Return a list of command-line completion matches. The String {type} argument specifies what for. The following completion types are supported: arglist file names in argument list augroup autocmd groups buffer buffer names behave |:behave| suboptions breakpoint |:breakadd| and |:breakdel| suboptions color color schemes command Ex command cmdline |cmdline-completion| result compiler compilers cscope |:cscope| suboptions diff_buffer |:diffget| and |:diffput| completion dir directory names environment environment variable names event autocommand events expression Vim expression file file and directory names file_in_path file and directory names in |'path'| filetype filetype names |'filetype'| function function name help help subjects highlight highlight groups history |:history| suboptions locale locale names (as output of locale -a) mapclear buffer argument mapping mapping name menu menus messages |:messages| suboptions option options packadd optional package |pack-add| names scriptnames sourced script names |:scriptnames| shellcmd Shell command sign |:sign| suboptions syntax syntax file names |'syntax'| syntime |:syntime| suboptions tag tags tag_listfiles tags, file names user user names var user variables If {pat} is an empty string, then all the matches are returned. Otherwise only items matching {pat} are returned. See |wildcards| for the use of special characters in {pat}. If the optional {filtered} flag is set to 1, then 'wildignore' is applied to filter the results. Otherwise all the matches are returned. The 'wildignorecase' option always applies. If the 'wildoptions' option contains 'fuzzy', then fuzzy matching is used to get the completion matches. Otherwise regular expression matching is used. Thus this function follows the user preference, what happens on the command line. If you do not want this you can make 'wildoptions' empty before calling getcompletion() and restore it afterwards. If {type} is "cmdline", then the |cmdline-completion| result is returned. For example, to complete the possible values after a ":call" command: echo getcompletion('call ', 'cmdline') If there are no matches, an empty list is returned. An invalid value for {type} produces an error. Can also be used as a |method|: GetPattern()->getcompletion('color')
