usage of bgein_src in 'Literal examples' section

[Patrick Drechsler]

Hi,

I like the new feature in "literal examples" using #+BEGIN_SRC <mode>!

But how do I find which mode Emacs is using for a certain file type?

I could not figure out how to replace <mode> for simple C or CPP files.

Here is a simple C file:

--8<---------------cut here---------------start------------->8---
int main(void)
{
	return 0;
}
--8<---------------cut here---------------end--------------->8---

I have tried different results from `M-x describe-mode' as well as stuff
like:

#+BEGIN_SRC c
#+BEGIN_SRC c/law
#+BEGIN_SRC cc
#+BEGIN_SRC c-mode
#+BEGIN_SRC cc-mode

What is the correct <mode> to insert?

The doc-string says this:

,----
|    If the example is source code from a programming language, or any
| other text that can be marked up by font-lock in Emacs, you can ask
| for the example to look like the fontified Emacs buffer(1).  This is
| done with the `src' block, where you also need to specify the name of
| the major mode that should be used to fontify the example:
| 
|      #+BEGIN_SRC emacs-lisp
|      (defun org-xor (a b)
|         "Exclusive or."
|         (if a (not b) b))
|      #+END_SRC
`----

Maybe it would be nice to add something along the lines of:

--8<---------------cut here---------------start------------->8--- 

You can find out the Emacs mode corresponding to your source language by
visiting a file in the particular mode and calling 

`M-x <describe?-???>'.

--8<---------------cut here---------------end--------------->8---

TIA

Patrick

This works for me:

* C Source Example
#+BEGIN_SRC c
int main(void)
{
  return 0;
}
#+END_SRC

And then C-c ' anywhere inside the block

Yes, it did, thanks a lot Bernt!

Mmmh, I just have to many emacs devel versions currently on my system to 
reproduce the original error at the moment...

But how do I find out which is the correct string for the Emacs mode?

Is there a `M-x describe-??' method?

I think any function ending in '-mode' would be valid

If you open a file and it automatically loads the correct mode the mode
is listed on the modeline in ()
e.g. while composing this message it's (Message MML Fly OrgStruct) as
major mode and minor modes.

There's a variable 'auto-mode-alist' (C-h v auto-mode-alist) which lists
the mappings of filenames to modes.

I have entries like this in mine:

 ("\\.txt$" . outline-mode)
 ("\\.css\\'" . css-mode)
 ("\\.py\\'" . python-mode)
etc

so for *.py files which use python-mode

#+BEGIN_SRC python
def foo():
    print "in foo"
    10

if __name__ == '__main__':
    foo()
#+END_SRC

HTH,
Bernt

PS. Sorry I didn't answer that the first time around...

Thank Bernt, this the the variable I was looking for!

You can also load the file into Emacs and then check the value of
the variable `major-mode' in that buffer.  It will be c-mode or org-mode
or whatever.  From this value, just strig the "-mode" and you have
the value you need to use in the begin_src line.

This also works fine, thanks for your feedback Dominik. As mentioned in
a previous mail I got a bit confused between different emacs buidls on
my machine, sorry for the noise.
