nuwiki — Project Specification

Last updated: 2026-05-11 Status: v1.0 (Phases 0–10) shipped; v1.1 (Phases 11–18) in design

Versioning convention

• v1.0 — the parsing + highlighting + navigation foundation. LSP server speaks the spec's §6.9 method set; editor glue provides install + setup
  • health check.
• v1.1 — full vimwiki replacement. Adds tags, diary, the text-manipulation command surface (toggle checkbox, change list symbol, format table, rename page, …), multi-wiki, HTML export commands, link-health diagnostics, and the keymap/text-object layer that matches vimwiki's daily-authoring ergonomics.

---

1. Overview

nuwiki is a Vim/Neovim plugin that provides full vimwiki syntax support, implemented as a Rust-based Language Server (LSP). It is a spiritual successor to vimwiki, architecturally distinct from it, designed for correctness, performance, and extensibility.

Goals:

• Full vimwiki syntax support (highlighting, navigation, link following, diagnostics)
• First-class support for both Vim 9+ and Neovim 0.5+
• Installable via standard plugin managers (lazy.nvim, vim-plug, Dein)
• Extensible to Markdown syntax without changes to core architecture
• Independently testable core library with no editor dependencies

Non-goals (v1.0):

• MediaWiki syntax support
• Multi-wiki configurations (addressed in v1.1, see §12)
• Incremental / tree-sitter parsing
• Browser-based or WASM build

v1.1 scope (see §12 for the full plan):

• Vimwiki-parity command surface (:Vimwiki* compat aliases over LSP executeCommand)
• Tags, diary, link health, HTML export commands, multi-wiki, folding

4. Technology Stack

Concern	Choice	Rationale
Implementation language	Rust	Performance, type safety, single binary distribution, ideal for AST modelling
Editor integration	LSP over stdio	Works in both Vim and Neovim without a shared scripting language
LSP server library	tower-lsp	Async, tokio-based, higher-level than lsp-server; easier to start with
Parser library	None — hand-rolled recursive descent	Tokens are span-bearing structs that fit awkwardly into winnow/nom combinator style; resilience and error recovery are explicit in the parser code. Originally specified as winnow; revisited in Phase 4.
Cargo edition	2021	Current standard; required for resolver v2
Cargo resolver	v2	Required for edition 2021 workspaces
Vim glue layer	VimL (plugin/nuwiki.vim, autoload/)	Universal entry point for all plugin managers
Neovim glue layer	Lua (lua/nuwiki/)	First-class Neovim API access via vim.lsp.start()

6.2 Crate Dependency Rules

nuwiki-ls  →  nuwiki-lsp  →  nuwiki-core

• nuwiki-core must never depend on nuwiki-lsp or nuwiki-ls
• nuwiki-lsp must never depend on nuwiki-ls
• The VimL and Lua editor layers must never contain logic — pure wiring only

6.3 Syntax Plugin Interface

Every syntax (vimwiki, future markdown) implements:

SyntaxPlugin
  id:             string          -- "vimwiki" | "markdown"
  display_name:   string
  file_extensions: string[]       -- [".wiki"] | [".md"]
  lexer:          fn(text) → TokenStream
  parser:         fn(TokenStream) → DocumentNode

Registry:

SyntaxRegistry
  register(plugin: SyntaxPlugin)
  get(id: &str) → Option<&SyntaxPlugin>
  detect_from_extension(ext: &str) → Option<&SyntaxPlugin>

All plugins must be Send + Sync (held in the LSP server registry).

6.4 AST Node Types

Document

DocumentNode
  children:  Vec<BlockNode>
  metadata:  PageMetadata        -- title, nohtml, template, date

Block Nodes

HeadingNode        level: 1–6 | children: Vec<InlineNode> | centered: bool
ParagraphNode      children: Vec<InlineNode>
HorizontalRuleNode
BlockquoteNode     children: Vec<BlockNode>
PreformattedNode   content: String | language: Option<String>
MathBlockNode      content: String | environment: Option<String>
ListNode           ordered: bool | symbol: ListSymbol | items: Vec<ListItemNode>
DefinitionListNode items: Vec<DefinitionItemNode>
TableNode          rows: Vec<TableRowNode> | has_header: bool
CommentNode        content: String
ErrorNode          raw: String | message: String   -- resilient parse failure

Inline Nodes

TextNode           content: String
BoldNode           children: Vec<InlineNode>
ItalicNode         children: Vec<InlineNode>
BoldItalicNode     children: Vec<InlineNode>

CodeNode           content: String
SuperscriptNode    children: Vec<InlineNode>
SubscriptNode      children: Vec<InlineNode>
MathInlineNode     content: String
KeywordNode        keyword: Keyword  -- TODO|DONE|STARTED|FIXME|FIXED|XXX
ColorNode          color: String | children: Vec<InlineNode>
WikiLinkNode       target: LinkTarget | description: Option<Vec<InlineNode>>
ExternalLinkNode   url: String | description: Option<Vec<InlineNode>>
TransclusionNode   url: String | alt: Option<String> | attrs: HashMap<String,String>
RawUrlNode         url: String

Supporting Types

ListItemNode
  symbol:    ListSymbol
  level:     usize
  checkbox:  Option<CheckboxState>
  children:  Vec<InlineNode>
  sublist:   Option<ListNode>

DefinitionItemNode
  term:        Option<Vec<InlineNode>>
  definitions: Vec<Vec<InlineNode>>

