Revision history for HTML-OSM

0.12	Fri Oct 23 09:19:01 PM EDT 2026
	[ Enhancements ]
	- new(search => 0) leaves out the Nominatim search box, the "Clear search
	  markers" button and their script, so nothing typed on the page leaves
	  the reader's machine.  The "Reset Map" button stays.  The default is
	  still to include the search box
	- new(max_zoom => N) sets maxZoom (0-28) on the tile layer, for tile
	  servers that have no tiles beyond a given zoom level
	- New add_circle_marker() draws a filled circle with a radius in pixels
	  and a hex colour, for bubble maps.  It takes the same points as
	  add_marker(), joins the cluster group when cluster => 1 is set, and
	  counts towards the map's bounds, so a map of circles alone needs no
	  center() call
	- onload_render() checks max_zoom and the circle markers again, as it does
	  zoom, width and height

	[ Tests ]
	- Add t/options.t (search, max_zoom) and t/circle_marker.t

0.11	Mon Oct 19 09:48:31 PM EDT 2026
	[ Bug Fixes ]
	- Heatmap radius and blur are now forced to positive numbers, so they can
	  no longer inject JavaScript
	- onload_render() checks zoom, width and height again (values from a
	  config file or a clone skip new()'s checks) and falls back to the
	  defaults with a warning
	- CDN URLs are HTML-escaped in the <head> fragment
	- A lone carriage return in a label no longer breaks the JavaScript
	- add_marker('') and center('') return 0 instead of croaking from a
	  private helper; a coordinate with no lat/lon and no address is skipped
	- A user agent passed in by the caller is no longer reconfigured
	- Some perls (seen with 5.38.0 on macOS) print and read numbers with the
	  locale's decimal point, so under de_DE 51.5074 printed as "51,5074" and
	  "51.5074" was read as 51.  Coordinates were rejected, and the computed
	  map centre lost its fractions.  Coordinates are now always written with
	  a '.', converted to numbers without the locale, and range-checked
	  correctly ("90.5" was read as 90 and accepted).  JSON layers are
	  encoded under the C numeric locale, and heatmap radius/blur accept
	  decimals such as "12.5"
	  Fixes https://matrix.perl-magpie.org/results/97965e64-9dc9-11f1-963c-fccfcb508d96

	[ Enhancements ]
	- new(tile_url => ...) replaces the OpenStreetMap tile layer, so maps can
	  use an internal tile server or run on an air-gapped network
	- new(tile_attribution => ...) replaces the map credit; the default now
	  links to the OpenStreetMap copyright page
	- new(email => ...) adds a contact address to Nominatim requests, as the
	  Nominatim usage policy asks

	[ Documentation ]
	- Add a DESCRIPTION section
	- MESSAGES tables now match the exact croak text and list the warnings
	- Document that only one map can be rendered per page

	[ Build ]
	- Declare IPC::System::Simple as a runtime prerequisite: autodie qw(:all)
	  needs it when the module loads
	- Set MIN_PERL_VERSION to 5.010
	- Remove ExtUtils::MakeMaker from PREREQ_PM (it stays in CONFIGURE_REQUIRES)
	- Declare HTTP::Response for tests; drop unused Test::JSON,
	  Test::HTML::Lint and Test::Warnings

	[ Tests ]
	- Cover the default tile URL, a configured tile URL and JS-string escaping
	- Cover tile_attribution, email, the render-time checks and the new
	  escaping helpers
	- Simulate comma-decimal number printing so the locale fix is tested on
	  every platform, and check the rendered output under real locales

0.10	Sun Jul 12 21:23:33 EDT 2026
	[ Bug Fixes ]
	- Don't try to call a method on an uninitialized variable
	- Use consistent default sizes
	- Bump minimum versions
	- Set maximum zoom to 19
	- Fix function-style HTML::OSM::new() with arguments blessing into wrong package

	[ Enhancements ]
	- Re-enable search box and reset button in rendered map
	- Add "Clear search markers" button to remove dynamically-added markers
	- add_geojson(): render GeoJSON layers via Leaflet-native L.geoJSON()
	- add_heatmap(): render heatmap layers via Leaflet.heat plugin
	- add_gpx(): render GPX tracks from a URL via leaflet-gpx plugin
	- add_choropleth(): data-driven colour-fill layers; colours pre-computed in Perl
	- new(cluster=>1): group markers with Leaflet.markercluster plugin
	- onload_render() no longer requires point markers when GeoJSON/heatmap/GPX/choropleth data is present
	- Use Params::Validate::Strict on new()
	- Added the test dashboard at https://nigelhorne.github.io/HTML-OSM/coverage/

	[ Tests ]
	- Started fuzz testing
	- Extend new() fuzz schema with zoom, height, width and min_interval inputs
