14 <h2> What are letest and gendata?</h2>
15 letest is a program you can use to verify that you have built and
16 installed the ICU LayoutEngine correctly. The test is not comprehensive,
17 it just verifies that the results of laying out some Devanagari, Arabic
18 and Thai text are as expected. Once this test has passed, you can use
19 the ICU LayoutEngine in your application knowing that it has been
20 correctly installed and that the basic functionality is in place.
21 <p>gendata is a program that is used by the ICU team to build the
22 source file testdata.cpp, which contains the expected results of running
23 letest. Unless you have changed your copy of the LayoutEngine and want
24 to validate the changes on other platforms, there's no reason for you
25 to run this program. </p>
26 <p>(The ICU team first runs a Windows application which uses the ICU
27 LayoutEngine to display the text that letest uses. Once it has been
28 verified that the text is displayed correctly, gendata is run to produce
29 testdata.cpp, and then letest is run on Windows to verify that letest
30 still works with the new data.) <br>
32 <h2> How do I build letest?</h2>
33 First, you need to build ICU, including the LayoutEngine.
34 <p>On Windows, the layout project should be listed as a dependency of
35 all, so layout will build when you build all. If it doesn't for some
36 reason, just select the layout project in the project toolbar and build
38 <p>On UNIX systems, you need to add the "--enable-layout=yes" option
39 when you invoke the runConfigureICU script. When you've done that,
40 layout should build when you do "make all install" </p>
41 <p>To build letest on Windows, just open the letest project in
42 <icu>\source\test\letest and build it. On UNIX systems, connect to
43 <top-build-dir>/test/letest and do "make all" <br>
45 <h2> How do I run letest?</h2>
46 Before you can run letest, you'll need to get the fonts it uses. For
47 legal reasons, we can't include them with ICU, but you can download them
48 from the web. To do this, you'll need access to a computer running
49 Windows. Here's how to get the fonts:
50 <p>Download the 1.3 version of the JDK from the<a
51 href="http://www.ibm.com/java"> IBM developerWorks Java technology zone</a>
52 page. From this page, follow the "Tools and products" link on the left
53 hand side, and then the link for the "IBM Developer Kit for Linux", or
54 the "IBM Developer Kit for Windows(R), Release 1.3.0". You'll need to
55 register with them if you haven't downloaded before. Download and
56 install the "Runtime Environment Package." You'll need two fonts from
57 this package. If you've let the installer use it's defaults, the fonts
58 will be in C:\Program Files\IBM\Java13\jre\lib\fonts. The files you want
59 are "LucidaSansRegular.ttf" and "Thonburi.ttf" Copy these font files to
60 the directory from which you'll run letest.<br>
62 <p>Next is the Hindi font. Go to the NCST site and download <a
63 href="http://rohini.ncst.ernet.in/indix/download/font/raghu.ttf">
64 raghu.ttf</a>. Be sure to look at the <a
65 href="http://rohini.ncst.ernet.in/indix/download/font/README"> README</a>
66 file before you download the font. You can download raghu.ttf into the
67 directory from which you'll run letest.<br>
69 <p>There's still one more font to get, the Code2000 Unicode font.Go to
70 James Kass' <a href="http://home.att.net/%7Ejameskass/">Unicode
71 Support In Your Browser</a> page and click on the link that says "Click
72 Here to download Code2000 shareware demo Unicode font." This will
73 download a .ZIP file which contains CODE2000.TTF and CODE2000.HTM.
74 Expand this .ZIP file and put the CODE2000.TTF file in the directory
75 from which you'll run letest.<br>
77 <p><span style="font-weight: bold;">Note:</span> The Code2000 font is
78 shareware. If you want to use it for longer than a trial period, you
79 should send a shareware fee to James. Directions for how to do this are
81 <p>That's it! Now all you have to do is run letest (CTRL+F5 in Visual
82 C++, or "./letest" in UNIX) If everything's OK you should see
83 something like this: </p>
84 <blockquote><tt>Test 0, font = raghu.ttf... passed.</tt> <br>
85 <tt>Test 1, font = CODE2000.TTF... passed.</tt> <br>
86 <tt>Test 2, font = LucidaSansRegular.ttf... passed.</tt> <br>
87 <tt>Test 3, font = Thonburi.ttf... passed.</tt></blockquote>
