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/.
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=/usr/share/coccinelle/standard.iso)
-macro_file <file>
(default=/usr/share/coccinelle/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
/usr/share/coccinelle/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.
