Setting font to Lucida Grande on Mac OS X

Setting font to Lucida Grande on Mac OS X

[Sancho Neves-Graca]

I am running Emacs 21.3.50 Carbon Mac OS X 10.2.6.

I would like to change the font of a frame from the default (Monaco) to 
the system default (Lucida Grande). For other fonts which are named by 
a single word the following commands work:

M-x set-frame-font RET -*-Monaco-*-120-*
M-x set-frame-font RET -*-Courier-*-120-*
M-x set-frame-font RET -*-Helvetica-*-120-*

But the command

M-x set-frame-font RET -*-LucidaGrande-*-120-*

returns Font '-*-LucidaGrande-*-120-*' is not defined.

What is the name known to Emacs for Lucida Grande? If a space is 
needed, how is it entered (pressing Space returns [No Match])?

Further, what entry in ~/.MacOSX/environment.plist is necessary to set 
this new font as the default for any new frame?

Setting font to Lucida Grande on Mac OS X

[Sancho Neves-Graca]

I am running Emacs 21.3.50 Carbon Mac OS X 10.2.6.

I would like to change the font of a frame from the default (Monaco) to 
the system default (Lucida Grande). The following fonts can be set:

M-x set-frame-font RET -*-Monaco-*-120-*
M-x set-frame-font RET -*-Courier-*-120-*
M-x set-frame-font RET -*-Helvetica-*-120-*

But putting in ~/.emacs

(set-default-font "-*-Lucida Grande-*-120-*")

returns Font '-*-Lucida Grande-*-120-*' is not defined.

Is Lucida Grande available for Emacs on Mac OS X? If so, what is its 
identifier?

I can answer the second part of the question: C-q then space.
I would guess that this will just tell you that the font is not
defined, but you can always try.

Are you _sure_ that there _is_ a font '-*-Lucida Grande-*-120-*' on
your system?  The C-q trick worked perfectly for me.  I do not have
Lucida Grande on my system, but I successfully tried 
M-x set-frame-font <RET> -*-century schoolbook-* (with C-q <SPC>).

I use GNU/Linux and do not know whether you can run `xlsfonts' on Mac
OS X.  If you can, try:

xlsfonts -fn '-*-Lucida Grande-*'

You said that 'Lucida Grande' was the system default, but what about
the '-120' part?  Is that the system default too?  Is it available?

Sincerely,

Luc.

The actual answer to this may be a little bit more complicated than I
thought at first.

As I already said, I do not have Lucida Grande, but I believe the
situation must be very similar to `century schoolbook'.

>From one of my previous messages:

[bash2.05b.0 ~ 3 6] xlsfonts -fn '-*-century schoolbook-*'
-abisource-century schoolbook-bold-i-normal--0-0-0-0-p-0-iso8859-1

xlsfonts: pattern "-*-century schoolbook-*-120-*" unmatched
[bash2.05b.0 ~ 3 8]

Take the first entry xlsfonts found:

-abisource-century schoolbook-bold-i-normal--0-0-0-0-p-0-iso8859-1

I figured out using `xfd' (may or may not be available on Mac OS X)
that this font is identical with:

'-abisource-century schoolbook-regular-r-normal--17-120-100-100-p-94-iso8859-1'

`emacs-21.3.50 -fn' works perfectly with the last expression.

However, if you put *'s in the wrong places in the last expression,
in particular '-*-century schoolbook-*-120-*', neither 

emacs-21.3.50 -fn 'stuff-with-*'s'

nor

xlsfonts -fn 'stuff-with-*'s'

believe there is _any_ matching font.

I believe this has something to do with the following quote from the
xlsfonts man page:

       -o      This option indicates that xlsfonts should  do  an
               OpenFont  (and  QueryFont,  if appropriate) rather
               than a ListFonts.  This is useful if ListFonts  or
               ListFontsWithInfo fail to list a known font (as is
               the case with some scaled font systems).

The -o option does not help in this case, however, still no matches.

As xlsfonts can not handle this either, I do not believe that this is
a bug in Emacs, but I am not a real expert in these matters.

Sincerely,

Luc.

