func CreateTestMemMapFs ¶ added in v0.161.0

func CreateTestMemMapFs(t *testing.T, files map[string]string) afero.Fs

CreateTestMemMapFs creates a memory fs from provided files. Keys are used as given (a bare relative key like "a.arrai" ends up rooted at "/a.arrai", same as an already-absolute "/a.arrai" would) — see NewTestMemMapFs.

func FileExists ¶ added in v0.161.0

func FileExists(ctx context.Context, key interface{}, filePath string) (bool, error)

FileExists checks if the provided file exists in the zip filesystem.

func NewTestMemMapFs ¶ added in v0.340.0

func NewTestMemMapFs() afero.Fs

NewTestMemMapFs returns a fresh afero.MemMapFs made safe to address with either a bare relative path or a native absolute path (as filepath.Abs produces, including on Windows). Use this instead of afero.NewMemMapFs() for any test fixture that will be read through arrai's normal (non-bundling) file-resolution code.

func OutputZip ¶ added in v0.161.0

func OutputZip(ctx context.Context, key interface{}, w io.Writer) error

OutputZip outputs a zip file from all the files in the filesystem to the provided writer.

func RuntimeFsFrom ¶

func RuntimeFsFrom(ctx context.Context) afero.Fs

RuntimeFsFrom extracts the filesystem used to access the filesystem from ctx. It will be used by //os.file and similar functions. TODO: Actually use it.

func RuntimeFsOnto ¶

func RuntimeFsOnto(ctx context.Context, runtimeFs afero.Fs) context.Context

RuntimeFsOnto returns a new Context with runtimeFs added to ctx.

func SetDefaultFs ¶

func SetDefaultFs(fs afero.Fs)

Sets the default Fs to be returned from SourceFsFrom and RuntimeFsFrom.

func SourceFsFrom ¶

func SourceFsFrom(ctx context.Context) afero.Fs

SourceFsFrom extracts the filesystem used for import resolution from ctx.

func SourceFsOnto ¶

func SourceFsOnto(ctx context.Context, sourceFs afero.Fs) context.Context

SourceFsOnto returns a new Context with sourceFs added to ctx.

func ToUnixPath ¶ added in v0.186.0

func ToUnixPath(p string) string

func WithZipFs ¶ added in v0.161.0

func WithZipFs(ctx context.Context, key interface{}) context.Context

WithZipFs adds a filesystem that can be used to output a zip file.

func ZipCreate ¶ added in v0.161.0

func ZipCreate(ctx context.Context, key interface{}, filePath string, content []byte) error

ZipCreate creates a file with the provided filepath and content. The filepath has to be in UNIX path format.

func ZipEqualToFiles ¶ added in v0.161.0

func ZipEqualToFiles(t *testing.T, buf []byte, files map[string]string)

ZipEqualToFiles is a test utility that compares a zip buffer to a map of files, whose keys are filepaths and values are content of the files.
