This is a terse description of the new features added to readline-5.0 since
|
||
|
|
the release of readline-4.3.
|
||
|
|
|
||
|
|
1. New Features in Readline
|
||
|
|
|
||
|
|
a. History expansion has a new `a' modifier equivalent to the `g' modifier
|
||
|
|
for compatibility with the BSD csh.
|
||
|
|
|
||
|
|
b. History expansion has a new `G' modifier equivalent to the BSD csh `g'
|
||
|
|
modifier, which performs a substitution once per word.
|
||
|
|
|
||
|
|
c. All non-incremental search operations may now undo the operation of
|
||
|
|
replacing the current line with the history line.
|
||
|
|
|
||
|
|
d. The text inserted by an `a' command in vi mode can be reinserted with
|
||
|
|
`.'.
|
||
|
|
|
||
|
|
e. New bindable variable, `show-all-if-unmodified'. If set, the readline
|
||
|
|
completer will list possible completions immediately if there is more
|
||
|
|
than one completion and partial completion cannot be performed.
|
||
|
|
|
||
|
|
f. There is a new application-callable `free_history_entry()' function.
|
||
|
|
|
||
|
|
g. History list entries now contain timestamp information; the history file
|
||
|
|
functions know how to read and write timestamp information associated
|
||
|
|
with each entry.
|
||
|
|
|
||
|
|
h. Four new key binding functions have been added:
|
||
|
|
|
||
|
|
rl_bind_key_if_unbound()
|
||
|
|
rl_bind_key_if_unbound_in_map()
|
||
|
|
rl_bind_keyseq_if_unbound()
|
||
|
|
rl_bind_keyseq_if_unbound_in_map()
|
||
|
|
|
||
|
|
i. New application variable, rl_completion_quote_character, set to any
|
||
|
|
quote character readline finds before it calls the application completion
|
||
|
|
function.
|
||
|
|
|
||
|
|
j. New application variable, rl_completion_suppress_quote, settable by an
|
||
|
|
application completion function. If set to non-zero, readline does not
|
||
|
|
attempt to append a closing quote to a completed word.
|
||
|
|
|
||
|
|
k. New application variable, rl_completion_found_quote, set to a non-zero
|
||
|
|
value if readline determines that the word to be completed is quoted.
|
||
|
|
Set before readline calls any application completion function.
|
||
|
|
|
||
|
|
l. New function hook, rl_completion_word_break_hook, called when readline
|
||
|
|
needs to break a line into words when completion is attempted. Allows
|
||
|
|
the word break characters to vary based on position in the line.
|
||
|
|
|
||
|
|
m. New bindable command: unix-filename-rubout. Does the same thing as
|
||
|
|
unix-word-rubout, but adds `/' to the set of word delimiters.
|
||
|
|
|
||
|
|
n. When listing completions, directories have a `/' appended if the
|
||
|
|
`mark-directories' option has been enabled.
