Yad File Browser

[stemsee]

Yad --icon --read-dir presents desktop files in a directory. If every file and every directory had a .desktop file representing it then that would make for a rudimentary file navigator, with executable functionality and higher levels of custom actionability per file or per dir. This makes for advanced customised security. So my experiment so far was to make a desktop file with the contents.

Code: Select all

[Desktop Entry]
Encoding=UTF-8
Name=root
GenericName=root
Icon=dir.png
Comment=directory
Exec=yad --icons --read-dir=/root
Terminal=false
Type=Application
Categories=File

and yes, it opens up a yad --icons --read-dir instance for /root. However i presently don't have .desktop files in /root representing files and dirs that are there. Of course creating them automatically would be trivial. Each would have an icon corresponding to a limited number of (mime) types. All dirs to any depth can be visible on the top plane, like a flattened tree. Files only get represented on opening a dir.desktop file. The Exec= string can be set automatically or manually. Just a simple backup file system navigator. I wonder how practical it would be?

Code: Select all

#!/bin/bash
for i in $(ls /)
do
echo "[Desktop Entry]
Encoding=UTF-8
Name=$i
GenericName=$i
Icon=dir.png
Comment=$i
Exec=yad --icons --read-dir=/$i
Terminal=false
Type=Application
Categories=File" > /tmp/$i.desktop
done

or better with find -max-depth -exec yfm.sh {} ... etc

Yes! It works as expected.

The best thing is to create directory desktop files next to the represented directory and link all directory desktop files to /tmp. Files get created next to the represented file, and are created according to case statements for appropriate Exec= strings according to file type, mostly text/doc file or executable. Fully working!

EDIT: there are a hell of a lot of desktop files all over the place, so I realise now that they should be moved into their own 'file system structure' in /tmp or /root. Even better made into a system sfs and loaded when required.

Here is a proof of concept. Needs some refinement.

Yad File Browser is a simple file explorer which creates .desktop files with
execute string, icon and information.

Executing this script create a yfb directory in /tmp which is then populated with the
system's functional directories, no virtuals like /proc or /sys.
Then for each directory it creates a $dir.desktop file.
After this file.desktop files are created one for one with the running system.
When the creation processes have finished an yfb.sfs filesystem module is created
from the /tmp/yfb directory. Load this sfs and click on the desktop files
to browse directories and activate files. So far the number of files that can be
activated is not very extensive. Extensions can be added to the case statements
in the cdrdesktop function, along with execute strings and icons. Its use is
presently read only.

It uses yad --icons --read-dir="$dir-path" --monitor.

I may develope this further adding a list view navigator in yad paned mode.
The list view would give many more file manipulation possibilities including a popup menu.

I need to research how to re-use the mime functions of the system instead or creating case statements for every type of extension.
