Strings

Strings are a sequence of a characters. Strings are immutable, which means that once a string is created, it cannot be changed. Tact have a limitied support for strings, but you can use them to store text. Strings are also useful as comment messages body.

beginString

fun beginString(): StringBuilder;

Creates new empty StringBuilder.

beginComment

fun beginComment(): StringBuilder;

Creates new empty StringBuilder for comment.

beginTailString

fun beginTailString(): StringBuilder;

Creates new empty StringBuilder for a tailstring. This format is used in various standards like NFT or Jetton.

beginStringFromBuilder

fun beginStringFromBuilder(builder: Builder): StringBuilder;

Creates new StringBuilder from existing builder. Useful if you need to serialize string to a cell with some other data.

StringBuilder.append

extends mutates fun append(self: StringBuilder, s: String);

Append to StringBuilder self String s and updates it.

StringBuilder.toString

extends fun toString(self: StringBuilder): String;

Assembles a string from a builder's content.

StringBuilder.toCell

extends fun toCell(self: StringBuilder): Cell

Assembles a cell from a builder's content.

StringBuilder.toSlice

extends fun toSlice(self: StringBuilder): Slice;

Assembles a cell from builder's content into a slice. Alias to self.toCell().asSlice().

Int.toString

extends fun toString(self: Int): String;

Converts Int value to String

Int.toFloatString

extends fun toFloatString(self: Int, digits: Int): String

Converts Fixed Float value that represented as Int to String

Where,

self significant part of float number as Int number;
digits is a exponentiation parameter of expression 10^(-digits) that will be used for computing float number. digits required to be 0 <= digits < 77.

Int.toCoinsString

extends fun toCoinsString(self: Int): String

Converts nanoToncoin Int value self to String float number of Toncoins and returns it as a result.

String.asComment

extends fun asComment(self: String): Cell

Converts String self to comment message body Cell.

String.asSlice

extends fun asSlice(self: String): Slice;

Dangerously casts string as slice for future parsing. Use it only if you know what you are doing.

Slice.asString

extends fun asString(self: Slice): String;

Dangerously casts slice as string. Use it only if you know what you are doing.

String.fromBase64

extends fun fromBase64(self: String): Slice;

Decodes base64 string to a slice. NOTE: This method is very limited and can be used only for small strings that fits a single cell.

Slice.fromBase64

extends fun fromBase64(self: Slice): Slice;

Decodes base64 slice to a slice. Alias for self.asString().fromBase64()
