# nuwiki

**A vimwiki-compatible Vim/Neovim plugin backed by a Rust language server.**

nuwiki replaces the original [vimwiki](https://github.com/vimwiki/vimwiki)
plugin while keeping its file format, keymaps, and `:Vimwiki*` command
surface intact. The substantive work happens in a Rust LSP daemon — Vim
and Neovim are thin client layers that wire up keystrokes and display
results.

## Features

### Syntax & rendering

- Full vimwiki syntax (`.wiki`) — headings, lists with checkboxes,
  numbered / lettered / Roman lists, tables (with `|---|`, `|:--|--:|:--:|`
  alignment markers and `>` / `\/` colspan/rowspan), inline math, code
  fences, tags, comments, and links (wiki, interwiki, diary, file, local,
  raw URL, transclusion).
- Transclusions support attributes: `{{image.png|alt|style="border:1px"}}`.
- HTML export with templates, CSS, RSS feed, and incremental
  `:VimwikiAll2HTML`.

### Editor intelligence (LSP)

- Goto-definition (follow wikilinks), backlinks, hover preview,
  completion on `[[`, document outline, workspace symbol search.
- Semantic-token highlighting (no syntax-file fallback needed). Code fences
  tagged with a language (`{{{python … }}}`) get that language's syntax
  automatically — no `nested_syntaxes` config needed.
- Broken-link diagnostics and an orphan-page finder.
- Folding: server-driven `foldingRange` by default, regex fallback when
  the server isn't ready.

### Editing

- Insert-mode smart `<CR>`: continues list markers (`-`, `*`, `1.`,
  `a)`, `i)`, …) and checkboxes; breaks out of an empty bullet; inserts
  a fresh row when inside a `|…|` table.
- Insert-mode `<Tab>` / `<S-Tab>` jumps between table cells, adding a
  new row past the last column.
- `<C-D>` / `<C-T>` indent/dedent the current list item; `<C-L><C-J>`
  / `<C-L><C-K>` cycle through the marker styles; `<C-L><C-M>` toggles
  or adds a checkbox.
- Five text-object pairs in operator-pending + visual mode:
  `ah`/`ih` (heading section), `aH`/`iH` (heading + subtree),
  `al`/`il` (list item), `a\`/`i\` (table cell), `ac`/`ic` (table column).
- Two-step `<CR>` on a bare word: wraps it as `[[word]]`, second press
  follows the link.

### Diary

- Daily diary out of the box (`<Leader>w<Leader>w`, `<C-Down>` / `<C-Up>`).
- Configurable cadence: set `diary_frequency = 'weekly'` (or `'monthly'`
  / `'yearly'`) per wiki and the commands address
  `2026-W19.wiki` / `2026-05.wiki` / `2026.wiki` instead. Navigation
  stays at the same cadence as the entry under the cursor.
- Diary index page generation (`:VimwikiDiaryGenerateLinks`).

### Other

- Multi-wiki with cross-wiki `[[wn.name:Page]]` interwiki links and a
  `:VimwikiUISelect` picker.
- TOC generation, tag search, tag-to-page link lists.
- `:Vimwiki*` command compat + canonical `:Nuwiki*` aliases.
- Plain Vim and Neovim both supported with feature parity (text
  objects, folding, smart insert-mode bindings).

## Installation

The plugin ships a `nuwiki-ls` binary that the editor talks to over LSP
stdio. The `install()` helper downloads a pre-built release for your
platform, falling back to `cargo build --release` if no asset matches.
You can run it any time with `:NuwikiInstall` (works in both Vim and
Neovim) instead of relying on a plugin-manager build hook.

