Getting Started with Roam42 Smart Blocks with Brandon Toner

Smart Blocks turn Roam42 into a template-driven automation layer—letting users trigger workflows with a simple double-semicolon and then run actions like inserting dates, jumping to related blocks, or pulling in content—without needing separate browser extensions. The practical payoff is tighter daily workflows and easier sharing of repeatable processes across devices, since Smart Blocks are built to run as Roam/JS expansions.

Brandon Toner, a pharmacist in Nova Scotia, describes using Roam for “everything,” but emphasizes a key mental discipline: Roam can easily drift into scattered, divergent thinking if users don’t intentionally manage convergence. His approach is to alternate exploration with self-checks—if notes become too broad or expansive, he constrains attention and reshapes the system. That same philosophy carries into Smart Blocks: start simple, iterate, and adjust the workflow as real usage reveals what’s missing.

Smart Blocks themselves are extensions built by Chris for Roam42 that populate a template engine. At their core they’re “mostly around expansions,” but they include Roam-aware commands that can execute actions during expansion—such as calculating dates, creating links, or grabbing information from the web. Toner compares the value to TextExpander: Smart Blocks can replace the need to install and configure text-expansion tools on every device because they live inside Roam and run wherever Roam runs.

A central example is a Daily Page workflow. Toner triggers a Smart Block from the Daily Page using “two semicolons,” then selects a template (like a morning journal). The template can automatically stamp the time in AM/PM format, create a “date yesterday” jump link, pull in block references (e.g., from a prompts library), and generate tasks that connect back to prior-day work. Block references can be copied directly as IDs, or Smart Blocks can fetch them depending on the template design.

Beyond filling in templates, Smart Blocks introduce a query-like capability through commands such as “block mentions,” which returns blocks that mention a page reference with optional filtering. This enables a more guided Daily Page: instead of manually searching, the template can embed tasks scheduled for today, show them with direct editability, and limit how many results appear. Toner also experiments with “controlled randomization,” using tags (like Seedlings, Fleeting notes, or Evergreen categories) so random picks stay meaningful rather than returning irrelevant blocks.

Smart Blocks also point toward integrations and community-driven expansion. They’re JavaScript-enabled, and examples live in a public repository (including “spark blocks” labeled examples). Demonstrations include fetching a random quote from a site, adding a Wikipedia extract to a page, and syncing Todoist tasks into Roam. The broader vision is “algorithms of thought”: encoding repeatable thinking processes—question sequences, branching prompts, and convergence steps—while keeping an “exit button” so creativity isn’t trapped by rigidity.

Advice at the end is consistent: Roam has a low floor and high ceiling, so users should start by automating what they already do daily, learn the Smart Block anatomy (the required “42 smart block tag,” the workflow under it, and the double-semicolon trigger), and then layer complexity gradually. Because Smart Blocks are still in beta, the recommended mindset is experimentation, documentation, and sharing with the Roam42 community so others can build on working patterns and push the boundaries faster.
