What it's about:
I've been searching for a simple filetagger.
Just to tag any file to be able to find it later by simply searching for a tag.
What i find is heavy bloated QT/KDE taggers for media files, that alter fileheaders for e.g. audio or image files.
Not my intention...
I was looking for a standalone app to tag files independent from it's filetype.
So i recalled what my mother in law always used to say: help yourself!
Now this is what i got so far:
A standalone app that stores filenames associated with tags and comments in a local database.
Code: Select all
#!/bin/bash
APP="$(readlink -f "$0")"
HERE="${APP%/*}"
TEMP="/tmp/gtagger"
mkdir "$TEMP" 2>/dev/null
cd "$TEMP" || exit
MIMEICONS="/usr/share/icons/PMaterial/scalable/mimetypes"
DB="$HERE/tags0.3.csv"
export DB HERE MIMEICONS TEMP

If you want to try it, make sure to run this from its' own directory - it's intended to run as ROX AppDir later...
As always i don't dare to publish this without someone having a look at it before. 
My doubts are about:
adding new entry in a running instance
the search function, espescally using grep -P and its' syntax
This got more complex than it was intended to be 
If you find any similarity to @MochiMoppel's mm_view - it's not accidentally 
Though i started from scratch and just had an eye on how things work... (editing other people's code can be a PITA...)
Internationalization needs to be implemented in the future, IF this get's published anyway.
Any thoughts on this?
