Usage:
|
|
python3 mtoldtonew.py <filename>
|
|
or
|
|
python3 mtoldtonew.py <filenames>
|
|
|
|
Examples:
|
|
python3 mtoldtonew.py palm_oldnodes.we
|
|
python3 mtoldtonew.py palm_oldnodes.we palm.we
|
|
|
|
* Example 2 yields: palm_newnodes.we and newpalm.we
|
|
with all nodes replaced according to csv.
|
|
(adds "new" to beginning if "old" is not in specified filename)
|
|
|
|
* only replaces node names surrounded by quotes
|
|
- you can change that behavior using python:
|
|
from mtoldtonew import oldToNew
|
|
oldToNew('file.we', quotechar='')
|
|
|
