[NTG-context] issues with bookmarks

26 Jul 2015

      Hans,

sorry for the long message, but I’m afraid that bookmarks have some issues.

1. When specifying sectionblocks, bookmarks for parts don’t contain
chapters as child elements:

    \setupinteraction[state=start]
    \placebookmarks[part, chapter][part, chapter]
    \setuphead[part][placehead=yes]
    \starttext
    \startfrontmatter
    \chapter{Foreword}
    \chapter{Introduction}
    \stopfrontmatter
    \startbodymatter
    \part{First Part}
    \chapter{First Chapter}
    \chapter{Second Chapter}
    \part{Second Part}
    \chapter{Third Chapter}
    \chapter{Fourth Chapter}
    \stopbodymatter
    \stoptext

It isn’t related to parts and chapters, it also happens with chapters
and sections:

    \setupinteraction[state=start]
    \placebookmarks[chapter, section][chapter, section]
    \starttext
    \startfrontmatter
    \section{Foreword}
    \section{Introduction}
    \stopfrontmatter
    \startbodymatter
    \chapter{First chapter}
    \section{First section}
    \section{Second section}
    \chapter{Second chapter}
    \section{Third section}
    \section{Fourth section}
    \stopbodymatter
    \stoptext

It works fine, if sectionblocks are removed:

    \setupinteraction[state=start]
    \placebookmarks[part, chapter][part, chapter]
    \setuphead[part][placehead=yes]
    \starttext
    \chapter{Foreword}
    \chapter{Introduction}
    \part{First Part}
    \chapter{First Chapter}
    \chapter{Second Chapter}
    \part{Second Part}
    \chapter{Third Chapter}
    \chapter{Fourth Chapter}
    \stoptext

2. Sectionblocks also displace bookmark location, such as in this sample:

    \setupinteraction[state=start]
    \placebookmarks[part, chapter, hiddentitle][part, chapter]
    \setuphead[part][placehead=yes]
    \definehead
        [hiddentitle]
        [chapter]
    \setuphead
        [hiddentitle]
        [number=no]
    \starttext
    \hiddentitle{[Copyright]}
    \startfrontmatter
    \chapter{Foreword}
    \chapter{Introduction}
    \stopfrontmatter
    \startbodymatter
    \part{First Part}
    \chapter{First Chapter}
    \chapter{Second Chapter}
    \part{Second Part}
    \chapter{Third Chapter}
    \chapter{Fourth Chapter}
    \stopbodymatter
    \stoptext

Foreword and Introduction are listed after Fourth Chapter.

If sectionblocks are removed, bookmark listing is ordered right:

    \setupinteraction[state=start]
    \placebookmarks[part, chapter, hiddentitle][part, chapter]
    \setuphead[part][placehead=yes]
    \definehead
        [hiddentitle]
        [chapter]
    \setuphead
        [hiddentitle]
        [number=no]
    \starttext
    \hiddentitle{[Copyright]}
    \chapter{Foreword}
    \chapter{Introduction}
    \part{First Part}
    \chapter{First Chapter}
    \chapter{Second Chapter}
    \part{Second Part}
    \chapter{Third Chapter}
    \chapter{Fourth Chapter}
    \stoptext

3. In the previous sample, as well in the following one, bookmark
hierarchy is wrong:

    \setupinteraction[state=start]
    \placebookmarks[part, chapter, hiddentitle][part, chapter]
    \setuphead[part][placehead=yes]
    \definehead
        [hiddentitle]
        [chapter]
    \setuphead
        [hiddentitle]
        [number=no]
    \starttext
    \hiddentitle{[Copyright]}
    \startfrontmatter
    \chapter{Foreword}
    \chapter{Introduction}
    \stopfrontmatter
    \startbodymatter
    \part{First Part}
    \chapter{First Chapter}
    \chapter{Second Chapter}
    \part{Second Part}
    \chapter{Third Chapter}
    \chapter{Fourth Chapter}
    \stopbodymatter
    \startbackmatter
    \chapter{Conclusions}
    \chapter{Epilogue}
    \stopbackmatter
    \stoptext

I’m afraid that (the misplaced Foreword or Introduction and) Conclusions
and Epilogue should be first-level bookmarks (such as Copyright is).

After a sectionblock, chapters should have first-level bookmarks if
there is no part bookmark containing them. Otherwise, this will be the
misleading impression that the chapters are children of the part bookmark.

Am I missing something or have I hit a bug?

Many thanks for your help,

Pablo
