Annotation of embedaddon/readline/NEWS, revision 1.1.1.1

1.1       misho       1: This is a terse description of the new features added to readline-6.3 since
                      2: the release of readline-6.2.
                      3: 
                      4: New Features in Readline
                      5: 
                      6: a.  Readline is now more responsive to SIGHUP and other fatal signals when
                      7:     reading input from the terminal or performing word completion but no
                      8:     longer attempts to run any not-allowable functions from a signal handler
                      9:     context.
                     10: 
                     11: b.  There are new bindable commands to search the history for the string of
                     12:     characters between the beginning of the line and the point
                     13:     (history-substring-search-forward, history-substring-search-backward)
                     14: 
                     15: c.  Readline allows quoted strings as the values of variables when setting
                     16:     them with `set'.  As a side effect, trailing spaces and tabs are ignored
                     17:     when setting a string variable's value.
                     18: 
                     19: d.  The history library creates a backup of the history file when writing it
                     20:     and restores the backup on a write error.
                     21: 
                     22: e.  New application-settable variable: rl_filename_stat_hook: a function called
                     23:     with a filename before using it in a call to stat(2).  Bash uses it to
                     24:     expand shell variables so things like $HOME/Downloads have a slash
                     25:     appended.
                     26: 
                     27: f.  New bindable function `print-last-kbd-macro', prints the most-recently-
                     28:     defined keyboard macro in a reusable format.
                     29: 
                     30: g.  New user-settable variable `colored-stats', enables use of colored text
                     31:     to denote file types when displaying possible completions (colored analog
                     32:     of visible-stats).
                     33: 
                     34: h.  New user-settable variable `keyseq-timout', acts as an inter-character
                     35:     timeout when reading input or incremental search strings.
                     36: 
                     37: i.  New application-callable function: rl_clear_history. Clears the history list
                     38:     and frees all readline-associated private data.
                     39: 
                     40: j.  New user-settable variable, show-mode-in-prompt, adds a characters to the
                     41:     beginning of the prompt indicating the current editing mode.
                     42: 
                     43: k.  New application-settable variable: rl_input_available_hook; function to be
                     44:     called when readline detects there is data available on its input file
                     45:     descriptor.
                     46: 
                     47: l.  Readline calls an application-set event hook (rl_event_hook) after it gets
                     48:     a signal while reading input (read returns -1/EINTR but readline does not
                     49:     handle the signal immediately) to allow the application to handle or
                     50:     otherwise note it.
                     51: 
                     52: m.  If the user-settable variable `history-size' is set to a value less than
                     53:     0, the history list size is unlimited.
                     54: 
                     55: n.  New application-settable variable: rl_signal_event_hook; function that is
                     56:     called when readline is reading terminal input and read(2) is interrupted
                     57:     by a signal.  Currently not called for SIGHUP or SIGTERM.
