## Introduction to customising the appearance of a Greenstone Collection.
##
## You will need to know some basic HTML coding to edit this file.
##
## This file overrides some of the default macros used by greenstone. I've
## tried to explain what each custom macro does, so hopefully it is
## straight-forward. I'm sure it looks a little daunting at first, but the
## use of macros gives you lots of flexibility for modifying pages, once
## you get the hang of it.

## General comments and hints

## In these macro files, the '#' is the start of a comment. Greenstone will
## ignore everything after a '#' until the end of the line, unless it
## is part of a macro.

## To change the appearance of your Greenstone library, edit the macro files 
## in greenstone/macros. If you need to add a new macro file, you must add it 
## to the "macrofiles" list in greenstone/etc/main.cfg so that Greenstone 
## will use it.

## To change the appearance of just a single collection, create a file 
## called extra.dm in the macros directory of the collection.  Collection 
## specific macros should be put in there. Macros in this file will override 
## the default greenstone macros, just for that collection.

## Every page action in greenstone has a name. We call it a "package".
## So the default action is the "about" package. (This is the p=about cgi
## argument). Other common actions are "document" and "help".
## If a macro isn't found that is specific to that action, then greenstone
## will fall back to macros defined in the "Global" package.
## All macros in this file belong to whichever package was the most recently
## mentioned one, with a line such as "package Global".

## macros can have optional parameters, that make them more specific.
## For example, you could have _macro_ {general case} as well as
## _macro_ [c=garish-e] {For garish-e collection only} for when the 
# "c" argument (which means the collection) is set to "garish-e". 
## Or _macro_ [l=fr] {french case} for 
## when the language is set to French. This is how we cope with different 
## language interfaces.

## Collection specific macros put into the main macro files must have a 
## collection parameter ([c=garish-e]), otherwise they will apply to all 
## collections. Macros in a collection's extra.dm do not need this parameter.

## Don't refer to a macro's name inside the same macro, otherwise greenstone
## will go into a recursive loop printing out the macro...

## I've put HTML comments like <!-- end of custom header --> in the macros
## so that you can see them when you do "view source" on a web page, to
## help see the effect of changes of these macros.

## _httpcimages_ is a macro that expands to the images directory of the 
## current collection. Any collection images or stylesheets should be put 
## there. 

## The macros below modify the appearance of a specific greenstone collection.
## It makes all the pages include a style-sheet, so that you can put
## html-related appearance stuff (such as font colours and faces) in there,
## rather than editing the macros for each piece of text.
## mozilla has excellent CSS support - Netscape 4 and IE both have
## incomplete implementations, but mostly work with the simple CSS I've used
## here as a demonstration.
##
## Edit the file garish-e/styles/style.css to change the colours and fonts.


##############################################################################
package Global
##############################################################################
## default macros - can be overridden by specific packages. The normal versions
## of these macros are in the file base.dm (and in the language-specific
## macro files such as english.dm and french.dm)

## These 2 macros are used for highlighting text that matched a query when
## displaying a document. The default is to set the background to yellow.
##
## Note - this is a joke. Please don't ever use the blink tag in real life :)
#_starthighlight_  {<blink>}
#_endhighlight_  {</blink>}

_starthighlight_ {<b>}
_endhighlight_ {</b>}

## navbarspacer - this is what goes between the search button and the
## classifier buttons in the navigation bar.  The default is the
## horizontal green bar.  You can put any html in here, and you can use
## the _widthtspace_ macro if you want the calculated gap between the
## buttons.
## Note, navigation bar macros are defined in nav_css.dm, not base.dm

## Note - netscape 4.x needs a space between the br and the /
#_navbarspacer_  {<br />}

## If you don't like the look of that, you could comment the above line out
## and uncomment one of the following definitions for navbarspacer:

## This will stack the buttons one above the other (they are in a table) with
## our image as separator. This closes the current row and starts a new one.
## This will use our custom image in the collection's images directory.

_navbarspacer_  { 
<br /><img src="_httpcimages_/horzline.gif" width="87" height="17">
<br />
}

## This uses our custom image instead of the green bar, but otherwise has the
## buttons horizontally, just like the default.
#
#_navbarspacer_  {
# <img src="_httpcimages_/horzline.gif" width="_widthtspace_"
# height="17"> 
#}


##############################################################################
package Style
##############################################################################

## Style package is responsible for creating the header and footer of every
## page. This is special as there is no style action as such - the other
## actions include macros from here.

