§1. Creation.

navigation_design *Unsigned::create?Usage of Unsigned::create:
Navigational Designs - §1(void) {
    navigation_design *ND = Nav::new(I"unsigned", TRUE, FALSE);
    METHOD_ADD(ND, RENDER_VOLUME_TITLE_MTID, Unsigned::unsigned_volume_title);
    METHOD_ADD(ND, RENDER_CHAPTER_TITLE_MTID, Unsigned::unsigned_chapter_title);
    METHOD_ADD(ND, RENDER_SECTION_TITLE_MTID, Unsigned::unsigned_section_title);
    METHOD_ADD(ND, RENDER_INDEX_TOP_MTID, Unsigned::unsigned_navigation_index_top);
    METHOD_ADD(ND, RENDER_NAV_MIDDLE_MTID, Unsigned::unsigned_navigation_middle);
    return ND;
}

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

void Unsigned::unsigned_volume_title?Usage of Unsigned::unsigned_volume_title:
§1(navigation_design *self, text_stream *OUT, volume *V) {
    Render a volume heading2.1;
    Render a chapter-contents table2.2;
}

§2.1. Render a volume heading2.1 =

    TEMPORARY_TEXT(partn)
    if (no_volumes > 1) Roadsign::roman_numeral(partn, V->allocation_id);
    HTML_OPEN_WITH("p", "class=\"volumeheading\"");
    WRITE("%S%S", partn, V->vol_title);
    HTML_CLOSE("p");

• This code is used in §2.

§2.2. Render a chapter-contents table2.2 =

    int nch = V->vol_chapter_count;
    for (int rc = 0; rc < nch; rc++) {
        chapter *C = V->chapters[rc];
        HTML_OPEN("p");
        HTML::begin_link_with_class(OUT, I"standardlink", C->chapter_URL);
        HTML_OPEN_WITH("span", "class=\"chapterlisting\"");
        WRITE("%S", C->chapter_full_title);
        HTML_CLOSE("span");
        HTML::end_link(OUT);
        HTML_CLOSE("p");
    }

• This code is used in §2.

§3.

void Unsigned::unsigned_chapter_title?Usage of Unsigned::unsigned_chapter_title:
§1(navigation_design *self, text_stream *OUT, volume *V, chapter *C) {
    Render a chapter heading3.1;
    Render a section-contents listing3.2;
}

§3.1. Render a chapter heading3.1 =

    HTML_OPEN_WITH("p", "class=\"chapterheading\"");
    if (Str::len(C->chapter_anchor) > 0) HTML::anchor(OUT, C->chapter_anchor);
    WRITE("%S", C->chapter_full_title);
    HTML_CLOSE("p");

• This code is used in §3.

§3.2. Render a section-contents listing3.2 =

    HTML_OPEN_WITH("p", "class=\"chaptercontents\"");
    int lcount = 0;
    for (section *S = V->sections[0]; S; S = S->next_section) {
        if (S->in_which_chapter == C) {
            if (lcount++ > 0) WRITE("; ");
            HTML::begin_link_with_class(OUT, I"standardlink", S->section_URL);
            HTML_OPEN_WITH("span", "class=\"chaptercontentsitem\"");
            WRITE("%c%S", SECTION_SYMBOL, S->title);
            HTML_CLOSE("span");
            HTML::end_link(OUT);
        }
    }
    HTML_CLOSE("p");

• This code is used in §3.

§4.

void Unsigned::unsigned_section_title?Usage of Unsigned::unsigned_section_title:
§1(navigation_design *self, text_stream *OUT, volume *V, chapter *C, section *S) {
    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");
}

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

void Unsigned::unsigned_navigation_index_top?Usage of Unsigned::unsigned_navigation_index_top:
§1(navigation_design *self, text_stream *OUT, text_stream *filename, text_stream *title) {
    HTMLUtilities::ruled_line(OUT);
}

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

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