| 13 What is scrptrun and srtest?</h2> | |
| 14 The ICU LayoutEngine must be called with text in a single script. scrptrun.h | |
| 15 and scrptrun.cpp implement the ScriptRun class, which can be used to find | |
| 16 runs of text that is in a single script. 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> | |

| 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" | |

| 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> | |
