opening-trainer

I had some issues with the Opening-trainer.
I'am using scid-4.7.0-r1 in Linux-gentoo

I was able to resolve the issues by applying the following patch

--- opening.old.tcl 2023-09-06 19:37:03.657183737 +0200
+++ opening.tcl 2023-09-06 19:38:55.541989107 +0200

set nlist [lindex $cm [expr $x+1] ]

•  if {$displayCMValue} {
  

•  if {info exists $displayCMValue} {
     foreach n $nlist {
       append tmp $n " "
     }
  

The issues I experienced have probably something to do with; that in the Openings-trainer I use backward going through the game to see if there are alternatives for the move I played when training.

The patch seems to resolve this; looking at the tcl-code "info exists" is probably what was meant; could be a change in tcl.

I hope this info is usefull.

The patch I gave above is not correct.
It should be
