Package checker is a driver for the analysis API.
It is an internal package, but is exposed by three different APIs:
analysistest, singlechecker, and multichecker.
Checker uses go/packages to load the specified packages (plus their
dependencies, if any analysis uses facts) from source code.
It constructs a graph of actions (analysis passes), whose dependency
edges may be "horizontal", when one analyzer depends on the output of
another applied to the same package, or "vertical", when an an
analyzer consumes facts produced by the same analyzer applied to a
dependency package.
The graph is executed in parallel, unless -debug=p.
Facts are passed from one pass to another in memory.
If -debug=s, facts are serialized, to exercise that logic.
Findings are printed at the end.
The -json flag selects JSON output.
Use -debug=t to print timing information.
Always use -debug=tp, for sequential mode, when timing.
Also:
- analysistest: a wrapper for testing checkers
- multichecker: a wrapper for writing multi-checker tools
Analysis flags are prefixed by name: -findcall.name=foo.
- cmd/analyze: a command-line tool based on multichecker
- singlechecker: a wrapper for writing single-checker tools
Analysis flags are unprefixed: -name=foo.
- passes/findcall/cmd/findcall: a standalone tool for the findcall analysis
- tests for findcall
- tests for pkgfact

Go Tools
This subrepository holds the source for various packages and tools that support the Go programming language.
Some of the tools, godoc and vet for example, are included in binary Go
distributions.
Others, including the Go guru and the test coverage tool, can be fetched with
go get.
Packages include a type-checker for Go and an implementation of the Static Single Assignment form (SSA) representation for Go programs.
Download/Install
The easiest way to install is to run go get -u golang.org/x/tools/.... You can
also manually git clone the repository to $GOPATH/src/golang.org/x/tools.