1. Please use gnu.emacs.help to ask user questions.

2. I don't recommend using truetype fonts that do not contain fixed-size
   variants because the Mac emulation code for these fonts isn't
   complete (since we're on a developers list, I invite everyone to work
   on it), but if you must, do something like this:

M-x set-frame-font RET -apple-lucida grande-medium-r-normal--12-0-75-75-m-0-mac-roman

I guess that gets rid of Sancho's concrete problem, but it does not
answer the following question:

Why does

M-x set-frame-font RET -*-Courier-*-120-*

work and

M-x set-frame-font RET -*-Lucida Grande-*-120-*

not?

Maybe `-*-Lucida Grande-*-120-*' really is unmatched (I can not
check), but look at the example below.

The difference between a user question belonging on `gnu.emacs.help'
and a question belonging on this site is that the answer to the former
could have been found in the standard documentation, in this case the
Emacs manual.

>From (emacs)Font X :

    You can use wildcard patterns for the font name; then Emacs lets X
    choose one of the fonts that match the pattern.

Not quite.  Emacs (or X) will not be able to find some fonts this way.
Neither will xlsfonts.  I guess that if I were an expert on fonts, the
example below would be obvious to me, but I believe that being an
expert on fonts should not be a prerequisite to being able to specify
a font for Emacs.

[bash2.05b.0 ~ 3 1] emacs-21.3.50 -fn
'-abisource-courier-bold-i-normal--17-120-*-*-*-*-*' 
No fonts match `-abisource-courier-bold-i-normal--17-120-*-*-*-*-*'
[bash2.05b.0 ~ 3 2] emacs-21.3.50 -fn
'-abisource-courier-bold-i-normal--17-120-*-*-*-*-*-*'
[bash2.05b.0 ~ 3 3] 

Why does the second line work and the first one not?  Does `*' not
match `*-*' anyway?  It does for `-*-Courier-*-120-*'.

Is it possible to tell in one or two lines in (emacs)Font X what is
going on here?  Or am I missing something truly obvious (even to non
font experts)?

Sincerely,

Luc.

Re: Setting font to Lucida Grande on Mac OS X

[Sancho Neves-Graca]

Thanks to Luc and Andrew for their replies. My posting fell somewhere 
between a user problem and a development issue. From the point of view 
of a user, he would check on the documentation for how to set a desired 
font on a frame, namely the font used by his operating system per 
default. But as soon as it is apparent that Emacs does not seem to know 
about such font, it does become a development question. Andrew 
clarified that the Carbon implementation of Emacs does not directly 
make use of the native TrueType font. Thus fonts kept in 
/System/Library/Fonts are not directly used by Emacs. There does seem 
to me to be a scarce availablity of fonts for the Emacs Carbon 
implementation. The default font (Monaco) is in my opinion hard on the 
eyes either for source code or XML editing, because the vertical to 
horizontal ratio of a letter box is too high. Contrast that with the 
default font setting of Project Builder (Lucida Grande Regular 11 pt), 
where the letters are much more well-rounded and pleasing to the eye. 
One working solution is to use good old Courier ("-*-Courier-*-140-*"). 
I have now built Emacs on Mac OS X using X11 and the offered fonts are 
others than those that can be set with the Carbon implementation and 
again Courier looks the best compromise. Perhaps with the X11 build new 
fonts for Emacs can more readily be installed.

I believe this is probably a bug in the relevant Xlib or server
routines.  The problem is mostly like due to the fact that '*' can
match any number of characters, and does not respect field
boundaries.  Furthermore, the standard is not terribly specific about
how to deal with target font names which are themselves wildcards (ie,
scalable, with 0 for all dimensions.

If you want to have a reasonably good expectation of getting a match,
use a fully qualified XLFD.  xfontsel is a convenient way to produce
these.  The technical definition is more complex, but you'll hardly
ever go wrong if you think of "fully qualified XLFD" as "containing
exactly 14 hyphens, and starting with a hyphen".

Especially in a world where we (at least sometimes) ask Windows and
Mac users to specify XLFDs for their fonts, I think this should be in
the Emacs manual.

On '-abisource-courier-bold-i-normal--17-120-*-*-*-*-*' 
vs. '-abisource-courier-bold-i-normal--17-120-*-*-*-*-*-*':

Experience shows that different implementations of X11 do different
things given the same set of fonts and the same specs.  So you may as
well just chalk it up to "implementation dependent, and therefore
potentially random, behavior".  Use the 14-hyphen XLFD.

