NAME Vim::Complete - Generate auto completion information for vim SYNOPSIS my (@dirs, $verbose, $min_length); my $filename = '...'; Vim::Complete->new( dirs => \@dirs, verbose => $verbose, min_length => $min_length, )->parse->report_to_file($filename); DESCRIPTION Vim has a good auto completion mechanism. In insert mode, you can type Control-n to complete on the current string; you can cycle through the possible completions by repeatedly typing Control-n. See ":help complete" in vim for more information. By default, vim completes on identifiers it finds in the current buffer, buffers in other windows, other loaded buffers, unloaded buffers, tags and included files. That means you still have to type the identifier once so vim knows about it. However, you can extend the way vim completes. It can take additional identifiers from a file. So Vim::Complete takes a list of directories - usually @INC -, looks at the modules contained therein, parses package names, variable names and subroutine names and writes them to a file. Now you need to tell vim where to find the file with the Perl identifiers. Put this line into your ".vimrc": set complete+=k~/.vimcomplete The <+=k> tells vim to also look into the specified file. For this to work well, you need to tell vim that colons are part of identifiers in Perl (for example, "Foo::Bar" is an identifier. Put this line in your ".vimrc": set iskeyword+=: Included in this distribution is the program "mk_vim_complete", which is a command-line frontend to Vim::Complete. You can tell Vim::Complete to only use identifiers that are of a certain minimum length. An identifier that is only one character long (such as $x) doesn't need to be completed. If you would include two-character identifiers, you might throw off the auto completion by having to cycle through too many identifiers. So the default minimum length is 3. METHODS "new" my $obj = Vim::Complete->new; my $obj = Vim::Complete->new(%args); Creates and returns a new object. The constructor will accept as arguments a list of pairs, from component name to initial value. For each pair, the named component is initialized by calling the method of the same name with the given value. If called with a single hash reference, it is dereferenced and its key/value pairs are set as described before. "clear_dirs" $obj->clear_dirs; Deletes all elements from the array. "clear_min_length" $obj->clear_min_length; Clears the value. "clear_result" $obj->clear_result; Deletes all keys and values from the hash. "clear_verbose" $obj->clear_verbose; Clears the boolean value by setting it to 0. "count_dirs" my $count = $obj->count_dirs; Returns the number of elements in the array. "delete_result" $obj->delete_result(@keys); Takes a list of keys and deletes those keys from the hash. "dirs" my @values = $obj->dirs; my $array_ref = $obj->dirs; $obj->dirs(@values); $obj->dirs($array_ref); Get or set the array values. If called without an arguments, it returns the array in list context, or a reference to the array in scalar context. If called with arguments, it expands array references found therein and sets the values. "dirs_clear" $obj->dirs_clear; Deletes all elements from the array. "dirs_count" my $count = $obj->dirs_count; Returns the number of elements in the array. "dirs_index" my $element = $obj->dirs_index(3); my @elements = $obj->dirs_index(@indices); my $array_ref = $obj->dirs_index(@indices); Takes a list of indices and returns the elements indicated by those indices. If only one index is given, the corresponding array element is returned. If several indices are given, the result is returned as an array in list context or as an array reference in scalar context. "dirs_pop" my $value = $obj->dirs_pop; Pops the last element off the array, returning it. "dirs_push" $obj->dirs_push(@values); Pushes elements onto the end of the array. "dirs_set" $obj->dirs_set(1 => $x, 5 => $y); Takes a list of index/value pairs and for each pair it sets the array element at the indicated index to the indicated value. Returns the number of elements that have been set. "dirs_shift" my $value = $obj->dirs_shift; Shifts the first element off the array, returning it. "dirs_splice" $obj->dirs_splice(2, 1, $x, $y); $obj->dirs_splice(-1); $obj->dirs_splice(0, -1); Takes three arguments: An offset, a length and a list. Removes the elements designated by the offset and the length from the array, and replaces them with the elements of the list, if any. In list context, returns the elements removed from the array. In scalar context, returns the last element removed, or "undef" if no elements are removed. The array grows or shrinks as necessary. If the offset is negative then it starts that far from the end of the array. If the length is omitted, removes everything from the offset onward. If the length is negative, removes the elements from the offset onward except for -length elements at the end of the array. If both the offset and the length are omitted, removes everything. If the offset is past the end of the array, it issues a warning, and splices at the end of the array. "dirs_unshift" $obj->dirs_unshift(@values); Unshifts elements onto the beginning of the array. "exists_result" if ($obj->exists_result($key)) { ... } Takes a key and returns a true value if the key