What is MIME type "text/x-rebol"?

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

text/x-rebol is a MIME type for files that hold REBOL code.
It tells software that the file is plain text with REBOL instructions.
The "x-" prefix marks it as a nonstandard type used for specialized languages.

It helps text editors offer proper syntax highlighting.
It guides applications to treat the file as code rather than generic text.
It is used for scripting, configuration, and automation with REBOL.

Files with this type often use extensions like R, R3, or REB.
This designation ensures that systems handle REBOL scripts correctly.

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.
