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

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

text/x-agda is the MIME type assigned to files containing Agda source code. Agda is a dependently typed programming language and proof assistant. Its code is written in plain text and is used for both programming and formal verification.

Files marked with this MIME type, such as AGDA, are processed by dedicated Agda tools that offer syntax highlighting, type checking, and proof validation. These tools read the file, analyze its structure, and provide advanced code support.

Main use case:

Authoring proofs and programs in a language designed for both computation and rigorous mathematical proofs.
Syntax highlighting and other editor integrations that enhance readability and reduce errors.
Static analysis where the code is checked for logical consistency before compilation or proof checking.
Formal verification workflows where every line of code may represent a step in a mathematical proof.

This MIME type helps operating systems and software recognize the file content so that developers can get context-specific functionalities during editing and processing.

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.
