These functions are used to initialize Extended Tcl and applications based on Extended Tcl. This manual page also discusses various issues and approaches of integrating TclX into other applications.
Tclx_Init
Initializes Extended Tcl, adding the extended command set to
the interpreter. This is called from Tcl_AppInit.
This function must be called after the Tcl_Init
function. In addition to the standard command set, it
enables use of tlib packages libraries and makes the
standard TclX library available.
Parameters
o interp - A pointer to the interpreter to add the commands to.
Returns:
TCL_OK if all is ok, TCL_ERROR if an error occurred.
Tclxcmd_Init
Add the TclX command set to the interpreter, with the
exception of the TclX library management commands. This is
normally called by Tclx_Init and should only be used
if you don’t want the TclX library handling.
Parameters
o interp - A pointer to the interpreter to add the commands to.
Returns:
TCL_OK if all is ok, TCL_ERROR if an error occurred.
TclX_Main
This function parses the command line according to the TclX
shell specification (Unix shell compatible). It creates an
interpreter and calls the specified function
appInitProc to initialize any application specific
commands. It then either evaluates the command of script
specified on the command line or enters an interactive
command loop. This procedure never returns, it exits the
process when it’s done. Using the TclX shell also
gives you SIGINT handling in interactive shells.
Tkx_Init
Initializes Extended Tcl Tk environment. This is called from
Tcl_AppInit after the Tk_Init function.
Parameters
o interp - A pointer to the interpreter to add the commands to.
Returns:
TCL_OK if all is ok, TCL_ERROR if an error occurred.
TkX_Main
This function parses the command line according to the wish
shell specification. It creates an interpreter and calls the
specified function appInitProc to initialize any
application specific commands. It then either evaluates the
command of script specified on the command line or enters an
interactive command loop. This procedure never returns, it
exits the process when it’s done. Using the TclX wish
shell gives you SIGINT handling in interactive shells,
otherwise it is identical to standard wish.
TclX_SetAppInfo
Store the application information returned by infox.
Parameters
o defaultValues -
If true, then the values are assigned only if they are not
already defined (defaulted). If false, the values are always
set.
o appName - Application symbolic name.
o appLongName - Long, natural language
application name.
o appVersion - Version number of the application.
o appPatchlevel - Patch level of the application.
If less than zero, don’t change.
String pointers are saved without copying, don’t release the memory. If the arguments are NULL, don’t change the values.
TclX can be dynamically loaded on systems that support shared libraries and the load command. This can be done using either the load or the package require commands. If package require is to be used, a pkgIndex,tcl must be constructed. The pkg_mkIndex does not generate a pkgIndex.tcl file that works with TclX. Instead a command similar to
package ifneeded Tclx 7.5.0 "load $dir/libtclx.so"
should be placed in the directory containing the TclX shared library. A prototype pkgIndex,tcl file is build by TclX and is installed in the run time directory under the name pkgIndex,proto. This file can’t be used as-is, but should be renamed and copied or combined with an existing pkgIndex,tcl in the directory containing the shared library.
There is no need to dynamically load libtkx.so, since it only contains support for wishx.
The main
aspects to integrating TclX with into an application is to
decide if the application is based on the standard Tcl/Tk
shells or the TclX shells. If the standard shells are
desired, then all that is necessary is to call
Tclx_Init after Tcl_Init and
Tkx_Init after Tk_Init. This functionality may
also be dynamically loaded.
To get the TclX shell in a Tcl only application, with the tcl command functionality, call TclX_Main from the main function instead of Tcl_Main. This shell has arguments conforming to other Unix shells and SIGINT signal handling when interactive,.
To get the Tclx shell in a Tk application, with the wishx command functionality, call TkX_Main from the main function instead of Tk_Main. This shell has SIGINT signal handling when interactive,
