Thanks Hern��n for your report.
As Sven said, it is not yet present in the stable version of NeoJSON.
But it should not matter as I load the bleeding-edge version.

I will look into this.
Can you tell me which script you used to load the tool? Is it the one in the first e-mail?

Hi Skip,

Trying your tool in Windows 8.1 and Pharo 5. I wrote my username and password and this is what I get:

MessageNotUnderstood: NeoJSONObjectMapping>>allowNil
(there is no implementor of #allowNil)

Cheers,

Hern��n

Hi everyone,

I am announcing a new version for the API bindings to GitHub in Pharo.
For documentation and information on how to load it, see the new project homepage:

https://balletie.github.io/GitHub/ (generated with Pillar. Plug for Damien and Cyril)

For a list of changes in this release, follow this link: https://github.com/Balletie/GitHub/releases/tag/v0.5

To load absolutely everything, including the tests and the tool, evaluate:

Metacello new
    baseline: 'GitHub';
    load: #(tests tool)

If you have loaded the tool, it can be opened via the world menu, under ���Tools���.

Feedback welcome :)
