GNU Info (history.info)History VariablesHistory 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'. automatically generated by info2www version 1.2.2.9 |
