Hi everyone,
my first thought was this should be easy to script with a few lines of
bash. It turns out to be harder than I expected... In the end I came
up with a simple-ish python script [1] which displays "tree" like
output and watches the filesystem for changes, and one process'es
current working directory. That cwd is highlighted in reverse video.
You run it as 'xterm -e python3 followme.py . -p $$' (xterm, urxvt, konsole
work just as well, gnome-terminal is stupid and has different syntax :()
to have a window with
/home/zbyszek/python/followme/
test/
filea
fileb
followme.py
README
One of the directories is highlighted when the shell moves into it.
It's mostly a proof of concept, but it might be useful even in this
form. The nice thing about doing this in a script is that it can be
updated for swc uses, e.g. to skip .git directory, use some nice
formatting, etc.
One thing that should be changed is the formatting: right now 4 spaces
are used to indent children, but replacing it with unicode tree
characters (├──, └──, etc), would increase readability.
Another thing would be adding the blinking of files "looked
at". Currently inotifywait is used to wait for modifications, and it
could be extended to report access/modify/attrib events. "Blinking"
should be doable without too much trouble.
