the current source-code block. For example the following

reference would be replaced with the body of the source-code
|

|
|

|
|
|
Note that any text preceding the <<foo>> construct on a line will
|
|
|
|
be interposed between the lines of the replacement text. So for
|
|
|
|
example if <<foo>> is placed behind a comment, then the entire

replacement text will also be commented.

This function must be called from inside of the buffer containing

|
|
|
the source-code block which holds BODY.
|
|
|
|
|
|
|
|
In addition the following syntax can be used to insert the
|
|
|
|
results of evaluating the source-code block named 'example-block'.

|

2009-12-17 18:22:00 +00:00

Any optional arguments can be passed to example-block by placing
|
|
|
|
the arguments inside the parenthesis following the convention
|
|
|
|
defined by `org-babel-lob'. For example
|
|
|
|
|
2009-12-17 18:22:00 +00:00
|
|
|
<<example-block(a=9)>>
|
2009-10-28 22:13:33 +00:00
|
|
|
|
|
|
|
would set the value of argument \"a\" equal to \"9\". Note that
|
2009-12-17 18:22:00 +00:00
|
|
|
these arguments are not evaluated in the current source-code

|
Prefix arg means replace the region with it. Return the exit code of
|
|
|
|
COMMAND.
|
|
|
|
|
|
|
|
To specify a coding system for converting non-ASCII characters
|
|
|
|
in the input and output to the shell command, use \\[universal-coding-system-argument]
|
|
|
|
before this command. By default, the input (from the current buffer)
|
|
|
|
is encoded in the same coding system that will be used to save the file,
|
|
|
|
`buffer-file-coding-system'. If the output is going to replace the region,
|
|
|
|
then it is decoded from that same coding system.
|
|
|
|
|
|
|
|
The noninteractive arguments are START, END, COMMAND,
|
|
|
|
OUTPUT-BUFFER, REPLACE, ERROR-BUFFER, and DISPLAY-ERROR-BUFFER.
|
|
|
|
Noninteractive callers can specify coding systems by binding
|
|
|
|
`coding-system-for-read' and `coding-system-for-write'.
|
|
|
|
|
|
|
|
If the command generates output, the output may be displayed
|
|
|
|
in the echo area or in a buffer.
|
|
|
|
If the output is short enough to display in the echo area
|
|
|
|
\(determined by the variable `max-mini-window-height' if
|
|
|
|
`resize-mini-windows' is non-nil), it is shown there. Otherwise
|
|
|
|
it is displayed in the buffer `*Shell Command Output*'. The output
|
|
|
|
is available in that buffer in both cases.
|
|
|
|
|
|
|
|
If there is output and an error, a message about the error
|
|
|
|
appears at the end of the output.
|
|
|
|
|
|
|
|
If there is no output, or if output is inserted in the current buffer,
|
|
|
|
then `*Shell Command Output*' is deleted.
|
|
|
|
|
|
|
|
If the optional fourth argument OUTPUT-BUFFER is non-nil,
|
|
|
|
that says to put the output in some other buffer.
|
|
|
|
If OUTPUT-BUFFER is a buffer or buffer name, put the output there.
|
|
|
|
If OUTPUT-BUFFER is not a buffer and not nil,
|
|
|
|
insert output in the current buffer.
|
|
|
|
In either case, the output is inserted after point (leaving mark after it).
|
|
|
|
|
|
|
|
If REPLACE, the optional fifth argument, is non-nil, that means insert
|
|
|
|
the output in place of text from START to END, putting point and mark
|
|
|
|
around it.
|
|
|
|
|
|
|
|
If optional sixth argument ERROR-BUFFER is non-nil, it is a buffer
|
|
|
|
or buffer name to which to direct the command's standard error output.
|
|
|
|
If it is nil, error output is mingled with regular output.
|
|
|
|
If DISPLAY-ERROR-BUFFER is non-nil, display the error buffer if there
|
|
|
|
were any errors. (This is always t, interactively.)
|
|
|
|
In an interactive call, the variable `shell-command-default-error-buffer'
|
|
|
|
specifies the value of ERROR-BUFFER."
