Simple Archiver
This program is not yet almost basically finished! Basic Necessary
functionality is implemented and only some advanced features are missing
some extra features are not yet implemented. You can track progress
here.
This program exists because I could not get tar or ar to compile with
Cosmopolitan. Thus, this
archiver will be written with support for Cosmopolitan in mind. This means
sticking to the C programming language and possibly using Cosmopolitan-specfic
API calls.
Usage
Usage flags:
-c : create archive file
-x : extract archive file
-t : examine archive file
-f <filename> : filename to work on
Use "-f -" to work on stdout when creating archive or stdin when reading archive
NOTICE: "-f" is not affected by "-C"!
-C <dir> : Change current working directory before archiving/extracting
--compressor <full_compress_cmd> : requires --decompressor and cmd must use stdin/stdout
--decompressor <full_decompress_cmd> : requires --compressor and cmd must use stdin/stdout
Specifying "--decompressor" when extracting overrides archive file's stored decompressor cmd
--overwrite-create : allows overwriting an archive file
--overwrite-extract : allows overwriting when extracting
--no-abs-symlink : do not store absolute paths for symlinks
--temp-files-dir <dir> : where to store temporary files created when compressing (defaults to current working directory)
--write-version <version> : Force write version file format (default 1)
--chunk-min-size <bytes> : v1 file format minimum chunk size (default 4194304 or 4MiB)
--no-pre-sort-files : do NOT pre-sort files by size (by default enabled so that the first file is the largest)
-- : specifies remaining arguments are files to archive/extract
If creating archive file, remaining args specify files to archive.
If extracting archive file, remaining args specify files to extract.
Note that --compressor and --decompressor cmds must accept data from stdin
and return processed data to stdout.
