# =================================
|
|
|
|
# todo: switch to `p4 fstat ...`, and parse the output for clientFile and cache it.
|
|
# todo: have a backup feature, make sure files are moved to the recycle bin or a temporary file.
|
|
# todo: switch to faster method of calling p4 fstat on an entire directory and parsing it's output
|
|
# todo: add option of using send2trash
|
|
# todo: buffer output, after exceeding a certain amount print to the output.
|
|
# todo: allow logging output besides console output, or redirection altogether