TableRowNode   cells: Vec<TableCellNode> | is_header: bool
TableCellNode  children: Vec<InlineNode> | col_span: bool | row_span: bool

LinkTarget
  kind:         LinkKind   -- Wiki|Interwiki|Diary|File|Local|Raw|AnchorOnly
  path:         Option<String>
  wiki_index:   Option<usize>
  wiki_name:    Option<String>
  anchor:       Option<String>
  is_absolute:  bool
  is_directory: bool

ListSymbol    = Dash | Star | Hash | Numeric | NumericParen
              | AlphaParen | AlphaUpperParen | RomanParen | RomanUpperParen
CheckboxState = Empty | Quarter | Half | ThreeQuarters | Done | Rejected
Keyword       = Todo | Done | Started | Fixme | Fixed | Xxx

6.5 Span / Source Location

Every AST node carries a Span:

struct Span {
    start: Position,
    end:   Position,
}

struct Position {
    line:   u32,   -- 0-indexed
    column: u32,   -- 0-indexed, byte offset within line
    offset: usize, -- absolute byte offset from document start
}

Spans are required for LSP diagnostics, semantic tokens, and go-to-definition.

6.6 Lexer Strategy

• Two-pass: block-level pass first, then inline pass within each block
• Token types: syntax-specific (VimwikiToken) — not shared across syntaxes
• TokenStream: eager Vec<Token> wrapped in a TokenStream newtype (changeable to lazy later)
• Operates on Rust chars for correctness; spans stored as byte offsets

6.7 Parser Strategy

• Uses winnow parser combinator library
• Resilient: on malformed input, emits ErrorNode and continues — never fails the whole document
• Inline marker precedence rules documented explicitly in code and tests

6.8 Renderer

• Renderer trait: writer-based (fn render(&self, doc: &DocumentNode, w: &mut dyn Write))
• HtmlRenderer is the first implementation
• Link resolution injected as a callback at construction time
• Template support: minimal {{content}} / {{title}} token substitution
• CSS: linked external stylesheet (matches vimwiki convention)

6.9 LSP Features

Feature	LSP Method
Syntax highlighting	textDocument/semanticTokens/full + /range
Diagnostics (broken links, parse errors)	textDocument/publishDiagnostics
Follow link / go to definition	textDocument/definition
Backlinks	textDocument/references
TOC / outline	textDocument/documentSymbol
Link preview	textDocument/hover
Link autocomplete	textDocument/completion (trigger: [[)
Page rename	workspace/rename
Workspace search	workspace/symbol

6.10 Document Store

DocumentStore: Arc<DashMap<Url, DocumentState>>

DocumentState
  text:     String
  ast:      DocumentNode
  version:  i32

Full re-parse on every didOpen / didChange. Incremental parsing deferred post-v1.

6.11 UTF-16 / Position Encoding

LSP positions negotiated as UTF-8 (positionEncoding = "utf-8") during initialize where the client supports LSP 3.17+. UTF-16 conversion fallback implemented in the LSP layer for older clients. nuwiki-core is always UTF-8 / byte-offset internally.

7. Editor Integration

7.1 Plugin Manager Installation

lazy.nvim:

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

vim-plug:

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

Dein:

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

7.2 Binary Distribution

• Pre-built binaries published as Gitea release assets
• Named: nuwiki-ls-{version}-{target}.tar.gz
• Downloaded at install time by lua/nuwiki/install.lua or scripts/download_bin.vim
• Fallback: cargo build --release if download fails or g:nuwiki_build_from_source = 1
• Binary installed to {plugin_dir}/bin/nuwiki-ls[.exe]

7.3 Editor Detection

" plugin/nuwiki.vim
if has('nvim')
  lua require('nuwiki').setup()
else
  call nuwiki#lsp#start()
endif

7.4 Vim LSP Client Preference Order (Vim only)

1. vim-lsp (matoto/vim-lsp)
2. coc.nvim
3. Error message if neither found

7.5 User Config Schema

require('nuwiki').setup({
  wiki_root      = "~/vimwiki",   -- root directory of the wiki
  file_extension = ".wiki",       -- file extension to associate
  syntax         = "vimwiki",     -- "vimwiki" | "markdown" (future)
  log_level      = "warn",        -- "error"|"warn"|"info"|"debug"
})

7.6 Health Check

:checkhealth nuwiki verifies:

• Binary exists at {plugin_dir}/bin/nuwiki-ls
• Binary is executable and responds to --version
• LSP client is running
• Filetype detection works for .wiki files

---

8. CI/CD

8.1 Runner Setup

Property	Value
System	Gitea Actions (act_runner)
Mode	Docker (jobs run in containers)
Docker access	Host socket mounted (/var/run/docker.sock)
Internet access	Yes

8.2 Workflow Files

.gitea/workflows/ci.yaml — triggers on every push and PR:

11. Pending Decisions

These decisions are required before or during the phase indicated.

