1 This is a terse description of the new features added to readline-5.1 since
2 the release of readline-5.0.
4 1. New Features in Readline
6 a. The key sequence sent by the keypad `delete' key is now automatically
9 b. A negative argument to menu-complete now cycles backward through the
12 c. A new bindable readline variable: bind-tty-special-chars. If non-zero,
13 readline will bind the terminal special characters to their readline
14 equivalents when it's called (on by default).
16 d. New bindable command: vi-rubout. Saves deleted text for possible
17 reinsertion, as with any vi-mode `text modification' command; `X' is bound
18 to this in vi command mode.
20 e. If the rl_completion_query_items is set to a value < 0, readline never
21 asks the user whether or not to view the possible completions.
23 f. New application-callable auxiliary function, rl_variable_value, returns
24 a string corresponding to a readline variable's value.
26 g. When parsing inputrc files and variable binding commands, the parser
27 strips trailing whitespace from values assigned to boolean variables
30 h. A new external application-controllable variable that allows the LINES
31 and COLUMNS environment variables to set the window size regardless of
32 what the kernel returns.
