Emacs completion at point function (capf) for vhdl-mode.
This file provides a completion at point function (capf) for the vhdl major mode. To use this correctly, the vhdl major mode has to be enabled and working (which is by default the case for newer Emacs installations). The basic intention for this minor mode is completion with fuzzy matching. If you don't want this better ignore this package and stick with the vhdl major-mode's own completion. To get auto-completion with fuzzy matching, some completion toolkit has to be enabled that is able to do fuzzy matching and uses cap-functions. This could be achieved by company-mode with enabled company-flx package. So install and activate those two first (or another completion framework like auto-complete) then use this vhdl completion at point function.
If you don't use a package managing system like melpa, you have to include
this file by hand, using (load-path "/path/to/where/this/file/resides").
After this (and if installing by melpa) you can enable the capf by the following
in your .emacs file:
(when (require 'vhdl-capf)
(vhdl-capf-enable))There is mainly one parameter that can be set by the user, according to his needs: vhdl-search-completion-buffers. As stated in the belonging comment, the value of this variable controls the amount of other buffers that is being searched for completion candidates. In principle there are two settings: t and a number. If this is t ALL available buffers with the vhdl major-mode will be searched. If the value is a number, the (number+1) last opened buffers with vhdl major-mode will be searched. But: the search for completion candidates is cached. This means the active vhdl-buffer is searched for candidates every time the capf is invoked. All other vhdl-buffers that shall be searched are just scanned once and after that the cached word list is taken.
