# Babel REPL for emacs
[](http://melpa.org/#/babel-repl)
## Acknowledgement
Thanks tmtxt for his plugin [n4js.el](https://github.com/tmtxt/n4js.el)
## Dependencies
- `babel-cli`: `npm install -g babel-cli`
## Installation
### Melpa
[babel-repl](http://melpa.org/#/babel-repl)
### Manual install

```lisp
(add-to-list 'load-path "~/.emacs.d/babel-repl/")
```
### Load the library
- Load the library with `require`
```lisp
(require 'babel-repl)
```
### Weird characters workaround
If you get weird characters in your REPL. Add this code snippet to your configuration file.
```lisp
(require 'comint)
(add-to-list 'comint-preoutput-filter-functions
(lambda (output)
(let ((case-fold-search nil))
(replace-regexp-in-string "\033\\[[0-9]+[A-Z]" "" output))))
```
## Variables
Change these variables based on your demand
- `babel-repl-cli-program`: the name of babel node cli program, default to
`babel-node`. Change it to absolute path if it's not in your load path.
```lisp
(setq babel-repl-cli-program "/path/to/babel-node")
```
- `babel-repl-cli-arguments`: the list of arguments to pass to `babel-node`.
- `babel-repl-pop-to-buffer`: whether to pop up the babel shell buffer after sending
command to execute.
- `babel-repl-pop-to-buffer-function`: the function used for pop up the babel node
buffer if the above variable is set to t. Default is `pop-to-buffer`. An example
is `pop-to-buffer` to pop up the babel buffer to current window
instead of other window.
## Commands
- `babel-repl`: start a babel node process
- `babel-repl-send-current-region`: send the active region to babel node process
- `babel-repl-send-buffer`: send the whole buffer to babel node process
- `babel-repl-send-paragraph`: send the paragraph at point to babel node process
- `babel-repl-send-region-or-buffer`: send the current region if active, otherwise send
the whole buffer to babel node process
- `babel-repl-send-dwim`: send the current region if active, otherwise send the
paragraph at point to babel node process
- `babel-repl-switch-to-buffer`: switch to babel node buffer if exist, otherwise,
