mso-list:l10 level1 lfo9;tab-stops:list .5in'><strong>Official Release
|
||
Snapshot:</strong><b><br>
|
||
</b>If you want to use ICU (as opposed to developing it), your best bet is
|
||
to download an official, packaged ICU version of the ICU source
|
||
code. These versions are tested more thoroughly than day-to-day
|
||
development builds of the system, and they are packaged in zip and tar
|
||
files for convenient download. These packaged files can be found at <a
|
||
href="http://oss.software.ibm.com/developerworks/opensource/icu/project/download/index.html">http://oss.software.ibm.com/developerworks/opensource/icu/project/download/index.html</a>.<br>
|
||
If packaged snapshot is named <b>ICUXXXXXX.zip </b>, XXXXXX is the release
|
||
version number.<br>
|
||
Please unzip this file. It will re-construct the source directory. </li>

|

mso-list:l10 level1 lfo9;tab-stops:list .5in'><strong>CVS Source
|
||
Repository:</strong><b><br>
|
||
</b>If you are interested in developing features, patches, or bug fixes
|
||
for ICU, you should probably be working with the latest version of the ICU
|
||
source code. You will need to check the code out of our CVS repository to
|
||
ensure that you have the most recent version of all of the files. There
|
||
are several ways to do this:</li>
|
||
<ul type=circle>
|
||
<li class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:
|
||
auto;mso-list:l10 level2 lfo9;tab-stops:list 1.0in'>WebCVS:<br>
|
||
If you want to browse the code and only make occasional downloads, you
|
||
may want to use WebCVS. It provides a convenient, web-based interface for
|
||
browsing and downloading the latest version of the ICU source code and
|
||
documentation. You can also view each file's revision history, display
|
||
the differences between individual revisions, determine which revisions
|
||
were part of which official release, and so on. </li>
|
||
<li class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:
|
||
auto;mso-list:l10 level2 lfo9;tab-stops:list 1.0in'>WinCVS:<br>
|
||
If you will be doing serious work on ICU, you should probably install a
|
||
CVS client on your own machine so that you can do batch operations
|
||
without going through the WebCVS interface. On Windows, we suggest the
|
||
WinCVS client. The following is the example instruction on how to download
|
||
ICU via WinCVS: <br>
|
||
1.Install the WinCVS client, which you can download from the WinCVS home
|
||
page. <br>
|
||
2.In the WinCVS preferences, specify your CVSRoot to be
|
||
":pserver:anoncvs@oss.software.ibm.com:/usr/cvs/icu"<br>
|
||
with the password "anoncvs". To enter the CVSRoot value, select
|
||
"Preferences" from the "Cvs Admin" pull-down menu.
|
||
Authentication should be set to "'passwd' file on the
|
||
cvs server". <br>
|
||
3.To "extract" the most recent version of ICU, select
|
||
"Checkout module" from the "Cvs Admin" menu. Specify
|
||
"icu" for the module name. </li>
|
||
<li class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:
|
||
auto;mso-list:l10 level2 lfo9;tab-stops:list 1.0in'>CVS command line:<br>
|
||
You can also check out the repository anonymously on UNIX using the
|
||
following commands, after first setting your CVSROOT to point to the ICU
|
||
repository: <br>
|
||
<br>
|
||
export CVSROOT=:pserver:anoncvs@oss.software.ibm.com:/usr/cvs/icu<br>
|

