[Paparazzi-devel] [feature] automatic flight plan variables

[Gautier Hattenberger]

Dear all,

A new feature have just been introduced (in master branch) in the flight 
plan language of Paparazzi: the possibility to declare some variables 
from the flight plan and to have them available in the datalink settings 
automatically.

This may be very interesting for users or developers using custom flight 
plans and that need to change some parameters such as setpoints or 
thresholds. Before that, it was required to (ab)use existing variables 
or create them on purpose (thus editing the source code). Now it can be 
done from the flight plan xml file with:

<variables>
  <variable var="my_var"/>
  ...
</variables>

The relevant commit is 
https://github.com/paparazzi/paparazzi/commit/579fdf4acd8686f18857ad65fd5b58fdf6e2eaf0 
and the 'versatile' flight plan shows an example 
(https://github.com/paparazzi/paparazzi/commit/70e867cad7d46e47ef77ddeebeb75a3a1999d66c).

The documentation with the complete options (in particular, how to have 
it accessible as a setting) is in the wiki:

Happy flight plan editing!
