TUI Keymaps

| Key | Action | |-----|--------| | I | Install mode (button highlight) | | U | Update all installed packages (max 3 concurrent) | | C | Check for remote updates (git ls-remote commit compare) |

| H | Home (reset all state) | | ? | Help | | i | Install package under cursor | | u | Update package under cursor | | X | Uninstall package under cursor | | R | Reinstall package under cursor | | f | Cycle filter: all → installed → available | | s | Cycle sort: default → name → status → type | | j / k | Scroll through packages (virtual scroll) | | gg | Jump to first package | | G | Jump to last package | | <CR> | Open detail popup (info / install log with syntax highlights) | | / | Search filter | | q | Close (auto :CocRestart if changes detected) | | <Esc> | Language filter→Search→Close |

Commands

| Command | Action | |---------|--------| | :CocCommand loader.open | Open TUI | | :CocCommand loader.install <name> | Install a package | | :CocCommand loader.uninstall <name> | Uninstall a package | | :CocCommand loader.update <name> | Update a package | | :CocCommand loader.reinstall <name> | Reinstall a package (uninstall + install) | | :CocCommand loader.uninstallAll | Uninstall all (with confirmation) | | :CocCommand loader.updateRegistry | Fetch latest registry from remote | | :CocCommand loader.cleanCache | Clean build cache for all packages | | :CocCommand loader.list | List installed packages (copied to clipboard) |

Global Extensions (auto-install)

Define extensions to auto-install on plugin activation via vim variable:

" .vimrc
let g:coc_loader_global_extensions = ['vscode-pyright', 'vscode-eslint', 'vscode-lua']

-- init.lua
vim.g.coc_loader_global_extensions = { 'vscode-pyright', 'vscode-eslint', 'vscode-lua' }

On next :CocRestart, the plugin will fetch the registry and install any missing extensions concurrently (max 3 at a time). Installed extensions are skipped.

Features

• Real conversion pipeline — git clone → converter → npm install → esbuild → register to coc
• Source-compiled servers — pipeline auto-installs Go servers via go install (goPackages) and Rust servers via cargo install (cargoPackages), binaries go to server/ directory
• Binary server download — auto-downloads pre-built server binaries from GitHub Releases (.zip, .tar.gz, .gz)
• Local server build — auto-copies server/ directory from source, installs deps, compiles TypeScript during build
• Pip install — auto-installs Python packages via pip for plugins that need them (e.g. ansible-lint)
• Auto-fetch registry — remote registry fetched in background when TUI opens, no manual refresh needed
• Virtual scrolling — j/k smooth scroll through packages, handles 100k+ registry entries
• Incremental cache — source/ keeps git repo, updates via git pull only
• Commit tracking — records commit SHA after install, visible in detail view
• Update check — C key compares against remote HEAD, shows ↑ when outdated
• Auto restart — :CocRestart triggered automatically on close when changes detected
• Manual registry update — :CocCommand loader.updateRegistry also available for re-fetch
• Detail popup — <CR> opens centered float window with package info or live install log (syntax highlighted, auto-scroll to latest)
• Filter & sort — f cycle view filter, s cycle sort order (name/status/type)
• Concurrency limit — max 3 parallel operations for U (Update All)
• Desktop notifications — showInformationMessage on install/update/uninstall complete
• Auto-check updates — silent check on startup, notifies only when updates found
• Cache cleanup — :CocCommand loader.cleanCache removes build artifacts
• Export package list — :CocCommand loader.list copies installed package names to clipboard

Architecture

| File | Description | |------|-------------| | src/index.ts | Plugin entry + 8 CocCommands | | src/tui.ts | TUI window management + rendering + key dispatch | | src/state.ts | State management (debounced rendering) | | src/registry.ts | Remote registry fetch + disk cache | | src/pipeline.ts | Real install/update/uninstall flow (git + npx tsx + npm + node + cp). Handles local servers (copies server/ dir, installs deps), binary server download, Go/Cargo source-compiled servers, pip install. | | src/renderer.ts | LineBuffer render engine (inspired by lazy.nvim) |

Build

npm install
npm run build    # esbuild → lib/index.js
