3. To integrate shell with Emacs.

You can integrate shell with Emacs with `e-pipe'.

3.1 e-Pipe		e-pipe and pipe-buffer
3.2.1 syntax of 'e-pipe'		syntax

3.1 e-Pipe

Almost UNIX shell can connect the command's stdout with the another command's stdin with `|' syntax.

On the other hand, Oneliner can connect the command's stdout with the Emacs-buffer, and it can connect the Emacs-buffer with the command's stdin, with `|' syntax. We call the syntax by the name of 'e-pipe'. The image diagram is as follows:

(Emacs Buffer) -> | commands | -> (Emacs Buffer)

3.2 PipeBuffer

You will use 'pipe-buffer' frequently on Oneliner.

'pipe-buffer' can be connected command with `|'(e-pipe).

'pipe-buffer' is appeared with simple operation as follows:

commands |

'pipe-buffer' has the number. When you append the number, you can select one 'pipe-buffer' from some 'pipe-buffer's.

We defined terms as follows:

• We call the buffer `*Oneliner pipe*N' by the name of 'pipe-buffer'. ( N is 0 ... )

• We call the buffer `*Oneliner pipe*0' by the name of 'default-pipe-buffer'.

3.2.1 syntax of 'e-pipe'

3.3 This is an explanation of 'e-pipe' syntax. You can omit the syntax in '[]'.

[buf-spec]| commands [+]|[buf-spec][!]

This is explanations syntax in '[]'.

`buf-spec'

`When omited.'

It means the default pipe-buffer.

`When specified a number.'

It means the numbered pipe-buffer.

`When specified `@buffer-name''

It means a Emacs-buffer( This is not a pipe-buffer ). Do not insert space character at around the buffer name.

`+'

It means addition to pipe-buffer.

`!'

It means a request of evaluation of output pipe-buffer. The action starts after output process was done.

Some examples with 'e-pipe' syntax is as follows:

find ./ -name \*.c | | wc | sort | 1| awk '{print $1}' | grep 10 | sort -n |9 cat file +| cat file +|@*scratch* @sample.c| wc echo "(emacs-version)" |! echo "(find-file \"a.c\")" |!
