It uses a basic iteration interface. 17 <p>srtest is a little program that tests ScriptRun. You can use it as an 18 example of how to use ScriptRun. Here's what the output should look like: 19 <blockquote><font face="Courier New,Courier"><font size=-1>Script 'DEVANAGARI' 20 from 0 to 9.</font></font> 21 <br><font face="Courier New,Courier"><font size=-1>Script 'ARABIC' from 22 9 to 17.</font></font> 23 <br><font face="Courier New,Courier"><font size=-1>Script 'CYRILLIC' from 24 17 to 25.</font></font> 25 <br><font face="Courier New,Courier"><font size=-1>Script 'LATIN' from 26 25 to 33.</font></font> 27 <br><font face="Courier New,Courier"><font size=-1>Script 'HAN' from 33 28 to 35.</font></font> 29 <br><font face="Courier New,Courier"><font size=-1>Script 'HIRAGANA' from 30 35 to 41.</font></font> 31 <br><font face="Courier New,Courier"><font size=-1>Script 'KATAKANA' from 32 41 to 45.</font></font> 33 <br><font face="Courier New,Courier"><font size=-1>Script 'DESERET' from 34 45 to 53.</font></font></blockquote> 35 36 <h2> 37 How do I build scrptrun and srtest?</h2> 38 To use the ScriptRun class in a Windows application, just include scrptrun.h 39 and scrptrun.cpp right out of the <icu>\source\extra\scrptrun directory 40 into your project. You'll also need to add the <icu>\source]extra\scrptrun 41 directory to the "Additional include directories" section of the "Preprocessor" 42 category on the "C/C++" tab in the project settings. 43 <p>On UNIX systems the simplest thing to do is to just copy scrptrun.h 44 and scrptrun.cpp into your source directory. If you want to use them from 45 <icu>/source/extra/scrpturn, it's a bit trickier: the default dependency 46 rules don't work on source files in a different directory. You need to 47 add separate dependency rules for scrptrun.o and scrptrun.d. See <icu>/source/samples/layout/Makefile.in 48 for an example of how to do this. You'll also have to add -I$(top_srcdir)/extra/scrptrun 49 to your compiler flags so that the compiler can find scrptrun.h. If your 50 application has to build on multiple UNIX platforms, it might be difficult 51 to wirte dependency rules that will work correctly on all platforms. In 52 that case, you're probably better off copying the scrpturn files to your 53 source directory. 54 <p>Building srtest is easy, on Windows build the srtest workspace in <icu>\source\extra\scrptrun. 55 On UNIX, connect to <top-build-dir>/extra/scrptrun and do "make all" 56 <h2> 57 Notes</h2> 58 59 <ul> 60 <li> 61 ScriptRun is based on <a href="http://www.unicode.org/unicode/reports/tr24/">Unicode 62 Technical Report #24</a> but the implementation is not complete. In particular 63 the support for paired punctuation is only a prototype. A complete implementation 64 will be added to ICU in the future.</li> 65 </ul> 66 67 </body> 68 </html> 69
