About .at Files
AT files are files containing source code written in the AmbientTalk programming language.
They are plain text files recognized with the MIME type text/x-ambienttalk.
- Main Use Case: Writing and storing AmbientTalk code for distributed and parallel computing.
- Editing: Can be opened and modified with basic text editors (e.g., Notepad++, Visual Studio Code) or AmbientTalk-specific IDEs.
- Technical Fact: The file’s text format allows easy sharing and version control within collaborative projects.
Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQs
What is an .at file?
An .at file contains source code written in AmbientTalk, an experimental object-oriented programming language designed for distributed mobile networks. These are plain text files that define the logic and behavior of AmbientTalk applications.
How do I open and edit an .at file?
Because .at files are plain text, you can use any text editor such as Microsoft Notepad, Apple TextEdit, Notepad++, or Visual Studio Code. For the best experience, developers often use editors that support syntax highlighting for custom languages.
How can I run the code inside an .at file?
You need the AmbientTalk interpreter, which usually runs on the Java Virtual Machine (JVM). Typically, you execute these files via the command line using a command similar to java -jar ambienttalk.jar yourfile.at.
Is the .at file extension related to the Linux 'at' command?
No, the .at extension is unrelated to the Unix/Linux at command used for scheduling tasks. While the names are identical, the file extension strictly denotes AmbientTalk source code, whereas the command is a system utility.
What MIME type should be used for serving .at files?
The correct media type is text/x-ambienttalk. Configuring your server with this MIME type helps client applications identify the content as AmbientTalk source code rather than generic text.
Can I convert an .at file to other formats?
Since it is a text-based format, you can easily convert it to .txt by renaming it or saving it as a text file. You can also print the code to .pdf for documentation purposes, though converting it prevents the code from being executable.
Why does my computer not recognize the .at file extension?
Most operating systems do not come with AmbientTalk installed by default. To fix this, you must install the AmbientTalk environment and manually associate the .at extension with your preferred text editor or the AmbientTalk runner.
General FAQ
What is a MIME type?
A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.
MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.
MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.
How do I find the MIME type for a file?
You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.
Why can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
