# elvis: slack -- Search Slackware.com packages

# Licensed under the WTFPL. See http://www.wtfpl.net/txt/copying/ for details.
# Unfortunately we can't use get with this form. Well, we can,
# except the checkboxes for "search sets" don't work. So it has
# to be a post request, which means this elvis depends on wget. I
# suppose it could support curl instead (or in addition) but I don't
# see the point.
# The source search is pretty useless, but that's not this script's fault.

Usage: $w3_argv0 [options] [search words]...
Description:
Surfraw search Slackware.com packages
Local options:
-v=<version> Slackware version (default $SURFRAW_slack_ver).
For .0 releases, include the .0 (eg 14.0, not 14).
-C, -cur Same as -v=current
-32/-i586, -64/-x86_64 Architecture (default -$defarch)
-pa, -pkg, -P Package search (default)
-d, -desc Description search
-l, -label Label search
-c, -content Content search
-s=<sets> Search sets, <sets> may consist of:
e = extra
P = pasture
p = patches
s = slackware
S = source
t = testing
Default: $SURFRAW_slack_sets
-S, -src Search source (same as -c -sS)
-a, -all Search all sets (same as -s=ePpsSt)
Notes:
- Default version and architecture read from the OS (/etc/slackware-version
and uname -m). You can hardcode them in ~/.config/surfraw/conf (see below).
- Search modes: "package" looks at package names, "description"
looks at the .txt files named after the packages (created from the
slack-desc), "label" looks at the first line of .txt file, and "content"
looks at the contents of packages.
- "content" searches are for finding out which package a file belongs to.
Be aware that symlinks aren't found by this, although if the symlink
exists on the local system, its target will be used instead.
- The source search is basically useless without "content" mode. Actually
it's pretty useless anyway.
- Defaults can be set in the config file "~/.config/surfraw/conf". Example:
SURFRAW_slack_ver=14.2
SURFRAW_slack_arch=64
SURFRAW_slack_mode=package
SURFRAW_slack_sets=eps
For 32-bit architecture (i586), use:
SURFRAW_slack_arch=""
In other words do NOT set it to 32, the only valid values
are "64" and "".
