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.dsw Windows MSVC workspace. Double-click this to get started.
|
|
./ugrep.dsp 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.dsw
|
|
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
|
|
cd <icu directory>/source/samples/ugrep
|
|
export ICU_PREFIX= <icu install directory>
|
|
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.
