It is written mainly in C with some C++ and uses the GTK+ 3 toolkit\&. It is available for Linux, other POSIX operating systems and Windows\&. .PP Homepage: \m[blue]\fBhttp://viking\&.sf\&.net\fR\m[] .PP Viking is licensed under the GNU GPL\&. .SH "OPTIONS" .PP \fBfile\fR .RS 4 Specify file(s) to load at start\&. .sp If a filename is in the \*(Aqgeo\*(Aq URI sheme (\m[blue]\fBRFC5870\fR\m[]\&\s-2\u[1]\d\s+2) then the positional information will be used (and it will not attempt to load it as a file) .RE .PP \fB\-\fR .RS 4 Read input from standard in\&. .RE .PP \fB\-d\fR, \fB\-\-debug\fR .RS 4 Enable debug output\&. .RE .PP \fB\-V\fR, \fB\-\-verbose\fR .RS 4 Enable verbose output\&. .RE .PP \fB\-?\fR, \fB\-\-help\fR .RS 4 Show help options\&. .RE .PP \fB\-v\fR, \fB\-\-version\fR .RS 4 Show version\&. .RE .PP \fB\-\-latitude\fR .RS 4 Set the initial position to the specified latitude in decimal degrees\&. .RE .PP \fB\-\-longitude\fR .RS 4 Set the initial position to the specified longitude in decimal degrees\&. .RE .PP \fB\-z\fR, \fB\-\-zoom\fR .RS 4 Set the initial zoom level\&.

The file format is heavily inspired by the GtkBuilder file format: you specify the class of the GObject to build and set its properties\&. Technically, it is a XML file containing a "objects" root element\&. Inside this element, you set a collection of "object"\&. .PP Here is an example: .sp .if n \{\ .RS 4 .\} .nf Property value Property value \&.\&.\&. .fi .if n \{\ .RE .\} .PP You can find more examples in the documentation part of the distribution\&. .PP The User Configuration File Location directory is ~/\&.viking for versions up to v1\&.8\&. For new installs from v1\&.9 onwards it is ~/\&.config/viking If the legacy location exists then Viking will use that in preference to the new location\&. .PP \fBMap Source\fR. It is possible to add new map sources\&. The file is maps\&.xml in User Configuration File Location directory\&. An example of the file in the distribution doc/examples/maps\&.xml\&. The VikSlippyMapSource allows declaration of any map source working like OpenStreetMap\&. It supports the following properties: .PP id .RS 4 this is an integer and should be unique as it used to identify the map source .RE .PP name .RS 4 a string (should be unique) that is used for the OSM style cache directory name when the Map Cache directory is the default (up to v1\&.8 ~/\&.viking\-maps or v1\&.9 onwards~/\&.cache/viking) .RE .PP label .RS 4 the text displayed in the map\*(Aqs source selection dialog .RE .PP hostname .RS 4 the server\*(Aqs hostname (eg\&.

It is possible to add new new search engines for the "Go\-To" feature\&. The file is goto_tools\&.xml in User Configuration File Location directory\&. An example of the file in the distribution doc/examples/goto_tools\&.xml\&. Currently, there is a single object class available: VikGotoXmlTool\&. This feature allows one to declare any search engine using a XML format as result\&. The related properties are: .PP label .RS 4 the text displayed in the Go\-To dialog .RE .PP url\-format .RS 4 the parametrized address of the query, in the spirit of C \fBprintf\fR format, with a single "%s" field (replaced by the query string) .RE .PP lat\-path .RS 4 XML path of the latitude (eg\&. /root/parent/elem) .RE .PP lat\-attr (optional) .RS 4 name of the attribute (of previous element) containing the latitude .RE .PP lon\-path .RS 4 XML path of the longitude (eg\&. /root/parent/elem) .RE .PP lon\-attr (optional) .RS 4 name of the attribute (of previous element) containing the longiude .RE As a facility (or readability) it is possible to set both path and attribute name in a single property, like an XPath expression\&. To do so, simply set both info in lat\-path (or lon\-path) in the following format: /root/parent/elem@attribute\&. .PP \fBExternal tools\fR. It is possible to add new external tools\&. The file is external_tools\&.xml in User Configuration File Location directory\&. An example of the file in the distribution doc/examples/external_tools\&.xml\&. The VikWebtoolCenter allows one to declare any Webtool using a logic based on center coordinates and zoom level value\&. The related properties are: .PP label .RS 4 the text displayed in the menu entry .RE .PP url .RS 4 the parametrized URL to open, in the spirit of C printf format, with 2 "%s" and a "%d" fields for X, Y and Z (zoom level) (eg\&.

