Summary

raspi-config is only shipped (and only honored) on Raspberry Pi OS. The installer scripts in Raspberry-Pi-Installer-Scripts shell out to raspi-config nonint ... in a bunch of places (adafruit-pitft.py, raspi-blinka.py, raspi-spi-reassign.py, joy-bonnet.py, retrogame.py, pitft-fbcp.py, ...) to toggle SPI/I2C, set overscan, change boot behaviour, etc. On non-Pi-OS distros that share the same hardware (DietPi, Ubuntu Server on a Pi, etc.) the binary just isn't there: shell.run_command returns falsy on the missing binary and the script continues, but the tweak silently doesn't happen and the user sees a confusing command not found line.

Change

Adds Shell.run_raspi_config(args, suppress_message=False, return_output=False, run_as_user=None) as a thin wrapper around run_command:

  • Returns immediately (True, or "" when return_output=True) when is_raspberry_pi_os() is False, so callers that ignore the return value short-circuit cleanly and callers that .strip() the output still get a usable string.
  • On Raspberry Pi OS, forwards to run_command("raspi-config nonint " + args, ...) with the same kwargs.

args is the portion after raspi-config nonint — e.g. shell.run_raspi_config("do_spi 0").

Also migrates the existing Shell.set_window_manager() call (which already invokes raspi-config nonint do_wayland … directly) to use the new helper. That gives it the same non-Pi-OS short-circuit and avoids the RuntimeError("Unable to change window manager") it would otherwise raise on hosts where the binary isn't present.

Test plan

Installed the modified package in a venv and exercised run_raspi_config with Shell.run_command monkey-patched to record calls:

ScenarioResultrun_command calls observed
Pi OS, basic call: run_raspi_config('do_spi 0')returns Trueraspi-config nonint do_spi 0 ✓
Pi OS, with return_output=True, suppress_message=True: run_raspi_config('get_spi', suppress_message=True, return_output=True)returns subprocess outputraspi-config nonint get_spi with all kwargs forwarded ✓
Non-Pi-OS, basic callreturns Truenone ✓
Non-Pi-OS, return_output=Truereturns '' (so .strip() callers stay happy)none ✓

Follow-up

A companion PR against adafruit/Raspberry-Pi-Installer-Scripts (#384, currently in flight) will switch the call sites in adafruit-pitft.py over to shell.run_raspi_config(...) once this lands. Other scripts in that repo (raspi-blinka.py, raspi-spi-reassign.py, joy-bonnet.py, retrogame.py, pitft-fbcp.py) can migrate the same way.

Add Shell.run_raspi_config() that no-ops on non-Raspberry-Pi-OS
16af287
raspi-config is only shipped (and only honored) on Raspberry Pi OS,
so installer scripts that shell out to `raspi-config nonint ...` to
toggle SPI/I2C, set overscan, change boot behaviour, etc. fail
silently on DietPi, Ubuntu, and other Debian-based distros — the
binary isn't there and the configuration tweak it stood for never
happens.
Add a small helper, Shell.run_raspi_config(args, ...), that:
* Returns immediately (True, or "" when return_output=True) when
is_raspberry_pi_os() is False, so callers that ignore the return
value short-circuit cleanly and callers that .strip() the output
still get a usable string.
* On Raspberry Pi OS, forwards to run_command() with the same
suppress_message / return_output / run_as_user kwargs.
Also switch the existing Shell.set_window_manager() raspi-config call
to use the new helper so it behaves the same way on non-Pi-OS hosts
(previously it would have raised RuntimeError after failing to find
the binary).
The intent is for downstream installer scripts (adafruit-pitft.py,
raspi-blinka.py, raspi-spi-reassign.py, joy-bonnet.py, retrogame.py,
pitft-fbcp.py, ...) to switch from `shell.run_command("sudo
raspi-config nonint ...")` to `shell.run_raspi_config(...)` and
inherit the non-Pi-OS skip for free.

