The gotype command does syntactic and semantic analysis of Go files and packages like the front-end of a Go compiler. Errors are reported if the analysis fails; otherwise gotype is quiet (unless -v is set).
Without a list of paths, gotype reads from standard input, which must provide a single Go source file defining a complete package.
If a single path is specified that is a directory, gotype checks the Go files in that directory; they must all belong to the same package.
Otherwise, each path must be the filename of Go file belonging to the same package.
gotype [flags] [path...]
The flags are:
-a use all (incl. _test.go) files when processing a directory -e report all errors (not just the first 10) -v verbose mode -gccgo use gccimporter instead of gcimporter
-seq parse sequentially, rather than in parallel -ast print AST (forces -seq) -trace print parse trace (forces -seq) -comments parse comments (ignored unless -ast or -trace is provided)
To check the files a.go, b.go, and c.go:
gotype a.go b.go c.go
To check an entire package in the directory dir and print the processed files:
gotype -v dir
To check an entire package including tests in the local directory:
gotype -a .
To verify the output of a pipe:
echo "package foo" | gotype
