[Duoas] Hey there. Recent versions of tcl seem to like the wonky X.Y'''aZ''' version numbers, which 'package vcompare' can't quite comprehend --> resulting in a crashed tclkit whenever an attempt to source it is made. I've "repaired" my sdx.kit by changing the "sdx.vfs/main.tcl" file to read:

 package require starkit
 
 # old tclkits have broken "sourced" symlink detection (in their "starkit" pkg)
 # let SDX work in older ones but don't allow sourcing, which is a new feature
 if {[starkit::startup] eq "sourced" &&
     [package vcompare [lindex 0 [regsub \[a-z\] [info patchlevel] { }]] 8.4.9] >= 0} return
 
 package require app-sdx

The thing I am not sure about is whether I am handling the version number correctly. Should it instead read:

     [package vcompare [regsub \[a-z\] [info patchlevel] .] 8.4.9] >= 0} return

In other words, does 8.5a4 == 8.5.4?

''[Lars H]: No, "a" is more like ".-2.", i.e., 8.5a4 < 8.5.0. See [TIP]#268 [http://tip.tcl.tk/268].''

[Duoas] OK, I understand now. I amend my code to the simpler:

     [package vcompare [lindex 0 [split [info patchlevel] ab]] 8.4.9 >= 0} return

Which for this ''particular'' comparison is sufficient.

Either way, this needs to be addressed in the sdx.kit distribution.
