T4 code generation without Visual Studio 2010?

阅读更多关于 T4 code generation without Visual Studio 2010?

Is it possible to run T4 code generation without needing Visual Studio 2010? Basically I have to build an in house ORM (don't ask..if I had a choice I wouldn't). I was planning to use subsonic as a base but change some things and how they work. However my main question is can I run T4 from an external application that I write, so I can use the features of T4? Or am I better off doing it myself (which I doubt)? Michael Maddox TextTransform.exe will do what you want for simple scenarios: http://msdn.microsoft.com/en-us/library/bb126245.aspx Here is how to run a T4 template from your own code for

How to efficiently implement closures in LLVM IR?

阅读更多关于 How to efficiently implement closures in LLVM IR?

问题 I started adding closures (lambdas) to my language that uses LLVM as the backend. I have implemented them for simple cases where they can be always inlined i.e. code for the closure definition itself doesn't need to be generated, as it is inlined where used. But how to generate the code for a closure in case the closure isn't always inlined (for example, it is passed to another function that isn't inlined). Preferably, the call sites shouldn't care whether they are passed regular functions or

Dynamic code generation

I am currently developing an application where you can create "programs" with it without writing source code, just click&play if you like. Now the question is how do I generate an executable program from my data model. There are many possibilities but I am not sure which one is the best for me. I need to generate assemblies with classes and namespace and everything which can be part of the application. CodeDOM class: I heard of lots of limitations and bugs of this class. I need to create attributes on method parameters and return values. Is this supported? Create C# source code

I'm trying to create a custom tool for code generation in Visual Studio 2010. First I register it: "$(FrameworkSDKDir)Bin\NETFX 4.0 Tools\gacutil.exe" /if "$(TargetPath)" Then I add it via a reg key: [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\VisualStudio\10.0\CLSID\{6A96476E-74F3-4AB3-9CCA-F15EC6104D84}] "RuntimeVersion"="v4.0.30319" "Class"="MapBuildTool.MapFileGenerator" "Assembly"="MapBuildTool, Version=1.0.0.0, Culture=en-US, PublicKeyToken=7d8abca94a1e38ae" "ThreadingModel"="Both" "InprocServer32"="C:\\Windows\\SysWOW64\\mscoree.dll" @="MapBuildTool" [HKEY_LOCAL_MACHINE\SOFTWARE

How to create Clojure `defn` functions automatically without macros?

阅读更多关于 How to create Clojure `defn` functions automatically without macros?

问题 Originally motivated by the following question: Mapped calls to clojurescript macro Suppose you want to create many similar functions automatically (i.e. without hand-writing them all). Suppose we have some pre-existing functions and we want wrap them with handlers for a callback of some sort: (defn do-foo [] (println "I foo'ed")) (defn do-bar [] (println "I bar'ed")) (defn do-baz [] (println "I baz'ed")) (defn manual-on-foo [] (do-foo)) (defn manual-on-bar [] (do-bar)) (defn manual-on-baz []

JIBX: Classes generated from maven codegen plugin : No unmarshaller for element

问题 I use Jibx CodeGen maven Plugin to generate java sources and binding from xsd files. I want to maintain several versions of the xsd in the same applications so I plan to generate to a different target package depending the version of the XSD. JBix seems to generate java package based on the namespaces of the xsd files. ie. for namespace http://www.example.jibx.org/generated/v30/types it generates package org.jibx.example.generated.v30.types During maven build code generation seems to work and

Visual Studio XSD Tool: Generate Collections Rather Than Arrays

阅读更多关于 Visual Studio XSD Tool: Generate Collections Rather Than Arrays

I generated some C# classes from an XSD using the Visual Studio XSD utility and it generated arrays for storing a collection of elements, rather than one of the built-in generic Collection<T> (or related) classes. None of the command line parameters mentioned in xsd /? mention anything about generating collections rather than arrays, but I know that this can be done with web service proxy classes that Visual Studio generates, so I figured it must be possible. Does anybody know how to have the XSD utility generate collection classes rather than arrays? Found this post when searching for an

问题 I am using rtwbuild to generated C++ code from a Simulation diagrams and would like to save generated code to an arbitrary directory. Is there any way to do so? 回答1: You can control the folder for generated files in 3 different ways. You can set the "Code generation folder" option in Simulink Preferences. You can reach to Simulink preferences from any model using File menu and then choosing Simulink Preferences. This will change the code generation location for all models and will persist

functions vs repeated code

I am writing some PHP code to create PDFs using the FPDF library. And I basically use the same 4 lines of code to print every line of the document. I was wondering which is more efficient, repeating these 4 lines over and over, or would making it into a function be better? I'm curious because it feels like a function would have a larger overhead becuse the function would only be 4 lines long. The code I am questioning looks like this: $pdf->checkIfPageBreakNeeded($lineheight * 2, true); $text = ' label'; $pdf->MultiCell(0, $lineheight, $text, 1, 'L', 1); $text = $valueFromForm; $pdf->MultiCell
