What is %F ?

I can launch mimeedit without argument from commandline.
So i inserted %F in settings after path to mimeedit. (Lets'a abbreviate it m.e.)
However, clicking on Settings - >edit mimetypes still doesn't launch.
xession log shows mimeedit 'usage' saying it expects an argument.

sloppy language, pls excuse. of course eog.desktop


ok...i did some testing. Here's the log...i hope you can draw some conclusions 
of it.

About launching without argument.

When i launch m.e. from commandline without argument, the 'program selector' 
pops up.
Selecting kde-amarok.desktop gives empty window.
I remember i copied the /usr/share/applications/kde/amarok.desktop file and 
erased unneccesary international naming stuff. 
Here is the actual content:

[Desktop Entry]
Type=Application
Encoding=UTF-8
Name=Amarok
GenericName=Audio Player
Exec=amarok %U
Comment=Rocks.
Icon=amarok
X-KDE-Protocols=http

(%U - is that a problem?)

As a sidenote, i'm slightly confused. Do you know why some mimetypes are like 
x-* (like x-mp3) while others are like audio/mpeg ? While there is no audio/mp3.
However, i see audio/vorbis and additionally audio/x-vorbis...
Is there a complete list of all known mimetypes anywhere ?

Here is my users applications directory list:

defaults.list
mimeinfo.cache
iceweasel.desktop
Google-googleearth.desktop
ktorrent-usercustom.desktop
vlc-usercreated.desktop
file-roller-usercreated.desktop
mcview-usercreated.desktop
gedit-usercreated.desktop
dillo-usercreated.desktop

evince-usercreated.desktop
eog-usercreated.desktop
exrdisplay-usercreated.desktop
gliv-usercreated.desktop
gqview-usercreated.desktop
gv-usercreated.desktop
xine-usercreated.desktop

I attach defaults.list and mimeinfo.cache. Note the [] headers!

Some general notes about the selector:

- After selecting an app (and possibly editing) the script exits.
Perhaps it's more convenient to return to selector ? Because, after editing one 
file a user could get the idea to edit more.

- The mimeinfo and default files aren't sorted, somehow sucking if you search 
for something visually. Your script would be a good hook-in to do that,  as a 
nice side-effect :)
You could apply sort -u (just to be on the safe side). (Don't forget the header)

Here's something i note since long.
As a test case, let's focus on mp3: I can't the heck get gcmd launch amarok by 
default. It always launched audacity. gcmd reports that as default app.
However, i have amarok in defaults and mimeinfo for mpeg, and no audacity 
anywhere at all. Yet gcmd Alt+Enter reports audio/mpeg as mimetype. But m.e. 
has amarok 'marked'.

What means "FASLE  vlc.desktop" ? What means "soundconverter  No_name" ?
It also has a checkbox with an empty line at the end. 


I tried m.e. on an mp3 file and modified the default to audacity. That was 
applied correctly in mimeinfo and defaults. I repeated that setting amarok 
again. Also applpied correctly.
gcmd still reports audacity for audio/mpeg, and launches it accordingly.
Is this a bug ?

I tried that. 
After relaunching amarok (hoping it would create a new entry), i still have no 
kde-amarok  in the folder. I conclude that's only created on user request, by a 
filemanager like nautilus (or now, m.e.). 

I also restarted the session. Clicking a mp3 in gcmd still opens audacity 
again, with ~/.local/share/applications still empty. Give me a brick.

My theory: The kde-amarok entry somehow is bad. Therefore the next application 
would be chosen. However, there is none defined by user so /etc/mailcap is 
used. There's indeed that audacity entry, and none for amarok. Since i don't 
want to fiddle with mailcap at all, i tried to setup a new amarok entry with 
m.e.
(btw there's a message text artefact on top of that dialog '...separate them 
with a colon' is redundant) but it says 'audio/mpeg already is assigned to 
amarok'. Yet it displays audacity checked ! When i checked kde-amarok instead, 
it says 'dafult was not changed'.
Later, it still shows audacity as default. The relevant files still contain 
amarok.
Why does it show audacity now as default ?

Interesting. I renamed kde-amarok.desktop to just amarok.desktop but m.e. still 
has the old kde-amarok entry (and missing the new one).
Restarting gcmd didn't change that fact.
Then i also deleted the pointer entries in mimeinfo and defaults, and again 
restarted gcmd.
Still m.e. shows kde-amarok...!

ok. I restarted the session.
m.e. still shows kde-amarok!

I removed the audio/x-mp3 entry in defaults.list - still kde-amarok.
I removed that entry in mimeinfo.cache - still kde-amarok !
(there was a [Default Applications] header artefact in mimeinfo now, sonewhere 
in between, additionally to the regular [MIME Cache] header -- i remember to 
have seen that before. Is that m.e. putting it there ?)

