The syntax of compareTo() function is fun String.compareTo( other Returns the first character having the smallest value according to the provided comparator or null if there are no characters. Returns a string containing characters of the original string at the specified range of indices. And multiline string keeping extra left spaces is just crazy. Help is never far away – consult extensive community resources Returns a single list of all elements yielded from results of transform function being invoked on each character of original char sequence. It would probably be best implemented in an optimistic fashion (assuming that it doesn’t need to wrap). Parses the string as an ULong number and returns the result Kotlin 1.3.40 will actually support intrinsics for these functions, see https://youtrack.jetbrains.com/issue/KT-17755. where key is provided by the keySelector function applied to each character of the given char sequence where key is provided by the keySelector function and Prepends indent to every line of the original string. So if you’re debugging this code, and you want to log the exact query string, or copy paste it into an sqlite3 (or your SQL client of choice) to play around with it, it’s going to be ugly. using the specified locale. Kotlin - Split String to Lines - To split string to lines in Kotlin programming, you may use String.lines() function. Maybe something like this would be good enough for you? is a string literal. The returned list has length of the shortest char sequence. Returns the string if it is not null, or the empty string otherwise. Returns a character at the given index or null if the index is out of bounds of this char sequence. Otherwise returns this string unchanged. Otherwise, returns this string. An array of characters is called a string. and value is the character itself. Parses the string as an UInt number and returns the result. Parses the string as a UShort number and returns the result. if and only if it starts with and ends with the delimiter. lines if they are blank (notice difference blank vs empty). Applies the given transform function to each character of the original char sequence Returns a sequence of snapshots of the window of the given size Powered by Discourse, best viewed with JavaScript enabled, return lines map { it.replaceAll("^\s*|", “”) } join “n”, Multiline string literal indent handling is unconvient, https://eclipse.org/xtend/documentation/203_xtend_expressions.html#templates, https://youtrack.jetbrains.com/issue/KT-17755. Accumulates value starting with initial value and applying operation from left to right Parses the string as a java.math.BigInteger number and returns the result. Iterator for characters of the given char sequence. so that strings can be split or matched on. Returns the smallest value among all values produced by selector function Returns a copy of this string converted to lower case using the rules of the specified locale. If this string ends with the given suffix, returns a copy of this string Returns a new string obtained by replacing each substring of this char sequence that matches the given regular expression Returns true if this CharSequence has Unicode surrogate pair at the specified index. to each character, its index in the original char sequence and current accumulator value that starts with the first character of this char sequence. Removes the given delimiter string from both the start and the end of this string to each character and its index in the original char sequence. Returns this char sequence if it is not empty and doesn't consist solely of whitespace characters, sliding along this char sequence with the given step, where each Returns a Map containing key-value pairs provided by transform function Parses the string as a java.math.BigDecimal number and returns the result with the result of the given function transform that takes MatchResult and returns a string to be used as a starting at the specified startIndex and ending right before the specified endIndex. Returns a new MutableList filled with all characters of this char sequence. Returns true if no characters match the given predicate. Groups values returned by the valueTransform function applied to each character of the original char sequence starting from the specified startIndex and optionally ignoring the case. Removes the part of a string at a given range. Finds the index of the last occurrence of any of the specified strings in this char sequence, Returns the index of the last character in the char sequence or -1 if it is empty. Would be very nice to have such a functionality. Splits this char sequence to a sequence of lines delimited by any of the following character sequences: CRLF, LF or CR. Replace part of string after the last occurrence of given delimiter with the replacement string. Always and without exception, checked and optimized at compile time. Creates a Sequence instance that wraps the original char sequence returning its characters when being iterated. Parses the string as a java.math.BigDecimal number and returns the result. }. Replaces the first occurrence of the given regular expression regex in this char sequence with specified replacement expression. Returns the largest value according to the provided comparator Finds the index of the first occurrence of any of the specified chars in this char sequence, Returns true if at least one character matches the given predicate. or null if the string is not a valid representation of a number. Returns a list containing successive accumulation values generated by applying operation from left to right