### Requirements

- **Neovim 0.11+** — uses the built-in LSP client; no extra plugin.
  Older releases fall back to a `vim.lsp.start` autocmd but aren't
  officially supported.
- **Vim 9+** — needs a third-party LSP client:
  [`vim-lsp`](https://github.com/prabirshrestha/vim-lsp) or
  [`coc.nvim`](https://github.com/neoclide/coc.nvim) — both
  auto-registered, no manual config (see [Vim LSP client
  setup](#vim-lsp-client-setup)).
- **Rust toolchain (1.83+ stable)** — only needed when building the
  binary from source; pre-built release downloads skip this.

### lazy.nvim

```lua
{
  'gffranco/nuwiki',
  build = ":lua require('nuwiki').install()",
  ft = { 'vimwiki' },
  opts = {
    wiki_root = '~/vimwiki',
  },
}
```

### vim-plug

```vim
Plug 'gffranco/nuwiki', { 'do': 'vim -e -s -c "source scripts/download_bin.vim" -c "q"' }
```

In `init.lua` / `init.vim`:

```lua
require('nuwiki').setup({ wiki_root = '~/vimwiki' })
```

### Dein

```vim
call dein#add('gffranco/nuwiki', {
  \ 'build': 'vim -e -s -c "source scripts/download_bin.vim" -c "q"'
  \ })
```

### Plain Vim (no plugin manager)

```sh
git clone https://code.gfran.co/gffranco/nuwiki ~/.vim/pack/gffranco/start/nuwiki
cd ~/.vim/pack/gffranco/start/nuwiki && cargo build --release -p nuwiki-ls
mkdir -p bin && cp target/release/nuwiki-ls bin/
```

### Vim LSP client setup

Neovim 0.11+ registers the server through its built-in LSP client
automatically — nothing to configure. Plain Vim needs one of the
following clients on its `runtimepath`; nuwiki picks them up in this
order when the first `.wiki` buffer loads.

**vim-lsp (recommended)** — zero configuration. Once
[`vim-lsp`](https://github.com/prabirshrestha/vim-lsp) (and its
[`async.vim`](https://github.com/prabirshrestha/async.vim) dependency)
is installed, nuwiki calls `lsp#register_server()` for you and vim-lsp
auto-enables it. Your wiki settings (`g:nuwiki_wiki_root`,
`g:nuwiki_wikis`, …) are forwarded as the server's initialization
options.

**coc.nvim** — also zero configuration. nuwiki registers itself with
[`coc.nvim`](https://github.com/neoclide/coc.nvim) programmatically
(`coc#config('languageserver.nuwiki', …)`) when the first `.wiki` buffer
loads, forwarding the same wiki settings (`g:nuwiki_wiki_root`,
`g:nuwiki_wikis`, your `g:vimwiki_*` config, the global shorthand, …) as
the server's initialization options. **No `coc-settings.json`
`languageserver` entry needed** — change your wiki config and reload; the
new settings are picked up.

To manage the entry yourself instead, set `let g:nuwiki_no_coc_register = 1`
and add it to `coc-settings.json` manually (nuwiki then just prints the
snippet on first load):

```json
{
  "languageserver": {
    "nuwiki": {
      "command": "~/.vim/pack/gffranco/start/nuwiki/bin/nuwiki-ls",
      "filetypes": ["vimwiki"],
      "initializationOptions": {
        "wiki_root": "~/vimwiki",
        "file_extension": ".wiki",
        "syntax": "vimwiki"
      }
    }
  }
}
```

Point `command` at the installed binary — by default it lives in the
plugin's `bin/` directory (adjust the path for your plugin manager), or
set `g:nuwiki_binary_path` and reuse that value.

`initializationOptions` is **required** — it carries `wiki_root` (and the
other [config keys](#configuration)) to the server, exactly as the vim-lsp
registration does automatically. Without it the server resolves links
against its default root, so existing pages show up as broken links and
following a link to a new page creates it in the wrong directory. (Run
`:NuwikiInstall`-time guidance, or `:call nuwiki#lsp#start()` once, to have
nuwiki print this snippet with your configured paths already filled in.)
With coc you can also invoke server commands directly via
`:CocCommand nuwiki.<command>` instead of the `:Vimwiki*` / `:Nuwiki*`
aliases.

