The nodejs implementation of StormLib's pkware compressor/de-compressor

Package Exports

  • node-pkware

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (node-pkware) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

node-pkware

nodejs implementation of StormLib compression/decompression algorithm

it was the de-facto compression for games from around Y2K, like Arx Fatalis

installation / update existing version

npm i -g node-pkware

recommended node version: 8.5+

tested in node version 12.7.0

command line interface

implode <filename> --output=<filename> --keep-header --ascii|--binary --level=1|2|3 - compresses file. if --output is omitted, then output will be placed next to input and names as <filename>.compressed. optionally you can specify an offset from which the compressed data starts with the --offset=<int|hex>, which is useful for mixed files, such as the fts files of Arx Fatalis

explode <filename> --output=<filename> --keep-header - decompresses file. if --output is omitted, then output will be placed next to input and names as <filename>.decompressed. optionally you can specify an offset from which the compressed data starts with the --offset=<int|hex>, which is useful for mixed files, such as the fts files of Arx Fatalis

The --keep-header flag tells node-pkware to keep the portion before --offset and attach it to the output file.

examples

explode test/files/fast.fts --output=C:/fast.fts.decompressed --offset=1816 --keep-header

explode test/files/fast.fts --output=C:/fast.fts.decompressed --offset=0x718 --keep-header

implode test/files/fast.fts.unpacked --output=C:/fast.fts --binary --level=3 --offset=1816 --keep-header

piping also works

cat c:/arx/level8.llf | explode > c:/arx/level8.llf.unpacked --keep-header

explode c:/arx/level8.llf > c:/arx/level8.llf.unpacked --keep-header

cat c:/arx/level8.llf | explode --output=c:/arx/level8.llf.unpacked --keep-header

cat e:/piping/level8.llf.unpacked | implode --binary --level=3 > e:/piping/level8.llf.comp2 --keep-header

implode e:/piping/level8.llf.unpacked --binary --level=3 > e:/piping/level8.llf.comp --keep-header

cat e:/piping/level8.llf.unpacked | implode --binary --level=3 --output="e:/piping/level8.llf.comp2" --keep-header
