README 

This directory does not contain a Go package,
but acts as a container for various analyses
that implement the golang.org/x/tools/go/analysis
API and may be imported into an analysis tool.

By convention, each package foo provides the analysis,
and each command foo/cmd/foo provides a standalone driver.

fieldalignment/cmd/fieldalignment
findcall Package findcall defines an Analyzer that serves as a trivial example and test of the Analysis API.

httpresponse Package httpresponse defines an Analyzer that checks for mistakes using HTTP responses.
ifaceassert Package ifaceassert defines an Analyzer that flags impossible interface-interface type assertions.
ifaceassert/cmd/ifaceassert The ifaceassert command runs the ifaceassert analyzer.
inspect Package inspect defines an Analyzer that provides an AST inspector (golang.org/x/tools/go/ast/inspect.Inspect) for the syntax trees of a package.

shift Package shift defines an Analyzer that checks for shifts that exceed the width of an integer.
sortslice Package sortslice defines an Analyzer that checks for calls to sort.Slice that do not use a slice type as first argument.
stdmethods Package stdmethods defines an Analyzer that checks for misspellings in the signatures of methods similar to well-known interfaces.
stringintconv Package stringintconv defines an Analyzer that flags type conversions from integers to strings.
stringintconv/cmd/stringintconv The stringintconv command runs the stringintconv analyzer.
structtag Package structtag defines an Analyzer that checks struct field tags are well formed.
testinggoroutine
tests Package tests defines an Analyzer that checks for common mistaken usages of tests and examples.
unmarshal The unmarshal package defines an Analyzer that checks for passing non-pointer or non-interface types to unmarshal and decode functions.
