fix(docs): write Map View lat,lng location without MetaEdit in geocoding example

[chhoumann]

Summary

The "Add location long-lat from address" example (docs page, docs/public/scripts/getLongLatFromAddress.js) now writes the location property with app.fileManager.processFrontMatter, in the lat,lng format that Map View recommends and writes itself. MetaEdit is no longer needed. The fix also covers an address-encoding bug that put some places in the wrong country.

What was wrong

1. Format. With MetaEdit 1.10.3 the script wrote location: "[48.8582599, 2.2945006]", a quoted string rather than the [lat, long] list the page described. Map View 6.1.4 still places it: getFrontMatterLocation in src/fileMarker.ts runs its unanchored COORDINATES regex over string values. But that string shape isn't one of Map View's documented location formats. Map View recommends location: lat,lng and writes that format itself (verifyOrAddFrontMatter / processFrontMatter in its src/utils.ts and src/main.ts).
2. Encoding. The address went into the URL unencoded. For AT&T Stadium, Arlington, Texas, Nominatim received q=AT and the note got "[47.5939700, 14.1245600]" (Austria). Properly encoded, Nominatim returns 32.7478503, -97.0928337.
3. Docs. The page required MetaEdit, and its "All Multi" note was out of date. MetaEdit 1.10.3 writes through processFrontMatter, so in All Multi mode it just wraps the value in a one-item list.

Changes

• Script: checks for an active file before prompting, builds the query with URLSearchParams (limit=1), fetches with Obsidian's requestUrl, and sets frontmatter.location = \${lat},${lon}`. An existing location` is replaced. When there are no results, it shows a notice and leaves the note unchanged.
• Docs page: MetaEdit prerequisite removed, Nominatim explained (free, no key), exact output shown, replacement behaviour documented. The All Multi note is replaced with a migration note: old values keep working in Map View, and the property name can be changed if Map View's key was customised. slug is unchanged.
• The stale 21 MB longLatDemo.gif (old UI, old format, no longer referenced) is replaced with a 210 KB screenshot of the result in Map View.
• Regression spec tests/examples/getLongLatFromAddress.test.ts covers the lat,lng value, keeping other properties, replacing an existing location, &/# reaching Nominatim intact, no results, no active file, and a cancelled prompt. All 6 tests fail against the old script and pass against the new one.

Proof (real Obsidian 1.13.7, throwaway vault with made-up notes)

Setup: the isolated e2e runner vault, QuickAdd built from this branch, Map View 6.1.4 and MetaEdit 1.10.3 from their GitHub releases, and a macro choice Mapper running the user script. Each run opened the note, started the choice, typed the address into QuickAdd's input prompt, and pressed Enter. Afterwards I read the file, metadataCache and Map View's layerCache.

Before (master script, MetaEdit enabled):

# "Eiffel Tower, Paris"
location: "[48.8582599, 2.2945006]"          # string; Map View marker 48.8582599, 2.2945006
# "AT&T Stadium, Arlington, Texas"
location: "[47.5939700, 14.1245600]"         # wrong: Austria

After (this branch):

# Places/Eiffel Tower.md — "Eiffel Tower, Paris" (existing tags kept)
tags:
  - travel
location: 48.8582599,2.2945006
# Places/Stadium.md — "AT&T Stadium, Arlington, Texas" (replaced the wrong value)
location: 32.7478503,-97.0928337
# Places/Colosseum.md — "Colosseum, Rome", with MetaEdit DISABLED
location: 41.8909421,12.4919030

Map View layerCache after the runs: FileMarker for Places/Eiffel Tower.md at 48.8582599, 2.2945006, Places/Stadium.md at 32.7478503, -97.0928337, and Places/Colosseum.md. An unknown address showed No results found for "…" and left the note unchanged. dev:errors: no errors captured.

(Map View's tile source was switched to OpenStreetMap in the test vault, because its default CartoDB tiles need an API key.)

