[2.14] #ADDITEM/#ADDKEY and #IF with local var
|
For some reason when a local variable has its contents set by #ADDITEM it fails this non null test
| Code: |
$Used=""
#ADDITEM $Used {some}
#IF ($Used) {
#SHOW Passed if $Used
} {
#SHOW Failed if $Used
} |
It continues to fail with multiple #ADDITEMs. Setting a value other then "" initially works unless the variable gets set to null along the way. An expression of $var!="" does work, so it is just the non expression.
This also fails
| Code: |
| $USED="";#ADDKEY $USED {test} {Tesy};#IF ($USED) {#SHOW yes} {#SHOW Failed $USED} |

We can also add #RESULT to the commands that get a null value returned after #ADDITEM.
| Code: |
<func name="DirConvert" type="StringList" id="16">
<value>#IF ($dir="") {
#SHOW Error in DirConvert: null direction passed
#RETURN ""
}
$Res=""
#FORALL $dir {
#ADDITEM $Res {%reversedir(%reversedir(%exec(%concat(%pref(iMoveChar),%i))),1)}
}
#SAY $Res
#RESULT $Res</value>
<arglist>$dir</arglist>
</func> |
Drop that function in then enter at the command line
| Code: |
| #SHOW @DirConvert("h|j|k|l") |
You will see the #SAY can get the value, but #RESULT can not. That makes this not a problem in #IF. |

Added to bug list as two separate bugs since I'm not sure they are caused by the same problem yet.
