select a section of text and run it into another process?

select a section of text and run it into another process?

[Sayth Renshaw]

My emacs is going well, but something I would like to be able to do is run a section of code in a file and send it to an eshell process of python/ipython to evaluated.

How do I do this, I am not sure how to select the text without using the mouse, there are a lot of people guessing on this SO question (http://stackoverflow.com/questions/657672/how-to-select-or-highlight-a-block-in-emacs) but can anyone provide a solid answer? 

In the emacs manual it shows this article for sending to process http://www.gnu.org/software/emacs/manual/html_node/elisp/Input-to-Processes.html

which means I assume I could make a keybinding adaption if this

(process-send-string "shell<1>" "ls\n")

(process-send-string "eshell<ipython>" "some version of selected text")

Any ideas or is there a plugin that already does this? I would like to be able to do this with multiple file types but python is where I am starting.

Thanks

Sayth

To send a portion of text to a process (not eshell, but a program that
Emacs will invoke), select the text and then type "M-|".  Emacs will
prompt for the command to invoke on this text.

Type "C-SPC" on one edge of the text, then move to the other.  That's
all; the text between those two points is now selected.

That question is confusing because the question wasn't very clear that 
it was talking about rectangular regions, not ordinary regions. Some of 
the answers recognized this, some didn't.

The built-in Emacs tutorial explains how to mark a region, although it 
doesn't really go into detail or use that term, it just describes the 
process as part of the method of killing the region:

You can also kill any part of the text with one uniform method.  Move
to one end of that part, and type C-@ or C-<SPC> (either one).  (<SPC>
is the Space bar.)  Move to the other end of that part, and type C-w.
That kills all the text between the two positions.

So

C-spc then M-! And then command Eg python.

Would it make sense to base M-! on filetype so that it would automatically run to correct process?

We already have something like that in dired-x.el, which see.

Like in cider which can be seen in this article http://www.braveclojure.com/using-emacs-with-clojure/

C-X c-e sends the line in the editor to a repl instance.

Actually  think I found a solution there a some modes python.el already has an implementation.

There is isend-mode http://showterm.io/2b2a4b6759004598de4ee#slow which can be configured for any language. https://github.com/ffevotte/isend-mode.el

Somebody ought to mention Org, which can take arbitrary chunks of
text/code and run them through external interpreters and "do things"
with the results. See the "Working with source code" section of the Org
manual.
