This is a modified version of Henry Spencer's "BSD" regular expression library. The original library can be found at https://github.com/garyhouston/regex. A description of Spencer's various libraries can be found at https://garyhouston.github.io/regex/ The changes in this version are: * The library name has been changed to rxspencer, the header installs into a directory rxspencer, and the man pages named accordingly, to allow easy installation as a system library on Linux without conflicting with other regex libraries. * A CMake build system, which can build either static or shared libraries, maybe even on non-Unix systems. * A few code modernizations and changes to improve portabilty, avoid compiler warnings, and improve robustness. I (Gary Houston) originally made this version with a build system based on GNU Automake and Libtool, to allow building a shared library for a project where the library needed to be dynamically loaded. The CMake scripts were contributed by Stephen Just, modified from LuaDist versions. Spencer's original license can be found in the COPYRIGHT file. The CMake scripts are licensed under the MIT license. I release all of my own changes to the public domain under the Creative Commons Zero license. Installation ============ CMake needs to be installed. To build from a Linux command line, or something compatible, within the source directory: to configure for a static library: cmake . or cmake -Drxshared=0 . to configure for a shared library: cmake -Drxshared=1 . to disable tests: cmake -DBUILD_TESTING=OFF . to disable manuals/ documentation: cmake -DINSTALL_DOCS=OFF . to build: make make install also required on Linux, after installing the shared library: ldconfig to run the tests: make test to run the tests, with output displayed: ctest -V Usage ===== Include the following header in a C program: #include <rxspencer/regex.h> Link with the library using the -lrxspencer flag, as in: gcc test.c -o test -lrxspencer The library is further described in the supplied man pages: rxspencer.3 and rxspencer.7, which are formatted at https://garyhouston.github.io/regex/regex3.html and https://garyhouston.github.io/regex/regex7.html. -- Gary Houston, ghouston@arglist.com
