[patch][org-entities] More symbols

[-- Attachment #1: Type: text/plain, Size: 939 bytes --]

Hi,

This patch adds some general interest(?) symbols to org entities that
otherwise lived in my init file.

1. I don't know how to easily check whether a glyph is supported by
   Latin 1, so Latin 1 entries correspond to the ASCII equivalent.

2. HTML symbols have been tested in Firefox.  In a few cases I
   couldn't find a pretty name (like "π") in which case I've
   supplied the unicode number (like "&960;").  Is that OK?  (E.g. can
   Org produce non-uft8 HTML?)

3. In LaTeX the symbols are mostly defined in amsmath, except coloneqq
   and eqqcolon which requires something like mathtools or kpfonts or
   possibly unicode-math.  Is that OK?  I also fixed some
   inconsistencies.  E.g. loz was loaded diamond even though loz is
   defined in amssymb and "~" and "\tilde" produced different results
   (the latter produces the irritating "\~{}" often observed among
   (social science?) university professors...).

Subject: [PATCH] More org-entities.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* org-entities.el (org-entities): Add support for ell, imath,
jmath, varphi, varomega, varpi, aleph, gimel, beth, dalet,
cdots, S (§), dag, ddag, colon, therefore, because, coloneqq,
eqqcolon, triangleq, leq, geq, lessgtr, lesseqgtr, ll, gg,
prec, preceq, preccurleyeq, succ, succeq, succurleyeq,
setminus, nexist(s), implies, impliedby, iff, diamond.
Changes loz and tilde.

In LaTeX these symbols are mostly defined in amssymb. coloneqq and
eqqcolon require kpfonts or mathtools or similar in LaTeX.

Use "C-u C-x =" on the character and look at "preferred charset"

I think it can: see `org-html-coding-system'. It may be wiser to avoid
these symbols altogether.

Any additional package needed must be added to
`org-latex-default-packages-alist', which means that the package will be
loaded in every LaTeX export. So, this is clearly not OK for packages
like "kpfonts".

As a rule of thumb, I think we should avoid requiring new packages for
org-entities.

This one is LaTeX specific, it may be more appropriate in

Ditto. Also, the LaTeX code looks wrong.

Didn't you forget a "\not" in LaTeX entry?

Is is really needed? There are already two entities producing the same

I agree.  I'd wish we could cut down on some of these darn symbol
packages!  latexsymb should be fairly easy to get rid of.

We also have stuff like le and rarr, which is clearly HTML-specific.
An important part of entities (IMO) is the unicode display in-buffer.

impliedby, iff and implied are recommended since they use correct
spacing.  They are, however, defined in amsmath, which isn't loaded,
although perhaps it should be.

I'll prepare a reduced patch.

There are many X-specific entities. . .  E.g. lArr is html specific.
One important feature of entities is that unicode symbols can be
displayed in buffer.  If you feel strongly about it, I can remove
them.

It's easy to remove the decency of latexsym as it only defines a very
limited number of symbols (see texdoc latexsym).  Using amssymb
symbols will even look better IMO, but check this document:

#+BEGIN_SRC Org
#+latex:\Huge
  - [ ] x
  - [-] x
  - [X] x
#+begin_latex
  \begin{itemize}
  \item $\square$ x
  \item $\boxminus$ x
  \item $\boxtimes$ x
  \end{itemize}
#+end_latex
#+END_SRC

Obviously, it requires the removal of Diamond (my entity patch) and
Box (this patch)

It seems you have a keen interest in latex + org-entities.

(This might be familiar to you.)  

You can do a,

    C-x b *scarath*
    C-x C-m C-\ TeX
    C-h C-\ RET

and pull all the entities that you ever want in a single go (rather than
including them piecemeal-by-piecemeal.)

With some scripting, this pulling can be made less laborious but more
complete.

This is just a note.  Nothing beyond that.

Indeed, I use this in message buffers.  If using unicode-math (a GREAT
latex package) one should even be able to use TeX input style in an
Org buffer.  However, cdlatex + entities is much quicker (on my system
"¨ b" (I've changed default keys) for β versus "\beta").

> With some scripting, this pulling can be made less laborious but more

Would you be able to get the HTML entities?  Nicolas said that Org
"prefers" entity names due to encoding.  I can find the unicode number
in Emacs, but not it's name.  This is often the laborious part.

Why use name when it is easier to use the numerical value?  

Something like &#x2014; should be good for —.  (You can get the code
value by doing the C-u C-x = on the displayed character.)

,----
|       character: — (displayed as —) (codepoint 8212, #o20024, #x2014)
|                                                               ^^^^^^
|   name: EM DASH
`----

----------------------------------------------------------------

I see that the entity names are listed in
http://www.w3.org/TR/xml-entity-names/byalpha.html

----------------------------------------------------------------

Load the above file within Emacs.

  M-x eww http://www.w3.org/TR/xml-entity-names/byalpha.html RET

or 

  M-x browse-url-emacs RET
  http://www.w3.org/TR/xml-entity-names/byalpha.html RET
  
  M-x load-library RET shr RET 
  M-x shr-render-buffer RET

Write the resulting buffer to an Org buffer or a text file. Then C-s for
the unicode codepoint, C-a to get the entity name.  You are done.

Don't know.  Here's a quote from earlier.  I personally didn't look
further into it.

Irrespective of encoding?

Right.

Are we having (huge) gaps somewhere worth fixing?
