Functions ¶
func PrettyByteSize ¶
PrettyByteSize formats a byte size (int) into a human-readable colored string using binary prefixes (KiB, MiB, etc.).
func UseColour ¶ added in v0.2.1
func UseColour() bool
UseColour checks if output is a terminal or whether colour output has been suppresed in env.
func UserDataDir ¶ added in v0.3.0
UserDataDir returns the default root directory to use for user-specific data. Users should create their own application-specific subdirectory within this one and use that.
On Unix systems, it returns $XDG_DATA_HOME as specified by https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html if non-empty, else $HOME/.local/share.
If the location cannot be determined (for example, $HOME is not defined) or the path in $XDG_DATA_HOME is relative, then it will return an error.
