And when merging header args, those from enclosing scopes take
precedence. For example, output to file from a source block is
implemented by (a) sending the output to file, and (b) having the
source block return the file name as its result. Before this change,
the file name returned could be set by a referenced source block (a
nested call), regardless of the value of the :file header arg of the
top-level source block.
Prior to this, reference resolution could fail with quoted
strings. E.g. this didn't work:
\#+srcname: py-id(a=1)
\#+begin_src python
a
\#+end_src
\#+lob: py-id(a="1")
This change allows org-file-properties to supply header args, and also
allows property inheritance if it has been enabled. Header-args
aquired from the item (or by inheritance) have precedence over those
aquired from org-file-properties.
If a [:file filename.ext] header arg is provided, then all graphical
output from the source block is captured on disk, and output of the
source block is a link to the resulting file, as with the
graphics-only languages such as gnuplot, ditaa, dot, asymptote. An
attempt is made to find a graphics device corresponding to the file
extension (currently .png, .jpg, .jpeg, .tiff, .bmp, .pdf, .ps,
.postscript are recognised); if that fails, png format output is
created.
Additionally, values for several arguments to the R graphics
device can be passed using header args:
:width :height :bg :units :pointsize
:antialias :quality :compression :res :type
:family :title :fonts :version :paper :encoding
:pagecentre :colormodel :useDingbats :horizontal
Arguments to the R graphics device that are not supported as header
args can be passed as a string in R argument syntax, using the header
arg :R-dev-args
An example block is (although both bg and fg can be passed directly as
header args)
\#+begin_src R :file z.pdf :width 8 :height 8 :R-dev-args bg="olivedrab", fg="hotpink"
plot(matrix(rnorm(100), ncol=2), type="l")
\#+end_src
(org-repeat-re): Improved regexp to include .+ and ++ leaders for repeat
strings.
(org-get-repeat): Now takes a string parameter `tagline', so the caller
can obtain the SCHEDULED repeat, or the DEADLINE repeat.
(org-clock-disable-clock-resolution): New customization variable that
disable automatic clock resolution on clock in.
(org-clock-in): If `org-clock-disable-clock-resolution' is set, do not
automatically resolve anything. This is does not affect idle-time
resolution, however, if `org-clock-idle-time' is set.
(org-agenda-auto-exclude-function): New customization variable for
allowing the user to create an "auto exclusion" filter for doing
context-aware auto tag filtering.
(org-agenda-filter-by-tag): Changes to support the use of
`org-agenda-auto-exclude-function'. See the new manual addition,.
See the new manual section on "Resolving idle time".
(org-clock-resolve-clock): If keeping or subtracting time results in a
clock out at a time in the past, and if the resolution occurred due to
idleness or invoking `M-x org-resolve-clocks', remember that past moment
in time. On the next clock in, the user will be prompted to see if they
want to back-date their new clock to then.
(org-clock-resolve): Do not jump the user to the location of a dangling
clock if the resolution is occuring due to an idle timeout. In that
case there is typically only one dangling clock, the active one, and
there is no value gained by shuffling their windows around to show it to
them. Being prompted to resolve an idle clock should be as inobtrusive
as possible.
(org-resolve-clocks-if-idle): New function that resolves only the
currently active clock if the user has exceeded the time returned by
`org-user-idle-seconds', based on the value of `org-clock-idle-time'.
(org-clock-in): If, after resolving clocks,
(org-clock-out): Cancel the `org-clock-idle-timer' on clock out.
This file should be with the other org files, and not in the staging
area. Also, when file names in mobileorg.org are interpreted, this
should be relative to org-directory. So we also require now that the
user set this variable.
(org-clock-resolve-clock): New function that resolves a clock to a
specific time, closing or resuming as need be, and possibly even
starting a new clock.
(org-clock-resolve): New function used by `org-resolve-clocks' that sets
up for the call to `org-clock-resolve-clock'. It determines the time to
resolve to based on a single-character selection from the user to either
keep time, subtract away time or cancel the clock.
(org-resolve-clocks): New user command which resolves dangling clocks --
that is, open but not active -- anywhere in the file list returned by
`org-files-list'.
(org-clock-in): Automatically resolve dangling clocks whenever a user
clocks in.
(org-clock-cancel): If the user cancels the solely clock in a LOGBOOK,
remove the empty drawer.
