That can be combined with other attributes, such as type:way highway=primary. Marko ___ josm-dev mailing list josm-dev@openstreetmap.org http://lists.openstreetmap.org/listinfo/josm-dev
Re: [josm-dev] Function to select or download a sequence of ways?
Hi Karl, To the best of my knowlege there is no such function yet ... Now there is: http://wiki.openstreetmap.org/wiki/JOSM/Plugins/WaySelectorPlugin Thanks to your reply and the availability of WayDownloaderPlugin source code, I got an easy start. I posted some ideas for further development to the above wiki page, but the plugin already scratches my itch (selecting the mainland coastline in a large natural=coastline map extract). (3) you can listen to the current selection. See org.openstreetmap.josm.data.osm.event.SelectionEventManager I might look at this later, to update the enabled/disabled state of the plugin based on the current selection.

2010/3/9 Marko Mäkelä marko.mak...@iki.fi: Before I start reinventing the wheel in JOSM, I would like to know if there is a function or plugin that allows to select a non-branching sequence of ways. It would be nice if the selection function could optionally be restricted to the current selection, just like the search dialog, and if some predicates could be assigned to the ways, say, highway=tertiary or natural=coastline, so that any branches where the predicate does not hold would be ignored. another selection-feature I'm missing quite often (maybe it is already there and I don't know how to use it) is the use of the selection-rectangle to select ways but not nodes.

Re: [josm-dev] Function to select or download a sequence of ways?
Hi Marko To the best of my knowlege there is no such function yet ... As a further development, it could be useful to create a selective download function (follow this way until reaching a branch or a given bounding box). ... except for this function which sounds like what the waydownloader plugin provides. Selection is a core thing. You can use it from plugins in three ways. (1) you can influence the current selection. See setSelected() on DataSet. Invoke it on the current data layer (Main.main.getEditLayer()) (2) you can get the current selection. See getSelected() on DataSet. Invoke it on the current data layer (Main.main.getEditLayer()) (3) you can listen to the current selection.

With such a selection function, it would be easy to select the coastline of an area within a natural=coastline extract of the planet extract, or to select a section of highway or railway for defining a route relation, for instance. Last, some questions to help getting me started, in case this does not exist yet. Is the selection a core thing, or can this be done in a plugin? Where should I start looking first?
