a **✓**, without using the command line. For languages not marked with a **✓** or not displayed on the **Run, Run With** menu bar in the IDE, you can create a runner for that language. For instructions, see [Create a Builder or Runner](build-run-debug.md#build-run-debug-create-builder-runner).

 3 You can use the IDE's built-in tools to debug programs or scripts for languages marked with a **✓**. For instructions, see [Debug Your Code](build-run-debug.md#build-run-debug-debug).

 4 This feature is in an experimental state for this language. It is not fully implemented and is not documented or supported.

 5 This feature supports only local functions for this language.

 6 Enhanced support for *Java SE 11* features can be activated in AWS Cloud9 EC2 development environments with 2 GiB or more of memory. For more information, see [Enhanced support for Java development](enhanced-java.md).

 7 To specify paths for AWS Cloud9 to use for completion of custom PHP code, in the AWS Cloud9 IDE turn on the **Project, PHP Support, Enable PHP code completion** setting in **Preferences**, and then add the paths to the custom code to the **Project, PHP Support, PHP Completion Include Paths** setting.

 8 To specify paths for AWS Cloud9 to use for completion of custom Python code, in the AWS Cloud9 IDE turn on the **Project, Python Support, Enable Python code completion** setting in **Preferences**, and then add the paths to the custom code to the **Project, Python Support, PYTHONPATH** setting.

 9 The AWS Cloud9 IDE provides additional support for some programming languages, such as TypeScript (version 3.7.5 supported in the AWS Cloud9 IDE), within the context of a language project. For more information, see [Working with Language Projects](projects.md).

## Supported programming language versions in the AWS Cloud9 Integrated Development Environment (IDE)
<a name="programming-language-support"></a>

The table below outlines which versions of programming languages are supported on specific AMIs in the AWS Cloud9 IDE. Ubuntu 18 went EOL in 2023 and as a result the programming language versions cannot be updated in AWS Cloud9.


****  

| *Language* | *Amazon Linux 2023*  | *Amazon Linux 2*  | *Ubuntu 18* | *Ubuntu 22* | 
| --- | --- | --- | --- | --- | 
|  Python3  |  3.9  |  3.8  |  3.6  |  3.10  | 
|  TypeScript  |  3.7.5  |  3.7.5  |  3.7.5  |  3.7.5  | 
|  PHP  |  8.2  |  8.2  |  7.2  |  8.1  | 
|  Ruby  |  3.2  |  3.0  |  3.0  |  3.2  | 
|  Java  |  11, 17  |  11  |  11  |  11, 17  | 
|  Python2  |  N/A  |  2.7  |  N/A  |  N/A  | 
|  C\$1\$1\$1  |  23  | 17 |  17  |  23  | 
|  Go  |  1.20  |  1.20  |  1.9  |  1.21  | 
| CoffeeScript |  2.7  |  2.7  |  2.7  |  2.7  | 

\$1You can run the following command to compile C\$1\$1 files using the version of the programming language you want to use: 

```
g++ -std=c++[version-number] "$file" -o "$file.o"
```
