New Features in Readline ------------------------------------------------------------------------------ This document details the changes between this version, bash-4.1-alpha, and the previous version, bash-4.0-release. 1. Changes to Bash a. Fixed bugs in the parser involving new parsing of the commands contained in command substitution when the substitution is read. b. Fixed a bug that caused the shell to dump core when performing programmable completion using a shell function. c. Fixed a bug in `mapfile' that caused it to invoke callbacks at the wrong time. d. Fixed a bug that caused the shell to dump core when listing jobs in the `exit' builtin. e. Fixed several bugs encountered when reading subscripts in associative array assignments and expansions. f. Fixed a bug that under some circumstances caused an associative array to be converted to an indexed array. g. Fixed a bug that caused syntax errors and SIGINT interrupts to not set $? to a value > 128. h. Fixed a bug that caused the shell to remove FIFOs associated with process substitution inside shell functions. i. Fixed a bug that caused terminal attributes to not be reset when the `read' builtin timed out. j. Fixed a bug in brace expansion that caused unwanted zero padding of the expanded terms. k. Fixed a bug that prevented the |& construct from working as intended when used with a simple command with additional redirections. l. Fixed a bug with the case statment ;& terminator that caused the shell to dereference a NULL pointer. m. Fixed a bug that caused assignment statements or redirections preceding a simple command name to inhibit alias expansion. n. Fixed the behavior of `set -u' to conform to the latest Posix interpretation: every expansion of an unset variable except $@ and $* will cause the shell to exit. o. Fixed a bug that caused double-quoted expansions of $* inside word expansions like ${x#$*} to not expand properly when $IFS is empty. p. Fixed a bug that caused traps to set $LINENO to the wrong value when they execute. q. Fixed a bug that caused off-by-one errors when computing history lines in the `fc' builtin. r. Fixed a bug that caused some terminating signals to not exit the shell quickly enough, forcing the kernel to send the signal (e.g., SIGSEGV) multiple times. s. Fixed a bug that caused the shell to attempt to add empty lines to the history list when reading here documents. t. Made some internal changes that dramatically speeds up sequential indexed array access. u. Fixed a bug that caused the shell to write past the end of a string when completing a double-quoted string ending in a backslash. v. Fixed a bug that caused the shell to replace too many characters when a pattern match was null in a ${foo//bar} expansion. w. Fixed bugs in the expansion of ** that caused duplicate directory names and the contents of the current directory to be omitted. x. Fixed a bug that caused $? to not be set correctly when referencing an unset variable with set -u and set -e enabled. y. Fixed a bug caused by executing an external program from the DEBUG trap while a pipeline was running. The effect was to disturb the pipeline state, occasionally causing it to hang. z. Fixed a bug that caused the ** glob expansion to dump core if it encountered an unsearchable directory. aa. Fixed a bug that caused `command -v' and `command -V' to not honor the path set by the -p option. bb. Fixed a bug that caused brace expansion to take place too soon in some compound array assignments. cc. Fixed a bug that caused programmable completion functions' changes to READLINE_POINT to not be reflected back to readline. dd. Fixed a bug that caused the shell to dump core if a trap was executed during a shell assignment statement. ee. Fixed an off-by-one error when computing the number of positional parameters for the ${@:0:n} expansion. ff. Fixed a problem with setting COMP_CWORD for programmable completion functions that could leave it set to -1. gg. Fixed a bug that caused the ERR trap to be triggered in some cases where `set -e' would not have caused the shell to exit. hh. Fixed a bug that caused changes made by `compopt' to not persist past the completion function in which compopt was executed. ii. Fixed a bug that caused the list of hostname completions to not be cleared when HOSTNAME was unset. jj. Fixed a bug that caused variable expansion in here documents to look in any temporary environment. kk. Bash and readline can now convert file names between precomposed and decomposed Unicode on Mac OS X ("keyboard" and file system forms, respectively). This affects filename completion (using new rl_filename_rewrite_hook), globbing, and readline redisplay. ll. The ERR and EXIT traps now see a non-zero value for $? when a parser error after set -e has been enabled causes the shell to exit. mm. Fixed a bug that in brace expansion that caused