RTF for emacs

RTF for emacs

[James Freer]

I read some time ago that there was development taking place for providing 
emacs with word processing i.e. formatting iirc RTF.

Is this taking place or has the interest declined. Reading posts a while back 
on 'how emacs can be improved' (or similar header). I was wondering as one 
thing I'd love to see in linux would be a cli RTF editor or graphical. I found 
so many bugs in Abiword and LO-writer that I don't want to use them.

thanks

I'm not aware of any RTF initiatives.  Did you try Org?  It outputs to
odt, html and LaTeX.

Yeah. Question to the OP: Why do you want "RTF"?

For e-mails, Usenet posts, README files, everything
short and neat - plain text will do (is superior,
because it is so easy to deal with for everyone, and so
fast to do so, and so enjoyable to type...).

For the odd very-fancy-looking manual or MS degree
techno-science thesis - LaTeX obviously, which you can
enter plain in Emacs (no need for Org) and
compile.

PDFs are great for advanced documents (with special
notation etc.) and for large documents (e.g., books)
that are expected to be read by humans - documents that
are likely to be printed (and, when done, not expected
to change a lot save for an occasional additional
chapter or so, and typos fixed).

A lot of PDFs shouldn't be PDFs, though (as I see
it). A two-page essay with 4-6 paragraphs and no
illustrations or special notation - why use PDF for
this? Use plain text: faster, lighter, and much easier
for everyone else to use in whatever way they prefer.

HTML for webpages (of course): again type direct in
Emacs (again no need for Org).

If you are ever so lucky as to write a brand-new tool
for some Unix-system - groff (GNU runoff or roff) -
groff to do the man page (saliva in my mouth just
thinking of it). (Also the GNU ancient-empire "info"
tool has a markup system which I'm unfamiliar with.)

Really, what *is* the use-case for "RTF"?

But I'm sorry I can't answer your question - but the
reason I can't is I never saw the need to use it.

What about writing a letter to your bank?  Or writing a short technical
document that has to include diagrams?  Plain text can't really do these
things.  Latex can do these things, but it's complicated.  Whenever I
need to use Latex I have to look at lots of examples from the internet
or the last time I used it.  Since I never write large reports using
Latex it's syntax never sticks in my head.

I use a word processor for these kind of things a present, Libreoffice.  I'd
rather not do that though, it's clumsy.  If I had the time I'd help with
adding RTF editing and/or word-processing to Emacs.

Something I'm considering is using info format.  The info makeup is very
simple (for the GNU manuals it's compiled from sources in a TeX dialect
called TeXInfo, but it can be written directly).  Another possibility is using HTML.

Of course is can with a markup language.

Org-mode[1] is your answer. It can do everything you listed with a simple
markup language.

I never understood the Org-mode hype but it must be
good as so many people talk about it. Is it like a
one-to-many mapping so there is one Org-mode markup and
then it gets you a website, a PDF, whatever, by
generating HTML (and CSS), LaTeX, etc., as an
in-between stage? Is that it? Or what is it? If it is,
how can you trust it?  Won't you scratch your head all
the time thinking, "can Org-mode really write as good

Yes, it is a one to many mapping. However, publishing is only a small
part of org-mode. To quote from the introduction of the org-mode manual:

,----
| Org is a mode for keeping notes, maintaining TODO lists, and project
| planning with a fast and effective plain-text system. It also is an
| authoring system with unique support for literate programming and
| reproducible research.
| 
| Org is implemented on top of Outline mode, which makes it possible to
| keep the content of large files well structured. Visibility cycling and
| structure editing help to work with the tree. Tables are easily created
| with a built-in table editor. Plain text URL-like links connect to
| websites, emails, Usenet messages, BBDB entries, and any files related
| to the projects.
| 
| Org develops organizational tasks around notes files that contain lists
| or information about projects as plain text. Project planning and task
| management makes use of metadata which is part of an outline node. Based
| on this data, specific entries can be extracted in queries and create
| dynamic agenda views that also integrate the Emacs calendar and diary.
| Org can be used to implement many different project planning schemes,
| such as David Allen’s GTD system.
| 
| Org files can serve as a single source authoring system with export to
| many different formats such as HTML, L A TEX, Open Document, and
| Markdown. New export backends can be derived from existing ones, or
| defined from scratch.
| 
| Org files can include source code blocks, which makes Org uniquely
| suited for authoring technical documents with code examples. Org source
| code blocks are fully functional; they can be evaluated in place and
| their results can be captured in the file. This makes it possible to
| create a single file reproducible research compendium.
| 
| Org keeps simple things simple. When first fired up, it should feel like
| a straightforward, easy to use outliner. Complexity is not imposed, but
| a large amount of functionality is available when needed. Org is a
| toolbox. Many users usilize only a (very personal) fraction of Org’s
| capabilities, and know that there is more whenever they need it.
| 
| All of this is achieved with strictly plain text files, the most
| portable and future-proof file format. Org runs in Emacs. Emacs is one
| of the most widely ported programs, so that Org mode is available on
| every major platform.
`----

