text formating

text formating

[Gottfried]

[-- Attachment #1.1.1: Type: text/plain, Size: 756 bytes --]

Hi,

I read the Emacs manual and made an excerpt of keybindings etc for myself.

I would like to have a text editing of the headings e.g.:
  to increase the font, may be to make them bold.

What options do I have as an emacs newbie?

I would like to use this file regularly, so in creating a LaTex file I 
would always have the LaTex formating visible, which is not so nice.

I don't need to print it for the moment, then through LaTex and 
converting it to HTML etc would surely make a nice printout.

Could I use my "fundamental enriched text" in org-mode? , would I have 
the possibility to increase the fonts of some words and headings e.g.?


The text formating in Emacs is not so easy as I thought.

Kind regards

Gottfried

I'd use org-mode, for me its header lines are sufficiently emphasised
(in colour and in certain Emacs themes also with different fonts and
sizes).

* Header1
** Header2

Structural LaTeX (and Html) commands (\chapter or so) are provided by
Orgs markup language.

"Short range" latex formatting is done with other markup rules, like
*bold*, _underline_, .. , they are not so intrusive as the latex
commands.

For heavier latex formatting you might put them in Orgs latex src blocks
which you can fold to hide the "ugly" stuff.

org-mode's latex export and html export

In my opinion org-mode files don't need extra text enrichment besides
its own markup rules.

I hope you'll appreciate and enjoy working with "pure" text. ;-)

If you're interested I can provide you with real world examples.

You probably wish to have printed representation with increased font,
or bold text, and other markup.

Emacs is text editor, and unlike desktop publishing sofware, it may
visually represent bold fonts, enlarged fonts, but it is not WYSIWYG
or What You See Is What You Get.

You would need to use some processor, to process your markup.

Normally you would use this workflow:
-------------------------------------

1. Edit text

2. Invoke some processor to convert to some other format and file

3. Preview the new file

> What options do I have as an emacs newbie?

You have got Markdown, Asciidoc, Kotl, Org mode, Jemdoc,
reStructuredText, txt2tags, Djot, Wikitext, LaTeX and other options.

> I would like to use this file regularly, so in creating a LaTex file

I understand that. You need something simpler. 

- Markdown can be used to convert to HTML but by using `pandoc' also
  to many other formats, such as PDF

- Asciidoc is more expressive than Markdown, can give PDF and HTML

- Org is Emacs built-in, very easy to learn and expressive

> I don't need to print it for the moment, then through LaTex and

Using Markdown or Org is very simple. There exists already
`markdown-mode'

I use following function to process text with Markdown.

(defun rcd-markdown (text &rest args)
  "Markdown processing"
  (let ((markdown (executable-find "markdown")))
    (cond (markdown
	   (cond (text 
		  (apply 'rcd-command-output-from-input markdown (append (list text) args)))
		 (t ""))
	   (t (user-error "Command `markdown' not available"))))))
	   
And I use 

Discount – a C implementation of the Markdown markup language:
http://www.pell.portland.or.us/~orc/Code/discount/

for reasons that it is more expressive, it provides table of contents
and valid HTML, and is fastest.

Then you could the following preview function:

(defun rcd-markdown-preview ()
  "Preview Markdown."
  (interactive)
  (let* ((output (rcd-markdown (buffer-string)))
	 (file (concat (buffer-file-name) "-MD.html")))
    (with-temp-file file (insert output))
    (browse-url file)))
	
Then you bind that function to some keyy, like C-c a

Then while writing, you only press `C-c a' and browser opens showing
you the HTML.

You could learn here:
https://www.markdownguide.org/

Then you got Emacs Org mode, you can learn it by using Org manual, it
is similar to Markdown with many features.

Enriched text is not for that purpose. it is only text, enriched, and
I guess it was meant for e-mails. But yes, I suppose that it is
possible to extend enriched text to make universal output of it, like
from enriched text to PDF, that should be possible, but such program
does not exist that I know.

> The text formating in Emacs is not so easy as I thought.

Beautiful and highly expressive documents have been made by Emacs,
once you start creating it, it will become easier, as with
understanding and training comes the result.