(org-clock-idle-time): New user customizable option for detecting
whether the user has left a clock idle. Note: it is only used in this
commit to test whether it's worthwhile to check OS X to get the Mac
user's current idle time. If the Emacs idle time is less than the
value, the user hasn't been away long enough to be worth checking (a
more expensive test than just getting Emacs idle time).
(org-user-idle-seconds, org-mac-idle-seconds)
(org-emacs-idle-seconds): This three functions, in conjunction
with the user customization variable `org-clock-idle-time', return
the number of seconds (as a floating point) that the user has been
away from their Emacs (or, if running on OS X, their computer).
(org-find-open-clocks): New function that returns a list of all open
clocks in the given FILE. Note that each clock it returns is a cons
cell of the format (MARKER . START-TIME). This "clock" value is used by
several of the new clock module utility functions.
(org-is-active-clock): New inline function which tests whether the given
clock value is the same as the currently active clock. Returns non-nil
if this is the case.
(org-with-clock-position): New macro that evaluates FORMS with point in
the buffer and at the position of the given clock. Changes to the
current clock are global.
(org-with-clock): New macro that evaluates FORMS with point in the
buffer and at the position of the given clock. However, changes to the
current clock are local and have no effect on the user's active clock.
This allows, for example, far any clock to be cancelled without
cancelling the active clock.
(org-clock-clock-in): New inline function that switches the active clock
to the given clock. If either the argument RESUME, or the global
`org-clock-in-resume', are non-nil, it will resume a clock that was
previously left open.
(org-clock-clock-out): New inline function that clocks out the given
clock value without affecting the currently active clock.
(org-clock-clock-cancel): New inline function that cancels the given
clock value without affecting the currently active clock.
(org-clock-out): Accept new third parameter `at-time', which permits a
clock to be clocked out at a specific time. Note that no attempt is
made to verify that the clock out time is later than the clock in time.
(org-files-list): New utility function for returning a list of all open
org-mode buffers, plus all files used to build the agenda buffer. Note
that not all the files will necessarily be visited by a buffer at time
of call.
(org-entry-beginning-position): Like the function
`line-beginning-position', this inline function returns the beginning
position of the current heading/entry.
(org-entry-end-position): Like the function `line-end-position', this
inline function returns the end position of the current heading/entry.
(org-clock-idle-time): New user customizable option for detecting
whether the user has left a clock idle. Note: it is only used in this
commit to test whether it's worthwhile to check OS X to get the Mac
user's current idle time. If the Emacs idle time is less than the
value, the user hasn't been away long enough to be worth checking (a
more expensive test than just getting Emacs idle time).
(org-user-idle-seconds, org-mac-idle-seconds)
(org-emacs-idle-seconds): This three functions, in conjunction
with the user customization variable `org-clock-idle-time', return
the number of seconds (as a floating point) that the user has been
away from their Emacs (or, if running on OS X, their computer).
(org-find-open-clocks): New function that returns a list of all open
clocks in the given FILE. Note that each clock it returns is a cons
cell of the format (MARKER . START-TIME). This "clock" value is used by
several of the new clock module utility functions.
(org-is-active-clock): New inline function which tests whether the given
clock value is the same as the currently active clock. Returns non-nil
if this is the case.
(org-with-clock-position): New macro that evaluates FORMS with point in
the buffer and at the position of the given clock. Changes to the
current clock are global.
(org-with-clock): New macro that evaluates FORMS with point in the

This allows, for example, far any clock to be cancelled without
cancelling the active clock.
(org-clock-clock-in): New inline function that switches the active clock
to the given clock. If either the argument RESUME, or the global
`org-clock-in-resume', are non-nil, it will resume a clock that was
previously left open.
(org-clock-clock-out): New inline function that clocks out the given
clock value without affecting the currently active clock.
(org-clock-clock-cancel): New inline function that cancels the given
clock value without affecting the currently active clock.
(org-clock-out): Accept new third parameter `at-time', which permits a
clock to be clocked out at a specific time. Note that no attempt is
made to verify that the clock out time is later than the clock in time.
(org-files-list): New utility function for returning a list of all open
org-mode buffers, plus all files used to build the agenda buffer. Note
that not all the files will necessarily be visited by a buffer at time
of call.
(org-entry-beginning-position): Like the function
`line-beginning-position', this inline function returns the beginning
position of the current heading/entry.
(org-entry-end-position): Like the function `line-end-position', this
inline function returns the end position of the current heading/entry.
This includes the required changes to org-babel.el and a
language-specific implementation for emacs-lisp. The emacs-lisp
changes are from a patch by Benny Andresen.
