Change the order or content of the navigation links

To override the order or content of the navigation module, override this function with the following (note the comments, some options should be removed or changed for unpaid accounts or communities). 

# code by ninetydegrees
function print_module_navlinks() {
 
  var Page p = get_page();
  var string[] navlinks_order = [];
  var string{} navlinks_urls = {};
  var string{} navlinks_text = {};
 
  $navlinks_order =
    [
        "recent",
        "archive",
        "read",
        # remove this for unpaid journals
        "network",
        "tags",
        "memories",
        # remove these if you don't want to add custom links
        "custom1",
        "custom2",
        "userinfo",
    ];
 
 $navlinks_urls =
    {
        "recent" => "$p.base_url/",
        "archive" => "$p.base_url/archive",
        "read" => "$p.base_url/read",
        "network" => "$p.base_url/network",
        "tags" => "$p.base_url/tag",
        "memories" => "$*SITEROOT/tools/memories?user=$p.journal.username",
        "custom1" => "http://URL",
        "custom2" => "http://URL",
        "userinfo" => "$p.base_url/profile",
    };
 
 $navlinks_text =
    {
        "recent" => "$*text_view_recent",
        "archive" => "$*text_view_archive",
        # use $*text_view_friends_comm for communities
        "read" => "$*text_view_friends",
        "network" => "$*text_view_network",
        "tags" => "$*text_view_tags",
        "memories" => "$*text_view_memories",
        "custom1" => "Custom Text",
        "custom2" => "Custom Text",
        "userinfo" => "$*text_view_userinfo",
    };
 
    open_module("navlinks", "", "");
    var string[] links = [];
    foreach var string k ($navlinks_order) {
        if ($navlinks_urls{$k} != "") {
            var string css = """ class="$k" """;
            if ($p.view == $k) { $css = """ class="current $k" """; }
            $links[size $links] = """<a href="$navlinks_urls{$k}"$css>$navlinks_text{$k}</a>""";
        }
    }
    print_module_list($links);
    close_module();
}

Add previous/next links to navigation links on pages

The following navlinks override checks to see if the page is an entry/day/recent/month page; if it is, it adds previous and next links to the beginning and end of the list of links. 

layerinfo "type" = "theme";

        var EntryPage ep = get_page() as EntryPage;
        var Entry e = $ep.entry;
        var Link prev = $e->get_link("nav_prev");
        $prev_link = """<a href="$prev.url">$prev.caption</a>""";
        var Link next = $e->get_link("nav_next");
        $next_link = """<a href="$next.url">$next.caption</a>""";
    } elseif ( $p isa DayPage ) {
        var DayPage dp = get_page() as DayPage;
        $prev_link = """<a href="$dp.prev_url">$*text_day_prev</a>""";
        $next_link = """<a href="$dp.next_url">$*text_day_next</a>""";
    } elseif ( $p isa RecentPage ) {
        var RecentPage rp = get_page() as RecentPage;
        if ( $rp.nav.backward_count > 0 ) { 
            $prev_link = """<a href="$rp.nav.backward_url">""" + get_plural_phrase( $rp.nav.backward_count, "text_skiplinks_back" ) + "</a>"; 
        }

            $next_link = """<a href="$rp.nav.forward_url">""" + get_plural_phrase( $rp.nav.forward_count, "text_skiplinks_forward" ) + "</a>"; 
        }
    } elseif ( $p isa MonthPage ) {
        var MonthPage mp = get_page() as MonthPage;
    	if ($mp.prev_url != "") { $prev_link = "<a href='$mp.prev_url'>Previous</a>"; }
    	if ($mp.next_url != "") { $next_link = "<a href='$mp.next_url'>Next</a>"; }
    }
 
    open_module("navlinks", "", "");
 
    if ( $apply_class_to_link ) {
        var string[] links = [];
 
        if ( $prev_link ) {
            $links[size $links] = $prev_link;
        }
 
        foreach var string k ($p.views_order) {
            var string css = """ class="$k" """;
            if ($p.view == $k) { $css = """ class="current $k" """; }
            $links[size $links] = """<a href="$p.view_url{$k}"$css>"""+lang_viewname($k)+"""</a>""";
 
        }
 
        if ( $next_link ) {
            $links[size $links] = $next_link;
        }
 
        print_module_list($links);
    } else {
        var string{}[] links = [];
 
        if ( $prev_link ) {
            $links[size $links] = { "class" => "previous", "item" => $prev_link };
        }
 
        foreach var string k ($p.views_order) {
            var string class = $k;
            if ($p.view == $k) { $class = "current $k"; }
            $links[size $links] = { "class" => $class, "item" => """<a href="$p.view_url{$k}">"""+lang_viewname($k)+"""</a>""" };
        }

        }
 
        print_module_list($links);