exists in the hash, and a false value otherwise. "index_dirs" my $element = $obj->index_dirs(3); my @elements = $obj->index_dirs(@indices); my $array_ref = $obj->index_dirs(@indices); Takes a list of indices and returns the elements indicated by those indices. If only one index is given, the corresponding array element is returned. If several indices are given, the result is returned as an array in list context or as an array reference in scalar context. "keys_result" my @keys = $obj->keys_result; Returns a list of all hash keys in no particular order. "min_length" my $value = $obj->min_length; $obj->min_length($value); A basic getter/setter method. If called without an argument, it returns the value. If called with a single argument, it sets the value. "min_length_clear" $obj->min_length_clear; Clears the value. "pop_dirs" my $value = $obj->pop_dirs; Pops the last element off the array, returning it. "push_dirs" $obj->push_dirs(@values); Pushes elements onto the end of the array. "result" my %hash = $obj->result; my $hash_ref = $obj->result; my $value = $obj->result($key); my @values = $obj->result([ qw(foo bar) ]); $obj->result(%other_hash); $obj->result(foo => 23, bar => 42); Get or set the hash values. If called without arguments, it returns the hash in list context, or a reference to the hash in scalar context. If called with a list of key/value pairs, it sets each key to its corresponding value, then returns the hash as described before. If called with exactly one key, it returns the corresponding value. If called with exactly one array reference, it returns an array whose elements are the values corresponding to the keys in the argument array, in the same order. The resulting list is returned as an array in list context, or a reference to the array in scalar context. If called with exactly one hash reference, it updates the hash with the given key/value pairs, then returns the hash in list context, or a reference to the hash in scalar context. "result_clear" $obj->result_clear; Deletes all keys and values from the hash. "result_delete" $obj->result_delete(@keys); Takes a list of keys and deletes those keys from the hash. "result_exists" if ($obj->result_exists($key)) { ... } Takes a key and returns a true value if the key exists in the hash, and a false value otherwise. "result_keys" my @keys = $obj->result_keys; Returns a list of all hash keys in no particular order. "result_values" my @values = $obj->result_values; Returns a list of all hash values in no particular order. "set_dirs" $obj->set_dirs(1 => $x, 5 => $y); Takes a list of index/value pairs and for each pair it sets the array element at the indicated index to the indicated value. Returns the number of elements that have been set. "set_verbose" $obj->set_verbose; Sets the boolean value to 1. "shift_dirs" my $value = $obj->shift_dirs; Shifts the first element off the array, returning it. "splice_dirs" $obj->splice_dirs(2, 1, $x, $y); $obj->splice_dirs(-1); $obj->splice_dirs(0, -1); Takes three arguments: An offset, a length and a list. Removes the elements designated by the offset and the length from the array, and replaces them with the elements of the list, if any. In list context, returns the elements removed from the array. In scalar context, returns the last element removed, or "undef" if no elements are removed. The array grows or shrinks as necessary. If the offset is negative then it starts that far from the end of the array. If the length is omitted, removes everything from the offset onward. If the length is negative, removes the elements from the offset onward except for -length elements at the end of the array. If both the offset and the length are omitted, removes everything. If the offset is past the end of the array, it issues a warning, and splices at the end of the array. "unshift_dirs" $obj->unshift_dirs(@values); Unshifts elements onto the beginning of the array. "values_result" my @values = $obj->values_result; Returns a list of all hash values in no particular order. "verbose" $obj->verbose($value); my $value = $obj->verbose; If called without an argument, returns the boolean value (0 or 1). If called with an argument, it normalizes it to the boolean value. That is, the values 0, undef and the empty string become 0; everything else becomes 1. "verbose_clear" $obj->verbose_clear; Clears the boolean value by setting it to 0. "verbose_set" $obj->verbose_set; Sets the boolean value to 1. "parse" Assumes that "dir()", and optionally "verbose()" and "min_length()", have been set and starts to look in the directories for files ending in ".pm". For each file it gathers information using "gather()". Returns the Vim::Complete object so method calls can be chained as seen in the "SYNOPSIS". "report" Takes all the gathered findings and returns the list of identifiers. Returns an array in list context, or a reference to the array in scalar context. "report_to_file" Takes as argument a filename. Writes the report generated by "report()" to the file. "gather" Takes a filename of a module, parses the source code and makes a note of the package names, subroutine names and variable names it sees. This method is called by "parse()"; it is unlikely that you want to call it yourself. Vim::Complete inherits from Class::Accessor::Complex.
