Each tree entry now shows a small waypoint/track icon based on a
cheap substring check for <wpt>/<trk> (Maptool::Gpx.kinds) rather than
a full REXML parse, since re-parsing a several-thousand-waypoint file
on every tree fetch would make the panel noticeably slower to open.
Also fix a real drop-target bug: .gpx-tree had no flex:1, so a
short/empty tree left blank panel space below it that wasn't part of
the drag & drop target — dropping a file there silently did nothing.
Restructure the map controls from MapLibre corner buttons into a left
sidebar of icons with flyouts/panels (radar, GPX, GNSS), matching
OsmAnd's layout more closely:
- Base map and GPX selection are now full-height side panels docked
next to the sidebar (not small dropdown flyouts or a right-docked
panel), opening/closing exclusively via a small shared event bus
(panels.js) so only one is ever open at a time.
- The GPX panel's upload/new-folder controls are now icon buttons in
the header instead of an always-visible dropzone and form; dragging
a GPX file onto the tree, a specific folder, or straight onto the
map itself all upload it.
- New: Maptool::GpsdClient (lib/maptool/gpsd_client.rb) streams live
GNSS fixes from a local gpsd daemon over Server-Sent Events
(/api/gnss/stream) to a marker on the map (public/js/gnss.js) — one
background gpsd connection shared by every browser tab.
- The online map style (public/js/osmand-style.js) is now styled to
resemble OsmAnd's own rendering, applied to both the online and
offline (PMTiles) styles.
Also adds a GeolocateControl (browser geolocation) next to the zoom
controls.
Uploading is now drag & drop (or click to browse) instead of a form;
folders can be created any time, not just during upload; files can be
dragged onto a folder to move them, or dropped elsewhere in the tree
to move back to the top level; files and folders can be deleted. Both
drag sources (an OS file drag and dragging an existing tree entry)
land on the same drop targets, told apart by a custom drag payload
type versus the browser's own "Files" type.
Also sort folders before files in the tree (previously interleaved
alphabetically).
Upload GPX files into a folder hierarchy (traversal-safe path
resolution against the store root), browse them in a tree panel, and
toggle each one's waypoints/tracks on the map. Waypoints render as
clickable points showing name, description and time; bare URLs in the
description are turned into safe links. GPX layers survive switching
between the Online/Offline base map, same as the radar overlay.
Adds rexml as an explicit dependency — it moved to a bundled gem in
this Ruby version and isn't picked up by Bundler otherwise.
