Uninstall Python from macOS

Remove the Python 3.8 applications directory
$ sudo rm -rf "/Applications/Python 3.8”

Remove the third-party Python 3.8 framework

$ sudo rm -rf /Library/Frameworks/Python.framework/Versions/3.8

Remove the symbolic links, in /usr/local/bin, that point to this Python version. See them using
$ ls -l /usr/local/bin | grep '../Library/Frameworks/Python.framework/Versions/3.8’

and then run the following command to remove all the links:
$ cd /usr/local/bin/
$ ls -l /usr/local/bin | grep '../Library/Frameworks/Python.framework/Versions/3.8’ | awk '{print $9}' | tr -d @ | xargs rm

Edit your shell profile file(s) to remove /Library/Frameworks/Python.framework/Versions/3.8 to your PATH environment file. Depending on which shell you use, any of the following files may have been modified: ~/.bash_login, ~/.bash_profile, ~/.cshrc, ~/.profile, ~/.tcshrc, and/or ~/.zprofile.

$vim ~/.bash_profile

Interesting article on improving Eclipse CDT Indexing

https://blogs.itemis.com/en/improving-eclipse-cdt-indexer-performance

• Performance Improvement of roughly 37%!
• It used weak references which are garbage collected as soon as heap size becomes sparse

What tense should I use in git commit message?

So far I was mostly using the past tense since it looks natural to me but the git best practices suggest us to use imperative sentence.

Example: 

My old git message:
Added IDF commands into CMake editor

New git message:
Add IDF commands into CMake editor

Where does eclipse CDT stores CMake toolchain information?

CDT stores cmake toolchain information as part of org.eclipse.cdt.cmake.core.prefs file.

/Users/kondal/runtime-EclipseApplication6/.metadata/.plugins/org.eclipse.core.runtime/.settings/org.eclipse.cdt.cmake.core.prefs

For example, here is the content of the file 

cmakeToolchains/14/__path=/Users/kondal/esp/esp-idf/tools/cmake/toolchain-esp32.cmake

cmakeToolchains/14/cdt.toolChain.id=gcc-xtensa-/Users/kondal/esp/xtensa-esp32-elf/bin/xtensa-esp32-elf-gcc

cmakeToolchains/14/cdt.toolChain.type=org.eclipse.cdt.build.gcc

cmakeToolchains/n=15

eclipse.preferences.version=1

To understand more how eclipse store preferences:
https://gnu-mcu-eclipse.github.io/developer/eclipse/runtime-preferences/

Where can I find the eclipse store preferences in the file system

Eclipse stores the preferences in the workspace of your application in the.metadata/.plugins/org.eclipse.core.runtime/.settings/ directory in the <nodePath>.prefs file

For example, for CDT build environment variables stored in here:

.metadata/.plugins/org.eclipse.core.runtime/.settings/org.eclipse.cdt.core.pref
