+ "Execute string COMMAND in inferior shell with region as input.
|
|
|
+
|
|
|
+A copy of the emacs 23.1.1 function.
|
|
|
+
|
|
|
+Normally display output (if any) in temp buffer `*Shell Command Output*';
|
|
|
+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."
