All Rights Reserved. ugrep: a sample program demonstrating the use of ICU regular expression API. usage: ugrep [options] pattern [file ...] --help Output a brief help message -n, --line-number Prefix each line of output with the line number within its input file. -V, --version Output the program version number The program searches for the specified regular expression in each of the specified files, and outputs each matching line. Input files are in the system default (locale dependent) encoding, unless they begin with a BOM, in which case they are assumed to be in the UTF encoding specified by the BOM. Program output is always in the system's default 8 bit code page. Files: ./ugrep.c source code for the sample ./ugrep.sln Windows MSVC workspace. Double-click this to get started. ./ugrep.vcproj Windows MSVC project file. ./Makefile Makefile for Unixes. Needs gmake. To Build ugrep on Windows 1. Install and build ICU 2. In MSVC, open the workspace file icu\samples\ugrep\ugrep.sln 3. Choose a Debug or Release build. 4. Build. To Run on Windows 1. Start a command shell window 2. Add ICU's bin directory to the path, e.g. set PATH=c:\icu\bin;%PATH% (Use the path to where ever ICU is on your system.) 3. cd into the ugrep directory, e.g. cd c:\icu\source\samples\ugrep\debug 4. Run it ugrep ... To Build on Unixes 1. Build ICU. Specify an ICU install directory when running configure, using the --prefix option. The steps to build ICU will look something like this: cd <icu directory>/source runConfigureICU <platform-name> --prefix <icu install directory> [other options] gmake all 2. Install ICU, gmake install 3. Build the sample Put the install directory containing icu-config on the $PATH. This will generally be <icu install directory>/bin cd <icu directory>/source/samples/ugrep gmake To Run on Unixes cd <icu directory>/source/samples/ugrep export LD_LIBRARY_PATH=<icu install directory>/lib:.:$LD_LIBRARY_PATH ugrep ... Note: The name of the LD_LIBRARY_PATH variable is different on some systems. If in doubt, run the sample using "gmake check", and note the name of the variable that is used there. LD_LIBRARY_PATH is the correct name for Linux and Solaris.
