Ma.nvim

A minimal knowledge layer for Markdown in Neovim.

Ma.nvim lets structure emerge from filenames rather than directories. Notes live in a flat filesystem, while hierarchy is inferred through dot-separated segments and hyphenated words.

Inspired by Dendron and Obsidian, Ma provides vault-scoped navigation and safe file operations without imposing a folder-based structure.

Why Ma?

Ma (間) is a Japanese concept often translated as interval or space between.

It does not mean emptiness as absence. It refers to meaningful space: the gap that makes relationships possible.

In Ma.nvim, structure is not imposed through folders. It emerges in the intervals:

• Dots define hierarchy.
• Hyphens define words.
• Meaning lives in the space between segments.

Ma also implies time: the pause between actions, the space we take to write, reflect, and connect ideas in plain text.

Example file name

architecture.norman-foster.apple-piazza-liberty.md

Ma interprets this as a hierarchy:

📁 architecture
└ 📁 norman-foster
  └ 📄 apple-piazza-liberty

Getting Started

Requirements

• Neovim >= 0.11.0

Dependencies

Required:

• nvim-lua/plenary.nvim
• nvim-telescope/telescope.nvim for navigator and vault picker

Optional:

• nvim-tree/nvim-web-devicons for filetype-aware file icons in the icons column. If missing, Ma falls back to built-in defaults ( for folders, 󰈙 for files).
• telescope-fzf-native.nvim for faster picker matching.
• Marksman (Markdown LSP) for gd on links, semantic link resolution, and document symbols.

Installation

Pinning to the latest release tag is recommended.

With lazy.nvim:

{
  "gmcusaro/ma.nvim",
  version = "*",
  dependencies = {
    "nvim-lua/plenary.nvim",
    "nvim-telescope/telescope.nvim",
    { "nvim-telescope/telescope-fzf-native.nvim", build = "make" },
    { "nvim-tree/nvim-web-devicons", opts = {} },
  },
  opts = {
    vaults = {
      { name = "My Brain", path = "~/notes" },
    },
  },
}

Default Setup

require("ma").setup({
  vaults = {
    { name = "My Brain", path = "~/notes" },
  },
  respect_gitignore = true,
  autochdir = "lcd",
  depth = nil,
  delete_to_trash = true,
  picker_actions = {
    { "c", "create" },
    { "r", "rename" },
    { "d", "delete" },
  },
  date_format_frontmatter = "%Y %b %d - %H:%M:%S",
  telescope = {},
  columns = { "git", "icons" },
  sort = { by = "name", order = "asc" },
  daily_notes = {
    date_format = nil,
    locale = nil,
  }
})

Commands

:Ma

Open the Telescope navigator for the active root. Use it to browse notes as a dot-based tree and run picker actions.

:Ma vault / :Ma vault <name>

Pick and switch the active vault.

• :Ma vault opens the vault picker and switches the active vault.
• :Ma vault <name> switches directly to an existing configured vault by name.

When a vault is selected, Ma sets it as active and reopens navigation in that vault. The active root is the currently selected vault path, or Neovim's current working directory if no valid vault is configured.

Use when:

• You keep separate note collections (personal, work, research).

:Ma create

Create or open a note from the command line.

Behavior:

• If the note exists, Ma opens it.
• If it does not exist, Ma prompts for file name, title, and optional description, writes frontmatter, then opens it.

Name handling:

• .md is added automatically if omitted.
• Existing .md or .markdown suffixes are normalized and not duplicated.
• / is normalized to ..
• Spaces are normalized to -.

The final segment of the name always creates a file. Ma does not create standalone "folders"; hierarchy exists conceptually through dot-separated segments.

Use when:

• You want a quick create/open flow outside the Telescope picker.

:Ma daily

Create or open the daily note. Use it to keep daily journal/log notes.

Builds daily.<formatted-date>.md using daily_notes options.

:Ma rename

Rename the current managed note. Works only for markdown files under the active root. This command renames only the current note file.

Use when:

• You want to rename the current note without opening the picker.

Picker folder rename (multi-file):

• In the navigator picker, renaming a folder segment updates all notes sharing that segment prefix.