Gate raspi-config calls behind Shell.run_raspi_config() (fixesadafru…
053a85a
…it#321)
This repo's Python installer scripts shell out to 'raspi-config
nonint ...' for SPI/I2C toggles, overscan, boot behaviour, fan
service, etc. The raspi-config binary is only shipped (and only
honored) on Raspberry Pi OS; on DietPi, Ubuntu, and other
Debian-based distros the binary is absent and shell.run_command()
returns falsy on the missing executable, so the tweak silently
doesn't happen and the user sees a confusing 'command not found'
line mid-install.
Adafruit_Python_Shell now ships Shell.run_raspi_config(args, ...)
(adafruit/Adafruit_Python_Shell#38) which gates on
shell.is_raspberry_pi_os() and short-circuits cleanly on non-Pi-OS
hosts, returning True (or '' when return_output=True so .strip()
callers stay happy).
Migrate every raspi-config nonint call site in the repo's Python
scripts to the new helper:
* adafruit-pitft.py (6 sites: boot_behaviour, boot_splash,
boot_target, overscan x2)
* raspi-blinka.py (7 sites: i2c, spi, serial_hw, serial,
ssh, camera, disable_raspi_config_at_boot)
* raspi-spi-reassign.py (3 sites incl. get_spi with
return_output=True / .strip())
* joy-bonnet.py (2 sites: i2c, overscan)
* retrogame.py (1 site: i2c)
* pitft-fbcp.py (1 site: spi)
* rtc.py (1 site: i2c)
* adafruit_fanservice.py (1 site: fan -- previously gated only on
is_raspberry_pi(), which is true on
DietPi-on-Pi-hardware)
Closes the underlying 'non-Pi-OS distro support' gap reported in
adafruit#321. (The reporter's specific is_wayland()/loginctl complaint was
already fixed in d14339d, but the broader raspi-config-unavailable
problem on the same distro remained.)
Behavior on Raspberry Pi OS is unchanged. The leading 'sudo' on
the old run_command lines is dropped: all of these installers
already require root via require_root() (or equivalent), so the
inner sudo was redundant. Bash-only scripts in this repo
(pi-eyes.sh, arcade-bonnet.sh, rgb-matrix.sh, retrogame.sh,
spectro.sh) call raspi-config directly and are out of scope here.

Summary
raspi-config is only shipped (and only honored) on Raspberry Pi OS. The installer scripts in Raspberry-Pi-Installer-Scripts shell out to raspi-config nonint ... in a bunch of places (adafruit-pitft.py, raspi-blinka.py, raspi-spi-reassign.py, joy-bonnet.py, retrogame.py, pitft-fbcp.py, ...) to toggle SPI/I2C, set overscan, change boot behaviour, etc. On non-Pi-OS distros that share the same hardware (DietPi, Ubuntu Server on a Pi, etc.) the binary just isn't there: shell.run_command returns falsy on the missing binary and the script continues, but the tweak silently doesn't happen and the user sees a confusing command not found line.
Change
Adds Shell.run_raspi_config(args, suppress_message=False, return_output=False, run_as_user=None) as a thin wrapper around run_command:
  • Returns immediately (True, or "" when return_output=True) when is_raspberry_pi_os() is False, so callers that ignore the return value short-circuit cleanly and callers that .strip() the output still get a usable string.
  • On Raspberry Pi OS, forwards to run_command("raspi-config nonint " + args, ...) with the same kwargs.
args is the portion after raspi-config nonint — e.g. shell.run_raspi_config("do_spi 0").
Also migrates the existing Shell.set_window_manager() call (which already invokes raspi-config nonint do_wayland … directly) to use the new helper. That gives it the same non-Pi-OS short-circuit and avoids the RuntimeError("Unable to change window manager") it would otherwise raise on hosts where the binary isn't present.
Test plan
Installed the modified package in a venv and exercised run_raspi_config with Shell.run_command monkey-patched to record calls:
ScenarioResultrun_command calls observed
Pi OS, basic call: run_raspi_config('do_spi 0')returns Trueraspi-config nonint do_spi 0 ✓

Non-Pi-OS, return_output=Truereturns '' (so .strip() callers stay happy)none ✓
Follow-up
A companion PR against adafruit/Raspberry-Pi-Installer-Scripts (#384, currently in flight) will switch the call sites in adafruit-pitft.py over to shell.run_raspi_config(...) once this lands. Other scripts in that repo (raspi-blinka.py, raspi-spi-reassign.py, joy-bonnet.py, retrogame.py, pitft-fbcp.py) can migrate the same way.

