PureShell… First Light

Posted on June 27, 2022

I’ve been working on a PureScript back-end targeting Bash, which I call PureShell. And I now have all stages working, so I can turn this

module Example.Literals where

foo :: String
foo = "Hello"

bar :: String
bar = "There is no cheese ✓"

baz :: String
baz = "$baz"

α :: String
α = "alpha"

foo' :: String
foo' = "BOOM"

into this

set -o errexit -o nounset -o pipefail

function p206p177 {
  echo alpha
function foop39 {
  echo BOOM
function foo {
  echo Hello
function baz {
  echo $'$baz'
function bar {
  echo $'There is no cheese \xE2\x9C\x93'

This is about all it can do for now though, since the first lowering stage is still very incomplete.
