Two questions

[Frank Winkler @home]

HI there !

I'm just playing around with my programming modes - I use them with both 
emacs and xemacs. After exchanging the "*-mode.el" files it seems obvious 
that xemacs' syntax highlighting is not configured there: emacs inherits 
indention but doesn't do highlighting. It that xemacs-only or where do I 
have to set this?

And is there an enhanced "auto-fill-mode" which doesn't just reformat a 
single line but keeps an entire paragraph trimmed? This would be convenient 
for editing plain text files.

TIA

What kind of modes? Selfwritten? What modes? Identation configuration is not
done allways in the same way.

Both emacs and xemacs come along with support of all kinds of programming
modes.  Take a look at the info docs.

For plain text files see "M-q". C-mode supports M-q for identing whole blocks
the right way.

ESC q runs the command fill-paragraph
   which is an interactive compiled Lisp function in `textmodes/fill'.
(fill-paragraph ARG)

Fill paragraph at or after point.  Prefix ARG means justify as well.
If `sentence-end-double-space' is non-nil, then period followed by one
space does not end a sentence, so don't break a line there.
the variable `fill-column' controls the width for filling.

If `fill-paragraph-function' is non-nil, we call it (passing our
argument to it), and if it returns non-nil, we simply return its value.

If `fill-paragraph-function' is nil, return the `fill-prefix' used for
filling.

At the moment, I'm talking about the default modes (C, Perl, etc.) and my 
attempts to customize them. But I didn't find the code which recognizes the 
commands and sets the colors; is this hard-coded?

Cool stuff! :) Didn't know that - but is there a way to do this dynamically, 
without explicitly triggering a command? The dumbest mail editor can do that 
so I'm sure emacs can ...

type M-x auto-fill-mode.  now, you're comments will auto-wrap when you type 
a whitespace after the fill-column.  type C-u 7 2 C-x f, to set the fill-
column to 72.  good luck.

As I mentioned, "auto-fill-mode" is _not_ what I want as it only reformats 
one line and only after I put an additional white space at the end. What I 
want is what most stupid text editors do in "word wrap mode": just reflow 
the paragraph when something is inserted or deleted.

refill.el comes with recent Emacsen (though I'm not sure if it's in
21.2 already, maybe only in the development version), and then there
is maniac.el.  Both hit M-q for you.

Cool! And when do they do so? Do they also work with 20.6?

I don't know about refill, but maniac should.  They hit M-q "often
enough" -- whenever you change something.

Nope, like allways in Emacs: You can modify nearly everything to fit your
needs. Check the info docs for "font-lock".  Font-lock-mode is activated for
example globally with

    (global-font-lock-mode 1)

Take a look at the documentation of auto-fill-mode. This is somehow automatic
like that what M-q does.  Take a look at "C-x ." (set-fill-prefix) and "C-x f"
(set-fill-column).

Ok, "font-lock-mode" seems to be a good trace. If I enable this mode, my 
Perl program gets fontified. But I still don't understand why and how. The 
word "perl" doesn't appear in font-lock.el.
So where exactly is the keyword-color mapping defined? Why is this not 
coupled to perl-mode.el?

After some more fiddling: hilit19.el seems to be the interesting point.

Re: Two questions

[kgold]

Most experts say that hilit19 is obsolete.

My understanding is that there are standard names, like
font-lock-comment-face, which are shared by all modes.  If you look at
cperl-mode.el, you will see the faces used there.  The default values
are defined in font-lock.el.

You're right. But why doesn't "perl-mode" force "font-lock-mode"? OTOH it 
does on some other installations I use, emacs and xemacs.
What's the common/best wy to achieve this for all programming modes? I saw a 
hint in "font-lock-mode" which is in fact a list of modes implying it - that 
might be easier since I don't have to edit all modes. Or should I do it in 
.emacs? And the same question for the text modes: what's the best way to 
force "auto-fill-mode" or even "maniac-mode" ;) for text, i.e. 
2fundamental-mode"?

Sorry to bother you - I've been a happy emacs user for many years but now 
it's time to get in too deep :) ... and to get rid of all the manual 
actions.

TIA

text-mode is not fundamental-mode.  You should basically never use a buffer
in fundamental-mode.

What's the difference? Does the O'reilly book cover all this? The Desktop

I just tried refill.el and it has a strange effect: I can't enter spaces at 
the end of the input! So I have to type the hole text and then insert the 
blanks afterwards (which is actually working and reformatting)? You're

Then something is wrong; refill-mode works fine for me.

What is your emacs version?  Are you using the version of `refill.el'
that comes with emacs, or something you found on the net?

I'm using 20.6 @home since there's no later OS/2 version :( ... and there 
was no refill.el coming with this one so I googled and downloaded it )hint 
from Kai). In the office I have xemacs but dunno the exact version at the 
moment.

Do I perhaps need an older refill.el?

