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 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. This is a synonym for `!\-1'. -.TP -.B !\fIstring\fR -Refer to the most recent command starting with -.IR string . -.TP -.B !?\fIstring\fR\fB[?]\fR -Refer to the most recent command containing -.IR string . -The trailing \fB?\fP may be omitted if -.I string -is followed immediately by a newline. -.TP -.B \d\s+2^\s-2\u\fIstring1\fP\d\s+2^\s-2\u\fIstring2\fP\d\s+2^\s-2\u -Quick substitution. Repeat the last command, replacing -.I string1 -with -.IR string2 . -Equivalent to -``!!:s/\fIstring1\fP/\fIstring2\fP/'' -(see \fBModifiers\fP below). -.TP -.B !# -The entire command line typed so far. -.PD -.SS Word Designators -.PP -Word designators are used to select desired words from the event. -A -.B : -separates the event specification from the word designator. -It may be omitted if the word designator begins with a -.BR ^ , -.BR $ , -.BR * , -.BR \- , -or -.BR % . -Words are numbered from the beginning of the line, -with the first word being denoted by 0 (zero). -Words are inserted into the current line separated by single spaces. -.PP -.PD 0 -.TP -.B 0 (zero) -The zeroth word. 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\-$\fP'. It is not an error to use -.B * -if there is just one -word in the event; the empty string is returned in that case. -.TP -.B x* -Abbreviates \fIx\-$\fP. -.TP -.B x\- -Abbreviates \fIx\-$\fP like \fBx*\fP, but omits the last word. -.PD -.PP -If a word designator is supplied without an event specification, the -previous command is used as the event. -.SS Modifiers -.PP -After the optional word designator, there may appear a sequence of -one or more of the following modifiers, each preceded by a `:'. -.PP -.PD 0 -.PP -.TP -.B h -Remove a trailing file name component, leaving only the head. -.TP -.B t -Remove all leading file name components, leaving the tail. -.TP -.B r -Remove a trailing suffix of the form \fI.xxx\fP, leaving the -basename. -.TP -.B e -Remove all but the trailing suffix. -.TP -.B p -Print the new command but do not execute it. -.TP -.B q -Quote the substituted words, escaping further substitutions. -.TP -.B x -Quote the substituted words as with -.BR q , -but break into words at -.B blanks -and newlines. -.TP -.B s/\fIold\fP/\fInew\fP/ -Substitute -.I new -for the first occurrence of -.I old -in the event line. 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 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.

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.

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.
