| History Expansion |
| ================= |
| |
| The History library provides a history expansion feature that is |
| similar to the history expansion provided by `csh'. This section |
| describes the syntax used to manipulate the history information. |
| |
| 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. |
| |
| History expansion takes place in two parts. The first is to |
| determine which line from the history list should be used during |
| substitution. The second is to select portions of that line for |
| inclusion into the current one. The line selected from the history is |
| called the "event", and the portions of that line that are acted upon |
| are called "words". Various "modifiers" are available to manipulate |
| the selected words. The line is broken into words in the same fashion |
| that Bash does, so that several words surrounded by quotes are |
| considered one word. History expansions are introduced by the |
| appearance of the history expansion character, which is `!' by default. |

| |
| Event Designators |
| ----------------- |
| |
| An event designator is a reference to a command line entry in the |
| history list. |
| |
| `!' |
| Start a history substitution, except when followed by a space, tab, |
| the end of the line, `=' or `('. |
| |
| `!N' |
| Refer to command line N. |
| |
| `!-N' |
| Refer to the command N lines back. |
| |
| `!!' |
| Refer to the previous command. This is a synonym for `!-1'. |
| |
| `!STRING' |
| Refer to the most recent command starting with STRING. |
| |
| `!?STRING[?]' |
| Refer to the most recent command containing STRING. The trailing |
| `?' may be omitted if the STRING is followed immediately by a |
| newline. |
| |
| `^STRING1^STRING2^' |
| Quick Substitution. Repeat the last command, replacing STRING1 |
| with STRING2. Equivalent to `!!:s/STRING1/STRING2/'. |
| |
| `!#' |
| The entire command line typed so far. |
| |
| |
| File: history.info, Node: Word Designators, Next: Modifiers, Prev: Event Designators, Up: History Interaction |
| |
| Word Designators |
| ---------------- |
| |
| Word designators are used to select desired words from the event. A |
| `:' separates the event specification from the word designator. It may |
| be omitted if the word designator begins with a `^', `$', `*', `-', or |
| `%'. Words are numbered from the beginning of the line, with the first |
| word being denoted by 0 (zero). Words are inserted into the current |
| line separated by single spaces. |
| |
| For example, |
| |
| `!!' |
| designates the preceding command. When you type this, the |
| preceding command is repeated in toto. |
| |
| `!!:$' |
| designates the last argument of the preceding command. This may be |
| shortened to `!$'. |
| |
| `!fi:2' |
| designates the second argument of the most recent command starting |
| with the letters `fi'. |
| |
| Here are the word designators: |
| |
| `0 (zero)' |
| The `0'th word. For many applications, this is the command word. |
| |
| `N' |
| The Nth word. |
| |
| `^' |
| The first argument; that is, word 1. |
| |
| `$' |
| The last argument. |
| |
| `%' |
| The word matched by the most recent `?STRING?' search. |
| |
| `X-Y' |
| A range of words; `-Y' abbreviates `0-Y'. |
| |
| `*' |
| All of the words, except the `0'th. This is a synonym for `1-$'. |
| It is not an error to use `*' if there is just one word in the |
| event; the empty string is returned in that case. |
| |
| `X*' |
| Abbreviates `X-$' |
| |
| `X-' |
| Abbreviates `X-$' like `X*', but omits the last word. |
| |
| If a word designator is supplied without an event specification, the |
| previous command is used as the event. |
| |
| |
| File: history.info, Node: Modifiers, Prev: Word Designators, Up: History Interaction |
| |
| Modifiers |
| --------- |
| |
| After the optional word designator, you can add a sequence of one or |
| more of the following modifiers, each preceded by a `:'. |
| |
| `h' |
| Remove a trailing pathname component, leaving only the head. |
| |
| `t' |
| Remove all leading pathname components, leaving the tail. |
| |
| `r' |
| Remove a trailing suffix of the form `.SUFFIX', leaving the |
| basename. |
| |
| `e' |
| Remove all but the trailing suffix. |
| |
| `p' |
| Print the new command but do not execute it. |
| |
| `s/OLD/NEW/' |
| Substitute NEW for the first occurrence of OLD in the event line. |
| Any delimiter may be used in place of `/'. The delimiter may be |
| quoted in OLD and NEW with a single backslash. If `&' appears in |
| NEW, it is replaced by OLD. A single backslash will quote the |
| `&'. The final delimiter is optional if it is the last character |
| on the input line. |
| |
| `&' |
| Repeat the previous substitution. |
| |
| `g' |
| Cause changes to be applied over the entire event line. Used in |
| conjunction with `s', as in `gs/OLD/NEW/', or with `&'. |

