I've looked into this before but haven't found a satisfactory answer. At best, you can get the offending MIME types to open in a third party text viewer. But I don't know how to force the internal text viewer.

Actually, a thought occurs. The address bar prefix view-source: works for html. As in, "http://www.haskell.org" -> "view-source:http://www.haskell.org". This might be an effective workaround though I don't have a page to test it on right now.

hmm, taking http://darcs.haskell.org/ghc-6.6/packages/base/Data/Map.hs that works, but it's rather inconvenient to convince Firefox to put the URL into the address bar so I can type view-source in front. I had to use "copy link location", make a new tab, and paste into the empty address bar (unless there's some way I didn't find) ISaac

I believe those kinds of problem have to do with the MIME-encoding on the server side: The server uses text/x-haskell. For Firefox to display the document inline it probably has to be text/plain. Not sure what the proper fix is, though.

It should probably be fixed in one of the Apache config files. In the HTTP headers from darcs.haskell.org (viewed with the Live HTTP headers extension in FireFox) I'm getting Server: Apache/2.2.3 (Debian) Content-Type: text/x-haskell returned when I request the Map.hs file. For Apache 2.2 there seem to be various solutions. The web admin should probably be looking at these sorts of things http://httpd.apache.org/docs/2.2/mod/mod_mime.html#addtype http://httpd.apache.org/docs/2.2/mod/core.html#forcetype http://httpd.apache.org/docs/2.2/mod/core.html#defaulttype and maybe rummaging in file httpd.conf Richard.

It is really annoying, and it is an astoundingly old bug in firefox. Apparently it's very hard to fix due to annoying details of the firefox architecture.

It would be simplest for everyone if haskell.org was prepared to send out the files as text/plain (even though this is the wrong mime type), as I believe it used to do. ...

Yes, it does appear to be a bug in Firefox https://bugzilla.mozilla.org/show_bug.cgi?id=57342 not to attempt to display text/x-haskell as if it were text/plain, but to get really obsessive I'm not convinced text/plain is strictly speaking the 'wrong' media-type if that's what the user-agent requests. For example, my FireFox 1.5.0.5 says to the server it will Accept these media-types text/xml, application/xml, application/xhtml+xml, text/html; q=0.9, text/plain; q=0.8, image/png,*/*; q=0.5 This is in order of what it would most like to get back from the server. The server then goes off and tries to find the best media-type for my browser - it can supply different ones depending on what the browser says it wants. By returning it as text/x-haskell the server has given the resource to my browser in */* which is the least wanted media-type. This is perfectly correct behaviour, but if the server was also capable of providing the same thing as text/plain it would be better to give this, or even better a pretty coloured text/html one if the server had one available. I think the underlying file returned as text/x-haskell or text/plain can be the exact same file assuming all x-haskell are also plain. Could be wrong, but that's my understanding of content negotiation. Richard.

Adding the following to my lighttpd config (on Ubuntu Feisty) solves the problem from the server side:

#### external configuration files ## mimetype mapping

# change mime type for haskell source files so they get displayed # inside the browser include_shell "/usr/share/lighttpd/create-mime.assign.pl" mimetype.assign += ( ".hs" => "text/plain", ".lhs" => "text/plain" )

Fortunately the new haddock uses hscolour, so HS files are served as (colourised!) HTML and the problem is no longer a problem, for me. Jules

My problem is when viewing plain darcs repositories (like mine on darcs.johantibell.com which I recently fixed with the above mime type hack.)

Please complain to your browser('s authors): most browsers only provide *one* way to view a given mime-type, which is stupid. It's not specific to .hs files. They could at least provide a way to override the provided mime-type, so you can say "display this application/octet-stream file as a text/plain". Similarly they should allow you to choose (via a context-menu, for example) to open a pdf file in the pdf plugin or in a separate application. Stefan

This extension allows this in firefox. it gives you an 'open in browser as' option that lets you view links in a variety of ways rather than being forced to download it. http://www.spasche.net/mozilla/ John -- John Meacham - ⑆repetae.net⑆john⑈
