+File: parameter_update.py
+Description:
+ This script searches for declarations of BlockParam, creates a variable name of the
+ form "_param_name_of_parameter" and replaces the old variable with the new one.
+
+Example:
+ (ParamExtFloat<px4::params::EKF2_GYR_NOISE>) _gyroNoise,
+ [...]
+ _gyroNoise.set(1.f);
+
+ is replaced by
+
+ (ParamExtFloat<px4::params::EKF2_GYR_NOISE>) _param_ekf2_gyr_noise,
+ [...]
+ _param_ekf2_gyr_noise.set(1.f);
+
+Usage:
+ The script needs a list of files as an input. To quickly find and feed all the file
+ that it needs to inspect, one can simply pipe the result of a ripgrep -l command as follows:
+
+ rg -l '\.[gs]et\(|px4::params::' | python parameter_update.py
