# cfspack
|
|
|
|
A tool/library to pack files into a CFS blob and unpack a CFS blob into
|
|
a directory.
|
|
|
|
## Usage
|
|
|
|
To pack a directory into a CFS blob, run:
|
|
|
|
cfspack /path/to/directory
|
|
|
|
The blob is spit to stdout. If there are subdirectories, they will be prefixes
|
|
to the filenames under it.
|
|
|
|
`cfspack` takes optional -p pattern arguments. If specified, only files
|
|
matching at least one of the patterns ("fnmatch" style") will be included.
|
|
|
|
If path is a file, a CFS with a single file will be spit and its name will
|
|
exclude the directory part of that filename.
|
|
|
|
The chain being spitted is always ended with a "stop block" (a zero-allocation
|
|
block that stops the CFS chain). You can call `cfspack` with no argument to get
|
|
only a stop block.
|
|
|
|
The program errors out if a file name is too long (> 26 bytes) or too big
|
|
(> 0x10000 - 0x20 bytes).
|
|
|
|
To unpack a blob to a directory:
|
|
|
|
cfsunpack /path/to/dest < blob
|
|
|
|
If destination exists, files are created alongside existing ones. If a file to
|
|
unpack already exists, it is overwritten.
