Hi all,
i try to find a way to read a txt file based on the script name
os.path.dirname(nuke.Root().name()) on ScriptLoad.
I have a panel with a String_Knob. If the knob is changed a txt file is written
to the script path. With a Load Button i can load the txt file back into the
string but i want nuke to do this on start without a button.
Its working with a txt file in the plugin path. But i think its because of how
nuke starts - init and menu.py first?!
For me, who is new to python it must be something like this, but it doesnt work:
class TextFile(nukescripts.PythonPanel):
def __init__(self):
nukescripts.PythonPanel.__init__(self, 'Textfile', 'com.xy.Textfile')
self.Load()
# String
self.Project = nuke.File_Knob('Name', 'Name')
self.addKnob( self.Project )
# KNOBS DEFINITION
def knobChanged( self, knob ):
if knob == self.Name:
self.WriteFile()
# WRITE STRINGS TO TXT FILE IN THE NUKE_SCRIPT DIR
def WriteFile( self ):
if (os.path.dirname(nuke.Root().name()) != ''):
# NUKE_SCRIPT PATH AND TXT NAME DEFINITION
scPath = os.path.dirname(nuke.Root().name())
bin = scPath + '/' + 'TxtBin'
file = "Textfile.txt"
# MAKE DIRECTORY
path = bin + os.sep + file
if not os.path.exists(bin):
os.mkdir(bin)
# WRITE STRINGS
shotinfo = open(path, "w")
shotinfo.write('Name:' + self.Name.value() + '\n')
# READ TXT FILE BACK TO STRINGS
def Load( self ):
if (nuke.Root().name()) != 'Root' :
# NUKE_SCRIPT PATH AND TXT NAME DEFINITION
scPath = os.path.dirname(nuke.Root().name())
bin = scPath + '/' + 'TxtBin'
file = "Textfile.txt"
infotext = bin + '/' + file
openfile = open(infotext, 'r')
array = []
for line in openfile:
x=line
if (x.find('\n') > -1):
line = str(line).replace('\n', '',5)
array.append( line )
# READ LINE VALUES
self.Name.setValue(str(array[0]).replace('Name:', '',1))
self.WriteFile()
So why doesnt it work with self.Load() at the beginning? It seems that Nuke
wants to set the Values for the string before the Panel is loaded.
I dont have a solution. So if you know what i did wrong please let me know.
