Is it possible to make a T4 template output to be merged with an existing file? For example, if a T4 template generates localization resource XML files, is it possible to merge them in some existing resource file? You can get access to the underlying string builder the the T4 uses thought the GenerationEnvironment property. So by adding something like the following to your T4 you should be able to get a workable solution; <#@ template debug="false" hostspecific="false" language="C#" #> <#@ output extension=".txt" #> <#@ Import Namespace="System.IO" #> Line #<#= rand.Next(0, 100).ToString() #>

Project contains annotation processor which generates java code during compilation. By default, gradle outputs generated source files into build/classes directory. That causes some problems with discovery of newly generated source files by IntelliJ. Is there any straightforward way of configuring gradle to output source files into another directory? For example $buildDir/gen/main/java or $buildDir/build/generated/main/java ? There is an option for java compiler which allows to customize output directory for generated java sources ( documentation ). -s dir Specify the directory where to place

I have a class A and B.M extends A. Now I want a create a constructor of B using code generation option of eclipse which accepts parameters and set values of all fields of B (I mean it should also set fields inherited from A). Is there any shortcut to generate such code in eclipse? Right click in the editor and click "Source -> Generate Constructor using Fields". You can select the super constructor to use and also select instance variables to add to the constructor. Eclipse (3.5) has no built in option for that particular case, but I would anyway suggest that you have a separate constructor

With jOOQ , I may want to combine using the jOOQ code generator with Maven and a custom generator strategy . It looks as though this can be done as such (leaving out irrelevant parts): <plugin> <groupId>org.jooq</groupId> <artifactId>jooq-codegen-maven</artifactId> <version>2.2.2</version> <!-- The plugin should hook into the generate goal --> <executions> <execution> <goals> <goal>generate</goal> </goals> </execution> </executions> <configuration> <generator> <name>org.jooq.util.DefaultGenerator</name> <!-- But the custom strategy is not yet compiled --> <strategy> <name>com.example

System.Xml.Serialization.XmlCodeExporter generates code (in code CodeDom form) from an XSD schema. But it does it with some quirks. For example an optional element: <xs:element name="Something" type="xs:decimal" minOccurs="0" maxOccurs="1"/> I would expect this to generate a corresponding code member of type Nullable<decimal> , but it actually creates a member of type decimal , and then a separate SomethingSpecified field which should be toggled separately to indicate a null value. This is probably because the library is from before the introduction of nullable types, but it leads to really

I know the compiler can't convert an async lambda expression to an expression tree, but is it possible to generate the expression tree manually ? var expr = Expression.Lambda<Func<Task>>( // how do I use 'await' in the body here? ); var func = expr.Compile(); I can't find any method related to async or await in the Expression class, but perhaps there's another way? await involves significant compiler re-writing; the generated IL is quite dissimilar to the original C#, with variable hoisting (onto a class) and branching, tasks, continuations, etc. It certainly isn't something that can be
