Re: [TCLCORE] Migration tool for Tcl 9

[Paul O. <pa...@po...>]

For the following simple test script:
namespace eval poImg {
     variable DrawPos

     set DrawPos(x) 0
     set DrawPos(y) 0
}

I get the following warnings from tcl9-migrate:
Line   4: W Variable "DrawPos(x)" possibly set without a variable or global declaration within namespace ::poImg. [UNDECLARED]
Line   5: W Variable "DrawPos(y)" possibly set without a variable or global declaration within namespace ::poImg. [UNDECLARED]

Is this a false negative?

It includes a static checker based on Nagelfar as well as a runtime shim that fixes up incompatibilities like i/o encoding errors, tilde expansion, package requirements etc., allowing the scripts to be loaded while emitting warnings.