### Try it without touching your config

```sh
./development/start-nvim.sh   # spawns Neovim against an isolated sample wiki
./development/start-vim.sh    # same, for plain Vim (clones vim-lsp on first run)
```

Both scripts build the LSP binary, seed a scratch wiki, and launch the
editor against an isolated state dir under `$XDG_CACHE_HOME/nuwiki-dev`.

## Configuration

Defaults are vimwiki-compatible. Every key has a sensible default — the
example below shows the full surface for reference.

```lua
require('nuwiki').setup({
  -- Single-wiki shorthand (vimwiki-compatible).
  wiki_root      = '~/vimwiki',
  file_extension = '.wiki',
  syntax         = 'vimwiki',     -- 'vimwiki' | 'markdown' (future)
  log_level      = 'warn',

  -- Multi-wiki: each entry honours every per-wiki key vimwiki understands.
  -- Pick either this OR the single-wiki shorthand above. If both are set,
  -- `wikis` wins.
  wikis = {
    {
      name             = 'personal',
      root             = '~/vimwiki',
      index            = 'index',        -- index page stem
      file_extension   = '.wiki',
      -- Diary
      diary_rel_path   = 'diary',
      diary_index      = 'diary',
      diary_frequency  = 'daily',        -- 'daily' | 'weekly' | 'monthly' | 'yearly'
      diary_weekly_style = 'iso',        -- 'iso' (YYYY-Www) | 'date' (week-start YYYY-MM-DD, vimwiki)
      diary_start_week_day = 'monday',   -- week start for diary_weekly_style='date'
      diary_sort       = 'desc',         -- 'desc' | 'asc'
      diary_header     = 'Diary',
      -- HTML export
      html_path        = '~/vimwiki/_html',
      template_path    = '~/vimwiki/_templates',
      template_default = 'default',
      template_ext     = '.tpl',
      css_name         = 'style.css',
      custom_wiki2html = '',             -- external converter; empty = built-in renderer
      custom_wiki2html_args = '',        -- extra args appended to the converter call
      base_url         = '',             -- public URL prefix for RSS item links
      auto_export      = false,          -- export on save
      auto_toc         = false,          -- auto-refresh TOC on save
      auto_generate_links = false,       -- regen Generated Links on save
      auto_generate_tags  = false,       -- regen Generated Tags index on save
      auto_diary_index    = false,       -- regen diary index on diary-entry save
      toc_header       = 'Contents',     -- :VimwikiTOC caption (+ toc_header_level = 1)
      links_header     = 'Generated Links',
      tags_header      = 'Generated Tags',
      exclude_files    = {},             -- glob patterns
      -- Checkbox progression characters: " .oOX" by default.
      listsyms         = ' .oOX',
      listsym_rejected = '-',           -- glyph for a cancelled checkbox [-]
      listsyms_propagate = true,
    },
  },

  -- Keymap groups. Flip subgroups off independently. Defaults all on.
  mappings = {
    enabled       = true,
    wiki_prefix   = true,  -- <Leader>w{w,t,s,i}, <Leader>w<Leader>{w,y,t,m,i}
    links         = true,  -- <CR>, <S-CR>, <C-CR>, <C-S-CR>, <D-CR>, <M-CR>, <BS>, <Tab>, <S-Tab>, + (n/x), <Leader>w{n,d,r}, <Leader>wc (n/x)
    lists         = true,  -- <C-Space>, gnt, gln, glp, glx, glh, gll, gLh, gLl (aliases gLH/gLL), glr, gLr (alias gLR), gl{-,*,#,1,i,I,a,A}, gL{…}, gl, gL, o, O; insert <C-D>, <C-T>, <C-L><C-J/K/M>, <CR>
    headers       = true,  -- =, -, ]], [[, ]=, [=, ]u, [u
    table_editing = true,  -- gqq, gq1, gww, gw1, <A-Left>, <A-Right>; insert <Tab>, <S-Tab>
    diary         = true,  -- <C-Down>, <C-Up>
    html_export   = true,  -- <Leader>wh, <Leader>whh, <Leader>wha
    text_objects  = true,  -- ah, ih, aH, iH, al, il, a\, i\, ac, ic
    mouse         = false, -- <2-LeftMouse>, <S-2-LeftMouse>, <C-2-LeftMouse>, <MiddleMouse>, <RightMouse> (opt-in)
  },

  -- 'lsp' (server-driven foldingRange, default) | 'expr' (regex) | 'off'.
  folding = 'lsp',

  -- Mirror Vim's &autowriteall while in a wiki buffer (auto-save on switch).
  autowriteall = true,
  -- Re-align the table under the cursor on InsertLeave.
  table_auto_fmt = true,

  -- Broken-link diagnostic severity: 'off' | 'hint' | 'warn' | 'error'.
  diagnostic = {
    link_severity = 'warn',
  },
})
```

