Trim Variable

[Cindy]

I was looking through previous posts for an easy way to trim white spaces from variables. All solutions were too complex!!!! I tried the following and it worked. 

Variable -> Variable Search Replace. Use the following parameters:

• Variable name: what to trim 
  
• Search: regex value "\s+\z" (find white spaces starting at the end of a string)
  
• Multi-Line: check
  
• Replaces Matches: check 
  
• Replace With: leave empty
  
• DONE
  

Please let me know if there is something easier.

Should be able to do it with two actions, Split and Join.

 

Split the variable without defining a splitter

Join the array back together without defining a joiner

 

Spaces should be gone.

Thanks for the help! That sounds like the inclusion of an array with 2 steps: (1) split and (2) join. My solution works against the original variable and has 1 step: Search and Replace. Please let me know how a 2 step solution is easier;)

Thanks,

Cindy

Your correct, two steps but....I don't use regex enough to remember all the options and syntax and Tasker does all the array stuff with you just entering your "what to trim" variable. 

 

Maybe not easier but certianly not a "too complex!!!!" solution. :-)

Thanks for the clarification easiuser. You rock!

Update - Use "\A\s+|\s+\z" to trim the beginning and end of a string.

You can also use javaScript function trim(), but it has 1 second delay, so I prefer regexp replace. Anyway, Action->Code->javaScriptlet code: var=var.trim(), where has is your tasker variable without %.
