How to improve your Lisp code? Launch linters! [EN Subs]

Listen Later

In this video I show how to run linters for Common Lisp code and get constructive criticism from them.

We will look at 3 types of checks: warnings from the compiler, checking for unspecified or unnecessary dependencies, and analyzing the idiomaticity of the code.

As a bonus, I will tell you about the 40ANTS-CI system, which simplifies the launch of linters, tests and the assembly of documentation for Common Lisp projects. I use it on all my projects and it greatly simplifies my life in terms of setting up GitHub Actions.

Commands for installing linters:

ros install 40ants-asdf-system 40ants-critic

ros install 40ants-asdf-system 40ants-linter

Before installing, you need to add a distribution kit to the quicklisp client settings Ultralisp.org:

(ql-dist:install-dist "http://dist.ultralisp.org/"

:prompt nil)
