What is MIME type "text/s"?

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

The MIME type text/s designates a file containing plain text that holds S source code. It tells programs that the file is not binary and should be handled as text. This allows code editors, compilers, and interpreters to apply proper syntax rules.

Its main purpose is to ensure that any system processing the file knows it contains S language instructions. As a text format, it supports features like syntax highlighting and easy editing.

Used for S source code files.
Helps applications recognize and process plain text content.
Enables appropriate handling on web servers and in editors.
Facilitates debugging and code maintenance thanks to its text-based nature.

Files with this MIME type typically have the extension S.

Usage Examples

HTTP Header

When serving content with this MIME type, set the Content-Type header:


    Content-Type: text/s

HTML

In HTML, you can specify the MIME type in various elements:


    <a href="file.dat" type="text/s">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/s');    
      res.end('Content here');    
    }).listen(3000);

FAQs

What software is needed to open a text/s file?

You can open these files with any standard text editor, such as Notepad++, Visual Studio Code, or Vim. Since the MIME type text/s indicates plain text content, you do not need a specific compiler just to view or edit the source code.

How do I configure Apache to serve .s files as text/s?

Add the directive AddType text/s .s to your .htaccess file or the main Apache configuration file. This ensures that when a user accesses an S source code file, the server correctly identifies it as text rather than a generic binary stream.

Why does the browser display the code instead of downloading it?

Browsers are designed to render text/* MIME types inline by default. If you prefer to force a file download for your users, you must configure your web server to send the Content-Disposition: attachment header along with the file.

Is text/s a standard IANA registered type?

No, text/s is not a standard type in the official IANA registry; it is a convention used to specifically identify S language source code. For broader compatibility, some systems might default to text/plain if they do not recognize this specific subtype.

How do I add text/s support to an Nginx server?

You can add the mapping by editing your mime.types file or the types block in your nginx.conf. Insert the line text/s s; to ensure Nginx serves files with the S extension using the correct content type.

Are text/s files executable programs?

No, files served with this MIME type contain source code, which is human-readable text. To run the program, the code must typically be processed by an S language interpreter or compiled into a binary format, depending on the specific implementation.

What is the relationship between S source code and the R language?

The S language is the predecessor to the modern R programming language. While R files typically use .r, legacy code or scripts written specifically for S implementations often use the .s extension and may be identified by this MIME type.

General 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.
