NAME


interp - Interp creation and aliasing






SYNOPSIS


package require Tcl 8.5 9


package require interp ?0.1.3?


::interp::createEmpty ?path?


::interp::snitLink path methodlist


::interp::snitDictLink path methoddict










DESCRIPTION


This package provides a number of commands for the convenient
    creation of Tcl interpreters for highly restricted execution.






API



  
::interp::createEmpty ?path?

  
This commands creates an empty Tcl interpreter and returns it name. Empty
      means that the new interpreter has neither namespaces, nor any commands.
      It is useful only for the creation of aliases.
    
If a path is specified then it is taken as the name of
        the new interpreter.

  

  
::interp::snitLink path methodlist

  
This command assumes that it was called from within a method of a snit
      object, and that the command mymethod is available.
    
It extends the interpreter specified by path with
        aliases for all methods found in the methodlist, with the alias
        directing execution to the same-named method of the snit object invoking
        this command. Each element of methodlist is actually interpreted
        as a command prefix, with the first word of each prefix the name of the
        method to link to.

    
The result of the command is the empty string.

  

  
::interp::snitDictLink path methoddict

  
This command behaves like ::interp::snitLink, except that it takes
      a dictionary mapping from commands to methods as its input, and not a list
      of methods. Like for ::interp::snitLink the method references are
      actually command prefixes. This command allows the creation of more
      complex command-method mappings than ::interp::snitLink.
    
The result of the command is the empty string.
