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