If your program is one of these, then +it can provide completion for commands, data, or both. The following +sections describe how your program and Readline cooperate to provide +this service. + +* Menu: + +* How Completing Works:: The logic used to do completion. +* Completion Functions:: Functions provided by Readline. +* Completion Variables:: Variables which control completion. +* A Short Completion Example:: An example of writing completer subroutines. + + +File: readline.info, Node: How Completing Works, Next: Completion Functions, Up: Custom Completers + +How Completing Works +-------------------- + + In order to complete some text, the full list of possible completions +must be available. That is, it is not possible to accurately expand a +partial word without knowing all of the possible words which make sense +in that context. The Readline library provides the user interface to +completion, and two of the most common completion functions: filename +and username. For completing other types of text, you must write your +own completion function. This section describes exactly what such +functions must do, and provides an example. + + There are three major functions used to perform completion: + + 1. The user-interface function `rl_complete ()'. This function is + called with the same arguments as other Readline functions + intended for interactive use: COUNT and INVOKING_KEY. It + isolates the word to be completed and calls `completion_matches + ()' to generate a list of possible completions. It then either + lists the possible completions, inserts the possible completions, + or actually performs the completion, depending on which behavior + is desired. + + 2. The internal function `completion_matches ()' uses your + "generator" function to generate the list of possible matches, and + then returns the array of these matches. You should place the + address of your generator function in + `rl_completion_entry_function'. + + 3. The generator function is called repeatedly from + `completion_matches ()', returning a string each time. The + arguments to the generator function are TEXT and STATE. TEXT is + the partial word to be completed. STATE is zero the first time + the function is called, allowing the generator to perform any + necessary initialization, and a positive non-zero integer for each + subsequent call. When the generator function returns `(char + *)NULL' this signals `completion_matches ()' that there are no + more possibilities left. Usually the generator function computes + the list of possible completions when STATE is zero, and returns + them one at a time on subsequent calls. Each string the generator + function returns as a match must be allocated with `malloc()'; + Readline frees the strings when it has finished with them. + + + - Function: int rl_complete (int ignore, int invoking_key) + Complete the word at or before point. You have supplied the + function that does the initial simple matching selection algorithm + (see `completion_matches ()'). The default is to do filename + completion. + + - Variable: Function * rl_completion_entry_function + This is a pointer to the generator function for `completion_matches + ()'. If the value of `rl_completion_entry_function' is `(Function + *)NULL' then the default filename generator function, + `filename_entry_function ()', is used. + + +File: readline.info, Node: Completion Functions, Next: Completion Variables, Prev: How Completing Works, Up: Custom Completers + +Completion Functions +-------------------- + + Here is the complete list of callable completion functions present in +Readline. + + - Function: int rl_complete_internal (int what_to_do) + Complete the word at or before point. WHAT_TO_DO says what to do + with the completion. A value of `?' means list the possible + completions. `TAB' means do standard completion. `*' means + insert all of the possible completions. `!' means to display all + of the possible completions, if there is more than one, as well as + performing partial completion. + + - Function: int rl_complete (int ignore, int invoking_key) + Complete the word at or before point. You have supplied the + function that does the initial simple matching selection algorithm + (see `completion_matches ()' and `rl_completion_entry_function'). + The default is to do filename completion. This calls + `rl_complete_internal ()' with an argument depending on + INVOKING_KEY. + + - Function: int rl_possible_completions (int count, int invoking_key)) + List the possible completions. See description of `rl_complete + ()'. This calls `rl_complete_internal ()' with an argument of `?'