*** Fontify code in code blocks.
|
||||
|
||||
Source code in code block can now be fontified. Please customize
|
||||
the varable =org-src-fontify-natively=, but be prepared for some
|
||||
editing delays in large blocks. Thanks to Dan Davison for this.
|
||||
|
||||
*** Language-mode commands are available in the Org-buffer
|
||||
The most general machinery for doing this is the macro
|
||||
`org-babel-do-in-edit-buffer'. There is also the convenience
|
||||
function `org-babel-do-key-sequence-in-edit-buffer' which makes
|
||||
use of this macro, and is bound to C-c C-v C-x and C-c C-v x. If
|
||||
there is an active region contained within the code block, then
|
||||
this is inherited by the edit buffer. Some examples of the sorts
|
||||
of usage this permits are
|
||||
|
||||
C-c C-v C-x M-; comment region according to language
|
||||
C-c C-v C-x C-M-\ indent region according to language
|
||||
|
||||
Users can make these more convenient, e.g.
|
||||
|
||||
(defun my/org-comment-dwim (&optional arg)
|
||||
(interactive "P")
|
||||
(or (org-babel-do-key-sequence-in-edit-buffer "\M-;")
|
||||
(comment-dwim arg)))
|
||||
|
||||
(define-key org-mode-map "\M-;" 'my/org-comment-dwim)
|
||||
|
||||
A common instance of this general pattern is built in to Org-mode,
|
||||
controlled by the variable `org-src-tab-acts-natively': if this
|
||||
variable is set, then TAB in a code block has the effect that it would
|
||||
have in the language major mode buffer.
|
||||
|
||||
*** Org-babel commands are available in language-mode edit buffer
|
||||
Mirroring the language-native commands in Org buffers above, a new
|
||||
macro `org-src-do-at-code-block' and convenience function
|
||||
`org-src-do-key-sequence-at-code-block' provide the converse. When
|
||||
used in a language major-mode edit buffer (i.e. a buffer generated
|
||||
by C-c '), `org-src-do-key-sequence-at-code-block' executes a key
|
||||
sequence at the code block in the source Org buffer. The command
|
||||
bound to the key sequence in the Org-babel key map is executed
|
||||
remotely with point temporarily at the start of the code block in
|
||||
the Org buffer.
|
||||
|
||||
The command is not bound to a key by default, to avoid conflicts
|
||||
with language major mode bindings. To bind it to C-c @ in all
|
||||
language major modes, you could use
|
||||
|
||||
(add-hook 'org-src-mode-hook
|
||||
(lambda () (define-key org-src-mode-map "\C-c@"
|
||||
'org-src-do-key-sequence-at-code-block)))
|
||||
|
||||
In that case, for example, C-c @ t issued in code edit buffers
|
||||
would tangle the current Org code block, C-c @ e would execute
|
||||
the block and C-c @ h would display the other available
|
||||
Org-babel commands.

|
||||
*** New function `org-babel-switch-to-session-with-code'
|
||||
C-c C-v z (`org-babel-switch-to-session-with-code') is a variant of
|
||||
C-c C-v C-z (`org-babel-switch-to-session'): instead of switching to
|
||||
the session buffer, it splits the window between (a) the session
|
||||
buffer and (b) a language major-mode edit buffer for the code block in
|
||||
question. This can be convenient for using language major mode for
|
||||
interacting with the session buffer.
|
||||
|
||||
*** Improvements to R sessions
|
||||
R now uses standard ESS code evaluation machinery in the :results
|
||||
value case, which avoids unnecessary output to the comint
|
||||
buffer. In addition, the R command responsible for writing the
|
||||
result to file is hidden from the user. Finally, the R code edit
|
||||
buffer generated by C-c ' is automatically linked to the ESS
|
||||
session if the current code block is using :session.
|
||||
|
||||
*** Temporary file directory

All babel temporary files are now kept in a single sub-directory in

the /tmp directory and are cleaned up when Emacs exits.

commenting or indenting of the whole block.

*** LaTeX minted package for fontified source code export
|
||||
Patch by Dan Davison.
|
||||
|
||||
Patch by Dan Davison FIXME
|
||||
A non-nil value of `org-export-latex-minted' means to export source
|
||||
code using the minted package, which will fontify source code
|
||||
with color. If you want to use this, you need to make LaTeX use the
|
||||
minted package. Add minted to `org-export-latex-packages-alist', for
|
||||
example using customize, or with something like
|
||||
|
||||
(require 'org-latex)
|
||||
(add-to-list 'org-export-latex-packages-alist '("" "minted"))
|
||||
|
||||
In addition, it is neccessary to install
|
||||
pygments (http://pygments.org), and to configure
|
||||
`org-latex-to-pdf-process' so that the -shell-escape option is
|
||||
passed to pdflatex.
