mark2tex 0.3.1

Markdown to TeX/PDF with TUI and Docker

Mark2TeX

English | Português (Brasil)

Write Markdown. Get a polished academic PDF.
A Dockerized pipeline with an interactive TUI for LaTeX-quality documents — no TeX installation required.

What is Mark2TeX?

Mark2TeX is a command-line tool that converts Markdown files into publication-ready PDFs using Pandoc, XeLaTeX, and pre-built LaTeX templates — all inside a Docker container. You write plain text; Mark2TeX handles the typography.

Why Mark2TeX instead of writing LaTeX directly?

	LaTeX	Mark2TeX
Learning curve	Steep	Write plain Markdown
Environment setup	4 GB+ TeX distribution	Only Docker
Error messages	Cryptic logs	Human-readable translations
Live feedback	Manual re-run	Watch mode auto-recompiles

Quickstart

Why pipx? Mark2TeX is a CLI tool, not a library. pipx installs Python CLI tools in isolated environments automatically — without polluting your system Python or requiring a manual venv. If you don't have pipx yet:

# Ubuntu / Debian
sudo apt install pipx && pipx ensurepath

# macOS
brew install pipx && pipx ensurepath

# Windows (PowerShell)
python -m pip install --user pipx
python -m pipx ensurepath

Restart your terminal after running ensurepath.

# 1 — install (requires Python 3.10+ and Docker)
pipx install mark2tex

# 2 — check your environment (recommended on first install)
mark2tex check

# 3 — open the TUI dashboard (Docker image is pulled automatically)
mark2tex

First run: Mark2TeX automatically pulls the mark2tex image from Docker Hub with a Rich visual progress bar — one bar per image layer showing download speed, file size, and estimated time remaining. Requires an active internet connection; may take a few minutes depending on your speed. Subsequent runs reuse the cached image.

No internet? If Docker Hub is unreachable, Mark2TeX falls back to building the image locally from the bundled Dockerfile (spinner shown during build steps). You can also run make build-image manually at any time.

Welcome screen: On the very first launch, a welcome screen guides you through the workflow. Click "Initialise project here" to copy a ready-to-edit example .md file directly into your current directory — no need to leave the app. You can also run mark2tex init from the terminal at any time to do the same thing.

CLI Commands

Command	Description
mark2tex	Open the interactive TUI dashboard (default)
mark2tex check	Run a full system health check
mark2tex init [--template NAME]	Copy a template + example into the current directory
mark2tex restore <file>	Restore a .md file to its state before YAML injection
mark2tex clean [file]	Wipe the latexmk build cache — all docs or a specific one
mark2tex uninstall	Remove Docker images, user data, and config dirs — run before pipx uninstall mark2tex
mark2tex doctor	Alias for check (deprecated — use check)

mark2tex check — System Health Report

Runs six probes and prints a visual report:

──────────────── Mark2TeX — System Check  v0.2.2 ────────────────

✅   Mark2TeX          0.2.2
✅   Docker binary     /usr/bin/docker
✅   Docker daemon     active
✅   Image mark2tex    mark2tex:latest (1 143 MB)
⚠️   Pandoc            not found (optional)
                          Pandoc is bundled in the Docker image — host installation not required.
✅   Python            3.12.3

─────────────────────────────────────────────────────────────────
  5 OK  ·  1 warning  ·  0 errors

  Review the warnings above before compiling.

Exit code 0 when no errors are found; exit code 1 when at least one error probe fails — making it scriptable in CI pipelines.

TUI at a Glance

1. Select a .md file from the left panel.
2. Choose a template (tcc-abnt, artigo-ieee, doc-tecnica, projeto).
3. Optionally pick a font (Liberation Serif, Liberation Sans, Nimbus Sans, Ubuntu).
4. Press c to compile or w to toggle Watch Mode.
5. Preview the Markdown file
6. Monitor real-time console output

Keyboard shortcuts

Key	Action
c	Compile

Esc / q	Global menu

Features

• Dockerized builds — zero local LaTeX installation; identical output on every machine.
• Interactive TUI — file browser, template selector, real-time log console, and progress bar built with Textual.
• Directory navigation — the file panel opens at the current working directory. Subdirectories are listed before .md files; press Enter on a folder to enter it. A ../ entry at the top of the list navigates back to the parent folder.
• First-run onboarding — welcome screen shown on the first launch with a built-in "Initialise project here" button that copies an example .md into your current directory without leaving the app.
• Watch mode — automatic recompilation on every file save; temp/swap files (.swp, .bak, ~) are ignored; debounce of 1.5 s prevents double-triggers on two-stage saves (e.g. Obsidian).
• Incremental builds — latexmk persists intermediate files (.aux, .fdb_latexmk, .fls) in an OS-standard user cache directory. Re-compilation after a single-line edit takes ~6 s instead of ~18 s on a 15-page document.
• Compile timeout — a 5-minute timeout (overridable via MARK2TEX_TIMEOUT) prevents hanging builds from locking the UI indefinitely.
• Exclusive worker — pressing c twice or a Watch Mode trigger during a running build cancels the previous worker before starting a new one, eliminating interleaved log output.
• Frontmatter validator — before each compilation the YAML frontmatter is checked for missing required fields, unfilled placeholder values, template mismatches, and invalid lang codes. Warnings appear in the TUI console; critical errors abort the build early.
• Template swap — switching templates in the TUI surgically updates template: and date: in the frontmatter, adds missing fields with placeholders, and removes fields exclusive to the old template — all without touching the values you already filled in.
• Human-readable logs — raw XeLaTeX output is parsed and translated into plain-language messages.
• Font selection — choose between Liberation Sans (Arial-compatible), Nimbus Sans (Helvetica), Liberation Serif (Times-compatible), and Ubuntu per document.
• Bibliography support — BibTeX via Pandoc + XeLaTeX; just drop a referencias.bib alongside your .md. BibTeX is only invoked when actual citation markers are present in the source.
• System health check — mark2tex check diagnoses your environment before you compile.
• Rich image pull progress — per-layer progress bars with speed and ETA when pulling the Docker image on first run.
• YAML frontmatter injection — files without a YAML header are highlighted in amber in the TUI; a confirmation modal injects the frontmatter automatically before compilation. A backup is saved to ~/.local/share/mark2tex/backups/ and can be restored at any time with mark2tex restore <file>.
• Build cache management — mark2tex clean [file] removes the latexmk cache for all documents or a specific one.
• ABNT-oriented workflow — templates built around Brazilian academic standards, with polyglossia for correct pt-BR hyphenation and setspace for ABNT-required 1.5 line spacing.

Available Templates

Template	Purpose
tcc-abnt	Undergraduate thesis (ABNT)
artigo-ieee	IEEE conference paper
artigo-abnt	ABNT journal article
doc-tecnica	Technical documentation
projeto	Project proposal

Roadmap

• System health check (mark2tex check)
• First-run onboarding with Rich progress for Docker image pull
• Welcome screen with guided workflow and "Initialise project here" button
• mark2tex init — scaffold a template into the current directory
• Auto-inject YAML frontmatter for files without it (with backup & restore)
• Directory tree traversal in the file panel (subdirs + ../ navigation)
• Frontmatter validator — missing fields, placeholders, template mismatch, lang validation
• Template swap — preserve user values when switching templates in the TUI
• Incremental latexmk builds with OS-standard user cache
• Compile timeout with MARK2TEX_TIMEOUT override
• Exclusive compilation worker (cancel-and-restart)
• mark2tex clean — wipe latexmk build cache
• Watch Mode race-condition fix (abort stale container before new Pandoc run)
• Additional ABNT templates (dissertation, presentation)
