• domain specific languages and compilers

  - by hyperboreean

  I was looking over Martin Fowler's recent book contents - Domain Specific Languages and I noticed some ANTLR example - that got me thinking that writing compilers will become more and more popular since people needs in this matter will increase. So, will the compiler theory still be as arid (being subjective here) as it was until now or are there any chances that we'll get more applied, programmer oriented materials ?

• The ternary (conditional) operator in C

  - by Bongali Babu

  What is the need for the conditional operator? Functionally it is redundant, since it implements an if-else construct. If the conditional operator is more efficient than the equivalent if-else assignment, why can't if-else be interpreted more efficiently by the compiler?

• Pure Actionscript 3 Adobe Air Application main class constructor not being called

  - by SilverCode

  I'm writing an Air application using only Actionscript, and Flex3 SDK as the compiler. Everything compiles and runs fine under adl, but when the final air file is built and installed, the main class is never initialized. For instance: package { import flash.display.Sprite; public class main extends Sprite { public function main() { trace("Init"); } } } When run under ADL, "Init" will be output to the console, but when installed and run, nothing happens (the constructor for class main is never called).

• Opt-out of copy constructor

  - by sheepsimulator

  This might be a silly question, but... I've been writing a number of classes that utilize non-copyable members. These classes are never initialized via the copy constructor in my source. When I try to compile without supplying my own copy-constructor, g++ throws out many errors about how it can't build a default copy constructor, due to the non-copyable member objects. Is there a way to tell the compiler to just not give me a copy constructor?

• HttpOnly cookies on google app engine java

  - by Spines

  Anyone know how I can use httponly cookies for sessions and cookies on the app engine? In the javadoc for the Cookie class, http://java.sun.com/javaee/6/docs/api/javax/servlet/http/Cookie.html#setHttpOnly(boolean) , there is a setHttpOnly method. I get a compiler error when trying to use it when developing for app engine though. The method was introduced in the Servlet 3.0 spec, so its pretty new.

• Publish MVC v1 C# application through Cruise Control

  - by Jonathan

  I am attempting to publish a 3.5 MVC website on my build server through cruise control. Having looked around on the net it appears you need to wrap the ASP Net Compiler. I was hoping that this task can be called through MSBuild. Any ideas on how this is done?

• A guide to Boo's metaprogramming and extensibility features?

  - by Mike K

  I'm interested in learning about Boo's more powerful features such as syntactic macros, parser support (Ometa?), compiler pipeline, etc. My impression is that these areas have been in flux and somewhat under-documented. Are there any good resources for learning about these things other than studying the source code?

• good/full Boot Spirit examples using version 2 syntax

  - by bpw1621

  Almost all of the examples I've gone and looked at so far from: http://boost-spirit.com/repository/applications/show_contents.php use the old syntax. I've read and re-read the actual documentation at http://www.boost.org/doc/libs/1_42_0/libs/spirit/doc/html/index.html and the examples therein. I know Joel is starting a compiler series on the blog http://boost-spirit.com/home/ but that hasn't gotten in full swing yet. Any other resources to see worked examples using some more sophisticated/involved aspects in the context of fully working applications?

  - by Matt

  Hey all, I was wondering if there is some variable that will return what $_SERVER['DOCUMENT_ROOT'] returns when I call PHP like this: ./somescript If not, how do people get around this case? I'm looking to be able to call the same script (a template compiler) in both the web browser and the terminal. Thanks! Matt Mueller

• If NSString stringWithContentsOfFile is deprecated, what is its replacement?

  - by mobibob

  I have some sample code from Tuaw which is probably 3 releases old ;) The compiler is issuing a warning that the method is deprecated, but I do not see that mentioned in the SDK docs. If it is deprecated, there must be an alternative approach or replacement method. Does anyone know what the replacement is for this method?

• Objective C: Initalizing static variable with static method call

  - by adranale

  The Compiler claims an error saying: "initializer element is not constant", when I try to initialize a static variable inside a method with a call to a static method (with + in its definition). Anyway I can tell him that this method always returns the same value. I know this is not the same as static method, but there seems to be no constant methods in Objective-C (other than macros which won't work here because I am calling UI_USER_INTERFACE_IDIOM() from inside the method).

• MXMLC and 64bit JRE

  - by sascha

  Are there any workarounds to get the Flex compiler to work with a 64bit JRE? If I use an MXMLC task in an Ant buildfile in Eclipse it works fine but if I try to use MXMLC from the command line (or try the Run... command from FDT in Eclipse) it fails, telling me ... "Error loading: C:\Program Files\Java\jrrt-1.6.0\jre\bin\jrockit\jvm.dll" (this is with a 64bit JRockit runtime but that shouldn't matter).

• googletest and EXPECT_THROW weirdness

  - by thumper

  I have a class that has no default constructor, but the construct may throw. I was wanting to have a test like: EXPECT_THROW(MyClass(param), std::runtime_error); But the compiler, g++, complains that there is no default constructor for Myclass. However the following: EXPECT_THROW(MyClass foo(param), std::runtime_error); Works, and the test passes as expected. Why though won't googletest accept the temporary object?

• Building DLL via Maven with mojo-native

  - by graham.reeds

  I can build a simple dll consisting of a source file, a header file and a definition but now I am progressing beyond a simple toy dll and working towards something more complex. The DLL I am trying to compile has 2 source files, 2 headers and the dreaded stdafx pair. To compile normally you would use /Yc to compile the pch and /Yu to use it. How do you specify that with in the constraints of mojo-native's compiler options?