Vim users without Lua set the equivalent globals before loading the
plugin:

```vim
let g:nuwiki_wiki_root            = '~/vimwiki'
let g:nuwiki_file_extension       = '.wiki'
let g:nuwiki_log_level            = 'warn'
let g:nuwiki_link_severity        = 'warn' " 'off'|'hint'|'warn'|'error'
let g:nuwiki_no_default_mappings  = 0   " set to 1 to skip the keymap layer
let g:nuwiki_map_prefix           = '<Leader>w'  " wiki command prefix
let g:nuwiki_no_folding           = 0   " set to 1 to skip foldexpr setup
let g:nuwiki_autowriteall         = 1   " set to 0 to not touch &autowriteall
let g:nuwiki_table_auto_fmt       = 1   " set to 0 to skip InsertLeave table re-align
let g:nuwiki_mouse_mappings       = 0   " set to 1 to enable mouse maps
" Drop individual keymap subgroups (mirror the Lua `mappings.<group>` toggles):
" g:nuwiki_no_{wiki_prefix,links,lists,headers,table_editing,diary,html_export,text_objects}_mappings
```

#### `mappings` subgroups

Each is a boolean. All default to `true` except `mouse`.

The `<Leader>w` prefix in the `wiki_prefix`, `links`, and `html_export` rows is the default `map_prefix` and moves with it.

#### Per-wiki keys (`wikis[]`)

Most display/generation keys below can also be set **once at the top level**
as a default for every wiki (vimwiki-style global shorthand) — via `setup({ … })`
or `g:nuwiki_<key>` — and a per-wiki value overrides it. The keys that honour
this are `toc_header`, `toc_header_level`, `toc_link_format`, `links_header`,
`links_header_level`, `tags_header`, `tags_header_level`,
`html_header_numbering`, `html_header_numbering_sym`, `links_space_char`,
`list_margin`, `listsyms`, `listsym_rejected`, and the `auto_*` toggles.

#### Vim globals (`g:nuwiki_*`)

For users configuring without Lua.

| Global | Default | Meaning |
|--------|---------|---------|
| `g:nuwiki_wiki_root` | `'~/vimwiki'` | single-wiki root |
| `g:nuwiki_file_extension` | `'.wiki'` | wiki file extension |
| `g:nuwiki_syntax` | `'vimwiki'` | wiki syntax |

## Usage

### Commands

`:Nuwiki*` is the canonical native surface; every command also has a
`:Vimwiki*` counterpart for drop-in migration. Both are registered as
buffer-local commands on every `.wiki` buffer (the wiki picker is also
global so you can switch wikis before any `.wiki` file is open). Type
`:Nuwiki<Tab>` or `:Vimwiki<Tab>` to browse them; coc.nvim users can
also call the server directly with `:CocCommand nuwiki.<command>`.

Only the legacy short forms `:VWB` / `:VWS` and `:VimwikiSearch` keep a
Vimwiki-only name (shown as `—` in the Nuwiki column); every other
command is mirrored. The split / tab link-following commands are
available on both the Neovim and plain-Vim paths.

