Changes to Readline + +a. When setting the terminal attributes on systems using `struct termio', + readline waits for output to drain before changing the attributes. + +b. A fix was made to the history word tokenization code to avoid attempts to + dereference a null pointer. + +c. Readline now defaults rl_terminal_name to $TERM if the calling application + has left it unset, and tries to initialize with the resultant value. + +d. Instead of calling (*rl_getc_function)() directly to get input in certain + places, readline now calls rl_read_key() consistently. + +e. Fixed a bug in the completion code that allowed a backslash to quote a + single quote inside a single-quoted string. + +f. rl_prompt is no longer assigned directly from the argument to readline(), + but uses memory allocated by readline. This allows constant strings to + be passed to readline without problems arising when the prompt processing + code wants to modify the string. + +g. Fixed a bug that caused non-interactive history searches to return the + wrong line when performing multiple searches backward for the same string. + +h. Many variables, function arguments, and function return values are now + declared `const' where appropriate, to improve behavior when linking with + C++ code. + +i. The control character detection code now works better on systems where + `char' is unsigned by default. + +j. The vi-mode numeric argument is now capped at 999999, just like emacs mode. + +k. The Function, CPFunction, CPPFunction, and VFunction typedefs have been + replaced with a set of specific prototyped typedefs, though they are + still in the readline header files for backwards compatibility. + +m. Nearly all of the (undocumented) internal global variables in the library + now have an _rl_ prefix -- there were a number that did not, like + screenheight, screenwidth, alphabetic, etc. + +n. The ding() convenience function has been renamed to rl_ding(), though the + old function is still defined for backwards compatibility. + +o. The completion convenience functions filename_completion_function, + username_completion_function, and completion_matches now have an rl_ + prefix, though the old names are still defined for backwards compatibility. + +p. The functions shared by readline and bash (linkage is satisfied from bash + when compiling with bash, and internally otherwise) now have an sh_ prefix. + +q. Changed the shared library creation procedure on Linux and BSD/OS 4.x so + that the `soname' contains only the major version number rather than the + major and minor numbers. + +r. Fixed a redisplay bug that occurred when the prompt spanned more than one + physical line and contained invisible characters. + +s. Added a missing `includedir' variable to the Makefile. + +t. When installing the shared libraries, make sure symbolic links are relative. + +u. Added configure test so that it can set `${MAKE}' appropriately. + +v. Fixed a bug in rl_forward that could cause the point to be set to before + the beginning of the line in vi mode. + +w. Fixed a bug in the callback read-char interface to make it work when a + readline function pushes some input onto the input stream with + rl_execute_next (like the incremental search functions). + +x. Fixed a file descriptor leak in the history file manipulation code that + was tripped when attempting to truncate a non-regular file (like + /dev/null). + +y. Changes to make all of the exported readline functions declared in + readline.h have an rl_ prefix (rltty_set_default_bindings is now + rl_tty_set_default_bindings, crlf is now rl_crlf, etc.) + +z. The formatted documentation included in the base readline distribution + is no longer removed on a `make distclean'. + +aa. Some changes were made to avoid gcc warnings with -Wall. + +bb. rl_get_keymap_by_name now finds keymaps case-insensitively, so + `set keymap EMACS' works. + +cc. The history file writing and truncation functions now return a useful + status on error. + +dd. Fixed a bug that could cause applications to dereference a NULL pointer + if a NULL second argument was passed to history_expand(). + +ee. If a hook function assigned to rl_event_hook sets rl_done to a non-zero + value, rl_read_key() now immediately returns '\n' (which is assumed to + be bound to accept-line). + +2. New Features in Readline + +a. The blink timeout for paren matching is now settable by applications, + via the rl_set_paren_blink_timeout() function. + +b. _rl_executing_macro has been renamed to rl_executing_macro, which means + it's now part of the public interface. + +c. Readline has a new variable, rl_readline_state, which is a bitmap that + encapsulates the current state of the library; intended for use by + callbacks and hook functions. + +d. rlfe has a new -l option to log input and output (-a appends to logfile), + a new -n option to set the readline application name, and -v and -h + options for version and help information. + +e. rlfe can now perform filename completion for the inferior process if the + OS has a /proc/<PID>/cwd that can be read with readlink(2) to get the + inferior's current working directory. + +f. A new file, rltypedefs.h, contains the new typedefs for function pointers + and is installed by `make install'. + +g. New application-callable function rl_set_prompt(const char *prompt): + expands its prompt string argument and sets rl_prompt to the result. + +h. New application-callable function rl_set_screen_size(int rows, int cols): + public method for applications to set readline's idea of the screen + dimensions. + +i. The history example program (examples/histexamp.c) is now built as one + of the examples. + +j. The documentation has been updated to cover nearly all of the public + functions and variables declared in readline.h. + +k. New function, rl_get_screen_size (int *rows, int *columns), returns + readline's idea of the screen dimensions. + +l. The timeout in rl_gather_tyi (readline keyboard input polling function) + is now settable via a function (rl_set_keyboard_input_timeout()). + +m. Renamed the max_input_history variable to history_max_entries; the old + variable is maintained for backwards compatibility. + +n. The list of characters that separate words for the history tokenizer is + now settable with a variable: history_word_delimiters. The default + value is as before. + +o.

