Strings helpers
Strings
Atof(string) float64
Parses a string representation of a float number to an actual float number (binding on strconv.ParseFloat
)
Atof(evt.Parsed.tcp_port)
Upper(string) string
Returns the uppercase version of the string
Upper("yop")
Lower(string) string
Returns the lowercase version of the string
Lower("YOP")
ParseUri(string) map[string][]string
Parses an URI into a map of string list.
ParseURI("/foo?a=1&b=2")
would return :
{
"a": []string{"1"},
"b": []string{"2"}
}
PathUnescape(string) string
PathUnescape
does the inverse transformation of PathEscape, converting each 3-byte encoded substring of the form "%AB" into the hex-decoded byte 0xAB. It returns an error if any % is not followed by two hexadecimal digits.
PathEscape(string) string
PathEscape
escapes the string so it can be safely placed inside a URL path segment, replacing special characters (including /) with %XX sequences as needed.
QueryUnescape(string) string
QueryUnescape
does the inverse transformation of QueryEscape, converting each 3-byte encoded substring of the form "%AB" into the hex-decoded byte 0xAB. It returns an error if any % is not followed by two hexadecimal digits.
QueryEscape(string) string
QueryEscape
escapes the string so it can be safely placed inside a URL query.
Sprintf(format string, a ...interface{}) string
Official doc : Sprintf formats according to a format specifier and returns the resulting string.
Sprintf('%dh', 1)
returns1h
Match(pattern string, object string) bool
Match
returns true if the object string matches the pattern. Pattern only supports wildcard :
*
multi-character wildcard (including zero-length)?
single character wildcard
Match('to?o*', 'totoooooo')
returnstrue
Fields(s string) []string
Fields
splits the string s around each instance of one or more consecutive white space characters, as defined by unicode.IsSpace, returning a slice of substrings of s or an empty slice if s contains only white space.
Index(s string, substr string) int
Index returns the index of the first instance of substr in s, or -1 if substr is not present in s.
IndexAny(s string, chars string) int
IndexAny returns the index of the first instance of any Unicode code point from chars in s, or -1 if no Unicode code point from chars is present in s.
Join(elems []string, sep string) string
Join concatenates the elements of its first argument to create a single string. The separator string sep is placed between elements in the resulting string.
Split(s string, sep string) []string
Split slices s into all substrings separated by sep and returns a slice of the substrings between those separators.
If s does not contain sep and sep is not empty, Split returns a slice of length 1 whose only element is s.
If sep is empty, Split splits after each UTF-8 sequence. If both s and sep are empty, Split returns an empty slice.
It is equivalent to SplitN with a count of -1.
To split around the first instance of a separator, see Cut.
SplitAfter(s string, sep string) []string
SplitAfter slices s into all substrings after each instance of sep and returns a slice of those substrings.
If s does not contain sep and sep is not empty, SplitAfter returns a slice of length 1 whose only element is s.
If sep is empty, SplitAfter splits after each UTF-8 sequence. If both s and sep are empty, SplitAfter returns an empty slice.
It is equivalent to SplitAfterN with a count of -1.
SplitAfterN(s string, sep string, n int) []string
SplitAfterN slices s into substrings after each instance of sep and returns a slice of those substrings.
The count determines the number of substrings to return:
n > 0: at most n substrings; the last substring will be the unsplit remainder.
n == 0: the result is nil (zero substrings)
n < 0: all substrings
Edge cases for s and sep (for example, empty strings) are handled as described in the documentation for SplitAfter.
SplitN(s string, sep string, n int) []string
SplitN slices s into substrings separated by sep and returns a slice of the substrings between those separators.
The count determines the number of substrings to return:
n > 0: at most n substrings; the last substring will be the unsplit remainder.
n == 0: the result is nil (zero substrings)
n < 0: all substrings
Edge cases for s and sep (for example, empty strings) are handled as described in the documentation for Split.
To split around the first instance of a separator, see Cut.
Replace(s string, old string, new string, n int) string
Replace returns a copy of the string s with the first n non-overlapping instances of old replaced by new. If old is empty, it matches at the beginning of the string and after each UTF-8 sequence, yielding up to k+1 replacements for a k-rune string. If n < 0, there is no limit on the number of replacements.
ReplaceAll(s string, old string, new string) string
ReplaceAll returns a copy of the string s with all non-overlapping instances of old replaced by new. If old is empty, it matches at the beginning of the string and after each UTF-8 sequence, yielding up to k+1 replacements for a k-rune string.
Trim(s string, cutset string) string
Trim returns a slice of the string s with all leading and trailing Unicode code points contained in cutset removed.
TrimLeft(s string, cutset string) string
TrimLeft returns a slice of the string s with all leading Unicode code points contained in cutset removed.
To remove a prefix, use TrimPrefix instead.
TrimRight(s string, cutset string) string
TrimRight returns a slice of the string s, with all trailing Unicode code points contained in cutset removed.
To remove a suffix, use TrimSuffix instead.
TrimSpace(s string) string
TrimSpace returns a slice of the string s, with all leading and trailing white space removed, as defined by Unicode.
TrimPrefix(s string, prefix string) string
TrimPrefix returns s without the provided leading prefix string. If s doesn't start with prefix, s is returned unchanged.
TrimSuffix(s string, suffix string) string
TrimSuffix returns s without the provided trailing suffix string. If s doesn't end with suffix, s is returned unchanged.
ToString(s) string
Returns the string representation of s, if available (does a s.(sttring)
).
LogInfo(format string, ...)
Performs a logging call with the provided parameters, see logrus reference for formatting info.
