OK, I cleaned it up a lot! There were lots of changes between 3.1.3
and 3.1.6, so it took quite a bit longer than I thought it would to
get this adapted and working on 3.1.6. But, I did it. I also removed
some of the superfluous stuff like the "search policy" additions and the
whole collection_names attribute which seemed to cause too much confusion
(build_select_lists does a better job of generating the followup config
file list than collection_names did). I also put it a hook to get rid
of duplicate URLs, which happens if the same URL winds up in two or
more collections. (I'll have to port this to 3.2 as well!)
So, here is the patch for 3.1.6 below. Apply it in your main htdig-3.1.6
source directory using "patch -p0 < this-message". The patch is designed
to be applied after you've already run "./configure" in the source.
To enable it, #define COLLECTIONS in include/htconfig.h (this patch does
that by default, but it gets undone after another run of ./configure).
To use it, set up a number of config files in your CONFIG_DIR, and have
them all begin with "include: htdig.conf" (or some other common config
file, in which you'll have all your attribute settings). In each of
these config files, after the include above, override the settings of
database_dir (or database_base) and start_url, so that each config file
defines a separate database for a different collection of indexed URLs.
htsearch ends up using all of the display customization attributes from
the last selected config file, so for the sake of consistency, the config
files should share a common set of htsearch attributes.
To set up your initial search form, replace the "hidden" input parameter
definition for "config" with something like:
Collections:
<input type="checkbox" name="config" value="scrc" checked>SCRC Pages
<input type="checkbox" name="config" value="physiology">Physiology Pages
<input type="checkbox" name="config" value="wcsn">Winnipeg Chapter SFN Pages
<br>
and in the followup search forms (in header.html, wrapper.html, nomatch.html
and syntax.html), replace it with...
Collections:
$(CONFIG_LIST)<br>
which would be generated by these attribute settings in htdig.conf:
build_select_lists: CONFIG_LIST,checkbox config config_names 2 1 2 "" ""
config_names: scrc "SCRC Pages" physiology "Physiology Pages" \
wcsn "Winnipeg Chapter SFN Pages"
Here's the patch...
