== List of Commands ==
A complete list of commands and mandatory/optional parameters is shown at http://127.0.0.1:8111/ (when JOSM is running).

=== {{{load_and_zoom}}} ===#load_and_zoom
Instructs JOSM to download a bounding box from the API, zoom to the downloaded area and optionally select one or more objects.
{{{
GET /load_and_zoom?left=...&right=...&top=...&bottom=...&select=object[,object...]
}}}
where
||= **Parameter** =||= **Required/ \\ Optional** =||= **Meaning** =||
|| `bottom` ||  R  || Minimum latitude ||
|| `top` ||  R  || Maximum latitude ||
|| `left` ||  R  || Minimum longitude ||
|| `right` ||  R  || Maximum longitude ||
|| `new_layer` ||  O  || If '''true''', downloads to a new layer. (Overwrites user preference, see #19308) ||
|| `layer_name` ||  O  || Only valid when the data is loaded in a new layer; Gives JOSM a hint on how to name the layer ||
|| `layer_locked` ||  O  || Only valid when the data is loaded in a new layer; If '''true''', new layer is [wikitr:/Help/Action/LockedLayer locked] ||
|| `download_policy` ||  O  || Only valid when the data is loaded in a new layer; If '''never''' , download is [wikitr:/Help/Action/BlockDownload blocked] ||
|| `upload_policy` ||  O  || Only valid when the data is loaded in a new layer; If '''never''' or '''false''', upload is [wikitr:/Help/Action/EncourageDiscourageUpload blocked or discouraged] ||
|| `addtags` ||  O  || Optional parameter to add tags. The key and value is separated by "=" and multiple tags can be separated by a Pipe "|". See [#addtags details]. ||
|| `select` ||  O  || Comma-separated list of objects that should be selected. Object specifiers are combinations of the words "way", "node", or "relation", and the numerical object id. Example: {{{select=way38473,node12399,node54646}}}. Since r13212 the special value **currentselection** let JOSM keep its previous selection. ||
|| `zoom_mode` ||  O  || '''download''' | '''selection''', defaults to selection ||
|| `changeset_comment` ||  O  || Comment of the changeset ||
|| `changeset_source` ||  O  || Source of the changeset ||
|| `changeset_hashtags` ||  O  || Hashtags of the changeset ''(since r13109)'' ||
|| `changeset_tags` ||  O  || Optional parameter to add changeset tags. The key and value is separated by "=" and multiple tags can be separated by a Pipe "|". This command uses the same syntax as the [#addtags addtags] parameter. `changeset_comment` and `changeset_source` currently override the `comment` and `source` tags passed in this parameter, but this may change in the future. ''(since r15316)'' ||
|| `search` ||  O  || Search objects in the current data layer. See [wikitr:/Help/Action/Search Search] ||

==== Example ====
Start JOSM (don't forget to enable the !RemoteControl feature), then click on:

[http://127.0.0.1:8111/load_and_zoom?left=8.19&right=8.20&top=48.605&bottom=48.590&select=node413602999]

JOSM should now load an area in the German Schwarzwald and have the specified node selected. 


=== {{{zoom}}} ===
Instructs JOSM to zoom to the specified area and optionally select one or more objects.
{{{
GET /zoom?left=...&right=...&top=...&bottom=...&select=object[,object...]
}}}
Accepts the same parameters as the [#load_and_zoom load_and_zoom] command and uses the same code for zoom and selection. The only difference is that no data will be loaded from the API.

**Hint**: This command can also be used to select objects only. Just enter a small arbitrary area to the left..bottom entries and add the object list to the select= option.

