It is a package-nerd tool for people optimizing slow native builds rather than a general application framework. ### Project history The repository was created in August 2019 after Clang 9 introduced -ftime-trace. The README says the tool takes the single-file trace output generated by Clang and aggregates many compilation traces into summaries of slow files, templates, functions, code generation, and expensive headers. ### Adoption history The supplied package-manager data lists Homebrew and Nix packaging. Release metadata shows an initial 1.0.0 release labeled 'Initial release' and later releases tracking newer Clang support, including Clang 19 support in 1.6.0. ### How it is used A typical workflow starts capture with ClangBuildAnalyzer --start, builds with Clang 9 or later using -ftime-trace, stops capture with --stop, and runs --analyze on the produced capture file. A ClangBuildAnalyzer.ini file in the working directory controls how many expensive files, templates, functions, and headers are reported. ### Why package nerds care It matters because it packages a practical workflow around a compiler diagnostic format. For large C++ codebases, it turns a pile of per-object JSON traces into actionable package-maintainer and build-engineer questions: which headers, templates, source files, or compiler phases are costing rebuild time? ### Timeline - 2019: Repository created after Clang 9 documented -ftime-trace. - 2020: v1.0.0 initial release published on GitHub. - 2020: v1.2.0 focused on optimizations for large builds. - 2023: v1.5.0 improved expensive-header information. - 2025: v1.6.0 added Clang 19 support and fixes. ### Related projects - Related projects include Clang, LLVM, Clang's -ftime-trace support, Chrome trace viewers, speedscope.app, and native build systems such as Make, CMake, Xcode, and Visual Studio. ### Sources - - - - - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials.
