The above template will convert:
psm_mas ms2m (/*AUTOINST*/);
Typing \\[verilog-auto] will make this into:
psm_mas ms2m (/*AUTOINST*/
// Outputs
.PO_PSM_PFRAME_L (PO_PSM_PFRAME_L),
.INSTDATAOUT (INSTDATAOUT2),
.PTL_MAPVALIDX (PTL_MAPVALID[2]),
.PTL_MAPVALIDP1X (PTL_MAPVALID[3]),
....
// Inputs
....
.INSTDATA (INSTDATA[2]),
.PI_PPAR64_L (PI_PPAR64_L));
Note the ＠ character was replaced with the 2 from \"ms2m\". Also, if a
signal wasn't in the template, it is assumed to be a direct connection.

(defun verilog-auto-sense ()
"Replace the always (/*AUTOSENSE*/) sensitivity list with one
automatically derived from all inputs declared in the always statement.
Signals that are generated within the same always block are NOT placed into
the sensitivity list (see verilog-auto-sense-include-inputs).
Long lines are split based on the fill-column, see \\[set-fill-column].
Limitiations:
The end of a always is considered to be a ; unless a begin/end is used.
This is wrong for \"always if foo else bar\", so use begin/end pairs
after always!
Verilog does not allow memories (multidimensional arrays) in sensitivity
lists. AUTOSENSE will thus exclude them, and add a /*memory or*/ comment.
Constant signals:
AUTOSENSE cannot always determine if a `define is a constant or a signal
(it could be in a include file for example). If a `define or other signal
is put into the AUTOSENSE list and is not desired, use the AUTO_CONSTANT
declaration anywhere in the module (parenthesis are required):
/* AUTO_CONSTANT ( `this_is_really_constant_dont_autosense_it ) */
Better yet, use a parameter, which will be understood to be constant
automatically.
OOps!
If AUTOSENSE makes a mistake, please report it. As a workaround, if
a signal that shouldn't be in the sensitivity list was, use the
AUTO_CONSTANT above. If a signal should be in the sensitivity list
wasn't, placing it before the /*AUTOSENSE*/ comment will prevent it from
being deleted when the autos are updated.
A simple example:
always ＠ (/*AUTOSENSE*/) begin
/* AUTO_CONSTANT (`constant) */
outin <= ina | inb | `constant;
out <= outin;
end
Typing \\[verilog-auto] will make this into:
always ＠ (/*AUTOSENSE*/ina or inb) begin

Before I go further, I want to say that Verilog mode has changed my life.
I save so much time, my files are colored nicely, my co workers respect
my coding ability... until now. I'd really appreciate anything you
could do to help me out with this minor deficiency in the product.
To reproduce the bug, start a fresh Emacs via " invocation-name "
-no-init-file -no-site-file'. In a new buffer, in verilog mode, type
the code included below.
Given those lines, I expected [[Fill in here]] to happen;
but instead, [[Fill in here]] happens!.

"Replace the argument calls inside an instantiation with ones

Limitations:
This presumes a one-to-one port name to signal name mapping.
Module names must be resolvable to filenames, either by being in the same
directory, or by changing the variable verilog-library-directories.
Macros `modname are translated through the vh-{name} emacs variable,
if that is not found, it just ignores the `.
A simple example:
module ex_inst (o,i)
output o;
input i;
inst inst (/*AUTOINST*/);
endmodule
Where somewhere the instantiated module is declared:
module inst (o,i)
output [31:0] o;
input i;
wire [31:0] o = {32{i}};
endmodule
Typing \\[verilog-auto] will make this into:
module ex_inst (o,i)
output o;
input i;
inst inst (/*AUTOINST*/
// Outputs
.ov (ov[31:0]),
// Inputs
.i (i));
endmodule
Where the list of inputs and outputs came from the inst module.
For multiple instantiations based upon a single template,
Create a commented out template:
/*
psm_mas AUTO_TEMPLATE (
.PTL_MAPVALIDX (PTL_MAPVALID[＠]),
.PTL_MAPVALIDP1X (PTL_MAPVALID[＠\"(% (+ 1 ＠) 4)\"]),
);
*/
where the ＠ character should be replaced by the instantiation number. The
module name must be the same as the name of the module in the instantiation
name, and the code \"AUTO_TEMPLATE\" must be in these exact words and
capitalized. Only signals that must be different for each instantiation
need to be listed.
If the syntax ＠\"( ... )\" is found, the expression in quotes will be
evaluated as a lisp expression, with ＠ replaced by the instantation number.
The example above would put ＠+1 modulo 4 into the brackets. Quote all
double-quotes inside the expression with a leading backslash (\").

update verilog-mode.el (1/6)

Neal D. Becker
Neal D. Becker
I have received an updated verilog-mode.el from the maintainer. I
made a couple of very simple changes - because it explicitly looked
for xemacs version number 20. I think my changes are probably OK.
Here it is:
;;; verilog-mode.el --- major mode for editing verilog source in Emacs
;;
;; $Id: verilog-mode.el,v 1.1 1998/10/07 17:48:13 nbecker Exp nbecker $

