Defun Self Documentation

Defun Self Documentation

[Christopher Dimech]

When using defun, can one include a Self Documenting string or is
Self-Documentation only applicable for interactive functions?

(defun Gdn ()
   "Description"
   Body ...
)

No need to be interactive.

Minor nit: convention in Lisp is

  (defun Gdn ()
     "Description"
     Body ... )

i.e. closing parens don't get a line of their own. Readers will
thank you :)

Don't people find it tough to immediately figure out which bracket closes
what?  But if readers will thank me, I would certainly comply.  I come from
the C-Language as is evident.

Yes to last (I do, too, mostly). For the parens, there's your favourite
editor.

People are not authoritarian around here, and personally, I do hate
authoritarian style, so I won't complain if you use another style.
But conventions help in communication, thus my hint.

Ask Emacs: `C-h f defun'.

,----
| defun is a Lisp macro in ‘byte-run.el’.
| 
| (defun NAME ARGLIST &optional DOCSTRING DECL &rest BODY)
                                ^^^^^^^^^
| 
| Define NAME as a function.
| The definition is (lambda ARGLIST [DOCSTRING] BODY...).
| See also the function ‘interactive’.
| DECL is a declaration, optional, of the form (declare DECLS...) where
| DECLS is a list of elements of the form (PROP . VALUES).  These are
| interpreted according to ‘defun-declarations-alist’.
| The return value is undefined.
`----

That doesn't explicitly tell you that DOCSTRING is the
doc string _for the function_ you're defining, but one
might guess that.

1. `C-h i m elisp', to visit the Elisp manual.
2. `i defun', to go to the doc about `defun'.

There you see this, about the optional doc-string arg:

 DOC, if present, should be a string specifying the function’s
                                                ^^^^^^^^^^^^^^
 documentation string (*note Function Documentation::).
___


Ask Emacs.

Re: Defun Self Documentation

[Christopher Dimech]

I know many are not authoritarian, but as I will be releasing the code,
the whole purpose is for the form to be useful and convenient for users.
I don't see it difficult, otherwise I will ask for people's view.

Christopher

No.

Turn on `show-paren-mode'.

See also option `blink-matching-paren' and the
other `blink-matching-paren-*' options.

Double-click `mouse-1' on a paren, to select it,
its match, and the text between them.

`C-x C-x' bounces the cursor from end to end of
the region.

If code is formatted normally then you can
pretty much count on the ))))) at the end of a
sexp to balance what you'd expect.  Otherwise,
someone (e.g. you) would already have fixed that.

There's zero reason to put an opening or closing
paren on a line by itself, unless you want to
indicate something specially or add a comment in
a particular way.

`C-M-q' indents an entire sexp (e.g. a defun) in
a conventional way.  It, `TAB', and other keys
know Lisp syntax.

I don't see why that would be important information.  The important
information is to know whether an expression is "inside" or
"next/outside" some other and the indentation already gives you that
information.

Then you have languages like Haskell/Python where you don't even bother
writing the closing paren/brace ;-)

I was hacking Emacs' configure.ac earlier today. I really wished there
was a better functioning identation and paren-highlighting mode. For
some reason whatever mode is activated in configure.ac, it didn't really
understood the ']' and ')' in some places despite them being correct.

Perhaps there is enough reason for some improvement in indentation and

[ Not sure how this relates to the earlier discussion of defun's
  docstrings or placement closing parens, but in any case:  ]

This is 100% under the control of `autoconf-mode`, so that's where
improvements need to be done for that.  IIRC it's not easy to make it
work well reliably because of the "two-level" nature of the language
(IIRC it's a layering on `m4` on top of `sh`), but currently there is no
auto-indentation at all in that mode, so there are plenty of
low-hanging fruits.

My impression: parens are for code editing, for making it easy to write
syntactically correct code.  And as it has been mentioned, Emacs makes
that easy by providing highlighting and paren moving commands etc.

For reading (by humans) indentation is more helpful.  Indentation more
or less directly reflects paren depth.

And to make code even more readable, some people prefer to use
`rainbow-delimiters'.  I guess you would like it.

Michael.

Re: Defun Self Documentation

[Christopher Dimech]

Yes I could like rainbow-delimiters.

Have installed it. Do you know how I can set
rainbow-delimiters-depth-N-face in my init .emacs.

I can understand the problem. Here is short advise:

- (setq electric-pair-mode t)  ;; This will give automatic () instead of only (
  and it will work with [] and "", this helps to make sure what is closed

- highlight matching parenthesis in menu and save options, that
  will give you flashing parenthesis and you will know what you
  are closing.

- additionally you may see in minibuffer also first part of the
  list that you are closing

Re: Defun Self Documentation

[Emanuel Berg via Users list for the GNU Emacs text editor]

When writing a docstring to a function make sure all the arguments
appear, all in UPPERCASE, and in the same order they are passed to
the function.

Use this to verify:

(require 'checkdoc)

(setq checkdoc-permit-comma-termination-flag t)

(defun check-package-style ()
  (interactive)
  (let ((msg "Style check..."))
    (message msg)
    (checkdoc-current-buffer t) ; TAKE-NOTES
    (message "%sdone" msg) ))
(defalias 'check-style #'check-package-style)

That's what `show-paren-mode` is for. :-) You'll only really need it when
editing existing code, however. For writing code, you should use something that
keeps parentheses balanced (I use `paredit-mode' myself, but there are other
options), and when reading code, you should mostly ignore the parentheses and
focus on the indentation.

