nspx 0.2-6 (NSP eXtractor)

extracts nintendo switch software packages (*.nsp-files)

---

Requirements:

• python (2 and 3 both seem to work)

Packaging requirements:

• pyinstaller: run pyinstaller --onefile nspx.py, result will be in "dist/"

Syntax:

• ./nspx.py -lf example.nsp - lists contents of example.nsp
• ./nspx.py -xf example.nsp - extracts all files from example.nsp into ./example
• ./nspx.py -xf example.nsp icon.jpg - extracts "icon.jpg" from "example.nsp" into "./example" (can add more names to extract)
• ./nspx.py -sxf example.nsp largefile.nca - extracts "largefile.nca" and splits it into 4GB parts, if it is >4GB (WIP, not working yet)
• ./nspx.py -af example.nsp icon.jpg - creates new archive (cannot append files to existing archive, yet)

Changes:

• in v0.2-6d2:
  • changed 'pfs0.py':
    • changed logger function requirements: def logger_fn( log_level: str, msg: str ) -> any
    • PFS0File contructor now takes a pathname instead of a file object
    • PFS0File constructor now accepts a custom logger function, following above requirements
    • PFS0File constructor now stores filenames in memory, instead of reading it per use
    • PFS0File listfiles changed format list( tuple( file_name: str, file_size: int, file_offset: int ), ... )
    • Added update method to PFS0File, that updates file information
    • renamed a lot of variables
  • functionality remains the same
• in v0.2-6d1:
  • Readded splitting using a rewritten function
• in v0.2-5:
  • Added some docstring and comments to "pfs0.py"
  • removed splitted extracting as it doesn't work yet
• in v0.2-4:
  • Note: I haven't had time to thoroughly test the splitting feature, so there could be some errors within the code still
• in v0.2:
  • cleaned up some code
  • put pfs0 code in its own class
  • switched to optparse