The GNU +History library is able to keep track of those lines, associate arbitrary +data with each line, and utilize information from previous lines in +composing new ones. +.PP +.SH "HISTORY EXPANSION" +.PP +The history library supports a history expansion feature that +is identical to the history expansion in +.BR bash. +This section describes what syntax features are available. +.PP +History expansions introduce words from the history list into +the input stream, making it easy to repeat commands, insert the +arguments to a previous command into the current input line, or +fix errors in previous commands quickly. +.PP +History expansion is usually performed immediately after a complete line +is read. +It takes place in two parts. +The first is to determine which line from the history list +to use during substitution. +The second is to select portions of that line for inclusion into +the current one. +The line selected from the history is the \fIevent\fP, +and the portions of that line that are acted upon are \fIwords\fP. +Various \fImodifiers\fP are available to manipulate the selected words. +The line is broken into words in the same fashion as \fBbash\fP +does when reading input, +so that several words that would otherwise be separated +are considered one word when surrounded by quotes (see the +description of \fBhistory_tokenize()\fP below). +History expansions are introduced by the appearance of the +history expansion character, which is \^\fB!\fP\^ by default. +Only backslash (\^\fB\e\fP\^) and single quotes can quote +the history expansion character. +.SS Event Designators +.PP +An event designator is a reference to a command line entry in the +history list. +.PP +.PD 0 +.TP +.B ! +Start a history substitution, except when followed by a +.BR blank , +newline, = or (. +.TP +.B !\fIn\fR +Refer to command line +.IR n . +.TP +.B !\-\fIn\fR +Refer to the current command line minus +.IR n . +.TP +.B !! +Refer to the previous command.

For the shell, this is the command +word. +.TP +.I n +The \fIn\fRth word. +.TP +.B ^ +The first argument. That is, word 1. +.TP +.B $ +The last argument. +.TP +.B % +The word matched by the most recent `?\fIstring\fR?' search. +.TP +.I x\fB\-\fPy +A range of words; `\-\fIy\fR' abbreviates `0\-\fIy\fR'. +.TP +.B * +All of the words but the zeroth. This is a synonym +for `\fI1\-$\fP'.

