func FirstError ¶

func FirstError(pkgs []goutil.Packages, errs []error) ([]goutil.Packages, error)

FirstError is meant to wrap Import, it returns pkgs unchanged. If there were errors, only the first is returned.

func Flatten ¶

func Flatten(pss []goutil.Packages) (out goutil.Packages)

Flatten takes a slice of goutil.Packages and returns a single goutil.Packages containing only the unique packages from the slice.

func Import ¶

func Import(notree bool, ctx *build.Context, args []string) (pkgs []goutil.Packages, errs []error)

Import is for importing command line arguments. It uses the following rules:

If args is len 0, try to import the current directory.
Otherwise, for each argument:
	If it ends with ..., use goutil.ImportTree (unless notree is true)
	Otherwise, use goutil.Import

Regardless, the ctx is passed as is to the various importers.

Import returns a list of any errors that resulted from attmepting to import. If you only care about the first error, wrap the call in FirstError.

func ImportOne ¶

func ImportOne(notree bool, ctx *build.Context, args []string) (goutil.Packages, error)

ImportOne only allows one argument to be specified.

func TagsFlag ¶

func TagsFlag(tags string) *[]string

TagsFlag defines a tags flag, matching the tags flag on the go tool. The returned value is the address of a []string variable that stores the value of that flag.

The tags flag behaves exactly like the -tag flag for the go tool.

The name of the flag is always tags. The usage string is set to one similar to the usage of the tags flag on the go tool.

func TagsFlagSet ¶

func TagsFlagSet(f *flag.FlagSet, tags string) *[]string

TagsFlagSet defines a tags flag, matching the tags flag on the go tool. The returned value is the address of a []string variable that stores the value of that flag.

The tags flag behaves exactly like the -tag flag for the go tool.

The name of the flag is always tags. The usage string is set to one similar to the usage of the tags flag on the go tool.

func TagsFlagSetVar ¶

func TagsFlagSetVar(f *flag.FlagSet, val *[]string, tags string)

TagsFlagSetVar defines a tags flag, matching the tags flag on the go tool.

The tags flag behaves exactly like the -tag flag for the go tool.

The name of the flag is always tags. The usage string is set to one similar to the usage of the tags flag on the go tool.

func TagsFlagVar ¶

func TagsFlagVar(val *[]string, tags string)

TagsFlagVar defines a tags flag, matching the tags flag on the go tool.

The tags flag behaves exactly like the -tag flag for the go tool.

The name of the flag is always tags. The usage string is set to one similar to the usage of the tags flag on the go tool.