### Default keymaps

All buffer-local. Disable the whole layer via `mappings.enabled = false` in
Neovim, or `let g:nuwiki_no_default_mappings = 1` in Vim. Drop a single group
via `mappings.<group> = false` in Neovim, or
`let g:nuwiki_no_<group>_mappings = 1` in Vim.

**Links** (normal mode)

| Key | Action |
|---|---|
| `<CR>` | Smart follow — inside `[[…]]` jumps; on a bare word wraps as `[[word]]` (second `<CR>` follows) |
| `<S-CR>` | Follow in horizontal split |
| `<C-CR>` | Follow in vertical split |
| `<C-S-CR>` / `<D-CR>` | Follow in a tab, reusing an existing tab if the file is already open (`<D-CR>` is the macOS Cmd alias) |
| `<M-CR>` | Add the link target to the buffer list (`:badd`, no jump) |
| `<BS>` | Jump back (`<C-o>`) |
| `<Tab>` / `<S-Tab>` | Next / previous wikilink on or after the cursor |
| `+` | Wrap word / visual selection as a wikilink (no follow) |

**Lists** (normal mode)

| Key | Action |
|---|---|
| `<C-Space>` / `<C-@>` / `<Nul>` | Toggle the checkbox under the cursor (the three aliases cover terminal byte differences) |
| `gln` / `glp` | Cycle the checkbox state forward / backward |
| `glx` | Toggle the rejected marker `[-]` |
| `gnt` | Jump to the next unfinished task |
| `glh` / `gll` | Dedent / indent the current list item |
| `gLh` / `gLl` | Dedent / indent including the item's sublist |
| `glr` | Renumber the current ordered list |
| `gLr` | Renumber every ordered list in the buffer |
| `gl<sym>` | Set the current item's marker to `<sym>` — one of `-` `*` `#` `1` (`1.`) `i` (`i)`) `I` (`I)`) `a` (`a)`) `A` (`A)`) |
| `gL<sym>` | Set every item in the list to `<sym>` (same symbol keys) |
| `gl` | Remove the checkbox from the current item, keeping its text |
| `gL` | Remove the checkbox from every item in the current list |
| `o` / `O` | Open a new line and continue the list marker (preserves any checkbox) |

Bare `gl` / `gL` share the `gl…` prefix with the maps above, so (like upstream
vimwiki) they fire only after `'timeoutlen'`; type a suffix such as `gln` or
`gl*` quickly to reach the prefixed maps. Removing *done* items is command-only:
`:NuwikiRemoveDone` (current list) / `:NuwikiRemoveDone!` (whole buffer).

**Lists** (insert mode)

| Key | Action |
|---|---|
| `<CR>` | Continue the list with the same marker (preserves checkbox), or break out on an empty bullet |
| `<S-CR>` | Multiline list item continuation (no new marker) |
| `<C-D>` / `<C-T>` | Dedent / indent the current item |
| `<C-L><C-J>` / `<C-L><C-K>` | Cycle the marker style (`-` → `*` → `#` → `1.` → `1)` → `a)` → `A)` → `i)` → `I)`) |
| `<C-L><C-M>` | Toggle / add a checkbox on the current item |

**Headers**

| Key | Action |
|---|---|
| `=` / `-` | Increase / decrease the heading level |
| `]]` / `[[` | Next / previous heading (any level) |
| `]=` / `[=` | Next / previous sibling heading |
| `]u` / `[u` | Jump to the parent heading |

**Tables**

| Key | Action |
|---|---|
| `gqq` / `gq1` / `gww` / `gw1` | Align the table under the cursor |
| `<A-Left>` / `<A-Right>` | Move the column under the cursor left / right |
| `<Tab>` / `<S-Tab>` (insert) | Jump to the next / previous cell; `<Tab>` past the last cell inserts a fresh row |
| `<CR>` (insert) | Insert a fresh empty row below the current one |

