namespace inscope executes a script in the context of
namespace.
Synopsis edit
namespace inscope namespace script ?arg ...? Description edit
Each
arg is quoted so that no further substitutions are performed on it, and is appened as an additional word of the final command in
script, and then
script is passed to the interpreter for evalation in
namespace.
namespace inscope ::foo $script $x $y $z is equivalent to
namespace eval ::foo [concat $script [list $x $y $z]].
In contrast with
namespace eval,
namespace must already exist.
namespace inscope is not expected to be used directly by programmers. Rather,
namespace code generates a
namespace inscope command that, when evaluated, executes
script in the context of
namespace. The result of
namespace code is often passed to Tk commands that arrange for scripts to be evaluated in response to events.
Like
namespace eval,
namespace inscope adds a
level to the interpreter.
apply and
tailcall, provide a way to do what
namespace inscope does, but without adding a level.
