Functions

func AsString added in v0.10.18

func AsString(x starlark.Value) (string, bool)

Wrapper around starlark.AsString

func SequenceToStringSlice added in v0.10.15

func SequenceToStringSlice(seq starlark.Sequence) ([]string, error)

func StringSliceToList added in v0.10.22

func StringSliceToList(slice []string) *starlark.List

func ValueGroupToCmdHelper added in v0.14.0

func ValueGroupToCmdHelper(cmdVal, cmdBatVal starlark.Value) (model.Cmd, error)

In other similar build systems (Buck and Bazel), there's a "main" command, and then various per-platform overrides. https://docs.bazel.build/versions/master/be/general.html#genrule.cmd_bat This helper function abstracts out the precedence rules.

func ValueOrSequenceToSlice

func ValueOrSequenceToSlice(v starlark.Value) []starlark.Value

If `v` is a `starlark.Sequence`, return a slice of its elements Otherwise, return it as a single-element slice For functions that take `Union[List[T], T]`

func ValueToAbsPath added in v0.10.15

func ValueToAbsPath(thread *starlark.Thread, v starlark.Value) (string, error)

func ValueToBatCmd added in v0.14.0

func ValueToBatCmd(v starlark.Value) (model.Cmd, error)

func ValueToHostCmd added in v0.14.0

func ValueToHostCmd(v starlark.Value) (model.Cmd, error)

provides dockerfile-style behavior of: a string gets interpreted as a shell command (like, sh -c 'foo bar $X') an array of strings gets interpreted as a raw argv to exec

func ValueToUnixCmd added in v0.14.0

func ValueToUnixCmd(v starlark.Value) (model.Cmd, error)
