- x get Haskell installed on Hetzner Arch machine
- What is the suggested way of setting up Haskell on Archlinux?
- "ghc is just the compiler; cabal is a build tool, and stack is tool built around cabal that includes a curated package repository"
- Haskell on Archlinux
- Native installation
- install ghc
- VIDEO: How to Install Haskell in Arch Linux
- just install compiler: Glasgow Haskell Compiler
sudo pacman -S ghc
- takes a long time to start up, seems stuck at 0%
- after 40 seconds it started installing
- then stopped at 99% for minutes
- got this error
- reading: ../Package_signing#Upgrade_system_regularlyhttps://wiki.archlinux.org/title/Pacman/Package_signing#Upgrade_system_regularly
- stopped install
sudo pacman -Sy archlinux-keyring && sudo pacman -Su- looks good
- again:
sudo pacman -S ghc- now looks good:

- create helloworld
- hello.hs
- main = print "Hello World"
- compile it
ghc -dynamic hello.hs
- run it
./hello
- hello.hs
- What is the suggested way of setting up Haskell on Archlinux?
- x write a simple Haskell script that contains a function
- x write a custom Haskell script that contains a function
- changed this up based on the above
- changed this up based on the above
- x create GitHub respository with all code
- on GitHub: created repository: et021-haskell-basics
- on Arch machine:
git init -b devgit remote add origin git@github.com:edwardtanguay/et021-haskell-basics.gitgit add .git commit -m "initial commit"git push -u origin dev
- worked: repo
- x create script to write to a file
- works:
- works:
- x learned list functions
- x create a subdomain url site on arch machine which shows index.html page created with Haskell script
- writeFile.hs
- import System.IOmain;IO ()main = dolet filePath = "/var/www/mainsite/haskell.html"let html = "this is a <b>test</b> of creating a website with Haskell222\n"writeFile filePath html
- writeFile.hs
- create two lists
- TODO:
- look at the npm for Haskell: ../cabalhttps://www.haskell.org/cabal
- learn Haskell ranges
- )) watch: Building a GTK App With Haskell
- .. learning Haskell language basics
- reading through Learn You a Haskell for Great Good!
- using tutorialspoint: Haskell
- the ghci (Glasgo Haskell Compiler Interactive) works:
- get out of ghci with CTRL-D
- create a function in file then load it
- doubleMe.hs
- doubleMe x = x + x
ghci:l doubleMe(las in load)
- doubleMe.hs
- trying other commands
- ++ add two lists
- : add to beginning of list (like unshift)
- !! get indexed item out
- head, tail, last, init (note there is not first)
- length, null, reverse, take, drop
- ++ add two lists
- )) video: ../watch?v=LnX3B9oaKzwhttps://www.youtube.com/watch?v=LnX3B9oaKzw
- )) create a script that creates a full webpage with HTML/CSS/JS
- DOING:
- x use lists in site generation
- x use list in code
- x create a UL/LI list
- x rename to haskgen.hs
- x make ability to show output from block in function
- x format with styles
- x add GitHub link
- x organize site
- x add foray link
- x add newlines
- x add links at bottom
- x make examples of list functions
- x clean up
- x make module of little used functions
- .. ranges
- continue with the book: ../starting-out#texas-rangeshttp://learnyouahaskell.com/starting-out#texas-ranges
- x use lists in site generation
