Obsidian Orgmode CM6

Orgmode for Obsidian.

Usage

By default org files are not shown in the sidebar. To display them you need to go into the obsidian settings, section Files and links and check Detect all file extensions.

To create an org file in your vault, you currently have to create it outside obsidian, as obsidian doesn't allow to create a non-markdown file.

If you don't already have an org file, try to create a file called todo.org with the following content:

* TODO [#A] A task with *high* priority

The description of the task

* A collapsed section

You cannot see the description when collapsed

* DONE something done already :sometag:
SCHEDULED: <2023-12-08 Fri 11:13>
:PROPERTIES:
:CREATED: [2023-12-03 Sun 10:48]
:END:

• Dynamic Block
• Drawer
• List and Checkbox

Implementation details

• The orgmode files are handled with a codemirror 6 instance which is separate from the one used by the markdown files. That means the plugin has to re-implement all features working for markdown files.

• The parser reads an orgmode file and builds a tree of syntax nodes by using a lezer grammar with custom tokenizers. This approach allows to match tokens more precisely than the regex-based approach of Emacs. For example, planning lines are only matched after a heading and not in the middle of a section.

• Overlapping tokens are not considered valid. Take for example: *one _two three* four_. Emacs, using regexes would have *one _two three* as bold and _two three* four_ as underline. The lezer parser is instead considering *one _two three* as bold and four_ as normal text, it makes it possible to have the text markup range as its own syntax node.

• There is no limits to the level of headings (so no Inlinetask) or the number of lines of a text markup.

Show orgmode tasks in markdown files

This feature is unstable and will likely change in breaking ways in the future.

Currently only TODO and DONE are handled.
