$buffer-ipipe(5)

NAME

$buffer-ipipe - Divert buffer incremental pipe input through macro.

SYNOPSIS

$buffer-ipipe commandName

DESCRIPTION

$buffer-ipipe allows the buffer incremental pipe input mechanism to be diverted through a command macro defined by commandName. On a buffer running an ipipe-shell-command(2) the command, set by this variable, will be called whenever new text has been inserted by the executing process. Two alpha-marks will be set in the buffer, 'i' denotes the start of the newly inserted text and 'I' denotes the end.

When the ipiped command exits the commandName is called with a numeric argument of 0 and the $result(5) variable is set to the exit code of the process, this will be the last call of the command. The following values of $result are also used by MicroEmacs:

-1000


The ipiped process did not exit normally, cause unknown.

-1009


The ipiped process was killed.

-1011


The ipiped process core dumped.

-1015


The ipiped process was terminated.

Not all platforms support all of these exit codes.
