question: public String trimStringToWidth ( String string , int newLength , boolean reverse ) { StringBuilder stringbuilder = new StringBuilder ( ) ; int width = 0 ; int k = reverse ? string . length ( ) - 1 : 0 ; int l = reverse ? - 1 : 1 ; boolean flag1 = false ; boolean flag2 = false ; for ( int i1 = k ; i1 >= 0 && i1 < string . length ( ) && width < newLength ; i1 += l ) { char thisChar = string . charAt ( i1 ) ; int thisWidth = getCharWidth ( thisChar ) ; if ( flag1 ) { flag1 = false ; if ( thisChar != 108 && thisChar != 76 ) { if ( thisChar == 114 || thisChar == 82 ) { flag2 = false ; } } else { flag2 = true ; } } else if ( thisWidth < 0 ) { flag1 = true ; } else { width += thisWidth ; if ( flag2 ) { ++ width ; } } if ( width > newLength ) { break ; } if ( reverse ) { stringbuilder . insert ( 0 , thisChar ) ; } else { stringbuilder . append ( thisChar ) ; } } return stringbuilder . toString ( ) ; }
target:  Trims a string to a specified width, and will reverse it if par3 is set.
