Update ispell-dictionary to text language

Update ispell-dictionary to text language

[Sébastien Vauban]

Hello,

Here my proposal (and my very first self-written chunk of ELisp code) for
switching to the right language for ispell, upon reading the contents of the
meta-tag `LANGUAGE'.

--8<---------------cut here---------------start------------->8---
  (defun org-switch-language ()
    "Switch language for Org file, if a `#+LANGUAGE:' meta-tag is on top 14 lines."
    (save-excursion
      (goto-line 15)
      (if (re-search-backward "#\\+LANGUAGE: +\\([A-Za-z_]*\\)" 1 t)
          (ispell-change-dictionary (match-string 1)))))
--8<---------------cut here---------------end--------------->8---

That should be hooked, such in:

--8<---------------cut here---------------start------------->8---
  (add-hook 'org-mode-hook
            (lambda ()
              ;; file modification date
              (set (make-local-variable 'time-stamp-format) "%:y-%02m-%02d")
              (set (make-local-variable 'time-stamp-start) "^#\\+DATE: +")
              (set (make-local-variable 'time-stamp-end) "$")

              ;; guess language
              (org-switch-language)

              ;; flyspell mode to spell check everywhere
              (flyspell-mode 1)))
--8<---------------cut here---------------end--------------->8---

Maybe that could become a default in Org. I think that makes sense.

Comments are (more than) welcome...

Best regards,
  Seb

I think using File Variables are better for this. For no particular
reason except they are standardized and don't require any additional
code in Org Mode.
(info "(emacs)Specifying File Variables")
# -*- ispell-local-dictionary: "german" -*-

I know them, even use them in directories (see `.dir-locals.el'), instead of
files.

--8<---------------cut here---------------start------------->8---
((org-mode . ((ispell-local-dictionary . "american")
              (time-stamp-format . "%:y-%02m-%02d")
              (time-stamp-start . "^#\\+DATE: +")
              (time-stamp-end . "$"))))
--8<---------------cut here---------------end--------------->8---

BUT there is a *language specification* in the Org template:

--8<---------------cut here---------------start------------->8---
#+TITLE:     Scorpios.org
#+AUTHOR:    Seb Vauban
#+EMAIL:     no-LMehjL4SQ+Y@public.gmane.org
#+DATE:      2010-01-13 Wed
#+DESCRIPTION: 
#+KEYWORDS: 
#+LANGUAGE:  en
--8<---------------cut here---------------end--------------->8---
             ^^

AND it is *used by Org* (at least for the HTML export, and for LaTeX as well I
think -- or, in any case, it should use it).

Thus, I try to avoid declaring which language is used in the buffer at two
different spots, because we can change one and forget to change the other.

Therefore, I would like to keep only one language declaration (the one of the
Org template, in this case), and get Emacs follow it.

Does this make sense?

Best regards,
  Seb

I have seen this thread and I am still contemplating what
to do with it.  More input and opinions would be welcome.

My arguments are:

- We have a language specification in the Org template
- That should be used during the export to HTML (DONE)
- That should be used during the export to LaTeX (TODO)
- That should be used for editing the buffer in the right language (TODO/DONE,
  see my proposal)

I'm quite against /mixing language declarations/:
- in the Org template *and*
- in buffer local variables.

Of course, we could imagine the other way around: using the value of
`ispell-local-dictionary' for the 3 objectives (edition in correct language,
correct setting for generated HTML, correct setting for generated LaTeX). It'd
be as good for me.

So do I!  ;-)

Hi Seb,
Hi Carsten,

I guess it depends highly on the definition. I can see Sebastien's points. It 
is somewhat strange to have a header-row "language" which does not have 
anything to do with the way how org-mode (resp. emacs) handels the org-buffer.
And the danger to use two different places + the confusion of two slightly 
different styles may confuse esp. newbies like me.

However, on the other side, it is said that C-c C-e t "insert the *export* 
option template". Which strongly refer to export features.

I guess it would be more clear if there is a #+EXPORT_LANGUAGE tag.
But to change this now is stupid as well. 

So not right sure what to do. 
Maybe leave it to people and offer a flag to say in the org config something like 
export_language is equal to ispell_language (maybe working both directions) 

Just two newbie-cents

Hi everyone,

in the end I decided to not do this change.  I am uncomfortable to  
link these different areas in Emacs in a way that is fixed.

Maybe you want to post your code in org-hacks.php on Worg.... ?
