Au final, en demandant gentiment au shell de demander à python de tagger
com.apple.FinderInfo au bon endroit :
AppleScript :
set myscriptpython to "'/Volumes/macintosh_hd/ChangeLabelColor.py'" # le
chemin du script ci-dessous
set zecolor to choose from list {"none", "gray", "green", "purple",
"blue", "yellow", "red", "orange"} with prompt "Choisir une couleur"
tell application "Finder" to set filestotag to the selection as alias list
-- ou droplet...
repeat with f in filestotag do shell script "python " & myscriptpython &
space & quoted form of POSIX path of f & space & zecolor
end repeat
Python (texte à enregistrer nom_du_script.py) :
#!/usr/bin/env python
import sys
myfilepath=sys.argv[1]
mycolor=sys.argv[2]
from xattr import xattr
def set_label(filename, color_name):
colors = ['none', 'gray', 'green', 'purple', 'blue', 'yellow', 'red',
'orange']
key = u'com.apple.FinderInfo'
attrs = xattr(filename)
current = attrs.copy().get(key, chr(0)*32)
changed = current[:9] + chr(colors.index(color_name)*2) + current[10:]
attrs.set(key, changed)
set_label(myfilepath, mycolor)