cvs login CVS password: anoncvs<br>

<h3><a name=ImportantNotes></a><u>Important Installation Notes </u></h3>
|
||
|
||
<p><strong>Win32 Platform</strong></p>
|
||
|
||
<p>If you are building on the Win32 platform, it is important that you
|
||
understand a few build details: </p>
|
||
|
||
<p><u>DLL directories and the PATH setting:</u> As delivered, the International
|
||
Components for Unicode build as several DLLs. These DLLs are placed in the
|
||
directories "icu\bin\Debug" and "icu\bin\Release".
|
||
You must add either of these directories to the PATH environment variable in
|
||
your system, or any executables you build will not be able to access
|
||
International Components for Unicode libraries. Alternatively, you can copy the
|
||
DLL files into a directory already in your PATH, but we do not recommend this
|
||
-- you can wind up with multiple copies of the DLL, and wind up using the wrong
|
||
one. </p>
|
||
|
||
<p><u>To change your PATH:</u> Do this under NT by using the System
|
||
control panel. Pick the "Environment" tab, select the variable PATH
|
||
in the lower box. In the "value" box, append the string
|
||
";drive:\...\icu\bin\Debug" at the end of the path string. If
|
||
there is nothing there, just type in "drive:\...\icu\bin\Debug".
|
||
Click the Set button, then the Ok button. </p>
|
||
|
||
<p><u>Link with Runtime libraries:</u> All the DLLs link with the C runtime
|
||
library "Debug Multithreaded DLL" or "Multithreaded DLL."
|
||
(This is changed through the Project Settings dialog, on the C/C++ tab, under
|
||
Code Generation.) It is important that any executable or other DLL you build
|
||
which uses the International Components for Unicode DLLs links with these
|
||
runtime libraries as well. If you do not do this, you will seemingly get memory
|
||
errors when you run the executable. <br>
|
||
</p>
|
||
|
||
<p><strong>OS/390 Platform</strong></p>
|
||
|
||
<p>If you are building on the OS/390 UNIX System Services platform, it is
|
||
important that you understand a<br>
|
||
few details. <br>
|
||
<br>
|
||
The gnu utilities gmake and gzip/gunzip are needed and can be obtained for
|
||
OS/390 from<br>
|
||
www.mks.com. Search for os/390, register, and follow download directions. <br>
|
||
<br>
|
||
DLL directories and the LIBPATH setting: The ICU dlls libicu-i18n and
|
||
libicu-uc.dll should be added<br>
|
||
to the LIBPATH environment variable concatenation.<br>
|
||
<br>
|
||
OS/390 supports both native S/390 hexadecimal floating point and, with Version
|
||
2.6 and later, IEEE binary<br>
|
||
floating point. This is a compile time option. Applications built with IEEE
|
||
should use ICU dlls that are<br>
|
||
built with IEEE (and vice versa). The environment variable IEEE390=1 will cause
|
||
the OS/390 version<br>
|
||
of ICU to be built with IEEE floating point. The default is native hexadecimal
|
||
floating point. <br>
|
||
<br>
|
||
The makedep executable is shipped with ICU for use with the OS/390 ICU build
|
||
process. The PATH<br>
|
||
environment variable should be updated to contain the location of this
|
||
executable prior to build.<br>
|
||
Alternatively, makedep may be moved into an existing PATH directory.<br>
|
||
<br>
|
||
When running the test suite, the TZ environment variable should be set to
|
||
export TZ="PST8PDT" so<br>
|
||
that time zone comparisons are correct.</p>
|
||
|
||
<p><a name=OS400><strong>OS/400 Platform</strong></a></p>
|
||
|
||
ICU Reference Release 1.4.0 contains partial support for the 400
|
||
platform, but additional work by the user is currently needed to get
|
||
it to build completely.
|
||
A future release of the ICU should work out-of-the-box
|
||
under OS/400.

In common/ucnv.c and common/unistr.c (search for U_MAX_PTR), there are

following: </p>
|
||
|
||
<p style='margin-right:.5in;margin-left:.5in'>1. Create a file containing the

key-value pairs which value you are overriding from the parent locale data

||
".txt". We recommend you copy parent file and change the values <br>
|
||
that need to be changed, remove all other key-pairs. Be sure
|

|

|

<p>Adding resource bundle data to your application is quite simple: </p>
|
||
|
||
<p>Create resource bundle files with the right format and names in a directory
|
||
for resource bundles you create in your application directory tree.(for more

||
href="http://www.ibm.com/java/education/international-unicode/unicodec.html">resource
|
||

|
||
Please note that resource bundle tag names should contain only invariant 7-bit
|
||
ASCII characters (e.g. ones from the following set: A-Z, a-z, 0-9, <SP>,
|
||
", %, &, `, (, ), *, +, ,, -, ., /, :, ;, <, =, >, ?, _).<br>
|

Use that same directory name (absolute path) when instantiating a resource

bundle at run time.</p>
|
||
|
||
<h3><a name=WhereCollation></a><u>Where Collation Data is stored</u></h3>
|
||
|
||
<p>Collation data is stored in a single directory on a local disk. Each
|
||
locale's data is stored in a corresponding ASCII text file indicated by a
|
||
"CollationElements" tag . For instance, the data for de_CH is stored
|
||
with a tag "CollationElements" in a file named "de_CH.txt".
|
||
Reading the collation data from these files can be time-consuming, especially
|
||
for large pieces of data that occur in languages such as Japanese. For this
|
||
reason, the Collation Framework implements a second file format, a
|
||
performance-optimized, non-portable, binary format. These binary files are
|
||
generated automatically by the framework the first time a collation table is
|
||
parsed. They have names of the form "de_CH.col". Once the files are
|
||
generated by the framework, future loading of those collations occur from the
|
||
binary file, rather than the text file, at much higher speed. </p>
|
||
|
||
<p>In general, you don't have to do anything special with these files. They can
|
||
be generated directly by using the "gencol" tool. In addition,
|
||
they can also be generated and used automatically by the framework, without
|
||
intervention on your part. However, there are situations in which you will have
|
||
to regenerate them. To do so, you must manually delete the ".col"
|
||
files from your collation data directory and re-run the gencol tool.</p>
|
||
|
||
<p>You will need to regenerate your ".col" files in the following
|
||
circumstances: </p>

