Module: TuiTui::TextSanitizer

Defined in:

lib/tui_tui/text_sanitizer.rb

Overview

Character-level text hygiene: keeps malformed or control bytes out of the render/input pipeline so they are displayed safely (or rejected as input) instead of raising encoding errors or emitting raw control codes.

Class Method Summary

• .printable?(string) ⇒ Boolean

  Whether ‘string` is safe to insert as literal text: every byte is a printable character (no C0 controls and no DEL).

• .sanitize(string) ⇒ Object

Class Method Details

.printable?(string) ⇒ Boolean

Whether ‘string` is safe to insert as literal text: every byte is a printable character (no C0 controls and no DEL). Multibyte UTF-8 passes, since its bytes are all >= 0x80.

Returns:

• (Boolean)

# File 'lib/tui_tui/text_sanitizer.rb', line 17

def printable?(string)
  string.bytes.all? { |byte| byte >= 0x20 && byte != 0x7F }
end

.sanitize(string) ⇒ Object

# File 'lib/tui_tui/text_sanitizer.rb', line 10

def sanitize(string)
  string.valid_encoding? ? string : string.scrub("?")
end