;;; Commentary:
;;; This mode borrows heavily from the Pascal-mode and the cc-mode of emacs
;;; USAGE
;;; =====
;;; A major mode for editing Verilog HDL source code. When you have
;;; entered Verilog mode, you may get more info by pressing C-h m. You
;;; may also get online help describing various functions by: C-h f
;;; <Name of function you want described>
;;; You can get step by step help in installing this file by going to
;;; <http://www.surefirev.com/emacs_install.html>
;;; The short list of installation instructions are: To set up
;;; automatic verilog mode, put this file in your load path, and put
;;; the following in code (please un comment it first!) in your
;;; .emacs, or in your site's site-load.el
; (autoload 'verilog-mode "verilog-mode" "Verilog mode" t )
; (setq auto-mode-alist (cons '("\\.v\\'" . verilog-mode) auto-mode-alist))
; (setq auto-mode-alist (cons '("\\.dv\\'" . verilog-mode) auto-mode-alist))
;;; If you want to customize Verilog mode to fit your needs better,
;;; you may add these lines (the values of the variables presented
;;; here are the defaults). Note also that if you use an emacs that
;;; supports custom, it's probably better to use the custom menu to
;;; edit these.
;;;
;;; Be sure to examine at the help for verilog-auto, and the other
;;; verilog-auto-* functions for some major coding time savers.
;;;
; ;; User customization for Verilog mode

(defun verilog-mode ()
"Major mode for editing Verilog code. \\<verilog-mode-map>
NEWLINE, TAB indents for Verilog code.
Delete converts tabs to spaces as it moves back.
Supports highlighting.
Variables controlling indentation/edit style:
verilog-indent-level (default 3)
Indentation of Verilog statements with respect to containing block.
verilog-indent-level-module (default 3)
Absolute indentation of Module level Verilog statements.
Set to 0 to get initial and always statements lined up
on the left side of your screen.
verilog-indent-level-declaration (default 3)
Indentation of declarations with respect to containing block.
Set to 0 to get them list right under containing block.
verilog-indent-level-behavioral (default 3)
Indentation of first begin in a task or function block
Set to 0 to get such code to linedup underneath the task or function keyword
verilog-cexp-indent (default 1)
Indentation of Verilog statements broken across lines IE:
if (a)
begin
verilog-case-indent (default 2)
Indentation for case statements.
verilog-auto-newline (default nil)
Non-nil means automatically newline after semicolons and the punctation
mark after an end.
verilog-auto-indent-on-newline (default t)
Non-nil means automatically indent line after newline
verilog-tab-always-indent (default t)
Non-nil means TAB in Verilog mode should always reindent the current line,
regardless of where in the line point is when the TAB command is used.
verilog-indent-begin-after-if (default t)
Non-nil means to indent begin statements following a preceding
if, else, while, for and repeat statements, if any. otherwise,
the begin is lined up with the preceding token. If t, you get:
if (a)
begin // amount of indent based on verilog-cexp-indent
otherwise you get:
if (a)
begin
verilog-auto-endcomments (default t)
Non-nil means a comment /* ... */ is set after the ends which ends
cases, tasks, functions and modules.
The type and name of the object will be set between the braces.
verilog-minimum-comment-distance (default 10)
Minimum distance (in lines) between begin and end required before a comment
will be inserted. Setting this variable to zero results in every
end aquiring a comment; the default avoids too many redundanet
comments in tight quarters.
verilog-auto-lineup (default `(all))
List of contexts where auto lineup of :'s or ='s should be done.
Turning on Verilog mode calls the value of the variable verilog-mode-hook with
no args, if that value is non-nil.
Other useful functions are:
\\[verilog-complete-word]\t-complete word with appropriate possibilities
(functions, verilog keywords...)
\\[verilog-comment-region]\t- Put marked area in a comment, fixing
nested comments.
\\[verilog-uncomment-region]\t- Uncomment an area commented with \
\\[verilog-comment-region].
\\[verilog-insert-block]\t- insert begin ... end;
\\[verilog-star-comment]\t- insert /* ... */
\\[verilog-mark-defun]\t- Mark function.
\\[verilog-beg-of-defun]\t- Move to beginning of current function.
\\[verilog-end-of-defun]\t- Move to end of current function.
\\[verilog-label-be]\t- Label matching begin ... end, fork ... join
and case ... endcase statements;

[bug] pcl-cvs provides wrong in package-get-base

Greg Klanderman
package-get-base.el (last incremental one) says for pcl-cvs:
provides (pcl-cvs dll elib-node generic-sc)
but should say:
provides (pcl-cvs pcl-cvs-xemacs generic-sc)
as the elib stuff was moved.

font-menu-this-frame-only-p
27 years
Charles G Waldman
Charles G Waldman
According to the docstring:
font-menu-this-frame-only-p' is a variable declared in Lisp.
-- loaded from "/usr/local/lib/xemacs-21.0/lisp/auto-autoloads"
*If non-nil, then changing the default font from the font menu will only
affect one frame instead of all frames.
This variable gets set by the menu item
Options/Frame Appearance/Frame-Local font menu
But, at least for me, on XEmacs 21.0 "Poitou" it doesn't work -
using the font menu changes the fonts in ALL frames, regardless of the
setting of font-menu-this-frame-only-p
Y'all probably know about this already - I'm well aware that there are
lots of outstanding issues re: fonts and the options menu.
I'll try to work on a fix, but would appreciate guidance from somebody
who understands Customize a little better than I do.
