Aloha all,

Code block caching doesn't seem to notice if the value of a variable  
argument has changed.  Here is what I get with Org-mode version  
7.01trans (release_7.4.93.g40264e.dirty) when I run both code blocks  
(I'm expecting caller to recognize that random has changed).

2011-01-01 Thread Thomas S. Dye

Aloha all,

I'm seeing some unexpected behavior with source blocks as I'm  
adding :cache yes as a multi-line header argument.  The top #+results:  
is with the addition of the #+header: :cache yes line.  Note the lack  
of a :results name and also the lack of the SHA1 hash.  The bottom # 
+results: line is the result before addition of the #+header: line.


#+srcname: r-edge-angle-histogram
#+header: :cache yes
#+begin_src R :results output :var x=whole-adzes :file r/ 
adze_edge_angle.png :width 400 :height 300

  library(ggplot2)
  adze.edge.angle - ggplot(x, aes(edge_angle))
  adze.edge.angle + geom_histogram(aes(y=..density..)) +
  geom_density(weight=2) + xlab(Measured cutting edge angle  
(degrees))

#+end_src

#+results:
[[file:r/adze_edge_angle.png]]

#+results: r-edge-angle-histogram
[[file:r/adze_edge_angle.png]]


All the best,
Tom

Aloha all,

Sorry for the noise.  I'm not sure how I was using version 7.01trans  
with release_7.4.93, but now that I'm using version 7.4 with that  
release, the code below works as expected.

[Orgmode] [Babel] [Ann] varied updates and improvements

2010-10-21 Thread Eric Schulte
Hello Babblers,

I've just merged in a large group of changes to Babel (authored by Dan
and myself) including a couple of user-visible enhancements and a
significant cleanup of the code base.  More information is available in
the Changes.org file (relevant sections included below).

Best -- Eric

Incompatible Changes 
=

Code block hashes 
--
Due to changes in the code resolving code block header arguments
hashing of code block results should now re-run a code block when
an argument to the code block has changed.  As a result of this
change *all* code blocks with cached results will be re-run after
upgrading to the latest version.

Testing update 
---
Anyone using the org-mode test suite will need to update the jump
repository for test navigation by executing the following from
the root of the org-mode repository.
git submodule update
Failure to update this repository will cause loading of
org-test.el to throw errors.

Details 


Multi-line header arguments to code blocks 
---
Code block header arguments can now span multiple lines using the
new =#+header:= or =#+headers:= lines preceding a code block or
nested in between the name and body of a named code block.
Examples are given below.

- multi-line header arguments on an un-named code block
  #+headers: :var data1=1
  #+begin_src emacs-lisp :var data2=2
(message data1:%S, data2:%S data1 data2)
  #+end_src
  
  #+results:
  : data1:1, data2:2

- multi-line header arguments on a named code block
#+source: named-block
#+header: :var data=2
#+begin_src emacs-lisp
  (message data:%S data)
#+end_src
  
#+results: named-block
: data:2

Unified handling of variable expansion for code blocks 
---
The code used to resolve variable references in code block header
arguments has now been consolidated.  This both simplifies the
code base (especially the language-specific files), and ensures
that the arguments to a code block will not be evaluated multiple
times.  This change should not be externally visible to the
Org-mode user.

Improved Caching 
-
Code block caches now notice if the value of a variable argument
to the code block has changed, if this is the case the cache is
invalidated and the code block is re-run.  The following example
can provide intuition for the new behavior.

  #+srcname: random
  #+begin_src R :cache yes
  runif(1)
  #+end_src
  
  #+results[a2a72cd647ad44515fab62e144796432793d68e1]: random
  0.4659510825295
  
  #+srcname: caller
  #+begin_src emacs-lisp :var x=random :cache yes
  x
  #+end_src
  
  #+results[bec9c8724e397d5df3b696502df3ed7892fc4f5f]: caller
  0.254227238707244
