Changes to Readline + +a. Fixed output of comment-begin character when listing variable values. + +b. Added some default key bindings for common escape sequences produced by + HOME and END keys. + +c. Fixed the mark handling code to be more emacs-compatible. + +d. A bug was fixed in the code that prints possible completions to keep it + from printing empty strings in certain circumstances. + +e. Change the key sequence printing code to print ESC as M\- if ESC is a + meta-prefix character -- it's easier for users to understand than \e. + +f. Fixed unstifle_history() to return values that match the documentation. + +g. Fixed the event loop (rl_event_hook) to handle the case where the input + file descriptor is invalidated. + +h. Fixed the prompt display code to work better when the application has a + custom redisplay function. + +i. Changes to make reading and writing the history file a little faster, and + to cope with huge history files without calling abort(3) from xmalloc. + +j. The vi-mode `S' and `s' commands are now undone correctly. + +k. Fixed a problem which caused the display to be messed up when the last + line of a multi-line prompt (possibly containing invisible characters) + was longer than the screen width. + +2. New Features in Readline + +a. Support for key `subsequences': allows, e.g., ESC and ESC-a to both + be bound to readline functions. Now the arrow keys may be used in vi + insert mode. + +b. When listing completions, and the number of lines displayed is more than + the screen length, readline uses an internal pager to display the results. + This is controlled by the `page-completions' variable (default on). + +c. New code to handle editing and displaying multibyte characters. + +d. The behavior introduced in bash-2.05a of deciding whether or not to + append a slash to a completed name that is a symlink to a directory has + been made optional, controlled by the `mark-symlinked-directories' + variable (default is the 2.05a behavior). + +e. The `insert-comment' command now acts as a toggle if given a numeric + argument: if the first characters on the line don't specify a + comment, insert one; if they do, delete the comment text + +f. New application-settable completion variable: + rl_completion_mark_symlink_dirs, allows an application's completion + function to temporarily override the user's preference for appending + slashes to names which are symlinks to directories. + +g. New function available to application completion functions: + rl_completion_mode, to tell how the completion function was invoked + and decide which argument to supply to rl_complete_internal (to list + completions, etc.). + +h. Readline now has an overwrite mode, toggled by the `overwrite-mode' + bindable command, which could be bound to `Insert'. + +i. New application-settable completion variable: + rl_completion_suppress_append, inhibits appending of + rl_completion_append_character to completed words. + +j. New key bindings when reading an incremental search string: ^W yanks + the currently-matched word out of the current line into the search + string; ^Y yanks the rest of the current line into the search string, + DEL or ^H deletes characters from the search string. + +------------------------------------------------------------------------------- +This document details the changes between this version, readline-4.2a, +and the previous version, readline-4.2. + +1. Changes to Readline + +a. More `const' and type casting fixes. + +b. Changed rl_message() to use vsnprintf(3) (if available) to fix buffer + overflow problems. + +c. The completion code no longer appends a `/' or ` ' to a match when + completing a symbolic link that resolves to a directory name, unless + the match does not add anything to the word being completed. This + means that a tab will complete the word up to the full name, but not + add anything, and a subsequent tab will add a slash. + +d. Fixed a trivial typo that made the vi-mode `dT' command not work. + +e. Fixed the tty code so that ^S and ^Q can be inserted with rl_quoted_insert. + +f. Fixed the tty code so that ^V works more than once. + +g. Changed the use of __P((...)) for function prototypes to PARAMS((...)) + because the use of __P in typedefs conflicted g++ and glibc. + +h. The completion code now attempts to do a better job of preserving the + case of the word the user typed if ignoring case in completions. + +i. Readline defaults to not echoing the input and lets the terminal + initialization code enable echoing if there is a