Obsidian - Meta Bind - Input Fields and Calculators

Meta Bind turns Obsidian notes into interactive RPG calculators by combining saved input fields with live-updating “views” that can run math and pull data from other notes. The payoff is practical: dropdowns and selectors keep their chosen values instead of resetting when a note is reopened, and calculations refresh in near real time—fixing the lag and manual refresh problem many users associate with earlier DataView-style approaches.

The plugin’s core workflow is built around two components. “Import fields” create user inputs—text boxes, dropdowns, sliders, date/time pickers, image selectors, and more—and store the selected results into note properties. “Views” then display those stored properties and can also perform formulas, including referencing properties from other notes. That combination is what powers everything from simple pickers to full travel and jump calculators.

A standout example is a travel calculator refreshed by dropdown-driven party settings. Changing an animal type (e.g., donkey walking vs. griffin flying) updates base speed, which then cascades into travel time estimates between towns. The same calculator also reacts to party configuration inputs like travel duration per day, exhaustion level, travel mode, route safety, familiarity, party size, wealth level, and whether meals are included—driving outputs such as days to travel and travel costs (gold and copper) based on coaching, messenger, and ship-per-day assumptions. The results are stored in properties, so other notes can reuse the same configuration data.

Beyond calculators, Meta Bind addresses a long-standing annoyance: dropdowns that don’t persist. Earlier workarounds using HTML in Obsidian let users select options visually, but the chosen value wouldn’t reliably save, so it reverted on reopening. Meta Bind’s saved-value dropdowns keep the underlying property consistent, enabling stable templates and repeatable character- or campaign-driven calculations.

There’s also a known edge case with inline select controls: if multiple options share the same underlying value, reopening the note may default to the first matching option (the transcript’s example shows an animal changing back to “donkey” when another option shares the same speed value). The creator’s workaround adds tiny fractional offsets (e.g., 0.01, 0.02, 0.03) to force unique stored values, then rounds during calculations so the displayed results remain clean.

Implementation details matter because Meta Bind is “advanced” and actively changing. The transcript emphasizes reading the plugin documentation and GitHub example vault, which includes ready-to-copy snippets. It also distinguishes inline vs block input field styles (with some features available only in block mode) and shows how views can be written inline using property references and math operators.

Finally, the transcript positions Meta Bind as a stepping stone toward richer RPG tooling in Obsidian—currency converters, D&D 5e travel calculators, and even a Pathfinder 2e jump calculator—while encouraging users to copy examples, modify them, and share improvements in the community Discord.
