<h1>UnicodeTools</h1>
<p>This file provides instructions for building and running the UnicodeTools, which<br>
can be used to:</p>
<ul>
<li>build the Derived Unicode files in the UCD (Unicode Character Database),</li>
<li>build the transformed UCA (Unicode Collation Algorithm) files needed by ICU.</li>
<li>run consistency checks on beta releases of the UCD and the UCA.</li>
<li>build 4 chart folders on the unicode site</li>
</ul>
<p><font color="#FF0000"><b>WARNING!!</b></font></p>
<ul>
<li>This is NOT production level code, and should never be used in programs.</li>
<li>The API is subject to change without notice, and will not be maintained.</li>
<li>The source is uncommented, and has many warts; since it is not production code, it has not
been worth the time to clean it up.</li>
<li>It will probably not work on Unix or Mac without changing the file separator.</li>
<li>Currently it uses hard-coded directory names.</li>
<li>The contents of multiple versions of the UCD must be copied to a local directory, as described
below.</li>
</ul>
<h2>Instructions:</h2>
<h3>0. You will need to get ICU4J on your system, using CVS.</h3>
<p>The rest of this will assume that you have set up CVS so that you load the ICU4J project into
C:\ICU4J<br>
<br>
You need both the main icu4j and a subproject called unicodetools. See:
<a href="http://www.ibm.com/software/globalization/icu/repository.jsp">
http://www.ibm.com/software/globalization/icu/repository.jsp</a>. Inside unicodetools, look at com/ibm/text. The
main directories of interest are UCD, UCA and utility.</p>
<h4>0a. If you are using Eclipse for your IDE, look at the instructions on
<a href="http://icu.sourceforge.net/docs/eclipse_howto/eclipse_howto.html">
http://icu.sourceforge.net/docs/eclipse_howto/eclipse_howto.html</a> </h4>
<p>Set up Eclipse to build two projects: ICU4J and UnicodeTools:<br>
<br>
<b>Project Name: </b>ICU4J<br>
<b>Directory: </b>C:\ICU4J\icu4j<br>
<b>Default output folder = </b>ICU4J/classes<br>
<br>
<b>Project Name: </b>unicodetools<br>
<b>Create project from existing source: </b>C:\ICU4J\unicodetools<br>
<b>Default Output Folder: </b>unicodetools/classes<br>
<br>
After Eclipse is set up with these, exclude certain files from unicodetools:<br>
<br>
Right-Click UnicodeTools &gt; Properties &gt; Java Build Path &gt; Exclusions<br>
com/ibm/rbm/<br>
com/ibm/text/utility/UnicodeMapInt.java<br>
com/ibm/text/utility/TestUtility.java<br>
com/ibm/text/UCD/GenerateThaiBreaks-old.java/<br>
com/ibm/text/UCD/ProcessUnihan.java/<br>
com/ibm/text/UCA/WriteHTMLCollation.java/<br>
<br>
UnicodeTools must also include the ICU4J project, with<br>
<br>
Right-Click UnicodeTools &gt; Properties &gt; Java Build Path &gt; Projects</p>
<h3>1. In UCD, you must edit UCD_Types.java at the top, to set the directories for the build:</h3>
<p>public static final String DATA_DIR = &quot;C:\\DATA\\&quot;;<br>
public static final String UCD_DIR = BASE_DIR + &quot;UCD\\&quot;;<br>
public static final String BIN_DIR = DATA_DIR + &quot;BIN\\&quot;;<br>
public static final String GEN_DIR = DATA_DIR + &quot;GEN\\&quot;;<br>
<br>
Make sure that each of these directories exist. Also make sure that the following<br>
exist:<br>
<br>
&lt;GEN_DIR&gt;/DerivedData<br>
&lt;GEN_DIR&gt;/DerivedData/ExtractedProperties<br>
&lt;UCD_DIR&gt;/EXTRAS-Update</p>
<h3>2. Download all of the UnicodeData files for each version into UCD_DIR.</h3>
<p>The folder names must be of the form: &quot;3.2.0-Update&quot;, so rename the folders on the<br>
Unicode site to this format. I<span style="background-color: #FFFF00">f the
folder contains ucd, then make the contents of that directory be the contents of
the x.x.x-Update directory. That is, each directory will directly contain files
like PropList....txt</span></p>
<h4>2a Ensure Complete Release</h4>
<p>If you are downloading any &quot;incomplete&quot; release (one that does not contain a complete set of data
files for that release, you need to also download the previous complete release). Most of the N.M-Update
directoriess are complete, *except*:</p>
<p>4.0-Update, which does not contain a copy of Unihan.txt and some other files<br>
3.1-Update, which does not contain a copy of BidiMirroring.txt</p>
<p>Also, make the following changes to UnicodeData for 1.1.5:</p>
<p><b>Delete</b></p>
<pre>3400;HANGUL SYLLABLE KIYEOK A;Lo;0;L;1100 1161;;;;N;;;;;
...
