I think we should change how we structure our files.
IMO, we should have SourceArguments, SourceResponse and SourceRequestHandler all in Handlers/SourceRequestHandler.{h,cpp}. That way, we have all the SourceRequest-related things in one place.
Not sure where Source should go. If it's only used by the SourceRequestHandler, I would also put it into Handlers/SourceRequestHandler.{h,cpp}, otherwise we might move it to ProtocolTypes.{h,cpp} or even ProtocolTypes/Source.{h,cpp}

otherwise we might move it to ProtocolTypes.{h,cpp} or even ProtocolTypes/Source.{h,cpp}
and maybe move the existing Protocol.{h,cpp} to BaseProtocol.{h,cpp}? To keep the base protocol separated from the other request / response / event types?

I personally like the protocol being isolated into its own namespace and its own file.
There are actually a few examples of this already in llvm, e.g. clang-tools-extra/clangd/Protocol.h or mlir/include/mlir/Tools/lsp-server-support/Protocol.h.
This is nice because we can easily look in the file for other types defined in the protocol and add new types as we need them. For example, you mentioned the Source type, which is used in a few events and requests.
The DAP spec already groups at a high level into Base Protocol, Events, Requests, Reverse Requests and Types, which I was roughly following in this file using // MARK: <category> headings between sections.
I only left the description of the SourceRequest next to the handler for reference for the implementation.
I'm fine with changing how we structure things, but I liked having the distinction between lldb_dap::protocol for the underlying protocol, lldb_dap for our intermediate components and lldb/lldb_private for the SB API layer of the debugger itself.

Indeed, you brought up a couple of good arguments for keeping the protocol separate. I am undecided. Let's see if anyone else jumps in and also has additional arguments in either direction. Otherwise, I would be fine with either way.
The DAP spec already groups at a high level into Base Protocol, Events, Requests, Reverse Requests and Types, which I was roughly following in this file using // MARK: headings between sections.
Even if we don't move *Args, *Request and *Response types to the corresponding *RequestHandler, I think we should still separate the base protocol from the remaining protocol types. I would prefer separate files over // MARK: <category> comments for that purpose, i.e. a Protocol.{h,cpp} (containing the events, request and response types) and a separate BaseProtocol.{h,cpp} (containing the base protocol)

@JDevlieghere Any thoughts on the organization of these types?
I was keeping things simple by putting the types in a single place, but we don't strictly need to do that.
We could have ProtocolBase.h, ProtocolTypes.h, ProtocolRequests.h, ProtocolEvents.h, etc.

I can see an argument for either. If it were up to me, I'd go with the different Protocol* files in a Protocol subdirectory. My (entirely subjective) reasoning is that the protocol should match the spec, rather than how it's used in our implementation and therefore it warrants standing on its own. Things were different when we didn't have the abstraction and type safety offered by the Protocol class and we had to consult the spec to decode a message, but now that's not a concern anymore if you're using an IDE or editor with code completion.

Split up the Protocol.{h,cpp} > Protocol/Protocol{Base,Requests,Types}.{h,cpp}.
…ponse. This is a work in progress refactor to add explicit types instead of generic 'llvm::json::Value' types to the DAP protocol. This updates RequestHandler to have take the type of the arguments and response body for serialization for requests. The 'source' request is updated to show how the new flow works.
…stead extracting the comments to their c++ repr.

What is your overall plan for this PR? I assume the first step is to get buy-in from all reviewers into the new structure for our JSON types. But what comes after? Are you planning to update this PR to cover all JSON types / requests / responses? Are you planning to land this PR for the (Both approaches would be fine by me. Just trying to understand the approach, so I know when it's time to hit the "Approve" button 😉) |

…ssages without a response body. To validate both of these changes I also migrated the 'disconnect' request to have new types, since it has an `optional<DisconnectArguments>` and a `VoidResponse` body.
I was thinking of doing this more incrementally. I was planning to build on this for handling the 'cancel' request first but then I'd like to follow up with requests to use the new explicit types for handling arguments and responses. |
…`DAP::Disconnect` method a little more ergnomic.

✅ With the latest revision this PR passed the C/C++ code formatter. |
…refix. The types should be enough to tell that theyre not specific values and this helps with the naming consistency.
This is a work in progress refactor to add explicit types instead of
generic 'llvm::json::Value' types to the DAP protocol.
This updates RequestHandler to have take the type of the arguments and
response body for serialization for requests.
The 'source' and 'disconnect' request is updated to show how the new flow
works and includes serialization handling for optional arguments and 'void'
responses.
This is built on top of #130026
