Mathematica Autocompletion Tweaker
================================

Changes the behavior of the autocompletion in Mathematica version 9.0.0 (**and unfortunately, it will only work in this very version!**) so that CamelCase completion can be used.
CamelCase allows not only for the expansion of prefixes like `Integ` for `IntegerDigits`, it allows additionally to specify
the capital letters (the humps) in function names only and therefore, e.g.  `ListLiPlo`, `ListLPlot` or even `LLP` can be 
expanded to `ListLinePlot`.

To be really fast with this kind of help you have to try avoiding arrow-keys for going down the suggestion list. 
Instead, you should specify your wanted function further and further by leaving out the small letters between capital 
CamelCase letters. A very good example is `Hypergeometric0F1`. Instead of typing `Hy` and going down the list very far, 
you leave out 12 letters and type `Hy0`. In many, many cases this leads to only one unique choice of an expansion and 
you only have to press <kbd>Enter</kbd> (or <kbd>Tab</kbd>) to accept it.

If there are still several choices in the end, *then* you can use your arrow keys. One example here is, when you 
typed (heroically) `LLLP` to shorten `ListLogLinearPlot` and see that there is a `ListLogLogPlot` with the same 
abbreviation. Unfortunately, at this point even typing `LLLPlot` does not help to make it clear and you have to use 
the arrow key to choose the right function.

**Completion of usual function names** works now both ways:

1. You get valid expansions if you type a *prefix* of the function like `Integ` for `IntegerDigits`.
2. Additionally, you can type `IntDig`, `InDi` or just `ID` to get `IntegerDigits` too. Important is that you take care 
of the capital letters in the names.

Support for **completion of `Options`** was added too.

Additionally, camel-humps even work **after context specifications**. Note, that the context-names themselves cannot 
be camel-humps expanded because in most cases like `Developer`, `Experimental`, `Internal`, etc. this would be useless anyway.

Additionally, when I had a first version of this running, I created a teaser screen-cast:

Installation
------------

A simple `Get` of the `MathematicaAutocompletionTweaker.m` package turns the camel-humps completion on:

```
Get["http://goo.gl/wtVze"]
```

In Mathematica 9 you should now see a suggestion box when you type e.g. `PP`. If you want to turn it off again can 
restart the kernel or you use ``FE`RecoverDefaultCompletion[]``.

If you want to install it permanently you can for instance copy the contents of `MathematicaAutocompletionTweaker.m` into
your `init.m`. Given the case, that the autocompletion is really used by some users, I'll prepare an easier method
to install small, system-specific code for permanently use.
