rem -------------------------------
rem Set up the pattern.  We are
rem expecting a file in the format:
rem
rem devstring devcontext# helpstring
rem
rem For example,
rem
rem   comctls 2000001 "Microsoft Windows Common Controls"
rem
rem Blank lines are acceptable, as
rem are lines beginning with the C++
rem single-line comment characters (//)

set ALPHANUM=[A-Za-z_0-9]
set ALPHA=[A-Za-z_]
set IDENTIFIER=%ALPHA%%ALPHANUM%*
set INTEGER=[0-9][0-9]*
set WS=[ ][ ]*
set WSOKAY=[ ]*
set ANY=.*

set HID_LINE=%WSOKAY%\(%IDENTIFIER%\)%WS%\(%INTEGER%\)%WS%\"\(%ANY%\)\"%WSOKAY%

rem -------------------------------
rem Okay, have SED change the above format
rem into the following formats (one format
rem for each output file
rem
rem   #define HID_devstring devcontext#
rem   #define BS_devstring "helpstring"
rem
rem Example:
rem
rem   #define HID_comctls]] 2000001
rem   #define BS_comctls "Microsoft Windows Common Controls"
rem
rem This format is needed by VBIDE.SRC and WIZARD.SRC as well
rem as all OLE controls.
rem
rem Note that comment lines at the beginning of a line
rem are carried through to the destination.  This is
rem quite intentional.

rem Remove comments that don't begin a line
%SED% "s#^\(..*\)//.*$#\1#g" < %FILE_ID% >> %FILE_TMP1%

rem
rem Add the STRINGTABLE section to the .RC file
rem

echo #include "%IncludedFile%" >> %FILE_DEST3%
echo STRINGTABLE DISCARDABLE >> %FILE_DEST3%
echo BEGIN >> %FILE_DEST3%

rem Okay, go ahead and make the transformations
%SED% "s/^%HID_LINE%$/#define HID_\1 \2/g" < %FILE_TMP1% >> %FILE_DEST1%
%SED% "s/^%HID_LINE%$/#define BS_\1  \"\3\"/g" < %FILE_TMP1% >> %FILE_DEST2%
%SED% "s/^%HID_LINE%$/        HID_\1 \& 65535 \"\3\"/g" < %FILE_TMP1% >> %FILE_DEST3%
