Changes to Readline + +a. Changed the HTML documents so that the table-of-contents is no longer + a separate file. + +b. Changes to the shared object configuration for: Irix 5.x, Irix 6.x, + OSF/1. + +c. The shared library major and minor versions are now constructed + automatically by configure and substituted into the makefiles. + +d. It's now possible to install the shared libraries separately from the + static libraries. + +e. The history library tries to truncate the history file only if it is a + regular file. + +f. A bug that caused _rl_dispatch to address negative array indices on + systems with signed chars was fixed. + +g. rl-yank-nth-arg now leaves the history position the same as when it was + called. + +h. Changes to the completion code to handle MS-DOS drive-letter:pathname + filenames. + +i. Completion is now case-insensitive by default on MS-DOS. + +j. Fixes to the history file manipulation code for MS-DOS. + +k. Readline attempts to bind the arrow keys to appropriate defaults on MS-DOS. + +l. Some fixes were made to the redisplay code for better operation on MS-DOS. + +m. The quoted-insert code will now insert tty special chars like ^C. + +n. A bug was fixed that caused the display code to reference memory before + the start of the prompt string. + +o. More support for __EMX__ (OS/2). + +p. A bug was fixed in readline's signal handling that could cause infinite + recursion in signal handlers. + +q. A bug was fixed that caused the point to be less than zero when rl_forward + was given a very large numeric argument. + +r. The vi-mode code now gets characters via the application-settable value + of rl_getc_function rather than calling rl_getc directly. + +s. The history file code now uses O_BINARY mode when reading and writing + the history file on cygwin32. + +t. Fixed a bug in the redisplay code for lines with more than 256 line + breaks. + +u. A bug was fixed which caused invisible character markers to not be + stripped from the prompt string if the terminal was in no-echo mode. + +v. Readline no longer tries to get the variables it needs for redisplay + from the termcap entry if the calling application has specified its + own redisplay function. Readline treats the terminal as `dumb' in + this case. + +w. Fixes to the SIGWINCH code so that a multiple-line prompt with escape + sequences is redrawn correctly. + +x. Changes to the install and install-shared targets so that the libraries + and header files are installed separately. + +2. New Features in Readline + +a. A new Readline `user manual' is in doc/rluserman.texinfo. + +b. Parentheses matching is now always compiled into readline, and enabled + or disabled when the value of the `blink-matching-paren' variable is + changed. + +c. MS-DOS systems now use ~/_inputrc as the last-ditch inputrc filename. + +d. MS-DOS systems now use ~/_history as the default history file. + +e. history-search-{forward,backward} now leave the point at the end of the + line when the string to search for is empty, like + {reverse,forward}-search-history. + +f. history-search-{forward,backward} now leave the last history line found + in the readline buffer if the second or subsequent search fails. + +g. New function for use by applications: rl_on_new_line_with_prompt, used + when an application displays the prompt itself before calling readline(). + +h. New variable for use by applications: rl_already_prompted. An application + that displays the prompt itself before calling readline() must set this to + a non-zero value. + +i. A new variable, rl_gnu_readline_p, always 1. The intent is that an + application can verify whether or not it is linked with the `real' + readline library or some substitute. + +j. Per Bothner's `rlfe' (pronounced `Ralphie') readline front-end program + is included in the examples subdirectory, though it is not built + by default. + +------------------------------------------------------------------------------- This document details the changes between this version, readline-4.0, and the previous version, readline-2.2. diff --git a/readline/COPYING b/readline/COPYING index a43ea2126fb..1bf15263878 100644 --- a/readline/COPYING +++ b/readline/COPYING @@ -2,7 +2,7 @@ Version 2, June 1991 Copyright (C) 1989, 1991 Free Software Foundation, Inc. - 675 Mass Ave, Cambridge, MA 02139, USA + 59 Temple Place, Suite 330, Boston, MA 02111 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. @@ -305,7 +305,7 @@ the "copyright" line and a pointer to where the full notice is found.