4DFF;HANGUL SYLLABLE MIEUM WEO RIEUL-THIEUTH;Lo;0;L;1106 116F 11B4;;;;N;;;;;
4E00;<cjk IDEOGRAPH REPRESENTATIVE>;Lo;0;L;;;;;N;;;;;</pre>
<p><b>Add:</b></p>
<pre>4E00;<cjk Ideograph, First>;Lo;0;L;;;;;N;;;;;
9FA5;<cjk Ideograph, Last>;Lo;0;L;;;;;N;;;;;
E000;<private Use, First>;Co;0;L;;;;;N;;;;;
F8FF;<private Use, Last>;Co;0;L;;;;;N;;;;;</pre>
<p><b>And from a late version of Unicode, add:</b></p>
<pre>F900;CJK COMPATIBILITY IDEOGRAPH-F900;Lo;0;L;8C48;;;;N;;;;;
...
FA2D;CJK COMPATIBILITY IDEOGRAPH-FA2D;Lo;0;L;9DB4;;;;N;;;;;</pre>
<h4>2b. UCA data</h4>
<p>If you are building any of the UCA tools, you need to get a copy of the UCA data file<br>
from http://www.unicode.org/reports/tr10/#AllKeys. The default location for this is:<br>
<br>
BASE_DIR + &quot;Collation\allkeys&quot; + VERSION + &quot;.txt&quot;.<br>
<br>
If you have it in a different location, change that value for KEYS in UCA.java, and <br>
the value for BASE_DIR</p>
<h4>2c. Here is an example of the default directory structure with files. All of
the yellow ones should exist</h4>
<pre>C://DATA/
BIN/
<span style="background-color: #FFFF00"> Collation/
allkeys-3.1.1.txt
</span>
GEN/
DerivedData/
<span style="background-color: #FFFF00"> </span><span style="background-color: #FFFF00">UCD/
3.0.0-Update/
Unihan-3.2.0.txt
...
3.0.1-Update/
...
3.1.0-Update/
...
3.1.1-Update/
...
3.2.0-Update/
...
4.0.0-Update/
ArabicShaping-4.0.0d14b.txt
BidiMirroring-4.0.0d1b.txt
...
