ScriptCs Templating Support


If you havn’t yet heard about ScriptCs, it is not too late. Go here 

I just checked in a ScriptCs Templating module to integrate Razor and StringTemplate transformations in ScriptCs workflow. ScrtipCs Templating module can apply a Razor or StringTemplate (ST4) template on top of one or more model files (normally an xml file or json file), for scenarios like code generation or templating. Example below.

The first bits are

Installing template module

  • Install scriptcs. You need to install the nightly build using Chocoloately - cinst scriptcs -pre -source (Refer if you don't understand this)
  • Clone the repo at or download the source code from there.
  • Open the solution and build it in Visual Studio.
  • From the command line create a package: nuget pack -version 0.1.0-alpha
  • In VS, edit your Nuget package sources (Tools->Library Package Manager->Settings) and add the folder where the package lives locally.
  • Install the template package globally: scriptcs -install ScriptCs.Engine.Templating -g -pre

Rendering a template

  • Note that what ever you pass after -- will goto the module as it's arguments.
  • Run scriptcs with your template, file specifying our template module using -modules switch: scriptcs mytemplate.cst -loglevel debug -modules template - The -modules template argument let scriptcs load our template module.
  • Check the log output for details.
  • You can specify the output file using the -out switch -scriptcs mytemplate.cst -modules template -- -out result.txt (The parameters after -- are the template module parameters according to ScriptCs convention)

Rendering a template Using Models

Template module automagically converts xml files/urls and json files/urls to dynamic models that can be used from your template. Technically, it creates a C# fleuent dynamic object that wraps the xml/json.

Quick example: Create a new folder, and create a model.xml file inside that.

<class name="MyClass1">
  <property name="MyProperty1" type="string"/>
  <property name="MyProperty2" type="string"/>
  <class name="MyClass2">
    <property name="MyProperty1" type="string"/>
    <property name="MyProperty2" type="string"/>

Now, create your template, and save it as template.cst - Let us use razor syntax.

@model dynamic

@foreach(var item in Model["class"])
   <p> is a class name</p>  

Now, you can run the transformation by specifying the model file, like this

scriptcs template.cst -modules template -- -xml model.xml -out result.txt

Let us rewrite the template to generate the class and properties from our XML model file

@model dynamic

@foreach(var c in Model["class"])
   @:class {

   foreach(var p in c["property"])
       @:public @p.type {get;set;}


Regenerate the result file and see.

Transforming multiple model files

You may specify multiple model files

scriptcs template.cst -modules template -- -xml model1.xml -out result1.txt -xml model2.xml -out result2.txt

You may also use Json files as the model

scriptcs template.cst -modules template -- -json model.json -out result.cs

Accessing models from templates

For converting XML files/data to a dynamic model object that'll be accessed from templates, ElasticObject is used. Refer

For converting Json files/data to a dynamic model object that'll be accessed from templates, DynamicJsonConverter is used. Refer

Template module command line

Example usages:

  • Render using template mytemplate.cst and ElasticObject dynamic model from model1.xml using Razor (Razor is default)
    •  scriptcs mytemplate.cst -modules template -- -xml model1.xml -out result1.txt
  • Do the same as above, but using vb as the template language
    • scriptcs mytemplate.vbt -modules template -- -vb -xml model1.xml -out result1.txt
  • Render using template mytemplate.st4 - Using StringTemplate instead of Razor
    • scriptcs mytemplate.st4 -modules template -- -st4 -xml model1.xml -out result1.txt

More tests need to be added, and St4 support is a bit untested. Happy Coding.

Top 7 Coding Standards & Guideline Documents For C#/.NET Developers

Some time back, I collated a list of 7 Must Read, Free EBooks for .NET Developers, and a lot of people found it useful. So, I thought about putting together a list of Coding Standard guidelines/checklists for .NET /C# developers as well.As you may already know, it is easy to come up with a document - the key is in implementing these standards in your organization, through methods like internal trainings, Peer Reviews, Check in policies, Automated code review tools etc. You can have a look at FxCop and/or StyleCop for automating the review process to some extent, and can customize the rules based on your requirements.Anyway, here is a list of some good Coding Standard Documents. They are useful not just from a review perspective - going through these documents can definitely help you and me to iron out few hidden glitches we might have in the programming portion of our brain. So, here we go, the listing is not in any specific order.1 – IDesign C# Coding StandardsIDesign C# coding stand…

5 Awesome Learning Resources For Programmers (To help you and your kids to grow the geek neurons)

Happy New Year, this is my first post in 2012. I’ll be sharing few awesome learning resources I’ve bookmarked, and will be pointing out some specific computer/programming related courses I've found interesting from these resources.Also, thought about saving this blog post for my kids as well - instead of investing in these Child education schemes (though they are too small as of today, 2 years and 60 days respectively ). Anyway, personally my new year resolution is to see as much videos from this course collections (assuming I can find some free time in between my regular job && changing my babies diapers).1 – Khan AcademyAs I mentioned some time back, you and your kids are missing some thing huge if you havn’t heard about Khan Academy.  It is an awesome learning resource, especially if you want to re-visit your basics in Math, Science etc.With a library of over 2,600 videos covering everything from arithmetic to physics, finance, and history and 268 practice exercises, th…

Hack Raspberry Pi – How To Build Apps In C#, WinForms and ASP.NET Using Mono In Pi

Recently I was doing a bit of R&D related to finding a viable, low cost platform for client nodes. Obviously, I came across Raspberry Pi, and found the same extremely interesting. Now, the missing piece of the puzzle was how to get going using C# and .NET in the Pi. C# is a great language, and there are a lot of C# developers out there in the wild who are interested in the Pi.In this article, I’ll just document my findings so far, and will explain how develop using C# leveraging Mono in a Raspberry Pi. Also, we’ll see how to write few minimal Windows Forms & ASP.NET applications in the Pie as well.Step 1: What is Raspberry Pi?Raspberry Pi is an ARM/Linux box for just ~ $30. It was introduced with a vision to teach basic computer science in schools. How ever, it got a lot of attention from hackers all around the world, as it is an awesome low cost platform to hack and experiment cool ideas as Pi is almost a full fledged computer.  More About R-Pi From Wikipedia.The Raspberry Pi
