DESCRIPTION

       This manual page documents briefly the styx, stypp, stydoc, ctoh, lim_test and  pim_test        commands.
       It  was  written  for  the  Debian GNU/Linux distribution because the original programs don't have manual
       pages, but have documentation in HTML format (see below).

       styx translates token and syntax descriptions contained in  $SPESTYX/language.sty  yielding  scanner  and
       parser tables as well as a functional interface to the abstract derivation tree.

       stypp is sort of a ``pretty printer'' for source files written in a styx-defined language. Furthermore it
       can be used to port source files, provided source and target languages have equivalent abstract syntax.

       stydoc generates HTML reference documentation for a grammar specified in grammarfile using a template.

       ctoh is used to create header files from C sources generated by styx.  It  is  taken  from  the  upstream
       author's  own  project  development  environment  where  source  files  are  written in a manner allowing
       interface definitions to be automatically generated.

       ptm_img translates a source file specified by the FileName option to a  binary  image.  If  the  FileName
       option is omitted, the image file must exist and the program writes the derivation tree to stdout.

       lim_test  uses  a scanner image file for language to scan the source in filename writing the token stream
       to stdout.

       pim_test uses scanner and parser image files for language to parse the source  in  filename  writing  the
       derivation tree to stdout.

ENVIRONMENT

       Upstream  authors use non-standard conventions for command-line options and environment variables, to the
       effect that the latter are best viewed as options which default to the value  of  the  identically  named
       environment variable if not specified.

       For styx, SPESTYX is the search path for language specifications (language.sty), scanner and parser image
       files are located using BINSTYX while the location of generated C code is determined by GENSTYX.

       stypp, stydoc, ptm_img, lim_test and pim_test use BINSTYX  to  locate  scanner  and  parser  image  files
       language.lim and language.pim.

SEE ALSO

       The  programs  are documented fully in The Styx Handbook available in the source distribution in LinuxDoc
       and HTML format. On Debian GNU/Linux systems the documentation is contained in the styx-doc package.
