I am looking to make an install script for hifi-berry and a few other pieces of hardware. When config.txt didn't have sections, there was no risk of adding a line in the "wrong place".

With the sections (which seem like a really nice feature), adding lines to the right place strikes me as quite error prone.

Is anyone aware of an editor (before I write my own) which is capable of understanding enough structure of the config.txt to be able to add / remove / change values in the correct section(s)

e.g.

sudo config_edit --platform=pi3 --EDID=asus_monitor --add 'dtoverlay=asus_touch_screen'
sudo config_edit --add 'dtoverlay=microphone'   # add to un-filtered section

See : Conditional filters in config.txt

  • You need to explain what "correct section" means. config.txt is a simple text file, editable with any editor. See raspberrypi.org/documentation/configuration/config-txt

  • Do you mean something like sed / awk - use regular expressions to change a known value to the new value + the known value. The other way would be to replace the whole of the line with what you want - much simpler in my mind (but I'm known to be a lazy programmer).

  • @Andrew I was thinking that the new filter functionality made textual modifications difficult, as you need to track active filters, and optionally have to add filters. Finally if you add a filter, you may need to add [all] afterwards.

There is! Try using this: sudo nano /boot/config.txt

If you didn't know nano is pretty nice! It is not Vim but still good!

  • How would I use nano in an install script? I was hoping for something which would classify each line as part of the active filters, and allow me to edit only the relevant line from the input parameters.

  • Ok, sorry. I thought you wanted just to edit a file. Mar 14 at 15:14
