I designed a small DSL in Xtext and wrote a sample DSL application that is successfully converted to C++ code by using Xtend code generator. What I would like is to be able to click "Run" inside Eclipse and then to automatically compile the generated .cpp file and run it. How to do it?
The first what comes in my mind is to install the CDT plugin and get C++ sources compiled, generally.
Then, you may add the CDT nature to your project where the. C++ code was generated in.
After that, use the CDT menu actions to compile and run the code.

I want to use the eclipse cdt api to resolve c++ code AST tree for code analysis.
base on the blow question answer, I try to create a default Workspace and project by java code. The Workspace init method require many IDE source support, when i fix one resouce issue, another comes. is there any demo for this?
Using CDT without Eclipse
If you want to parser a single source file, it is enough to use cdt.core only. If you want to use the higher level(semantic) you need to replace a lot dependences about those IDE packages. I did a project using Eclipse-JDT and use JavaCore and Workspace to generate IJavaProject. It is similar with CDT. I also do some research about static-code-analysis using JDT/CDT.
I have a standard C project in Eclipse CDT. Naturally it uses make. I have decided to add some JSON support to my application to be able to load/save its configuration in a readable format that the user (if such desire occurs) can alter those manually and/or through an external tool. I've looked up two options so far namely Jansson and Json-C. The problem is that both are using cmake, which, if I recall correctly, can be imported in Eclipse CDT without problems (though in itself CDT can't create cmake projects).
I was thinking of adding a script for the pre-build step of my project that runs cmake (as an external command) and sets up the JSON library (static and/or dynamic) so that when the build process of my projects starts the library file will be available.
Is there a better way to combine a cmake with a make project in Eclipse CDT? I know that cmake basically generates a Makefile but I've never done such a combination before.
Even if there is a JSON C library somewhere out ther that uses make (I'm 99.9% sure there is such thing :D) I'd still like to know how to tackle this situation.
Part of a project I'm on has a GUI app that is built with Netbeans using the GUI design tools that come in that IDE.
But this is only part of a bigger project, and needs to be built in an environment that does not have Netbeans installed (it happens to be a Gradle-based build on Jenkins). I've gotten builds to (seemingly) work, but keep running into inexplicable run-time errors (i.e., dependencies appear to be met with identical jars on the classpath and so on, but attempts to read resources from the project jar fail.).
From googling around, it looks like this might have something to do with compiling .form files and then including some dependency for the resulting java. (though, the Netbeans build does not add any jars above what our gradle build adds).
So the question is... can this even be done? or does a proper build simply rely on some hidden build-time mojo that's going on in Netbeans?
Yes, you can compile the classes without NetBeans. Just be sure you do not any NetBeans library, like AbsoluteLayout. The .form files are for NetBeans showing you components with Matisse, but all the generated code will be in the .java file.
This question is not limited to lex and yacc, but how can I add a custom script compiler as part of a project? For example, I have the following files in the project:
grammar.y
grammar.l
test.script
The binary 'script_compiler' will be generated using grammar.y and grammar.l compiled by lex, yacc and g++. And then I want to use that generated script_compiler to compile test.script to generate CompiledScript.java. This file should be compiled along with the rest of the java files in the project. This setting is possible with XCode or make, but is it also possible with Eclipse alone? If not, how about together with Maven plugin?
(I might setup the script compiler as a separate project, but it would be nice if they can be put in the same project so that changes to the grammar files can be applied immediately)
Thanks in advance for your help!
You can add a custom "Builder" from the project properties dialog. This can be an ant script (with an optional target) or any other script or executable.
There are also maven plugins for ant and other scripting languages
If you just want to run an external program in Maven this is what you want: http://mojo.codehaus.org/exec-maven-plugin/ -- you can then run Maven targets from your IDE or command line and it should do the right thing either way.
To integrate with the normal compilation bind the plugin to the "generate-sources" phase and add the location where the Java files are generated to the "sourceRoot" option of the exec plugin. That way the compiler will pick them up.
Ideally you generate the code into a folder "target/generated-sources/MY_SCRIPT_NAME". That is the standard location for generated sources in the Maven world and e.g. IntelliJ IDEA will pick up source files inside of that location. Note that this doesn't work if the files are directly in "target/generated-sources".
The other option is to write your own Maven plugin, which is actually quite easy as well. See e.g. https://github.com/peterbecker/maven-code-generator
I have a project in Eclipse that currently has no ANT build file, but is about to have one created (to facilitate building jars). I'd like to write the build file so that it would work for both. I was just going to write the full build in ANT but I noticed this line in an IBM Help doc.
The Java builder runs the internal
Eclipse Java compiler which in turn is
responsible for indexing your source
so that searching, refactoring and
many other features are available.
Thus it is not possible to replace the
internal Eclipse Java compiler by
using a project builder. You can
disable the Java builder and you can
control when the Java Builder runs
with respect to the project builders
that you define.
Do I need to write the ANT file so that it conditionally compiles (javac) only outside Eclipse? Are there other things I need to do to make ANT and Eclipse play nicely together?
There are maybe more sophisticated approaches, but here's what works for me. Just set up your Java project in Eclipse to output classes to the same dir as your Ant buildfile does. Let Eclipse compile your project using normal Java compiler.
During typical development, you will probably be changing Java source files and wanting to see that they compile. The Eclipse Java compiler will take care of this. Less frequently you will need to rebuild jars. Ant will take care of that. You can kick off the Ant build when you need to from the command line or from Eclipse.