#	Decision	Needed by	Options	Notes
P1	License	Phase 0	✅ Dual MIT/Apache-2.0
P2	MSRV	Phase 0	✅ stable-2 (Rust 1.83)
P3	String representation in AST	Phase 1	✅ String (owned)
P4	Visitor pattern	Phase 1	✅ Defined in Phase 1	Open-recursion Visitor trait + walk_* helpers
P5	Minimum Neovim version	Phase 9	✅ Neovim 0.11+	Server registered via vim.lsp.config{} + vim.lsp.enable; a vim.lsp.start autocmd fallback is wired up but only fires when the declarative API is unavailable.
P6	Minimum Vim version	Phase 9	✅ Vim 9.1+	autoload glue assumes 9.1 idioms; uses vim-lsp first, then falls back to coc.nvim.
P7	Semantic token type mapping	Phase 7	✅ Custom vimwiki-specific token types	~20 types (vimwikiHeading, vimwikiBold, …) + level1..level6 + centered modifiers. Phase 9 ships default highlight groups in syntax/nuwiki.vim and the Lua glue.
P8	Workspace indexing strategy	Phase 8	✅ Lazy + background with progress	Initial scan runs as a background tokio task; nav features answer with partial data until complete; progress reported via window/workDoneProgress.
P9	macOS runner	Phase 10	✅ Stay manual	Release workflow cross-compiles the 4 Linux targets via cross; macOS + Windows binaries are produced ad hoc by maintainers and uploaded to the same Gitea release. Revisit when a Mac runner is available.
v1.1 decisions
P10	Command namespace	Phase 13	:Vimwiki* only · :Nuwiki* only · both	Both → easy migration and discoverable native commands; one canonical name + alias.
P11	Tag syntax	Phase 12	Strict vimwiki :tag: only · Add markdown #tag as a second flavour	Strict keeps parity; adding #tag collides with hash list markers and ordered-list #.
P12	List-edit transport	Phase 14	Server returns WorkspaceEdit from executeCommand · Editor-side text manipulation in VimL/Lua	WorkspaceEdit keeps logic in Rust + testable, but adds latency per keystroke for <C-Space>.
P13	Multi-wiki config shape	Phase 18	Lua list (Neovim-native) · JSON config file (cross-editor)	Lua is ergonomic for Neovim; JSON works for Vim + arbitrary clients.
P14	Folding mechanism	Phase 19	✅ LSP textDocument/foldingRange (primary) + foldexpr fallback	Server already has the AST + heading boundaries — duplicating that knowledge as regex in VimL would be lossy. foldexpr ships in ftplugin as a fallback for when the server hasn't attached.
P15	Diary path scheme	Phase 16	Fixed <wiki_root>/diary/ · Per-wiki configurable diary_rel_path	Vimwiki has diary_rel_path; matching keeps migrations clean.
P16	Backwards-compat for v1.0 config	Phase 18	Preserve old single-wiki_root shape · Force migration to wikis = [...]	Single-wiki should keep working without re-config; wiki_root becomes sugar for wikis = [{ root = wiki_root }].
P17	Markdown syntax in v1.1	Phase 12+	Include · Defer to v1.2	Architecture already supports it (SyntaxPlugin); cost is parser work + per-syntax differences in commands.
P18	Server-config transport	Phase 11	initializationOptions only · workspace/didChangeConfiguration only · both	Both → simple boot path and live reload. Initialise at startup, accept change notifications afterwards.

12. v1.1 — Full vimwiki Replacement

v1.0 shipped the parsing + highlighting + navigation foundation. A vimwiki user transitioning to nuwiki today gets accurate syntax recognition and modern LSP nav, but loses the dense interactive layer that makes vimwiki ergonomic for daily authoring: ≈40 :Vimwiki* commands, ≈60 keymaps, the diary, the tag system, link health, HTML export commands, and multi-wiki configuration.

v1.1 closes that gap. The architecture is unchanged — every new editing operation lands as an LSP executeCommand returning a WorkspaceEdit, so the nuwiki-core AST stays the single source of truth and the editor glue stays pure wiring.

12.1 Stability commitment

v1.1 is additive. The following stay backward-compatible:

• nuwiki-core public AST + Visitor (additions only; no field renames)
• LSP capabilities advertised in v1.0
• Renderer trait + HtmlRenderer default output shape
• v1.0 user-config keys (wiki_root, file_extension, syntax, log_level)

New AST nodes (e.g. TagNode) and new LSP capabilities are opt-in by inspection. The Visitor trait gains default-bodied visit_* methods for new node kinds so existing Visitor implementations don't break.

12.2 Plumbing prerequisites (Phase 11)

Cross-cutting infrastructure that every later v1.1 phase depends on. Landing it as Phase 11 — before any user-visible feature — keeps Phases 12–19 mechanical instead of full of "oh we also need to refactor X".

12.2.1 Server config receipt (P18)

Per P18: both initializationOptions and workspace/didChangeConfiguration land in Phase 11.

• initialize.initializationOptions carries the full v1.1 config (§12.11 schema) verbatim. Parsed into a server-side Config struct.
• workspace/didChangeConfiguration re-applies the config for live reload.
• Every handler reads from a single Arc<RwLock<Config>> field on Backend.

pub struct Config {
    pub log_level: LogLevel,
    pub diagnostic: DiagnosticConfig,
    pub wikis: Vec<WikiConfig>,        // always ≥ 1; v1.0-shape desugars
    // …
}

impl Config {
    pub fn from_init_options(value: serde_json::Value) -> Self;
    pub fn from_v1_0_compat(legacy: LegacyConfig) -> Self;  // P16 path
}

12.2.2 WorkspaceEditBuilder + span helpers

New module crates/nuwiki-lsp/src/edits.rs:

pub fn text_edit_replace(span: Span, replacement: String, text: &str, utf8: bool) -> TextEdit;
pub fn text_edit_insert(pos: Position, content: String) -> TextEdit;
pub fn text_edit_delete(span: Span, text: &str, utf8: bool) -> TextEdit;
pub fn op_rename(old: Url, new: Url) -> DocumentChangeOperation;
pub fn op_delete(uri: Url) -> DocumentChangeOperation;

pub struct WorkspaceEditBuilder {
    changes: HashMap<Url, Vec<TextEdit>>,
    file_ops: Vec<DocumentChangeOperation>,
}
impl WorkspaceEditBuilder {
    pub fn edit(&mut self, uri: Url, edit: TextEdit) -> &mut Self;
    pub fn file_op(&mut self, op: DocumentChangeOperation) -> &mut Self;
    pub fn build(self) -> WorkspaceEdit;
}

All v1.1 commands that produce WorkspaceEdit (Phases 13–17) go through the builder. Standardises UTF-8/UTF-16 conversion and document-change ordering.

