rem This script will echo the IPv4 of this windows machine. E.g. 100.200.300.45
rem If passed -format-for-tomcat-context, it will echo the same with a pipe
rem symbol up front and all the . escaped with a "\". E.g. "|100\.200\.300\.45"

for /f "usebackq tokens=2 delims=:" %%a in (`ipconfig ^| find "IPv4"`) do (set result=%%a)

:: To lop off the single extra space in front of IPv4 number, end with:
::do (set result=%a& echo %result:~1%)
:: Alternative: for /f "tokens=2 delims=:" %a in ('ipconfig ^| findstr /C:"IPv4 Address"') do echo %a
:: still need to remove space up front for that too.

:: removes extra space in front
set result=%result:~1%

:: The above produces the IPv4 number, e.g. 100.200.300.45


rem Check if we're requested to format the IPv4 for the solr.xml tomcat context file
if [%1]==[] goto done
if not "%1"=="-format-for-tomcat-context" goto done
