Fix Vagrant about environment variables #vagrant
Raw
*.md

Batch file vagrant.bat sets both GEM_HOME and GEM_PATH environment variables. It would be nice of him to restore old values after finishing it's work.

Something like:

:: Save variables
SET "GEM_HOME_SAVED=%GEM_HOME%"
SET "GEM_PATH_SAVED=%GEM_PATH%"

...

and at the end of a file

...

:: Restore variables
SET "GEM_HOME=%GEM_HOME_SAVED%"
SET "GEM_PATH=%GEM_PATH_SAVED%"
SET "GEM_HOME_SAVED="
SET "GEM_PATH_SAVED="

:: Restore environment variables GEM_HOME and GEM_PATH (read from .gemrc)
::
:: Restore variables from .gemrc
:: for /f "tokens=*" %%f in ('gem env gemhome') do @set GEM_HOME=%%f
:: for /f "tokens=*" %%f in ('gem env gempath') do @set GEM_PATH=%%f

Btw: This :: thing are comments in .bat files. Nicer than REM.