12.2.3 Closed-doc loader

pub struct DocSnapshot {
    pub text: String,
    pub ast: DocumentNode,
    pub in_memory: bool,    // held in `documents` DashMap
}

impl Backend {
    pub async fn read_or_open(&self, uri: &Url) -> io::Result<DocSnapshot>;
}

If the URI is in documents, return live state. Otherwise read the file from disk and re-parse so cross-document operations (Phase 13 workspace/rename) can compute accurate spans + UTF-16 conversions instead of trusting stale WorkspaceIndex data.

12.2.4 Diagnostic source chain

Today's ast_diagnostics(&ast, &text, utf8) is replaced by a composable collector:

pub fn collect_diagnostics(
    ast: &DocumentNode,
    text: &str,
    index: Option<&WorkspaceIndex>,
    page_name: Option<&str>,
    cfg: &DiagnosticConfig,
    utf8: bool,
) -> Vec<Diagnostic>;

Composes:

1. Parse errors (ErrorNode walk; already shipped)
2. Broken-link warnings (Phase 15)
3. (future) other sources

Each gated by cfg. Per-source severity is config-driven.

12.2.5 Wiki aggregate

Single-wiki state becomes a Wiki aggregate, even though Phase 11 only ever builds one entry. Phase 18 then changes config shape, not data structures.

pub struct WikiId(u32);
pub struct WikiConfig {
    pub name: String,
    pub root: PathBuf,
    pub file_extension: String,
    pub syntax: String,
    pub diary_rel_path: String,
    pub html_path: PathBuf,
    pub template_path: PathBuf,
    // … all per-wiki options
}
pub struct Wiki {
    pub id: WikiId,
    pub config: WikiConfig,
    pub index: Arc<RwLock<WorkspaceIndex>>,
}

struct Backend {
    // …
    wikis: Arc<RwLock<Vec<Wiki>>>,
}

impl Backend {
    fn resolve_uri_to_wiki(&self, uri: &Url) -> Option<WikiId>;   // longest-prefix root match
    fn wiki(&self, id: WikiId) -> Option<Arc<Wiki>>;
    fn default_wiki(&self) -> Option<Arc<Wiki>>;
}

WorkspaceIndex itself doesn't gain any new responsibilities in this phase — it just lives inside a Wiki. All v1.0 handlers that today read the single index field get refactored to call default_wiki() (or resolve_uri_to_wiki() where the URI is known).

12.2.6 What does not change

Explicitly out of scope for Phase 11:

• AST shape (no new node kinds — Tags wait for Phase 12)
• LSP capability set (no new providers — capabilities expand from Phase 13)
• HtmlRenderer surface (Phase 17 extends the template substitution set)
• Anything user-visible (this phase is invisible to clients)

12.2.7 Tests

Phase 11 is fully covered by unit tests on the new helpers:

• WorkspaceEditBuilder: multi-uri accumulation, file-op ordering, UTF-16 conversion for non-ASCII spans.
• read_or_open: live doc returns in_memory: true; missing path returns Err; on-disk path returns in_memory: false with parsed AST.
• collect_diagnostics: parse errors emitted; link-health stub returns empty until Phase 15 wires it.
• Config::from_init_options: legacy single-wiki shape desugars to one-entry wikis = [...].
• Backend::resolve_uri_to_wiki: longest-prefix match wins.

12.3 Tags (Phase 12)

Syntax

Vimwiki tags are colon-delimited sequences of non-space characters:

:tag-one:tag-two:other-tag:

Placement rules (matching vimwiki):

• On line 1 or 2 of a file → file-level tag
• Within 2 lines after a = Heading = → header-level tag
• Otherwise → standalone anchor at the source line

AST additions

TagNode (block)
  span:    Span
  tags:    Vec<String>
  scope:   TagScope          -- File | Heading(idx) | Standalone

PageMetadata (extend)
  tags:    Vec<String>       -- file-level tags, accumulated

TagNode slots into BlockNode as a new variant. The Visitor gains visit_tag (default-bodied).

Indexing

WorkspaceIndex extends IndexedPage with:

IndexedPage (extend)
  tags:           Vec<TagInfo>

TagInfo
  name:    String
  scope:   TagScope
  span:    Span

Plus a tags_by_name: HashMap<String, Vec<(Url, Span)>> reverse map. The existing backlink machinery in §6 stays as-is.

LSP behaviour

• tags-as-anchors extends textDocument/definition: [[Page#some-tag]] resolves to the tag's location in the target page (in addition to headings).
• workspace/symbol results include tags (with SymbolKind::PROPERTY or a custom kind).
• New executeCommand operations: nuwiki.tags.search, nuwiki.tags.generateLinks(tag, ...), nuwiki.tags.rebuild (force re-index).

