| FDNPKG idx builder |
| Copyright (C) Mateusz Viste 2012, 2013, 2014, 2015, 2016, 2017 |
| buildidx computes idx files for FDNPKG-compatible repositories. |
| it must be executed pointing to a directory that stores FreeDOS |
| packages (zip) files. buildidx will generate the index file and |
| save it into the package repository. |
| 23 apr 2017: uncompressed index is no longer created, added CRC32 of zib (bin only) files, if present |
| 28 aug 2016: listing.txt is always written inside the repo dir (instead of inside current dir) |
| 27 aug 2016: accepting full paths to repos (starting with /...) |
| 07 dec 2013: rewritten buildidx in ANSI C89 |
| 19 aug 2013: add a compressed version of the index file to repos (index.gz) |
| 22 jul 2013: creating a listing.txt file with list of packages |
| 18 jul 2013: writing the number of packaged into the first line of the lst file |
| 11 jul 2013: added a switch to 7za to make it case insensitive when extracting lsm files |
| 10 jul 2013: changed unzip calls to 7za (to handle cases when appinfo is compressed with lzma) |
| 04 feb 2013: added CRC32 support |
| 22 sep 2012: forked 1st version from FDUPDATE builder |

| buildidx is a little program that generates index.lst files for FDNPKG repositories out of a directory filled with FreeDOS packages. |
| You DON'T need buildidx if you're only using FDNPKG. This is a tool that can be useful only to administrators hosting and maintaining FDNPKG repositories. I tested (and used) it only on a Linux platform, but it might work on other platforms as well (if you manage to compile it correctly). |
| * Requirements * |
| To operate properly, buildidx needs following tools to be available: |
| - gzip |
| - unzip |
| * How to use it * |
| Put all your packages into a single directory, for ex. "mystuff", and call buildidx with the directory as a parameter: |
| ./buildidx mystuff |
| Then buildidx will compute a index.lst file and store it inside your directory. The directory will be useable as a FDNPKG repository then. |
