guihua Guihua: A Lua Gui and util library for nvim plugins

  • Provide floating windows
  • A modified wrapper for fzy
  • TextView, ListView, Preview etc

  • Listview listview

  • Listview with fzy finder listview

  • Neovim multigrid external buffer/terminal

multigrid

  • Neovim vim.ui.input and vim.ui.select patch

This cool screen shows an external terminal running lazygit and an external floating window running guihua listview

More screen shot please refer to Navigator.lua

Please refer to test file of how to use it

Lua OOP is powered by middleclass fzy is powered by romgrk fzy-lua-native with modified version of sorter/quicksort to sort list of tables

Install

Plugin has implementation of fzy with both ffi and native lua. If you like to try ffi please run make

Packer

 use {'ray-x/guihua.lua', run = 'cd lua/fzy && make'}

lazy.nvim

{
  'ray-x/guihua.lua',
  build = 'cd lua/fzy && make',
  lazy = true,
  init = function()
    local configured = false

    local function ensure_guihua()
      if configured then
        return
      end

      configured = true
      require('guihua').setup({})
    end

    vim.ui.select = function(...)
      ensure_guihua()
      return require('guihua.gui').select(...)
    end

    vim.ui.input = function(...)
      ensure_guihua()
      return require('guihua.gui').input(...)
    end
  end,
}

The lazy.nvim example above keeps guihua unloaded until the first vim.ui.select() or vim.ui.input() call, which avoids paying the UI startup cost during Neovim startup.

vim.ui.select() callers can attach preview content directly by adding preview to each item or by passing preview_item = function(item) return ... end. Guihua will turn that content into a preview window automatically.

Setup

local icons = {
  panel_icons = {
    section_separator = '─', -- '',
    line_num_left = ':', -- '',
    line_num_right = '', -- '',

    range_left = '', -- '',
    range_right = '',
    inner_node = '', -- '├○',
    folded = '◉',
    unfolded = '○',

    outer_node = '', -- '╰○',
    bracket_left = '', -- '⟪',
    bracket_right = '', -- '⟫',
  },
  syntax_icons = {
    var = ' ', -- "👹", -- Vampire
    method = 'ƒ ', -- "🍔", -- mac
    ['function'] = ' ', -- "🤣", -- Fun
    ['arrow_function'] = ' ', -- "🤣", -- Fun
    parameter = '', -- Pi
    associated = '🤝',
    namespace = '🚀',
    type = ' ',
    field = '🏈',
    interface = '',
    module = '📦',
    flag = '🎏',
  },
}

require('guihua').setup({
  maps = {
    close_view = '<C-x>',
    send_qf = '<C-q>',
    save = '<C-s>',
    jump_to_list = '<C-w>k',
    jump_to_preview = '<C-w>j',
    prev = '<C-p>',
    next = '<C-n>',
    pageup = '<C-b>',
    pagedown = '<C-f>',
    confirm = '<C-o>',
    split = '<C-s>',
    vsplit = '<C-v>',
    tabnew = '<C-t>',
  },
  icons = icons,

  -- guihua disables strikethrough highlights inside its floating views to avoid accidental single-tilde (~) rendering (useful for paths like ~/foo).
})

Note: guihua disables the common strikethrough highlight groups for its floating views by default. You can control this behavior with setup options:

  • disable_strikethrough_in_views (default: true): when true, guihua disables common strikethrough highlight groups inside its floating views (no ~ or ~~ will show strike).
  • patch_markdown_strikethrough_query (default: false): when true, guihua will attempt to set a Treesitter highlights query so only explicit strikethrough nodes (usually produced for double-tilde) are linked to @markup.strikethrough. To test double-tilde-only behavior set disable_strikethrough_in_views=false and patch_markdown_strikethrough_query=true in your setup.
  • Long or multiline input prompts are rendered inside the same input popup, with a vertical split glyph separating the prompt text area from the editable input line.
  • vim.ui.input() uses a window title for short prompts: explicit title wins, otherwise the first prompt line is used; long or multiline prompts render inside the popup body instead of being clipped in the title bar.
  • Diff previews are available via require('guihua.gui').diffview({ title = ..., description = ..., diff = ..., syntax = ... }).
  • Diff previews support close_keymap and autoclose = 'InsertLeave' (or { events = { 'WinLeave' }, timeout = 5000 }).
  • diffview() opts:
    • title: border title.
    • description: rendered before the diff body.
    • diff: unified diff text.
    • syntax: optional syntax for the diff body.
    • close_keymap: buffer-local close key, default <C-c>.
    • autoclose: event name, event list, or { events = {...}, timeout = ms }.
    • autoclose_focus_moved: shorthand for WinLeave/BufLeave.

Example:

require('guihua').setup({ disable_strikethrough_in_views = false, -- allow strikethrough in guihua views patch_markdown_strikethrough_query = true, -- make Treesitter highlight only double-tilde as strikethrough })

guihua.gui.catalog() adds a tabbed floating browser for TOC-style data. It keeps the @markup.strikethrough override local to guihua popups and opens the selected path on Enter by default. Use <Left> / <Right> to move between tabs.

Catalog options:

  • tabs: keyed table ({ agents = {...}, skills = {...} }) or list form ({ { key = 'agents', items = {...} } })
  • tab_order/order: explicit order for keyed tabs
  • loc: list placement (default top_center)
  • rect or width/height: list size (default height auto-fits item count)
  • list_height_ratio: max list height ratio (default 0.45)
  • preview_height_ratio: preview height ratio (default 0.4)
  • on_confirm(item, active_tab): callback when confirming a selection
require('guihua.gui').catalog({
  title = 'Browse',
  tabs = {
    agents = {
      { name = 'grep', description = { 'this is a grep agent' }, path = '/path/to/agent.lua' },
    },
    skills = {
      { name = 'lint', description = 'this is a lint skill', path = '/path/to/skill.lua' },
    },
  },
  tab_order = { 'agents', 'skills' },
})

Plug

Plug 'ray-x/guihua.lua', {'do': 'cd lua/fzy && make' }

Usage: check the test files on how the api is used.

Git commit agent

This repository includes a repo-local commit helper at scripts/git_commit_agent.py.

It will:

  • use the current staged diff, or stage everything with --all
  • run the repo sanity checks before committing
  • block the commit if selene lua or make tests fails
  • generate a conventional-style commit message from the staged changes
  • optionally push the commit to GitHub or GitLab remotes with --push

Examples:

python3 scripts/git_commit_agent.py --dry-run
python3 scripts/git_commit_agent.py --all
python3 scripts/git_commit_agent.py --all --push