12.4 Workspace edits + executeCommand (Phase 13)

Note on closed documents. When workspace/rename rewrites incoming links across pages that are not open in the editor, the server uses the Phase 11 closed-doc loader (read_or_open) to re-parse them on demand. Stored WorkspaceIndex spans are byte-accurate but may have drifted if the on-disk file changed outside the editor; the re-parse guarantees we emit TextEdits against the current source text and convert to LSP positions correctly (esp. for non-ASCII content under UTF-16 encoding).

Capability

ServerCapabilities {
  execute_command_provider: Some(ExecuteCommandOptions {
    commands: vec!["nuwiki.*", …],
  }),
  rename_provider: Some(true),
  workspace: Some(WorkspaceServerCapabilities {
    file_operations: Some(FileOperationOptions {
      will_rename: Some(...),
      did_rename: Some(...),
      will_delete: Some(...),
      did_delete: Some(...),
    }),
  }),
}

workspace/rename semantics

When a user renames Page A → Page B:

1. Server emits a WorkspaceEdit containing a RenameFile op (A.wiki → B.wiki).
2. For every page in the index that links to A, the edit also rewrites [[A]] → [[B]] (preserving description, anchor, kind).
3. Anchors don't trigger renames — [[A#anchor]] follows.

Custom commands router

A single executeCommand handler dispatches by command name. Every command takes either:

{ uri: Url, position?: Position, range?: Range, ...args }

and returns a WorkspaceEdit (which the client applies via workspace/applyEdit).

12.5 List & table editing commands (Phase 14)

Command	Operates on	Result
nuwiki.list.toggleCheckbox	list item under cursor	[ ] ↔ [X], propagates parent state
nuwiki.list.cycleCheckbox	list item	[ ] → [.] → [o] → [O] → [X] cycle
nuwiki.list.rejectCheckbox	list item	toggle [-] rejected state
nuwiki.list.changeSymbol	list item, args: symbol: ListSymbol, whole_list: bool	rewrite marker, renumber if numeric
nuwiki.list.changeLevel	list item, args: delta: i32, whole_subtree: bool	re-indent + adjust child levels
nuwiki.list.renumber	list, args: whole_file: bool	re-sequence numeric markers
nuwiki.list.removeDone	range or current list	remove every [X] / [-] item and its checked children
nuwiki.list.nextTask	document	navigate to next unfinished task (returns Location, not edit)
nuwiki.table.align	table under cursor	reformat columns to max width
nuwiki.table.moveColumn	cell, args: dir: "left"|"right"	swap column with neighbour
nuwiki.table.insert	cursor, args: cols, rows	insert blank table at cursor
nuwiki.heading.addLevel	heading	promote (== → ===)
nuwiki.heading.removeLevel	heading	demote
nuwiki.link.normalize	word/selection	convert to [[wikilink]], add description if missing
nuwiki.link.pasteWikilink	cursor	paste current page name as an absolute wikilink
nuwiki.link.pasteUrl	cursor	paste the corresponding HTML output URL
nuwiki.colorize	range, args: color: String	wrap in colour tag per color_tag_template

All operations resolve to a textual diff over the existing source so the AST stays the source of truth. None of them rely on editor-side state.

12.6 Link health + TOC/index generation (Phase 15)

Broken-link diagnostics

A new diagnostic source nuwiki.link runs after each parse:

• Wiki target → not in WorkspaceIndex → severity from config (default Warning)
• Anchor target → page exists but anchor doesn't → Warning
• file: / local: → file exists on disk → Warning if missing
• Raw URL / external → never diagnosed (we don't fetch)
• Configurable filtering via diagnostic.link.severity (off|hint|warn|error)

Commands

Command	Behaviour
nuwiki.toc.generate	inserts a nested list of headings in the current page; replaces existing %toc placeholder if present
nuwiki.links.generate	inserts a flat list of all wiki pages (vimwiki's :VimwikiGenerateLinks)
nuwiki.workspace.checkLinks	returns a Vec<BrokenLink> for the client to render in a quickfix-style view; also emits diagnostics
nuwiki.workspace.findOrphans	returns pages with no incoming links

12.7 Diary (Phase 16)

Date parsing. Diary entries use YYYY-MM-DD (and YYYY-Www, YYYY-MM, YYYY for non-daily frequencies). v1.1 ships a small hand-rolled parser/formatter in nuwiki-core for these formats — no chrono / time dependency. The parsable surface is small enough that the dependency cost outweighs the convenience.

Path conventions

<wiki_root>/<diary_rel_path>/         # default: "diary"
  diary.wiki                          # configurable: diary_index
  2026-05-11.wiki                     # daily: YYYY-MM-DD
  2026-W19.wiki                       # weekly: YYYY-Www (configurable)
  2026-05.wiki                        # monthly
  2026.wiki                           # yearly

Custom commands

Command	Behaviour
nuwiki.diary.openToday	open / create today's diary page
nuwiki.diary.openYesterday	analogous
nuwiki.diary.openTomorrow	analogous
nuwiki.diary.openIndex	open the diary index page
nuwiki.diary.generateIndex	rebuild the diary index page with current entries grouped by year/month
nuwiki.diary.next	navigate to the chronologically next diary entry from the current one
nuwiki.diary.prev	analogous

Calendar hook

External plugins (Calendar.vim, neorg-style calendars) can query:

• nuwiki.diary.listEntries(year, month) → list of dates with entries
• nuwiki.diary.openForDate(date) → opens that date's entry

These are executeCommand operations, not LSP standard methods.

12.8 HTML export commands (Phase 17)

The HtmlRenderer from Phase 5 stays as the engine. v1.1 wraps it in user-facing commands and the per-wiki HTML lifecycle.

