Tcl/Tk in a Nutshell

Name

interp

interp option [arg...]

Manage Tcl interpreters. A master Tcl interpreter can create a new interpreter, called a slave, which coexists with the master. Each interpreter has its own namespace for commands, procedures, and global variables. Using aliases, a command in a slave interpreter can cause a command to be invoked in the master or another slave interpreter. Safe interpreters can be created that may be used for executing untrusted code because all potentially dangerous commands have been disabled by making them hidden.

interp alias srcPath srcCmd

Return a list containing the target command and arguments for the alias named srcCmd in interpreter specified by srcPath.

interp alias srcPath srcCmd {}

Delete the alias named srcCmd from the interpreter specified by srcPath.

interp alias srcPath srcCmd targetPath targetCmd [arg...]

Create an alias between two slave Tcl interpreters. The source command is named srcCmd in interpreter srcPath and is placed in interpreter target-Path as command targetCmd. Additional arguments to be appended to targetCmd can be specified.

interp aliases [path]

Return a list of the command aliases defined in interpreter path.

interp create [-safe] [- -] [path]

Create a slave interpreter using the specified path.
