Code it later

Why

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.

Install

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

Usage

As same as clojure version, so please check clojure version

Features those still developing:

• output to org file
• expand other languages json file

Features only in this version

-dx {folder_name} or --ignore-dir {folder_name} will ignore all files in {folder_name}

Next

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.
