VHDL and Emacs (My experience)

VHDL and Emacs (My experience)

[mans]

Hello,

     I am new in VHDL and Emacs and I tried to use Emacs for editing VHDL 
and attaching it to ISE. My experience is as follow:



Overall:



Emacs has a very good editor for VHDL editing. It has several good features 
such as auto indentation and syntax highlighting. Over all it is very good 
if you can use it (I could not!)



What I did:

I download my copy of Emacs from 
http://www.ourcomments.org/Emacs/EmacsW32.html . I installed it in my 
windows XP professional system and setup ISE to use it. It works well with 
ISE.



Problems that I had:



1-      Its keyboard shortcuts are not windows based. I tried to configure 
wmacsw32 without any success.

2-      It is very slow to start ( I didn't use emacs clinets)

3-      I read that you can see a hierarchy of your VHDL code, but I can not 
turn it on (I don't know how to turn it on!).

4-      I can not find any documentation on facilities which are available 
in VHDL mode.

5-      Some times when I try to click on VHDL menu, this menu item 
disappears!



Best regards

True, but the the arrow keys, and mouse, and menus
work without knowing any shortcuts.

True. I just leave it running all day.

That requires vhdl-mode and speedbar.
vhdl-mode.el is not included in most windows distributions,
get it here:

Not like it support Java.

Can you please tell me what you did and how it failed? There is a quick 
setup for those things if you use the menus:

    Options - Customize EmacsW32 ...

You should use EmacsClient and only start Emacs once.

Making it easy to get started using EmacsClient is one of the main 
things the installer for Emacs+EmacsW32 is trying to help you with. 
Several shortcuts gets installed that lets you start Emacs through 
EmacsClient. There is one in the start menu and you get one in the 
SendTo menu. If you prefer working from the command line there is a 
command line script called e.cmd for this.

If you use the patched version then Emacs server gets started 
automatically through those shortcuts and or the command line scripts. 
(For the unpatched version you have to start Emacs server yourself, 
please read the Emacs manual.)

  Can you please describe this more? Exactly when does this happen?

I did use this option and it didn't work for me. I set the CUA in option and 
it is working. One point that probably confuse people is that even in this 
case, the short cuts in edit menu is not C-x and C-c and so on.

I think I don't have the patched version. I will try to see what I can do 
with this but  as long as I am not closing emacs after each edit, I don't 
need to restart it. I am happy!

It happens before to me but it is working well now. I will post the details 
if it happens again to me.





More on new and old problems that I have:



1- I can set speedbar and used it. It is a very useful facility. The problem 
is that I can not dock it into emacs. Is there any way to dock it into emacs 
so it doesn't start as a new window?

2- If I have a file that I modified with ISE, when I open it with Emacs, I 
can see a ^M at the end of each line. This generates error during 
indentation. I could not find any way to fix it. I only can remove them 
manually which is time consuming. Any way to do this in emacs or ISE or by 
any other tools?



One suggestion:

  As during editing, it is possible to edit several files, is there any way 
to save all files just by pressing a button on toolbar or a menu item?



My view of emacs for editing VHDL is no changed and I am very happy to use 
it with VHDL.



Best regards and thanks for helping to use emacs.

I downloaded emacs - windows version from http://www.ourcomments.org/cgi-bin/emacsw32-dl-latest.pl
(Download Latest EmacsW32 + Emacs patched).
It supports vhdl mode. Its really good. You can give a try.

If you use it with ISE, would you please tell me how did you setup ISE to 
use it?
In my setup, emacs is runs every  time and also when I click on an error in 
ISE, it can not bring me to the specific line in the source code.

I know nothing about ISE, but is sounds like you have bound it to Emacs 
directly instead of to emacsclientw.exe / emacsclient.exe.

No, I am not using Emacs with ISE.  For Design Entry I am using
Emacs32 only and in this, I set Compiler as Modelsim.
So, once I complete my coding, I do compilation in Emacs32 itself to
check syntax errors if any.

I use Emacs with ISE -
go to http://www.xilinx.com/xlnx/xil_ans_display.jsp?iLanguageID=1&iCountryID=1&getPagePath=13713
to find out how to integrate emacs with ISE.

I just did. That's the best windows install I've seen.
Speedbar and vhdl-mode are built-in and *work*.

However, I'll keep my linux box until
there is a real shell integrated
just as well.

That indicates that your file is stored with odd line endings.

Generally there are two styles of line ending, "Carriage Return" +
"Line Feed" CRLF which is used in MSDOS.  And simple Line-Feed (LF)
endings, used in Unix and now in Windows.

What Emacs does is to read the file and find out which sort of endings
are in use and automatically default to the right ones.  The problem
here is likely that you are saving the file with LF endings and
opening it again with ISE which uses CRLF endings.  Emacs doesn't
expect the endings to change as you edit the file.

The solution is probably to open and save the files initially using
CRLF endings.  So, to fix this open up your file using Emacs and type
C-x RET f "dos" RET.  Or select the menu Options->Mule->Set coding
systems->For Saving this Buffer.