Per-wiki HTML options

Key	Default	Description
html_path	<wiki_root>/_html	output directory
template_path	<wiki_root>/_templates	template lookup root
template_default	default	base template name
template_ext	.tpl	template extension
template_date_format	%Y-%m-%d	format passed to {{date}}
css_name	style.css	CSS file copied/created at export
auto_export	false	export on save
html_filename_parameterization	false	URL-safe slugs in output filenames
exclude_files	[]	globs to skip

Commands

Command	Behaviour
nuwiki.export.currentToHtml	render current page; honours %template, copies CSS if missing
nuwiki.export.allToHtml	export every page in the wiki
nuwiki.export.allToHtmlForce	:VimwikiAll2HTML! equivalent
nuwiki.export.browse	export current + open default browser to result
nuwiki.export.rss	emit rss.xml of recent diary entries (when diary enabled)

Template variables

The HtmlRenderer template substitution gains:

• {{title}} (already shipped)
• {{content}} (already shipped)
• {{date}} (formatted via template_date_format)
• {{root_path}} (relative path from output to html_path — for stylesheet hrefs in nested pages)
• {{toc}} (rendered TOC for current page)

12.9 Multi-wiki (Phase 18)

Data-structure pre-work. The Wiki aggregate, WorkspaceIndex per-wiki ownership, and Backend::resolve_uri_to_wiki already landed in Phase 11 with a single-entry wikis list. Phase 18 is therefore a config-shape change (accept wikis = [...] from initializationOptions) and resolution-policy change (interwiki links resolve through the matching wiki's index) — not a refactor of the data flow.

Config shape

require('nuwiki').setup({
  wikis = {
    {
      name           = 'personal',
      root           = '~/vimwiki',
      file_extension = '.wiki',
      syntax         = 'vimwiki',
      diary_rel_path = 'diary',
      html_path      = '~/vimwiki/_html',
      -- … any per-wiki option
    },
    {
      name           = 'work',
      root           = '~/work-notes',
      syntax         = 'vimwiki',
    },
  },
  log_level = 'warn',
})

The v1.0 single-wiki shape continues to work; internally it desugars to wikis = [{ root = wiki_root, file_extension = file_extension, syntax = syntax }].

Per-wiki context

WorkspaceIndex becomes one per wiki. Backend holds:

indexes: Arc<DashMap<WikiId, Arc<RwLock<WorkspaceIndex>>>>

URI → wiki resolution walks the URI's filesystem path upward, matching against each registered root. Cross-wiki links (interwiki) resolve through the matching wiki's index.

Custom commands

Command	Behaviour
nuwiki.wiki.select	client-side picker over wikis; resolves to a wiki id
nuwiki.wiki.openIndex	open the selected wiki's index.wiki
nuwiki.wiki.tabOpenIndex	open in new tab (client-side)
nuwiki.wiki.listAll	returns the registered wikis for editor UIs

12.10 Editor glue v2 (Phase 19)

The thickest user-facing layer. Per SPEC §6.3 it still contains no logic — every command body is a wrapper that issues workspace/executeCommand.

:Vimwiki* command compatibility

ftplugin/nuwiki.vim defines every command listed in §4 of vimwiki's help, mapped to the corresponding executeCommand:

Vimwiki command	nuwiki implementation
:VimwikiIndex [count]	nuwiki.wiki.openIndex(count)
:VimwikiTabIndex	tab-open variant
:VimwikiUISelect	nuwiki.wiki.select
:VimwikiDiaryIndex	nuwiki.diary.openIndex
:VimwikiMakeDiaryNote	nuwiki.diary.openToday
:VimwikiMakeYesterdayDiaryNote	nuwiki.diary.openYesterday
:VimwikiMakeTomorrowDiaryNote	nuwiki.diary.openTomorrow
:VimwikiFollowLink	client vim.lsp.buf.definition()
:VimwikiGoBackLink	client <C-o> (jumplist)
:VimwikiSplitLink / :VimwikiVSplitLink	client-side :split/:vsplit + definition
:VimwikiTabnewLink / :VimwikiTabDropLink	client-side :tabnew + definition
:VimwikiNextLink / :VimwikiPrevLink	nuwiki.cursor.nextLink / prevLink
:VimwikiGoto {name}	nuwiki.wiki.gotoPage(name)
:VimwikiDeleteFile	server-side delete via executeCommand
:VimwikiRenameFile	client prompt → workspace/rename
:VimwikiRemoveDone	nuwiki.list.removeDone
:VimwikiNextTask	nuwiki.list.nextTask
:Vimwiki2HTML	nuwiki.export.currentToHtml
:Vimwiki2HTMLBrowse	nuwiki.export.browse
:VimwikiAll2HTML[!]	nuwiki.export.allToHtml[Force]
:VimwikiRss	nuwiki.export.rss
:VimwikiToggleListItem	nuwiki.list.toggleCheckbox
:VimwikiToggleRejectedListItem	nuwiki.list.rejectCheckbox
:VimwikiListChangeLvl CMD	nuwiki.list.changeLevel / changeSymbol
:VimwikiSearch / :VWS	client :lvimgrep wrapper over wiki root
:VimwikiBacklinks / :VWB	client vim.lsp.buf.references()
:VimwikiTable [cols] [rows]	nuwiki.table.insert
:VimwikiTableMoveColumnLeft/Right	nuwiki.table.moveColumn
:VimwikiGenerateLinks	nuwiki.links.generate
:VimwikiDiaryGenerateLinks	nuwiki.diary.generateIndex
:VimwikiDiaryNextDay / :VimwikiDiaryPrevDay	nuwiki.diary.next/prev
:VimwikiTOC	nuwiki.toc.generate
:VimwikiCheckLinks	nuwiki.workspace.checkLinks
:VimwikiRebuildTags	nuwiki.tags.rebuild
:VimwikiSearchTags {tag}	nuwiki.tags.search
:VimwikiGenerateTagLinks	nuwiki.tags.generateLinks
:VimwikiColorize {color}	nuwiki.colorize
:VimwikiPasteLink	nuwiki.link.pasteWikilink
:VimwikiPasteUrl	nuwiki.link.pasteUrl