Any delimiter can be used in place of /. The +final delimiter is optional if it is the last character of the +event line. The delimiter may be quoted in +.I old +and +.I new +with a single backslash. If & appears in +.IR new , +it is replaced by +.IR old . +A single backslash will quote the &. If +.I old +is null, it is set to the last +.I old +substituted, or, if no previous history substitutions took place, +the last +.I string +in a +.B !?\fIstring\fR\fB[?]\fR +search. +.TP +.B & +Repeat the previous substitution. +.TP +.B g +Cause changes to be applied over the entire event line. This is +used in conjunction with `\fB:s\fP' (e.g., `\fB:gs/\fIold\fP/\fInew\fP/\fR') +or `\fB:&\fP'. If used with +`\fB:s\fP', any delimiter can be used +in place of /, and the final delimiter is optional +if it is the last character of the event line. +.PD +.SH "PROGRAMMING WITH HISTORY FUNCTIONS" +This section describes how to use the History library in other programs. +.SS Introduction to History +.PP +The programmer using the History library has available functions +for remembering lines on a history list, associating arbitrary data +with a line, removing lines from the list, searching through the list +for a line containing an arbitrary text string, and referencing any line +in the list directly. In addition, a history \fIexpansion\fP function +is available which provides for a consistent user interface across +different programs. +.PP +The user using programs written with the History library has the +benefit of a consistent user interface with a set of well-known +commands for manipulating the text of previous lines and using that text +in new commands. The basic history manipulation commands are +identical to +the history substitution provided by \fBbash\fP. +.PP +If the programmer desires, he can use the Readline library, which +includes some history manipulation by default, and has the added +advantage of command line editing. +.PP +Before declaring any functions using any functionality the History +library provides in other code, an application writer should include +the file +.FN <readline/history.h> +in any file that uses the +History library's features. It supplies extern declarations for all +of the library's public functions and variables, and declares all of +the public data structures. + +.SS History Storage +.PP +The history list is an array of history entries. A history entry is +declared as follows: +.PP +.Vb "typedef void *" histdata_t; +.PP +.nf +typedef struct _hist_entry { + char *line; + histdata_t data; +} HIST_ENTRY; +.fi +.PP +The history list itself might therefore be declared as +.PP +.Vb "HIST_ENTRY **" the_history_list; +.PP +The state of the History library is encapsulated into a single structure: +.PP +.nf +/* + * A structure used to pass around the current state of the history. + */ +typedef struct _hist_state { + HIST_ENTRY **entries; /* Pointer to the entries themselves. */ + int offset; /* The location pointer within this array. */ + int length; /* Number of elements within this array. */ + int size; /* Number of slots allocated to this array. */ + int flags; +} HISTORY_STATE; +.fi +.PP +If the flags member includes \fBHS_STIFLED\fP, the history has been +stifled. +.SH "History Functions" +.PP +This section describes the calling sequence for the various functions +exported by the GNU History library. +.SS Initializing History and State Management +This section describes functions used to initialize and manage +the state of the History library when you want to use the history +functions in your program. + +.Fn1 void using_history void +Begin a session in which the history functions might be used. This +initializes the interactive variables. + +.Fn1 "HISTORY_STATE *" history_get_history_state void +Return a structure describing the current state of the input history. + +.Fn1 void history_set_history_state "HISTORY_STATE *state" +Set the state of the history list according to \fIstate\fP. + +.SS History List Management + +These functions manage individual entries on the history list, or set +parameters managing the list itself. + +.Fn1 void add_history "const char *string" +Place \fIstring\fP at the end of the history list. The associated data +field (if any) is set to \fBNULL\fP. + +.Fn1 "HIST_ENTRY *" remove_history "int which" +Remove history entry at offset \fIwhich\fP from the history. The +removed element is returned so you can free the line, data, +and containing structure. + +.Fn3 "HIST_ENTRY *" replace_history_entry "int which" "const char *line" "histdata_t data" +Make the history entry at offset \fIwhich\fP have \fIline\fP and \fIdata\fP. +This returns the old entry so you can dispose of the data. In the case +of an invalid \fIwhich\fP, a \fBNULL\fP pointer is returned. + +.Fn1 void clear_history "void" +Clear the history list by deleting all the entries. + +.Fn1 void stifle_history "int max" +Stifle the history list, remembering only the last \fImax\fP entries. + +.Fn1 int unstifle_history "void" +Stop stifling the history. This returns the previous amount the +history was stifled. The value is positive if the history was +stifled, negative if it wasn't. + +.Fn1 int history_is_stifled "void" +Returns non-zero if the history is stifled, zero if it is not. + +.SS Information About the History List + +These functions return information about the entire