* [clangd] Move clangd tests to clangd directory. check-clangd is no longer ↵Sam McCall2019-04-291-68/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | part of check-clang-tools. Summary: Motivation: - this layout is a pain to work with - without a common root, it's painful to express things like "disable clangd" (D61122) - CMake/lit configs are a maintenance hazard, and the more the one-off hacks for various tools are entangled, the more we see apathy and non-ownership. This attempts to use the bare-minimum configuration needed (while still supporting the difficult cases: windows, standalone clang build, dynamic libs). In particular the lit.cfg.py and lit.site.cfg.py.in are merged into lit.cfg.in. The logic in these files is now minimal. (Much of clang-tools-extra's lit configs can probably be cleaned up by reusing lit.llvm.llvm_config.use_clang(), and every llvm project does its own version of LDPATH mangling. I haven't attempted to fix any of those). Docs are still in clang-tools-extra/docs, I don't have any plans to touch those.

* [clangd] Use shorter, more recognizable codes for diagnostics.Sam McCall2019-04-171-1/+1
| | | | | | | | | | | | | | | | | | | | | Summary: - for warnings, use the flag the warning is controlled by (-Wfoo) - for errors, keep using the internal name (there's nothing better) but drop the err_ prefix This comes at the cost of uniformity, it's no longer totally obvious exactly what the code field contains. But the -Wname flags are so much more useful to end-users than the internal warn_foo that this seems worth it.

* [clangd] Refactor JSON-over-stdin/stdout code into Transport abstraction. ↵Sam McCall2018-10-171-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | (re-land r344620) Summary: This paves the way for alternative transports (mac XPC, maybe messagepack?), and also generally improves layering: testing ClangdLSPServer becomes less of a pipe dream, we split up the JSONOutput monolith, etc. This isn't a final state, much of what remains in JSONRPCDispatcher can go away, handlers can call reply() on the transport directly, JSONOutput can be renamed to StreamLogger and removed, etc. But this patch is sprawling already. The main observable change (see tests) is that hitting EOF on input is now an error: the client should send the 'exit' notification. This is defensible: the protocol doesn't spell this case out. Reproducing the current behavior for all combinations of shutdown/exit/EOF clutters interfaces. We can iterate on this if desired.

* [clangd] Emit ranges for clangd diagnostics, and fix off-by-one positionsSam McCall2017-12-131-4/+4
| | | | | | | | | | | | | | | | | | | Summary: - when the diagnostic has an explicit range, we prefer that - if the diagnostic has a fixit, its RemoveRange is our next choice - otherwise we try to expand the diagnostic location into a whole token. (inspired by VSCode, which does this client-side when given an empty range) - if all else fails, we return the zero-width range as now. (clients react in different ways to this, highlighting a token or a char) - this includes the off-by-one fix from D40860, and borrows heavily from it Reviewers: rwols, hokein Subscribers: klimek, ilya-biryukov, cfe-commits Differential Revision: https://reviews.llvm.org/D41118 llvm-svn: 320555
* Adds a json::Expr type to represent intermediate JSON expressions.Sam McCall2017-11-061-4/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This form can be created with a nice clang-format-friendly literal syntax, and gets escaping right. It knows how to call unparse() on our Protocol types. All the places where we pass around JSON internally now use this type. Object properties are sorted (stored as std::map) and so serialization is canonicalized, with optional prettyprinting (triggered by a -pretty flag). This makes the lit tests much nicer to read and somewhat nicer to debug. (Unfortunately the completion tests use CHECK-DAG, which only has line-granularity, so pretty-printing is disabled there. In future we could make completion ordering deterministic, or switch to unittests). Compared to the current approach, it has some efficiencies like avoiding copies of string literals used as object keys, but is probably slower overall. I think the code/test quality benefits are worth it. This patch doesn't attempt to do anything about JSON *parsing*. It takes direction from the proposal in this doc[1], but is limited in scope and visibility, for now. I am of half a mind just to use Expr as the target of a parser, and maybe do a little string deduplication, but not bother with clever memory allocation. That would be simple, and fast enough for clangd... [1] https://docs.google.com/document/d/1OEF9IauWwNuSigZzvvbjc1cVS1uGHRyGTXaoy3DjqM4/edit +cc d0k so he can tell me not to use std::map.

* [clangd] Handle clangd.applyFix server-sideMarc-Andre Laperle2017-11-031-0/+67
Summary: When the user selects a fix-it (or any code action with commands), it is possible to let the client forward the selected command to the server. When the clangd.applyFix command is handled on the server, it can send a workspace/applyEdit request to the client. This has the advantage that the client doesn't explicitly have to know how to handle clangd.applyFix. Therefore, the code to handle clangd.applyFix in the VS Code extension (and any other Clangd client) is not required anymore.