Post again if doing the above doesn't work.

You could try the Zeus for Windows IDE:

   http://www.zeusedit.com
   NOTE: Zeus is shareware.

It should be easy enough to configure Zeus for VHDL.

FWIW the next Zeus release will come with better configuration
for VHDL and will also add code folding for the VHDL language.

The Zeus keyboard is Windows aware and is also fully configurable.

Generally Zeus will load in less than a second.

Zeus provides code hierarchy via the information provided by
the ctags utility.

I am not sure if ctags supports VHDL, but if it does this information
should apear in the class panel of the navigator.

This sounds like a good start. Don't let yourself get discouraged.

Personally, I use XEmacs (Linux, Win32 native) which might be a little
different. Here, the old-school windows shortcuts for copy/paste do work
(C-Insert, S-Insert, etc.). The others, C-c in particular won't and I
would not recommend changing the mappings. pc-select mode gives you
the selection behavior using S-right/left/up/down (cursor keys).

Depends on what your config file looks like. I'd consider using the
clients.

You will have to load a package called "speedbar". If that has not
been installed already you can get it from
    http://cedet.sourceforge.net/

I use xemacs with cua mode and it handles most of the windows
shortcuts (including C-c, C-x and C-v). I had to set another couple of
options to get it to treat the selected text as "pending delete" too.
I just wish there was a handy way to select a word or phrase in the
code and then search for other occurrences of it, with minimal
additional typing. There probably is, but I just don't know it yet!

If you really cannot stomach the rest of the emacs wizardy, try jGrasp
(free) from University of Auburn. It has very good highlighting and
indentation (it does not autocapitalize). It also can insert Control
Structure Diagram (CSD) graphics in the left margin/whitespace
including buttons for collapsing/expanding code segments, etc. Mousing
over the appropriate CSD graphic then shows you the top of that
control structure (process/loop/if-then/case, etc), and if it was off
screen, it temporarily shows it on the top row. It uses java and is
portable between unix/linux and windows, but it is not slow like some
other java based editors.

You were writing about XEmacs, which I'm not very familiar with. But in GNU
Emacs, at least as far back as version 20, you can use `M-y' during
incremental search to search for the text in the region. So, just "select a
word or phrase in the code" in whatever way you like (e.g. mouse), and use
`M-y' during isearch to append that text to the search pattern.

Hi Andy,

Does C-s, M-y do what you want?

This calls up a search and pastes your previous copy into it.  I have
C-s bound to isearch-forward, which may be non-default.  C-s might be
a normal (non-incremental) search, in which case, C-s, C-y might do
the trick?

Alternatively, "M-x occur" is useful, it opens another window listing
which lines a particular phrase (well, regexp) occurs in.  If you
like it, bind a key for that too :-)

I also have a key bound to mark and copy the word/signalname/etc that
is under the cursor, all in one go. which is quite handy for these
sorts of things...

Cheers,
Martin

I do that with query-replace.

Like most tasks, it's easy once you know how to do it :)

C-s

Then type enough letters to see the instances light up.

C-s again to jump to the next instance, etc.

Mike,

Thanks, but I already know how to use C-s (that's what I end up
using). Unfortunately, it still requires me to type the word (or
enough of it to be sufficiently unique) to start the search. I was
looking for something that allows me to select an existing word,
usually a port or signal/variable name (with mouse or keyboard), and
search for other occurrences of that word. Typing the entire word gets
tedious when using long names with specific suffixes, which require
that virtually the entire name be re-typed. When in I-search (C-s), a
C-v (paste) does not act like I typed it, but actually inserts the
copy buffer at the cursor location. It's like the C-v operation
overrides the fact that one is already in I-search mode.

C-s M-y appends copied text to the search string.

C-s M-w appends the word starting at the cursor to the search string.
Use additional M-w to append additional words.

Should that be C-s C-w?

Yes, sorry. That's what happens when the fingers typing about fingers typing
don't talk to the typing fingers before typing.

You can use M-y to yank (ie paste) text into the C-s search string.

I would just mark with the mouse then, C-s
and paste into the mini-buffer with
the center mouse key. Then C-s, C-s, ...

Mike,

Thanks! that works!

Is there a keyboard equivalent of center mouse key?

Go with point (cursor) on the first letter of a word then:
C-s C-w or for expanding the marking
C-s C-w C-w ...

As has been stated by several people in this thread already:
during incremental search, `M-y'.

(Outside of incremental search, the equivalent is of course `C-y'.)

Well, there is a function.
C-h k click2 says:

<mouse-2> at that spot runs the command mouse-insert-selection
   which is an interactive compiled Lisp function in `mouse-sel'.
(mouse-insert-selection EVENT)

But if I don't press the mouse button
there is no interrupt, and I don't get the
right coordinates.

In any case, Pontus has already converted me
to click1, C-s, C-w, ...
That's easier on my right hand.