## htmlhead is used by the default _header_ macros. It prints out the
## beginning of an html file, including the header. It includes the 
## _cssheader_ macro, which links to external stylesheets, and includes 
## some image declarations. To override the entire style, write a new 
## _cssheader_ macro here

#_cssheader_ {
#<link rel="stylesheet" href="_httpcstyles_/style.css" type="text/css" 
#   title="Garish style Style" charset="UTF-8">
#}

## To keep most of the standard greenstone style, and just override a few 
## style declarations, we can define _collectionspecificstyle_, which is 
## included in the default _cssheader_ macro. The title of a stylesheet 
## link must be 'Greenstone Style', in order for it to be used in 
## conjunction with the main stylesheet.

## Here we include the garish-e collection's stylesheet, which defines the 
## page color to pink.
## We also remove the background image for the page to get rid of the green 
## swirly bar, and specify a new (blue) background image for hover 
## (mouse over) on the navigation bar buttons 

_collectionspecificstyle_ {
<link rel="stylesheet" href="_httpcstyles_/style.css" type="text/css" 
   title="Greenstone Style" charset="UTF-8">
<style>
body.bgimage \{ background-image: none; \}
a.navlink:hover \{ background-image: url("_httpcimages_/bg_blue.gif"); \}
</style>

}

## The default _pagebanner_ includes the collection's logo, the
## home/help/preferences buttons, and a large image that says whether
## you're viewing the about page, the search page, the titles page, etc.

## Uncomment this or define style:pagebanner to something else if you don't
## want any of those images appearing

## Remove banner entirely
#_pagebanner_ {}

## Just leave in the home button
_pagebanner_  {
<div id="banner">
<div class="pageinfo"> 
<p class="bannerlinks">_homelink_</p>
</div>
</div>
}

##############################################################################
package about
##############################################################################
## "about" is page you see when you first go to a collection. The default
## versions of these macros are in the about.dm file.

## content by default has the navigationbar (links to Search and classifiers),
## and "About this collection" and "how to find information" text.
## The _navigationbar_ macro is defined internally by the greenstone server,
## and uses the _imagespacer_ macro defined in the Global section.
##
## This is similar to the default, except that we don't center the navigation 
## bar and don't include a search box on the collection's about page.


_content_  {
<!-- start of custom about:content -->
_navigationbar_
<div class="document">
_textabout_

<div class="section">
<h3>_help:textsimplehelpheading_</h3>
_help:simplehelp_
</div>
</div>
<!-- end of custom about:content -->
}


##############################################################################
package query
##############################################################################
## These are macros related to creating the search page. The default versions
## are in the file query.dm


## This is similar to the default, except we don't centre the _navigationbar_
## and we've removed one of the green bars
_content_  {
<!-- start of custom query:content -->
_navigationbar_

<div class="document">
<div class="queryform">
<center>
_If_(_cgiargct_,_selectqueryform_,_queryform_)
</center>
</div>
_If_(_searchhistorylist_,<center>_iconsearchhistorybar_</center><br />
<center>
_searchhistorylist_
</center>)
_If_(_cgiargq_,<small>_freqmsg_ _textpostprocess_</small><br />_resultline_,)
<br />
<!-- end of custom query:content -->
}


##############################################################################
package document
##############################################################################
## These are macros related to creating a document page. The default versions
## are in the file document.dm. Note that technically, the classifiers are
## also document pages (eg the title lists).

## Note that the server overrides the _header_ macro if we are "not at the
## top level", which basically means that when viewing a document (and not
## a classifier), there won't be a heading.
##
## We can get around this by re-defining the textheader macro to output
## what we want (instead of the normal version in document.dm). We copy the 
## Global version of _header_ (from style.dm) and add it as the content of
## _textheader_. Note that we can't just use 
## _textheader_  {_Global:header_}
## as any package specific macros (eg _pagetitle_) will no longer be used.

_textheader_  {
_cgihead_
_htmlhead_(class="bgimage")_startspacer__pagebanner_
}


## Override the default so that we are not centering the navigation bar.
## The library will automatically output the document after this.
_content_  {
<!-- start of custom document:content -->
_navigationbar_

_If_(_phindclassifier__collageclassifier_,
<p style="text-align: center;">
_phindclassifier_
_collageclassifier_
</p>
)

_If_("_cgiargcl_" eq "search",
<ul id="searchresults">
_prevsearchresult_
_nextsearchresult_
</ul>)

<div class="document">
<!-- end of custom document:content -->
}
