Functions

func CidBaseDefined

func CidBaseDefined(req *cmds.Request) bool

CidBaseDefined returns true if the `cid-base` option is specified on the command line

func CidEncoderFromPath

func CidEncoderFromPath(p string) (cidenc.Encoder, error)

CidEncoderFromPath creates a new encoder that is influenced from the encoded Cid in a Path. For CidV0 the multibase from the base encoder is used and automatic upgrades are disabled. For CidV1 the multibase from the CID is used and upgrades are enabled.

This logic is intentionally fuzzy and will match anything of the form `CidLike`, `CidLike/...`, or `/namespace/CidLike/...`.

For example:

* Qm... * Qm.../... * /ipfs/Qm... * /ipns/bafybeiahnxfi7fpmr5wtxs2imx4abnyn7fdxeiox7xxjem6zuiioqkh6zi/... * /bzz/bafybeiahnxfi7fpmr5wtxs2imx4abnyn7fdxeiox7xxjem6zuiioqkh6zi/...

func EscNonPrint

func EscNonPrint(s string) string

EscNonPrint converts non-printable characters and backslash into Go escape sequences. This is done to display all characters in a string, including those that would otherwise not be displayed or have an undesirable effect on the display.

func GetApi

func GetApi(env cmds.Environment, req *cmds.Request) (coreiface.CoreAPI, error)

GetApi extracts CoreAPI instance from the environment.

func GetCidEncoder

func GetCidEncoder(req *cmds.Request) (cidenc.Encoder, error)

GetCidEncoder processes the `cid-base` and `output-cidv1` options and returns a encoder to use based on those parameters.

func GetConfigRoot

func GetConfigRoot(env cmds.Environment) (string, error)

GetConfigRoot extracts the config root from the environment

func GetFileArg

func GetFileArg(it files.DirIterator) (files.File, error)

GetFileArg returns the next file from the directory or an error

func GetLowLevelCidEncoder

func GetLowLevelCidEncoder(req *cmds.Request) (cidenc.Encoder, error)

GetLowLevelCidEncoder is like GetCidEncoder but meant to be used by lower level commands. It differs from GetCidEncoder in that CIDv0 are not, by default, auto-upgraded to CIDv1.

func GetNode

func GetNode(env interface{}) (*core.IpfsNode, error)

GetNode extracts the node from the environment.
