What is MIME type "application/x-fantom"?

A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.

application/x-fantom designates files containing Fantom source code. These files are typically saved with the FAN extension.
This MIME type is non-standard. It informs systems, web servers, and editors of the file’s coding language and structure. The type helps software treat the file with the rules and syntax of the Fantom language.
Fantom is built for cross-platform development. The MIME type supports its practical uses in several ways:

Main use: Identifies source code files for the Fantom programming language.
Developer support: Enables integrated development environments to apply syntax highlighting, validation, and other coding tools.
Content delivery: Assists web servers in setting correct Content-Type headers when serving Fantom code files.
Project organization: Helps maintainers and programmers recognize and manage Fantom projects effectively.

This specific identification is useful for any workflow involving code processing, editing, or distribution in Fantom. For further reading on Fantom itself, visit the official Fantom website.

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 are multiple MIME types listed for one extension?

Different applications and historical conventions may use alternative MIME identifiers for the same kind of file. Showing them all helps ensure compatibility across systems.
