 Filter options:
  -s, --search [SEARCH...]      Search for files using a substring.
      --smart-case              Searches case insensitively if the pattern is
                                all lowercase. Search case sensitively
                                otherwise. (default: true)

Examples

List content

List based on a search phrase

stormex '/mnt/s1/BnetGameLib/StarCraft II' -s 'buildid' -l

List all files with details and sort by filesize.

stormex '/mnt/s1/BnetGameLib/StarCraft II' -ld | sort -h

Extract files based on inclusion and exclusion patterns

stormex '/mnt/s1/BnetGameLib/StarCraft II' \
  -I '\\(DocumentInfo|Objects|Regions|Triggers)$' \
  -I '\.(fx|xml|txt|json|galaxy|SC2Style|SC2Hotkeys|SC2Lib|TriggerLib|SC2Interface|SC2Locale|SC2Components|SC2Layout)$' \
  -E '(dede|eses|esmx|frfr|itit|kokr|plpl|ptbr|ruru|zhcn|zhtw)\.sc2data' \
  -E '(PreloadAssetDB|TextureReductionValues)\.txt$' \
  -x -o './out'

Extract to stdout

Extract specific file to stdout and pipe the stream to another program. For example convert dds to png and display it with imagick.

stormex -S '/mnt/s1/BnetGameLib/StarCraft II' -X 'mods/core.sc2mod/base.sc2data/EditorData/Images/HeroesEditor_Logo.tga' -p | display tga:

stormex -S '/mnt/s1/BnetGameLib/StarCraft II' -X 'mods/core.sc2mod/base.sc2data/EditorData/Images/EditorLogo.dds' -p | magick dds: png: | display png:

Mount as FUSE filesystem

mkdir -p cascfs
stormex -v -S '/mnt/s1/BnetGameLib/StarCraft II' -m ./cascfs

Result:

$ ls -l ./cascfs