zero-prefixed terms to not contain the correct number of digits. nn. Fixed a bug that caused the shell to free non-allocated memory when unsetting an associative array which had had a value implicitly assigned to index "0". oo. Fixed a memory leak in the ${!prefix@} expansion. pp. Fixed a bug that caused printf to not correctly report all write errors. qq. Fixed a bug that caused single and double quotes to act as delimiters when splitting a command line into words for programmable completion. rr. Fixed a bug that caused ** globbing that caused **/path/* to match every directory, not just those matching `path'. ss. Fixed a bug that caused the shell to dump core when running `help' without arguments if the terminal width was fewer than 7 characters. 2. Changes to Readline a. The SIGWINCH signal handler now avoids calling the redisplay code if one arrives while in the middle of redisplay. b. Changes to the timeout code to make sure that timeout values greater than one second are handled better. c. Fixed a bug in the redisplay code that was triggered by a prompt containing invisible characters exactly the width of the screen. d. Fixed a bug in the redisplay code encountered when running in horizontal scroll mode. e. Fixed a bug that prevented menu completion from properly completing filenames. f. Fixed a redisplay bug caused by a multibyte character causing a line to wrap. g. Fixed a bug that caused key sequences of two characters to not be recognized when a longer sequence identical in the first two characters was bound. h. Fixed a bug that caused history expansion to be attempted on $'...' single-quoted strings. i. Fixed a bug that caused incorrect redisplay when the prompt contained multibyte characters in an `invisible' sequence bracketed by \[ and \]. j. Fixed a bug that caused history expansion to short-circuit after encountering a multibyte character. 3. New Features in Bash a. Here-documents within $(...) command substitutions may once more be delimited by the closing right paren, instead of requiring a newline. b. Bash's file status checks (executable, readable, etc.) now take file system ACLs into account on file systems that support them. c. Bash now passes environment variables with names that are not valid shell variable names through into the environment passed to child processes. d. The `execute-unix-command' readline function now attempts to clear and reuse the current line rather than move to a new one after the command executes. e. `printf -v' can now assign values to array indices. f. New `complete -E' and `compopt -E' options that work on the "empty" completion: completion attempted on an empty command line. g. New complete/compgen/compopt -D option to define a `default' completion: a completion to be invoked on command for which no completion has been defined. If this function returns 124, programmable completion is attempted again, allowing a user to dynamically build a set of completions as completion is attempted by having the default completion function install individual completion functions each time it is invoked. h. When displaying associative arrays, subscripts are now quoted. i. Changes to dabbrev-expand to make it more `emacs-like': no space appended after matches, completions are not sorted, and most recent history entries are presented first. j. The [[ and (( commands are now subject to the setting of `set -e' and the ERR trap. k. The source/. builtin now removes NUL bytes from the file before attempting to parse commands. l. There is a new configuration option (in config-top.h) that forces bash to forward all history entries to syslog. m. A new variable $BASHOPTS to export shell options settable using `shopt' to child processes. n. There is a new confgure option that forces the extglob option to be enabled by default. o. New variable $BASH_XTRACEFD; when set to an integer bash will write xtrace output to that file descriptor. p. If the optional left-hand-side of a redirection is of the form {var}, the shell assigns the file descriptor used to $var or uses $var as the file descriptor to move or close, depending on the redirection operator. q. The < and > operators to the [[ conditional command now do string comparison according to the current locale. r. Programmable completion now uses the completion for `b' instead of `a' when completion is attempted on a line like: a $(b c. s. Force extglob on temporarily when parsing the pattern argument to the == and != operators to the [[ command, for compatibility. t. Changed the behavior of interrupting the wait builtin when a SIGCHLD is received and a trap on SIGCHLD is set to be Posix-mode only. u. The read builtin has a new `-N nchars' option, which reads exactly NCHARS characters, ignoring delimiters like newline. 