EXTRAS-Update/</span></pre>
<h3>3. Versions</h3>
<p>All of the following have &quot;version X&quot; in the options you give to Java (either on the&nbsp;
command line, or in the Eclipse 'run' options. If you want a specific version like 3.1.0, then you
would write &quot;version 3.1.1&quot;. If you want the latest version (4.1.0), you can omit the &quot;version X&quot;.</p>
<h3>4. Building Files</h3>
<ol>
<li><b>Setup</b><ol>
<li>In Eclipse, open the Package Explorer (Use Window&gt;Show View if you
don't see it)</li>
<li>Open UnicodeTools<ul>
<li>com.ibm.text.UCD<ul>
<li>MakeUnicodeFiles.<span style="background-color: #FFFF00">txt</span><p>This file drives the production of
the derived Unicode files. The first three lines contain
parameters that you may want to modify at some times:</p>
<pre>Generate: <b>.*script.*</b> <i>// this is a regular expression. Use .* for all files</i>
DeltaVersion: <b>10</b> <i> // This gets appended to the file name. Pick 1+ the highest value in Public</i>
CopyrightYear: <b>2006</b> <i> // Pick the current year</i></pre>
</li>
</ul>
</li>
</ul>
</li>
<li>Open in Package Explorer
<ul>
<li>com.ibm.text.UCD<ul>
<li>Main</li>
</ul>
</li>
</ul>
</li>
<li>Run&gt;Run As...<ol>
<li>Choose Java Application<ul>
<li>it will fail, don't worry; you need to set some parameters.</li>
</ul>
</li>
</ol>
</li>
<li>Run&gt;Run...<ul>
<li>Select the Arguments tab, and fill in the following<ul>
<li>Program arguments:<pre>build 5.0<span style="background-color: #FFFF00">.0</span> MakeUnicodeFiles</pre>
</li>
<li>VM arguments:
<pre>-Xms512m -Xmx512m</pre>
</li>
</ul>
</li>
<li>Close and Save</li>
</ul>
</li>
</ol>
</li>
<li><b>Run</b><ol>
<li>You'll see it build the 5.0 files, with something like the following
results:<pre>Writing UCD_Data5.0.0
Data Size: 109,802
Wrote Data 109802</pre>
</li>
<li>For each version, the tools build a set of binary data in BIN that
contain the information for that release. This is done automatically, or
you can manually do it with the Program Arguments<pre>version X build</pre>
<p>This builds an compressed format of all the UCD data (except blocks
and Unihan) into the BIN directory. Don't worry about the voluminous
console messages, unless one says &quot;FAIL&quot;.</p>
<p><font color="#FF0000"><i>You have to manually do this if you change
any of the data files in that version!</i></font></p>
<p>Note: if for any reason you modify the binary format of the BIN files, you also have to bump the
value in that file:</p>
<pre>static final byte BINARY_FORMAT = 8; // bumped if binary format of UCD changes</pre>
</li>
</ol>
</li>
<li>Results in <a href="file:///C:/DATA/GEN/DerivedData">
C:\DATA\GEN\DerivedData</a><ol>
<li>The files will be in this directory.</li>
<li>There are also DIFF folders, that contain BAT files that you can run
on Windows with CompareIt. (You can modify the code to build BATs with
another Diff program if you want).<ol>
<li>For any file with a significant difference, it will build two
BAT files, such as the first two below.<pre>Diff_PropList-5.0.0d10.txt.bat
OLDER-Diff_PropList-5.0.0d10.txt.bat
UNCHANGED-Diff_PropertyValueAliases-5.0.0d10.txt.bat</pre>
</li>
</ol>
</li>
<li>Any files without significant changes will have &quot;UNCHANGED&quot; as a
prefix: ignore them.&nbsp; The OLDER prefix is the comparison to the
last version of Unicode.</li>
<li>On Windows you can run these BATs to compare files:</li>
</ol>
</li>
<li><span style="background-color: #FFFF00">NFSkippable</span><ol>
<li><span style="background-color: #FFFF00">A file is needed by ICU that is
generated with the same tool. Just use the input parameter &quot;NFSkippable&quot; to
generate the file NFSafeSets.txt, also in </span>
<a href="file:///C:/DATA/GEN"><span style="background-color: #FFFF00">
file:///C:/DATA/GEN</span></a></li>
</ol>
</li>
</ol>
<h3>5. Invariant Checking</h3>
<ol>
<li>Setup<ol>
<li>Open in Package Explorer<ul>
<li>com.ibm.text.UCD<ul>
<li>TestUnicodeInvariants.java</li>
</ul>
</li>
</ul>
</li>
<li>Run&gt;Run As... Java Application<br>
Will create the following file of results:<pre><a href="file:///C:/DATA/GEN/UnicodeInvariantResults.txt/">C:\DATA\GEN\UnicodeInvariantResults.txt\</a></pre>
<p>And on the console will list whether any problems are found. Thus in
the following case there was one failure:</p>
<pre>ParseErrorCount=0
TestFailureCount=1</pre>
</li>
<li>The header of the result file explains the syntax of the tests.</li>
<li>Open that file and search for &quot;**** START Error Info ****&quot;. Each such
point provides a dump of comparison information.<ol>
<li>Failures print a list of differences between two sets being
compared. So if A and B are being compared, it prints all the items in
A-B, then in B-A, then in A&amp;B.</li>
<li>For example, here is a listing of a problem that must be corrected.
