[gentoo-user] mime type experts / *.pps

[gentoo-user] mime type experts / *.pps

[Uwe Thiem]

Hi folks,

this is about Powerpoint Presentations and Gentoo and (almost) any other linux 
distribution. There are two different types of presentations: *.ppt and 
*.pps. The difference is that *.pps have an interpreter linked into the 
document so you can run it under Windows without having Powerpoint.

*.ppt do not cause any problems but *.pps do. If you do a "file something.pps" 
it reports it as "Microsoft Office Document" without qualifying what kind of 
document. 

As long as you have set all your file associations of Microsoft documents to 
OpenOffice, it will work for you because OO still is a monolithic application 
that handles all of them. 

This is not true if you have set file associations of Microsoft documents to 
specific applications in any other office suite, including but not limited to 
koffice. In the case of koffice, kword gets started, It starts to load the 
presentation and decides correctly that this isn't a word document.

So my question is: Aren't there any mime type and/or magic file experts here 
that can extent the magic file to recognise *.pps files correctly?

Would be great if we could get that sorted out.

I tried myself. Unfortunately, I am not a magic file expert and failed 
badly. :-(

The 'file' command and mime types are different things.

If you do a 'file something.ppt', I am fairly certain it will also say
Microsoft Office Document. While grepping for 'Excel' and 'Word' both
turn up some stuff in /usr/share/misc/file/magic, there isn't anything
that corresponds to 'Power' except for PowerPC related stuff. 

In fact, I am pretty sure that documents from newer versions of
Microsoft Office would all return that string when file is ran against
them.

The question is how you are recognizing the files? From what you are
saying, it sounds to me like you are double-clicking in some KDE file
browser and letting KDE do the job of deciding which application to
call. Since I know naught about KDE, I can't help there.

However, one thing that came to mind is for you to check the
mime.types file in /etc/mime.types and make sure

[01:01 PM]wwong ~ $ grep pps /etc/mime.types
application/vnd.ms-powerpoint                   ppt pps

pps files are indeed associated as powerpoint.

Close. It's rather clicking on a mail attachment.

Yup. That line is there.

most simple solution i can give is to rename file.pps to file.ppt

for my understanding pps does only that that opening it starts slide show not 
the editor and powerpoint installation still has to be present

If you are in KDE, then right clicking on the file should give you a "Open 
with..." option in the context menu. Choose that, browse to the application 
you want to use to open the file and then check the "Remember application 
association...". This will set the mime type in KDE. Now just double click 
the file and it will open in your desired application.

If you are rather using Gnome, then I am sure someone using that DE will have 
some ideas.
