I am on the quest of creating a compile_commands.json database from my IAR .ewp project. This would allow me to use intelligent LSP autocompletion (ccls) and proper semantic highlighting (vim-lsp-cxx-highlight) from my vim setup.
I understand that I could manually create a CMake file with the same setup as in the .ewp project file, but unfortunately all my co-workers use the IAR IDE. I would risk missing some important project setup changes made by my co-workers and me failing to update the .ewp. It'd be great if I could automatically parse the .ewp file to CMake, and hence create the commands database.
Anybody knows of a clever way of doing this? If not, how would I go creating a tool that does exactly that? It appears that by undefining the Clang compiler defines one could make ccls use of the IAR code-base at full strenght.
Use -jsondb option in IAR
> iarbuild.exe example.ewp -jsondb debug -output compile_commands.json

i want to move from using CMake to Premake for my current project, but im usig vim and the YCM plugin which is really great for making my setup like an IDE. However, the plugin needs compilation flags file which is produced when running CMake. Is there something for Premake to generate a file like that as well?
Premake does not do this in its current state (alpha 13). If you have some insights as to what is necessary for getting it to work, the best thing to do would be to submit a ticket in the issue tracker.
I'm afraid, if your new build system does not generate that compilation flags file (yet), you'll need to maintain your own (hand-crafted) one. You can find an example at https://github.com/Valloric/ycmd/blob/0e999dbee209ea79a522259816ce3a68b7d6cddc/examples/.ycm_extra_conf.py.
I would advice to have (at least) one per project rather than one generic one in your $HOME.
Although I have to admit, that it would be beneficial to get it created and in sync with the actual build system, I don't find it too troublesome to maintain it manually. At the end of the day it only contains the C++ standard you want to use, a set of preprocessor symbols and a set of both system and user include directories.
I saw that there is a lua plugin for eclipse and there is a docpage on the awesome main page api_doc and all the .lua files in /usr/share/awesome/lib.
So I thought it must be possible to create a Library or Execution Environment so that one has tabcompletion and docview.
So I tried making my own Execution Environment:
wrote the standard .rockspec file
downloaded the documentation made an ofline version of it and put it in docs/ folder
ziped the files and folders in /usr/share/awesome/lib
ziped all up
tried it out ... and it failed.
When I try to view a documentaion for a .lua file I get "Note: This element has no attached documentation."
Questions: Am I totaly wrong in my doing (because I have the feeling I am)? Is there any way to edit the rc.lua with tabcompletion and docview?
Koneki will probably take a while to setup, but it's definitly worth it. Going for the".doclua"(by using version 1.2) would certainly make it, but I doubt that using a script to generate the information you need, would work out on the long run.
Most likely, you'll probably pass a bit of time to define what kind of object you're dealing with every time you come across one. The right to do, would be to actually take the time to see if the object/module/inner type inherit from an another object, so can actually have more completion feature as you keep using autocomplete to go from one object to another by pressing "dot"+ctrl_space.
In an ideal world, one person could probably make it right and share to other, so they can enjoy a full featured autocomplete editor.
Found solution for eclipse.
First off the idea of setting up an Execution environment was the wrong one.
So the whole thing about downloading the doc although.
For more information on that visit eclipse Wiki for LUA Development Tool.
The right thing to do is to add a source folder which contains the /usr/share/awesome/lib directory.
The bad news is that my comment from above was totally right, which means one has to configure each .lib file in /usr/share/awesome/lib to meet the requirements of the Documentation Language described here.
Than editing the rc.lua (which one can add to the project in eclipse) works with tabcompletion and doc view.
Since the Documentation Language used in the lib files is similar to the one used by "LUA Development Tool" one has not to change many things. Maybe there are even scripts for that.
I'm trying to get the compilation args for each compilation unit so I can create the "compilation_commands.json" for my vcxproj that can be used with clang's libTooling.
The libTooling tutorial suggests using a CompilationDatabase to provide the compilation args for all the cpp files in a project. The tutorial shows that CMake can generate the compilation_commands.json for CMake based projects.
Since clang can be put into "MSVC mode" via clang.exe --driver-mode=cl or clang-cl.exe my thought was if I could get the compilation args for each cpp file in my VS2012 project I can create the compilation_commands.json for a vcxproj.
However I'm having trouble finding APIs in the VS2012 SDK that walks a vcxproj and retrieves the compilation args for each compilation unit. Can someone point me towards the right APIs?
I know this is really old, but the question is still relevant, so for those still looking for an answer, I managed to finally do this recently using this little VS extension.
Just install it and a new 'Sourcetrail' menu will appear, with a 'Create Compilation Database' entry (I found Intellisense needs to be enabled for it to be clickable). That will let you customize what to include and generate a compile_commands.json that you can use with other clang-based tools, etc.
It is a DIY job. The VS IDE projects have properties for each .cpp file. By selecting a .cpp, then right-click -> Properties -> Config properties -> C/C++ -> Command-Line you have the options required to compile that specific file. The 64 dollar question is how to do it for every file in the project / solution. The answer is not trivial, but it is doable. At least I did it on VS 2010 and I'm pretty sure it works on VS 2012/3
The secret lies with what is called VCEngine. It is a tool that evaluates all the properties or the files in the project. So the real problem is how to evaluate the property "Command Line" for each file. You need to iterate through all the .cpp files and call VCProject's Evaluate method for the "Command Line" property.
The simplest way I think you can do it is to write a plugin for the VS IDE and thus gain access to the VCEngine instance. There are plenty of examples of how to do that. Be aware that the VCEngine is version dependent.
Anywhay, for projects/solutions with thousands of .cpp files, you need to automate the compilation database creation.
When I'll have time I will put the solution on github

