Functions ¶
func Clone ¶ added in v0.0.508
func Clone[T any](v T) T
Clone clones *public fields* in a structure. Private fields may or may not be copied, and private pointers may or may not point into the original object.
- this will panic if the structure is not serializable
- See CloneFallible
func CloneFallible ¶ added in v0.0.508
CloneFallible clones *public fields* in a structure. Private fields may or may not be copied, and private pointers may or may not point into the original object.
- returns an error if the structure is not serializable
- See Clone
func DirectoryExists ¶
func FileExists ¶
func GetConfigDirectory ¶ added in v0.1.123
GetConfigDirectory will return where config and state files should be stored, either respecting `FLY_CONFIG_DIR` or defaulting to the user's home directory at `~/.fly`.
func IsTerminal ¶ added in v0.0.183
func IsTerminal() bool
func MakeSimpleTable ¶ added in v0.0.145
func MakeSimpleTable(out io.Writer, headings []string) (table *tablewriter.Table)
func PathRelativeToCWD ¶
func RandBytes ¶ added in v0.0.348
RandBytes generates random bytes of a given length See: https://stackoverflow.com/questions/35781197/generating-a-random-fixed-length-byte-array-in-go
func RandString ¶ added in v0.0.261
RandString returns a string of n bytes, consisting of ASCII letters or numbers.
func WriteFileAtomically ¶ added in v0.4.112
WriteFileAtomically writes data to a temporary file beside path, flushes it to disk, and renames it over path. A write that fails part way, for example on a full disk, leaves whatever was at path untouched. The rename also means a reader that already had the old file open never sees the new contents, so a file carrying a credential can safely be rewritten over a more permissive one. os.WriteFile truncates first and writes second, which both leaves an empty file behind on failure (an empty config reads back as a logged-out flyctl) and exposes the new contents through any open handle at the old mode.
