* Todo list:
|
|
* - Filter bogus Ctrl+<char> combinations.

|
* Bloat:
|
|
* - History search like Ctrl+r in readline?

|
|
* List of escape sequences used by this program, we do everything just
|
|
* with three sequences. In order to be so cheap we may have some
|
|
* flickering effect with some slow terminal, but the lesser sequences
|
|
* the more compatible.
|
|
*
|
|
* EL (Erase Line)
|
|
* Sequence: ESC [ n K
|
|
* Effect: if n is 0 or missing, clear from cursor to end of line
|
|
* Effect: if n is 1, clear from beginning of line to cursor
|
|
* Effect: if n is 2, clear entire line
|
|
*
|
|
* CUF (CUrsor Forward)
|
|
* Sequence: ESC [ n C
|
|
* Effect: moves cursor forward n chars
|
|
*
|
|
* CUB (CUrsor Backward)
|
|
* Sequence: ESC [ n D
|
|
* Effect: moves cursor backward n chars
|
|
*
|
|
* The following is used to get the terminal width if getting
|
|
* the width with the TIOCGWINSZ ioctl fails
|
|
*
|
|
* DSR (Device Status Report)
|
|
* Sequence: ESC [ 6 n
|
|
* Effect: reports the current cursor position as ESC [ n ; m R
|
|
* where n is the row and m is the column
|
|
*
|
|
* When multi line mode is enabled, we also use an additional escape
|
|
* sequence. However multi line editing is disabled by default.
|
|
*
|
|
* CUU (Cursor Up)
|
|
* Sequence: ESC [ n A
|
|
* Effect: moves cursor up of n chars.
|
|
*
|
|
* CUD (Cursor Down)
|
|
* Sequence: ESC [ n B
|
|
* Effect: moves cursor down of n chars.
|
|
*
|
|
* When linenoiseClearScreen() is called, two additional escape sequences
|
|
* are used in order to clear the screen and position the cursor at home
|
|
* position.
|
|
*
|
|
* CUP (Cursor position)
|
|
* Sequence: ESC [ H
|
|
* Effect: moves the cursor to upper left corner
|
|
*
|
|
* ED (Erase display)
|
|
* Sequence: ESC [ 2 J
|
|
* Effect: clear the whole screen
