String methods
You can find more info about the particular regex syntax used in the *_regex methods on this link.
.to_uppercase()
Return the same string in all uppercase characters.
string.to_uppercase() => String
// example
do val = "Where is Brian?"
do val.to_uppercase() // "WHERE IS BRIAN?".to_lowercase()
Return the same string in all lowercase characters.
string.to_lowercase() => String
// example
do val = "Where is Brian?"
do val.to_lowercase() // "where is brian?".capitalize()
Return the same string with the first letter in uppercase. The rest of the string remains unchanged.
string.capitalize() => String
// example
do val = "my name is John"
do val.capitalize() // "My name is John".trim(), .trim_left(), .trim_right()
Returns a new string with both leading and trailing whitespace removed. .trim_left() and .trim_right() only trim the leading and trainling whitespace respectively.
do text = " Where is Brian? "
do new_text = text.trim()
say new_text // "Where is Brian?"
do new_text = text.trim_left()
say new_text // "Where is Brian? "
do new_text = text.trim_right()
say new_text // " Where is Brian?".length()
Return the length of the target string.
string.length() => Integer
// example
do val = "Where is Brian?"
do val.length() // 15.contains(String), .contains_regex(String)
Return whether the string contains another string or expression.
haystack.contains(needle) => Boolean
haystack.contains_regex(needle) => Boolean
// example
do val = "Where is Brian?"
// does it contain any "r"?
do val.contains("r") // true
// does it contain the word "where"?
do val.contains("where") // false => no, because it is case sensitive
// does it contain any number?
do val.contains_regex("[0-9]") // true.replace(), .replace_all(), .replace_regex()
Replace the first, all or any occurrence matching the predicate:
say "toto".replace("o", "a") // "tato" the first o char is replaced
say "toto".replace_all("o", "a") // "tata" all o chars are replaced
say "toto".replace_regex("[to]", "a") // "aaaa" all chars that are t or o are replaced.starts_with(String), .starts_with_regex(String)
Return whether a string starts with another string or expression.
haystack.starts_with(needle) => Boolean
haystack.starts_with_regex(needle) => Boolean
// example
do val = "Where is Brian?"
// does it start with "r"?
do val.starts_with("r") // false
// does it start with any uppercase letter?
do val.starts_with_regex("[A-Z]") // true.ends_with(String), .ends_with_regex(String)
Return whether a string ends with another string or expression.
haystack.ends_with(needle) => Boolean
haystack.ends_with_regex(needle) => Boolean
// example
do val = "Where is Brian?"
// does it end with "r"?
do val.ends_with("r") // false
// does it end with any uppercase letter?
do val.ends_with_regex("[A-Z]") // false.match(String), .match_regex(String)
Return all the matches of the string or expression in the target string, or Null if none are found.
haystack.match(needle) => Array[String]
haystack.match_regex(needle) => Array[String]
// example
do val = "Where is Brian?"
// does it match with "r"?
do val.match("r") // ["r", "r"] => yes, twice!
// does it match with any uppercase letter?
do val.match_regex("[A-Z]") // ["W", "B"] => yes, and these are the letters!.is_number(), .is_int(), .is_float()
Return whether the given string represents a numerical value, an int, a float.
string.is_number() => Boolean
// example
do val = "Where is Brian?"
do val.is_number() // false
do val = "42"
do val.is_number() // true
do val.is_int() // true
do val.is_float() // false.split(String)
Split a string by a given separator and return an array containing all elements in order. The separator can be a single or multiple characters. If the separator can not be found in the string, the returned array will only contain the original string.
string.split(String) => Array[String]
// example
do val = "this is a long string"
do val.split(" ") // ["this", "is", "a", "long", "string"]
do val.split("is") // ["th", " ", " a long string"]
do val.split("camembert") // ["this is a long string"].slice(start, end) => String
Cut a string between the start and end characters. Some rules apply:
If
endis not specified, all the characters afterstartare returned.When specified,
endmust be ≥start.If any of the parameters is < 0, the count is made from the end of the string.
say "abcdefghijklmnop".slice(2, 4) // "cd"
say "abcdefghijklmnop".slice(7) // "hijklmnop"
say "abcdefghijklmnop".slice(-4) // "mnop"
say "abcdefghijklmnop".slice(-4, 14) // "mn"
say "abcdefghijklmnop".slice(-4, 3) // Error
say "abcdefghijklmnop".slice(2, 1) // Error.to_int(), .to_float() => Integer, Float
Convert a string representing a number to a value cast as an integer or float:
do val = "1.2345".to_int() // 1
do val = "1.2345".to_float() // 1.2345
do val = "not a number".to_int() // error.to_yml(), .to_json()
Convert yaml to json and back
do json = "some:\n yaml: 1".to_json()
say "{{json}}" // {"some":{"yaml":1}}
do yml = json.to_yaml()
say "{{yml}}" // some:\n yaml: 1.encode_uri(), .encode_uri_component(), .decode_uri(), .decode_uri_component()