controlling terminal. + +j. The key binding code now processes only two hex digits after a `\x' + escape sequence, and the documentation was changed to note that the + octal and hex escape sequences result in an eight-bit value rather + than strict ASCII. + +k. Fixed a few places where negative array subscripts could have occurred. + +l. Fixed the vi-mode code to use a better method to determine the bounds of + the array used to hold the marks, and to avoid out-of-bounds references. + +m. Fixed the defines in chardefs.h to work better when chars are signed. + +n. Fixed configure.in to use the new names for bash autoconf macros. + +o. Readline no longer attempts to define its own versions of some ctype + macros if they are implemented as functions in libc but not as macros in + <ctype.h>. + +p. Fixed a problem where rl_backward could possibly set point to before + the beginning of the line. + +q. Fixed Makefile to not put -I/usr/include into CFLAGS, since it can cause + include file problems. + +2. New Features in Readline + +a. Added extern declaration for rl_get_termcap to readline.h, making it a + public function (it was always there, just not in readline.h). + +b. New #defines in readline.h: RL_READLINE_VERSION, currently 0x0402, + RL_VERSION_MAJOR, currently 4, and RL_VERSION_MINOR, currently 2. + +c. New readline variable: rl_readline_version, mirrors RL_READLINE_VERSION. + +d. New bindable boolean readline variable: match-hidden-files. Controls + completion of files beginning with a `.' (on Unix). Enabled by default. + +e. The history expansion code now allows any character to terminate a + `:first-' modifier, like csh. + +f. The incremental search code remembers the last search string and uses + it if ^R^R is typed without a search string. + +h. New bindable variable `history-preserve-point'. If set, the history + code attempts to place the user at the same location on each history + line retrived with previous-history or next-history. + +------------------------------------------------------------------------------- +This document details the changes between this version, readline-4.2, +and the previous version, readline-4.1. + +1. 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. There is a new history.3 manual page documenting the history library. + +------------------------------------------------------------------------------- This document details the changes between this version, readline-4.1, and the previous version, readline-4.0. diff --git a/readline/ChangeLog.gdb b/readline/ChangeLog.gdb index 403d870d66c..c970a44ef43 100644 --- a/readline/ChangeLog.gdb +++ b/readline/ChangeLog.gdb @@ -1,3 +1,32 @@ +2002-12-06 Elena Zannoni <ezannoni@redhat.com> + + Import of readline 4.3: + + * compat.c, mbutil.c, misc.c, rlmbutil.h, rltypedefs.h, + text.c, doc/history.0, doc/history.3, support/wcwidth.c, + examples/readlinebuf.h, examples/rlcat.c: New files. + + * CHANGELOG, CHANGES, INSTALL, MANIFEST, Makefile.in, README, + aclocal.m4, ansi_stdlib.h, bind.c, callback.c, chardefs.h, + complete.c, config.h.in, configure, configure.in, display.c, + emacs_keymap.c, funmap.c, histexpand.c, histfile.c, histlib.h, + history.c, history.h, histsearch.c, input.c, isearch.c, + keymaps.c, keymaps.h, kill.c, macro.c, nls.c, parens.c, + posixdir.h, readline.c, readline.h, rlconf.h, rldefs.h, + rlprivate.h, rlshell.h, rlstdc.h, rltty.c, savestring.c, + search.c, shell.c, signals.c, terminal.c, tilde.c, tilde.h, + undo.c, util.c, vi_keymap.c, vi_mode.c, xmalloc.c, xmalloc.h, + doc/Makefile.in, doc/hist.texinfo, doc/hstech.texinfo, + doc/hsuser.texinfo, doc/manvers.texinfo, doc/readline.3, + doc/rlman.texinfo, doc/rltech.texinfo, doc/rluser.texinfo + doc/rluserman.texinfo, doc/texi2dvi, doc/texi2html, + shlib/Makefile.in, support/install.sh, support/mkdirs, + support/mkdist, support/shlib-install, support/shobj-conf, + examples/Inputrc, examples/Makefile.in, examples/fileman.c, + examples/histexamp.c, examples/manexamp.c, examples/rl.c, + examples/rlfe.c, examples/rltest.c, examples/rlversion.c: + Modified files. + 2002-08-23 Andrew Cagney <ac131313@redhat.com> * support/config.guess: Import version 2002-08-23. diff --git a/readline/INSTALL b/readline/INSTALL index 95d84c820fb..adb27a9f222 100644 --- a/readline/INSTALL +++ b/readline/INSTALL @@ -1,73 +1,81 @@ Basic Installation ================== - These are generic installation instructions. - - The `configure' shell script attempts to guess correct values for -various system-dependent variables used during compilation.

