From 1fe1d13c600b7dfe421b3b99b833b7d5d1232724 Mon Sep 17 00:00:00 2001 From: Dennis Fink Date: Thu, 23 Jul 2026 00:18:21 +0200 Subject: Add GPX trail maps to blog posts This adds a trail flow block so posts can include attached GPX files as interactive maps with route display, elevation charts, activity summaries, and start/finish markers. The trail assets are loaded only when needed, keeping the shared templates clean while vendoring the Leaflet dependencies required for offline, self-hosted map rendering. --- assets/static/vendor/leaflet-elevation/libs/leaflet-ruler.min.js | 1 + 1 file changed, 1 insertion(+) create mode 100644 assets/static/vendor/leaflet-elevation/libs/leaflet-ruler.min.js (limited to 'assets/static/vendor/leaflet-elevation/libs/leaflet-ruler.min.js') diff --git a/assets/static/vendor/leaflet-elevation/libs/leaflet-ruler.min.js b/assets/static/vendor/leaflet-elevation/libs/leaflet-ruler.min.js new file mode 100644 index 0000000..e732020 --- /dev/null +++ b/assets/static/vendor/leaflet-elevation/libs/leaflet-ruler.min.js @@ -0,0 +1 @@ +L.Control.Ruler=L.Control.extend({options:{position:"topright",circleMarker:{color:"red",radius:2},lineStyle:{color:"red",dashArray:"1,6"},lengthUnit:{display:"km",decimal:2,factor:.001,label:"Distance:"},angleUnit:{display:"°",decimal:2,factor:360,label:"Bearing:"}},initialize:function(options){L.setOptions(this,options),this._layers=L.layerGroup(),this._enabled=!1},onAdd:function(map){this._defaultCursor=map._container.style.cursor,this._map=map;let container=L.DomUtil.create("div","leaflet-bar");return container.classList.add("leaflet-ruler"),L.DomEvent.disableClickPropagation(container),L.DomEvent.on(container,"click",this._toggleMeasure,this),this._container=container},onRemove:function(){L.DomEvent.off(this._container,"click",this._toggleMeasure,this)},_attachMouseEvents:function(){let map=this._map;map.doubleClickZoom.disable(),L.DomEvent.on(map._container,"keydown",this._escape,this),L.DomEvent.on(map._container,"dblclick",this._closePath,this),map._container.style.cursor="crosshair",map.on("click",this._addPoint,this),map.on("mousemove",this._moving,this)},_removeMouseEvents:function(){let map=this._map;map.doubleClickZoom.enable(),L.DomEvent.off(map._container,"keydown",this._escape,this),L.DomEvent.off(map._container,"dblclick",this._closePath,this),map._container.style.cursor=this._defaultCursor,map.off("click",this._addPoint,this),map.off("mousemove",this._moving,this)},_disable:function(){this._enabled=!1,this._container.classList.remove("leaflet-ruler-clicked"),this._map.removeLayer(this._layers),this._layers=L.layerGroup(),this._latlngs=[],this._totalLength=0,this._removeMouseEvents()},_enable:function(){this._enabled=!0,this._container.classList.add("leaflet-ruler-clicked"),this._circles=L.featureGroup().addTo(this._layers),this._polyline=L.polyline([],this.options.lineStyle).addTo(this._layers),this._layers.addTo(this._map),this._latlngs=[],this._totalLength=0,this._attachMouseEvents()},_toggleMeasure:function(){this._enabled?this._disable():this._enable()},_drawTooltip:function(latlng,layer,incremental){let clickCount=this._latlngs.length,lastClick=clickCount?this._latlngs[clickCount-1]:latlng,bearing=this._calculateBearing(lastClick,latlng),distance=lastClick.distanceTo(latlng)*this.options.lengthUnit.factor,totalLength,plusLength;incremental?(totalLength=(clickCount?distance+this._totalLength||0:distance).toFixed(this.options.lengthUnit.decimal),plusLength=clickCount?'
