# Tar for ABAP
This is an implementation of the [ustar](https://en.wikipedia.org/wiki/Tar_(computing)) and [pax](https://en.wikipedia.org/wiki/Pax_(command)) tar formats.
Archives can be compressed and decompressed using [gzip and gunzip](https://en.wikipedia.org/wiki/Gzip) methods as well.
NO WARRANTIES, [MIT License](https://github.com/abapPM/ABAP-Tar/blob/main/LICENSE)
Limitations: Block size is hardcoded to 512 bytes
## Usage
### Tar Files
Here's an example of how to tar a list of files.
```abap
DATA your_files TYPE zcl_tar=>ty_files.
DATA(tar) = zcl_tar=>new( ).
LOOP AT files INTO ls_file.
tar->append(
name = file-name
content = file-content
date = file-date
time = file-time
mode = file-mode
typeflag = file-typeflag ).
ENDLOOP.
DATA(tar_data) = tar->save( ).
" Gzip
DATA(packed_data) = tar->gzip( tar_data ).
```
### Untar Files
Here's an example of how to untar a file.
```abap
DATA:
your_data TYPE xstring,
unpacked_data TYPE xstring.
DATA(tar) = zcl_tar=>new( ).
" Gunzip
IF filename CP '*.tgz' OR filename CP '*.tar.gz'.
unpacked_data = tar->gunzip( your_data ).
ELSE.
unpacked_data = your_data.
ENDIF.
tar->load( unpacked_data ).
```
List the files and get file content:
```abap
DATA(files) = tar->list( ).
LOOP AT files INTO DATA(file).
DATA(content) = tar->get( file-name ).
" ...
ENDLOOP.
```
You can use program `Z_TAR_TESTER` to test the methods:
- upload a tar file
- untar it
- tar it again
- save it as a clone of the original tar file