. + + - Function: int rl_insert_completions (int count, int invoking_key)) + Insert the list of possible completions into the line, deleting the + partially-completed word. See description of `rl_complete ()'. + This calls `rl_complete_internal ()' with an argument of `*'. + + - Function: char ** completion_matches (char *text, CPFunction + *entry_func) + Returns an array of `(char *)' which is a list of completions for + TEXT. If there are no completions, returns `(char **)NULL'. The + first entry in the returned array is the substitution for TEXT. + The remaining entries are the possible completions. The array is + terminated with a `NULL' pointer. + + ENTRY_FUNC is a function of two args, and returns a `(char *)'. + The first argument is TEXT. The second is a state argument; it is + zero on the first call, and non-zero on subsequent calls. + eNTRY_FUNC returns a `NULL' pointer to the caller when there are + no more matches. + + - Function: char * filename_completion_function (char *text, int state) + A generator function for filename completion in the general case. + Note that completion in Bash is a little different because of all + the pathnames that must be followed when looking up completions + for a command. The Bash source is a useful reference for writing + custom completion functions. + + - Function: char * username_completion_function (char *text, int state) + A completion generator for usernames. TEXT contains a partial + username preceded by a random character (usually `~'). As with all + completion generators, STATE is zero on the first call and non-zero + for subsequent calls. + + +File: readline.info, Node: Completion Variables, Next: A Short Completion Example, Prev: Completion Functions, Up: Custom Completers + +Completion Variables +-------------------- + + - Variable: Function * rl_completion_entry_function + A pointer to the generator function for `completion_matches ()'. + `NULL' means to use `filename_entry_function ()', the default + filename completer. + + - Variable: CPPFunction * rl_attempted_completion_function + A pointer to an alternative function to create matches. The + function is called with TEXT, START, and END. START and END are + indices in `rl_line_buffer' saying what the boundaries of TEXT + are. If this function exists and returns `NULL', or if this + variable is set to `NULL', then `rl_complete ()' will call the + value of `rl_completion_entry_function' to generate matches, + otherwise the array of strings returned will be used. + + - Variable: int rl_completion_query_items + Up to this many items will be displayed in response to a + possible-completions call. After that, we ask the user if she is + sure she wants to see them all. The default value is 100. + + - Variable: char * rl_basic_word_break_characters + The basic list of characters that signal a break between words for + the completer routine. The default value of this variable is the + characters which break words for completion in Bash, i.e., `" + \t\n\"\\'`@$><=;|&{("'. + + - Variable: char * rl_completer_word_break_characters + The list of characters that signal a break between words for + `rl_complete_internal ()'. The default list is the value of + `rl_basic_word_break_characters'. + + - Variable: char * rl_special_prefixes + The list of characters that are word break characters, but should + be left in TEXT when it is passed to the completion function. + Programs can use this to help determine what kind of completing to + do. For instance, Bash sets this variable to "$@" so that it can + complete shell variables and hostnames. + + - Variable: int rl_ignore_completion_duplicates + If non-zero, then disallow duplicates in the matches. Default is + 1. + + - Variable: int rl_filename_completion_desired + Non-zero means that the results of the matches are to be treated as + filenames. This is *always* zero on entry, and can only be changed + within a completion entry generator function. If it is set to a + non-zero value, directory names have a slash appended and Readline + attempts to quote completed filenames if they contain any embedded + word break characters. + + - Variable: int rl_filename_quoting_desired + Non-zero means that the results of the matches are to be quoted + using double quotes (or an application-specific quoting mechanism) + if the completed filename contains any characters in + `rl_completer_word_break_chars'. This is *always* non-zero on + entry, and can only be changed within a completion entry generator + function. + + - Variable: Function * rl_ignore_some_completions_function + This function, if defined, is called by the completer when real + filename completion is done, after all the matching names have + been generated. It is passed a `NULL' terminated array of matches. + The first element (`matches[0]') is the maximal substring common + to all matches. This function can re-arrange the list of matches + as required, but each element deleted from the array must be freed. + + - Variable: char * rl_completer_quote_characters + List of characters which can be used to quote a substring of the + line. Completion occurs on the entire substring, and within the + substring `rl_completer_word_break_characters' are treated as any + other character, unless they also appear within this list. + + +File: readline.info, Node: A Short Completion Example, Prev: Completion Variables, Up: Custom Completers + +A Short Completion Example +-------------------------- + + Here is a small application demonstrating the use of the GNU Readline +library.