I also replaced the `eleven' in:

    Under X, each font has a long name which consists of eleven words or
    numbers, separated by dashes.

by `fourteen', because this seems like an obvious error.  An XLFD
contains fourteen fields, even though one of these is usually empty.

The "charset" portion is actually composed of 
var{registry}-@var{encoding}, so it might be useful to make that clear, 
otherwise the reader might wonder where the 14th field went.

Re: Setting font to Lucida Grande on Mac OS X

[Luc Teirlinck]

What about the following patch, which incorporates the suggestions
made by Stephen and Jason?  It still refers at one point to the
combined "registry-encoding" entity as a "character set", because I
believe that will make more sense to most people than "registry" and
"encoding", but I point out that it is not identical with MULE
character sets.

Re: Setting font to Lucida Grande on Mac OS X

[Richard Stallman]

    What about the following patch?  I could commit it if desired.
    I also replaced the `eleven' in:

	Under X, each font has a long name which consists of eleven words or
	numbers, separated by dashes.

    by `fourteen', because this seems like an obvious error.  An XLFD
    contains fourteen fields, even though one of these is usually empty.

I don't know much about this, so please do what seems right.

    ! These make up the character set that the font depicts.  Note that this
    ! is different from MULE character sets.  You can use the
    ! @command{xfontsel} program to check which choices you have.

I suggest this replacement for that particular point:

    These together make up the X font character set that the font
    depicts.  (X font character sets are not the same as Emacs
    character sets, but they are solutions for the same problem.)
    You can use the @command{xfontsel} program to check which choices you have.

I like it.

Still one nit to pick:
! @item registry
! @itemx encoding
! These make up the character set that the font depicts.  Note that this
! is different from MULE character sets.  You can use the
! @command{xfontsel} program to check which choices you have.  However,

I would say "this is different from MULE charsets" rather than "this
is different from MULE character sets".

Related comment:

I wanted to add some advice about finding out a charset, but no luck.
It's a shame that (at least in XEmacs) there's no convenient way to do
M-: (charset-registry (char-charset (char-after (point)))) RET.  (We
don't even have a `describe-charset', for shame!  Maybe GNU Emacs
does, though.)  Also, it doesn't really give an immediately useful
answer (it's a regexp).  I'll put it on my list, but thought I'd throw
it out in case somebody knows how to do it already.

Re: Setting font to Lucida Grande on Mac OS X

[Luc Teirlinck]

The patch below incorporates the latest suggestions made by Richard
and Stephen.

It also includes some further changes.  

It points out that both font nicknames and XLFD's are
case-insensitive.  It also clarifies that wildcards can only be used
for XLFD's, not for nicknames.  (At least not in the situations we are
describing.  Certain Lisp functions _do_ allow wildcards in
nicknames.)

Also the sentence:

  By default, Emacs displays text in the font named @samp{9x15}, which
makes each character nine pixels wide and fifteen pixels high.

is obsolete since Emacs 21.

I listed:

-adobe-courier-medium-r-*-*-*-120-*-*-*-*-iso8859-1

as the default used by Emacs (under X), because that is the first font
tried by `x-create-frame' and in a fully uncustomized Emacs, that
choice does not seem to get overridden, at least not under X.  Emacs
does seem to use different defaults on other operating systems, so I
mentioned that the default only applies under X.

Any comments on this?

No, that was a mistake of mine.  Wildcards in nicknames are allowed.

Re: Setting font to Lucida Grande on Mac OS X

[Luc Teirlinck]

One more remark about (emacs)Font X:

I do not know whether it would be useful to include the little extra
paragraph below starting with "Note that if you use a wildcard pattern
on the command line,..." or whether that is redundant given the two
examples above it.  Note that this is tricky.  For instance if you use
bash and the `nullglob' shell option is not enabled (it is not by
default) then bash leaves any pattern that matches no file unchanged.
Hence the user could easily get the impression that quoting is
unnecessary, because most of the time it is not.  With `nullglob'
enabled (as I do) bash replaces a pattern that does not match any file
with the empty list and failing to quote _always_ leads to trouble.