To make font larger in Org mode you just use:

\large{My text here}


Then you have Asciidoctor:

Asciidoctor | A fast, open source text processor and publishing toolchain for converting AsciiDoc content to HTML5, DocBook, PDF, and other formats.:

I can offer ArchiTeX, a simple system that abuses Emacs/PSGML as
a smart text editor that lets you handle text options (fonts,
list layout etc.) via XML tags, and then, at a mouse click,
converts the document to LaTeX and then to PDF. If you run
a PDF viewer parallel to Emacs, you see what you get.

Please contact me if you are interested.

Do you maybe mean AucTEX?

Or ArchiTex? Where is that?

Hi Jean,

thank you very much for the detailed explanation. It is very helpful.

I don't understand why until now nobody made in Emacs a
WYSIWYG Mode.

It would be so much easier, especially for newbies in emacs.
You could see immeadiately what you changed and what you want.


Kind regards

Gottfried

They did: it's called Enriched mode.

In Emacs, that's `C-h r enriched mode RET'.

By reference from:
https://en.wikipedia.org/wiki/WYSIWYG

In computing, WYSIWYG (/ˈwɪziwɪɡ/ WIZ-ee-wig), an acronym for What You
See Is What You Get,[1] is a system in which editing software allows
content to be edited in a form that resembles its appearance when
printed or displayed as a finished product,[2] such as a printed
document, web page, or slide presentation. WYSIWYG implies a user
interface that allows the user to view something very similar to the
end result while the document is being created.[3] In general, WYSIWYG
implies the ability to directly manipulate the layout of a document
without having to type or remember names of layout commands.

Enriched mode is far from there.

At least user should be able to get same printed representation even
if font sizes are not changed.


So far Emacs cannot print Unicode and smilies that I know.


WYSIWYW, what you see is what you want, used to describe GNU TeXmacs
editing platform.[22] The abbreviation clarifies that unlike in
WYSIWYG editors, the user is able to customize WYSIWYW platforms to
act (possibly in part) as manual typesetting programs such as TeX or
troff.


Maybe that one fits better to Enriched mode, but I do not know good
printing representation for it.

Thank you for the lecture.  I surely needed it.

If you are talking specifically about WYSIWYG printing, then yes, we
still aren't where we should be, especially with non-ASCII text;
patches welcome.  But the OP didn't mention that, so this is not
necessarily what was the issue.

Here is how Enriched Text may become word processor with pleasant
result:

1. Enriched mode, with some addition of font sizes or similar

2. By converting Enriched Text to Pango markup

3. By using Pango markup in Emacs Lisp program

   Pango – 1.0: Text Attributes and Markup:
   https://docs.gtk.org/Pango/pango_markup.html

   Pango Markup:
   https://shinmera.github.io/pango-markup/

4. By using `paps' command, I have made package for it, but it may be
   used by various methods:

   GNU Emacs package: rcd-paps.el:
   https://gnu.support/gnu-emacs/packages/GNU-Emacs-package-rcd-paps-el-76862.html

5. By converting on the fly the Enriched Text to Pango markup

6. By using Pango markup to produce printable documents with `paps'

The above workflow can produce visually pleasant text with all
attributes how Pango markup has it, provided that Enriched mode get
translation to Pango markup.

Could somebody help with making of such package? For me, I do not know
exactly where to start.

Michael how about some power from North?

Most people are from the opposite side of the spectrum, i.e.
text editor, not word processor.

Here is where you should look

  https://www.techradar.com/news/the-best-free-word-processor

In principle, I don't see why Emacs cannot be like that as
well for those whow opt-in on it, but in practise it's an
uphill battle - I don't see us every getting there, for the
said reason, most people who are here or come here do that for
the opposite, the text/programmer's editor side of it.

Jean, what features is it exactly that you miss?

For example, that they have in LibreOffice Writer?

Because, if you focus on those, maybe you have better luck
getting them individually so to speak.

You have sent references to non-free software, so those I can't use. 

There is much better free software in GNU/Linux then those referenced.

Finally there are also those such as What You See Is What You Mean --
like the beautiful LyX. There is TeXmacs too.

LyX | LyX – The Document Processor:
https://www.lyx.org/

Welcome to GNU TeXmacs (FSF GNU project):
https://www.texmacs.org/tmweb/home/welcome.en.html

There is AbiWord and similar others.

But as I have explained, Emacs can be made to print all styles at
least similar, and in colors, how they are on screen, by using
translator program that would translate from Emacs properties to
Pango.

If you know how to provide conclusive reader function, that would
isolate each property, then I guess that would be already something to
start making translation functions to Pango markup.

