Name

dtimsstart -- launches an input method server

Synopsis

dtimsstart [-env] [-ims name] [-shell name] [-host hostname] [-imsopt options] [-list]

Description

The dtimsstart command launches an IMS (Input Method Server). dtimsstart is normally invoked automatically at Xsession startup (user login) by the script /usr/dt/config/Xsession.d/0020.dtims.

Depending on the currently selected locale, environment variables, configuration files, and command-line options, dtimsstart displays a selection window from which you can select the IMS you want to use. Once you select the IMS, dtimsstart starts it and waits until the IMS completes its startup. This is to ensure that applications wishing to connect to the IMS can do so. dtimsstart then sets the XMODIFIERS environment variable to ensure that clients can connect to the selected IMS. Finally, dtimsstart exits.

Once you select an IMS from the selection window, dtimsstart saves the selection in the IMS Selection File. To have dtimsstart automatically start the previously selected IMS, set the IMS Selection Mode to resume-current-input-method. You access the IMS Selection Mode by executing the DtImsMode action located in Desktop_Tools in the Application Manager.

For IMS Selection Mode, you can choose:

ask-at-login
Instructs dtimsstart to display the selection window and prompt you for an IMS each time it is invoked.
resume-current-input-method
Instructs dtimsstart to automatically start the last selected IMS by using the saved IMS Selection File and without displaying the selection window.

Remote Execution of IMS

If you use the -host option to have dtimsstart start an IMS on a remote host, dtimsstart does the following:

Executes the DtImsGetRemoteConf action to retrieve IMS configuration data from the specified remote system
Lists the IMSs registered on the remote system in the selection window
Executes the DtImsRunRemoteIms action to start the selected IMS on the remote system.

For more information on configuring remote execution, refer to the Common Desktop Environment: Advanced User’s and System Administrator’s Guide.

Options

The following options are available:

-env
Outputs the contents of the XMODIFIERS environment variable to stdout. dtimsstart automatically updates this variable to reflect the currently selected IMS. Use this option to verify that the intended IMS is the one that is being started. If you omit this option, no output occurs.
-ims name
The name of the IMS to be started. If you specify this option, dtimsstart starts the IMS without displaying the selection window. If you omit this option, dtimsstart displays the selection window.
-shell name
The output format to use, of output, if -env is specified. If you omit this option, dtimsstart uses the value of $SHELL as the default.
-host hostname
The name of the host on which the IMS is to run. If you omit this option, dtimsstart uses the local host as the default.
-imsopt options
The command line options for the selected IMS.
-list
Instructs dtimsstart to output the names of input methods registered on the system and then exit immediately.

Exit Status

0
The IMS was started successfully.
1
Execution failed for one of the following reasons:
The started IMS did not complete its initialization within the timeout period.
The started IMS process aborted.
The IMS specified by the -ims option is not registered.
2
A syntax error was found.

Environment Variables

dtimsstart references the following environment variables:

HOME
The home directory.
LANG
The locale.
DISPLAY
The type of display on which IMS is to be run.

It sets the XMODIFIERS variable to the name of the selected IMS to support application and client connections.

Resource Files

dtimsstart searches a proper resource file in the following order and loads the first file successfully opened.

1.
$HOME/.dt/<display-name>/current/dt.resources
2.
$HOME/.dt/<display-name>/home/dt.resources
3.
$HOME/.dt/sessions/current/dt.resources

Configuration Files

dtimsstart refers to the following configuration files:

Locale Entry file
IMS configuration file
IMS Selection file

The location and format for each configuration file is listed below.

Locale Entry File

This file lists the IMSs that support the locale. Its location is /usr/dt/config/ims/<locale_name>. The format is:

@Default: ims_name

ims_name: label_string

For example: 


CW/usr/dt/config/ims/ja_JP.SJIS
@Default:  xjim
xjim:      HP XJIM
atok8:     ATOK8
vje:       VJE-gamma
egbridge:  EGBridge
none:      No Input Method

IMS Entry File

This file describes the attributes of an IMS. Its location is /usr/dt/config/ims/<ims_name>. The format is:

attribute_name: attribute_value

The IMS attributes are:

protocols
A required String that lists the supported protocols. The supported XIM protocols are XIM, Ximp, and Xsi.
server_name
A required String that identifies the IMS name (used to update the XMODIFIERS environment variable).
cmd_path
A required Path type that specifies the absolute path of the executable file for the identified IMS server. A built-in keyword is used for the local IM built-in Xlib, which does not need a separate process.
cmd_param
A String that specifies the command line option(s) for the IMS server.
env_set
A String that identifies the environment variables to be set, excluding XMODIFIERS.
env_unset
A String that identifies environment variables to be unset, excluding XMODIFIERS.
env_pass
A String that identifies the environment variables to be passed to a remotely executing IMS, excluding LANG, DISPLAY, and XMODIFIERS.
has_window
A Bool indicating whether the IMS has its own main window appearance or not. The default is False.
no_server
A Bool indicating whether dtimsstart should start the IMS or not. It should be True for the local IM, since it doesn’t require any server process started by dtimsstart. The default is False.
no_remote
A Bool indicating whether the IMS allows remote execution or not. The default is False.
no_option
A Bool indicating whether the IMS allows the command-line option or not. If True, any options specfied by -imsopt are ignored, though the value of the cmd_param entry is always applied regardless of this value. It should be True for the local IMS. The default is False.

Note:

For entries that accept multiple values, the values are separated by white space(s). If multiple entries of the same name appear in the file, only the last entry is used.

For example: 


CW/usr/dt/config/ims/xjim
protocols:    XIM Ximp
server_name:  xjim
cmd_path:     /usr/bin/X11/xjim
cmd_param:    -iconic
env_set:
env_unset:
env_pass:
has_window:   true

IMS Selection File

This file saves the most recently selected IMS for each locale. Its location is $HOME/.dt/ims/[<display_name>/]<locale_name>. The format is:

entry_name: entry_value

The selection file entries are:

@SelectMode
The most recently set IMS Selection Mode. Valid values are 0 (zero) (for ask-at-login) and 1 (for resume-current-input-method ).
@ImsName
The name of the most recently selected IMS.
@HostName
The name of the host on which the IMS runs.

For example: 


CW$HOME/.dt/ims/ja_JP.SJIS
@SelectMode:  1
@ImsName:     atok8
@HostName:    host-A

Example

The command to execute dtimsstart in the /usr/dt/config/Xsession.d/0020.dtims script is as follows: 


CWeval  ‘ /usr/dt/bin/dtimsstart  -env -shell ksh ‘
