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

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

text/x-haskell marks files that contain source code written in the Haskell language. It tells text editors, compilers, and other tools how to handle and display the code properly.
Developers use it for correct syntax highlighting, parsing, and error checking.

• Used in text editors to apply language-specific formatting.
• Processed by Haskell compilers and development tools.
• Enables proper recognition of the file’s structure and language elements.
• Supports a range of files—from actual source code and boot files to literate programming and config files.

Files using this MIME type include those with the source code extension HS and its literate variant LHS. Other examples are preprocessed ones with HSC and mixed-code files like CHS. It also applies to files from related tools and ecosystems, such as BS (Bluespec BH), GF (Grammatical Framework), CABAL (configuration files), DHALL, HS-BOOT, and even PURS from the PureScript community.

Usage Examples

HTTP Header

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

    Content-Type: text/x-haskell
  

HTML

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

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