When can I use which variable substitution

I'm struggling a bit with this - perhaps I'm not finding the right place in the docs - but could we have a simple guide to what variable substitution works when.

My particular interest is in what works in the .yml - but generically it would be helpful to have a list of variables and the contexts in which they can be used.

As a specific example, it would be nice to use say build or version in number artifact names when zipping an entire folder.

   Yes, you can use $(environment-variable-name) in "Deployment name" of artifact definition that will be used as a zip file name if specified. The list of AV environment variables is here: http://www.appveyor.com/docs/environment-variables

   Let me know if you have any questions.

   Thanks for addressing the specific, unfortunately that doesn't quite work (I can guess why):

   If I put:

   artifacts:
     - path: publish
       name: appveyor.$(APPVEYOR_VERSION_NUMBER)
   

   In my .yml I get an artefact called AppVeyor..zip which is not quite what I had in mind!

   To get the answer to the question I actually asked... it would be nice to have a table that showed the same list as you have for environment variables that also includes the one valid for substitution with {valuename} and then a list of places where we can use {valuename}

   I see. I will check why environment variable is not evaluated in artifact "name".

   Those ones in curly braces - there are only two of them {build} and {version} and they work in assembly patching and "version" sections only. These variables have been in AV from day one and left for backward compatibility. Sorry for that confusion.
