NAME

Complete::Util - General completion routine

VERSION

This document describes version 0.41 of Complete::Util (from Perl distribution Complete-Util), released on 2015-11-29.

DESCRIPTION

FUNCTIONS

arrayify_answer(%args) -> array

Make sure we return completion answer in array form.

This is the reverse of hashify_answer. It accepts a hash or an array. If it receives a hash, will return its words key.

This function is not exported by default, but exportable.

Arguments ('*' denotes required arguments):

• arg* => array|hash

Return value: (array)

combine_answers($answers, ...) -> hash

Given two or more answers, combine them into one.

This function is useful if you want to provide a completion answer that is gathered from multiple sources. For example, say you are providing completion for the Perl tool cpanm, which accepts a filename (a tarball like *.tar.gz), a directory, or a module name. You can do something like this:

 combine_answers(
     complete_file(word=>$word, ci=>1),
     complete_module(word=>$word, ci=>1),
 );

If a completion answer has a metadata final set to true, then that answer is used as the final answer without any combining with the other answers.

This function is not exported by default, but exportable.

Arguments ('*' denotes required arguments):

• answers* => array[hash|array]

Return value: (hash)

Return a combined completion answer. Words from each input answer will be combined, order preserved and duplicates removed. The other keys from each answer will be merged.

complete_array_elem(%args) -> array

Complete from array.

Will sort the resulting completion list, so you don't have to presort the array.

This function is not exported by default, but exportable.

Arguments ('*' denotes required arguments):

• array* => array[str]

• exclude => array

• word* => str (default: "")

  Word to complete.

Return value: (array)

complete_hash_key(%args) -> array

Complete from hash keys.

This function is not exported by default, but exportable.

Arguments ('*' denotes required arguments):

• hash* => hash

• word* => str (default: "")

  Word to complete.

Return value: (array)

hashify_answer(%args) -> hash

Make sure we return completion answer in hash form.

This function accepts a hash or an array. If it receives an array, will convert the array into `{words=>$ary}' first to make sure the completion answer is in hash form.

Then will add keys from meta to the hash.

This function is not exported by default, but exportable.

Arguments ('*' denotes required arguments):

• arg* => array|hash

• meta => hash

  Metadata (extra keys) for the hash.

Return value: (hash)
