text := import("text")re_match(pattern string, text string) => bool/error: reports whether the string s contains any match of the regular expression pattern.re_find(pattern string, text string, count int) => [[{text: string, begin: int, end: int}]]/undefined: returns an array holding all matches, each of which is an array of map object that contains matching text, begin and end (exclusive) index.re_replace(pattern string, text string, repl string) => string/error: returns a copy of src, replacing matches of the pattern with the replacement string repl.re_split(pattern string, text string, count int) => [string]/error: slices s into substrings separated by the expression and returns a slice of the substrings between those expression matches.re_compile(pattern string) => Regexp/error: parses a regular expression and returns, if successful, a Regexp object that can be used to match against text.compare(a string, b string) => int: returns an integer comparing two strings lexicographically. The result will be 0 if a==b, -1 if a < b, and +1 if a > b.contains(s string, substr string) => bool: reports whether substr is within s.contains_any(s string, chars string) => bool: reports whether any Unicode code points in chars are within s.count(s string, substr string) => int: counts the number of non-overlapping instances of substr in s.equal_fold(s string, t string) => bool: reports whether s and t, interpreted as UTF-8 strings,fields(s string) => [string]: 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.has_prefix(s string, prefix string) => bool: tests whether the string s begins with prefix.has_suffix(s string, suffix string) => bool: tests whether the string s ends with suffix.index(s string, substr string) => int: returns the index of the first instance of substr in s, or -1 if substr is not present in s.index_any(s string, chars string) => int: 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(arr string, sep string) => string: concatenates the elements of a to create a single string. The separator string sep is placed between elements in the resulting string.last_index(s string, substr string) => int: returns the index of the last instance of substr in s, or -1 if substr is not present in s.last_index_any(s string, chars string) => int: returns the index of the last instance of any Unicode code point from chars in s, or -1 if no Unicode code point from chars is present in s.repeat(s string, count int) => string: returns a new string consisting of count copies of the string s.replace(s string, old string, new string, n int) => string: returns a copy of the string s with the first n non-overlapping instances of old replaced by new.substr(s string, lower int, upper int) => string => string: returns a substring of the string s specified by the lower and upper parameters.split(s string, sep string) => [string]: slices s into all substrings separated by sep and returns a slice of the substrings between those separators.split_after(s string, sep string) => [string]: slices s into all substrings after each instance of sep and returns a slice of those substrings.split_after_n(s string, sep string, n int) => [string]: slices s into substrings after each instance of sep and returns a slice of those substrings.split_n(s string, sep string, n int) => [string]: slices s into substrings separated by sep and returns a slice of the substrings between those separators.title(s string) => string: returns a copy of the string s with all Unicode letters that begin words mapped to their title case.to_lower(s string) => string: returns a copy of the string s with all Unicode letters mapped to their lower case.to_title(s string) => string: returns a copy of the string s with all Unicode letters mapped to their title case.to_upper(s string) => string: returns a copy of the string s with all Unicode letters mapped to their upper case.pad_left(s string, pad_len int, pad_with string) => string: returns a copy of the string s padded on the left with the contents of the string pad_with to length pad_len. If pad_with is not specified, white space is used as the default padding.pad_right(s string, pad_len int, pad_with string) => string: returns a copy of the string s padded on the right with the contents of the string pad_with to length pad_len. If pad_with is not specified, white space is used as the default padding.trim(s string, cutset string) => string: returns a slice of the string s with all leading and trailing Unicode code points contained in cutset removed.trim_left(s string, cutset string) => string: returns a slice of the string s with all leading Unicode code points contained in cutset removed.trim_prefix(s string, prefix string) => string: returns s without the provided leading prefix string.trim_right(s string, cutset string) => string: returns a slice of the string s, with all trailing Unicode code points contained in cutset removed.trim_space(s string) => string: returns a slice of the string s, with all leading and trailing white space removed, as defined by Unicode.trim_suffix(s string, suffix string) => string: returns s without the provided trailing suffix string.atoi(str string) => int/error: returns the result of ParseInt(s, 10, 0) converted to type int.format_bool(b bool) => string: returns "true" or "false" according to the value of b.format_float(f float, fmt string, prec int, bits int) => string: converts the floating-point number f to a string, according to the format fmt and precision prec.format_int(i int, base int) => string: returns the string representation of i in the given base, for 2 <= base <= 36. The result uses the lower-case letters 'a' to 'z' for digit values >= 10.itoa(i int) => string: is shorthand for format_int(i, 10).parse_bool(s string) => bool/error: returns the boolean value represented by the string. It accepts 1, t, T, TRUE, true, True, 0, f, F, FALSE, false, False. Any other value returns an error.parse_float(s string, bits int) => float/error: converts the string s to a floating-point number with the precision specified by bitSize: 32 for float32, or 64 for float64. When bitSize=32, the result still has type float64, but it will be convertible to float32 without changing its value.parse_int(s string, base int, bits int) => int/error: interprets a string s in the given base (0, 2 to 36) and bit size (0 to 64) and returns the corresponding value i.quote(s string) => string: returns a double-quoted Go string literal representing s. The returned string uses Go escape sequences (\t, \n, \xFF, \u0100) for control characters and non-printable characters as defined by IsPrint.unquote(s string) => string/error: interprets s as a single-quoted, double-quoted, or backquoted Go string literal, returning the string value that s quotes. (If s is single-quoted, it would be a Go character literal; Unquote returns the corresponding one-character string.)
match(text string) => bool: reports whether the string s contains any match of the regular expression pattern.find(text string, count int) => [[{text: string, begin: int, end: int}]]/undefined: returns an array holding all matches, each of which is an array of map object that contains matching text, begin and end (exclusive) index.replace(src string, repl string) => string: returns a copy of src, replacing matches of the pattern with the replacement string repl.split(text string, count int) => [string]: slices s into substrings separated by the expression and returns a slice of the substrings between those expression matches.
