Previously only autogenerated ids were added to the list of header identifiers in state, so explicit ids weren't taken into account when generating unique identifiers. Duplicated identifiers could result. This simple fix ensures that explicitly given identifiers are also taken into account. Fixes #1745. Note some limitations, however. An autogenerated identifier may still coincide with an explicit identifier that is given for a header later in the document, or with an identifier on a div, span, link, or image. Fixing this would be much more difficult, because we need to run `registerHeader` before we have the complete parse tree (so we can't get a complete list of identifiers from the document by walking the tree). However, it might be worth issuing warnings for duplicate header identifiers; I think we can do that. It is not common for headers to have the same text, and the issue can always be worked around by adding explicit identifiers, if the user is aware of it. |

Pandoc
The universal markup converter
Pandoc is a Haskell library for converting from one markup format to
another, and a command-line tool that uses this library. It can read
Markdown, CommonMark, PHP Markdown Extra, GitHub-Flavored Markdown,
MultiMarkdown, and (subsets of) Textile, reStructuredText, HTML,
LaTeX, MediaWiki markup, TWiki markup, Haddock markup, OPML, Emacs
Org mode, DocBook, txt2tags, EPUB, ODT and Word docx; and it can
write plain text, Markdown, CommonMark, PHP Markdown Extra,
GitHub-Flavored Markdown, MultiMarkdown, reStructuredText, XHTML,
HTML5, LaTeX including [`beamer`] slide shows, ConTeXt, RTF, OPML,
DocBook, OpenDocument, ODT, Word docx, GNU Texinfo, MediaWiki
markup, DokuWiki markup, ZimWiki markup, Haddock markup,
EPUB v2 or v3, FictionBook2, Textile, groff man pages,
Emacs Org mode, AsciiDoc, InDesign ICML, TEI Simple, Muse, and Slidy,
Slideous, DZSlides, reveal.js or S5 HTML slide shows. It can also
produce PDF output on systems where LaTeX, ConTeXt, or wkhtmltopdf is
installed.
Pandoc's enhanced version of Markdown includes syntax for footnotes,
tables, flexible ordered lists, definition lists, fenced code blocks,
superscripts and subscripts, strikeout, metadata blocks, automatic tables of
contents, embedded LaTeX math, citations, and Markdown inside HTML block
elements. (These enhancements, described
further under Pandoc's Markdown, can be disabled using the
markdown_strict input or output format.)
In contrast to most existing tools for converting Markdown to HTML, which use regex substitutions, pandoc has a modular design: it consists of a set of readers, which parse text in a given format and produce a native representation of the document, and a set of writers, which convert this native representation into a target format. Thus, adding an input or output format requires only adding a reader or writer.
Because pandoc's intermediate representation of a document is less expressive than many of the formats it converts between, one should not expect perfect conversions between every format and every other. Pandoc attempts to preserve the structural elements of a document, but not formatting details such as margin size. And some document elements, such as complex tables, may not fit into pandoc's simple document model. While conversions from pandoc's Markdown to all formats aspire to be perfect, conversions from formats more expressive than pandoc's Markdown can be expected to be lossy.