4. New Features in Readline a. New bindable function: menu-complete-backward. b. In the vi insertion keymap, C-n is now bound to menu-complete by default, and C-p to menu-complete-backward. c. When in vi command mode, repeatedly hitting ESC now does nothing, even when ESC introduces a bound key sequence. This is closer to how historical vi behaves. d. New bindable function: skip-csi-sequence. Can be used as a default to consume key sequences generated by keys like Home and End without having to bind all keys. e. New application-settable function: rl_filename_rewrite_hook. Can be used to rewite or modify filenames read from the file system before they are compared to the word to be completed. f. New bindable variable: skip-completed-text, active when completing in the middle of a word. If enabled, it means that characters in the completion that match characters in the remainder of the word are "skipped" rather than inserted into the line. g. The pre-readline-6.0 version of menu completion is available as "old-menu-complete" for users who do not like the readline-6.0 version. h. New bindable variable: echo-control-characters. If enabled, and the tty ECHOCTL bit is set, controls the echoing of characters corresponding to keyboard-generated signals. i. New bindable variable: enable-meta-key. Controls whether or not readline sends the smm/rmm sequences if the terminal indicates it has a meta key that enables eight-bit characters.

Update to 4.0:

2009-02-24T12:04:09Z

1. New Features in Bash a. When using substring expansion on the positional parameters, a starting index of 0 now causes $0 to be prefixed to the list. b. The `help' builtin now prints its columns with entries sorted vertically rather than horizontally. c. There is a new variable, $BASHPID, which always returns the process id of the current shell. d. There is a new `autocd' option that, when enabled, causes bash to attempt to `cd' to a directory name that is supplied as the first word of a simple command. e. There is a new `checkjobs' option that causes the shell to check for and report any running or stopped jobs at exit. f. The programmable completion code exports a new COMP_TYPE variable, set to a character describing the type of completion being attempted. g. The programmable completion code exports a new COMP_KEY variable, set to the character that caused the completion to be invoked (e.g., TAB). h. If creation of a child process fails due to insufficient resources, bash will try again several times before reporting failure. i. The programmable completion code now uses the same set of characters as readline when breaking the command line into a list of words. j. The block multiplier for the ulimit -c and -f options is now 512 when in Posix mode, as Posix specifies. k. Changed the behavior of the read builtin to save any partial input received in the specified variable when the read builtin times out. This also results in variables specified as arguments to read to be set to the empty string when there is no input available. When the read builtin times out, it returns an exit status greater than 128. l. The shell now has the notion of a `compatibility level', controlled by new variables settable by `shopt'. Setting this variable currently restores the bash-3.1 behavior when processing quoted strings on the rhs of the `=~' operator to the `[[' command. m. The `ulimit' builtin now has new -b (socket buffer size) and -T (number of threads) options. n. The -p option to `declare' now displays all variable values and attributes (or function values and attributes if used with -f). o. There is a new `compopt' builtin that allows completion functions to modify completion options for existing completions or the completion currently being executed. p. The `read' builtin has a new -i option which inserts text into the reply buffer when using readline. q. A new `-E' option to the complete builtin allows control of the default behavior for completion on an empty line. r. There is now limited support for completing command name words containing globbing characters. s. Changed format of internal help documentation for all builtins to roughly follow man page format. t. The `help' builtin now has a new -d option, to display a short description, and a -m option, to print help information in a man page-like format. u. There is a new `mapfile' builtin to populate an array with lines from a given file. The name `readarray' is a synonym. v. If a command is not found, the shell attempts to execute a shell function named `command_not_found_handle', supplying the command words as the function arguments. w. There is a new shell option: `globstar'. When enabled, the globbing code treats `**' specially -- it matches all directories (and files within them, when appropriate) recursively. x. There is a new shell option: `dirspell'. When enabled, the filename completion code performs spelling correction on directory names during