Vhdl
Mode
Additions
This contains only the additional functions written by me as an addition to
the vhdl-mode.el original file.
;;; Some modifications were made to the original file by Rajkumar Kadam
;;; Email : rkadam@usa.net
;;; Auto loading of header for a new vhdl file, multiple component instantiation
;;; were the features added.
;;; The features are not thoroughly checked.
;;; Improper use of the features may crib

;; Description
;; ############################################################################
;; This package for VHDL code features:
;; - Highlighting of keywords, comments, built-in types, and strings
;; - Indentation based on versatile syntax analysis (by Rod Whitby)
;; - Electrification (automatic template generation) for most VHDL constructs
;; - Word completion (dynamic abbreviations)
;; - Menu containing all VHDL mode commands
;; - Index menu (jump index to main units and blocks in a file)
;; - Source file menu (menu of all source files in current directory)
;; - Source file compilation (syntax analysis)
;; - Postscript printing with fontification
;; - Lower and upper case keywords
;; - Easy customization
;; - Works under GNU Emacs and XEmacs
;; ############################################################################
;; Emacs Versions
;; ############################################################################
;; - GNU Emacs 19.34 (intensively tested, all features supported)
;; - GNU Emacs 20.2 (marginally tested, all features supported)
;; - XEmacs 19.15 (marginally tested, most features supported)
;; ############################################################################
;; Installation
;; ############################################################################
;; - Install the files at your Emacs installation site
;; or put it in an arbitrary directory and add the following line to
;; your Emacs startup file (`.emacs'). `vhdl-mode.elc' is compiled for
;; GNU Emacs. For XEmacs, re-compile it using the command
;; `xemacs -batch -q -no-site-file -f batch-byte-compile vhdl-mode.el'.
;; (setq load-path (cons (expand-file-name "") load-path))
;; - Add the following lines to your Emacs startup file (`.emacs')
;; Adapt the variable settings to your needs.