I want to make a few little changes to an open source flash charts library.
In the source there are .fla files and .as files. After editing one of the .as files,
I want to recompile, but I don't know how to do this. The charts library is dv charts.
I googled and found this topic here: stackoverflow topic. I tried using mxmlc as described, but that comes with the error
bash: ./mxmlc: /bin/sh^M: bad interpreter: No such file or directory
So I want to know if there's an easy way to recompile after making a few changes to the actionscript files? Should I use mxmlc or are there any alternatives.. ?
Thanks!
If you can use a virtualization software, I'd say FlashDevelop. It can't recompile your FLA, only your AS classes though.

Cheers,

If you're writing from scratch you can us MXMLC to compile your actionscript with the open-source Flex SDK - since you have revisions to an FLA you need an actual version of Flash Pro to compile those. Your best bet, if this is a continuing project would be to save out your assets to a SWC from Flash Pro then embed it into your AS project that way. From there, you can use MXMLC to compile your project.
I come from a Java background, and the shop where I currently work refuses to use anything other than MS VC++ to build their legacy project. They don't appear to use any standards for setting up their build environment other than just building it using VS2005 and clicking the compile button.
I was wondering if there was anything closer to what Java had for instance:
A build tool like ANT or Maven
A directory structure that makes sense containing
src - Place for all my source files .c/.cpp/.h
lib - A place for any libraries that might be used in the project (.dll, .lib)
dist - A place for the output executable/distribution of the project
resources - A place for any images/sounds/text files that might be included in the project.
build.xml - Some sort of a build file (my guess would be something like ./configure or MAKEFILE)
Or am I asking too much from a C++ build environment? Is it just always as chaotic as the people in my shop make it out to be? I really have a hard time believing that considering the success of so many C++ projects on the internet.
It sounds like you have good intentions - coming form a non MSVC world I can see your points.
If I were in y our shoes I would definitely make a command line/automated build/build server.
You can use MSBuild for this - and hudson has a plugin for this. I usually have a "Build" directory near the root of the projects that contains scripts/etc that will call the appropriate MSBuild/.sln files.
The "makefiles" for Visual Studio are .sln and .vcproj files. You can call those with msbuild from the command line. You can also export a makefile (I think that is still an option) from within the IDE that you can run. I don;t recommend going that route though other than trying it out and seeing what is output - since that is what you are familiar with.
Both the vcproj and sln files are human readable - go through them - it will give you some useful information.
I would also agree that having a distributon directory is good - for building an installer/etc after the build. Copy all the needed binaries there - either in postbuild steps or in another script/etc.
Let us know what you end up doing.
I have one other piece of advice:
UPGRADE to VC/Dev studio 2008 or 2010. ASAP
MSVC does not impose any directory structure on you. There are some defaults, as mentioned above for the Debug and Release directories, for example, but even these can be overridden on a per-project basis. Use whatever directory structure makes sense to you.
Visual Studio does provide command line support if you don't want to use the IDE. See This MSDN Article for more information.
You can setup a proper build environment using Visual Studio (and for solutions with more than one project, you should), and there are a number of environment variables to use in the project configuration to set so that output files and intermediate files go to different folders than those defined by default.
In our large VS solution, we use e.g. obj/$(ProjectName)/$(ConfigurationName) as intermediate directory and bin/$(ConfigurationName) as output directory in all sub-projects.
All these things must be enforced by the user, and it seems that no single recommendation/best practice has evolved.
The standardized stuff:
The build tool: Visual Studio (doesn't need an extra product)
Build file: *.sln / *.vcproj (*.vbproj for Visual Basic, etc)
Directory structure: "Debug" and "Release" directories for the output binaries.
The rest isn't so much "chaotic" as "doesn't really matter". "Chaotic" suggests that it changes all the time, but in reality you just pick one for a project and stick with it. Companies may have internal standards across projects. It just doesn't matter enough to bother standardizing across companies. C++ is a complex language anyway; anyone with sufficient IQ to read C++ can deal with reasonable variation. The difference between \lib\ and \Library\ won't stop them.
