all-prefixes clj

(all-prefixes w)

(all-prefixes pred w)

Generates a lazy sequence of all possible prefixes of a given string. Returns nil if nil or an empty string was given as an argument instead of a string.

Objects of the following types which are passed as a last argument are coerced to strings: characters, numbers, sequences of characters, collections of strings, collections of characters, collections of numbers. For collections it joins the elements converted to strings.

The resulting sequence will contain the original string on its last position.

If two arguments are given the first one should be a function used to partition the given string. It should take a single character and return an object. The given string will be split whenever this function will return a new value. That way the prefixes will be generated for parts of the string instead of separate characters.

Objects of the following types which are passed as a first argument of 2-arity version are coerced to a slicing predicate: characters, numbers, strings, sequences of characters, collections of strings, collections of characters, collections of numbers. It splits them into single-character elements and creates a sets to be used as functions. In case of a single character it creates a small predicate function. For nil it will create a function that won't match anything. Same for empty collections or strings.

all-subs clj

(all-subs w)

(all-subs pred w)

Generates a lazy sequence of all possible substrings (prefixes, suffixes and infixes) of a given string. Returns nil if nil or an empty string was given as an argument instead of a string.

Objects of the following types which are passed as a last argument are coerced to strings: characters, numbers, sequences of characters, collections of strings, collections of characters, collections of numbers. For collections it joins the elements converted to strings.

The resulting sequence will contain the original string in its middle. Moreover, the substrings will not be unique across the sequence if the characters are repeating in the input.

If two arguments are given the first one should be a function used to partition the given string. It should take a single character and return an object. The given string will be split whenever this function will return a new value. That way the substrings will be generated for parts of the string instead of separate characters.

For nil it will create a function that won't match anything. Same for empty collections or strings.

all-suffixes clj

(all-suffixes w)

(all-suffixes pred w)

Generates a lazy sequence of all possible suffixes of a given string. Returns nil if nil or an empty string was given as an argument instead of a string.

Objects of the following types which are passed as a last argument are coerced to strings: characters, numbers, sequences of characters, collections of strings, collections of characters, collections of numbers. For collections it joins the elements converted to strings.

The resulting sequence will contain the original string on its first position.

trim-both clj

(trim-both w)

(trim-both matcher w)

(trim-both start end w)

Takes a string and recursively trims its first and last character if they are equal. Returns a new string or nil (when nil was passed as an argument instead of a string). For an empty string it returns an empty string.

Objects of the following types that are passed as a last argument are coerced to strings: characters, numbers, sequences of characters, collections of strings, collections of characters, collections of numbers. For collections it joins the elements converted to strings.

When 2 arguments are given the first one should be a character matching function used to decide whether to trim first and last character. It should take a single character and make a lookup to decide whether this character should be trimmed from the beginning of a string. Additionally, the returned value is used to match the last character of the string. Therefore the returned value should be a character (the same or different as passed), nil or false (to indicate a failed match). The trimming function will trim a string on both ends if a value returned by the matcher is equal to the last character of this string. It's common to use a set (to match the same characters on both ends) or a map (to match different characters).

Objects of the following types that are passed as a first argument of 2-arity variant are coerced to a matching function: characters, numbers, strings, sequences of characters, collections of strings, collections of characters, collections of numbers. It splits them into single-character elements and creates a sets to be used as functions. In case of single characters it creates a small predicate function. For nil it will create a function that won't match anything. Same for empty collections or strings.

When 3 arguments are given the first two should be characters used to match first and last character of a trimmed string (given as third argument).

When the string consist of 2 matching letters the result will be an empty string.

trim-both-once clj

(trim-both-once w)

(trim-both-once matcher w)

(trim-both-once start end w)

Takes a string and trims its first and last character if they are equal. Returns a new string or original string if there is nothing to trim. For nil it returns nil.

Objects of the following types that are passed as a last argument are coerced to strings: characters, numbers, sequences of characters, collections of strings, collections of characters, collections of numbers. For collections it joins the elements converted to strings.

trim-both-once-with-orig clj

(trim-both-once-with-orig w)

(trim-both-once-with-orig matcher w)

(trim-both-once-with-orig start end w)

Takes a string and trims its first and last character if they are equal. Returns a 2-element sequence containing a new string and the original one. If there is nothing to trim it returns a sequence with just 1 element. For nil it returns nil.

Objects of the following types that are passed as a last argument are coerced to strings: characters, numbers, sequences of characters, collections of strings, collections of characters, collections of numbers. For collections it joins the elements converted to strings.
