naiveGPXlogger for SignalK 
v. 0.0
A simple plugin that just records a stream of coordinates to a .gpx file in the user-defined directory.
Features
- record points at a specified time interval or as coordinates arrive
- recording points at a specified distance
- creating a new segment when the position is lost during the specified time
- one log for the whole trip or a separate log every day
- server reboot resistance
Usage
By end user
Check and uncheck checkbox "Write log" on plugin configuration page in "Plugin Config" menu of SignalK web admin.
The GaladrielMap can show a recordable file and has a switch in the interface to control the log recording.
By programmer
The naiveGPXlogger creates a navigation.trip.logging path in the SignalK data model. The value by this path is:
{
"status": boolean,
"logFile": "full/log/file/name"
}
where "status" is the state of the record: is on or off; and "logFile" - full name of log file in server file system.
In order to enable logging, the client application must send a delta message for this path with "status": true
If at the same time the "logFile" will contain a directory path (with trailing slash) - the log will be recorded in this directory.
The log recording is stopped by sending a delta message with "status": false
The basic example is in the sample.html
