Patch by Carsten
* lisp/org-exp.el (org-export-mark-blockquote-verse-center): fixed
small bug, now grabbing match data before overwritten by looking-at
this fixes a problem with remainders of #+end_quote lines appearing
in exported output
* lisp/org-latex.el (org-export-latex-fixed-width): now checking
org-example rather than org-protected on verbatim export, because by
default all ": " prefixed lines are marked protected
thanks to Christopher Allan Webber for catching this
* lisp/babel/langs/ob-python.el (org-babel-python-table-or-string):
now more careful not to replace "None"s which are not isolated
portions of lists
Thanks to Christopher Witte for raising these issues
* lisp/babel/langs/ob-haskell.el (org-babel-expand-body:haskell):
replaced missing () wrapping, and now using correct variable
expansion
(org-babel-execute:haskell): now using
org-babel-haskell-initiate-session to start sessions
(org-babel-haskell-initiate-session): only starting sessions if none
exists, also added a .25 second wait on brand new sessions to allow
the Haskell interpreter to fire up
(org-babel-load-session:haskell): now optionally accepts processed
params to avoid over-execution of variable resolution
(org-babel-prep-session:haskell): now optionally accepts processed
params to avoid over-execution of variable resolution, also placing
the variable definitions directly in the session instead of loading
them from a separate file
* lisp/org-entities.el (org-entities): Restructure the list.
(org-entities-help): Turn the help output into a buffer
in Org-mode, so that it becomes easier to find a symbol
in the structure.
(org-entities-create-table): Deal with new structure.
Thanks to Daniel Mahler for finding this problem and proposing the fix
* lisp/babel/ob.el (unless): ensure `declare-function' is available in
all Emacsen
A quick example of accessing remote json data from Babel code blocks.
Evaluate the following to see a listing of parks in DC by ward.
#+source: dc-parks
#+begin_src emacs-lisp :var keys='(ward address) :var data=json(url="http://ogdi.cloudapp.net/v1/dc/RecreationParks?format=json")
(append
(list keys 'hline)
(mapcar
(lambda (lis) (mapcar (lambda (key) (cdr (assoc key lis))) keys))
(cdr (car data))))
#+end_src
* lisp/org-macs.el (org-not-nil): Return the value if not interpreted
as nil.
* lisp/org.el (org-entry-get):
(org-entry-get-with-inheritance): Interpret the value "nil"
as nil for properties.
