FullMark

A really useful markdown editor. Notion-style power. Cursor-quality readability. Plain .md files.

FullMark is a desktop markdown editor that combines the block-based editing model of Notion with the rendering quality of Cursor's markdown view — over plain .md files on disk. No proprietary format, no lock-in, no AI features.

Status: pre-alpha. Under active development.

Features

• Notion-style block editor — type / for a slash menu of block insertions, or use markdown shortcuts (#, -, >, ``` etc.)
• Beautiful rendering — typography-first design, warm color palette, syntax-highlighted code blocks
• Plain .md files — open any folder of markdown as a workspace. Your data stays yours.
• [[wikilinks]] rendered as chips — Obsidian-compatible
• Atomic writes — temp file + fsync + rename, so a crashed process can't corrupt your notes
• Cmd+K quick switcher — fuzzy search across all files in the workspace
• Cmd+R reader mode — strip chrome and lock editing for focused reading
• Light / dark / system theme — follows your OS by default; cycle with the ◐ button in the sidebar
• Smart typography — -- → em-dash, "x" → curly quotes, ... → ellipsis, automatically
• Native "Open With…" registration — right-click any .md in Finder

Not included by design: AI features, cloud sync, real-time collaboration, mobile apps.

Install

Option A — Homebrew (recommended)

brew install --cask thedumsieffect/tap/fullmark

FullMark is ad-hoc signed but not Apple-notarized, so the first time you launch it macOS will show an "unidentified developer" dialog. Right-click /Applications/FullMark.app → Open → confirm. After that, it launches normally.

Update later:

brew upgrade --cask fullmark

Option B — DMG (macOS, Apple Silicon)

1. Download the DMG from the latest release — direct link: FullMark_0.1.5_aarch64.dmg (~3.5 MB).

2. Open the .dmg and drag FullMark.app into your Applications folder.

3. First launch: because the app isn't notarized yet, macOS Gatekeeper will block it. Either:

   • Right-click FullMark.app → Open → confirm in the dialog, or
   • Run once via terminal: xattr -dr com.apple.quarantine /Applications/FullMark.app

4. "Open With FullMark": the first launch registers the app as a .md handler with Launch Services automatically. After that, right-click any .md file in Finder → Open With → FullMark. If you don't see the entry immediately, force a Launch Services rescan:

   /System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister \
     -kill -r -domain local -domain system -domain user

Option C — Build from source

Prereqs (one-time setup):

# 1. Node ≥20 and pnpm — easiest via nvm + corepack, or use brew:
brew install node pnpm

# 2. Rust stable (Tauri compiles the shell in Rust):
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh -s -- -y
. "$HOME/.cargo/env"   # pick up cargo in the current shell

# 3. Xcode Command Line Tools (needed for the linker on macOS):
xcode-select --install

Then:

git clone https://github.com/thedumsieffect/fullmark.git
cd fullmark
pnpm install
pnpm tauri build     # produces src-tauri/target/release/bundle/dmg/FullMark_*.dmg + .app

To build and then install the generated app from the DMG into /Applications, use the prompted helper:

pnpm build:install

For development:

pnpm tauri dev       # hot-reload window

Common build errors:

• failed to run command cargo metadata → Rust isn't installed or cargo isn't on $PATH. Run step 2 above, then . "$HOME/.cargo/env" in the current shell (or restart your terminal).
• xcrun: error: invalid active developer path → Run step 3 above.
• error: linker 'cc' not found → Same fix, Xcode CLT.

Usage

1. Launch FullMark. The Welcome screen offers an Open folder… button.
2. Pick any folder containing .md files. The sidebar shows only markdown files; everything else is filtered out by design.
3. Click a file to open it in a tab. Edit. Changes save automatically 1.5 s after you stop typing, or on Cmd+S.