| Introduction to History |
| ======================= |
| |
| Many programs read input from the user a line at a time. 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. |
| |
| 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 "expansion" function is |
| available which provides for a consistent user interface across |
| different programs. |
| |
| 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 similar to |
| the history substitution provided by `csh'. |
| |
| 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. |
| |
| Before declaring any functions using any functionality the History |
| library provides in other code, an application writer should include |
| the file `<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. |
| |
| |
| File: history.info, Node: History Storage, Next: History Functions, Prev: Introduction to History, Up: Programming with GNU History |
| |
| History Storage |
| =============== |
| |
| The history list is an array of history entries. A history entry is |
| declared as follows: |
| |
| typedef void *histdata_t; |
| |
| typedef struct _hist_entry { |
| char *line; |
| histdata_t data; |
| } HIST_ENTRY; |
| |
| The history list itself might therefore be declared as |
| |
| HIST_ENTRY **the_history_list; |
| |
| The state of the History library is encapsulated into a single |
| structure: |
| |
| /* |
| * 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; |
| |
| If the flags member includes `HS_STIFLED', the history has been |
| stifled. |

| 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. |
| |
| - Function: void using_history (void) |
| Begin a session in which the history functions might be used. This |
| initializes the interactive variables. |
| |
| - Function: HISTORY_STATE * history_get_history_state (void) |
| Return a structure describing the current state of the input |
| history. |
| |
| - Function: void history_set_history_state (HISTORY_STATE *state) |

| |
| History List Management |
| ----------------------- |
| |
| These functions manage individual entries on the history list, or set |
| parameters managing the list itself. |

| - Function: HIST_ENTRY * remove_history (int which) |
| Remove history entry at offset WHICH from the history. The |
| removed element is returned so you can free the line, data, and |
| containing structure. |
| |
| - Function: HIST_ENTRY * replace_history_entry (int which, const char |
| *line, histdata_t data) |
| Make the history entry at offset WHICH have LINE and DATA. This |
| returns the old entry so you can dispose of the data. In the case |
| of an invalid WHICH, a `NULL' pointer is returned. |
| |
| - Function: void clear_history (void) |
| Clear the history list by deleting all the entries. |
| |
| - Function: void stifle_history (int max) |
| Stifle the history list, remembering only the last MAX entries. |
| |
| - Function: int unstifle_history (void) |
| Stop stifling the history. This returns the previously-set |
| maximum number of history entries (as set by `stifle_history()'). |
| The value is positive if the history was stifled, negative if it |
| wasn't. |
| |
| - Function: int history_is_stifled (void) |
| Returns non-zero if the history is stifled, zero if it is not. |
| |
| |
| File: history.info, Node: Information About the History List, Next: Moving Around the History List, Prev: History List Management, Up: History Functions |
| |
| Information About the History List |
| ---------------------------------- |
| |
| These functions return information about the entire history list or |
| individual list entries. |
| |
| - Function: HIST_ENTRY ** history_list (void) |
| Return a `NULL' terminated array of `HIST_ENTRY *' which is the |
| current input history. Element 0 of this list is the beginning of |
| time. If there is no history, return `NULL'. |
| |
| - Function: int where_history (void) |
| Returns the offset of the current history element. |
| |
| - Function: HIST_ENTRY * current_history (void) |
| Return the history entry at the current position, as determined by |
| `where_history()'. If there is no entry there, return a `NULL' |
| pointer. |
| |
| - Function: HIST_ENTRY * history_get (int offset) |
| Return the history entry at position OFFSET, starting from |
| `history_base' (*note History Variables::). If there is no entry |
| there, or if OFFSET is greater than the history length, return a |
| `NULL' pointer. |
| |
| - Function: 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. |

| |
| Moving Around the History List |
| ------------------------------ |
| |
| These functions allow the current index into the history list to be |
| set or changed. |
| |
| - Function: int history_set_pos (int pos) |
| Set the current history offset to POS, an absolute index into the |
| list. Returns 1 on success, 0 if POS is less than zero or greater |
| than the number of history entries. |
| |
| - Function: 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 `NULL' pointer. |
| |
| - Function: 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 `NULL' pointer. |
| |
| |
| File: history.info, Node: Searching the History List, Next: Managing the History File, Prev: Moving Around the History List, Up: History Functions |
| |
| 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 |
| "anchored", meaning that the string must match at the beginning of the |
| history entry. |
| |
| - Function: int history_search (const char *string, int direction) |
| Search the history for STRING, starting at the current history |
| offset. If DIRECTION is less than 0, then the search is through |
| previous entries, otherwise through subsequent entries. If STRING |
| 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 STRING was found. Otherwise, nothing is changed, and |
| a -1 is returned. |
| |
| - Function: int history_search_prefix (const char *string, int |
| direction) |
| Search the history for STRING, starting at the current history |
| offset. The search is anchored: matching lines must begin with |
| STRING. If DIRECTION is less than 0, then the search is through |
| previous entries, otherwise through subsequent entries. If STRING |
| 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. |
| |
| - Function: int history_search_pos (const char *string, int direction, |
| int pos) |
| Search for STRING in the history list, starting at POS, an |
| absolute index into the list. If DIRECTION is negative, the search |
| proceeds backward from POS, otherwise forward. Returns the |
| absolute index of the history element where STRING was found, or |
| -1 otherwise. |

