User messages

This draft describes how to insert new messages in the conf/messages.xml file.

The basic idea here is to write new messages into a user file (user_messages.xml) and keep the standard messages into a system file (paparazzi_messages.xml), and merge them into messages.xml.

Installation

  • First of all, we copy the content of the messages.xml into paparazzi_messages.xml 
cd conf
cp messages.xml paparazzi_messages.xml
  • We download and build the merge_messages software into the sw/tools directory: 
cd ../sw/tools
wget http://www.recherche.enac.fr/~gph/planning/merge_messages.ml
wget http://www.recherche.enac.fr/~gph/planning/merge_messages.patch
patch -p0 < merge_messages.patch
make merge_messages.out

Usage

  • We write into the file conf/user_messages.xml the new messages respecting to the messages.dtd, except for the ID (which will be rewritten). You can find such an example here
  • The merge_messages.out regenerates all messages with valid ID, and print the XML output on the stdout. 
sw/tools/merge_messages > conf/messages.xml
