# muwiki.nvim
A lightweight wiki plugin for Neovim using standard markdown syntax.
## Requirements
- Neovim v0.10+
- Treesitter markdown parsers (`:TSInstall markdown markdown_inline`)
## Features
- Standard markdown links `[text](url)`
- Multiple wiki directories
- External link handlers
- Automatic template for new page
- Link navigation with custom keymaps
See `:help muwiki` for complete documentation and configuration options.
## Installation
Using [lazy.nvim](https://github.com/folke/lazy.nvim):
```lua
{
url = "https://git.3kgcat.fi/muwiki.nvim",
keys = {
{ "<leader>ww", function() require("muwiki").open_index("default") end, desc = "Open wiki index" },
},
opts = {
-- Wiki directories (REQUIRED - configure at least one)
dirs = {{ name = 'default', path = '~/wiki' }},
},
-- autogroup only loads keymaps in wiki files
config = function(_, opts)
local muwiki = require('muwiki')
muwiki.setup(opts)
local group = vim.api.nvim_create_augroup("MuWikiKeymaps", { clear = true })
vim.api.nvim_create_autocmd("FileType", {
group = group,
pattern = "markdown",
callback = function(ev)
if not muwiki.wiki_root(ev.buf) then return end
local keymap_opts = { buffer = ev.buf, silent = true, nowait = true }
vim.keymap.set('n', '<CR>', muwiki.open_link, keymap_opts)
vim.keymap.set('n', '<Tab>', muwiki.next_link, keymap_opts)
vim.keymap.set('n', '<S-Tab>', muwiki.prev_link, keymap_opts)
vim.keymap.set('v', '<CR>', muwiki.create_link, keymap_opts)
vim.keymap.set('n', '<leader>oo', muwiki.open_link_with, keymap_opts)
end,
})
end,
}
```
**Available actions:**
- `open_link()` - Open link under cursor
- `next_link()` - Jump to next markdown link
- `prev_link()` - Jump to previous markdown link
- `create_link()` - Create link from visual selection
- `open_link_with()` - Open link with custom external handler
See `:help muwiki-commands` for complete API documentation.
## Link Format
```text
[Wiki page](page.md)
[Website](https://example.com)
[Relative path](file://../document.pdf)
[Absolute path](file:///tmp/image.png)
```
## External Handlers
Define custom handlers for opening external URLs and files:
```lua
external_handlers = {
-- Open HTTP/HTTPS URLs in Firefox
{
name = 'Firefox',
cmd = 'firefox',
pattern = '^https?://',
},
-- Open videos with mpv (local files and YouTube)
{
name = 'mpv',
cmd = 'mpv',
pattern = {
'%.mp4$',
'%.mkv$',
'%.avi$',
'%.webm$',
'youtube%.com',
'youtu%.be',
},
},
-- Open images with swayimg
{
name = 'swayimg',
cmd = 'swayimg',
pattern = {
'%.png$',
'%.jpe?g$',
'%.gif$',
'%.webp$',
'%.bmp$',
},
},
-- Copy URL to clipboard using wl-copy
{
name = 'Copy URL',
cmd = function(url)
vim.system({ 'wl-copy', url }, { detach = true })
vim.notify('URL copied to clipboard', vim.log.levels.INFO)
end,
pattern = '.*',
},
-- Fallback for any URL (Linux)
{
name = 'xdg-open',
cmd = 'xdg-open',
pattern = '.*',
},
}
```
**Handler properties:**
- `name` - Display name in the handler menu
- `cmd` - Command string or Lua function
- `pattern` - Lua pattern(s) to match URLs (string or table of strings; optional, matches all if omitted)
**Note:** Files with extensions in `text_extensions` will always open in Neovim, bypassing external handlers.
