GunsNPrices

Spec tables for gun and ammo listings, an ammo purchase log that totals rounds and cost per round, and a command that cleans up caliber names. Write product titles the way stores write them; the plugin reads brand, model, caliber, magazine capacity, barrel length and rounds per box.

It runs the gunsnprices title parser, the one behind the price comparison site GunsNPrices, entirely inside Obsidian. No account, no API key, and it works offline.

Spec tables: gunspecs

One product title per line. Add a price with a currency symbol ($18.99) or after a |, and ammo gets a cost per round.

```gunspecs
Federal 9mm 115gr 50rd $18.99
Glock 19 Gen 5 MOS 9mm 4.02" 15rd Pistol
```

renders a table for each title:

Add layout: compare to put every product in one table, which is handy for comparing offers:

```gunspecs
layout: compare
Federal 9mm 115gr FMJ 50rd $18.99
Winchester 9mm 115gr FMJ 1000 Round Case $289.99
```

Lines starting with # or // are ignored.

Ammo log: ammo-log

One purchase per line: an optional date, what you bought, and the price.

```ammo-log
2026-10-20 | Federal 9mm 115gr FMJ 50rd x4 | $18.99
2026-10-25 | CCI Blazer Brass .45 ACP 230gr FMJ 50rd | $27.49
2026-11-01 | Winchester 9mm 115gr FMJ 1000 Round Case | $289.99 total
```

With more than one caliber, a second table shows each caliber's rounds, money and average cost per round (here 9×19mm Parabellum: 1,200 rounds, $365.95, $0.30 per round).

How lines are read:

• Boxes: x4, × 4, 4x, 4 boxes or qty 4. The x 19 in 9 x 19 is not taken as a box count.
• Price: the price of one box. Write total after it ($75.96 total) when it is the price of all boxes.
• Rounds: read from the title (50rd, 20 rounds, box of 25, 1000 Round Case, 50/box). Lines without a round count still count toward money spent, but are left out of the average, and the block says so.
• The | separators are optional: 2026-10-20 Federal 9mm 50rd $18.99 works too. Prices use a dot for decimals.

Command: normalize caliber in selection

Select caliber names and run Normalize caliber in selection from the command palette. Each line, table cell or comma-separated item that is only a caliber is rewritten to one standard name out of 293 calibers:

Text that holds more than a caliber, such as 9mm 115gr FMJ or 9mm +P, is left alone, so the command never drops words. The command has no default hotkey; you can assign one in Settings → Hotkeys.

Settings

• Link calibers to price pages (off by default): caliber names in rendered blocks become links to that caliber's price comparison page on gunsnprices.com.
• Currency symbol (default $): shown before prices and cost per round. Prices in notes are read with this symbol or with $.

Network use and privacy

• The plugin makes no network requests. All parsing happens on your device with data bundled in main.js.
• No telemetry, no analytics, no ads, no account.
• The only link to an outside site is the optional caliber link described above. It is off by default, and nothing is loaded until you click a link.
• It reads only the code blocks and the selection you run it on, and changes text only when you run the command.

Install

From Obsidian: Settings → Community plugins → Browse, search for "GunsNPrices", install and enable.

Manually: copy main.js, manifest.json and styles.css from the latest release into <your vault>/.obsidian/plugins/gunsnprices/, then enable the plugin in Settings → Community plugins.

Works on desktop and mobile. On iOS it needs iOS 16.4 or later, because the parser uses regular expression features that older iOS versions lack.

Size

main.js is about 450 KB (about 80 KB gzipped). Most of it is data: 293 calibers with their store spellings and the model dictionaries for 50 firearm brands. The data is loaded once when the plugin starts.

Development

npm install
npm run dev     # watch build into main.js
npm run build   # type check + production build
npm run lint    # eslint with eslint-plugin-obsidianmd
npm test        # type check tests + vitest
