It is also a very capable engine,\nsupporting most common regular expression syntax and many useful\ncommand line options.   \n\nicgrep 1.0 is designed to offer substantial Unicode support, meeting\nall the Unicode Level 1 requirements of UTS #18, the Unicode\nTechnical Standard for regular expressions. \n\nNormal usage to find lines in a file f matching a regexp r is:\nicgrep r f\n\nTo produce a count of matching lines only, use the command:\nicgrep -c r f\n\nTo read the regexp to be matched from file regexpf use the command:\n\nicgrep -f regexpf f\n\nSee http://parabix.costar.sfu.ca/wiki/ICgrep for more information.\n\nBUILD\n\nTo build icgrep, you need an installed LLVM system providing the\ncore libraries.  The distribution includes a suitable source\ncode version of LLVM.   \n\nTo build LLVM,\n(L1) open a terminal window and cd to the llvm-build directory\n(L2) enter the following command to build the makefiles\ncmake -DCMAKE_INSTALL_PREFIX=../libllvm -DLLVM_TARGETS_TO_BUILD=X86 -DLLVM_BUILD_TOOLS=OFF -DLLVM_BUILD_EXAMPLES=OFF -DCMAKE_BUILD_TYPE=Release -DCMAKE_CXX_COMPILER:FILEPATH=/usr/bin/clang++ -DCMAKE_C_COMPILER:FILEPATH=/usr/bin/clang ../llvm-3.8.0.src\n(L3) Still in the llvm-build directory, enter the commands \"make\" and then \"make install\"\n\nUsing the installed LLVM, building icgrep uses the CMake build\nsystem generator.\n(IC1)  open a terminal window and cd to the icgrep-build directory\n(IC2)  enter the following command to build the makefiles\ncmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_CXX_COMPILER:FILEPATH=/usr/bin/clang++ -DCMAKE_C_COMPILER:FILEPATH=/usr/bin/clang ../icgrep\n(IC3) Enter the command \"make\"\n\nLLVM files are governed by the LLVM Release License in LLVM-LICENSE.txt.\nicgrep is governed by Open Software License 3.0 in OSL-3.0.txt.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fxhacker%2Ficgrep-devel","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fxhacker%2Ficgrep-devel","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fxhacker%2Ficgrep-devel/lists"}
