buildidx computes idx files for FDNPKG-compatible repositories.
|
|
|
6 |
it must be executed pointing to a directory that stores FreeDOS
|
|
|
7 |
packages (zip) files. buildidx will generate the index file and
|
|
|
8 |
save it into the package repository.
|
|
|
9 |
|
|
|
10 |
23 apr 2017: uncompressed index is no longer created, added CRC32 of zib (bin only) files, if present
|
|
|
11 |
28 aug 2016: listing.txt is always written inside the repo dir (instead of inside current dir)
|
|
|
12 |
27 aug 2016: accepting full paths to repos (starting with /...)
|
|
|
13 |
07 dec 2013: rewritten buildidx in ANSI C89
|
|
|
14 |
19 aug 2013: add a compressed version of the index file to repos (index.gz)
|
|
|
15 |
22 jul 2013: creating a listing.txt file with list of packages
|
|
|
16 |
18 jul 2013: writing the number of packaged into the first line of the lst file
|
|
|
17 |
11 jul 2013: added a switch to 7za to make it case insensitive when extracting lsm files
|
|
|
18 |
10 jul 2013: changed unzip calls to 7za (to handle cases when appinfo is compressed with lzma)
|
|
|
19 |
04 feb 2013: added CRC32 support
|
|
|
20 |
22 sep 2012: forked 1st version from FDUPDATE builder
