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::' -tcpp | python parameter_update.py
