Meet new Sparrow plugin jinjalint to lint jinja templates.


Let's get started!

Setup a tom task

$ tom --edit jinja-lint
Enter fullscreen mode Exit fullscreen mode
task-run "lint my code", "jinjalint", %(
  args => [
    "templates/",
    ["verbose"]
  ]
);
Enter fullscreen mode Exit fullscreen mode

Put some templates to check into templates/ directories

$ mkdir templates/
Enter fullscreen mode Exit fullscreen mode

Run check

$ tom jinja-lint