=== {{{import}}} ===
Instructs JOSM to download the specified OSM file and add it to the current data set.
{{{
GET /import?url=...
}}}
where
||= **Parameter** =||= **Required/ \\ Optional** =||= **Meaning** =||
|| `url` ||  R  || The Request URL, including patterns. Must be the last parameter, everything after "&url=" is interpreted as URL, even if it contains "&" characters. ||
|| `new_layer` ||  O  || If '''true''', downloads to a new layer. (Overwrites user preference, see #19308) ||
|| `layer_name` ||  O  || Only valid when the data is loaded in a new layer; Gives JOSM a hint on how to name the layer ||
|| `layer_locked` ||  O  || Only valid when the data is loaded in a new layer; If '''true''', new layer is [wikitr:/Help/Action/LockedLayer locked] ||
|| `download_policy` ||  O  || Only valid when the data is loaded in a new layer; If '''never''' , download is [wikitr:/Help/Action/BlockDownload blocked] ||
|| `upload_policy` ||  O  || Only valid when the data is loaded in a new layer; If '''never''' or '''false''', upload is [wikitr:/Help/Action/EncourageDiscourageUpload blocked or discouraged] ||
|| `changeset_tags` ||  O  || Optional parameter to add changeset tags. The key and value is separated by "=" and multiple tags can be separated by a Pipe "|". This command uses the same syntax as the [#addtags addtags] parameter. First available in r16324. ||

=== {{{load_data}}} ===
''(since version 1.6)''

Instruct JOSM to load OSM data, directly encoded in the URL, instead of coming from an external file. This is only suited for smaller data (some browsers limit the maximum URL length), but it is faster (since no download is required), and in many cases where dynamically generated data is needed, it's easier to generate.

{{{
GET /load_data?new_layer=(true/false)&layer_name=...&mime_type=...&data=...
}}}
where
||= **Parameter** =||= **Required/ \\ Optional** =||= **Meaning** =||
|| `data` ||  R  || The XML data to load, this should be URL encoded in a way that also encodes the special characters &, = and ? to resp. %26, %3D and %3F. The JS [https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/encodeURIComponent encodeUriComponent()] method provides this functionality out of the box. ||
|| `new_layer` ||  O  || Choose to load the data in a new layer. (Overwrites user preference, see #19308) ||
|| `mime_type` ||  O  || Mime type of the data, by default this is "application/x-osm+xml", which is currently the only supported mime type, but in the future other mime types could be supported ||
|| `layer_name` ||  O  || Only valid when the data is loaded in a new layer; Gives JOSM a hint on how to name the layer ||
|| `layer_locked` ||  O  || Only valid when the data is loaded in a new layer; If '''true''', new layer is [wikitr:/Help/Action/LockedLayer locked] ||
|| `download_policy` ||  O  || Only valid when the data is loaded in a new layer; If '''never''' , download is [wikitr:/Help/Action/BlockDownload blocked] ||
|| `upload_policy` ||  O  || Only valid when the data is loaded in a new layer; If '''never''' or '''false''', upload is [wikitr:/Help/Action/EncourageDiscourageUpload blocked or discouraged] ||

=== {{{open_file }}} ===

{{{
GET /open_file?filename=...
}}}
where
||= **Parameter** =||= **Required/ \\ Optional** =||= **Meaning** =||
|| `filename` ||  R  || The local file to open in JOSM (Ie: /tmp/test.osm) ||


=== {{{imagery}}} ===#imagery

==== Example ====
[http://localhost:8111/load_object?new_layer=true&objects=w106159509]


=== {{{add_node}}} ===
Instructs JOSM to create a new node at the given coordinates.

**Note**: This action requires the permission ''Create new objects'' which is disabled by default.

{{{
GET /add_node?lon=...&lat=...
}}}
where
||= **Parameter** =||= **Required/ \\ Optional** =||= **Meaning** =||
|| `lon` ||  R  || The longitude of the node ||
|| `lat` ||  R  || The latitude of the node ||
|| `addtags` ||  O  || Optional parameter to add tags. The key and value is separated by "=" and multiple tags can be separated by a Pipe "|". See [#addtags details]. ''(since v1.5)'' ||

==== Example ====
http://localhost:8111/add_node?lon=13.3&lat=53.2


=== {{{add_way}}} ===
Instructs JOSM to create a new way with new way nodes at given coordinates.