Add Shell.run_raspi_config() that no-ops on non-Raspberry-Pi-OS
16af287
raspi-config is only shipped (and only honored) on Raspberry Pi OS,
so installer scripts that shell out to `raspi-config nonint ...` to
toggle SPI/I2C, set overscan, change boot behaviour, etc. fail
silently on DietPi, Ubuntu, and other Debian-based distros — the
binary isn't there and the configuration tweak it stood for never
happens.
Add a small helper, Shell.run_raspi_config(args, ...), that:
* Returns immediately (True, or "" when return_output=True) when
is_raspberry_pi_os() is False, so callers that ignore the return
value short-circuit cleanly and callers that .strip() the output
still get a usable string.
* On Raspberry Pi OS, forwards to run_command() with the same
suppress_message / return_output / run_as_user kwargs.
Also switch the existing Shell.set_window_manager() raspi-config call
to use the new helper so it behaves the same way on non-Pi-OS hosts
(previously it would have raised RuntimeError after failing to find
the binary).
The intent is for downstream installer scripts (adafruit-pitft.py,
raspi-blinka.py, raspi-spi-reassign.py, joy-bonnet.py, retrogame.py,
pitft-fbcp.py, ...) to switch from `shell.run_command("sudo
raspi-config nonint ...")` to `shell.run_raspi_config(...)` and
inherit the non-Pi-OS skip for free.

Gate raspi-config calls behind Shell.run_raspi_config() (fixesadafru…
053a85a
…it#321)
This repo's Python installer scripts shell out to 'raspi-config
nonint ...' for SPI/I2C toggles, overscan, boot behaviour, fan
service, etc. The raspi-config binary is only shipped (and only
honored) on Raspberry Pi OS; on DietPi, Ubuntu, and other
Debian-based distros the binary is absent and shell.run_command()
returns falsy on the missing executable, so the tweak silently
doesn't happen and the user sees a confusing 'command not found'
line mid-install.
Adafruit_Python_Shell now ships Shell.run_raspi_config(args, ...)
(adafruit/Adafruit_Python_Shell#38) which gates on
shell.is_raspberry_pi_os() and short-circuits cleanly on non-Pi-OS
hosts, returning True (or '' when return_output=True so .strip()
callers stay happy).
Migrate every raspi-config nonint call site in the repo's Python
scripts to the new helper:
* adafruit-pitft.py (6 sites: boot_behaviour, boot_splash,
boot_target, overscan x2)
* raspi-blinka.py (7 sites: i2c, spi, serial_hw, serial,
ssh, camera, disable_raspi_config_at_boot)
* raspi-spi-reassign.py (3 sites incl. get_spi with
return_output=True / .strip())
* joy-bonnet.py (2 sites: i2c, overscan)
* retrogame.py (1 site: i2c)
* pitft-fbcp.py (1 site: spi)
* rtc.py (1 site: i2c)
* adafruit_fanservice.py (1 site: fan -- previously gated only on
is_raspberry_pi(), which is true on
DietPi-on-Pi-hardware)
Closes the underlying 'non-Pi-OS distro support' gap reported in
adafruit#321. (The reporter's specific is_wayland()/loginctl complaint was
already fixed in d14339d, but the broader raspi-config-unavailable
problem on the same distro remained.)
Behavior on Raspberry Pi OS is unchanged. The leading 'sudo' on
the old run_command lines is dropped: all of these installers
already require root via require_root() (or equivalent), so the
inner sudo was redundant. Bash-only scripts in this repo
(pi-eyes.sh, arcade-bonnet.sh, rgb-matrix.sh, retrogame.sh,
spectro.sh) call raspi-config directly and are out of scope here.

