[Paparazzi-devel] New path instruction

[Pascal Brisset]

Hi,

answer to an old request (I cannot find it): A <path/> instruction has 
been added to the flight plan language to fly over a list of waypoints. 
It is simply preprocessed into a sequence of <go/> instructions. Example 
in basic.xml:

   <block name="Path 1,2,S1,S2,STDBY" strip_button="Path 
(1,2,S1,S2,STDBY)" strip_icon="path.png">
     <path wpts="1,2 S1"/>
     <path wpts="S1, S2 STDBY" approaching_time="1" pitch="auto" 
throttle="0.4"/>
     <deroute block="Standby"/>
   </block>

The list separaror is the regular expression "[ \t,]+" (at least one 
space, tab or comma). Extra standard attributes are allowed.
The translation produces here

       <go from="1" hmode="route" wp="2" wpts="1,2 S1" no="0"/>
       <go from="2" hmode="route" wp="S1" wpts="1,2 S1" no="1"/>
       <go from="S1" hmode="route" wp="S2" approaching_time="1" 
throttle="0.4" pitch="auto" wpts="S1, S2 STDBY" no="2"/>
       <go from="S2" hmode="route" wp="STDBY" approaching_time="1" 
throttle="0.4" pitch="auto" wpts="S1, S2 STDBY" no="3"/>

and it is what you will see in the GCS.

PS: No, it is not possible to dynamically define the waypoints list from 
the GCS during the flight :-)
