My intention is to have own naming rules in eclipse editor for C programming
Ex: a function should start with File name, it shall contain maximum of 20 character- FILENAME_MaxOf20Char().
When it is violated has to show an warning.
To do this tried to extend org.eclipse.cdt.core.IErrorParser. But this one is parsing from compilor output.
IErrorParser is not the right extension point to use for this.
You want to use the Code Analysis (CodAn) framework and write a custom checker. See this page for documentation.
I'm developing a Modelica library and need to produce a document with source code listings. I'd like to be able to include the source of the Modelica models without annotations.
I could manually edit them out, but I'm looking for a more automated strategy. I'm guessing the most convenient and straightforward approach is to use some tool to save .mo files with no annotations and include those in my document (I'm using \lstinputlisting in LaTeX).
Is it possible to do this? I have access to Dymola, OpenModelica and JModelica. Dymola is obviously capable of producing such a listing, as it's able to include it in the automatically generated documentation (File > Export > HTML...). I've been looking into scripting with Dymola and OpenModelica, but haven't found a way to do this either.
JModelica seems like it could be a good option, but I don't have experience working with Python. If this is possible and someone gives me some pointers, I'm willing to look into it myself. I found a mention to a prettyprint function that might do the job, but I'm not sure where to start. I can't even find reference to that function in the latest documentation.
It would also be more convenient for me to find a way of doing it with Dymola/OpenModelica (whether through the UI or by using a script). Have I missed something?
I think you could use saveTotalModel("total.mo", MyModelName) in OpenModelica. This will strip most annotations (not ones used for code generation if I remember correctly) and pretty-print the source code including all dependencies. Then you just copy-paste the models/packages that you want to include in the listing. Or if you prefer, you can do something like the following to only include code for a particular model:
loadModel(Modelica);
loadFile("MyModel.mo");
saveTotalModel("total.mo", MyModel.A.B);
clear();
loadFile(MyModel);
str := list(MyModel.A.B);
writeFile("MyModel.A.B.listing", str);
I'm learning Elixir and attempting to use the elixir-mongo library. During the auth/1 command, A the function uses Server.call, piping in the MongoDB request string. looking at the Mongo.Server class, it does not appear to be an actual genserver, nor have a method to match call/1. How is this working?
With high probability it doesn't work. Mongo.Server module doesn't export call function. There are no macros that generate it magically. My guess is that master branch is currently broken. If you are using the library and want to dig into the sources make sure you are looking at the same tag as the version you are using in your project.
Also, there are no classes and methods in Elixir. There are modules and functions :)
I have use semantic-analyze-proto-impl-toggle to switch between the function's proto and impl, but when I use this feature it always doesn't do anything except saying that it can't find correspongding implement, the other feature like name completion is OK.Can anyone help me on this issue? And I really eager to know whether the semantic only parse the current buffer and the header files in include path, not parsing other implement files. I mean that whether semantic parses all the file in the project when it try to find the implement of a function.
The proto/impl toggle will look for symbols in all the files of your project that have been parsed so far. It runs into trouble when the sources don't have the right includes and you try to jump between methods. There is an explanation, with a hacky work-around patch on the mailing list here:

This is a little convoluted, but lets try:
I'm integrating LUA scripting into my game engine, and I've done this in the past on win32 in an elegant way. On win32 all I did was to mark all of the functions I wanted to expose to LUA as export functions. Then, to integrate them into LUA, I'd parse the PE header of the executable, unmangle the names, parse the parameters and such, then register them with my LUA runtime. This allowed me to avoid manually registering every function individually just to expose them to LUA.
Now, flash forward to today where I'm working on the iPhone. I've looked through some Unix stuff and I've gotten very close to taking a similar approach, however I'm not sure it will actually work.
I'm not entirely familiar with Unix, but here is what I have so far on iPhone:
Step 1: Query for the executable path through objective-C and get the path of my app
Step 2: Use dlopen to get a handle to my app using: `dlopen(path, RTLD_NOW)`
Step 3: Use `dlsym( libraryHandle, objectName )` to attempt to get the address of a known symbol.
The above steps won't actually get me to where I want to be, but even that doesn't work. Does anyone have any experience doing this type of thing on Unix? Are there any headers or functions I can google to put me on the right track?
Thanks;)
iPhone does not support dynamic linking after the initital application launch. While what you want to do does not actually require linking in any new application TEXT, it would not shock me to find out that some of the dl* functions do not behave as expected.
You may be able to write some platform specific code, but I recommend using a technique developed by the various BSDs called linker sets. Bascially you annotate the functions you want to do something with (just like you currently mark them for export). Through some preprocessor magic they store the annotations, sometimes in an extra segment in the binary image, then have code that grabs that data and enumerates its. So you simply add all the functions you want into the linker set, then walk through the linker set and register all the functions in it with lua.
I know people have gotten this stuff up and running on Windows and Linux, I have used it on Mac OS X and various *BSDs. I am linking the FreeBSD linker_set implementation, but I have not personally seen the Windows implementation.
You need to pass --export-dynamic to the linker (via -Wl,--export-dynamic).
Note: This is for Linux, but could be a starting point for your search.

If static linking is an option, integrate that into the linker script. Before linking, do "nm" on all object files, extract the global symbols, and generate a C file containing a (preferably sorted/hashed) mapping of all symbol names to symbol values:
struct symbol{ char* name; void * value } symbols = [
{"foo", foo},
{"bar", bar},
...
{0,0}};
If you want to be selective in what you expose, it might be easiest to implement a naming schema, e.g. prefixing all functions/methods with Lua_.
Alternatively, you can create a trivial macro,
#define ForLua(X) X
and then grep the sources for ForLua, to select the symbols that you want to incorporate.
You could just generate a mapfile and use that instead, no?
