I'm using the DIA SDK to get symbol information from .pdb files. For example, I want to use this to get a list of classes, functions, member variables, and so on from a project.
After some messing around I've been able to get this information, however I'm also getting a lot of extra stuff that isn't my own code but is added in after (by the standard library and such).
I've tried filtering this based on the source file of the given symbol, however get_sourceFileName() seems to be unreliable, usually not returning any value.
Any help would be appreciated, whether it's getting get_sourceFileName() to work properly or some other way of filtering out objects from code that isn't part of the project.
Note that I know there are alternatives to the DIA SDK that would make this easier, such as libclang, however those are not an option for this project for various reasons.
Is it possible to get access to / modify ColdFusion syntax trees at run time?
I'd wager not, and a 10 minute google search didn't find anything. Fiddling with closures and writing metadata dumps, we can see stringified versions of objects like [runtime expression], for example in the following:
function x(a=b+1) {}
WriteDump(getMetaData(x).parameters[1]["default"]);
Does it allow us to go no deeper than this, or perhaps someone knows how to keep digging and start walking trees?
Default UDF parameter expressions aren't available in function metadata as you've found. Other libraries that have implemented some form of CFML parser are
CFLint (written in Java and using ANTLR)
https://github.com/cflint/CFLint
CFFormat (also uses a binary compiled from Rust)
https://www.forgebox.io/view/commandbox-cfformat
Function LineNums (pure CFML)
https://www.forgebox.io/view/funclinenums
There is also a function callStackGet() docs: https://cfdocs.org/callstackget which might be useful to whatever you are trying to do.
And another CFML parser (written in CFML) here: https://github.com/foundeo/cfmlparser
I've inherited a large C++ project which I need to port to Linux. There are over 200,000 lines of source in this project spread across more than 300 files. It would be tremendously helpful to have a visual dependency/include tree to refer to for this project so that I can get a general feel for the application's internal structure. This would also help me to locate the "fault lines" between the core modules and Windows header files so that I can stub them out later.
The class viewer in Visual Studio simply isn't cutting it. I was reading around, and learned that Doxygen is a commonly used tool for listing dependencies. I'm much more of a visual person, and found that this wasn't so helpful. Fortunately, I learned about the Graphviz plugin, using something called "Dot" that has enabled me to generate dependency trees for parts. Unfortunately, hundreds of smaller dependency trees are generated for specific files, rather than having one large one as I'd hoped for. Here are a couple of examples:
As you can see (I hope), Doxygen/GraphViz seem to give up when the graph gets too large and gray out the child nodes. I then have to go to the graph for that specific node if I want to see what's further down the tree. Not only does this limit the visual helpfulness of the graph, but if the child node depends on any of the nodes from the original graph, these nodes will be shown again. This is leading to lots of duplicate connections that make it very hard to conceptually isolate the graph from any given file. As a result, I feel like I'm "zoomed in" and still can't see the whole picture.
I've tried playing around with the DOT_GRAPH_MAX_NODES setting in the Expert view in Doxygen, but this doesn't seem to affect the scope of the graphs that are being generated. From the output generated from any given run, it seems like Doxygen itself is generating hundreds of graph files, and Graphviz is just faithfully generating graphs for each one. Is there any known way to make Doxygen generate one large graph file instead of hundreds of smaller ones?
Alternatively, are there any free visual graphing solutions out there which know how to handle complicated C++ project files with nested pre-processor directives, MIDL interfaces, and manually defined include paths the way Doxygen does?
My searches are finding general graphing utilities (or questions about them), but nothing specific to large C++ projects. Surely with all the coding that's been done over the years somebody must have such a tool!
Thanks,

You can use the XML files generated by doxygen, and merge them into a single giant dot-format graph file (using xml stylesheet or similar), then run graphviz on it.
Doxygen automatically invoking graphviz is most useful when the number of graphs is high. For a single graph, automatically creating the content is important, but automatically calling dot, not so much.
With visual studios you can put your mouse over a variable which will pop up [classname] with members and node names. You can look through a tree of objects, see what values they hold, etc with it.
Is there a way i can dump it into a file so i can easily see it? I had to click >50 times to look through this object and its not a very complex object either..
I am using visual studios 2010 but i don't mind gcc if it has a tool for this task
You can use Doxygen to create a cross-referenced documentation of your code based on the annotations. It's quite simple, and will provide the info you're looking for and so much more.
Other than cross-referencing and type hierarchy, you will also be able to get calling graphs, references, and if you put the annotations in your code - documentation. Very powerful tool.
I was going to create the C++ IDE Vim extendable plugin. It is not a problem to make one which will satisfy my own needs.
This plugin was going to work with workspaces, projects and its dependencies.
This is for unix like system with gcc as c++ compiler.
So my question is what is the most important things you'd need from an IDE? Please take in account that this is Vim, where almost all, almost, is possible.
Several questions:
How often do you manage different workspaces with projects inside them and their relationships between them? What is the most annoying things in this process.
Is is necessary to recreate "project" from the Makefile?
Thanks.
Reason to create this plugin:
With a bunch of plugins and self written ones we can simulate most of things. It is ok when we work on a one big "infinitive" project.
Good when we already have a makefile or jam file. Bad when we have to create our owns, mostly by copy and paste existing.
All ctags and cscope related things have to know about list of a real project files. And we create such ones. This <project#get_list_of_files()> and many similar could be a good project api function to cooperate with an existing and the future plugins.
Cooperation with an existing makefiles can help to find out the list of the real project files and the executable name.
With plugin system inside the plugin there can be different project templates.
Above are some reasons why I will start the job. I'd like to hear your one.
There are multiple problems. Most of them are already solved by independent and generic plugins.
Regarding the definition of what is a project.
Given a set of files in a same directory, each file can be the unique file of a project -- I always have a tests/ directory where I host pet projects, or where I test the behaviour of the compiler. On the opposite, the files from a set of directories can be part of a same and very big project.
In the end, what really defines a project is a (leaf) "makefile" -- And why restrict ourselves to makefiles, what about scons, autotools, ant, (b)jam, aap? And BTW, Sun-Makefiles or GNU-Makefiles ?
Moreover, I don't see any point in having vim know the exact files in the current project. And even so, the well known project.vim plugin already does the job. Personally I use a local_vimrc plugin (I'm maintaining one, and I've seen two others on SF). With this plugin, I just have to drop a _vimrc_local.vim file in a directory, and what is defined in it (:mappings, :functions, variables, :commands, :settings, ...) will apply to each file under the directory -- I work on a big project having a dozen of subcomponents, each component live in its own directory, has its own makefile (not even named Makefile, nor with a name of the directory)
Regarding C++ code understanding
Every time we want to do something complex (refactorings like rename-function, rename-variable, generate-switch-from-current-variable-which-is-an-enum, ...), we need vim to have an understanding of C++. Most of the existing plugins rely on ctags. Unfortunately, ctags comprehension of C++ is quite limited -- I have already written a few advanced things, but I'm often stopped by the poor information provided by ctags. cscope is no better. Eventually, I think we will have to integrate an advanced tool like elsa/pork/ionk/deshydrata/....
NB: That's where, now, I concentrate most of my efforts.
Regarding Doxygen
I don't known how difficult it is to jump to the doxygen definition associated to a current token. The first difficulty is to understand what the cursor is on (I guess omnicppcomplete has already done a lot of work in this direction). The second difficulty will be to understand how doxygen generate the page name for each symbol from the code.
Opening vim at the right line of code from a doxygen page should be simple with a greasemonkey plugin.
Regarding the debugger
There is the pyclewn project for those that run vim under linux, and with gdb as debugger. Unfortunately, it does not support other debuggers like dbx.
Responses to other requirements:
When I run or debug my compiled program, I'd like the option of having a dialog pop up which asks me for the command line parameters. It should remember the last 20 or so parameters I used for the project. I do not want to have to edit the project properties for this.
My BuildToolsWrapper plugin has a g:BTW_run_parameters option (easily overridden with project/local_vimrc solutions). Adding a mapping to ask the arguments to use is really simple. (see :h inputdialog())
work with source control system
There already exist several plugins addressing this issue. This has nothing to do with C++, and it must not be addressed by a C++ suite.
debugger
source code navigation tools (now I am using http://www.vim.org/scripts/script.php?script_id=1638 plugin and ctags)
compile lib/project/one source file from ide
navigation by files in project
work with source control system
easy acces to file changes history
rename file/variable/method functions
easy access to c++ help
easy change project settings (Makefiles, jam, etc)
fast autocomplette for paths/variables/methods/parameters
smart identation for new scopes (also it will be good thing if developer will have posibility to setup identation rules)
highlighting incorrect by code convenstion identation (tabs instead spaces, spaces after ";", spaces near "(" or ")", etc)
reformating selected block by convenstion
Things I'd like in an IDE that the ones I use don't provide:
When I run or debug my compiled program, I'd like the option of having a dialog pop up which asks me for the command line parameters. It should remember the last 20 or so parameters I used for the project. I do not want to have to edit the project properties for this.
A "Tools" menu that is configurable on a per-project basis
Ability to rejig the keyboard mappings for every possible command.
Ability to produce lists of project configurations in text form
Intelligent floating (not docked) windows for debugger etc. that pop up only when I need them, stay on top and then disappear when no longer needed.
Built-in code metrics analysis so I get a list of the most complex functions in the project and can click on them to jump to the code
Built-in support for Doxygen or similar so I can click in a Doxygen document and go directly to code. Sjould also reverse navigate from code to Doxygen.
No doubt someone will now say Eclipse can do this or that, but it's too slow and bloated for me.
Adding to Neil's answer:
integration with gdb as in emacs. I know of clewn, but I don't like that I have to restart vim to restart the debugger. With clewn, vim is integrated into the debugger, but not the other way around.
Not sure if you are developing on Windows, but if you are I suggest you check out Viemu. It is a pretty good VIM extension for Visual Studio. I really like Visual Studio as an IDE (although I still think VC6 is hard to beat), so a Vim extension for VS was perfect for me. Features that I would prefer worked better in a Vim IDE are:
The Macro Recording is a bit error prone, especially with indentation. I find I can easily and often record macros in Vim while I am editing code (eg. taking an enum defn from a header and cranking out a corresponding switch statement), but found that Viemu is a bit flakey in that deptartment.
The VIM code completion picks up words in the current buffer where Viemu hooks into the VS code completion stuff. This means if I have just created a method name and I want to ctrl ] to auto complete, Vim will pick it up, but Viemu won't.
For me, it's just down to the necessities
nice integration with ctags, so you can do jump to definition
intelligent completion, that also give you the function prototype
easy way to switch between code and headers
interactive debugging with breaakpoints, but maybe
maybe folding
extra bonus points for refactoring tools like rename or extract method
I'd say stay away from defining projects - just treat the entire file branch as part of the "project" and let users have a settings file to override that default
99% of the difference in speed I see between IDE and vim users is code lookup and navigation. You need to be able to grep your source tree for a phrase (or intelligently look for the right symbol using ctags), show all the hits, and switch to that file in like two or three keystrokes.
All the other crap like repository navigation or interactive debugging is nice, but there are other ways to solve those problems. I'd say drop the interactive debugging even. Just focus on what makes IDEs good editors - have a "big picture" view of your project, instead of single file.
In fact, are there any plugins for vim that already achieve this?
