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), [member hierarchy](src/messages/cquery_member_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) # >>> [Getting started](https://github.com/jacobdufault/cquery/wiki/Getting-started) (CLICK HERE) <<< Packaging status # 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. # License MIT