Populates and returns the destination mutable map with key-value pairs, Returns zero if this object is equal Kotlin – Split String Kotlin Split String using a given set of delimiters or Regular Expression – Splitting a string to parts by delimiters is useful when the string contains many (parametric) values separated by delimiters or if the string resembles a regular expression. starting from the specified startIndex. to each character and current accumulator value that starts with the first character of this char sequence. Returns a list of pairs of each two adjacent characters in this char sequence. Accumulates value starting with initial value and applying operation from right to left by the key returned by the given keySelector function applied to the character or we can call the toRegex method on a String: "a applied to each character and puts to the destination map each group key associated with a list of corresponding characters. Finds the first occurrence of any of the specified strings in this char sequence, And multiline string keeping extra left spaces is just crazy. to current accumulator value and each character with its index in the original char sequence. starting from the specified startIndex and optionally ignoring the case. This article will show you a few ways to declare and use a multi-line string in Java. If locale is null then no localization is applied. with the suffix removed. Returns a copy of this string having its first letter titlecased using the rules of the specified locale, Replace part of string before the last occurrence of given delimiter with the replacement string. and applies the given transform function to an each. Splits this char sequence into several char sequences each not exceeding the given size Returns the index within this char sequence of the first occurrence of the specified string, Otherwise, returns this string. Returns true if a substring of this char sequence starting at the specified offset startIndex starts with the specified prefix. For among all values produced by selector function applied to each character in the char sequence. Applies the given transform function to each character and its index in the original char sequence I don’t know what would be the best rule the follow when removing this extra spaces, but I am sure it is possible Xtend has solved this really nicely: Their API’s are kind of frozen by default anyway. Uses this string as a format string and returns a string obtained by substituting the specified arguments, A lot of time I write SQLs, HTML and other similar things in my code. to each character in the original char sequence. Creates a range from this Comparable value to the specified that value. If the string does not contain the delimiter, returns missingDelimiterValue which defaults to the original string. Returns a list of snapshots of the window of the given size I don’t have real numbers for this but I’d imagine that in most cases a multiline string in a dynamic trimMargin is just a bug and not intended, so maybe changing this is not as bad of a breaking change than it seems. The String class represents character strings. Returns the first character having the largest value according to the provided comparator or null if there are no characters. Correct me if I’m wrong but I don’t think tirmMargin or trimIndent are ever used with dynamic multiline strings. Returns true if char sequence has at least one character. Returns true if this char sequence is not empty and contains some characters except of whitespace characters. Returns a copy of this string converted to upper case using the rules of the specified locale. Returns the last character matching the given predicate, or null if no such character was found. Returns the character (Unicode code point) before the specified index. Returns a string having leading characters matching the predicate removed. Returns a list containing the results of applying the given transform function starting from the specified startIndex and optionally ignoring the case. Returns true if this char sequence is empty (contains no characters). or the result of calling defaultValue function otherwise. to each character and current accumulator value. Using compareTo() extension function Kotlin provides compareTo() extension function to String. https://eclipse.org/xtend/documentation/203_xtend_expressions.html#templates. Converts the string into a regular expression Regex with the specified single option. Parses the string as an UInt number and returns the result Returns index of the first character matching the given predicate, or -1 if the char sequence does not contain such character. Returns true if the char sequence has no characters. and appends only the non-null results to the given destination. I don’t know what would be the best rule the follow when removing this extra spaces, but I am sure it is possible to figure out some solution. Kotlin strings are mostly similar to Java strings but has some new added functionalities. Returns the last character, or null if the char sequence is empty. It's inspired by the same method `stripMargin` in Scala: fun String.stripMargin(): String { The nice thing about standard libraries is that functions from it can be replaced by intrinsics if so desired.   return lines map { it.replaceAll("^\s*|", “”) } join “n” If these functions could now be defined as constexpr and evaluated at compile time your problem would go away. Returns the last character matching the given predicate. Doesn't affect a line if it doesn't contain marginPrefix except the first and the last blank lines.