Because it would be funny to have colors in Perl code but not in C
code (say).

See the user option global-font-lock-mode.  If you turn it on, both
Perl and C (say) will be colorful.

Don't use that.  It's outdated.  Use font-lock instead.

You got it backwards...  Look for font-lock in perl-mode.el or
cperl-mode.el depending on which one you are really using.

Perhaps you are looking for the faces that are being used:

(defvar cperl-tips-faces 'please-ignore-this-line
  "CPerl mode uses following faces for highlighting:

  `cperl-array-face'		Array names
  `cperl-hash-face'		Hash names
  `font-lock-comment-face'	Comments, PODs and whatever is considered ...
  `font-lock-constant-face'	HERE-doc delimiters, labels, delimiters of...
  `font-lock-function-name-face' Special-cased m// and s//foo/, _ as

I'm guessing you are wanting to customize the colors of the various
faces...

Basically, I want to understand how it works. Then I may think about

Emacs comes with two major modes for editing Perl code.  One is
called Perl and the other is called CPerl.  CPerl is based on an old
version of c-mode.el, hence the C.

CPerl has more features, I think.

cperl-mode is an alternative perl support mode that's generally more 
aware of the harder constructs ( here docs, qw/qq operators, regexps 
than perl mode ). It ships with emacs, but I generally grab the 
latest copy from the external maintainer (Ilya Zakharevich) if it's 
more recent than the bundled version.

Two questions....

[Urban Gabor]

Hi,

I have two questions....

1. I would like to set up an Emacs-variable, that stores the
contents of an environment variable. The reason is, tha I
want to insert the $(HOSTNAME) into edited files with one
keystroke... 

2. I generaly do C/C++ and Perl editing with emacs. It would
be very convenient to ha a generic macro, which insert an
empty comment in the code.  My problem is, that the formar
of the comment is dependig on the programming language
(mode) you use. Is there a genereal solution?

Thanks in advance...

You can use:

,----[ C-h f getenv RET ]
| getenv is an interactive compiled Lisp function in `env'.
| (getenv VARIABLE)
| 
| Get the value of environment variable VARIABLE.
| VARIABLE should be a string.  Value is nil if VARIABLE is undefined in

(setq lisp-variable (getenv "HOSTNAME"))

But why not just call (getenv "HOSTNAME") in the function?  Or use
(system-name) which returns the host name?

If I understand Urban correctly, he wants to insert a new comment block -
like say some header text - he does not want to know how to (un)comment
existing lines etc.

Meaning if I'm in C mode I want to say "M-x insert-my-header" and it does

// Filename: 
// Date started:

but in Perl mode it does

# Filename:
# Date started:

At least that's what I've wished for a while. Thought I'd learn enough elisp
to write a function to do that. But when is the question!

Re: Two questions....

[Kevin Dziulko]

I do this all the time.  I've put some standard company headers into files 
(header.c, header.pl, etc.) and then just use C-x i to insert the file at 
the current point.  This works well for pre-existing files.  You could 
also record a simple macro and bind it to a key.  I also use auto-insert 
so I can have standard templates for any new *.c or *.pl files I create, 
which will then automaticlly contain the standard headers.

In any particular mode this is given by the value of comment-start.

(insert comment-start "Filename:"  comment-end "\n")

etc

You  may  need  to  use   a  different  table  for  comment-start  and
comment-end.  For  example, in emacs-lisp-mode,  comment-start is ";",
but generally  you want at least  two semi-colon to  avoid sending the
comment on the  right, particularly for such "header"  comment. In the
case of c++-mode, you get "// " but you may prefer "/* "...

But that's the principle.

And maybe you want/need extra spacing as well.
This is all taken care of if you use

   (comment-padright comment-start comment-add)

and

   (commend-padleft comment-end comment-add)

He explicitly said "empty comment".
Go to an empty line and hit M-; and you get an empty comment.

Two questions

[Perry Smith]

[-- Attachment #1: Type: text/plain, Size: 552 bytes --]

I’m using the nightly build from EmacsForMacOS because I want the XDG_CONFIG_HOME change that went into emacs 27.

Q1: When is this scheduled for release so I can stop using the nightly build?  (Mostly just curious.  The nightly is working ok.)

Q2: I just had emacs die on my Mac.  Just *poof* and its gone with the message "if I want to restart ...".  Should I try and send this information into the maintainers and if so, how would I do that?  What files will be useful to them?  Do I send it to the EmacsForMac guys or the GNU emacs guys?

No idea.  The pretest of Emacs 27 should start shortly.

Use the "M-x report-emacs-bug" command to collect and report all the
details you can gather about this, and send the report via email to
the address generated by the command.

You could try looking in the system logs for information that could
help investigate the problem.  Modern systems generally have some
facility of saving important information about any application
crashes, but the details depend on the OS, and I don't use macOS, so I
cannot tell you the details of where that information is on that OS.
