echo CExec - Conditional Exec
echo.
echo Handles with custom arguments for cmder's init.bat.
echo written by xiazeyu, inspired DRSDavidSoft.
echo.
echo Usage:
echo.
echo cexec /setPath [NOT] flagName command/program [parameters]
echo.
echo /setPath Generate a global varibles %%ccall%% and %%cexec%% for
echo quicker use. Following arguments will be ignored.
echo.
echo NOT Specifies that cexec should carry out
echo the command only if the flag is missing.
echo.
echo /[flagName] Specifies which flag name is to detect. It's recommand
echo to use a pair of double quotation marks to wrap
echo your flag name to avoid exceed expectation.
echo.
echo command/program Specifies the command to carry out if the
echo argument name is detected. It's recommand to
echo use a pair of double quotation marks to
echo wrap your command to avoid exceed expectation.
echo.
echo parameters These are the parameters passed to the command/program.
echo It's recommand to use a pair of double quotation marks
echo to wrap your flag name to avoid exceed expectation.
echo.
echo Examples:
echo.
echo These examples are expected to be written in %cmder_root%/config/user-profile.cmd
echo CExec evaluates the environment varible "CMDER_USER_FLAGS" and conditionally
echo caries out actions based on flags that are passed.
echo.
echo Case 1:
echo.
echo The following command in `user_profile.cmd` would execute "notepad.exe" and continue running the `user_profile.cmd`
echo.
echo "%ccall%" "/startNotepad" "start" "notepad.exe"
echo.
echo If you pass parameter to init.bat like:
echo.
echo init.bat /startNotepad
echo.
echo Case 2:
echo.
echo The following command in `user_profile.cmd` would execute "notepad.exe" and stop running the `user_profile.cmd`
echo.
echo "%cexec%" NOT "/dontStartNotepad" "start" "notepad.exe"
echo.
echo UNLESS you pass parameter to init.bat like:
echo.
echo init.bat /dontStartNotepad
echo.
