I already have other versions:
- code_it_later_ml ocaml version
- code-it-later clojure version
- code-it-later-rs rust version
so why I write this version. Because after I finish first ocaml version, I thought why not haskell. Then I start this repo.
After this version, I find something:
small input: haskell faster than ocaml (just a little), and clojure version is slow.
big input: clojure is fastest, haskell is faster than ocaml.
===================================
update from 1/27/2019
I make this version become concurrency version. And tested with same input:
- clojure version: cost 2.2 second, ~200% cpu cost.
- ocaml version: cost 2.2 second, 100% cpu cost.
- this haskell version: cost 0.6 seconds, 140% cpu cost.
I am satisfied about this result. And change haskell code to concurrency is not that hard.
update from 5/8/2020
after ghc 8.10 add -xn to active new GC in runtime.
code-it-later-hs.cabal including all build configuration which cabal need.
use cabal new-install to install
cabal new-install -O2 --installdir=/usr/local/bin .then
cp ./codeitlater /usr/local/bin/
after install, codeitlater should in your /usr/local/bin/codeitlater
As same as clojure version, so please check clojure version
Features those still developing:
- output to org file
- expand other languages json file
-dx {folder_name} or --ignore-dir {folder_name} will ignore all files in {folder_name}
ocaml looks like not very convenient for using parallel. I will try parallel in this haskell version for practice.
I do not use parallel, I make it concurrency with mutil-core, and it is good enough.
