Here "data source" means simple collections like Lists or +Vectors, +but also potentially large files or generators of infinite data. + +Transducers… + +- allow the chaining of operations like map and filter without allocating memory between each step. +- aren't tied to any specific data type; they need only be implemented once. +- vastly simplify "data transformation code". +- have nothing to do with "lazy evaluation". +- are a joy to use! + +In this talk, Colin will introduce Transducers, show how to use them, and +demonstrate some Emacs-specific workflows that make live processing of large +data sets in JSON and CSV a breeze. + +About the speaker: + +Colin has been active in the FOSS world since 2011, publishing libraries and +applications primarily in Haskell and Rust. Since 2023 he has been using +Lisps +more and more, and after falling in love with Transducers from Clojure has +ported the pattern to three other Lisps. + +Colin is originally from Canada and lives in Japan. + + + +[[!inline pages="internal(2024/info/transducers-after)" raw="yes"]] + +[[!inline pages="internal(2024/info/transducers-nav)" raw="yes"]] + + |