(e.g., char*) such as ISO 8859-1 to and from Unicode. The objective is to
|
||
provide clean, simple, reliable, portable and adaptable data structures and
|
||
algorithms to support the International Components for Unicode's character
|
||
codeset Conversion APIs. The conversion data in the library originated from the

||
NLTC lab in IBM. The IBM character set conversion tables are publicly available
|
||
in the published IBM document called "CHARACTER DATA REPRESENTATION
|
||
ARCHITECTURE - REFERENCE AND REGISTRY". The character set conversion
|
||
library includes single-byte, double-byte and some UCS encodings to and from Unicode.

<h3><a name=ProgrammingNotes></a><u>Programming Notes</u></h3>
|
||
|
||
<h4><u>Reporting Errors</u></h4>
|
||
|
||
<p>In order for the code to be portable, only a subset of the C++ language that
|
||
will compile correctly on even the oldest of C++ compilers (and also to provide
|
||
a usable C interface) can be used in the implementation, which means that
|
||
there's no use the C++ exception mechanism in the code. </p>
|
||
|
||
<p>After considering many alternatives, the decision was that every function
|
||
that can fail takes an error-code parameter by reference. This is always the
|
||
last parameter in the function’s parameter list. The ErrorCode type is defined
|
||
as a enumerated type. Zero represents no error, positive values represent
|
||
errors, and negative values represent non-error status codes. Macros were
|
||
provided, SUCCESS and FAILURE, to check the error code. </p>
|
||
|
||
<p>The ErrorCode parameter is an input-output parameter. Every function tests
|
||
the error code before doing anything else, and immediately exits if it’s a
|
||
FAILURE error code. If the function fails later on, it sets the error code
|
||
appropriately and exits without doing any other work (except, of course, any
|
||
cleanup it has to do). If the function encounters a non-error condition it
|
||
wants to signal (such as "encountered an unmapped character" in
|
||
transcoding), it sets the error code appropriately and continues. Otherwise,
|
||
the function leaves the error code unchanged. </p>
|
||
|
||
<p>Generally, only functions that don’t take an ErrorCode parameter, but call
|
||
functions that do, have to declare one. Almost all functions that take an
|
||
ErrorCode parameter and also call other functions that do merely have to
|
||
propagate the error code they were passed down to the functions they call.
|
||
Functions that declare a new ErrorCode parameter must initialize it to
|
||
ZERO_ERROR before calling any other functions. </p>
|
||
|
||
<p>The rationale here is to allow a function to call several functions (that
|
||
take error codes) in a row without having to check the error code after each
|
||
one. [A function usually will have to check the error code before doing any
|
||
other processing, however, since it is supposed to stop immediately after
|
||
receiving an error code.] Propagating the error-code parameter down the call
|
||
chain saves the programmer from having to declare one everywhere, and also
|
||
allows us to more closely mimic the C++ exception protocol. </p>
|
||
|
||
<h4><u>C Function and Data Type Naming</u></h4>
|
||
|
||
<p><b>Function names.</b> If a function is identical (or almost identical) to
|
||
an ANSI or POSIX function, we give it the same name and (as much as possible)
|
||
the same parameter list. A "u" is prepended onto the beginning of the
|
||
name. </p>
|
||
|
||
<p>For functions that exist prior to version 1.2.1, that the function name
|
||
should begin with a lower-case "u". After the "u" is a
|
||
short code identifying the subsystem it belongs to (e.g., "loc",
|
||
"rb", "cnv", "coll", etc.). This code is
|
||
separated from the actual function name by an underscore, and the actual
|
||
function name can be anything. For example, </p>