| |
| 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. |
| |
| - Function: int read_history (const char *filename) |
| Add the contents of FILENAME to the history list, a line at a time. |
| If FILENAME is `NULL', then read from `~/.history'. Returns 0 if |
| successful, or `errno' if not. |
| |
| - Function: int read_history_range (const char *filename, int from, |
| int to) |
| Read a range of lines from FILENAME, adding them to the history |
| list. Start reading at line FROM and end at TO. If FROM is zero, |
| start at the beginning. If TO is less than FROM, then read until |
| the end of the file. If FILENAME is `NULL', then read from |
| `~/.history'. Returns 0 if successful, or `errno' if not. |
| |
| - Function: int write_history (const char *filename) |
| Write the current history to FILENAME, overwriting FILENAME if |
| necessary. If FILENAME is `NULL', then write the history list to |
| `~/.history'. Returns 0 on success, or `errno' on a read or write |
| error. |
| |
| - Function: int append_history (int nelements, const char *filename) |
| Append the last NELEMENTS of the history list to FILENAME. If |
| FILENAME is `NULL', then append to `~/.history'. Returns 0 on |
| success, or `errno' on a read or write error. |
| |
| - Function: int history_truncate_file (const char *filename, int |
| nlines) |
| Truncate the history file FILENAME, leaving only the last NLINES |
| lines. If FILENAME is `NULL', then `~/.history' is truncated. |
| Returns 0 on success, or `errno' on failure. |
| |
| |
| File: history.info, Node: History Expansion, Prev: Managing the History File, Up: History Functions |
| |
| History Expansion |
| ----------------- |
| |
| These functions implement history expansion. |
| |
| - Function: int history_expand (char *string, char **output) |
| Expand STRING, placing the result into OUTPUT, a pointer to a |
| string (*note History Interaction::). Returns: |
| `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); |
| |
| `1' |
| if expansions did take place; |
| |
| `-1' |
| if there was an error in expansion; |
| |
| `2' |
| if the returned line should be displayed, but not executed, |
| as with the `:p' modifier (*note Modifiers::). |
| |
| If an error ocurred in expansion, then OUTPUT contains a |
| descriptive error message. |
| |
| - Function: char * get_history_event (const char *string, int *cindex, |
| int qchar) |
| Returns the text of the history event beginning at STRING + |
| *CINDEX. *CINDEX is modified to point to after the event |
| specifier. At function entry, CINDEX points to the index into |
| STRING where the history event specification begins. QCHAR is a |
| character that is allowed to end the event specification in |
| addition to the "normal" terminating characters. |
| |
| - Function: char ** history_tokenize (const char *string) |
| Return an array of tokens parsed out of STRING, much as the shell |
| might. The tokens are split on the characters in the |
| HISTORY_WORD_DELIMITERS variable, and shell quoting conventions |
| are obeyed. |
| |
| - Function: char * history_arg_extract (int first, int last, const |
| char *string) |
| Extract a string segment consisting of the FIRST through LAST |
| arguments present in STRING. Arguments are split using |
| `history_tokenize'. |

| History Variables |
| ================= |
| |
| This section describes the externally-visible variables exported by |
| the GNU History Library. |
| |
| - Variable: int history_base |
| The logical offset of the first entry in the history list. |
| |
| - Variable: int history_length |
| The number of entries currently stored in the history list. |
| |
| - Variable: int history_max_entries |
| The maximum number of history entries. This must be changed using |
| `stifle_history()'. |
| |
| - Variable: char history_expansion_char |
| The character that introduces a history event. The default is `!'. |
| Setting this to 0 inhibits history expansion. |
| |
| - Variable: char history_subst_char |
| The character that invokes word substitution if found at the start |
| of a line. The default is `^'. |
| |
| - Variable: char history_comment_char |
| During tokenization, if this character is seen as the first |
| character of a word, then it and all subsequent characters up to a |
| newline are ignored, suppressing history expansion for the |
| remainder of the line. This is disabled by default. |
| |
| - Variable: char * history_word_delimiters |
| The characters that separate tokens for `history_tokenize()'. The |
| default value is `" \t\n()<>;&|"'. |
| |
| - Variable: char * history_no_expand_chars |
| The list of characters which inhibit history expansion if found |
| immediately following HISTORY_EXPANSION_CHAR. The default is |
| space, tab, newline, carriage return, and `='. |
| |
| - Variable: char * history_search_delimiter_chars |
| The list of additional characters which can delimit a history |
| search string, in addition to space, TAB, `:' and `?' in the case |
| of a substring search. The default is empty. |
| |
| - Variable: int history_quotes_inhibit_expansion |
| If non-zero, single-quoted words are not scanned for the history |
| expansion character. The default value is 0. |
| |
| - Variable: rl_linebuf_func_t * history_inhibit_expansion_function |
| This should be set to the address of a function that takes two |
| arguments: a `char *' (STRING) and an `int' index into that string |
| (I). It should return a non-zero value if the history expansion |
| starting at STRING[I] should not be performed; zero if the |
| expansion should be done. It is intended for use by applications |
| like Bash that use the history expansion character for additional |
| purposes. By default, this variable is set to `NULL'. |