Relevant excerpt with proposed extra paragraph:

Here is an example, which happens to specify the font whose nickname
is @samp{6x13}:

@smallexample
emacs -fn \
  "-misc-fixed-medium-r-semicondensed--13-*-*-*-c-60-iso8859-1" &
@end smallexample

@noindent
You can also specify the font in your @file{.Xdefaults} file:

@smallexample
emacs.font: -misc-fixed-medium-r-semicondensed--13-*-*-*-c-60-iso8859-1
@end smallexample

  Note that if you use a wildcard pattern on the command line, you
need to enclose it in single or double quotes, to prevent the shell
from accidentally expanding it into a list of file names.  On the
other hand, you should not quote the name in the @file{.Xdefaults}
file.

The default font used by Emacs (under X) is:

@smallexample
-adobe-courier-medium-r-*-*-*-120-*-*-*-*-iso8859-1
@end smallexample

Re: Setting font to Lucida Grande on Mac OS X

[Luc Teirlinck]

I am afraid that my previous patch may have contained claims that are
only valid for my own screen resolution.  (I do not believe that the
default XLFD really automatically yields a font that is seven pixels
wide and twelve pixels high, as claimed in my previous patch, in all
setups.)  I include a new patch that also contains the paragraph I
mentioned before, but I could, of course, take it back out if it would
be considered unnecessary.

    !   By default, Emacs displays text in a font which makes each character

I don't think that is true.  The default font seems to have the same

It depends on the screen resolution.  I already corrected this in the
latest patch I sent.  I believe that the new description of the
default as a "twelve point Courier" should be generally valid, at
least under X, as long as the font is available.

I believe it would be better to add a parenthetical remark to the
first line of my patch:

  By default, Emacs displays text in a twelve point Courier font (when
using X).

On Mac OS X `Monaco' seems to be the default and I believe that on MS
Windows a 10pt font is used.

The first sentence seems to imply that wildcards are so unreliable
that you should never use them.  It is clearer to say

      However, matching is
     implementation-dependent, and can be inaccurate when wildcards match
     dashes in a long name.  For reliable results, supply all 14 dashes
     and use wildcards only within a field.

That's a good clarification--please do add it.

No, it's not.  On some platforms, wildcards that match dashes _are_ so
inaccurate that you should never use them in production code.  Luc
gave an example.  However, it may be convenient for interactive or
one-shot code use, or if it works in an init file.

The second sentence is a distinct improvement (especially as it
implies partial matching in a field, which often is useful, such as
...-jisx0208*-0 to catch names which specify the year of the
standard), but I recommend that the first sentence be left as is.

I believe the difference of opinion is limited to:

"often inaccurate" (Stephen's version) vs "can be inaccurate"
(Richard's version).

I believe that we all agree with what is meant to be communicated,
namely:

1.  It is OK to try out, say:

M-x set-frame-font RET *-courier-medium-r-*-14-*

Why type fourteen dashes if you can get what you want with the above?
(This works for me.)

2.  If you do

M-x set-frame-font RET -abisource-courier-bold-i-normal--17-*

and get the error message:

Font `-abisource-courier-bold-i-normal--17-*' is not defined

(as I do), then this does _not_ mean that there really is no such font.

In fact, after supplying the fourteen dashes I get the font:

-abisource-courier-bold-i-normal--17-135-90-91-p-100-iso8859-1

3.  Always supply fourteen dashes for Elisp code, except when only
    meant for personal use.  All XLFD's I found in the Emacs
    source code actually adhere to this rule.

To me, both versions suggest 1-3 above, even though Richard's puts
somewhat more emphasis on (1) and Stephen's on (2) and (3).  To me the
difference does not seem terribly big.  My patch currently contains
Richard's version, but I will wait at least 24 more hours before
committing it, so everybody can make further comments.  (Of course,
further changes can also be made after I commit.)

Sincerely,

Luc.

   -abisource-courier-bold-i-normal--17-135-90-91-p-100-iso8859-1

Actually, I should have used (frame-parameter nil 'font) instead of
simply copying from the  C-u C-x = output.

The frame's font I got was:

-abisource-courier-bold-i-normal--17-123-100-100-p-0-iso8859-1

Re: Setting font to Lucida Grande on Mac OS X

[Luc Teirlinck]

Sorry, I had the wrong thing in the kill ring:

-abisource-courier-bold-i-normal--17-123-100-100-p-0-iso8859-1

was xlsfonts output.  

(frame-parameter nil 'font) actually returned:

-abisource-courier-bold-i-normal--17-123-100-100-p-100-iso8859-1

All of this makes mo difference as to the original points, however.

Sincerely,

Luc.
