gem_install.nvim

Install Ruby gems from Neovim! Handles bundle install and gem install with progress notifications and caching to prevent retries when installs fail. Useful for LSP servers and other tools that depend on gems being available.

Features

• Runs bundle check before attempting installs
• Runs bundle install if needed (with configurable timeout)
• Installs gems via gem install if not already present
• Caches failures per-project to avoid repeated attempts
• Shows progress via fidget.nvim
• Logs all output for debugging

Dependencies

• fidget.nvim (for progress UI)

Installation

Using lazy.nvim:

{
    "cosmicbuffalo/gem_install.nvim",
    opts = {},
    dependencies = { "j-hui/fidget.nvim" },
}

Usage

require("gem_install").install("ruby-lsp")

Configuration

-- Optional, below are built in defaults
require("gem_install").setup({
    -- Timeout for bundle install in milliseconds
    bundle_install_timeout = 60000,
    -- Cache file for tracking failed installs
    cache_file = vim.fn.stdpath("cache") .. "/bundle_install_cache.json",
    -- Log file for debug output
    log_file = vim.fn.stdpath("log") .. "/bundle_gem_debug.log",
})

Commands

Caveats

• Requires a Gemfile in the current directory or a parent directory. The plugin will show a warning if no Gemfile is found.
• Once a project fails bundle install, it won't retry automatically. Use :GemInstallCacheClear to reset and try again.
• bundle install has a 60 second timeout by default (configurable via bundle_install_timeout).
