v0.8.0

Added

• Preset.convertOrg(org, convert) and
  Preset.convertMarkdown(markdown, convert), optional hooks that take
  a whole conversion over, for a dialect whose documents are an outline
  of fragments; convert runs the core on one fragment (recording no
  Markdown style: a fragment's style is the preset's).
• The Web UI demo also shows a quote, a nested ordered list and a src
  block switch.
• The Web UI offers a Logseq demo page, in Logseq org or Logseq
  Markdown, while the Logseq preset is selected; an untouched demo
  follows the preset as it follows the direction.

Changed

• Breaking. Logseq preset: a page converts as Logseq's outline of
  blocks. Org headlines ↔ - bullets indented one tab per level, an
  empty block (bare stars) ↔ -, :heading: N ↔ - ## …, a block's
  property drawer ↔ key:: value lines; a block's content converts as
  one fragment, so a code block or table that starts on the headline
  line stays whole. Blocks used to become paragraphs below the nearest
  heading, which flattened every level below it. logseq() takes no
  options anymore (nestUnderHeadings is gone).

Fixed

• A src block's switches and header arguments
  (#+begin_src python -n :results output) travel as the Markdown
  fence's meta (```python -n :results output) instead of being
  dropped both ways.
• A block or drawer kept as org text in Markdown (special, verse,
  center blocks, :LOGBOOK:, …) no longer falls apart on the way back
  when its lines read as Markdown syntax: a blank line followed by an
  indented line became a code block, a # line a heading, a - line a
  list, and
  the round trip did not converge.
• Logseq preset: a block whose content starts with its properties
  (** :PROPERTIES:, as Logseq writes a query block) keeps them as its
  key:: lines instead of growing an :END: line per round trip.
• Logseq preset: a repeated task's :LOGBOOK: state lines take the
  bullet Logseq writes in each format, - State … in org and
  * State … in Markdown.
• Logseq preset: an org plain link (https://…) stays a bare url in
  Markdown, as Logseq writes it, and comes back plain instead of as
  [[https://…]].
• Logseq preset: an email address stays text, written bare in
  Markdown as Logseq does, instead of coming back as a mailto: link.
• Logseq preset: a block that starts with a tag (#meeting) keeps it
  a tag in Markdown; it was written \#meeting, which Logseq reads as
  plain text.
• Logseq preset: an org block written in a Markdown block
  (#+BEGIN_SRC…#+END_SRC, which Logseq reads there too) goes to org
  instead of as escaped text that changed on every round trip; the
  Markdown content of a quote block converts.
