Fix#180
index.initialBlacklist: ["."] can inhibit initial indexing (useful for larger code bases).
Opened files are still indexed, though.
This heuristic allows related files (a/foo.c a/b/foo.cc) to be indexed when a header (foo.h) is opened.
* In the "initialized" callback, send client/registerCapability with DidChangeWatchedFilesRegistrationOptions
* In workspace/didChangeWatchedFiles callback, call pipeline::Index
* In pipeline::Index, add a `deleted` status
* Add %h for C header files (the suffix .h is considered a C header, not a C++ header)
* Add %hpp for C++ header files
* If .ccls exists, it provides full command line for files not specified by compile_commands.json (before, compile_commands.json was ignored)
* If the first line of .ccls is %compile_commands.json, it appends flags to compile_commands.json "arguments", instead of overriding.
Files not specified by compile_commands.json will not be added to folder.entries, but their command line can be inferred from other files.
Also fix `#include <` completion of -I flags for clang < 8
* WorkingFiles::files : vector -> unordered_map
* Add timestamp to WorkingFile
* Rename "comp-preload" thread to "preamble"
* Rename CompletionManager to SemaManager as it is used by "diag" "comp" "preamble"
* Rename clang_complete.* to sema_manager.*
* Merge SemaManager::{preloads,sessions}
* Add initialization option session.maxNum
* In DiagnosticMain, if an included file was modified, cancel the DiagTask and create a PreambleTask instead. The task sets `from_diag` so as to trigger immediate DiagTask after the preamble is built.
* Better LanguageId detection with clangDriver (e.g. .cu -> types::TY_CUDA)
* fallback when there is no .ccls or compile_commands.json
Also Hide clangTooling options from --help
index.{blacklist,whitelist}: disable indexes thoroughly
index.initial{Blacklist,Whitelist}: disable initial loading. will still be indexed after opening
Move using below #include to make preamble happy
textDocument/references: if no references, first line or last line => list where this file is included
malloc_trim() only if files have been indexed in last cycle
Intern: use CachedHashStringRef
1. Normalize paths in LSP document URIs and project root to forward
slash and uppercase drive letters.
2. Normalize paths in compile_commands.json to forward slash and
uppercase drive letters.
3. Normalize paths from directory listing to forward slash. (Drive
letter should be same as input dir path, which is already uppercase
since path of project root dir is normalized)
4. Add llvm::sys::path::convert_to_slash after certain llvm::sys::path
and llvm::fs calls.
