The "architect" style of navigational gadgets.

• §1. Creation
• §2. Top
• §3. Index top
• §4. Middle
• §5. Bottom
• §6. Banners
• §8. Contents page

§1. Creation. Architect doesn't have volume or chapter titles as such, since the banner heading includes these anyway.

navigation_design *Architect::create?Usage of Architect::create:
Navigational Designs - §1(void) {
    navigation_design *ND = Nav::new(I"architect", FALSE, FALSE);
    ND->columnar = TRUE;
    ND->contents_body_class = I"paper architectpapertint";
    METHOD_ADD(ND, RENDER_SECTION_TITLE_MTID, Architect::architect_section_title);
    METHOD_ADD(ND, RENDER_INDEX_TOP_MTID, Architect::architect_navigation_index_top);
    METHOD_ADD(ND, RENDER_NAV_MIDDLE_MTID, Architect::architect_navigation_middle);
    METHOD_ADD(ND, RENDER_NAV_BOTTOM_MTID, Architect::architect_navigation_bottom);
    METHOD_ADD(ND, RENDER_CONTENTS_MTID, Architect::architect_navigation_contents_files);
    METHOD_ADD(ND, RENDER_CONTENTS_HEADING_MTID, Architect::architect_navigation_contents_heading);
    return ND;
}

§2. Top. At the front end of a section, before any of its text.

void Architect::architect_section_title?Usage of Architect::architect_section_title:
§1(navigation_design *self, text_stream *OUT, volume *V, chapter *C, section *S) {
    if (S->begins_which_chapter == NULL) {
        TEMPORARY_TEXT(comment)
        WRITE_TO(comment, "START IGNORE %d", S->number_within_volume);
        HTML::comment(OUT, comment);
        DISCARD_TEXT(comment)
    }
    HTML::begin_div_with_class_S(OUT, I"bookheader", __FILE__, __LINE__);
    text_stream *linkleft = NULL;
    text_stream *linkright = NULL;
    Work out URLs for the preceding and following sections2.1;
    TEMPORARY_TEXT(leaf)
    WRITE_TO(leaf, "%S.html", indoc_settings->contents_leafname);
    Architect::architect_banner(OUT,
        S->in_which_chapter->chapter_full_title, V, leaf, linkleft, linkright);
    HTML::end_div(OUT);
    if (S->begins_which_chapter == NULL) HTML::comment(OUT, I"END IGNORE");

    HTML_OPEN_WITH("p", "class=\"sectionheading\"");
    if (Str::len(S->section_anchor) > 0) HTML::anchor(OUT, S->section_anchor);
    WRITE("%c%S", SECTION_SYMBOL, S->title);
    HTML_CLOSE("p");
}

§2.1. Work out URLs for the preceding and following sections2.1 =

    if (S->previous_section) linkleft = S->previous_section->section_URL;
    if (S->next_section) linkright = S->next_section->section_URL;

• This code is used in §2.

§3. Index top. And this is a variant for index pages, such as the index of examples.

void Architect::architect_navigation_index_top?Usage of Architect::architect_navigation_index_top:
§1(navigation_design *self, text_stream *OUT, text_stream *filename, text_stream *title) {
    Architect::architect_banner(OUT, title, 0, NULL, NULL, NULL);
}

§4. Middle. At the middle part, when the text is over, but before any example cues.

void Architect::architect_navigation_middle?Usage of Architect::architect_navigation_middle:
§1(navigation_design *self, text_stream *OUT, volume *V, section *S) {
    HTMLUtilities::ruled_line(OUT);
}

§5. Bottom. At the end of the section, after any example cues and perhaps also example bodied. (In a section with no examples, this immediately follows the middle.)

void Architect::architect_navigation_bottom?Usage of Architect::architect_navigation_bottom:
§1(navigation_design *self, text_stream *OUT, volume *V, section *S) {
    HTML::begin_div_with_class_S(OUT, I"bookfooter", __FILE__, __LINE__);
    HTML_OPEN_WITH("table", "class=\"fullwidth\"");
    HTML_OPEN("tr");
    HTML_OPEN_WITH("td", "class=\"footerprevious\"");
    if (S->previous_section)
        HTMLUtilities::general_link(OUT, I"footerlink", S->previous_section->section_URL, I"Previous");
    HTML_CLOSE("td");
    HTML_OPEN_WITH("td", "class=\"footercontents\"");
    TEMPORARY_TEXT(url)
    WRITE_TO(url, "%S.html", indoc_settings->contents_leafname);
    HTMLUtilities::general_link(OUT, I"footerlink", url, I"Contents");
    DISCARD_TEXT(url)
    HTML_CLOSE("td");
    HTML_OPEN_WITH("td", "class=\"footernext\"");
    if (S->next_section)
        HTMLUtilities::general_link(OUT, I"footerlink", S->next_section->section_URL, I"Next");
    else {
        HTML_OPEN_WITH("span", "class=\"footernonlink\"");
        WRITE("End");
        HTML_CLOSE("span");
    }
    HTML_CLOSE("td");
    HTML_CLOSE("tr");
    HTML_CLOSE("table");
    HTML::end_div(OUT);
}

§6. Banners. These are the black, status-line-like banners with navigation icons at the top of every Architect page.

