Static code analysis on the cloud? Is it possible with platformio?

Hi,
I want to simply run a static code analysis of my Platformio projects (C++ sketch/libs)

I want to launch this analysis via GitHub actions during the build process, is there something
that platformio can do to help me doing it?

Is there some integrations with platformio to the major analysis tools like SonarQube and others?

Thanks

It’s ready for use. Just use https://docs.platformio.org/en/latest/core/userguide/cmd_check.html

There is an example how to setup Github Actions and PlatformIO Core https://docs.platformio.org/en/latest/integration/ci/github-actions.html

love your PlatformIO, thanks for it Ivan and congratulations.

this is the output of the command (I runned it in the GitHub Actions environment with a config similar to the one in your docs),

    platformio check --verbose --severity=high

I don’t understand the output :

This message is triggered when the checking tool return a return-code not equal to 0

Which is weird if the Checking ... output comes that should be from cppcheck right?

When you run the verbose command, the first output should be the invocation of the tool itself, like

C:\Users\Maxi\.platformio\packages\tool-cppcheck\cppcheck --error-exitcode=1 --verbose --template="severity={severity}<&PIO&>message={message}<&PIO&>file={file}<&PIO&>line={line}<&PIO&>column={column}<&PIO&>callstack={callstack}<&PIO&>cwe={cwe}<&PIO&>id={id}" --inline-suppr --platform=unspecified --enable=warning,style,performance,portability,unusedFunction --language=c -DPLATFORMIO=40304 -DSTM32F1xx -DSTM32F105xC -DARM_MATH_CM3 -DCOMPONENT_NSPE=1 -DCOMPONENT_PSA_SRV_EMUL=1 -DCOMPONENT_PSA_SRV_IMPL=1 -DDEVICE_ANALOGIN=1 -DDEVICE_CAN=1 -DDEVICE_CRC=1 -DDEVICE_FLASH=1 -DDEVICE_I2C=1 -DDEVICE_I2CSLAVE=1 -DDEVICE_I2C_ASYNCH=1 -DDEVICE_INTERRUPTIN=1 -DDEVICE_PORTIN=1 -DDEVICE_PORTINOUT=1 -DDEVICE_PORTOUT=1 -DD

Can you manually execute that command and see if there is any error output?

found this error by manually triggering the command:
Error: Found a breaking defect ‘syntax error’ in /home/runner/.platformio/packages/framework-arduinoespressif8266/cores/esp8266/core_esp8266_features.h:44
Please note: check results might not be valid!
Try adding --skip-packages

“severity=error<&PIO&>message=syntax error<&PIO&>file=/home/runner/.platformio/packages/framework-arduinoespressif8266/cores/esp8266/core_esp8266_features.h<&PIO&>line=44<&PIO&>column=5<&PIO&>callstack=[/home/runner/.platformio/packages/framework-arduinoespressif8266/cores/esp8266/core_esp8266_features.h:44]<&PIO&>cwe=0<&PIO&>id=syntaxError”

if I add --skip-package to the command it works.

is this a platformio bug? it seems that is found blocking errors on
core_esp8266_features.h
and I don’t think that this is true.

what kind of static analysis this tool does?
what kind of errors does it detects?

thanks

Can you give a minimal project with which the problem occurs? Does this already happen on an ESP8266 Arduino Blinky sketch?

See cppcheck documentation at https://sourceforge.net/p/cppcheck/wiki/ListOfChecks/.

It’s a bug in Cppcheck tool https://trac.cppcheck.net/ticket/9685, please use -–skip-packages so PlatformIO will only check your project sources.

When using the platformIO interface in VSCode, where am I to set the setting --skip-packages?
It works if I check using the command line, but not from the IDE, as I am not able to set the flag for the pio check command emitted by the IDE.

If it’s not included in the VSCode GUI, you can also use Advanced scripting to call into pio check --skip-packages – that’s basically the example only slightly adapted. Since this looks like a bug in cppcheck that hopefully gets resolved sometime, we shouldn’t put this workaround option in the GUI…

EDIT: Use what @valeros said instead of my solution

Hi @lsangild! You can use check_skip_packages = yes in your platformio.ini.

This has just taken me 1h to find, found the commit and everything https://github.com/platformio/platformio-core/pull/3478/commits/c7d300472753153f41c8086c088d6293929b2681

but no idea how to set it so that PIO home would run it. can this be added to the documentation please!

Although it works in the command line im still getting BAD JSON in the GUI for code analysis.

You have set check_skip_packages = yes in the platformio.ini?

yes, got there in the end. It was throwing bad json, even though the pio check passed on the command line because of another error in a different [env]. some more verbose output would be good, but got it working thank you

This set in the platformio.ini causes that the libraries are checked. Shouldn’t it be the other way around?
