Small Elixir app that checks all files in a directory for missing metadata to practice the Elixir lang.

1. Clone repo

2. cd blog_linter

3. Download any dependency with:

$ mix deps.get

4. Run the main script with:

$ mix run main.ex
["post1.markdown", "post2.markdown"]

• For each file:
  • check all meta data in the --- yaml --- section
  • check the <!-- more --> comment is present
  • validate that the post metadata image file actually exists
• Process all files:
• Return failures

• Add linting for the code editor using Credo
• Add the elixir language server extension for your code editor
