// Various clangd features have configurable behaviour (or can be disabled).
|
|
// This file defines "resolved" configuration seen by features within clangd.
|
|
// For example, settings may vary per-file, the resolved Config only contains
|
|
// settings that apply to the current file.
|
|
//
|
|
// This is distinct from how the config is specified by the user (Fragment)
|
|
// interpreted (CompiledFragment), and combined (Provider).
|
|
// ConfigFragment.h describes the steps to add a new configuration option.
|
|
//
|
|
// Because this structure is shared throughout clangd, it's a potential source
|
|
// of layering problems. Config should be expressed in terms of simple
|
|
// vocubulary types where possible.