Here is a very abridged list of it's features:

     http://orgmode.org/features.html

or take a look at the manual itself:

   http://orgmode.org/org.html

The pdf version of the manual is 281 pages long!

Well try it out for yourself and see. There is very fine gain control of
publishing. For example, for LaTeX and pdf:

    http://orgmode.org/org.html#LaTeX-and-PDF-export

and for html:

    http://orgmode.org/org.html#HTML-export

etc.

Hi Robert,

If you are capable of helping to add RTF editing to emacs then you are
surely capable of handling LaTeX :-)  However I'm not clear from your
post how deeply you are into the Emacs world. Do you, for example, know
about Auctex, the LaTeX-writing mode for Emacs? 

My own experience is that learning Emacs and LaTeX is a life-work in
itself, on top of  the need to actually make a living, raise kids etc
etc!  T.E.A., the Tweaking Emacs Addiction, has been the ruin of many.

The answer is to create templates, especially for LaTeX - then just
insert as needed.

1. Letters

There is a good tutorial for producing a letter here:
 
http://www.kindoblue.nl/articles/cover-letter-part1/


Look here for lot of templates

http://www.latextemplates.com/



2. Tech reports with diagrams.

LaTeX can produce amazing diagrams but it is, as you said, complicated. I
tend to produce graphics/diagrams elsewhere and then import 'em.  There
are some good tutorials here

http://www-h.eng.cam.ac.uk/help/tpl/textprocessing/



3. Org mode

Is fantastic and I use it all day and every day. My view would be that if
you want to use it for exporting  LaTeX, you need to have some
understanding of how LaTeX works in order to produce the org templates
you need.

Seems like re-inventing the wheel!   The time might be better invested in
getting a grip on LaTeX.  The template thing has been the key for me.



Good luck!

Definitely! And it is a better project which also
involves a community. If you can't stand
Star/Libre/Open Office and the like word processors,
why try making Emacs into one?

And latex-mode.

Yes! On the other hand it is pleasant, relaxing, you
learn stuff, and all the improvements you make, you
immediately can use and benefit from (even derive
pleasure and pride). Compare this to all the morons
who who spend years on the grandiose MMORPG or
would-be-Quake-killer, projects that will never
complete and from whose activity it is very difficult
to flow anything sensible (and generalizable) to the
outside world.

Emacs hacking is an OCB trap but it is possible to get
out on the other side and have a system you really,
really enjoy (and have mastered, not the least through
the tweak process itself) - but sure, if you don't get
out and is stuck starving in the buffer in-between,
then it sucks.

Ha-ha, "foreground" :)

But that's actually a great idea (not just aa2u, but
artist-mode as well). I have been looking for a way to
do simple diagrams (trees, FSMs and so on) with the
keyboard only (i.e., generate from definitions) - I
have tried with ImageMagick and even Dia, as it uses
XML, so why not edit that first hand?

Answer: Problem with both approaches is that it
required too much back-and-forth
edit-and-check-and-fix-and-check-etc. so it just wasn't
pleasant or efficient (perhaps if you had a dual
monitor/projector and on-the-fly-update it would be).

This seems very interesting!

When I got a cool diagram, how do you propose I embed
it with the LaTeX PDF? I know there is way to include
plain text "as is" - perhaps that's even better than to
first export it as a picture, and then include the
picture? It is certainly more appealing - faster and
smaller.

[Emanuel Berg]

Holy smoke! I was able to do this is zero-time -
compare that to getting intuitive with ImageMagick or
Dia XML! Only problems I had - aa2u translated the dash
in "best-effort" as well (perhaps unavoidable, but very
minor so) - also, in artist-mode, can you grab a side
of a rectangle and move it left-right (or up down)?
Also, when typing, that typically screws up the figure,
so can you make it insert text while simultaneously
eating whitespace at the other end?  Amazing stuff!