Summary
raspi-config is only shipped (and only honored) on Raspberry Pi OS. The installer scripts in Raspberry-Pi-Installer-Scripts shell out to raspi-config nonint ... in a bunch of places (adafruit-pitft.py, raspi-blinka.py, raspi-spi-reassign.py, joy-bonnet.py, retrogame.py, pitft-fbcp.py, ...) to toggle SPI/I2C, set overscan, change boot behaviour, etc. On non-Pi-OS distros that share the same hardware (DietPi, Ubuntu Server on a Pi, etc.) the binary just isn't there: shell.run_command returns falsy on the missing binary and the script continues, but the tweak silently doesn't happen and the user sees a confusing command not found line.
Change
Adds Shell.run_raspi_config(args, suppress_message=False, return_output=False, run_as_user=None) as a thin wrapper around run_command:
  • Returns immediately (True, or "" when return_output=True) when is_raspberry_pi_os() is False, so callers that ignore the return value short-circuit cleanly and callers that .strip() the output still get a usable string.
  • On Raspberry Pi OS, forwards to run_command("raspi-config nonint " + args, ...) with the same kwargs.
args is the portion after raspi-config nonint — e.g. shell.run_raspi_config("do_spi 0").
Also migrates the existing Shell.set_window_manager() call (which already invokes raspi-config nonint do_wayland … directly) to use the new helper. That gives it the same non-Pi-OS short-circuit and avoids the RuntimeError("Unable to change window manager") it would otherwise raise on hosts where the binary isn't present.
Test plan
Installed the modified package in a venv and exercised run_raspi_config with Shell.run_command monkey-patched to record calls:
ScenarioResultrun_command calls observed
Pi OS, basic call: run_raspi_config('do_spi 0')returns Trueraspi-config nonint do_spi 0 ✓
Pi OS, with return_output=True, suppress_message=True: run_raspi_config('get_spi', suppress_message=True, return_output=True)returns subprocess outputraspi-config nonint get_spi with all kwargs forwarded ✓
Non-Pi-OS, basic callreturns Truenone ✓
Non-Pi-OS, return_output=Truereturns '' (so .strip() callers stay happy)none ✓
Follow-up
A companion PR against adafruit/Raspberry-Pi-Installer-Scripts (#384, currently in flight) will switch the call sites in adafruit-pitft.py over to shell.run_raspi_config(...) once this lands. Other scripts in that repo (raspi-blinka.py, raspi-spi-reassign.py, joy-bonnet.py, retrogame.py, pitft-fbcp.py) can migrate the same way.

Add Shell.run_raspi_config() that no-ops on non-Raspberry-Pi-OS
16af287
raspi-config is only shipped (and only honored) on Raspberry Pi OS,
so installer scripts that shell out to `raspi-config nonint ...` to
toggle SPI/I2C, set overscan, change boot behaviour, etc. fail
silently on DietPi, Ubuntu, and other Debian-based distros — the
binary isn't there and the configuration tweak it stood for never
happens.
Add a small helper, Shell.run_raspi_config(args, ...), that:
* Returns immediately (True, or "" when return_output=True) when
is_raspberry_pi_os() is False, so callers that ignore the return
value short-circuit cleanly and callers that .strip() the output
still get a usable string.
* On Raspberry Pi OS, forwards to run_command() with the same
suppress_message / return_output / run_as_user kwargs.
Also switch the existing Shell.set_window_manager() raspi-config call
to use the new helper so it behaves the same way on non-Pi-OS hosts
(previously it would have raised RuntimeError after failing to find
the binary).
The intent is for downstream installer scripts (adafruit-pitft.py,
raspi-blinka.py, raspi-spi-reassign.py, joy-bonnet.py, retrogame.py,
pitft-fbcp.py, ...) to switch from `shell.run_command("sudo
raspi-config nonint ...")` to `shell.run_raspi_config(...)` and
inherit the non-Pi-OS skip for free.

Gate raspi-config calls behind Shell.run_raspi_config() (fixesadafru…
053a85a
…it#321)
This repo's Python installer scripts shell out to 'raspi-config
nonint ...' for SPI/I2C toggles, overscan, boot behaviour, fan
service, etc. The raspi-config binary is only shipped (and only
honored) on Raspberry Pi OS; on DietPi, Ubuntu, and other
Debian-based distros the binary is absent and shell.run_command()
returns falsy on the missing executable, so the tweak silently
doesn't happen and the user sees a confusing 'command not found'
line mid-install.
Adafruit_Python_Shell now ships Shell.run_raspi_config(args, ...)
(adafruit/Adafruit_Python_Shell#38) which gates on
shell.is_raspberry_pi_os() and short-circuits cleanly on non-Pi-OS
hosts, returning True (or '' when return_output=True so .strip()
callers stay happy).
Migrate every raspi-config nonint call site in the repo's Python
scripts to the new helper:
* adafruit-pitft.py (6 sites: boot_behaviour, boot_splash,
boot_target, overscan x2)
* raspi-blinka.py (7 sites: i2c, spi, serial_hw, serial,
ssh, camera, disable_raspi_config_at_boot)
* raspi-spi-reassign.py (3 sites incl. get_spi with
return_output=True / .strip())
* joy-bonnet.py (2 sites: i2c, overscan)
* retrogame.py (1 site: i2c)
* pitft-fbcp.py (1 site: spi)
