Type that handles actions from the parser

XXX Should probably not provide default impls for everything, but it makes writing specific handler impls for tests far easier.

Provided methods

fn set_title(&mut self, _: &str)

OSC to set window title

fn set_mouse_cursor(&mut self, _: MouseCursor)

Set the window's mouse cursor

fn set_cursor_style(&mut self, _: Option<CursorStyle>)

Set the cursor style

fn input(&mut self, _c: char)

A character to be displayed

fn goto(&mut self, _: Line, _: Column)

Set cursor to position

fn goto_line(&mut self, _: Line)

Set cursor to specific row

fn goto_col(&mut self, _: Column)

Set cursor to specific column

fn insert_blank(&mut self, _: Column)

Insert blank characters in current line starting from cursor

fn move_up(&mut self, _: Line)

Move cursor up rows

fn move_down(&mut self, _: Line)

Move cursor down rows

fn identify_terminal<W: Write>(&mut self, _: &mut W)

Identify the terminal (should write back to the pty stream)

TODO this should probably return an io::Result

fn device_status<W: Write>(&mut self, _: &mut W, _: usize)

fn move_forward(&mut self, _: Column)

Move cursor forward cols

fn move_backward(&mut self, _: Column)

Move cursor backward cols

fn move_down_and_cr(&mut self, _: Line)

Move cursor down rows and set to column 1

fn move_up_and_cr(&mut self, _: Line)

Move cursor up rows and set to column 1

fn put_tab(&mut self, _count: i64)

Put count tabs

fn backspace(&mut self)

Backspace count characters

fn carriage_return(&mut self)

Carriage return

fn linefeed(&mut self)

Linefeed

fn bell(&mut self)

Ring the bell

Hopefully this is never implemented

fn substitute(&mut self)

Substitute char under cursor

fn newline(&mut self)

Newline

fn set_horizontal_tabstop(&mut self)

Set current position as a tabstop

fn scroll_up(&mut self, _: Line)

Scroll up rows rows

fn scroll_down(&mut self, _: Line)

Scroll down rows rows

fn insert_blank_lines(&mut self, _: Line)

Insert count blank lines

fn delete_lines(&mut self, _: Line)

Delete count lines

fn erase_chars(&mut self, _: Column)

Erase count chars in current line following cursor

Erase means resetting to the default state (default colors, no content, no mode flags)

fn delete_chars(&mut self, _: Column)

Delete count chars

Deleting a character is like the delete key on the keyboard - everything to the right of the deleted things is shifted left.

fn move_backward_tabs(&mut self, _count: i64)

Move backward count tabs

fn move_forward_tabs(&mut self, _count: i64)

Move forward count tabs

fn save_cursor_position(&mut self)

Save current cursor position

fn restore_cursor_position(&mut self)

Restore cursor position

fn clear_line(&mut self, _mode: LineClearMode)

Clear current line

fn clear_screen(&mut self, _mode: ClearMode)

Clear screen

fn clear_tabs(&mut self, _mode: TabulationClearMode)

Clear tab stops

fn reset_state(&mut self)

Reset terminal state

fn reverse_index(&mut self)

Reverse Index

Move the active position to the same horizontal position on the preceding line. If the active position is at the top margin, a scroll down is performed

fn terminal_attribute(&mut self, _attr: Attr)

set a terminal attribute

fn set_mode(&mut self, _mode: Mode)

Set mode

fn unset_mode(&mut self, _: Mode)

Unset mode

fn set_scrolling_region(&mut self, _: Range<Line>)

DECSTBM - Set the terminal scrolling region

fn set_keypad_application_mode(&mut self)

DECKPAM - Set keypad to applications mode (ESCape instead of digits)

fn unset_keypad_application_mode(&mut self)

DECKPNM - Set keypad to numeric mode (digits instead of ESCape seq)

fn set_active_charset(&mut self, _: CharsetIndex)

Set one of the graphic character sets, G0 to G3, as the active charset.

'Invoke' one of G0 to G3 in the GL area. Also referred to as shift in, shift out and locking shift depending on the set being activated

fn configure_charset(&mut self, _: CharsetIndex, _: StandardCharset)

Assign a graphic character set to G0, G1, G2 or G3

'Designate' a graphic character set as one of G0 to G3, so that it can later be 'invoked' by set_active_charset

fn set_color(&mut self, _: usize, _: Rgb)

Set an indexed color value

fn reset_color(&mut self, _: usize)

Reset an indexed color to original value

fn set_clipboard(&mut self, _: &str)

Set the clipboard

fn dectest(&mut self)

Run the dectest routine

Implementors

impl Handler for Term[src]

fn set_title(&mut self, title: &str)[src]

Set the window title

fn set_mouse_cursor(&mut self, cursor: MouseCursor)[src]

Set the mouse cursor

fn input(&mut self, c: char)[src]

A character to be displayed

fn backspace(&mut self)[src]

Backspace count characters

fn carriage_return(&mut self)[src]

Carriage return

fn linefeed(&mut self)[src]

Linefeed

fn bell(&mut self)[src]

Set current position as a tabstop

fn newline(&mut self)[src]

Run LF/NL

LF/NL mode has some interesting history. According to ECMA-48 4th edition, in LINE FEED mode,

The execution of the formatter functions LINE FEED (LF), FORM FEED (FF), LINE TABULATION (VT) cause only movement of the active position in the direction of the line progression.

In NEW LINE mode,

The execution of the formatter functions LINE FEED (LF), FORM FEED (FF), LINE TABULATION (VT) cause movement to the line home position on the following line, the following form, etc. In the case of LF this is referred to as the New Line (NL) option.

Additionally, ECMA-48 4th edition says that this option is deprecated. ECMA-48 5th edition only mentions this option (without explanation) saying that it's been removed.

As an emulator, we need to support it since applications may still rely on it.

fn set_color(&mut self, index: usize, color: Rgb)[src]

Set the indexed color value

fn reset_color(&mut self, index: usize)[src]

Reset the indexed color to original value

fn set_clipboard(&mut self, string: &str)[src]

Set the clipboard

fn terminal_attribute(&mut self, attr: Attr)[src]

set a terminal attribute
