### Example that implements a rolling autosave using the autoSaveFilter callbacks
###
## autosaves roll from 0-9 eg myfile.autosave, myfile.autosave1, myfile.autosave2...
#
## To use just add 'import nukescripts.autosave' in your init.py
[docs]def onAutoSave(filename):
## ignore untiled autosave
if nuke.root().name() == 'Root':
return filename
fileNo = 0
files = getAutoSaveFiles(filename)
if len(files) > 0 :
lastFile = files[-1]
# get the last file number
if len(lastFile) > 0:
try:
fileNo = int(lastFile[-1:])
except:
pass
fileNo = fileNo + 1
if ( fileNo > 9 ):
fileNo = 0
if ( fileNo != 0 ):
filename = filename + str(fileNo)
return filename
[docs]def onAutoSaveRestore(filename):
files = getAutoSaveFiles(filename)
if len(files) > 0:
filename = files[-1]
return filename
[docs]def onAutoSaveDelete(filename):
## only delete untiled autosave
if nuke.root().name() == 'Root':
return filename
# return None here to not delete auto save file
return None
[docs]def getAutoSaveFiles(filename):
date_file_list = []
files = glob.glob(filename + '[1-9]')
files.extend( glob.glob(filename) )
for file in files:
# retrieves the stats for the current file as a tuple
# (mode, ino, dev, nlink, uid, gid, size, atime, mtime, ctime)
# the tuple element mtime at index 8 is the last-modified-date
stats = os.stat(file)
# create tuple (year yyyy, month(1-12), day(1-31), hour(0-23), minute(0-59), second(0-59),
# weekday(0-6, 0 is monday), Julian day(1-366), daylight flag(-1,0 or 1)) from seconds since epoch
# note: this tuple can be sorted properly by date and time
lastmod_date = time.localtime(stats[8])
#print image_file, lastmod_date # test
# create list of tuples ready for sorting by date
date_file_tuple = lastmod_date, file
date_file_list.append(date_file_tuple)
date_file_list.sort()
return [ filename for _, filename in date_file_list ]
nuke.addAutoSaveFilter( onAutoSave )
nuke.addAutoSaveRestoreFilter( onAutoSaveRestore )
nuke.addAutoSaveDeleteFilter( onAutoSaveDelete )
### As an example to remove the callbacks use this code
#nuke.removeAutoSaveFilter( onAutoSave )
#nuke.removeAutoSaveRestoreFilter( onAutoSaveRestore )
#nuke.removeAutoSaveDeleteFilter( onAutoSaveDelete )
