Text and Crypto

Text

Implementation status: thin wrappers Fmt / Regex / Encoding / StringBuilder / Bytes Implemented.

Type	Typical API
Fmt	print / printLine / debug take Sendable; format(..., args: Array<Sendable>) (R-12; ≠ Object)
Regex	isMatch / findAll / replaceAll
Encoding	base64Encode / hexEncode
Bytes / StringBuilder	Buffered concatenation

Built-in string methods (split, matches) still come from CORE, so import Text is unnecessary.

Crypto

Implementation status: Crypto.sha256 and others Implemented (Host). For dynamic plugins, see also examples/plugin_demo and Language Guide · Runtime Extensions.

import Crypto

func main() {
    print(Crypto.sha256("data"))
}