I didn't mean RTF especially but rich text able to do basic word
processing including page numbering suitable for basic docs but
without going OTT like LO-writer.

Thank you for suggesting org, html, enriched text but it's not the
same. These days I tend to use google docs for speed, draft in emacs
as text and then import into google docs... that's a pain. I just
vaguely recall something once being mentioned for emacs... does
everything else after all.

I don't know exactly what RTF is is but I take it is
the word processor stuff: fonts, boldface, headers,
etc.

Again, I don't see why not just using a word processor
for people who want that - isn't that what they are
for?

I prefer just typing text, and with markups for the
rare cases it is needed, ..., it is the cooler, faster,
and more powerful approach with few limitations (what I
can see) and all the benefits. It is more pleasant,
which should never be underestimated. The more
relaxation and familiarity with the tools, the bigger
part of the brain can be allocated the qualitative part
of the problem...

Of course, LaTeX does (can do) page numbering
automatically and there are lots of options to it.

> Thank you for suggesting org, html, enriched text but
> it's not the same.

Well, I didn't suggest that (perhaps someone else did)
- I suggest HTML (and CSS) for *webpages* (but created
as markuped text), and LaTeX (likewise) for ambitious,
lengthy documents that are expected not to change much,
and be printed (read by humans), that require
specialized notation (beyond ASCII). And: plain text
for everything else.

Yes... it sucks. The web, man. Back to the days when

Thanks, but I haven't given up just yet of including
the Unicode right into the PDF - just imagine how cool,
with no image files whatsoever to burden you!

So just now, I sent the following to comp.text.tex -
let's see if they can solve it!

(post begins here)

I just learned about Emacs' artist-mode on
gnu.emacs.help, which I used to draw two
diagrams. Then, I used a clever tool called
aa2u (ASCII Art To Unicode) [1] to make solid lines
out of the dashes and all that.

Examples: with [2] and without [3] Unicode.

Now, in the LaTeX source [4] I put this:

\usepackage{alltt}
%% ...
\begin{alltt}
  \input{tree.txt}
  \clearpage
  \input{multicore.txt}
\end{alltt}

And the result looks like this [5] (at page 2, right
after the TOC).

Question is, is there a similar way to include not the
ASCII, but the UTF-8 versions of the diagrams? I tried
the same way, only it got stuck on pdflatex on the very
Unicode.

I know I can make pictures of them but I like the idea
of just having those as text, and just inserting them
(faster update, and no in-between file - minimal
overhead).

xetex (xelatex) and luatex are intended to solve this.
I need to say however...
After 3 days of struggling including some 1 G of downloads and setup fiddling
I hear that it may not be (quite) working.

On the one hand xelatex does not work, classic latex works
On the other this is freakin 2014 do we still stay in 1980 and write

I do my diagrams in a self-invented semi-human-readable markup
language[1], which is then post-processed using Python scripts into
Graphviz[2] graph description language, which is then further rendered
into any image format you like (notably PNG, SVG, PDF and EPS). My
format of choice happens to be SVG, which I can conveniently view in
my web browser, print out without any loss of quality, and/or embed in
an HTML page.

http://sf.net/plantuml/ for a Java-based alternative
[2] http://www.graphviz.org/

One could write Graphviz directly but it is too low-level and verbose.
I view it as a graph assembly language and build higher-level tools on
top of it.

Yes, it involves this feedback loop, and it’s mildly frustrating. And
yes, dual monitors help very much.

In my opinion, nohow. PDFs are for getting your article printed, and
that’s becoming more and more irrelevant. Better publish online in
HTML with illustrations in SVG. (But if you must, Graphviz can also
generate Encapsulated PostScript which LaTeX will happily include in
the PDF.)

I don't think so. Just think about the computer-book
industry! A lot of thick manuals are lovely to print
(and heft) and then have by the computer to look up
things. Books (physical) are much more relaxing to
read, and involves less eye-strain, and they work on a
different mental plane - when at the keyboard, you (or
I perhaps I should say) want to be the fighter pilot,
active, overconfident, focusing on the problem, trying
new things, attacking from different angles. With the
book (perhaps on a train station) you are the
helicopter pilot, modest and low-key, trying to grasp
the whole scope of things - like 600 pages of C
programming - you sure didn't think of that when you
perfected a couple of nested for loops to nail an
algorithm... Also, reading more general books (perhaps
the autobiography of Wozniak, which I today learned is
available as an audio book) - that stuff is great for
culture, and very enjoyable.

