### Install vim
You will probably need to install vim
```bash
sudo apt-get install vim
```
Is an excellent choice for linux and mac users, it is lighweight (runs from the console) commands available from vim:-
```bash
:!jruby % # will run the sketch
```
### Live coding with Pry ###
```bash
jgem install pry
# or jruby -S gem install pry
# or if you must use rvm or rbenv not recommended
```
Do `echo "Pry.config.editor = 'vim'" > ~/.pryrc` to set vim as the pry editor.
Fire up pry using
```bash
jruby -e "require 'pry'; binding.pry"
```
Or more conveniently create a shortcut by using `jpry` alias in your `.bashrc` or equivalent eg `.profile` debian linux:-
```bash
alias jpry="jruby -e \"require 'pry'; binding.pry\""
```
At the pry prompt:-
```ruby
load 'my_sketch'
```
Creating `my_sketch` is a easy as `picrate -c my_sketch 300 300`
To get full listing of sketch in pry enter `$` at the prompt, to edit the `draw` method at the prompt do:-
```bash
edit -p MySketch#draw
```
On finished save and quit `:wq` (or `:wqa` to save all changed buffers) sketch will redraw reflecting changes, but you can repeat:-
```bash
edit -p MySketch#draw
```
this allows you to edit your changes which are saved in a `.tmp` file. Read more about vim / emacs integration [here][pry-wiki]
### Other advantages of vim ###
Also because vim is run from the console it is so easy to run old friends like `rubocop` or `reek` on your sketch code.
If you are millenial and allergic to the command line install use an editor that supports ruby syntax, emacs is only for hardcore geeks. As yet I don't think the raspberrypi supports `atom` as an editor.