This comes to mind:

It's rude indeed, but see his "apology" mail on Sat, 29 Aug 2020 14:52:36

The reason for why the current default value is bad: It creates a disconnect
between the user action (moving point) and the observable result (paren
highlight).

Sorry, I'm not prepared to ignore people who publicly smear the names
of others with profanities.  Those people should be prepared to have
their names publicly smeared as well.

Thanks for explaining your reasoning, but let's not forget that
setting that to zero has a downside: if one types fast, it will slow
down redisplay by delaying the response to the typing.

Works perfectly for me, for many years, FWIW.  But of course, this is
personal, which is why it is a user option.

One can do what one wants, but doing what one wants does not mean taking
it to any level of irresponsibility.  Within Gnu we are in the civillised
world, irrespective of which burg people spring from.

Eli is quite correct.

There is less work to do because it happens 0.125 seconds later?

I never noticed any slowdown.  Maybe it's mode-specific, some modes are slow at
finding the match?

Sure, but we were talking about the default, and the 0.1 seconds is an actual
scientific result.

No, because with zero value it happens immediately, and the extra work
required to show the overlay will slow down Emacs.

The display of the overlays to show the matching parentheses works
with an idle timer, and that value is the amount of time Emacs should
be idle before the parentheses are highlighted.  If you time fast,
Emacs will never be idle for that much time, so the parentheses will
not be highlighted while typing.  If you set the value to zero, the
parentheses will be highlighted no matter how fast you type, so Emacs
becomes less responsive to your typing.

I'm not sure the 0.1 number is relevant to this feature.  We are not
talking about the reaction time, we are talking about the shortest
time that indicates the user stopped typing.

It all depends if the user would like to get the highliting every time
the cursor gets ta a parenthesis. It is therefore  understandable
not wanting highlithing contiually.

A solution would be a keybinding that cycles, so the hightlite can be
enabled when required.

That's correct only if you assume that everyone behaves in a rational way. 
There are people with psychological disabilities, who sometimes do not 
behave rationally.  One particularly impressive disability is for example 
Tourette's syndrome.[1] The best thing you can do is to not take what they 
do and say seriously/literally, IOW, to take what they do and say with 
many grains of salt.  Of course all this is more difficult to perceive 
with people who behave irrationally only at times, and is also more 
difficult to perceive on a mailing list.

That depends on how administrators run the project.  Not all are so understanding.
Have you never worked in a serious job before! Administrators are entitled to
reject anybody who cannot function well in a society.  Still, I would not argue
that Emanuel Berg can offend anybody when writing on his own web pages.

That's immaterial.  I've asked to remove the obnoxious slander.  It is
an easy thing to do even if one doesn't understand why or doesn't
agree.

I will wait for 3 days for Emanuel to remove that, before I take the
action I promised to take.

Indeed ;-)
But I wonder why we'd recommend other users not to use lexical-binding
in their `init.el`.

Because the defun special form didn’t work properly in lexically bound contexts.
But since 24.3, the problem with the symbol counter was resolved, it is no longer
a good advice.  People can use it without any harm.

I fail to see the connection.  The restriction of `defun` in lexical
context was very minor, only affected rather unusual circumstances
anyway, and could very easily be circumvented.  And I fail to see why it
should have affected init.el files more than others.

Let should bind to variables only, but it wasn't.  Nevertheless, the recommendation

Yeah ... in practice that's what it is. Some damage to my nervous

Eli, you being a crybaby trying to defend the Emacs turf against
one person writing mails on a damn ML ... it only proves my point.

In my daily life, I go to the bike shop, everyone is "Oh, Manny",
I go to the tree house, everyone is "Oh, Manny", I go to the
brewery, everyone is *hiccup*, but I go HERE, people are always
trying to tell me, I'm no good, blah blah blah.

Eli is old hands at that. When I came here, ~15 years ago, one of
the first things I wrote was this [1]. Yet there were many flame
wars involving Eli, Juanma, and a bunch of other negativist lamers
I don't remember, who critizised everything I did - just so many
people (not everyone) trying to get me to leave...

Today, we have a bunch of guys asking questions, some of which
implies (I might be wrong, but that's how it looks, TBH) they have
no programming experience whatsoever. They ask questions and it is
like a contest in patience, everyone (almost) is trying their
hardest not to loose their temper and speak their minds which would
be soo embarrassing dear God :$

Again, when I came, I wrote the below Elisp. Now, ~15 years later
Eli still tells me I'm not good enough and can't change the
original values of damn Emacs options without explicitly
stating why. It is so ridiculous.

But Eli, guess what, two things, 1) you couldn't defend your little
turf from me then, and you cannot now, I just DON'T BELIEVE YOU,
I KNOW what I can do with a computer, and I can do whatever the
fuck I want to it, including your little turf program; and 2) if we
pause to take a deep breath, why do you think, when I go to the
bike shop, to the tree house, or to the brewery, there is not
a single little punk fucker to challenge me anywhere? are you the
only punk fucker in the world with a turf to defend? hardly! so how
come you think I never meet any Elis face to face?

Yeah, I don't know if you are speaking generally here, probably,
but as for me, I don't have any syndrome, I have a damage which
I sustained when I was 32~32 years old. Like I said, there was
a long time I could keep it apart but now the sane and the insane
(if you will) have melted into ONE person so even tho it can
influence in many ways and most definitely is I still don't want to
blame it.

When you refuse to learn from comments by others on your code, you are
only hurting yourself, in the short and in the long run.  Adding
ad-hominem attacks doesn't change that basic truth.

Hopefully, others have read those comments and will draw their own
conclusions.  It is for them that I wrote those comments in the first
