    Fix autoninja to allow compiling one source file · f3b4f060
    Bruce Dawson authored
    This is the second attempt at fixing autoninja to allow passing '^^' to
    it to specify that ninja should build the outputs of the specified file
    instead of building that file itself. The problem is that '^' is a
    special character and when extra layers of indirection are added the
    number of '^' characters needed grows exponentially in some poorly
    understood way. The first fix attempt just quoted the arguments that
    autoninja.bat passed to autoninja.py, but that meant they came in as
    one argument. This fix expands on that by modifying autoninja.py to
    understand how to deal with the monolithic argument. With this change
    this once again works:
    
        autoninja -C out\debug_component ..\..\base\win\enum_variant.cc^^
    
    It can be convenient to have a ninja.bat file which starts goma and lets
    users keep typing the same build commands. However even with this fix
    the previously recommended ninja.bat file must be invoked with four
    '^' characters. If that is too much then the new recommended ninja.bat
    is to copy autoninja.bat and modify as needed, perhaps like this:
    
        @echo off
        call python c:\goma\goma-win64\goma_ctl.py ensure_start >nul
        FOR /f "usebackq tokens=*" %%a in (`python c:\src\depot_tools\autoninja.py "%*"`) do echo %%a & %%a
