What is MIME type "text/x-forth"?
A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
text/x-forth is the MIME type for files that contain code written in the Forth programming language. This language uses a stack-based approach and postfix notation to perform operations. It is a plain text format, easily read and edited by any text editor.Files marked with text/x-forth are primarily used to store source code meant for systems that benefit from low-level, interactive control. They often serve in environments where performance and direct hardware manipulation matter, such as embedded systems or legacy applications.
Common file types using this MIME type include code with extensions like FS, M, F, FR, FRT, FOR, MUF, 4TH, FORTH, and FTH.
- Plain Text Nature: The code is human-readable and edit-friendly.
- Stack-Based Operations: Forthโs design emphasizes a simple, efficient runtime model.
- Embedded and Interactive Use: It is common in systems needing close hardware integration.
- Legacy Applications: Many older or specialized projects continue to use Forth.

Usage Examples
HTTP Header
When serving content with this MIME type, set the Content-Type header:
Content-Type: text/x-forth
HTML
In HTML, you can specify the MIME type in various elements:
<a href="file.dat" type="text/x-forth">Download file</a>
Server-side (Node.js)
Setting the Content-Type header in Node.js:
const http = require('http');
http.createServer((req, res) => {
res.setHeader('Content-Type', 'text/x-forth');
res.end('Content here');
}).listen(3000);

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.
