Detailed Description

StoreDiags collects the diagnostics that can later be reported by clangd.

It groups all notes for a diagnostic into a single Diag and filters out diagnostics that don't mention the main file (i.e. neither the diag itself nor its notes are in the main file).

DiagCallback

using clang::clangd::StoreDiags::DiagCallback

Initial value:

 
      std::function<void(const clang::Diagnostic &, clangd::Diag &)>

Definition at line 151 of file Diagnostics.h.

DiagFinalizer

using clang::clangd::StoreDiags::DiagFinalizer = std::function<void(Diag &)>

Definition at line 153 of file Diagnostics.h.

DiagFixer

using clang::clangd::StoreDiags::DiagFixer

Initial value:

 std::function<std::vector<Fix>(DiagnosticsEngine::Level,
                                                   const clang::Diagnostic &)>

When passed a main diagnostic, returns fixes to add to it.

When passed a note diagnostic, returns fixes to replace it with.
