juvix/notes

Tools used so far:

• cabal-edit

• hlint

• stan

• summoner

• ghcup

• implicit-hie generates hie.yaml.

• For Pretty printer, we will use the package https://hackage.haskell.org/package/prettyprinter, which supports nice annotations and colors using Ansi-terminal subpackage: cabal-edit add prettyprinter-ansi-terminal.

• Two options for the kind of container we can use for Context. Using the package container and for performance, unordered-containers. The latter seems to have the same API naming than the former. So, in principle, it doesn't matter which we use.

• See gluedeval. During elaboration different kind of evaluation strategies may be needed.

  • top vs. local scope.

• On equality type-checking, see abstract

• To document the code, see https://kowainik.github.io/posts/haddock-tips

Initial task order for Minijuvix indicated between parenthesis:

1. Parser (3.)
2. Typechecker (1.)
3. Compiler (2.)
4. Interpreter (4.)

• On deriving stuff using Standalone Der. See https://kowainik.github.io/posts/deriving.

• To avoid boilerplate in the cabal file, one could use common stanzas. At the moment, I'm using cabal-edit to keep the bounds and this tool does not support stanzas. So be it.

• Using MultiParamTypeClasses to allow me deriving multi instances in one line.

• TODO: make a ref.bib listing all the repositories and the source-code from where I took code, inspiration, whatever thing.
