github-linguist including files with linguist-vendored attribute in language statistics-CodePudding

I have a github repository that is predominately C but has lots of vendor-generated C code (drivers for a microcontroller) that is completely throwing off the language statistics. I have read this page and I have created a .gitattributes file in my repository that should mark all these driver files as linguist-vendored and keep them from being included in the statistics. Although git check-attr reports the linguist-vendored attribute as being set, the github-linguist command line tool still ignores this. What am I doing wrong?

$ cat .gitattributes
STM32[[:space:]]Code/*/** linguist-vendored
STM32[[:space:]]Code/*/Core/Src/** -linguist-vendored
STM32[[:space:]]Code/*/Core/Inc/** -linguist-vendored

$ git add .gitattributes
$ git commit --amend --no-edit

$ git check-attr -a "STM32 Code/BLDC/Drivers/STM32F3xx_HAL_Driver/Src/stm32f3xx_hal.c"
STM32 Code/BLDC/Drivers/STM32F3xx_HAL_Driver/Src/stm32f3xx_hal.c: linguist-vendored: set

$ github-linguist --breakdown

...
C:
STM32 Code/BLDC/Drivers/STM32F3xx_HAL_Driver/Src/stm32f3xx_hal.c

I have also tried changing the .gitattributes file to just

STM32[[:space:]]Code/** linguist-vendored

and it still doesn't ignore the files inside.

CodePudding user response：

I suspect you may be using an old version of Linguist and/or rugged (which is what does the checking of the gitattributes); possibly the versions shipped with your OS as I can't reproduce your behaviour using the latest version which GitHub is using:
