Re: [cdt-dev] How to open a file at a particular function
|
Here's some code that shows how I did it, in case anybody is interested:
public void findFunctionInSource(IProject project, String functionName) {
ICProject cProject = CoreModel.getDefault().getCModel().getCProject(
project.getName());
IIndexManager manager = CCorePlugin.getIndexManager();
try {
index = manager.getIndex(cProject);
index.acquireReadLock();
IBinding[] bindings = index.findBindings(
functionName.toCharArray(), IndexFilter.ALL,
new NullProgressMonitor());
for (int binding = 0; binding < bindings.length; binding++) {
if (bindings[binding] instanceof IFunction) {
IFunction ifunction = (IFunction) bindings[binding];
IIndexName[] names = index.findNames(ifunction,
IIndex.FIND_DEFINITIONS);
for (int j = 0; j < names.length; j++) {
IIndexFile file = names[j].getFile();
if (file != null) {
IIndexFileLocation filelocation = file
.getLocation();
String fileName = filelocation.getFullPath();
}
IASTFileLocation location = names[j].getFileLocation();
if (location != null) {
int .offset = location.getNodeOffset();
}
}
}
}
} catch (Exception e) {
} finally {
if (index != null)
index.releaseReadLock();
}
}

Phew - I'm there.
Whilst there are docs for the API, there doesn't seem to be anything that
describes *how* to use them. Maybe it is documented in this series of
emails?
I think you just did ;)
Documenting something like this is definitely on my wish list for API docs.
Not just javadoc, but howto's too.
Anyway, thanks very much for your help - it is very much appreciated.

Markus,
Almost there now...
I now get a list of all my functions in an IIndexName[]. I
can get the files
they are defined in through IIndexName#getFile(). However,
IIndexName#getFileLocation().getStartingLineNumber() always
returns zero. The
javaDoc (for IASTFileLocation) states "Locations obtained via
the index do not
have line numbers and return 0".
So, (hopefully) one last question: how do obtain the line number?
Thanks very much for you help so far.

An IBinding does not have a location, you need to obtain a name

IIndex.findName(IBinding ...) or similar.

Markus,
OK, I now have an IBinding to my function, but again it's not
obvious how to
turn this into a source file/line number (or a direct way to
open the source
file at the line number). I've tried ILinkage, IScope, ...
Thanks again.

Markus,
I've just come to implement this - thanks for the pointer.
One question - how do I convert an IProject (which I have
readily available at
debug time) into its corresponding ICProject?
Thanks

You should use the interface
org.eclipse.cdt.core.index.IIndex. It's
experimental API but most likely it will only be extended,
not changed.
The interfaces for accessing the index are well documented.
Many of the
testcases in CDT illustrate how to use them,
e.g.: org.eclipse.cdt.internal.index.tests.IndexBugsTests

Hi,
Given a function or method name (as a String), how can I
locate the file it is
defined in and open that file at the function definition? Any
pointers to code,
snippets or docs would be very useful.
Thanks
