The following is a list of AIX XIM module features: • AIX XIM module has the first loading priority. • AIX XIM module tries to query specified language and IM modifier (XMODIFIERS) to the AIX Input Method. 8.2.21.2 AIX XIM Interface for Input Method Switching X Consortium's sample code implements an input method switching mechanism at the top of XIM layer. All X input methods are registered at _XimImSportRec in the imImSw.c file. The _XimOpenIM() function invokes the checkprocessing method of the registered X input method to check that the X input method is supported by the specified locale and IM modifier. If the input method is supported, then the _XimOpenIM() function calls im_open method of the XIM. If it fails to open IM, then the im_free method is called to close it down. The following section describes the methods provided by AIX's XIM module: (*checkprocessing)() - _XimCheckIfAIXProcessing This routine is called from the _XimOpenIM() function to check that a XIM module supports specified IM information (locale and modifiers). This function returns True with the following conditions: • If the XMODIFIERS is not specified, and the specified locale is supported by the AIX Input Method. • If the specified XMODIFIERS and locale combination are supported by the AIX Input Method. If the XMODIFIERS is specified, a combined AIX IM name is used to check if the specified locale and modifier combination are supported by the AIX IM. To make a combined AIX name, concatenate the IM modifier to the locale name. The AIX IM function accepts a language name that contains the IM modifier @im=. For example: $LANG = xx_XX $XMODIFIERS = @im=foo Combined Name = xx_XX@im=foo AIX IM module = xx_XX@foo (*im_open)() - _XimAIXOpenIM This routine is called from the _XimOpenIM() function when an application calls XOpenIM(). (*im_free)() - _XimAIXIMFree This routine is called from the im_free() function and is used to close down the input method. 8.2.22 Input Method Protocol Some languages need complex pre-editing input methods. Such an input method may be implemented separately from applications in a process called an Input Method (IM) Server. The IM Server handles the display of pre-edit text and the user's input operation. The Input Method (IM) Protocol standardizes the 206 AIX Version 4.3 Differences Guide
communication between the IM Server and the IM library linked with the application. The IM Protocol is a completely new protocol based on experience with R5’s sample implementations. The following new features are added beyond the mechanisms in the R5 sample implementations: • The IM Server can support any of several transports for connection with the IM library. • Both the IM Server and clients can authenticate each other for security. • A client can connect to an IM Server without restarting, even if it starts up before the IM Server. • A client can initiate string conversion to the IM Server for reconversion of text. • A client can specify some keys as hot keys, which can be used to escape from the normal input method processing regardless of the input method state. The R6 sample implementation for the internationalization support in Xlib has a new plugin framework with the capability of loading and switching locale object modules dynamically. For backward compatibility, the R6 sample implementation can support the R5 protocols by switching to IM modules supporting those protocols. In addition, the framework provides the following new functions and mechanisms: X Locale database format An X locale database format is defined, and the subset of a user's environment dependent on language is provided as a plain ASCII text file. You can customize the behavior of Xlib without changing Xlib itself. ANSI C and non-ANSI C bindings The common set of methods and structures are defined that bind the X locale to the system locales within libc, and a framework for implementing this common set under non-ANSI C base system is provided. Converters The sample implementation has a mechanism to support various encodings by plugin converters and provides the following converters: • Light-weight converter for C and ISO 8859 • Generic converter • High-performance converter for Shift-JIS and EUC • Converter for UCS-2 defined in ISO/IEC 10646-1 Locale modules The library is implemented so that input methods and output methods are separated and are independent of each other. Therefore, an output-only client does not link with the IM code, and an input-only client does not link with the OM code. Locale modules can be loaded on demand if the platform supports dynamic loading. Transport Layer There are several kinds of transports for connection between the IM library and the IM Server. The IM Protocol is independent of a specific transport layer protocol, and the sample implementation has a Graphical Environment Enhancements 207