**Wiki / diary / export** (normal mode)

The `<Leader>w` prefix below is the default `map_prefix` (`g:nuwiki_map_prefix`); change that option to relocate the whole family.

| Key | Action |
|---|---|
| `<Leader>ww` | Open the wiki index |
| `<Leader>wt` | Open the wiki index in a new tab |
| `<Leader>ws` | Pick a wiki |
| `<Leader>wi` | Open the diary index |
| `<Leader>w<Leader>w` / `<Leader>w<Leader>y` | Diary today / yesterday |
| `<Leader>w<Leader>t` | Diary today, in a new tab |
| `<Leader>w<Leader>m` | Diary tomorrow |
| `<Leader>w<Leader>i` | Rebuild the diary index page |
| `<Leader>wn` / `<Leader>wd` / `<Leader>wr` | Goto / delete / rename page |
| `<Leader>wh` / `<Leader>whh` | Export the current page to HTML / open in browser |
| `<Leader>wha` | Export every page |
| `<Leader>wc` | Wrap word (or visual selection) in a colour span |
| `<C-Down>` / `<C-Up>` | Next / previous diary entry |

**Mouse** (normal mode, opt-in via `mappings.mouse = true` / `let g:nuwiki_mouse_mappings = 1`)

| Key | Action |
|---|---|
| `<2-LeftMouse>` | Follow the link under the pointer |
| `<S-2-LeftMouse>` / `<C-2-LeftMouse>` | Follow in a horizontal / vertical split |
| `<MiddleMouse>` | Add the link target to the buffer list |
| `<RightMouse>` | Jump back (`<C-o>`) |

**Text objects** (operator-pending + visual)

| Object | Selection |
|---|---|
| `ah` / `ih` | The heading's section (`ih` excludes the heading line) |
| `aH` / `iH` | The heading's section plus every subheading underneath |
| `al` / `il` | The list item under the cursor (`il` excludes the marker / checkbox) |
| `a\` / `i\` | The table cell under the cursor (`i\` excludes the surrounding `\|`) |
| `ac` / `ic` | The table column under the cursor (`ic` excludes the header separator row) |

### Health check (Neovim)

```vim
:checkhealth nuwiki
```

Reports the binary path, the LSP client status, registered
`executeCommand` entries, whether `foldingRange` was negotiated, and
whether the configured HTML output directory is writable.

### Migrating from vimwiki

The file extension, syntax, command names, and default keymaps all
match vimwiki. To migrate:

1. Drop the original `vimwiki` plugin from your config.
2. Install nuwiki.
3. Keep your existing config, or point `wiki_root` / `wikis[i].root` at
   your directory.

**Existing `g:vimwiki_list` config works as-is (Vim & Neovim).** When you
haven't configured nuwiki natively (`g:nuwiki_wikis` / `setup()` / `g:nuwiki_*`),
both clients read your upstream `g:vimwiki_list` and `g:vimwiki_*` globals and
translate them: each wiki's `path`/`path_html`/`template_*`/`auto_export`
plus globals like `toc_header_level`, `html_header_numbering`,
`html_header_numbering_sym`, `links_space_char`, and `list_margin`.
Native config always takes precedence. (Settings nuwiki implements
differently — see [`known-issues.md`](./known-issues.md) — are ignored.)
On Neovim with lazy.nvim, swap the `vimwiki` plugin spec for nuwiki and
call `require('nuwiki').setup()` — your `vim.g.vimwiki_list` is picked up
unchanged.

Existing pages, diary entries, tags, and templates work without
modification. The first workspace scan after launch may show an empty
`:VimwikiCheckLinks` result until the background index completes;
subsequent runs are instant.

A few upstream options are implemented differently or not at all — by
design, since nuwiki is LSP-backed rather than pure VimL. See
[`known-issues.md`](./known-issues.md) for the full list of divergences.
