What is Code GenerationWhat is Code Generation• Software creation• Can be fun and challenging• …but also repetitive and monotonous• Repetition & monotony leads to bugs
• Code generation is not a new concept• With most tools you don’t control the output• Often viewed as a “Black Box” solution• Ex, data layer created (but it is not your code)
• CodeSmith 3.0• Not a “Black Box” solution• Template driven code generation (it is your code)• Use existing templates or write new ones

Active & Passive GenerationActive & Passive Generation• Passive Generation• Use CodeSmith as “key stroke” saver• Render template and then use results• CodeSmith may or may not be used again
• Active Generation (Recommended)• Use template as source code• Whenever build project run template• Ex, write single template to generate 100s
of classes (or other files)

Active Generation TemplatesActive Generation Templates• Enabled through Visual Studio Custom Tool
• “Active Generation Templates”• Executed each time the input file changes• Perfect for Active Generation• Example: SampleProjects\CSharpCodeGeneratorSample
• Execute Active Generation Templates• Right-click hashtable.xml in VS .NET• Select ‘Run Custom Tool’• Renders multiple property sets for template• Any time xml file is touched templates are regenerated• Click on show all files to see hidden code files

Creating Data Access LayerCreating Data Access Layer• Stored Procedures (SPROC)• Preferred data access technique• Provides abstraction API for data access
• Create/Read/Update/Delete (CRUD)• Tedious to write (Equals more bugs)• Imagine manually creating for every table
• StoredProcedures.cst Template• Generates CRUD layer for any table• Created in seconds! …for all tables

Building Data Access APIsBuilding Data Access APIs• Data Access Layer• APIs for working with data APIs, e.g. sprocs• Typically monotonous repetitive code• Time consuming to code by hand
• Encourages Stored Procedures• Template generates typed wrapper• VB.NET and C#
• Enforces best practices• Open connection late, close early• Try/Catch blocks

Database DocumentationDatabase Documentation• DbDocumenter Templates (master.cst)• Set basic information and run batch file• Ex, database connection and title
• Great demo of CodeSmith capabilities• Simple repetitive problem• Would take weeks to create manually• Demonstrates CodeSmith “best practices”
• Additional ideas…• Modify templates to generate ASP.NET• Generate .CHM help files• Add execute capabilities, etc.

Advanced Tips & TricksAdvanced Tips & Tricks
Debugging TemplatesDebugging Templates• Set Debugger.Break() in code• Break-point in Template execution• .NET JIT Debugger window opens
• From .NET JIT Debugger window• Select Debug Tool• EX, Visual Studio .NET 2003
• Step through template source• Reports error in template directly• Most tools allow debugging of the result
• Set Debugger.Break() in code• Break-point in Template execution• .NET JIT Debugger window opens

• Step through template source• Reports error in template directly• Most tools allow debugging of the result
Debugging Templates, contDebugging Templates, cont• Compilation is similar to ASP.NET• Occasionally template is not enough• Need the ability to examine source
• LinePragmas• Defined in <%@ CodeTemplate %>• Set to true or false
• Default to true• Reports line number in template• False, reports line number in generated code

Template Events & OverridesTemplate Events & Overrides• Initialization events• Called once when template is instantiated
• OnInit• Called once when template is instantiated• All other events are raised on each use
• ParseDefaultValue()• Allows for handling of type conversions• Called for every default value of a property
• GetFileName()• Override the default output file name

• GetFileName()• Override the default output file name
Template Events & OverridesTemplate Events & Overrides• ‘Render’ events
• Similar in concept to ASP.NET events• Called each time template instance is rendered
• OnPreRender• Called before template rendering begins• Set up default state
• Render• If overridden takes over rendering process• Example, if you want a ‘master’ template
• OnPostRender• Called after template is executed• Contains string result of rendered template