void Architect::architect_banner?Usage of Architect::architect_banner:
§2, §3(text_stream *OUT, text_stream *title, volume *V,
    text_stream *linkcentre, text_stream *linkleft, text_stream *linkright) {
    HTML_OPEN_WITH("table", "class=\"fullwidth midnightblack\"");
    HTML_OPEN("tr");
    HTML_OPEN_WITH("td", "class=\"midnightbannerleftcell\"");
    if (Str::len(linkleft) > 0) {
        TEMPORARY_TEXT(img)
        HTMLUtilities::image_with_id(img, I"Hookleft.png", I"hookleft");
        HTMLUtilities::general_link(OUT, I"standardlink", linkleft, img);
        DISCARD_TEXT(img)
    }
    HTML_CLOSE("td");
    HTML_OPEN_WITH("td", "class=\"midnightbannercentrecell\"");
    if (Str::len(linkcentre) > 0) {
        TEMPORARY_TEXT(url)
        WRITE_TO(url, "%S.html", indoc_settings->contents_leafname);
        HTML::begin_link_with_class(OUT, I"standardlink", url);
        DISCARD_TEXT(url)
    }
    HTML_OPEN_WITH("span", "class=\"midnightbannertext\"");
    WRITE("%S", title);
    HTML_CLOSE("span");
    if (Str::len(linkcentre) > 0)
        HTML::end_link(OUT);
    HTML_CLOSE("td");
    HTML_OPEN_WITH("td", "class=\"midnightbannerrightcell\"");
    TEMPORARY_TEXT(url)
    TEMPORARY_TEXT(img)
    WRITE_TO(url, "%S.html", indoc_settings->contents_leafname);
    HTMLUtilities::image_with_id(img, I"Hookup.png", I"hookup");
    HTMLUtilities::general_link(OUT, I"standardlink", url, img);
    DISCARD_TEXT(img)
    DISCARD_TEXT(url)
    if (Str::len(linkright) > 0) {
        TEMPORARY_TEXT(img)
        HTMLUtilities::image_with_id(img, I"Hookright.png", I"hookright");
        HTMLUtilities::general_link(OUT, I"standardlink", linkright, img);
        DISCARD_TEXT(img)
    }
    HTML_CLOSE("td");
    HTML_CLOSE("tr");
    HTML_CLOSE("table");
}

§7. And this is a similar design motif used in Architect contents pages: see below.

void Architect::architect_contents_column_banner(OUTPUT_STREAM,
    text_stream *title, volume *V, text_stream *extra) {
    HTML_OPEN_WITH("table", "class=\"fullwidth midnightblack\"");
    HTML_OPEN("tr");
    HTML_OPEN_WITH("td", "class=\"midnightbannerleftcell\"");
    WRITE("%S", extra);
    HTML_CLOSE("td");
    HTML_OPEN_WITH("td", "class=\"midnightbannercentrecell\"");
    HTML_OPEN_WITH("span", "class=\"midnightbannertext\"");
    WRITE("%S", title);
    HTML_CLOSE("span");
    HTML_CLOSE("td");
    HTML_CLOSE("tr");
    HTML_CLOSE("table");
}

§8. Contents page. Architect provides a contents page of its very own.

void Architect::architect_navigation_contents_files?Usage of Architect::architect_navigation_contents_files:
§1(navigation_design *self) {
    Midnight::write_contents_page(self, volumes[0]);
}

void Architect::architect_navigation_contents_heading?Usage of Architect::architect_navigation_contents_heading:
§1(navigation_design *self, text_stream *OUT, volume *V) {
    WRITE("\n\n");
    HTML_OPEN_WITH("table", "cellspacing=\"3\" border=\"0\" width=\"100%%\"");
    HTML_OPEN("tr");
    HTML_OPEN_WITH("td", "style=\"width:80px; height:120px;\"");
    HTML_TAG_WITH("img", "src=\"inform:/doc_images/wwi_cover@2x.png\" class=\"thinbordered\" style=\"width:80px; height:120px;\"");
    HTML_CLOSE("td");
    HTML_OPEN_WITH("td", "style=\"width:80px; height:120px;\"");
    HTML_TAG_WITH("img", "src=\"inform:/doc_images/irb_cover@2x.png\" class=\"thinbordered\" style=\"width:80px; height:120px;\"");
    HTML_CLOSE("td");
    HTML_OPEN_WITH("td", "style=\"width:100%%;\"");
    HTML_OPEN_WITH("div", "class=\"headingboxhigh\"");
    HTML_OPEN_WITH("div", "class=\"headingtext\"");
    WRITE("Documentation");
    HTML_CLOSE("div");
    HTML_OPEN_WITH("div", "class=\"headingrubric\"");
    WRITE("Two complete books about Inform:");
    HTML_TAG("br");
    WRITE("<i>Writing with Inform</i>, a comprehensive introduction");
    HTML_TAG("br");
    WRITE("<i>The Inform Recipe Book</i>, practical solutions for authors to use");
    HTML_CLOSE("div");
    HTML_CLOSE("div");
    HTML_CLOSE("td");
    HTML_CLOSE("tr");
    HTML_CLOSE("table");
    HTML_OPEN_WITH("table", "class=\"fullwidtharch\"");
    HTML_OPEN("tr");
}