Each :Vimwiki* form ships with a matching :Nuwiki* alias (P10 resolution).

Default keymaps

g:nuwiki_key_mappings (Vim) / mappings = { … } (Neovim) controls opt-in keymap registration. Default: enabled; group flags let users disable the table/list/heading/diary subsets independently.

Buffer-local maps mirror vimwiki:

• <Leader>ww / <Leader>wt / <Leader>ws / <Leader>wi / <Leader>w<Leader>w etc. — wiki navigation
• <CR> / <S-CR> / <C-CR> / <M-CR> / <C-S-CR> — link follow variants
• <Backspace> / <Tab> / <S-Tab> — link history + per-page link navigation
• = / - / [[ / ]] / [= / ]= / ]u / [u — header manipulation + navigation (pure VimL/Lua, regex over current buffer — no LSP round-trip)
• + — nuwiki.link.normalize
• <C-Space> — nuwiki.list.toggleCheckbox
• gnt — nuwiki.list.nextTask
• gl<Space> / gL<Space> — checkbox remove (single / list)
• gln / glp — checkbox cycle up/down
• gll / gLl / glh / gLh — list level change (single / subtree)
• glr / gLr — list renumber
• gl* / gl# / gl- / gl+ / gl1 / gla / glA / gli / glI — list symbol change (single / subtree variants gL*)
• glx — :VimwikiToggleRejectedListItem
• gqq / gww / gq1 / gw1 — table align
• <A-Left> / <A-Right> — table move column
• <C-Up> / <C-Down> — diary prev/next day
• <Leader>wh / <Leader>whh — HTML export current / browse
• <Leader>wc — colorize (asks for colour)
• <Leader>wn — goto/create new page
• <Leader>wd / <Leader>wr — delete / rename current page
• Mouse: <2-LeftMouse>, <S-2-LeftMouse>, <C-2-LeftMouse>, <RightMouse><LeftMouse> (opt-in via g:nuwiki_mouse_mappings)

Insert-mode behaviour

• Table cells: <CR>/<Tab>/<S-Tab> navigate cells, create rows on overflow; implemented in Lua/VimL via a small autocmd
• Lists: <CR> inserts the next bullet/number; <S-CR> continues without a new bullet; <C-T>/<C-D> indent/dedent; <C-L><C-J>/<C-L><C-K> cycle the list symbol; <C-L><C-M> toggles a list item on/off
• All gated by b:did_ftplugin and remappable

Text objects

omap/xmap defining:

Object	Selects
ah / ih	a header (with/without trailing blank lines + header line itself)
aH / iH	a header + all sub-headers ([count] climbs parent levels)
a\ / i\	a table cell
ac / ic	a table column
al / il	a list item (with/without children)

Pure VimL/Lua — no LSP round-trip. Reuses our AST-shaped regexes.

Folding

Per P14 resolution; the spec'd default (subject to that decision):

• setlocal foldmethod=expr + foldexpr=NuwikiFold(v:lnum) (or LSP foldingRange driving it on Neovim 0.11+)
• Folds at heading boundaries; nested headings nest folds
• List-item folds when configured via g:nuwiki_folding = 'list'
• Custom variant via g:nuwiki_folding = 'custom'

Health check additions

:checkhealth nuwiki v1.1 reports:

• LSP commands registered (per command name)
• Index loaded for each registered wiki
• Tags table built
• HTML output path writable
• Default keymaps installed (or disabled by config)

12.11 Updated user-config schema

require('nuwiki').setup({
  -- single-wiki shorthand (v1.0 compat)
  wiki_root      = '~/vimwiki',
  file_extension = '.wiki',
  syntax         = 'vimwiki',
  log_level      = 'warn',

  -- or the v1.1 multi-wiki form
  wikis = {
    {

      root           = '~/vimwiki',
      file_extension = '.wiki',
      syntax         = 'vimwiki',
      diary_rel_path = 'diary',
      diary_frequency = 'daily',   -- daily | weekly | monthly | yearly
      diary_start_week_day = 'monday',
      template_path  = '~/vimwiki/_templates',
      template_default = 'default',
      template_ext   = '.tpl',

      listsyms       = ' .oOX',
      listsym_rejected = '-',
      listsyms_propagate = true,
      color_dic      = { red = 'red', green = 'green' },
    },
  },

  -- workspace-wide behaviour
  diagnostic = {
    link_severity = 'warn',   -- off | hint | warn | error
  },
  mappings = {
    enabled        = true,
    table_editing  = true,
    list_editing   = true,
    header_nav     = true,

    mouse          = false,
  },
  folding = 'syntax',         -- off | syntax | list | custom
})

12.12 Updated §9 syntax checklist (additions)

The following items extend the v1.0 checklist:

Tags

• Inline tag sequence: :tag-one:tag-two:
• File-level tag (line 1–2 of a wiki page)
• Header-level tag (within 2 lines after a heading)
• Tag-as-anchor target ([[Page#some-tag]])
• Hex-colour code rendering in code blocks (`#ffe119`)

Tables (additions)

• Column-alignment markers in header separator: |:--| / |:--:| / |--:|

Lists (parser extensions)

• Multi-line list item (indented continuation lines)
• Mixed-symbol lists at the same level

12.13 Updated CI/CD

No new workflow files. The existing ci.yaml continues to gate fmt/clippy/test. New phases land behind feature additions in the existing crates; the test suite grows accordingly.

