gotype1

Usage

Overview

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.

Options

-a

use all (incl. _test.go) files when processing a directory

-ast

print AST (forces -seq)

-comments

parse comments (ignored unless -ast or -trace is provided)

-e

report all errors (not just the first 10)

-seq

parse sequentially, rather than in parallel

-trace

print parse trace (forces -seq)

-v

verbose mode

Examples

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
