Accessing a [namespace current] variable

2022-03-23T13:22:26-04:00

Thanks guys.

I'll probably use the last method from SpiKe^^ as I'll have to use [namespace parent] sometimes.

Using upvar is a way I'd looked, but it's less flexible imho

The common method using [variable] similar to [global]....

Code:

    proc readit {} {   ;# common method        variable v       putlog "v is now $v"     }

Another method I find handy....

Code:

    proc readit {} {        # another method       putlog "v is now [set [namespace current]::v]"     }

Accessing a [namespace current] variable

Code:

namespace eval myns {variable vproc doit {} {incr [namespace current]::v}proc readit {} {variable vputlog "v is now $v"   }}

Or you can use upvar:

Code:

namespace eval myns {variable vproc doit {} {incr [namespace current]::v 1}proc readit {} {upvar 1 [namespace current]::v vputlog "v is now $v"   }}

Btw, there's no need for the '1' in the incr line as by default it increments with one.

Accessing a [namespace current] variable

Hi there,

I've a little trouble with a script I'm writing. I'm trying to do it really modular with the minimum of hardcoded things.

The code looks like (just an example):

Code:

namespace eval myns {   variable v    proc doit {} {      # This works      incr [namespace current]::v 1   }   proc readit {} {      # this fails      putlog "v is now $[namespace current]::v"   }}

The proc readit doesn't work, I can't figure out how to access $::myns::v using [namespace current]. All ideas are welcome