If you +try to build shared libraries on an unsupported platform, `make' +will display a message asking you to update support/shobj-conf for +your platform. + +If you need to update support/shobj-conf, you will need to create +a `stanza' for your operating system and compiler. The script uses +the value of host_os and ${CC} as determined by configure.

Many systems use the -R option to the link + editor to embed a path within the library for run-time + library searches. A reasonable value for such systems would + be `-R$(libdir)'. + +SHLIB_LIBS Any additional libraries that shared libraries should be + linked against when they are created. + +SHLIB_LIBSUFF The suffix to add to `libreadline' and `libhistory' when + generating the filename of the shared library. Many systems + use `so'; HP-UX uses `sl'. + +SHLIB_LIBVERSION The string to append to the filename to indicate the version + of the shared library. It should begin with $(SHLIB_LIBSUFF), + and possibly include version information that allows the + run-time loader to load the version of the shared library + appropriate for a particular program. Systems using shared + libraries similar to SunOS 4.x use major and minor library + version numbers; for those systems a value of + `$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)$(SHLIB_MINOR)' is appropriate. + Systems based on System V Release 4 don't use minor version + numbers; use `$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)' on those systems. + Other Unix versions use different schemes. + +SHLIB_STATUS Set this to `supported' when you have defined the other + necessary variables.

This + section describes what syntax features are available. + + 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 cur- + rent input line, or fix errors in previous commands + quickly. + + 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 _e_v_e_n_t, and the portions + of that line that are acted upon are _w_o_r_d_s. Various _m_o_d_i_- + _f_i_e_r_s are available to manipulate the selected words. The + line is broken into words in the same fashion as bbaasshh does + when reading input, so that several words that would oth- + erwise be separated are considered one word when sur- + rounded by quotes (see the description of hhiissttoorryy__ttookk-- + eenniizzee(()) below).

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.

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.

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 previously-set +maximum number of history entries (as set by \fBstifle_history()\fP). +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. Returns: +.RS +.PD 0 +.TP +0 +If no expansions took place (or, if the only change in +the text was the removal of escape characters preceding the history expansion +character); +.TP +1 +if expansions did take place; +.TP +-1 +if there was an error in expansion; +.TP +2 +if the returned line should be displayed, but not executed, +as with the \fB:p\fP modifier. +.PD +.RE +If an error ocurred in expansion, then \fIoutput\fP contains a descriptive +error message. + +.Fn3 "char *" get_history_event "const char *string" "int *cindex" "int qchar" +Returns the text of the history event beginning at \fIstring\fP + +\fI*cindex\fP. \fI*cindex\fP is modified to point to after the event +specifier. At function entry, \fIcindex\fP points to the index into +\fIstring\fP where the history event specification begins. \fIqchar\fP +is a character that is allowed to end the event specification in addition +to the ``normal'' terminating characters. + +.Fn1 "char **" history_tokenize "const char *string" +Return an array of tokens parsed out of \fIstring\fP, much as the +shell might. +The tokens are split on the characters in the +\fBhistory_word_delimiters\fP variable, +and shell quoting conventions are obeyed. + +.Fn3 "char *" history_arg_extract "int first" "int last" "const char *string" +Extract a string segment consisting of the \fIfirst\fP through \fIlast\fP +arguments present in \fIstring\fP.