**Note**: This action requires the permission ''Create new objects'' which is disabled by default.

{{{
GET /add_way?way=lat1,lon1;lat2,lon2;...
}}}
where
||= **Parameter** =||= **Required/ \\ Optional** =||= **Meaning** =||
|| `way` ||  R  || Pairs of latitude, longitude coordinates separated by semicolon. ||
|| `addtags` ||  O  || Optional parameter to add tags. The key and value is separated by "=" and multiple tags can be separated by a Pipe "|". See [#addtags details]. ''(since v1.5)'' ||

==== Example ====

=== {{{version}}} ===
This command returns the current protocol version of the installed !RemoteControl interface. Developers can use it to query for a running instance of JOSM and also determine whether the requested functionality is available in the client.

{{{
GET /version[?jsonp=callback]
}}}
where
||= **Parameter** =||= **Required/ \\ Optional** =||= **Meaning** =||
|| `jsonp` ||  O  || Jsonp callback for older browsers not implementing ​Cross-Origin Resource Sharing (CORS) ||

The command returns a json object containing an application identifier that is always "JOSM !RemoteControl", a major number and a minor number. Compatible protocol changes result in an increase of the minor number. Incompatible changes increase the major number. So a client application knowing of protocol version 1.0 can still talk to JOSM having 1.1. But it's not guaranteed to be working with 2.0. So the client should verify the major number.

A typical output looks like this:
{{{
#!js
{
   "protocolversion": {
      "major": 1, 
      "minor": 0
   }, 
   "application": "JOSM RemoteControl",
   "version": 16587 // JOSM version (since r16587)
}
}}}
For older browsers not implementing [http://en.wikipedia.org/wiki/Cross-Origin_Resource_Sharing Cross-Origin Resource Sharing (CORS)] the command provides the possibility for jsonp callback. Load the URL in a script tag and supply the name of a callback that will receive the JSON data.

Following is some sample code that checks for CORS capabilities and uses [http://en.wikipedia.org/wiki/JSONP JSONP] as a fallback solution.

=== {{{openapi.json}}} ===
JOSM RemoteControl as [https://swagger.io/specification/ OpenAPI Specification]

* http://localhost:8111/openapi.json
* https://petstore.swagger.io/?url=http://localhost:8111/openapi.json


=== Adding, changing or deleting tags === #addtags
Try this example:  
[http://localhost:8111/load_and_zoom?addtags=wikipedia%3Ade=Weiße_Gasse%7Cmaxspeed=5&select=way23071688,way23076176,way23076177,&left=13.739727546842&right=13.740890970188&top=51.049987191025&bottom=51.048466954325]. 
(Works also with the zoom-command)

The user must review the tags and the selection before the tags are applied to the selected objects.
If the tag exists on some objects, it will be replaced.

Since protocol version 1.5 
- `add_node` and `add_way` commands support `addtags` parameter
- It is possible to use `=` character in value and all leading/trailing spaces are trimmed.
[http://localhost:8111/add_node?lon=13.3&lat=53.2&addtags=natural=tree%7Cname=%20%20%20==Great%20Oak==] (creates node with natural=tree an name="==Great Oak==")
- If empty value is found, tag is to be deleted from objects (checkbox-confirmation is needed)
[http://localhost:8111/load_and_zoom?addtags=wikipedia%3Ade=%7Cmaxspeed=&select=way23071688,way23076176,way23076177,&left=13.739727546842&right=13.740890970188&top=51.049987191025&bottom=51.048466954325]. 

=== Other commands ===
Remotecontrol allows other plugins to add additional commands. The other registers a RequestHandler class and specifies a command to be handled by this class. The command syntax has to be defined by the other plugin.

==== Reverter ====
Reverter plugin since version 27091 makes use of this feature. See [source:osm/applications/editors/josm/plugins/reverter/src/reverter/RevertChangesetHandler.java RevertChangesetHandler.java].

==== Mapillary ====
See [https://github.com/JOSM/Mapillary/blob/master/src/main/java/org/openstreetmap/josm/plugins/mapillary/io/remotecontrol/MapillaryRemoteControl.java MapillaryRemoteControl.java].
Either `sequence` or `photo` must be specified, but not both. Since the remote control class was written for multiple imagery sources, the id for either `sequence` or `photo` ''must'' be prefixed with `Mapillary/`.
