## godef - find symbol information in Go source

Godef, given an expression or a location in a source file, prints the
location of the definition of the symbol referred to.

Known limitations:

- it does not understand about "." imports
- it does not like imports where the last element import path doesn't match
the package identifier.

Documentation

Overview

Godef prints the source location of definitions in Go programs.

Usage:

godef [-t] [-a] [-A] [-o offset] [-i] [-f file][-acme] [expr]

File specifies the source file in which to evaluate expr. Expr must be an identifier or a Go expression terminated with a field selector.

If expr is not given, then offset specifies a location within file, which should be within, or adjacent to an identifier or field selector.

If the -t flag is given, the type of the expression will also be printed. The -a flag causes all the public members (fields and methods) of the expression, and their location, to be printed also; the -A flag prints private members too.

If the -i flag is specified, the source is read from standard input, although file must still be specified so that other files in the same source package may be found.

If the -acme flag is given, the offset, file name and contents are read from the current acme window.

Example:

$ cd $GOROOT
$ godef -f src/pkg/xml/read.go 'NewParser().Skip'
src/pkg/xml/read.go:384:18
$