Checks

• pnpm run test: 447 files / 5806 tests passed.
• pnpm run build-with-lint: passed; main.js, manifest.json and versions.json are unchanged.
• docs/: pnpm run build passed, and I checked the rendered page in a browser.

Release / migration impact

Docs only; no plugin code changes. Users who re-download the script no longer need MetaEdit. Values written by the old script keep working in Map View, and re-running the macro on a note replaces its location.

Note

Rewrite geocoding example to write Map View lat,lng without MetaEdit

• The QuickAdd script in getLongLatFromAddress.js now prompts for an address, looks it up via Nominatim with a URL-encoded query limited to one result, and writes the first match to frontmatter location as a comma-separated lat,lng string using Obsidian's file manager API instead of MetaEdit.
• The script stops with a notice when there is no active file, the prompt is cancelled, the lookup fails, or no results are returned; existing frontmatter properties are preserved and an existing location value is replaced.
• Updates Macro_AddLocationLongLatFromAddress.md for the new setup (Nominatim, no MetaEdit), swaps the old GIF for a Map View screenshot, and notes that MetaEdit-written locations keep working.
• Adds tests in getLongLatFromAddress.test.ts that load and run the checked-in script against mocked Obsidian APIs, covering success, replacement, URL encoding of & and #, failures, and cancellations.
• Behavioral Change: locations are now written as lat,lng instead of bracketed coordinates, and the MetaEdit dependency is removed from the example.

Summary by CodeRabbit

• Features
  • Address-to-coordinate lookup saves the first matching result as a comma-separated value in the active note’s location property.
  • The lookup reports missing addresses, no matching locations, and request failures. It skips the lookup if there is no active note or the prompt is cancelled.
• Documentation
  • Updated the example guide with usage and compatibility details, including the internet connection requirement and how to change the property name.

📝 Walkthrough

Walkthrough

The address macro checks for an active note, requests one geocoding result through Obsidian’s request API, and writes the first result’s coordinates to the note’s location frontmatter property. Tests and documentation cover the updated behavior.

Changes

Address-to-location macro

Layer / File(s)	Summary
Geocoding, frontmatter updates, and validation docs/public/scripts/getLongLatFromAddress.js, tests/examples/getLongLatFromAddress.test.ts, docs/src/content/docs/docs/Examples/Macro_AddLocationLongLatFromAddress.md	The script encodes the address in a Nominatim request and writes the first result as a comma-separated coordinate value. It handles missing results and request errors. Tests cover success, replacement, URL parameters, and skipped cases. The documentation describes the coordinate format, requirements, and usage.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~12 minutes

Change: Bug fix

Merge Risk: ⚪ Minimal · up to 84a11

The macro writes the documented coordinate format and reports the examined failure paths. No identified issue prevents merging after normal checks.

Security Architecture Review

Security architecture risk: 🔵 Low · up to d3c36

The user-run example now captures the selected note before requesting an address, encodes the address for geocoding, and writes the resulting location through Obsidian’s frontmatter API. No newly exposed entrypoint or demonstrated security regression was found. Behavior during overlapping runs or host-API failures remains unverified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The evidenced exposure is an address supplied to the user-run example, a request to Nominatim, and a location write to the captured note. The flagged test-harness entrypoint does not establish a remotely reachable or cross-note entrypoint.

Trust Boundaries and Controls

• observed — The external geocoding response supplies the coordinates written to frontmatter. The handler checks for an active file and a nonempty result, but does not itself validate the returned coordinate values.

Resilience and Maintainability Implications

• inferred — Each successful invocation assigns location after its own request completes, so the source provides no freshness ordering between overlapping invocations. The prior flow also lacked an evidenced concurrency guard; a PR-introduced security regression is not established.

_{A rabbit checks the note before the prompt,
Then sends an address on its way.
One result brings two numbers back,
Comma-joined where frontmatter stays.
If none arrive, a notice says so,
And rabbit hops through tests today.}
