ssl






ssl ‐ syntax/semantic language preprocessor, for parser description/generation

ssl [ −TLs ] [ −E Name ] [ −D type ] [ −h file.sst.h ] [ −t file.sst.c ] [ −l
file.lst ] [ −e file.entry ] [ −i file.ssl ]

Ssl reads the input S/SL file, and produces C code. It accepts the following
options:

−T   Trace S/SL processor execution

−L   Produce a listing of the S/SL source program with table coordinates in the
     left margin.

−s   Summarize usage of symbol and output tables.

−D Type
     Sets type of the S/SL table to Type. The default is int.

−E EnumName
     Sets name of the enumerated type list to EnumName, which will have
     nilEnumName as the first item in the enumeration (with a value of ‐1).  The
     default is no name.

−i file.ssl
     Input S/SL program file. The default is stdin.

−h file.sst.h
     Output C header file with the constant definitions for the program.  The
     default is
     ‘basename inputfile.ssl‘.sst.h.

−t file.sst.c
     Output C S/SL program table file. The default is
     ‘basename inputfile.ssl‘.sst.c.

−l file.lst
     Output listing of the S/SL program with table coordinates in the left
     margin, if requested with the ‐L option.  The default is
     ‘basename inputfile.ssl‘.lst.

−e file.entry
     Entry points file. The default is
     ‘basename inputfile.ssl‘.entry.
