Remove text formatting and non-alphanumeric characters

[McScripta]

I'm trying to have a field format its content as all caps and assign the font / size as I indicate in the Inspector panel. I also need to remove all non-alphanumeric characters from the input.

Generally speaking it works ok other than despite "Synchronized with field's font" being selected for the field, input pasted from a pdf string for instance retains its source formatting (or at least does not apply field's formatting). I though of maybe stripping the formatting through calculation rather than to rely on Inspector settings.

...I get weird results though, input appears twice in the field. Clearly I messed something up in this function.... any help?

 

TextFormatRemove ( Self ) & Filter ( Self ; "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789" )

input appears twice in the field.

 

TextFormatRemove ( Self ) & Filter ( Self ; "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789" )

 

That's because you are calculating the input twice, then concatenating the results with the '&' operator.

 

Instead, you need to apply the second function to the result of the first one:

TextFormatRemove ( Filter ( Self ; "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789" ) )

or (formatted differently)

TextFormatRemove ( 
  Filter ( 
    Self ; "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789" 
  ) 
)

or (using Let() to calculate an intermediate result)

Let (
  res = Filter ( Self ; "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789" ) ;
  TextFormatRemove ( res )
)
