# Shortcut for Syntax Highlighting in Keynote

The idea is based on a [gist by @jimbojsb](https://gist.github.com/jimbojsb/1630790).

You can use [Pygments](http://pygments.org) or [Highlight](http://www.andre-simon.de/doku/highlight/en/highlight.php).

## Install Pygments

`brew install python`

`pip install pygments --pre` (pre is currently required to get version 2.0rc1, which adds `fontsize` to the rtf formatter)

Pygments quick help:
  - show available styles, formatters, etc: `pygmentize -L`
  - show help for a formatter: `pygmentize -H formatter rtf`
  
Styles
  - `pygmentize -L style`
  - previews: http://help.farbox.com/pygments.html
  - others are available: `pip search pygments`, e.g. `pip install pygments-style-solarized` or `pip install pygments-style-github`
  
## Install Highlight

`brew install highlight`

Styles: `highlight --list-themes`

## Create a Service

Start the Automator, `File` - `New`, choose `Service`.

Add `Copy to Clipboard`, then `Run AppleScript`.

Paste the script below, adjust to your preferences:

```
-- for pygmentize
set command to "/usr/local/bin/pygmentize -l scala -f rtf -O style=github,fontface=\"Source Code Pro\",fontsize=48"

-- for highlight
-- set command to "/usr/local/bin/highlight --syntax scala --out-format rtf --style solarized-light --font \"DejaVu Sans Mono\" --font-size 24"

do shell script "/bin/bash -c 'pbpaste | " & command & " | pbcopy'"

tell application "System Events" to tell (process 1 where frontmost is true)
  click menu item "Paste" of menu 1 of menu bar item "Edit" of menu bar 1
end tell
```

Save the service as `Syntax Highligh` (or a different name).

Go to `System Preferences` - `Keyboard` - `Shortcuts`. Under `Services`, look for your new service and add a shortcut.

Go to `System Preferences` - `Security & Privacy` - `Privacy`. Under click the lock on the bottom left. Under `Accessibility`, add Keynote (or PowerPoint) to the list of apps.

In Keynote, create a text box and add some code. Select the code and hit your shortcut. That should replace the text by its highlighted version.
