How to check for {CMDSEGMENT:segment} NOT SET in a conditional block

[Dee]

Hi,

I'm new to VoiceAttack, using it for basic control of my computer in order to reduce RSI. So far it's already making a huge difference with just a couple dozen commands. Many thanks to the developer Gary for this brilliant app!

I'm hoping someone can help with the following.

I am creating a command that will navigate from word to word in text by pressing Ctrl+Right/Left [num] times.

Here's my voice command:

Code: [Select]

word [right; left] [; 2; 3]
Here are the commands:

Code: [Select]

Write '[Blue] CMDSEGMENT has been set to: {TXT:'{CMDSEGMENT:2}'}' to log
Begin Text Compare : [{CMDSEGMENT:2}] Has Not Been Set
    Write '[Blue] Not set!' to log
    Set small int (condition) [num] value to 1
Else
    Write '[Blue] Set!' to log
    Set small int (condition) [num] value to the converted value of {CMDSEGMENT:2}
End Condition
Write '[Blue] num = {SMALL:num}' to log
Here's the result.

If I say "word right", the log says:

Code: [Select]

Recognized : 'word right'
CMDSEGMENT has been set to: Not set
Set!
Small integer token could not be converted : {CMDSEGMENT:2}
num = Not set
If I say "word right 2", the log says:

Code: [Select]

Recognized : 'word right 2'
CMDSEGMENT has been set to: Not set
Set!
num = 2
Thanks

Tokens are not variables, so that comparator cannot work; Tokens also always return text(so technically the result is never NULL, which would be the internal value that VoiceAttack renders as "Not Set").

You have to compare literal text instead:

Code: [Select]

Begin Condition : [{CMDSEGMENT:2}] Equals '' OR [{CMDSEGMENT:2}] Equals 'Not Set'
End Condition

{CMDSEGMENT:} will return ""(blank) if a segment is not spoken, or "Not Set" if the index points to a nonexistent segment, which can happen if multiple phrase options are used for a command.

E.G. "this is one [option;] with three segments;This one only has one segment", Using "{CMDSEGMENT:1}" with the former would either return ""(blank) or "option", using it with the latter instead would always result in "Not Set", because there is no second segment.

Hi Pfeil,

Thank you very much for that helpful explanation.

Now I'm getting a different error:

Code: [Select]

Begin Text Compare : [{CMDSEGMENT:2}] Equals ''
    Set small int (condition) [num] value to 1
Else
    Set small int (condition) [num] value to the converted value of {CMDSEGMENT:2}
End Condition
Write '[Blue] num = {SMALL:num}' to log
Begin Text Compare : [{CMDSEGMENT:1}] Equals 'right'
    Start Loop : Repeat [num] Times
        Press Left Ctrl+Right keys and hold for 0.01 seconds and release
    End Loop
End Condition
Here's the log:

Code: [Select]

Recognized : 'word right'
num = 1
Unable to resolve for loop context: num.  Exiting command.
Am I referencing the variable incorrectly?

[Pfeil]

For loops take an integer value, not a small.

As a general rule, you should probably always use integer; Gary intends to deprecate small, which offers no real advantages over int in the context of VoiceAttack.

Thank you, that did the trick
