Q: What are the default keybinds for arena.nvim?

Default keybinds include ` ` to open, 'd' to delete, 'D' to delete all unpinned, 'p' to pin, and ` `, ` `, ` ` for splits and tabs. These are customizable in the keybinds config, but the README warns that unsetting them requires setting values to `nil`.

Question 1

How does arena.nvim compare to telescope.nvim for switching buffers?

Accepted Answer

arena.nvim focuses on frecency-based sorting without search, ideal for habitual file switches based on usage, while telescope.nvim offers powerful fuzzy finding and extensibility but doesn't prioritize by usage automatically. For quick access to frequently used files, arena.nvim is faster, but for searching across projects, telescope is better.

Question 2

How to set up arena.nvim with lazy.nvim?

Accepted Answer

Add the plugin to your lazy.nvim config with `event = "BufWinEnter"` and `config = true` to auto-setup, or manually call `require("arena").setup()` in the config function. Ensure the plugin is installed and restart Neovim, as per the README's getting started section.

Question 3

Can I use arena.nvim without nvim-web-devicons?

Accepted Answer

Yes, devicons are optional and disabled by default. If you don't have nvim-web-devicons installed, leave `devicons = false` in the config, and the arena window will display without icons, as mentioned in the configuration options.

Question 4

How to pin a buffer in arena.nvim?

Accepted Answer

In the arena window, press 'p' on the buffer line to pin it, keeping it at the top. You can also use the Lua API `require("arena").pin(bufnr)` for programmatic pinning, as documented in the API section of the README.

Question 5

Does arena.nvim support per-project buffer filtering?

Accepted Answer

Yes, enable `per_project = true` in the config to filter buffers based on the current project. This helps in multi-project environments by showing only relevant files, but it requires proper project detection setup, which isn't detailed in the README.

Question 6

What are the default keybinds for arena.nvim?

Accepted Answer

Default keybinds include `` to open, 'd' to delete, 'D' to delete all unpinned, 'p' to pin, and ``, ``, `` for splits and tabs. These are customizable in the keybinds config, but the README warns that unsetting them requires setting values to `nil`.

Question 7

How to adjust the frecency algorithm in arena.nvim?

Accepted Answer

In the config, under the `algorithm` table, set `recency_factor` and `frequency_factor` to balance sorting—lower recency_factor reduces emphasis on recent use. The README provides default values but offers no guidance on optimal tuning for different workflows.
