Working with strings/text

[claude.rivet]

I searched the help and forums and I could not find the answer, I was wondering how to work with text for a simple task.

I have a bunch of variables of the same type used for various identical modules used concurrently, it looks like this:

me1folder
me2folder
me3folder

Now my goal would be to get the user to just write the number in the function argument and my script would reconstruct the variable name by just changing the number in it. So if the user writes the function as

Code: Select all

mixit{2}

inside the function I would write something like

Code: Select all

VValue,me & arg1 & folder,99

It probably is not the good procedure but I hope you guys get the idea, is it possible?

Thanks for the help

I think only with a text combiner node is this possible... but maybe there is another way.

Hey,

You can create a function for that. Call it something like "concat{str1,str2}" and use the following code:

Code: Select all

VString,_tmp_concat,
VValue,_tmp_concat,str1
VAdd,_tmp_concat,_tmp_concat,str2
Return _tmp_concat

This will return the two strings glued together, for example calling "concat{dennis,kuypers}" will give you "denniskuypers"

If you only need it for your "ID" insertion then you can have a slightly different version like so: "mixit{number}"

Code: Select all

VString,_tmp_mixit,me
VAdd,_tmp_mixit,_tmp_mixit,number
VAdd,_tmp_mixit,_tmp_mixit,folder
Return _tmp_mixit

This will create your "meNUMBERfolder" string, a call to "mixit{4}" gives you "me4folder"

I haven't tested it but it should work like that.

Best regards
Dennis

Great, I'll try those methods, it makes sense, I like the function method but I guess I was mainly looking at the correct commands to use to merge strings, I thought VAdd was requiring number variables, happy to know it works for strings.

Thanks, much appreciated!

Cool! I did not know that either. Vadd for combining text is very useful.

Thanks

I am so close to get what I need, one variable away from happiness

Here is a very good example of what I need to do and even with the ideas suggested I still cannot figure out how to achieve what I want.

I launch a file from a CustomScriptButton, at some point I write:

Code: Select all

DeviceSetParam,1,2,Playback Transport,but16mode

but16mode is a variable that is set by the user using another button, its value is either 192(loop) or 64(play)

In a perfect world I would reference the variable but16mode using the ID of the CustomScriptButton, I came up with the following using what I learned in this thread:

Code: Select all

VValue,_tmp_pbmode,but
VAdd,_tmp_pbmode,_tmp_pbmode,MyID
VAdd,_tmp_pbmode,_tmp_pbmode,mode
DeviceSetParam,1,2,Playback Transport,_tmp_pbmode

it doesn't work, even though the value of _tmp_pbmode is but16mode the parameter is viewed as a string and not as the value referenced by that string, fair enough. I need to assign the value to another temporary variable which would be int. This is the result (_tmp_pbmode is string, _tmp_butmode is int):

Code: Select all

VValue,_tmp_pbmode,but
VAdd,_tmp_pbmode,_tmp_pbmode,MyID
VAdd,_tmp_pbmode,_tmp_pbmode,mode
VValue,_tmp_butmode,_tmp_pbmode
DeviceSetParam,1,2,Playback Transport,_tmp_butmode

Still doesn't work.

If you have any idea how to do what I want your help would be greatly appreciated.

Found a workaround, I am using labels, one per button, numbered 1000 higher, so button 1 is assigned label 1001 and so on and so forth.

then it looks like that:

Code: Select all

VValue,_temp_butID2,1000
VAdd,_tmp_butID2,_tmp_butID2,MyID
VGetLabelText,_tmp_pbmode2,_tmp_butID2
DeviceSetParam,1,2,Playback Transport,_tmp_pbmode2
