**Wrap LaTeX table fragments into complete documents for research workflows**

A simple Python tool that transforms statistical programming output (LaTeX table fragments) into compiled PDFs, PNGs, or SVGs. Perfect for researchers who need to quickly inspect, share, and explore tables from Stata, R, Python, and other statistical tools.

**Web Interface**: [tabwrap.janfasnacht.com](https://tabwrap.janfasnacht.com)

## What it does

`tabwrap` takes incomplete LaTeX table fragments like this:
```latex
\begin{tabular}{lcr}
\toprule
Variable & Coefficient & P-value \\
\midrule
Intercept & 1.23 & 0.045 \\
\bottomrule
\end{tabular}
```

And automatically wraps them into complete, compilable LaTeX documents with:
- Auto-detected packages (booktabs, tabularx, siunitx, etc.)
- Proper document structure and preambles
- Smart table resizing to fit pages
- Multi-file batch processing with error recovery
- Combined PDFs with table of contents
- PNG output with automatic cropping, SVG support
- Landscape orientation and custom formatting
- Enhanced error reporting with suggestions

## Quick Start

### Prerequisites

**LaTeX Distribution Required:** tabwrap needs a LaTeX installation to compile documents.

- **Windows**: [MiKTeX](https://miktex.org/download) or [TeX Live](https://tug.org/texlive/)
- **macOS**: [MacTeX](https://tug.org/mactex/) or `brew install --cask mactex`
- **Linux**: `sudo apt-get install texlive-full` or equivalent

**Optional for PNG output**: [ImageMagick](https://imagemagick.org/script/download.php)

### Installation

#### Recommended (CLI tools):

```bash
pipx install tabwrap
```

#### Standard Python installation:

```bash
pip install tabwrap
```

#### With API support:

```bash
pip install tabwrap[api]
```

### Basic Usage

```bash
# Compile a single table
tabwrap regression_table.tex

# Process all tables in a folder
tabwrap ./results_tables/

# Output PNG with landscape orientation
tabwrap table.tex -p --landscape

# Batch process with combined PDF
tabwrap ./tables/ -r -c    # recursive + combine PDFs

# Show filename headers and keep intermediate files
tabwrap data/ --header --keep-tex
```

## Features

### Error Handling

```
⚠️  1 of 3 files failed to compile:

📋 Failed files:
   • bad_table.tex
     Invalid tabular content: No tabular environment found

✅ Successfully compiled: table1.tex, table2.tex
```

### Smart Package Detection

Automatically detects and includes required packages:
- `booktabs` for \\toprule, \\midrule, \\bottomrule
- `tabularx` for \\begin{tabularx}
- `siunitx` for \\SI{}{}, \\num{}
- `multirow` for \\multirow
- And many more...

### Flexible Output Options

```bash
# Output formats
tabwrap table.tex                     # PDF output (default)
tabwrap table.tex -p                  # PNG output with auto-cropping
tabwrap table.tex --svg               # SVG output (vector graphics)

# Batch processing
tabwrap folder/ -r                    # Process subdirectories recursively
tabwrap folder/ -j                    # Parallel processing (4-6x faster)
tabwrap folder/ -c                    # Combine into single PDF with TOC

# Layout and formatting
tabwrap table.tex --landscape         # Landscape orientation
tabwrap table.tex --no-resize         # Disable auto-resizing
tabwrap table.tex --header            # Show filename as header
```

### Shell Completion

tabwrap supports shell completion for bash, zsh, and fish:

```bash
# Bash - add to ~/.bashrc
tabwrap --completion bash >> ~/.bashrc

# Zsh - add to ~/.zshrc
tabwrap --completion zsh >> ~/.zshrc

# Fish - save to completions directory
tabwrap --completion fish > ~/.config/fish/completions/tabwrap.fish
```

## CLI Reference

```
Usage: tabwrap [OPTIONS] [INPUT_PATH]

Arguments:
  INPUT_PATH               .tex file or directory to process [default: current directory]

Output Options:
  -o, --output PATH        Output directory [default: current directory]
  --suffix TEXT            Output filename suffix [default: _compiled]
  -p, --png                Output PNG instead of PDF
  --svg                    Output SVG instead of PDF

Processing Options:
  -r, --recursive          Process subdirectories recursively
  -j, --parallel           Process files in parallel for faster batch compilation
  --max-workers INTEGER    Maximum number of parallel workers [default: CPU cores]
  -c, --combine            Combine multiple PDFs with table of contents

Formatting Options:
  --landscape              Use landscape orientation
  --no-resize              Disable automatic table resizing
  --header                 Show filename as header in output
  --packages TEXT          Comma-separated LaTeX packages (auto-detected if empty)
