This is what I would do: In a dired buffer of the ~/bin/emacslib
directory, mark the .el files with 'M' and then byte-compile them with
'B'.

Thank you. Emacs 23.1 on Mac OSX works.
But when I start emacs at terminal (instead of running Emacs.app),
emacs (in /usr/bin/emacs version 22)  complains that the .elc are
compiled for version 23.

Can you please tell me what can I do to fix this?

Thank you.

Hi,

Having two different version of any program installed is a sure way to  
go mad.

I would suggest that you remove /usr/bin/emacs from the system (and  
emacslient et al) , and add the path to the Emacs 23.1 binary. I have  
first in my PATH variable the /Applications/Emacs.app/Contents/MacOS/:/ 
usr/bin: in my


With kindest regards

X fonts handling in 23.1

[Dmitry Antipov]

Hello all,

my ~/.Xdefaults contains:

Emacs*font: -misc-*

And 22.3 starts with the expected font. But 23.1 doesn't.

Moreover, I can start 22.3 with '-fn fixed' and then do
(set-frame-font "-misc-*"), and it toggles the font
as expected. But, again, not for 23.1.

Both versions are configured with:

./configure --without-dbus --without-rsvg --without-sound \
             --with-x-toolkit=lucid --without-xft --without-pop

I've tried with '-Q' and with 'LANG=C', but it doesn't matter.

This issue was observed on two Fedora 10 and Fedora 11 systems.

Font handling in 23 is all new and supports antialiased fonts. Check the
NEWS file for details. 

I found I had to add 

Emacs.fontBackend: xft

to my .Xresources file in order to get fonts working correctly. 
This is on a Debian testing/unstable box. 

Why are you building with lucid rather than the default GTK? Also, why
disable dbus support? Did the output from ./configure give anything
useful? 

Given its a new release, I'd be inclined to build just using all
defaults to start with and then see if that works and slowly remove what
you don't want. This is also a good way to see how things have changed
and then enable you to re-evaluate what is not required. 

For the last month or so, the commands I've used to build (from CVS) are 

./configure prefix=/usr/local
make bootstrap 
make install

The font I'm using is -fn "DejaVu Sans Mono-14" and it works very
nicely.

The easy way is to also use emacs 23 in the terminal,
/path/to/your/emacs -nw should do it. Or just fix your PATH
environment variable so that your emacs 23 bin directory comes first.

Otherwise you'd have to use different directories for different emacs
version + one directory with the .el sources. You'd symlink your
source files over to the directories for your different emacs versions
and compile them there. This is more or less how debian's emacs
packaging works when you have multiple emacsen installed. 

In your .emacs you'd to something like this:

  (add-to-list 'load-path 
               (format "/path/to/emacs-lisp/emacs-%s" emacs-major-version))

But I'd rather use emacs 23 on the console as well. With the new
multi-tty feature you should also be able to use the same instance for
this, issue M-x server-start and then connect with `emacsclient -t'. I
heard that multi-tty doesn't yet work well on OS X, though.

HTH, 

Anselm

OK, then maybe you should rather not use Emacs at all but switch to
Textmate. 8;-)

Surprisingly, I don't think anybody answered your question correctly
yet. So here's my lame attempt ....

Anyways, it's incompatible now due to changes in 23.1. You'll have to
compile with 22, I suppose, which will still work with 23.

(quoting from NEWS):

"During byte-compilation, Emacs 23 uses `utf-8-emacs' to write files.
As a result, byte-compiled files containing non-ASCII characters can't
be read by earlier versions of Emacs.  Files compiled by Emacs 20, 21,
or 22 are loaded correctly as `emacs-mule' (whether or not they
contain multibyte characters).  This takes somewhat more time, so it
may be worth recompiling existing .elc files which don't need to be
shared with older Emacsen."

How to speed up emacs start time?

[n179911]

In my .emacs, I have

(setq load-path (cons "~/bin/emacslib" load-path))
(require 'icicles)

And in my ~/bin/emacslib, I have

$ ls
icicles-chg.el   icicles-doc1.el  icicles-fn.el    icicles-mode.el  icicles.el
icicles-cmd1.el  icicles-doc2.el  icicles-mac.el   icicles-opt.el
icicles-cmd2.el  icicles-face.el  icicles-mcmd.el  icicles-var.el

Can you please tell me how can I speed up emacs startup time? Is there
anyway to compile the .el. files so that emacs can come up faster?

Thank you.

1. C-x d ~/bin/emacslib

2. Use `m' to mark each of the icicles files, except *-chg* and *-doc*.

3. `B', then confirm, to byte compile all of the marked files.

You're done.

If you modify any of the source files that you've byte-compiled (e.g. you
downloaded a later version), you can use `M-x byte-recompile-directory' to
recompile any that whose *.elc files are out of date. That's like a mini-`make'
for byte-compiled files.

Can't you just `M-x byte-recompile-directory' on the first instance?

`byte-recompile-*' only RE-compiles. It does not compile any *.el in the
directory that have not already been compiled. This means you can keep some
files uncompiled, yet still keep the *.elc up-to-date using `byte-recompile-*'.

Unless you use a prefix argument.

Right. It's good to remind about that.
