NEWS revision 136644
1This is a terse description of the new features added to readline-5.0 since 2the release of readline-4.3. 3 41. New Features in Readline 5 6a. History expansion has a new `a' modifier equivalent to the `g' modifier 7 for compatibility with the BSD csh. 8 9b. History expansion has a new `G' modifier equivalent to the BSD csh `g' 10 modifier, which performs a substitution once per word. 11 12c. All non-incremental search operations may now undo the operation of 13 replacing the current line with the history line. 14 15d. The text inserted by an `a' command in vi mode can be reinserted with 16 `.'. 17 18e. New bindable variable, `show-all-if-unmodified'. If set, the readline 19 completer will list possible completions immediately if there is more 20 than one completion and partial completion cannot be performed. 21 22f. There is a new application-callable `free_history_entry()' function. 23 24g. History list entries now contain timestamp information; the history file 25 functions know how to read and write timestamp information associated 26 with each entry. 27 28h. Four new key binding functions have been added: 29 30 rl_bind_key_if_unbound() 31 rl_bind_key_if_unbound_in_map() 32 rl_bind_keyseq_if_unbound() 33 rl_bind_keyseq_if_unbound_in_map() 34 35i. New application variable, rl_completion_quote_character, set to any 36 quote character readline finds before it calls the application completion 37 function. 38 39j. New application variable, rl_completion_suppress_quote, settable by an 40 application completion function. If set to non-zero, readline does not 41 attempt to append a closing quote to a completed word. 42 43k. New application variable, rl_completion_found_quote, set to a non-zero 44 value if readline determines that the word to be completed is quoted. 45 Set before readline calls any application completion function. 46 47l. New function hook, rl_completion_word_break_hook, called when readline 48 needs to break a line into words when completion is attempted. Allows 49 the word break characters to vary based on position in the line. 50 51m. New bindable command: unix-filename-rubout. Does the same thing as 52 unix-word-rubout, but adds `/' to the set of word delimiters. 53 54n. When listing completions, directories have a `/' appended if the 55 `mark-directories' option has been enabled. 56
