Warning: These are just my personal working notes as I learn Clojure, coming from Racket.

• Racket -> Clojure Given a Racket function, what's the clojure.core equivalent?

Note: This only includes things with a different name or behavior.

| Racket | Clojure | Comment | |--------------------------------+----------------------+----------------------------------------| | begin | do | | | print | prn | | | display | print | | | write | write | | | pretty-print | pprint | clojure.pprint | | curry | partial | | | curryr | N/A | | | negate | complement | | | andmap | every? | | | ormap | some | Returns 1st item not #t | | (length xs) | (count coll) | Note: list vs collection. | | count | N/A ? | | | append | concat | | | (take xs n) | (take n coll) | Note: args reversed | | takef | take-while | Note: args reversed | | hash | hash-map or {} | | | set | hash-set or #{} | | | vector | vector or [] | | | unless | when-not | | | #t or true | true | | | #f or false | false | | | format | format | ~s vs %s. See also: str | | for | doseq | for-effect iteration form | | for/list etc. | for | Note: specific vs. generic collections | | , | ~ | | | unquote | ~ | | | ,@ | ~@ | | | unquote-splicing | ~@ | | | partition | N/A | Clj partition different | | regexp pregexp | re-matches | Implicit ^ and $ | | regexp pregexp | re-find | No implicit ^ and $ | | regexp-match* | re-seq | | | regexp-replace* | replace | | | #rx"\w" | #"\w" | Clj regexps ~= px (?) | | #px"\w" | #"\w" | Note 2 vs. 1 backslashes | | string->symbol | symbol | | | symbol->string | str | | | #:keyword | :keyword | | | keyword->string | name or str | | | string->keyword | keyword | | | dict-values | vals | | | hash-values | vals | | | dict-keys | keys | | | hash-keys | keys | | | generics | protocols | approximately | | (define x (make-parameter 10)) | (def ^:dynamic x 10) | | | (parameterize ([x 42]) ___) | (binding [x 42] ___) | |

• Clojure -> Racket See table above.

Also some clojure.core functions are available in [[https://github.com/greghendershott/rackjure/][#lang rackjure]]:

| Function | Comment | |-----------------+-------------------------------------------------------| | { k v ... ... } | Dictionary literal. | | (dict key) | Applicable dictionaries. | | (key dict) | Applicable dictionaries. | | ~> and ~>> | Threading macros. -> is contract combinator in Racket | | #(+ % 2) | #λ(+ % 2) -- #λ() b/c #() is array literal in Racket | | str | | | swap! | | | partial | | | | |

NOTE: The following work with lists not collections.

| Function | Comment | |-----------------+-------------------------------------------------------| | partition | Clojure partition unlike Racket's | | (take<= xs n) | When < n avail, returns '() instead of erroring. | | juxt | | | every? | Alias for andmap | | some | ormap returns #t or #f. some returns first item or #f | | | |