Note that usually there is a comment that explains what the following
line or lines are supposed to test. Then will come false (indicating
that the test failed), then the detailed error report.<pre><span style="font-size: 9pt"># Canonical decompositions (minus exclusions) must be identical across releases

<h3>6. Options</h3>
<ol>
<li>If you want to see files that are opened while processing, do the
following:<ol>

<li>Select the Arguments tab, and add the following<ol>
<li>VM arguments:
<pre>-DSHOW_FILES</pre>
</li>
</ol>

</ol>
</li>
</ol>
<h3>5. UCA</h3>
<ol>
<li>You will use com.ibm.text.UCA.Main as your main class, creating along
the same lines as above.</li>
<li>To test whether the UCA files are valid, use the
<span style="font-weight: 400">options (<i>note: you must also build the ICU
files below, since they test other aspects</i>).</span><pre>writeCollationValidityLog</pre>
<p>It will create a file:</p>
<pre><a href="file:///C:/DATA/GEN/collation/5.0.0/CheckCollationValidity.html">C:\DATA\GEN\collation\5.0.0\CheckCollationValidity.html</a></pre>
<ol>
<li>Review this file. It will list errors. Some of those are actually
warnings, and indicate possible problems (this is indicated in the text,
such as by: &quot;These are not necessarily errors, but should be examined for
<i>possible</i> errors&quot;). In those cases, the items should be reviewed to make
sure that there are no inadvertent problems.</li>
<li>If it is not so marked, it is a true error, and must be fixed.</li>
<li>At the end, there is section <b>11. Coverage</b>. There are two sections:<ol>
<li>In UCDxxx, but not in allkeys. Check this over to make sure that these
are all the characters that should get <b><i>implicit</i></b> weights.</li>
<li>In allkeys, but not in UCD. These should be <b><i>only</i></b>
contractions. Check them over to make sure they look right also.</li>
</ol></li>
</ol></li>
<li>
<h4><span style="font-weight: 400">To build all the charts (including for
the UCA), use the options: </span></h4>
<pre>normalizationChart caseChart scriptChart indexChart</pre>
<p>They will be built into</p>
<pre><a href="file:///C:/DATA/GEN/charts">C:\DATA\GEN\charts</a></pre>
<p><b>Once UCA is released, then copy those files up to the right spots in
the Unicode site:</b><ul>
<li>
<pre><a href="http://www.unicode.org/charts/normalization/">http://www.unicode.org/charts/normalization/</a></pre>
</li>
<li>
<pre><a href="http://www.unicode.org/charts/collation/">http://www.unicode.org/charts/collation/</a> </pre>

<h4><span style="font-weight: 400">To build all the UCA files used by ICU, use the
option:</span></h4>
<pre>ICU</pre>
<p>They will be built into:</p>
<pre><a href="file:///C:/DATA/GEN/collation/5.0.0">C:\DATA\GEN\collation\5.0.0</a></pre>
</li>
<li>You should then build a set of the ICU files for the previous version,
if you don't have them. Use the options:<pre>version 4.1.0 ICU</pre>
<p>Or whatever the last version was.</li>
<li>Now, you will want to compare versions. The key file is
UCA_Rules_NoCE.txt. It contains the rules expressed in ICU format, which
allows for comparison across versions of UCA without spurious variations of
the numbers getting in the way.<ol>
<li>Do a Diff between the last and current versions of these files, and
verify that all the differences are either new characters, or were
authorized to be changed by the UTC.</li>