The related properties are: .PP id .RS 4 a string, should be unique as it used to identify the routing engine .RE .PP label .RS 4 the text displayed in the menu entry .RE .PP format .RS 4 The GPSBabel format code to interpret the service response\&. By default a GPX response is expected and processed internally\&. However if the service returns different format then GPSBabel is used to transform the text into something that Viking can understand\&. Only formats that GPSBabel supports can be used: e\&.g\&. \*(Aqgpx\*(Aq, \*(Aqkml\*(Aq, \*(Aqgtrnctr\*(Aq (for Garmin Training Center \&.tcx files), etc\&.\&.\&. .sp Use \fBgpsbabel \-\-help\fR on the command line to find out the supported file types and their codes to process them\&. .RE .PP url\-base .RS 4 the base URL of the web service (eg\&. "http://hostname/service?") .RE .PP url\-start\-ll .RS 4 the part of the URL setting the starting point location, parametrized in the spirit of C printf format, with 2 "%s" for coordinates (eg\&. "&start=%s,%s") .RE .PP url\-stop\-ll .RS 4 the part of the URL setting the end point location, parametrized in the spirit of C printf format, with 2 "%s" for coordinates (eg\&. "&stop=%s,%s") .RE .PP url\-via\-ll (optional) .RS 4 the part of the URL setting via point location, parametrized in the spirit of C printf format, with 2 "%s" for coordinates (eg\&.

"&start=%s") .RE .PP url\-stop\-dir (optional) .RS 4 the part of the URL setting the end point location for direction based routing, parametrized in the spirit of C printf format, with one "%s" for direction (eg\&. "&start=%s") .RE .PP url\-ll\-lat\-first (optional) .RS 4 The ordering of the lat/long terms in the Start, Stop and Via URL settings\&. By default this is TRUE\&. .sp For instance using Brouter services, the URL uses a pair of values which is longitude and then latitude\&. Thus setting this value to FALSE ensures the value substitution is performed in the necessary order\&. .RE .PP referer (optional) .RS 4 A URL to serve as referer for the HTTP request (eg\&. "http://hostname/") .RE .PP follow\-location (optional) .RS 4 The maximum number of redirects allowed\&. The default is 0, i\&.e\&. no redirection\&. Use \-1 for an unlimited number of redirects\&. .RE .PP \fBRemote File Datasources\fR. It is possible to add web references expected to return a file which can then be opened directly or converted via GPSBabel\&. The file is datasources\&.xml in your User Configuration File Location directory\&. An example of the file is in the source distribution doc/examples/datasources\&.xml\&. The VikWebtoolDatasource allows one to declare any URL using logic based on coordinates\&. The related properties are: .PP label .RS 4 the text displayed in the menu entry .RE .PP url .RS 4 the parametrized URL to open in the spirit of C printf format, with up to 7 "%s" values\&. e\&.g\&. http://hostname/getfile?lat=%s&lon=%s .sp The order and meaning of these parameters is given by the url_format_code below .RE .PP url_format_code .RS 4 A string describing the parametrized URL substitution parameters, each character represents how to translate each term\&. .sp B = Bottom of the current view i\&.e\&. minimum latitude .sp L = Left of the current view i\&.e\&. minimum longitude .sp T = Top of the current view i\&.e\&. maximum latitude .sp R = Right of the current view i\&.e\&. maximum longitude .sp A = center lAtitude of the current view .sp O = center lOngitude of the current view .sp Z = OSM Zoom value of the current view\&.