|

|

|
||
style='margin-top:0in;margin-right:.5in;margin-bottom:0in;margin-left:.5in;
|
||
margin-bottom:.0001pt'><span style='font-size:7.5pt'> */<o:p></o:p></span></pre><pre
|
||
style='margin-top:0in;margin-right:.5in;margin-bottom:0in;margin-left:.5in;
|
||
margin-bottom:.0001pt'><span style='font-size:7.5pt'>int32_t doSomething( /* input params */, UChar* result,<o:p></o:p></span></pre><pre
|
||
style='margin-top:0in;margin-right:.5in;margin-bottom:0in;margin-left:.5in;
|
||
margin-bottom:.0001pt'><span style='font-size:7.5pt'> int32_t maxResultSize, UErrorCode* err);</span></pre>
|
||
|
||
<p>In this sample, if the actual result doesn’t fit in the space available in <span
|
||
style='font-size:10.0pt;font-family:"Courier New"'>maxResultSize</span>, this
|
||
function returns the amount of space necessary to hold the result, and result
|
||
holds as many characters of the actual result as possible. If you don’t care
|
||
about this, no further action is necessary. If you <i>do </i>care about the
|
||
truncated characters, you can then allocate a buffer on the heap of the size
|
||
specified by the return value and call the function again, passing <i>that </i>buffer’s
|
||
address for result. </p>
|
||
|
||
<p>All preflighting functions have a fill-in <span style='font-size:10.0pt;
|
||
font-family:"Courier New"'>ErrorCode</span> parameter (and follow the normal <span
|
||
style='font-size:10.0pt;font-family:"Courier New"'>ErrorCode</span> rules),
|
||
even if they are not currently doing so. Buffer overflow would be treated as a
|
||
FAILURE error condition, but would <i>not</i> be reported when the caller
|
||
passes in NULL for <span style='font-size:10.0pt;font-family:"Courier New"'>actualResultSize</span>
|
||
(presumably, a NULL for this parameter means the client doesn’t care if he got
|
||
a buffer overflow). All other failing error conditions will overwrite the
|
||
"buffer overflow" error, e.g. <span style='font-family:"Courier New"'>MISSING_RESOURCE_ERROR</span>
|
||
etc..</p>
|
||
|
||
<h4><u>Arrays as return types</u></h4>
|
||
|
||
<p>Returning an array of strings is fairly easy in C++, but very hard in C.
|
||
Instead of returning the array pointer directly, we opted for an iterative
|
||
interface instead: split the function into two functions. One returns the
|
||
number of elements in the array, and the other one returns a single specified
|
||
element from the array.</p>
|
||
|
||
<pre style='margin-top:0in;margin-right:.5in;margin-bottom:0in;margin-left:
|
||
.5in;margin-bottom:.0001pt'><span style='font-size:7.5pt'>int32_t countArrayItems(/* params */);<o:p></o:p></span></pre><pre
|
||
style='margin-top:0in;margin-right:.5in;margin-bottom:0in;margin-left:.5in;
|
||
margin-bottom:.0001pt'><span style='font-size:7.5pt'>int32_t getArrayElement(int32_t elementIndex, /* other params */,<o:p></o:p></span></pre><pre
|
||
style='margin-top:0in;margin-right:.5in;margin-bottom:0in;margin-left:.5in;
|
||
margin-bottom:.0001pt'><span style='font-size:7.5pt'> UChar* result, int32_t maxResultSize, UErrorCode* err);</span></pre>
|
||
|
||
<p>In this case, iterating across all the elements in the array would amount to
|
||
a call to the count() function followed by multiple calls to the getElement()
|
||
function. </p>
|
||
|
||
<pre style='margin-top:0in;margin-right:.5in;margin-bottom:0in;margin-left:
|
||
.5in;margin-bottom:.0001pt'><span style='font-size:7.5pt'>for (i = 0; i < countArrayItems(...); i++) {<o:p></o:p></span></pre><pre
|
||
style='margin-top:0in;margin-right:.5in;margin-bottom:0in;margin-left:.5in;
|
||
margin-bottom:.0001pt'><span style='font-size:7.5pt'> UChar element[50];<o:p></o:p></span></pre><pre
|
||
style='margin-top:0in;margin-right:.5in;margin-bottom:0in;margin-left:.5in;
|
||
margin-bottom:.0001pt'><span style='font-size:7.5pt'> getArrayItem(i, ..., element, 50, &err);<o:p></o:p></span></pre><pre
|
||
style='margin-top:0in;margin-right:.5in;margin-bottom:0in;margin-left:.5in;
|
||
margin-bottom:.0001pt'><span style='font-size:7.5pt'> /* do something with element */<o:p></o:p></span></pre><pre

|
||
margin-bottom:.0001pt'><span style='font-size:7.5pt'>}</span></pre>
|
||
|
||
<p>In the case of the resource bundle <span style='font-family:"Courier New"'>ures_XXXX</span>
|
||
functions returning 2-dimensional arrays, the getElement() function takes both
|
||
x and y coordinates for the desired element, and the count() function returns
|
||
the number of arrays (x axis). Since the size of each array element in
|
||
the resource 2-D arrays should always be the same, this provides an easy-to-use
|
||
C interface. </p>
