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

- --no-includes
- causes not even local include files to be used
- -I <dir>
- the directory containing the include files
- --include-headers

- --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

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

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.
