im-switch
IM-SWITCH(8) System Manager's Manual IM-SWITCH(8) NAME
im-switch - set up input method for X Window SYNOPSIS
im-switch [-v][-z ll_CC] -s inputmethodname im-switch [-v][-z ll_CC] -c im-switch [-v][-z ll_CC] -a im-switch [-v][-z ll_CC] -l im-switch -h im-switch DESCRIPTION
This manual page very briefly documents the im-switch command. The im-switch command provides the framework to configure and to switch the input method on X Window System depending on the locale. This input method is the essential mechanism for Japanese, Chinese and Korean (CJK) languages to enter their non-ASCII native characters. Some input methods such as IBus, SCIM, and uim support not only one of these CJK languages but support almost all languages simultaneously by dynamically switching keyboard modes with GUI. The most desirable input method is provided as the configurable system wide default using Debian alternatives mechanism with /etc/alterna- tives/xinput-ll_CC link. The X start up code sources /etc/X11/Xsession.d/90im-switch which read the configuration file and activates the input method. The user configuration files and links are located in ~/.xinput.d/ . The system configuration files and links are located in /etc/X11/xinit/xin- put.d/ . This structure ensures to have different input methods to be installed side-by-side. im-switch understands the following options: -v Display verbose message during execution. -z ll_CC Set up the input method for X run under ll_CC locale (ISO 639 / ISO 3188). When changing the fallback default for all locales, use all_ALL as the quasi-locale value here. The setup by this all_ALL does not override specific setups. -s inputmethodname Set up the input method to use inputmethodname. -c Configure the input method with menu. (Under X, this uses GUI.) -a Reset the input method to the system default. -l List the input method configuration. -h Print a help message to the standard output and exit. When the im-switch command is invoked without any command arguments, it functions as -c option case. This is meant to be used by the GUI menu. SEE ALSO