> Better publish online in HTML ...

Well, LaTeX is much more expressive (beyond any
comparison, really) and it looks the same everywhere.

Other than that, interesting post. Get back to you on
that home-crafted tool of yours.

I think \alpha is better. I can't see those other chars
for starters and I'd like to be sure everyone see what
I write. Also, how did you insert them? ("\alpha" takes
zero time to type.)

Only with complicated formulas it might make sense to
have the Greek alphabet as it is - I can't say for the
mathematicians or the HPC professionals or whatever...

No way, ugly and obsolete! There will always be more
excellent C (with !='s) around than ever purist and
neurotic Haskell. But to each his own. (By the way,
some of those chars I cannot see as well.)

Expressive, yes, but that should be fixed by developing and
standardizing XML schemas for everything that is not well expressible
in HTML/MathML/SVG.

Looks the same, yes, and that’s a bad thing. The shape of content
should adapt to the reader [both human who does the reading, and
device which is used], not the other way round. On paper, I am ok with
10pt Times and can handle two columns on an A4 page or two A5 pages
side-by-side. On a desktop screen [at least until 4K displays become
widely available and reasonably priced], I want a highly legible 12pt
sans-serif, hinted for subpixel rendering, in a single column of
adjustable width, and no subdivision into fixed-size pages. And don’t
even start with me about tablets and smartphones. (And no, it’s not
reasonable to expect that readers be able or willing to re-render your
LaTeX article for their device capabilities and personal preferences.)

I will credit contributors on the tip jar page, of course.

   Also, when typing, that typically screws up the figure,

This is what the venerable ‘overwrite-mode’ does.

Perhaps *I* should credit *you* in my paper! But then I
suppose I would have to credit Bjarne Stroustrup for
C++, Donald Knuth for TeX, Leslie Lamport for LaTeX,
down to Gutenberg for the printing press... It would be
a massacre.

No, of course I can send the stuff to you when its
done. But you might even more interested in this [1],
namely, how it looks and works in an
xelatex-compiled PDF (instead of pdflatex; xelatex is
in the Debian texlive-xetex package).

Cred to the people at comp.text.tex for helping me with
that.

OK, silly me. Of course. (That, or something to that
extent, is applied by default in the artist-mode, by
the way.)

Yes… not seeing *is* a problem. We are in times of transition...

Inserting α is identical to inserting \alpha – just use tex input method
in emacs

Of course in the long run even this is way too much.

I need one keystroke to type an 'a' 1½ (that is 1-and-a-half if you cant see it)
to type a 'A' — a shift+A chord.  I would expect all standard heavily used
keys to be upto 3-4 keystrokes away. eg the half above is 3 keys:
Compose+1+2. [Ive set compose to the Windows-menu key]

So I can get
αβψδεφγηιξκλμνοπ;ρστθωςχυζ
by typing
abcdefghijklmnopqrstuvwxyz 

if Ive setup my keyboard to switch between greek and us, thus

$ setxkbmap -option "grp:switch,grp:alt_shift_toggle,grp_led:scroll" -layout "us,gr"

Since I am not primarily interested in greek, I of course dont do this

HTML and the Internet is one chaotic hack. LaTeX is a
virtually bug-free, domain-specific programming
language to produce documents.

But it is not even HTML vs. LaTeX (or web vs. PDFs) as
those serve two totally different purposes. (Or should,
at least.)

Yes, this is what I'm saying all along! I don't think
you should read PDFs on the monitor/projector, and
certainly not on "smart"phones - grep the web, you
should get web pages (in HTML), print the 600-page
manual or Ph.D. thesis with techno-science notation -
LaTeX and PDFs.

What you can do with HTML cannot at all compare to what
you can do with LaTeX, and if you could (which you
can't) it would be extremely uncertain if it would work
for half browsers - and some people actually need all
that stuff. (And I don't even like browsers, anyway.)

But I'm the first to say PDFs are used too much and for
information that do not benefit from it at all, and
then it is much better with ASCII or HTML.

Do you type \alpha and it (well) "expands" to the Greek
letter? Like an abbrev? If so, I don't like that, I
like what I type is what I get.

I still think it is much better just to type
\alpha. Faster and more solid. Five years from now, you
still remember it.