history list or +individual list entries. + +.Fn1 "HIST_ENTRY **" history_list "void" +Return a \fBNULL\fP terminated array of \fIHIST_ENTRY *\fP which is the +current input history. Element 0 of this list is the beginning of time. +If there is no history, return \fBNULL\fP. + +.Fn1 int where_history "void" +Returns the offset of the current history element. + +.Fn1 "HIST_ENTRY *" current_history "void" +Return the history entry at the current position, as determined by +\fBwhere_history()\fP. If there is no entry there, return a \fBNULL\fP +pointer. + +.Fn1 "HIST_ENTRY *" history_get "int offset" +Return the history entry at position \fIoffset\fP, starting from +\fBhistory_base\fP. +If there is no entry there, or if \fIoffset\fP +is greater than the history length, return a \fBNULL\fP pointer. + +.Fn1 int history_total_bytes "void" +Return the number of bytes that the primary history entries are using. +This function returns the sum of the lengths of all the lines in the +history. + +.SS Moving Around the History List + +These functions allow the current index into the history list to be +set or changed. + +.Fn1 int history_set_pos "int pos" +Set the current history offset to \fIpos\fP, an absolute index +into the list. +Returns 1 on success, 0 if \fIpos\fP is less than zero or greater +than the number of history entries. + +.Fn1 "HIST_ENTRY *" previous_history "void" +Back up the current history offset to the previous history entry, and +return a pointer to that entry. If there is no previous entry, return +a \fBNULL\fP pointer. + +.Fn1 "HIST_ENTRY *" next_history "void" +Move the current history offset forward to the next history entry, and +return the a pointer to that entry. If there is no next entry, return +a \fBNULL\fP pointer. + +.SS Searching the History List + +These functions allow searching of the history list for entries containing +a specific string. Searching may be performed both forward and backward +from the current history position. The search may be \fIanchored\fP, +meaning that the string must match at the beginning of the history entry. + +.Fn2 int history_search "const char *string" "int direction" +Search the history for \fIstring\fP, starting at the current history offset. +If \fIdirection\fP is less than 0, then the search is through +previous entries, otherwise through subsequent entries. +If \fIstring\fP is found, then +the current history index is set to that history entry, and the value +returned is the offset in the line of the entry where +\fIstring\fP was found. Otherwise, nothing is changed, and a -1 is +returned. + +.Fn2 int history_search_prefix "const char *string" "int direction" +Search the history for \fIstring\fP, starting at the current history +offset. The search is anchored: matching lines must begin with +\fIstring\fP. If \fIdirection\fP is less than 0, then the search is +through previous entries, otherwise through subsequent entries. +If \fIstring\fP is found, then the +current history index is set to that entry, and the return value is 0. +Otherwise, nothing is changed, and a -1 is returned. + +.Fn3 int history_search_pos "const char *string" "int direction" "int pos" +Search for \fIstring\fP in the history list, starting at \fIpos\fP, an +absolute index into the list. If \fIdirection\fP is negative, the search +proceeds backward from \fIpos\fP, otherwise forward. Returns the absolute +index of the history element where \fIstring\fP was found, or -1 otherwise. + +.SS Managing the History File +The History library can read the history from and write it to a file. +This section documents the functions for managing a history file. + +.Fn1 int read_history "const char *filename" +Add the contents of \fIfilename\fP to the history list, a line at a time. +If \fIfilename\fP is \fBNULL\fP, then read from \fI~/.history\fP. +Returns 0 if successful, or \fBerrno\fP if not. + +.Fn3 int read_history_range "const char *filename" "int from" "int to" +Read a range of lines from \fIfilename\fP, adding them to the history list. +Start reading at line \fIfrom\fP and end at \fIto\fP. +If \fIfrom\fP is zero, start at the beginning. If \fIto\fP is less than +\fIfrom\fP, then read until the end of the file. If \fIfilename\fP is +\fBNULL\fP, then read from \fI~/.history\fP. Returns 0 if successful, +or \fBerrno\fP if not. + +.Fn1 int write_history "const char *filename" +Write the current history to \fIfilename\fP, overwriting \fIfilename\fP +if necessary. +If \fIfilename\fP is \fBNULL\fP, then write the history list to \fI~/.history\fP. +Returns 0 on success, or \fBerrno\fP on a read or write error. + + +.Fn2 int append_history "int nelements" "const char *filename" +Append the last \fInelements\fP of the history list to \fIfilename\fP. +If \fIfilename\fP is \fBNULL\fP, then append to \fI~/.history\fP. +Returns 0 on success, or \fBerrno\fP on a read or write error. + +.Fn2 int history_truncate_file "const char *filename" "int nlines" +Truncate the history file \fIfilename\fP, leaving only the last +\fInlines\fP lines. +If \fIfilename\fP is \fBNULL\fP, then \fI~/.history\fP is truncated. +Returns 0 on success, or \fBerrno\fP on failure. + +.SS History Expansion + +These functions implement history expansion. + +.Fn2 int history_expand "char *string" "char **output" +Expand \fIstring\fP, placing the result into \fIoutput\fP, a pointer +to a string.
