markdown-modern 2.1.0

This release needs no setup changes. It adds a Mermaid diagram viewer, local file links and reference links, and fixes nested lists.

Thanks to Hemant Kumar (@gnufied) for local file links and two fixes, and to Samuel Michael Vanie (@SamuelVanie) for the Mermaid work.

• Click a Mermaid diagram, or press C-c C-v d in its source, to open it in a viewer. You can zoom and pan there.
• Mermaid flowcharts, sequence, state, class and ER diagrams draw more correctly. A diagram with a feature the renderer cannot draw, such as a subgraph, shows its source instead of a partial diagram.
• Local links open files in Emacs, relative to the Markdown file. #L352 and #L352-L365 go to that line. M-, goes back.
• Reference links render: [text][label], [text][] and [label]. Definition lines are dimmed.
• Nested list items show their bullet, number or checkbox again. Since 2.0.0 only the first level had one.
• Fix bold italic text that disappeared, line breaks next to inline code, and wrapped list text that did not line up.
• Fix C-c ' opening an empty buffer, and a link click that showed the link's markup first.
• Check all 313 tests on Emacs 30.1 and 31.1.

Download the tarball below and install it with M-x package-install-file, or follow the README.

To return to the previous release, install the package from tag 2.0.0.

markdown-modern 2.0.0

This release requires Tree-sitter. After upgrading, run M-x markdown-modern-install-grammars once and remove any markdown-modern-ts--use-tree-sitter setting from your init file.

• Require Tree-sitter for editing and rendering. The regex fallback is gone.
• Add M-x markdown-modern-install-grammars. It builds version 0.4.1 of both Markdown grammars, which also works with Tree-sitter libraries older than 0.25.
• Show source newlines inside a paragraph as spaces, so text fills the window width. A paragraph you edit shows its real lines, with a ↵ where they will join. Hard breaks stay. Set markdown-modern-join-paragraph-lines to nil to keep lines as written, in general or for one file.
• TAB in the last cell of a table adds a new row. TAB and S-TAB now stop in empty cells.
• Fix code-block editing so abort restores the original text.
• Check all 214 tests on Emacs 30.1 and 31.1. CI also tests the newest upstream grammars every month.

You need Git and a C compiler to build the grammars. On Windows, the README explains how to get a compiler.

markdown-modern 1.1.0

Tables stay rendered while you edit, with the active row kept aligned to the rest of the grid. Wide cells wrap to fit the window.

• Reveal list, blockquote and heading markers at point. Toggle task checkboxes with Space and remove them with Backspace or Delete.
• Fix tree-sitter rendering and reveal behavior on Emacs 31.
• Check all 242 tests on Emacs 30.1 and 31.1. CI also checks the regex fallback and runs monthly.
• Build versioned tarballs, check fresh installs and fail on compilation or package-lint errors.
• Add tree-sitter setup instructions, a refreshed screenshot and a MELPA recipe build command.
