[TW#17863] eclipse-retup.rst: ambiguous instructions

In project properties, it says "Edit the PATH environment variable. Keep the current value, and append the path to the Xtensa toolchain that will installed as part of IDF setup (something/xtensa-esp32-elf/bin) if this is not already listed on the PATH."

Of five of us here, not one of us knows what that means. Is it added comma separated? Is "something" the $PATH$?

• It is added semicolon separated for Windows or colon separated for Linux
• "something" means full path to "xtensa-esp32-elf/bin"

In my case the PATH for Linux looks as follows:

/bin:/home/krzysztof/bin:/home/krzysztof/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/usr/games:/usr/local/games:/snap/bin:/home/krzysztof/esp/xtensa-esp32-elf/bin

Edit:
For Windows a typical PATH is provided in documentation.

Reopening as I think we can reword this section to be clearer.
