For using Cppia to test with latest Haxe.

Get latest Haxe from: http://build.haxe.org/builds/haxe
setup haxelib ( I use lib in same level as haxe folder named haxeLibrary
```
haxelib setup
```

Install latest hxcpp

haxelib git hxcpp https://github.com/HaxeFoundation/hxcpp.git

Then go to your lib folder for haxe and into hxcpp folder, normally I just drag the folder to terminal ( on mac ).
run the commands from terminal to rebuild your hxcpp README.md#building-the-tools
run the commands to build cppia README.md#cppia
you can use cppia working-with-cppia/01.creating-cppia-script.html

Testing your library

You can put your tests above your methods, which solves the age old problem of do you clutter your library repo with the tests or put them is a separate repo - simple just put them with your code and just add one extra small class. haxe-doctest#haxe
HaxeFoundation have switched to use utest, based off Franco's library, and latest haxe-doctest support this. But you can use munit or a tink one lots are supported by haxe-doctest.
It's quite easy to setup in my case geom/GeomTest.hx
So far I have only implemented some tests in one class still very much work in progress library, but already helped clarify my thoughts, and document aspects of my library as it progresses. /geom/Matrix1x2.hx
Then to run my tests:

#    Cppia test
-cp src
-lib utest
-lib haxe-doctest
-lib equals
-main geom.GeomTest
-cppia geomTest.cppia
-cmd haxelib run hxcpp geomTest.cppia
