Obsidian

When viewing longer Markdown notes in Obsidian, tables of content (TOC) help a lot with navigation. There is a handful of community plugins to help with TOC generation, but I have two issues with them:

1. It creates a dependency on code whose developer may lose interest and eventually abandon the project. At least one dynamic TOC plugin has suffered this fate.
2. All of the TOC plugins have the same visual result. When you navigate to a note, Obsidian places the focus at the top of the note, beneath the frontmatter. That’s fine unless the content starts with a TOC markup block, in which case it’s not the TOC itself that is displayed, but the markup for the TOC plugin itself as depicted in the image below.

For me the solution was to write a script that scans the vault looking for this pair of markers:

Obsidian is pretty reckless with file creation dates. If you modify a note in Obsidian, it updates the file creation date. This renders Dataview queries that rely on it useless. For an introduction to this issue, see this lengthy thread on the Obsidian forums.

Workarounds

There are a several solutions to this problem.

1. YAML-based dates

One can include a cdate (or similar) field in the note’s front matter and just direct the Dataview query against that, e.g. LIST FROM "" WHERE startswith(cdate,"2023-05-29") SORT file.ctime asc. This works, but of course it requires you to always place that field ahead of your note content. Some people like that; others not so much.

Although I’m a relative newcomer to Obsidian, I like what I see, especially the templating and data access functionality - both that provided natively and through the Templater and Dataview plugins.

One missing piece is the ability to dynamically update the YAML-formatted metadata in the frontmatter of Obsidian’s Markdown documents. Several threads on both the official support forums and on r/ObsidianMD have addressed this; and there seems to be no real solution.¹ None proposed solution - mainly view Dataview inline queries or Templater dynamic commands - seems to work consistently.

There are a couple features of the Dataview plugin for Obsidian that aren’t documented and are potentially useful.

For the start of the week, use date(sow) and for the end of the week date(eow). Since there’s no documentation as of yet, I’ll venture a guess that they are locale-dependendent. For me (in Canada), sow is Monday. Since I do my weekly notes on Saturday, I have to subtract a couple days to point to them.