Printing is already solved with `paps'.

Basically, that is so close, in my opinion.

But one would not be setting up margins, spacing, that all can be done
by using `paps' not Emacs directly.

Font sizes, colors, types, fonts, all that can be translated to Pango.

Search for discount markdown, it has table of contents feature, and
valid HTML, and is fastest.

You can install markdown-mode for Emacs.

markdown is basically used on command line, in shell, like:

echo "## Hello" | markdown
<h2>Hello</h2>

Emacs helps you to make that conversion easily. markdown-mode has
preview already.

Can you install markdown-mode?

I have made functions so I just press single key for conversion.

You can do following:

(keymap-set markdown-mode-map "C-c a" #'rcd-markdown-preview)

You need Emacs 29.1 for that function to work.

I have just tried it, it works well.

Hi Jean,
I installed markdown-mode in Emacs, but I have Emacs 28.2, so I can’t 
set the keymap for C-c a.

I also installed Pandoc and emacs-pandoc-mode

I opended emacs and evoked markdown-mode and it opened my file in 
markdown-mode. So at least it works.

So now there is only the question how to use it.

Kind regards

Gottfried

Then you use:

(define-key KEYMAP KEY DEF &optional REMOVE)

So like this:

(define-key markdown-mode-map (kbd "C-c a") #'rcd-markdown-preview)

> I also installed Pandoc and emacs-pandoc-mode

Pandoc is good for various conversions of documents.

For example markdown to PDF, it can work I guess. I have many
functions for pandoc too.

Good, now just to define key to get preview. Some people make their
notes in markdown. It is more compatible with mobile editors on mobile
devices then Org mode.

I seriously consider using Enriched Mode as it is more visual, just
that I make `paps` work with it.

FWIW - There is no optional REMOVE arg for
Emacs through the latest release (Emacs 28.2).
Perhaps it was added for Emacs 29.

If that's the correct variable for the keymap
you want, just make sure you load the file
that defines that variable (keymap) before
you try to  use that variable

;; if `markdown.el' is the file name:
(require 'markdown)

Hi Drew,

I have got a "markdown-mode.el" file

but I didn’t find a "markdown-el" file.

So if I understand you right,

I have to put this in my init.el file:

(require "markdown-mode)

Am I right?


Kind regards

You have to use single apostrophe:
(require 'markdown-mode)

Yes, right order: load the library, then use it.

Something in your init file doesn't _parse_.  Most likely you're missing a right paren or something.  Use `M-x check-parens' in your init file.

You can put (setq debug-on-error t) at the start of your init file, or customize it to t.

You can start Emacs using the switch --debug-init, as the error msg suggested.

See also https://www.gnu.org/software/emacs/manual/html_node/elisp/Error-Debugging.html
___

In general, when your init file has a problem, consider _bisecting_ it, to find the culprit.  Bisecting is a binary search - it's fast.  You can use `M-x comment-region` to comment out 1/2, then 1/4, 1/8, 1/16,... of your init file.  With C-u it UNcomments one level of commenting.

thanks for helping me.
Now it works.
and I learned a lot.

How do you underline some words?
I don’t know how to do it?

In Org, it's _underline_. In ASCIIDoctor it is (I think!) <u>underline</u>

In real life, you take a pencil... ;-)

> How do you underline some words?
> I don’t know how to do it?

1. Some modes use markup of some kind, whether HTML, XML, TeX/LaTeX, Org, or whatever.  Check the doc for such modes, for what markup to use to get the effect of underlined text.

2. Otherwise (i.e., more generally), you use Emacs faces to change the appearance of buffer text, either by applying text properties (e.g. property `face') to characters in the buffer or by applying overlay properties (e.g. property `face') to buffer positions.

One attribute for a face is `underline'.

Example: you use `M-x customize-face RET font-lock-comment-face RET', then in the Customize buffer you (show and then) change the value of attribute Underline to On, then change the State of the face for the current session to accept your change (edit): Set for current session. That changes occurrences of face `font-lock-comment-face' so that text with that face is underlined.

3. In enriched-text mode, you can use `M-o u' to apply face `underline' to any text.

Read the manual (`C-h r'), about faces, font-locking, and faces in enriched text (https://www.gnu.org/software/emacs/manual/html_node/emacs/Enriched-Faces.html).
