This package uses type constraints defined by:
METHODS
This package implements the following methods.
append
append() : StrObject
The append method modifies and returns the string with the argument list appended to it separated using spaces. This method returns a string object.
camelcase
camelcase() : StrObject
The camelcase method modifies the string such that it will no longer have any non-alphanumeric characters and each word (group of alphanumeric characters separated by 1 or more non-alphanumeric characters) is capitalized. Note, this method modifies the string. This method returns a Data::Object::String object.
chomp
chomp() : StrObject
The chomp method is a safer version of the chop method, it's used to remove the newline (or the current value of $/) from the end of the string. Note, this method modifies and returns the string. This method returns a string object.
chop
chop() : StrObject
The chop method removes the last character of a string and returns the character chopped. It is much more efficient than "s/.$//s" because it neither scans nor copies the string. Note, this method modifies and returns the string. This method returns a string value.
concat
concat(Any $arg1) : StrObject
The concat method modifies and returns the string with the argument list appended to it. This method returns a string value.
contains
contains(Str | RegexpRef $arg1) : NumObject
The contains method searches the string for the string specified in the argument and returns true if found, otherwise returns false. If the argument is a string, the search will be performed using the core index function. If the argument is a regular expression reference, the search will be performed using the regular expression engine. This method returns a Data::Object::Number object.
- contains example
-
# given 'Nullam ultrices placerat nibh vel malesuada.' $string->contains('trices'); # 1; true $string->contains('itrices'); # 0; false $string->contains(qr/trices/); # 1; true $string->contains(qr/itrices/); # 0; false
defined
defined() : NumObject
The defined method returns true if the object represents a value that meets the criteria for being defined, otherwise it returns false. This method returns a number object.
eq
eq(Any $arg1) : NumObject
The eq method returns true if the argument provided is equal to the value represented by the object. This method returns a number value.
ge
ge(Any $arg1) : NumObject
The ge method returns true if the argument provided is greater-than or equal-to the value represented by the object. This method returns a Data::Object::Number object.
gt
gt(Any $arg1) : NumObject
The gt method returns true if the argument provided is greater-than the value represented by the object. This method returns a number value.
hex
hex() : Str
The hex method returns the value resulting from interpreting the string as a hex string. This method returns a data type object to be determined after execution.
index
index(Str $arg1, Num $arg2) : NumObject
The index method searches for the argument within the string and returns the position of the first occurrence of the argument. This method optionally takes a second argument which would be the position within the string to start searching from (also known as the base). By default, starts searching from the beginning of the string. This method returns a data type object to be determined after execution.
- index example
-
# given 'unexplainable' $string->index('explain'); # 2 $string->index('explain', 0); # 2 $string->index('explain', 1); # 2 $string->index('explain', 2); # 2 $string->index('explain', 3); # -1 $string->index('explained'); # -1
lc
lc() : StrObject
The lc method returns a lowercased version of the string. This method returns a string object. This method is an alias to the lowercase method.
lcfirst
lc() : StrObject
The lcfirst method returns a the string with the first character lowercased. This method returns a string value.
le
le(Any $arg1) : NumObject
The le method returns true if the argument provided is less-than or equal-to the value represented by the object. This method returns a Data::Object::Number object.
length
length() : NumObject
The length method returns the number of characters within the string. This method returns a number value.
lines
lines() : ArrayObject
The lines method breaks the string into pieces, split on 1 or more newline characters, and returns an array reference consisting of the pieces. This method returns an array value.
- lines example
-
# given "who am i?\nwhere am i?\nhow did I get here" $string->lines; # ['who am i?','where am i?','how did i get here']
lowercase
lowercase() : StrObject
The lowercase method is an alias to the lc method. This method returns a string object.
lt
lt(Any $arg1) : NumObject
The lt method returns true if the argument provided is less-than the value represented by the object. This method returns a number value.
ne
ne(Any $arg1) : NumObject
The ne method returns true if the argument provided is not equal to the value represented by the object. This method returns a number value.
render
render(HashRef $arg1) : StrObject
The render method treats the string as a template and performs a simple token replacement using the argument provided.
replace
replace(Str $arg1, Str $arg2) : StrObject
The replace method performs a smart search and replace operation and returns the modified string (if any modification occurred). This method optionally takes a replacement modifier as it's final argument. Note, this operation expects the 2nd argument to be a replacement String. This method returns a string object.
- replace example
-
# given 'Hello World' $string->replace('World', 'Universe'); # Hello Universe $string->replace('world', 'Universe', 'i'); # Hello Universe $string->replace(qr/world/i, 'Universe'); # Hello Universe $string->replace(qr/.*/, 'Nada'); # Nada
reverse
reverse() : ArrayObject
The reverse method returns a string where the characters in the string are in the opposite order. This method returns a string value.
rindex
rindex(Str $arg1, Num $arg2) : NumObject
The rindex method searches for the argument within the string and returns the position of the last occurrence of the argument. This method optionally takes a second argument which would be the position within the string to start searching from (beginning at or before the position). By default, starts searching from the end of the string. This method returns a data type object to be determined after execution.
- rindex example
-
# given 'explain the unexplainable' $string->rindex('explain'); # 14 $string->rindex('explain', 0); # 0 $string->rindex('explain', 21); # 14 $string->rindex('explain', 22); # 14 $string->rindex('explain', 23); # 14 $string->rindex('explain', 20); # 14 $string->rindex('explain', 14); # 0 $string->rindex('explain', 13); # 0 $string->rindex('explain', 0); # 0 $string->rindex('explained'); # -1
snakecase
snakecase() : StrObject
The snakecase method modifies the string such that it will no longer have any non-alphanumeric characters and all words (groups of alphanumeric characters separated by 1 or more non-alphanumeric characters) are joined by a single underscore. This method returns a string value. Any leading or trailing underscores are removed.
split
split(RegexpRef $arg1, Num $arg2) : ArrayObject
The split method splits the string into a list of strings, separating each chunk by the argument (string or regexp object), and returns that list as an array reference. This method optionally takes a second argument which would be the limit (number of matches to capture). Note, this operation expects the 1st argument to be a Regexp object or a String. This method returns a array object.
- split example
-
# given 'name, age, dob, email' $string->split(', '); # ['name', 'age', 'dob', 'email'] $string->split(', ', 2); # ['name', 'age, dob, email'] $string->split(qr/\,\s*/); # ['name', 'age', 'dob', 'email'] $string->split(qr/\,\s*/, 2); # ['name', 'age, dob, email']
strip
strip() : StrObject
The strip method returns the string replacing occurences of 2 or more whitespaces with a single whitespace. This method returns a string object.
titlecase
titlecase() : StrObject
The titlecase method returns the string capitalizing the first character of each word (group of alphanumeric characters separated by 1 or more whitespaces). Note, this method modifies the string. This method returns a string object.
trim
trim() : StrObject
The trim method removes 1 or more consecutive leading and/or trailing spaces from the string. This method returns a string value.
uc
uc() : StrObject
The uc method returns an uppercased version of the string. This method returns a string object. This method is an alias to the uppercase method.
ucfirst
uc() : StrObject
The ucfirst method returns a the string with the first character uppercased. This method returns a string value.
uppercase
uppercase() : StrObject
The uppercase method is an alias to the uc method. This method returns a string object.
words
words() : ArrayObject
The words method splits the string into a list of strings, separating each group of characters by 1 or more consecutive spaces, and returns that list as an array reference. This method returns an array value.
- words example
-
# given "is this a bug we're experiencing" $string->words; # ["is","this","a","bug","we're","experiencing"]
