lsifdotnet's Issues

Feature request : option to exclude project/class/namespace

Hi again. I'm running into new issue. The generation of lsif file is ok now but I hit a size limit with gitlab. I know it's a setting but it will not be changed.

So I'm wondering if it could be possible to exclude some file/class/project/assembly to better control what is exported, and in a way, the size of the exported file to be under the threshold.

If you need idea, I like the way it's handle in ReportGenerator

Have a nice day :)

Feature request Add an option to merge 2 lsif file or happend to an existing one

I try to test the gitlab code intelligence feature. But have trouble to make it work with more than one lsif file.

I tried to just concat both into a new one, but I think it will not work both file use overlapping ids. (For context the other one come from docker image sourcegraph/lsif-node for react project)

Maybe I could use jq to re-index all id. But seem a little bit brutal.

Directory path instead of file path

Hello, It's me again. In the latest commit you introduce the method ToAbsoluteUri.

Is it on purpose to trim the file name and only keep the directory? From what I read the vertex uri should target the file instead of the directory.

Vertices being referenced before having been emitted

From the spec:

a vertex needs to be emitted before it can be referenced in an edge.

We discovered lsif-dotnet violates this constraint in its output, which caused LSIF files to be rejected by Sourcegraph

Screenshot of rejection from Sourcegraph:

Extract from the malformed LSIF file:
