Module endbasic_std::console

Console representation and manipulation.

Re-exports

• pub use graphics::GraphicsConsole;

Modules

• drawing
  Drawing algorithms for consoles that don’t provide native rendering primitives.
• graphics
  Support to implement graphical consoles.

Structs

• CharsXY
  Represents a coordinate for character-based console operations.
• LineBuffer
  Abstraction over a string to handle manipulation operations at char boundaries.
• PixelsXY
  Represents a coordinate for pixel-based console operations.
• SizeInPixels
  Represents a rectangular size in pixels.
• TrivialConsole
  Implementation of the EndBASIC console with minimal functionality.

Enums

• AnsiColor
  Identifiers for the basic ANSI colors.
• ClearType
  Indicates what part of the console to clear on a Console::clear() call.
• Key
  Decoded key presses as returned by the console.

Traits

• Console
  Hooks to implement the commands that manipulate the console.

Functions

• ansi_color_to_rgb
  Converts an ANSI color number to an RGB color.
• get_env_var_as_u16
  Gets the value of the environment variable name and interprets it as a u16. Returns None if the variable is not set or if its contents are invalid.
• has_control_chars
  Checks if a given string has control characters.
• is_narrow
  Returns true if the console is too narrow for the standard interface.
• read_key_from_stdin
  Reads a single key from stdin when not attached to a TTY. Because characters are not visible to us until a newline is received, this reads complete lines and buffers them in memory inside the given buffer.
• read_line
  Reads a line from the console. If the console is interactive, this does fancy line editing and uses the given prompt and pre-fills the input with previous.
• read_line_secure
  Reads a line from the console without echo using the given prompt.
• refill_and_print
  Same as refill but prints the lines of each paragraph to the console instead of returning them and prefixes them with an optional indent.
• remove_control_chars
  Removes control characters from a string to make it suitable for printing.

Type Aliases

• RGB
  Represents an RGB color in [0,255] quantities.
