# cquery
|
|
|
|
cquery is a highly-scalable, low-latency language server for C/C++/Objective-C. It is tested
|
|
and designed for large code bases like
|
|
[Chromium](https://chromium.googlesource.com/chromium/src/). cquery provides
|
|
accurate and fast semantic analysis without interrupting workflow.
|
|
|
|
|
|
|
|
cquery implements almost the entire language server protocol and provides
|
|
some extra features to boot:
|
|
|
|
* code completion (with both signature help and snippets)
|
|
* finding definition/references
|
|
* call (caller/callee) hierarchy, inheritance (base/derived) hierarchy, member hierarchy
|
|
* symbol rename
|
|
* [document symbols](src/messages/text_document_document_symbol.cc) and approximate search of [workspace symbol](src/messages/workspace_symbol.cc)
|
|
* [hover information](src/messages/text_document_hover.cc)
|
|
* diagnostics
|
|
* code actions (clang FixIts)
|
|
* preprocessor skipped regions
|
|
* #include auto-complete, undefined type include insertion, include quick-jump
|
|
(goto definition, document links)
|
|
* auto-implement functions without a definition
|
|
* semantic highlighting, including support for [rainbow semantic highlighting](https://medium.com/@evnbr/coding-in-color-3a6db2743a1e)

# Limitations
|
|
|
|
cquery is able to respond to queries quickly because it caches a huge amount of
|
|
information. When a request comes in, cquery just looks it up in the cache
|
|
without running many computations. As a result, there's a large memory overhead.
|
|
For example, a full index of Chrome will take about 10gb of memory. If you
|
|
exclude v8, webkit, and third_party, it goes down to about 6.5gb.
