TclXInit(TCL) TclXInit(TCL) NAME Tclx_Init, Tclxcmd_Init, TclX_Main, Tkx_Init, TkX_Main - Extended Tcl initialization. SYNOPSIS -ltclx -ltcl #include "tclExtend.h" int Tclx_Init (Tcl_Interp *interp); int Tclxcmd_Init (Tcl_Interp *interp); int void TclX_Main (int argc, char **argv, Tcl_AppInitProc *appInitProc); int Tkx_Init (Tcl_Interp *interp); void TkX_Main (int argc, char **argv, Tcl_AppInitProc *appInitProc); void TclX_SetAppInfo (int defaultValues, char *appName, char *appLongName, char *appVersion, int appPatchlevel); DESCRIPTION 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 inter- preter. 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 spec- ification (Unix shell compatible). It creates an interpreter and calls the specified function appInitProc to initialize any application spe- cific commands. It then either evaluates the command of script speci- fied 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_Ap- pInit 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 spec- ification. 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. DYNAMIC LOADING OF TCLX 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 pkgIn- dex,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 exist- ing 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. INTEGRATING TCLX WITH OTHER EXTENSIONS AND APPLICATIONS The main aspects to integrating TclX with into an application is to de- cide 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 nec- essary 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 func- tionality, call TkX_Main from the main function instead of Tk_Main. This shell has SIGINT signal handling when interactive, Tcl TclXInit(TCL)
