Current Features for common
This package collates basic broad functions that are used throughout this codebase.
- Coding example
import "github.com/idoall/gocryptotrader/common"
testString := "aAaAa"
upper := strings.ToUpper(testString)
// upper == "AAAAA"

Constants ¶
const ( // SimpleTimeFormat a common, but non-implemented time format in golang SimpleTimeFormat = "2006-01-02 15:04:05" // SimpleTimeFormatWithTimezone a common, but non-implemented time format in golang SimpleTimeFormatWithTimezone = "2006-01-02 15:04:05 MST" // GctExt is the extension for GCT Tengo script files GctExt = ".gct" )
Variables ¶
var ( // ErrNotYetImplemented defines a common error across the code base that // alerts of a function that has not been completed or tied into main code ErrNotYetImplemented = errors.New("not yet implemented") // ErrFunctionNotSupported defines a standardised error for an unsupported // wrapper function by an API ErrFunctionNotSupported = errors.New("unsupported wrapper function") // ErrDateUnset is an error for start end check calculations ErrDateUnset = errors.New("date unset") // ErrStartAfterEnd is an error for start end check calculations ErrStartAfterEnd = errors.New("start date after end date") // ErrStartEqualsEnd is an error for start end check calculations ErrStartEqualsEnd = errors.New("start date equals end date") // ErrStartAfterTimeNow is an error for start end check calculations ErrStartAfterTimeNow = errors.New("start date is after current time") // ErrNilPointer defines an error for a nil pointer ErrNilPointer = errors.New("nil pointer") )
Vars for common.go operations
Functions ¶
func ChangePermission ¶
ChangePermission lists all the directories and files in an array
func EncodeURLValues ¶
EncodeURLValues concatenates url values onto a url string and returns a string
func ExtractHost ¶
ExtractHost returns the hostname out of a string
func ExtractPort ¶
ExtractPort returns the port name out of a string
func GetDefaultDataDir ¶
GetDefaultDataDir returns the default data directory Windows - C:\Users\%USER%\AppData\Roaming\GoCryptoTrader Linux/Unix or OSX - $HOME/.gocryptotrader
func GetExecutablePath ¶
GetExecutablePath returns the executables launch path
func GetURIPath ¶
GetURIPath returns the path of a URL given a URI
func IsEnabled ¶
IsEnabled takes in a boolean param and returns a string if it is enabled or disabled
func IsValidCryptoAddress ¶
IsValidCryptoAddress validates your cryptocurrency address string using the regexp package // Validation issues occurring because "3" is contained in litecoin and Bitcoin addresses - non-fatal
func NewHTTPClientWithTimeout ¶
NewHTTPClientWithTimeout initialises a new HTTP client and its underlying transport IdleConnTimeout with the specified timeout duration
func SendHTTPRequest ¶
func SendHTTPRequest(ctx context.Context, method, urlPath string, headers map[string]string, body io.Reader, verbose bool) ([]byte, error)
SendHTTPRequest sends a request using the http package and returns the body contents
func SetHTTPClient ¶

func SetHTTPClientWithTimeout ¶
SetHTTPClientWithTimeout sets a new *http.Client with different timeout settings
func SetHTTPUserAgent ¶
SetHTTPUserAgent sets the user agent which will be used for all common HTTP requests.
func SplitStringSliceByLimit ¶
SplitStringSliceByLimit splits a slice of strings into slices by input limit and returns a slice of slice of strings
func StartEndTimeCheck ¶
StartEndTimeCheck provides some basic checks which occur frequently in the codebase
func StringDataCompare ¶
StringDataCompare data checks the substring array with an input and returns a bool
func StringDataCompareInsensitive ¶
StringDataCompareInsensitive data checks the substring array with an input and returns a bool irrespective of lower or upper case strings
func StringDataContains ¶
