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

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

The text/x-janet MIME type marks plain text files that hold code written in the Janet language. These files follow a custom syntax that lets editors and development tools apply special formatting and error checking.
It tells software that the file, often with the JANET extension, contains script code rather than ordinary text.

Main use: Identifying files that include source code created with the Janet language.
Syntax highlighting: Enabling text editors to apply code-specific coloring and rules.
Proper handling: Assisting web servers and tools to process the file as code.
Development clarity: Distinguishing script files from other text documents.

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.
