One final requirement before the Tcl dialogue is complete is to create the `tclIndex' file.
Tcl uses a method whereby Tcl files are only loaded and executed when a command is first needed. This is done by referencing auto_index array in the Tcl error handler. This handler requires the `tclIndex' files to determine the location of each command. Failing to create this file will cause Tcl to complain that a command does not exist.
To create a `tclIndex' file start up either
and type '
auto_mkindex dir' where dir is the name of the
directory (often simply ".") containing the Tcl files. For the composition
package this created the following `tclIndex' file.
# Tcl autoload index file, version 2.0 # This file is generated by the "auto_mkindex" command # and sourced to set up indexing information for one or # more commands. Typically each line is a command that # sets an element in the auto_index array, where the # element name is the name of a command and the value is # a script that loads the command. set auto_index(Composition) [list source [file join $dir composition.tcl]] set auto_index(Composition2) [list source [file join $dir composition.tcl]]
