## Project history and usage

hotbuild is a small Go development utility for automatically rebuilding and rerunning a project when files change. Its upstream site and README present it as a cross-platform hot compilation tool for Go projects.

### Project history

The project is published by Wander/rustpub under the wandercn GitHub account, with the documentation site carrying rustpub branding and a 2021 copyright. The README examples show the tool creating a project-local `.hotbuild.toml` file and running a Go build command into a temporary binary before launching it.

### Adoption history

hotbuild has a narrow package footprint compared with larger Go live-reload tools, but Homebrew packages it as `hotbuild` and builds from the upstream GitHub release archive. That makes it discoverable to macOS and Linux developers who install small Go CLIs through Homebrew.

### How it is used

The documented workflow is to run `hotbuild initconf` inside a Go project, edit the generated build and run commands, then use `hotbuild run` while developing. The tool watches recursive subdirectories under the configured project path and can separate the watched directory from the command working directory.

### Why package nerds care

For package-manager people, hotbuild is an example of the file-watcher hot-reload pattern packaged as a tiny standalone Go command. It is less important as an ecosystem standard than as a representative of many small development-loop accelerators that package managers preserve.

### Timeline

- 2021: The project site and README examples document hotbuild as a Go hot-compilation tool with `.hotbuild.toml` project configuration.
- v1.0.5: README run output shows the tool banner and rebuild/run loop around a Go application.
- v1.0.9: Homebrew builds the formula from the upstream GitHub release archive.

### Related projects

- Go's own `go build` remains the underlying compilation command in the documented examples.
- Other Go development-loop tools such as air, reflex, and fresh occupy the same file-watch-and-rerun niche, though hotbuild keeps its own simple configuration format.
