Using nnn filemanager

So I decided to try it, and like it, how ever it uses Gimp by default to open/view any images, and I read the manual, but can not find anything on how to change that.
I would like to have it using ImageMagick as the default if possible, anyone know how to change that ?

It uses xdg-open so it's likely that xdg-open is pointing to GIMP for images. You'll have to change it there.

Thanks

It is indeed using xdg-open to determine default applications.
Also:
nnn does not use a config file. Instead it uses environmental variables from ~/.profile
for example: export NNN_SCRIPT="$HOME/.scripts/myScript
or for bookmarks:
export NNN_BMS="h:~;d:~/Documents;D:~/Downloads;w:~/Work;W:~/Work/.prn"
In nnn if you press "?" it will print out list of all hotkeys and stuff. (press "q" to go back to file browser)

ImageMagick? Try feh (feh-2.27.tgz)!

Ok, thanks,

Also:
nnn does not use a config file.

I noticed that in the manual, but I still am not even coming close to understand this, I also looked at
'man xdg-open', which also suggested 'xdg-settings' and the xdg-setttings even had some examples, but only for :

xdg-settings check default-web-browser firefox.desktop

Set the default web browser to google-chrome.desktop

xdg-settings set default-web-browser google-chrome.desktop

Set the default mailto URL scheme handler to be evolution.desktop

xdg-settings set default-url-scheme-handler mailto evolution.desk

Nothing on default graphics, ... I did see though, where there was a "gimp.desktop" file, so that gave me a idea, and it worked, I deleted the "Gimp" package, and now it (nnn) opens any images with the "netsurf" browser, which is ok since usually that is all I want to do is view the image.
I noticed with the key board shortcuts, or hotkeys,

In nnn if you press "?" it will print out list of all hotkeys and stuff.

    ^O | Open with...

But using "^O " does not seem to give me any "open with" option,... any way , thanks for the "hints",

Check default app:
xdg-mime query default image/png

Set feh as default app:
xdg-mime default feh.desktop image/png
xdg-mime default feh.desktop image/jpg
xdg-mime default feh.desktop image/bmp
for ImageMagick it should be something like display-im6.desktop

Thanks, That works, now it is using "feh" to open the images. If I want to use ImageMagick, I need to look into that more, but it probably will be easier to simpl use the 'display' command, when I want to open a image with ImageMagick,.. Thanks

[victorvas]

You're welcome. ImageMagick is actually a set of tools, and it's tool for displaying images is display, however it's *.desktop name is different (something like display-im6.desktop).

In Linux there is display-im6.desktop, but in OpenBSD you need to create one.

as root:
cd /usr/local/share/applications/
cp feh.desktop display-im6.desktop

then edit display-im6.desktop, replacing feh:

[Desktop Entry]
Name=ImageMagick
GenericName=Image viewer
Comment=Display and edit image files
Exec=display %U
Terminal=false
Type=Application
Icon=display-im6
Categories=Graphics;
MimeType=image/bmp;image/gif;image/jpeg;image/jpg;image/pjpeg;image/png;image/tiff;image/x-bmp;image/x-pcx;image/x-png;image/x-portable-anymap;image/x-portable-bitmap;image/x-portable-graymap;image/x-portable-pixmap;image/x-tga;image/x-xbitmap;

then:
chown root:bin display-im6.desktop


as regular user:

xdg-mime default display-im6.desktop image/png
xdg-mime default display-im6.desktop image/jpg
xdg-mime default display-im6.desktop image/bmp

etc. for other mime types you need to be opened in ImageMagick

Thanks, Yes, that was the conclusion I came to as well, I had searched and searched, and did not find one, so was figuring I would need to create one, but had not begun to try that.
