NAME

       spatch - apply a semantic patch file to a set of C files

SYNOPSIS

       spatch --sp-file <SP> <files> [-o <outfile> ] [--iso-file <iso> ] [ options ]

DESCRIPTION

       spatch  is a program matching and transformation tool for C.  The programmer describes the
       code to match and the transformation to perform as a semantic patch, which  looks  like  a
       standard patch, but can transform multiple files at any number of code sites.

       Further information about spatch is available at http://coccinelle.lip6.fr/.

       Semantic   patch   examples   can   be  found  at  http://coccinellery.org/,  and  at  the
       scripts/coccinelle directory of the Linux Kernel source code.

OPTIONS

       Here is a summary of the most commonly used options:

       --sp-file <file>
              the semantic patch file

       --dir <dir>
              process all files in directory recursively

       --iso-file <file>
              (default=@SHAREDIR@/standard.iso)

       --macro-file <file>
              (default=@SHAREDIR@/standard.h)

       --debug
              print some information to help debug the matching process

       --all-includes
              causes all available include files to be used

       --no-includes
              causes not even local include files to be used

       -I <dir>
              the directory containing the include files

       --include-headers
              process header files independently

       --use-glimpse
              works with --dir, use information generated by glimpseindex

       -o <file>
              the output file. If none is specified, a patch is generated on the standard output

       --in-place
              do the modification on the file directly

       --out-place
              store modifications in a .cocci_res file

       --version
              show the version of spatch

       --date show the date on which spatch was compiled

       --shorthelp
              see short list of options

       --longhelp
              see all the available options in different categories

       -help, --help
              show summary of options.

EXAMPLES

         ./spatch --sp-file foo.cocci foo.c

       Apply the semantic patch foo.cocci to the C file foo.c.  The  semantic  patch  is  applied
       modulo a set of isomorphisms contained in standard.iso (standard.iso is by default located
       in @SHAREDIR@/standard.iso).  A patch showing the effect of the application, if any,  will
       be generated on the standard output.

         ./spatch --sp-file foo.cocci foo.c -o /tmp/newfoo.c

       The same as the above, except that a modified version of foo.c is stored in /tmp/newfoo.c.

       It is also possible to apply spatch to all of the C files in a directory:

         ./spatch --cocci-file foo.cocci --dir foodir

       If  the  semantic  patch is not working as expected, the option --debug shows selection of
       information about the application of a semantic patch to a file or directory.