completion. y. The `-t' option to the `read' builtin now supports fractional timeout values. z. Brace expansion now allows zero-padding of expanded numeric values and will add the proper number of zeroes to make sure all values contain the same number of digits. aa. There is a new bash-specific bindable readline function: `dabbrev-expand'. It uses menu completion on a set of words taken from the history list. bb. The command assigned to a key sequence with `bind -x' now sets two new variables in the environment of the executed command: READLINE_LINE_BUFFER and READLINE_POINT. The command can change the current readline line and cursor position by modifying READLINE_LINE_BUFFER and READLINE_POINT, respectively. cc. There is a new &>> redirection operator, which appends the standard output and standard error to the named file. dd. The parser now understands `|&' as a synonym for `2>&1 |', which redirects the standard error for a command through a pipe. ee. The new `;&' case statement action list terminator causes execution to continue with the action associated with the next pattern in the statement rather than terminating the command. ff. The new `;;&' case statement action list terminator causes the shell to test the next set of patterns after completing execution of the current action, rather than terminating the command. gg. The shell understands a new variable: PROMPT_DIRTRIM. When set to an integer value greater than zero, prompt expansion of \w and \W will retain only that number of trailing pathname components and replace the intervening characters with `...'. hh. There are new case-modifying word expansions: uppercase (^[^]) and lowercase (,[,]). They can work on either the first character or array element, or globally. They accept an optional shell pattern that determines which characters to modify. There is an optionally- configured feature to include capitalization operators. ii. The shell provides associative array variables, with the appropriate support to create, delete, assign values to, and expand them. jj. The `declare' builtin now has new -l (convert value to lowercase upon assignment) and -u (convert value to uppercase upon assignment) options. There is an optionally-configurable -c option to capitalize a value at assignment. kk. There is a new `coproc' reserved word that specifies a coprocess: an asynchronous command run with two pipes connected to the creating shell. Coprocs can be named. The input and output file descriptors and the PID of the coprocess are available to the calling shell in variables with coproc-specific names. ll. A value of 0 for the -t option to `read' now returns success if there is input available to be read from the specified file descriptor. mm. CDPATH and GLOBIGNORE are ignored when the shell is running in privileged mode. nn. New bindable readline functions shell-forward-word and shell-backward-word, which move forward and backward words delimited by shell metacharacters and honor shell quoting. oo. New bindable readline functions shell-backward-kill-word and shell-kill-word which kill words backward and forward, but use the same word boundaries as shell-forward-word and shell-backward-word. 2. New Features in Readline a. A new variable, rl_sort_completion_matches; allows applications to inhibit match list sorting (but beware: some things don't work right if applications do this). b. A new variable, rl_completion_invoking_key; allows applications to discover the key that invoked rl_complete or rl_menu_complete. c. The functions rl_block_sigint and rl_release_sigint are now public and available to calling applications who want to protect critical sections (like redisplay). d. The functions rl_save_state and rl_restore_state are now public and available to calling applications; documented rest of readline's state flag values. e. A new user-settable variable, `history-size', allows setting the maximum number of entries in the history list. f. There is a new implementation of menu completion, with several improvements over the old; the most notable improvement is a better `completions browsing' mode. g. The menu completion code now uses the rl_menu_completion_entry_function variable, allowing applications to provide their own menu completion generators. h. There is support for replacing a prefix of a pathname with a `...' when displaying possible completions. This is controllable by setting the `completion-prefix-display-length' variable. Matches with a common prefix longer than this value have the common prefix replaced with `...'. i. There is a new `revert-all-at-newline' variable. If enabled, readline will undo all outstanding changes to all history lines when `accept-line' is executed. j. If the kernel supports it, readline displays special characters corresponding to a keyboard-generated signal when the signal is received.