I replaced any kde-amarok.desktop entry by amarok.desktop, and restarted gcmd.
Now...amarok is launched as default, by gcmd! But m.e. still shows kde-amarok 
FALSE, and no amarok.desktop entry. It also shows MPlayer FALSE...
That'S weird though. Why without .desktop suffix ? Why FASLE ? There is no 
mplayer desktop file, and no pointer entry at all, in any file, as a grep 
reveals.
mplayer is installed of course. I can launch it via gmcd.

I restarted the session again (and this time ensured no gnome daemon still 
running)
Yet m.e. has kde-amarok  FASLE ...and even a grep could not find any kde-amarok 
anywhere. Why does m.e. not show my amarok.desktop file ? It's in defaults and 
mimeinfo, and work via gmcd now.


I launched m.e. selector (no args). It shows amarok, not kde-amarok.
However, trying to edit amarok.desktop doesn't work. stderr says, 
cat: /usr/share/applications/amarok.desktop: No such file or directory
- so i assume m.e. looks for .desktop files in /usr/share.
ok, i accepted the unavoidable and for heavens sake renamed it to 
amarok-usercreated.desktop. (I think, however, that any file in 
~/.local/share/applications should be considered to be usercreated or 
usercustom or whatever, just as a matter of facts, so the name should be 
irrelevant)

....m.e. still has kde-amarok.

I give up ! It's very late and i already spent several hours on that.

No kde-amarok...i think i gcopied that file some months ago, and they removed 
it meanwhile (replacing it by just amarok.desktop), as there are no other kde-* 
files anymore. 

I wonder about the above kde files. For example the arts entry says 
Exec=kcmshell arts, but i have no arts installed. There's another entry 
'audiocd' with Exec=kcmshell audiocd, but there's no program of that name. You 
can also see 'colors' and 'bell' and 'cookies' and 'dma' and such stuff. Even a 
desktop.desktop entry, (which contains a 'Docpath' entry launching kcontrol and 
siplaying some index.html file.)

This all looks like internal kde proxies/frontends  (e.g. providing that 
inserted audiocd will be recognized and autplayed). 

I can see no kde file at all in /usr/share/applications, with 2 exceptions: 
qt4config (not  strictly a kde app) and k3b, which - funny enough - has no 
entry in the kde subfolder.
Maybe it's no more seen as strict kde app.

Magnus, i don't like to shock you even more, but i feel obliged to mention that 
there seems to exist yet another system in /usr/share/application-registry. 
Folder listing:

openoffice.applications
mplayer.applications
gimp.applications
java-archive.applications
java-web-start.applications
gnome-vfs.applications
cinepaint.applications
gqview.applications
inkscape.applications

For example, gimp entry looks like

gimp
        command=gimp-2.4
        name=GNU Image Manipulation Program
        can_open_multiple_files=true
        expects_uris=non-file
        requires_terminal=false
        supported_uri_schemes=file,http,ftp
        
mime_types=image/bmp,image/g3fax,image/gif,image/jpeg,image/png,image/tiff,image/x-bmp,image/x-compressed-xcf,image/x-pcx,image/x-png,image/x-portable-anymap,image/x-portable-bitmap,image/x-portable-graymap,image/x-portable-pixmap,image/x-psd,image/x-sun-raster,image/x-tga,image/x-xbitmap,image/x-xcf,image/x-xpixmap,image/x-xwindowdump

Another weird thing is, there isn't any /usr/share/amarok folder, but usually 
packages have some shared default files like themes, icons there. There are 
e.g. bluefish, claws-mail, or audacity, and many many others (including all 
debian tools.)

However, there's /usr/share/apps and there is amarok, k3b, digikam, quanta, 
krusader, and all the other kde stuff. And a folder LICENSES with gpl, 
artistic, bsd licenses...

To me that all looks like either KDE doesn't interpret freredesktop like gnome, 
or maybe they just aren't ready for that by now. This is KDE 3.5.8.

Not to mention googleearth - they have a desktop entry now in the right place 
now, but there's still this ~/.local/share/mime folder with its own structure. 
I believe this is an obsolete artefact now, and i'll try out if i can delete it 
safely.

-- I moved back my previous 'applications' folder for the time being. I added 
much stuff there, especially weird mimetypes (like audio/aac or video/3gp, for 
noka mobile files) and i would appreciate not having to put it up again from 
scratch.

I would really like to know how to start the 'selector' from gcmd via 
Settings-Edit mimetypes. And i like to know a more efficient way to test m.e. - 
do i always have to restart gcmd, or restart the session ?
