Hello,
I've made a [rootinfo] object in my library that gives the path, name, and
relative level of the root canvas.
I also have a [makerpath] object that is supposed to take paths relative to the
root canvas and transform them into absolute paths but it doesn't seem to work
correctly... I will update it tonight though.
available here https://github.com/sebshader/shadylib
might be in deken for linux and OS X.. not sure (thought the updated
abstraction will only be on Github)

Subject: [PD] Best way to make file paths relative to the parent patch ?
Hi,
To explain myself, i have to describe a practical example
(http://reso-nance.org/public/pd-malinette/test-paths.png) :
- you write an [audio-sampler] abstraction in "abs" directory, which
load soundfiles
- you write a "main.pd" patch where you put this abstraction in the
project directory
- you want to load the "data/snare.wav" sound file with a message
connected to the abstraction
Result : the context of the abstraction is in "abs" directory, so it
can't find "data/snare.wav" (there is no "abs/data/snare.wav" file), instead
we have to write "../data/snare.wav" relative to the abstraction and not the
parent patch.
A common solution to deal with that is to add [ggee/getdir 1] inside
the abstraction, to get the absolute path of the file starting from the
upper level (parent patch). But if the abstraction is inside another
abstraction, it has to be [ggee/getdir 2] and so on ... But how find the
right depths of the abstraction ? The abstraction doesn't know his context
of use.
I think I will put a [ggee/getdir 10] or greater to be sure to get the
parent patch level, but maybe someone has another solution, a vanilla
solution ?