Example:

• Renaming a folder segment architecture.foster.apple-piazza-liberty into architecture.norman-foster.apple-piazza-liberty
• Also renames notes such as architecture.foster.30-st-mary-axe architecture.foster.millennium-bridge into architecture.norman-foster.30-st-mary-axe architecture.norman-foster.millennium-bridge

:Ma delete

Delete the current note with confirmation. Works only for managed markdown notes under the active root. In the navigator picker, multi-select deletion is supported via Telescope multi-select. Uses trash-first or hard-delete mode (see delete_to_trash).

:Ma link

Create a markdown link from the current visual selection. Prompts for target note, opens/creates it, and replaces selection with [label](target.md). The target note name is normalized and lowercased.

Important:

• Run this from visual mode inside a managed markdown note.

Use when:

• You are writing and want fast create-and-link behavior.

Picker Behavior

• Enter: open folder/file.
• Backspace (normal mode): go up when prompt is empty.
• - (normal mode): force go up.
• Ctrl-h (insert mode): force go up.
• Action keys come from picker_actions in normal mode.
• Multi-select + delete is supported in the picker delete action.

Configuration Reference

vaults

List of vault roots Ma can use as note workspaces.

Type:

• { { name?: string, path: string } } | nil

Default:

• {}

Behavior:

• Invalid/non-existing paths are ignored
• Duplicate paths are deduplicated.
• Missing/empty name falls back to folder basename.
• First valid vault becomes active by default.
• If no valid vault exists, Ma.nvim uses current working directory.

Example:

vaults = {
  { name = "Personal", path = "~/notes/personal" },
  { name = "Work", path = "~/notes/work" },
}

Important:

• If no valid vault exists, Ma uses Neovim's current working directory.

Use when:

• You want explicit, switchable note roots.

respect_gitignore

Control whether scans exclude files ignored by .gitignore.

Type:

• boolean

Default:

• true

Example:

respect_gitignore = false

Use when:

• Set to false only if you intentionally want ignored markdown files included.

autochdir

Control whether Ma changes Neovim's working directory to the active root before major actions.

Type:

• false | "lcd" | "tcd" | "cd"

Default:

• "lcd"

Behavior:

• false: no directory change.
• "lcd": window-local cwd.
• "tcd": tab-local cwd.
• "cd": global cwd.

Example:

autochdir = "tcd"

Important:

• Applied when navigating, linking, creating, and opening daily notes.

Use when:

• You want Ma's root and your relative-path tools to stay aligned.

depth

Maximum directory recursion depth during note scanning.

Type:

• integer | nil

Default:

• nil

Behavior:

• nil: unlimited recursion.
• integer: scan only up to that depth.

Example:

depth = 3

Use when:

• Your vault is large and you want faster scans.

delete_to_trash

Choose trash-first deletion or direct deletion.

Type:

• boolean

Default:

• true

Behavior:

• When true, Ma tries OS trash tools first (osascript on macOS, gio, trash-put, kioclient5) and falls back to file removal.

Example:

delete_to_trash = true

Important:

• Even with trash mode, fallback behavior can permanently delete files if no trash backend is available.

Use when:

• You want safer delete operations.

picker_actions

Keybindings available inside the navigator picker.

Type:

• { { string, "create"|"rename"|"delete" } } | { [string]: "create"|"rename"|"delete" } | false

Default:

{
  { "c", "create" },
  { "r", "rename" },
  { "d", "delete" },
}

Behavior:

• false disables picker actions.
• List order is preserved.
• Legacy map forms are still accepted.

Example:

picker_actions = {
  { "n", "create" },
  { "x", "delete" },
}

Use when:

• You want custom action keys in Telescope.

date_format_frontmatter

Date format for created and updated frontmatter fields.

Type:

• string

Default:

• "%Y %b %d - %H:%M:%S"

Behavior: Used for created/updated timestamps in frontmatter. updated is refreshed only if:

• frontmatter exists at top of file
• frontmatter already has an updated: key

Example:

date_format_frontmatter = "%Y-%m-%d %H:%M"

Important:

• Ma updates updated: only if frontmatter exists at top of file and already contains an updated key.

Use when:

• You need a specific timestamp style across notes.

telescope

Override Telescope picker options specifically for Ma.

Type:

• table

Default:

• {}

Behavior:

• Supported keys are: prompt_prefix, selection_caret, initial_mode, and layout_config.
• initial_mode accepts only "insert" or "normal".
• Other Telescope keys are ignored by Ma.

Supported options are documented in the Telescope README.

