Feature suggestion

[Marius Nita]

Hello,

I have a few thoughts on a possible Emacs feature. This might already exist,
but not to my knowledge.

I like the desktop feature very much, especially for my laptop, since I have
to shut it down a lot. However, I found that things can become fairly
cumbersome if I am working on several projects simultaneously. I usually close
the files for one project, and open the files for another. There is no quick
way to switch between projects. Keeping both projects open is also cumbersome.
I was thinking of a multiple desktop environment, where each desktop can be a
project. The desktops would have names, and you could load them, save them,
and discard them like the current desktop feature; only you would have
multiple ones, with different names. Maybe there could be a command line
option to load a certain desktop (emacs --load-desktop project1), and from
within emacs, you would call the desktop- functions with a name parameter.

Thanks,
marius

You can do this at present, surely? Just save different desktop files in
different directories. To load the one you want, either start Emacs in the
appropriate directory, or execute a cd inside Emacs. Then load the desktop
with the command (desktop-read). To clear things out before loading another
desktop, there is the command desktop-clear (although it kills most
buffers, not just the ones loaded in from the desktop file).

desktop-menu.el allows multiple desktop files in the same directory:

Dear community,

since I used Scrivener (Windows Beta) quite a while I'd love to have 
more of fletcher penny's multimarkdown (or MMD- like Syntax) integrated 
in orgmode to make it more versatile. Sadly I am not a lisp programmer 
at all...

What exactly are the features you're thinking about?

For example, I read this at the MMD site, but virtually all of these
are already implemented in Org-mode:
--------------------------------------------
MultiMarkdown adds these features to the basic Markdown syntax:

    footnotes
    tables
    citations and bibliography (works best in LaTeX using BibTeX)
    math support
    automatic cross-referencing ability
    smart typography, with support for multiple languages
    image attributes
    table and image captions
    definition lists
    glossary entries (LaTeX only)
    document metadata (e.g. title, author, etc.)
------------------------------------------

Regards,

Herb

I'd especially would love to be able to use Markdown to write
equations which -to me- is much more comfortable than writing latex
equations. Second I'd love to be able to export to MMD when I run into
problems with the latex exporter (I had plenty!). Third in my eyes it
would be nice to have as few markdown syntaxes as possible (I know
that is kind of a dream ;-)).

Best Markus

Hi,

May I suggest a feature that when the point is inside a TeX source block and
"C-c C-c" is pressed, instead of showing the error "No org-babel-execute
function for tex!", can we process the current tex block to output the dvi or
pdf file?

Thanks,

York

I'd rather define a org-babel-execute:tex function for that. 

Maybe look at org-babel-execute:* functions and suggest one?

Thanks!

Hi Bastien,

I think this is a good idea. By `org-babel-execute:tex' do you mean
`org-babel-execute-tex'?

No, I mean org-babel-execute:tex.

There is a whole family of Babel functions that let C-c C-c act 
upon a source block, with respect to the langage used.

Do `C-h f org-babel-execute: TAB' to see the list of available
function for your configuration.

Then you can pick up a langage you are familiar with in this 
list, jump to the Emacs lisp function and start getting familiar
with the code to write your own org-babel-execute:tex function.

But wait, there is already org-babel-execute:latex, so I think 
part of the problem is already solved.

Good exploration,

The output of C-u C-x =
should show some key sequences that would insert this character.

It already does, if the currently enabled input method can input it.

The functionality isn't really complete though, and could be improved.
For instance, it only works for some input methods -- e.g. "tex", but
not "korean-hangul".  Also it would nice if it would show other input
methods when the current input method doesn't handle a character.

Type "C-x 8 RET" followed by the hexadecimal code of the character
(shown by "C-u C-x ="), and Bob's your uncle.

Would mentioning that in the text do the job?

Or when using the ucs input method: uNNNN (that works only for BMP
characters).

Yes, it would.  That is an obscure command,
and I would not know what search string to use
to find it with apropos.

I think there is a way to enter characters by their long names, too,
but I don't recall what it is.  It would be good to mention that
method too.

`C-x 8 RET' (command `ucs-insert') also lets you complete against the char name.

FWIW - 

1. I use a variant (`ucsc-insert') of `ucs-insert' that has the same behavior
except for a negative prefix arg (`ucs-insert' is anyway a no-op for such an
arg):

* A negative arg is treated as its absolute value, so -3 inserts 3 copies of the
char, just like 3 does.

* A negative arg also automatically creates a command that inserts the same
character (accepting a prefix arg for multiple copies).  The command name is the
same as the char name, except lowercase and with SPC chars replaced by hyphens
(`-').  I bind it to `C-x 8 RET', obviously.

For example, if you use `C-- C-x 8 RET greek capital letter delta' (e.g., using
completion), then it defines a command `greek-capital-letter-delta' that inserts
that char.  Convenient for binding keys to effectively add Unicode chars to your
keyboard.

2. I define a macro, `ucsc-make-commands', that takes a regexp arg and defines
all such insertion commands for chars whose names match the regexp.

Examples:

(ucsc-make-commands "^math") ; Math symbols
(ucsc-make-commands "latin") ; Latin alphabet characters
(ucsc-make-commands "arabic")
(ucsc-make-commands "^cjk")  ; Chinese, Japanese, Korean characters
(ucsc-make-commands "^box drawings ")
(ucsc-make-commands "^greek [a-z]+ letter") ; Greek characters
(ucsc-make-commands
  "\\(^hangul\\|^circled hangul\\|^parenthesized hangul\\)")

Note that a drawback to using `ucs[c]-insert' with completion is that it is slow
- there are *many* Unicode chars.  This lets you use it when you really need it,
but have tailor-made insertion commands for the chars you use often.  And of
course even if you do not bind most such commands, completion against their
names is much quicker, since the domain is smaller (even if you create a lot of
such commands).

The code is here:
http://www.emacswiki.org/emacs/download/ucs-cmds.el
I have no objection to it being added to Emacs (the patch is trivial).

Re: Feature suggestion

    `C-x 8 RET' (command `ucs-insert') also lets you complete against the char name.

The C-u C-x = message could mention both ways of using it -- why not?

It does already mention the character name, which can entered directly
at the C-x 8 RET prompt.

an alias `char-insert' might help a lot WRT apropos

Yes.  My point is this text should SAY you can enter the name that way.

I've done both in revision 108521 on the trunk.  It now says

      to input: type "C-x 8 RET HEX-CODEPOINT" or "C-x 8 RET NAME"
