Text String Utilities

• DH_LeftString:
  Given a text string and a length n, outputs the string's n leftmost characters.

   

• DH_RightString:
  Given a text string and a length n, outputs the string's n rightmost characters.

   

• DH_SubString:
  Given a text string, a start position s, and a length n, outputs n characters from the string starting at position s.

   

• DH_StringCompare:
  Given 2 text strings, sets Bool outputs to indicate if the first string equals the second, or if unequal, which string sorts before the other. By default, the comparison is case-sensitive. To compare without regard to case, set the Case Insensitive input to TRUE. The output pins are interpreted as follows:
  
  Text 1 < Text 2 - TRUE if Text 1 sorts before Text 2, otherwise FALSE.

  Text 1 = Text 2 - TRUE if Text 1 equals Text 2, otherwise FALSE.

  Text 1 > Text 2 - TRUE if Text 1 sorts after Text 2, otherwise FALSE.

  As with the Numeric Comparison Modules, these Boolean outputs can be combined using the DH Boolean Logic modules, and used to trigger actions by connecting them to DH_BoolToFloat or DH_BoolToVoltage modules.

   

• DH_StringSearch:
  Given 2 text strings and a start position s, searches for an occurrence of the second string in the first, starting at position s in the first string. Outputs the position at which the search string was found, or -1 if it was not found. By default, searches left to right. To search right to left, set the Right to Left input to TRUE.

   

• DH_StringLength:
  Given a text string, outputs the number of characters it contains.

Notes:

String positions are always indexed from 0 as the first character of the string. The position of the last character of the string is 1 less than the string's length.
