# Docster

A self-contained CLI tool that converts Markdown with Mermaid diagrams into PDF or HTML using Pandoc and Mermaid CLI.

## Usage

    docster -pdf path/to/file.md
    docster -html path/to/file.md

Mermaid code blocks (```mermaid) will be rendered to SVG and embedded.

## Installation

### Prerequisites

First install the required system dependencies:

```bash
./install-deps.sh
```

### Install Haskell toolchain

Install ghcup (Haskell toolchain installer):

```bash
curl --proto '=https' --tlsv1.2 -sSf https://get-ghcup.haskell.org | sh
source ~/.ghcup/env
```

Install specific GHC and Cabal versions:

```bash
ghcup install ghc 9.12.2
ghcup install cabal 3.16.0.0
ghcup set ghc 9.12.2
ghcup set cabal 3.16.0.0
```

### Install Mermaid CLI

```bash
npm install -g @mermaid-js/mermaid-cli
```

### Build and install docster

```bash
cabal install --installdir=$HOME/.local/bin
```

Make sure `~/.local/bin` is in your PATH. Add to your shell config if needed:

```bash
export PATH="$HOME/.local/bin:$PATH"
```
