2ugrep: a sample program demonstrating the use of ICU regular expression API.
3
4usage: ugrep [options] pattern [file ...]
5
6 --help Output a brief help message
7 -n, --line-number Prefix each line of output with the line number within its input file.
8 -V, --version Output the program version number

11The program searches for the specified regular expression in each of the
12specified files, and outputs each matching line.
13
14Input files are in the system default (locale dependent) encoding, unless they
15begin with a BOM, in which case they are assumed to be in the UTF encoding
16specified by the BOM. Program output is always in the system's default
178 bit code page.

20Files:
21 ./ugrep.c source code for the sample
22 ./ugrep.sln Windows MSVC workspace. Double-click this to get started.
23 ./ugrep.vcproj Windows MSVC project file.
24 ./Makefile Makefile for Unixes. Needs gmake.

27To Build ugrep on Windows
28 1. Install and build ICU
29 2. In MSVC, open the workspace file icu\samples\ugrep\ugrep.sln
30 3. Choose a Debug or Release build.
31 4. Build.
32
33To Run on Windows
34 1. Start a command shell window
35 2. Add ICU's bin directory to the path, e.g.
36 set PATH=c:\icu\bin;%PATH%
37 (Use the path to where ever ICU is on your system.)
38 3. cd into the ugrep directory, e.g.
39 cd c:\icu\source\samples\ugrep\debug
40 4. Run it
41 ugrep ...
42
43
44To Build on Unixes
45 1. Build ICU. Specify an ICU install directory when running configure,
46 using the --prefix option. The steps to build ICU will look something
47 like this:
48 cd <icu directory>/source
49 runConfigureICU <platform-name> --prefix <icu install directory> [other options]
50 gmake all
51
52 2. Install ICU,
53 gmake install
54
55 3. Build the sample
56 Put the install directory containing icu-config on the $PATH.
57 This will generally be <icu install directory>/bin
58 cd <icu directory>/source/samples/ugrep
59 gmake
60
61 To Run on Unixes
62 cd <icu directory>/source/samples/ugrep
63
64 export LD_LIBRARY_PATH=<icu install directory>/lib:.:$LD_LIBRARY_PATH
65 ugrep ...
66
67
68 Note: The name of the LD_LIBRARY_PATH variable is different on some systems.
69 If in doubt, run the sample using "gmake check", and note the name of
70 the variable that is used there. LD_LIBRARY_PATH is the correct name
71 for Linux and Solaris.
