🚀 Usage

Configuration

exercism.setup({
    exercism_workspace = '~/exercism', -- Default workspace for exercism exercises
    default_language = 'ruby', -- Default language for exercise list
    add_default_keybindings = true, -- Whether to add default keybindings
    max_recents = 30, -- Maximum number of recent exercises to keep
    icons = {
        concept = '', -- Icon for concept exercises
        practice = '', -- Icon for practice exercises
    },
})

Commands

exercism.nvim provides a unified command interface with tab completion:

• Exercism languages - Lists all available languages, select one to list exercises
• Exercism list [language] - Lists exercises for the specified language, show exercises for default language if not specified
• Exercism test - Runs tests for the current exercise
• Exercism submit - Submits the current exercise
• Exercism open <language> <exercise> - Opens a specific exercise directly in the specified language
• Exercism exercise <exercise> - Opens a specific exercise directly using the default language
• Exercism recents - Shows recently opened exercises in a fuzzy searchable list

⛅ Behind The Code

🌈 Inspiration

I really like exercism but the back and forth between the browser and the terminal was a bit annoying. So I decided to integrate it with Neovim.

💡 Challenges/Learnings

• I build exercism-fetcher to fetch exercises from exercism's github repos.
• Reused knowledge from octohub.nvim, not too many challenges here.
