README

        # Archived

cquery is no longer under development. [clangd](https://clangd.llvm.org/installation.html) and [ccls](https://github.com/MaskRay/ccls) are both good replacements.

# cquery

[![Join the chat at https://gitter.im/cquery-project/Lobby](https://badges.gitter.im/Join%20Chat.svg)](https://gitter.im/cquery-project/Lobby?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge)

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.

![Demo](https://ptpb.pw/GlSQ.png?raw=true)

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](src/messages/text_document_definition.cc)/[references](src/messages/text_document_references.cc)

  * [call (caller/callee) hierarchy](src/messages/cquery_call_hierarchy.cc), [inheritance (base/derived) hierarchy](src/messages/cquery_inheritance_hierarchy.cc)

  * [symbol rename](src/messages/text_document_rename.cc)

  * [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.