Example:

telescope = {
  prompt_prefix = " ",
  selection_caret = "| ",
  initial_mode = "normal",
  layout_config = {
    prompt_position = "top",
    width = 0.9,
    height = 0.9,
    preview_width = 0.6,
    mirror = false,
    preview_cutoff = 120,
  },
}

Use when:

• You want Ma pickers to match your Telescope UX.

columns

Choose which navigator columns are shown and in what order.

Type:

• table

Default:

{ "git", "icons" }

Behavior:

• Supported column names: "git", "icons".
• Order in the array controls display order.
• If git column is not active, Ma skips Git status computation.

Use when:

• You want simpler or more informative picker rows.

columns.git

Nested key inside columns used to override Git status symbols for the git column.

Type:

• table

Default:

• nil (unset)

Built-in symbols (used when git column is enabled):

{
  clean = "  ",
  modified = "M ",
  added = "A ",
  deleted = "D ",
  renamed = "R ",
  copied = "C ",
  untracked = "? ",
  ignored = "! ",
  conflicted = "U ",
  unknown = "~ ",
}

Behavior:

• Providing git = {...} auto-enables the git column if missing.
• If you override symbols, statuses not explicitly set may render as blank.

Example:

columns = {
  git = {
    modified = "✱ ",
    untracked = "… ",
    conflicted = "‼ ",
  },
  "icons",
}

columns.icons

Nested key inside columns used to customize folder/file icons in the icons column.

Type:

• { folder?: string, file?: string }

Behavior:

• icons = {...} auto-enables the icons column if missing.
• A non-empty icons.folder or icons.file value is used directly.
• Without a custom folder icon, Ma uses fallback .
• Without a custom file icon, Ma uses nvim-web-devicons when available, else fallback 󰈙.

Examples:

-- default
columns = { "git", "icons" }

-- custom fixed icons (dependency optional)
columns = {
  "git",
  icons = {
    folder = "F ",
    file = "md",
  },
}

Use when:

• You want explicit icon behavior with or without nvim-web-devicons.

sort

Sort strategy for entries in each picker level.

Type:

• { by?: "name"|"update"|"creation", order?: "asc"|"desc" }

Default:

{ by = "name", order = "asc" }

Behavior:

• name: case-insensitive by segment text.
• update: by file mtime.
• creation: by birthtime/ctime fallback.
• Ties fall back to full note path for deterministic order.

Example:

sort = { by = "update", order = "desc" }

Use when:

• You want recency-first or chronology-first navigation.

daily_notes

Enable/disable daily note generation and control date formatting.

Type:

• table | false

Default:

{ date_format = nil, locale = nil }

Behavior:

• false: disables :Ma daily.
• table: creates/opens daily.<date>.md.

Example:

daily_notes = {
  date_format = "%Y.%b.%d",
  locale = "en_US.UTF-8",
}

Example output: daily.2026.Mar.03.md

Use when:

• You maintain date-based daily notes.

daily_notes.date_format

Date token pattern used in daily note filename and title.

Type:

• string | nil

Default:

• "%Y.%b-%d" (when nil)

Behavior:

• Uses Lua os.date/strftime-style tokens.

Example:

daily_notes = { date_format = "%Y-%m-%d" }

Important:

• Since this value becomes part of the note name, separators (. and -) affect hierarchy and readability.

Use when:

• You want ISO-like names or locale-friendly names.

daily_notes.locale

Locale used while formatting daily note dates.

Type:

• string | nil

Default:

• nil (current process locale)

Behavior:

• Temporarily applies os.setlocale(locale, "time"), formats the date, then restores previous locale.

Example:

daily_notes = { locale = "it_IT.UTF-8" }

Use when:

• You want month/day names in a specific language.

Frontmatter

When creating a new note via :Ma create or :Ma daily, Ma generates YAML frontmatter with this structure:

---
id: <23-char random id>
title: <title>
desc: <desc>
updated: <formatted timestamp>
created: <formatted timestamp>
---

Behavior:

• Frontmatter is written only when a note file is newly created; opening an existing note does not insert or rewrite frontmatter.
• created and updated use date_format_frontmatter.
• updated is refreshed on BufWritePre for managed markdown files under the active root.
• updated is only modified if frontmatter exists and contains an updated: field.
• Notes without frontmatter are left untouched.
• id is generated automatically and is not currently used for indexing or linking.
