Getting started

Chocolatey install: 

(apt-get/homebrew for windows)

                    @powershell -NoProfile -ExecutionPolicy Unrestricted -Command "iex ((New-Object Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))" && SET PATH=%PATH%;%systemdrive%\chocolatey\bin
                    

Scriptcs install (using chocolatey):

                    cinst scriptcs
                    

Demo: repl + Helloworld.csx

script code semantics

• no top-level class/Main method
• no script namespaces
• global functions allowed
• MODULES, ASSEMBLIES LOADED AUTOMATICALLY/BY CONVENTION
• #load directive to load script from script
  
• #r directive to reference an assembly from script
• SCRIPT PACKS ACCESSIBLE THROUGH REQUIRE<T>

Scriptcs.request script pack (1/2)

using ...
namespace ScriptCs.Request
{
    public class Request : IScriptPackContext
    {
        public HttpResponseMessage PostJson<T>(string url, T objectToPost) where T : class
        {
            var httpClient = new HttpClient();
            var bodyContent = new StringContent(JsonConvert.SerializeObject(objectToPost), Encoding.UTF8, "application/json");
            httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
            return httpClient.PostAsync(url, bodyContent).Result;
        }
    }
}
    

SCRIPTCS.REQUEST SCRIPT PACK (2/2)

namespace ScriptCs.Request
{
    public class ScriptPack : IScriptPack
    {
        IScriptPackContext IScriptPack.GetContext()
        {
            //context to be used in scripts
            return new Request();
        }

        void IScriptPack.Initialize(IScriptPackSession session)
        {
            session.AddReference("System.Net.Http");
            session.ImportNamespace("System.Net.Http");
            session.ImportNamespace("Newtonsoft.Json");
        }

        void IScriptPack.Terminate()
        {
            //Cleanup any resources here
        }
    }
}
