smart-newline.el
================
[](https://travis-ci.org/ainame/smart-newline.el)
The `smart-newline.el` provide a stress-less newline command for programmer.
This extension's usage is VERY SIMPLE. Because, you have to ONLY press `RET` key.
## INSTALL
write in your ~/.emacs.d/init.el
```lisp
(setq el-get-sources '(
(:name smart-newline
:type github
:website "https://github.com/ainame/smart-newline.el"
:pkgname "ainame/smart-newline.el")
)
)
```
after `M-x el-get-list-packages`
## CONFIGURATION
write in your ~/.emacs.d/init.el
* by minor-mode
`smart-newline` command bind to `RET` and `C-m`.
```lisp
(smart-newline-mode 1)
```
or
```lisp
(add-hook 'ruby-mode-hook ;; or any major-mode-hooks
(lambda ()
(smart-newline-mode 1)))
```
* by only using any key-bind
```lisp
(define-key global-map (kbd "C-j") 'smart-newline) ;; or any key as you like
```
## BEHAVIORS
List up smart-newline behaviors.
In this section, I use following words.
* newline - Emacs's default command at `RET` or `C-m`
* open-line - Emacs's default command at `C-o`
* indent - `indent-according-to-mode` command and almost Emacs's default command at `TAB` or `C-i`
And in these sample figures, `|` representation editor's cursor.
In this description, display in ruby-mode patterns for example.You can see some patterns in other major-mode in [test cases](https://github.com/ainame/smart-newline.el/tree/master/test) .
### pattern 1
```ruby
def foo| RET def foo
end -> |
end
```
`newline and indent` when the cursor exists at end of line.
* default Emacs: `C-j` / `RET` -> `TAB`
* smart-newline: `RET`
### pattern 2
```ruby
def foo RET def foo
|end -> |
end
```
`open-line and indent` at begininng of line which has chars.
* default Emacs: `C-o` -> `TAB`
* smart-newline: `RET`
### pattern 3
```ruby
object = |VeryVeryVeryLongSomeClassName.create_object
| RET
V
object =
|VeryVeryVeryLongSomeClassName.create_object
```
`newline and indent` like `C-j`
* default Emacs: `C-j` / `RET` -> `TAB`
* smart-newline: `RET`
### pattern 4
```ruby
def foo def foo def foo
end RET end RET end
| ---> | --->
def bar |
end def bar
end def bar
end
```
You can insert balanced blank line around start point by only `RET`.
At the end, you will write new a method in smooth.
* default Emacs: `RET` -> `RET` -> `C-p` / `RET` -> `C-o`
* smart-newline: `RET` -> `RET`
### pattern 5
```ruby
def foo def foo
end end
RET
| ---> |
def bar
end def bar
end
```
* default Emacs: `C-o`
* smart-newline: `RET`
### pattern 6
```ruby
def foo def foo def foo def foo
end RET end RET end RET end
|def bar ---> | ---> | --->
end def bar |
end def bar
end def bar
end
```
* default Emacs: `C-o` -> `C-o` -> `RET`
* smart-newline: `RET` -> `RET` -> `RET`
### pattern 7
```ruby
def foo def foo def foo def foo
end| RET end RET end RET end
def bar ---> | ---> --->
end def bar | |
end def bar
end def bar
end
```
* default Emacs: `RET` -> `RET` -> `C-o`
* smart-newline: `RET` -> `RET` -> `RET`