---

13. Pending Implementation

Items specified in earlier phases but not yet implemented. Tracked here so a future audit doesn't have to re-derive the scope from the per-phase prose. Each entry includes the originating SPEC section, why it was deferred, and a sketch of what the implementation needs.

13.1 Phase 14 — list/table/link/colorize commands

Phase 14 shipped a focused subset (checkbox toggle/cycle/reject, nextTask navigation, heading promote/demote). The structural-rewriter commands below were deferred — each needs its own AST-aware rewriter, and they don't share enough scaffolding to land together cheaply.

Command	SPEC	What it does	Sketch
nuwiki.list.changeSymbol	§12.5	Rewrite list marker (- → * → # → 1. …), single item or whole list (whole_list: bool arg).	Locate item span via existing find_list_item_at; rewrite the marker token; if whole_list and numeric, renumber.
nuwiki.list.changeLevel	§12.5	Indent/dedent one item or a subtree (delta: i32, whole_subtree: bool).	Compute leading-whitespace delta per line; re-indent each line of the item span; if subtree, descend into ListItemNode.sublist.
nuwiki.list.renumber	§12.5	Re-sequence numeric markers across a list or a whole file (whole_file: bool).	Walk every ListNode whose symbol is Numeric/NumericParen/AlphaParen/…; rewrite the marker substrings in source order.
nuwiki.list.removeDone	§12.5	Strip [X] / [-] items and their checked children.	Recursive list walker emitting delete spans for matching items; also delete the trailing newline so the surrounding list stays valid.
nuwiki.table.align	§12.5	Reformat columns to max width.	Two-pass: width-per-column scan, then re-render every row with padding; respect > (col span) and \/ (row span) markers.
nuwiki.table.moveColumn	§12.5	Swap column with neighbour (dir: "left" | "right").	Locate TableNode under cursor; for each row, swap cells[col] and cells[col±1]; re-emit.
nuwiki.table.insert	§12.5	Insert blank table at cursor (cols, rows).	Pure string templating; align outputs to current indentation.
nuwiki.link.normalize	§12.5	Convert word/selection to [[wikilink]], add description if missing.	Inspect cursor selection; if a plain word, wrap in [[…]]; if already a wikilink, ensure |description is present.
nuwiki.link.pasteWikilink	§12.5	Paste current page name as an absolute wikilink.	One-line insert; page name from index::page_name_from_uri.
nuwiki.link.pasteUrl	§12.5	Paste the corresponding HTML output URL.	Blocked on Phase 17 (html_path / html_filename_parameterization config).
nuwiki.colorize	§12.5	Wrap range in colour tag per color_tag_template.	Blocked on Phase 17 (color_dic config) — until then the template isn't reachable.

Estimated sequencing

• Cluster A (list rewriters) — changeSymbol, changeLevel, renumber, removeDone share a list-walker pattern. Likely one PR with a shared ops::list_walker helper and four command handlers.
• Cluster B (table rewriters) — align, moveColumn, insert share a column-width pass and a row-by-row re-emitter. Likely a second PR.
• Cluster C (link helpers) — normalize and pasteWikilink are small and don't share much; can land independently.
• Phase-17-blocked — pasteUrl and colorize wait until the HTML export commands land the necessary config keys.

13.2 Phase 13 — will_rename / will_delete capability

The Phase 17 backfill (commit ad1b55a) advertised did_rename and did_delete but intentionally left will_rename / will_delete off. Those variants return a WorkspaceEdit synchronously from the server — useful for, e.g., rewriting all incoming [[Page]] links before a client-initiated file rename commits to disk. Implementation would share most of the cross-doc rewrite logic from rename::compute_rename (Phase 13) but at a different LSP entry point. Deferred because the value proposition over the existing workspace/rename flow is marginal and the editor-side support is inconsistent across clients.

13.3 v1.1 phases 17–19

Tracked in §10 with status ⏳. Not "missing" from earlier phases — they're future work in the v1.1 roadmap:

• Phase 17 — HTML export commands (nuwiki.export.*), template resolution, CSS file management, auto-export. Brings in html_path / template_path / color_dic / etc. config keys.
• Phase 18 — Multi-wiki. Data structures (Wiki aggregate, per-wiki index) already landed in Phase 11; this phase is the config-shape change and the picker commands.
• Phase 19 — Editor glue v2: :Vimwiki* compat layer, default keymaps, text objects, folding (P14 already resolved in favour of LSP foldingRange + foldexpr fallback).

13.4 §9 syntax checklist status

The §9 checklist tracks every vimwiki-syntax surface. Items currently marked [ ] there are parser-level coverage assertions, not missing commands — they're driven by the existing test suite, not by Phase 14+ command work. Don't confuse "syntax checklist unchecked" with "feature missing" — most of those rows are exercised by the parser tests under crates/nuwiki-core/tests/ and just haven't had their checkboxes ticked.
