[[TranslatedPages]] = Preferences > Plugins = Plugins extend the core functionality of JOSM. The [wiki:Plugins list of JOSM plugins] explains which plugins are available and with what kind of functionality they extend JOSM. Most JOSM users don't work with the bare JOSM core only. They usually install at a set of at least 3-5 plugins, including the the important wmsplugin and validator-plugin (integrated to core for now). == Installing plugins == 1. Launch the '''Preferences''' dialog 2. Select the tab '''Plugins''' 3. Click on '''Download list''' do download the list of available plugins 4. Tick the checkbox for every plugin you want to install 5. Click on '''Update plugins''' JOSM will download and install the plugins. You have to restart JOSM to '''load and activate''' the newly downloaded plugins. == Manually updating plugins == 1. Launch the '''Preferences''' dialog 2. Select the tab '''Plugins''' 3. Click on '''Download list''' do download the list of available plugins 4. Tick the checkbox for every plugin you want to update 5. Click on '''Update plugins''' JOSM will download and install the most recent version of the selected plugins. You have to restart JOSM to '''load and activate''' the newly downloaded plugins. == Automatically updating plugins == #AutomaticUpdate JOSM checks at startup whether the currently active plugins should be updated. JOSM attempts to update the plugins * if JOSM itself has been updated since the last plugin update. This is called the '''version based update mode'''. * if a certain periode of time has elapsed since the last plugin update. This is called the '''time based updated mode'''. In the preferences you can define the policy for updating plugins in version or time based mode. 1. Launch the '''Preferences''' dialog 2. Select the tab '''Plugins''' 3. Click the tab '''Plugin update policy''' Select the radio button '''Ask before updating''' if JOSM shall ask before updating plugins in version and/or time based update mode. Select the radio button '''Always update without asking''' if JOSM shall automatically update plugins without asking. Select the radio button '''Never update''' to disable version or time based automatic update. JOSM will skip automatic update at startup if this policy is selected. ---- Back to [wiki:/Help/Action/Preferences Preferences][[Br]] Back to [wiki:Help Main Help]
