Solve

Solve 2.0 is here. The engine has been rewritten from scratch. The old Ohm.js grammar is gone, replaced by a lexer, a parser and a bytecode virtual machine, published separately as solve-engine. Results are faster and more consistent, and there is now a proper syntax reference in place of the old wiki. See the release notes for the full list of changes.

Going forward, new syntax and engine features ship through solve-engine. This repository consumes it as a dependency and updates automatically when a new version is released. Engine feature requests and syntax questions belong there. This repository is for the Obsidian integration itself: settings, rendering and editor behaviour.

Solve embeds solve-engine, a standalone natural language expression engine, in Obsidian's editor. Every line is evaluated as you type, and the result appears next to it without leaving the note.

10 + 20 / 200 * 4              // = 10.40
days since 01/01/2023          // = 233 days
01/01/2023 + 20 days           // = Sat Jan 21 2023
15% of 2400                    // = 360
100cm + 2m                     // = 300.00 cm
$100 + $250                    // = $350.00

The syntax reference is the full list of what the engine understands: arithmetic, dates, percentages, units, currency, dice, conditionals and more. Everything on that page works the same way inside a note.

Install

From Obsidian

Open Settings, go to Community plugins, then Browse. Search for "Solve" and click Install, then Enable.

Manually

Copy main.js, styles.css and manifest.json into VaultFolder/.obsidian/plugins/solve/. Reload Obsidian and enable the plugin from Community plugins.

How it works

Each line is evaluated independently as you type. A result that resolves immediately, such as arithmetic, dates or units, renders inline right away. A result that depends on an async source, such as currency conversion or live weather, shows a pending state until it resolves. Click a result to commit it into the line as text.

Evaluation, caching and formatting all come from solve-engine. This repository wires that engine into Obsidian's editor (CodeMirror 6) and exposes the parts of it that make sense as user-facing settings: safety limits, result formatting and inline solve commit behaviour. See solve-engine for the engine itself, including its architecture and design notes.
