Description
tar is a module to access tar archives.
Tape archives (tar) are a file format for storing a sequence of files that can be read and written
as streams. This module covers the reading of the basic sections of archives produced by GNU tools
like Linux command tar -xvf but in memory instead modifing the filesystem. Parses directories,
files, and file's content and manage paths longer than 100 chars.
Read Efficiency
An entire tar file can be read in memory or by chunks. Keeps in memory a single decompressed chunk of 32 KB at a time and also keeps in memory a single tar block of 512 bytes at a time. Convert paths to strings until needed and the user reader implementation can stop early the reading process.
Read Example
The tar blocks are parsed and some fields are passed to Reader implemented methods.
import os
import archive.tar
fn main() {
os.chdir(@VMODROOT) or {}
path := 'archive/tar/testdata/life.tar.gz'
reader := tar.new_debug_reader()
tar.read_tar_gz_file(path, reader)!
}
