# smd (Simple Markdown Viewer) image image > [!WARNING] > **DISCLAIMER: This project is currently in alpha stage. It may contain bugs, incomplete features, or undergo significant changes. Use with caution and please report any issues you encounter.** smd is a minimalistic Markdown renderer for the terminal with syntax highlighting, emoji support, and image rendering. It provides a visually appealing way to view Markdown content directly in your console. ## Motivation The primary goal of smd is to create CLI documentation in Markdown that can be rendered both in the terminal and viewed in a web browser. This dual-format approach aims to: 1. Provide a unified documentation format accessible across different environments 2. Enable quick viewing end editing of cli documentations from anywhere As the project evolved, support for more complex Markdown features was added. This expansion opens up possibilities for integration with other documentation tools and workflows, potentially enhancing its utility in diverse development ecosystems. ## Features - Rich text rendering in the terminal - Syntax highlighting for code blocks - Emoji support :smile: - Image rendering (when possible) - Clickable links (in supported terminals) - Table formatting - Task list rendering - Nested list support - Blockquote styling - And more adding soon! ## Installation There are several ways to install smd: ### 1. Install prebuilt binaries via shell script (Recommended) The easiest and fastest way to install smd is by using our shell script: ```sh curl --proto '=https' --tlsv1.2 -LsSf https://github.com/guilhermeprokisch/smd/releases/download/v0.2.10/smd-installer.sh | sh ``` **DISCLAIMER: The version number in the URL above (v0.2.10) may not be the latest version. Please check the [releases page](https://github.com/guilhermeprokisch/smd/releases) for the most recent version and update the URL accordingly before running the command.** ### 2. Using prebuilt binaries from GitHub releases If you prefer to manually download and install the binary: 1. Visit the [smd releases page](https://github.com/guilhermeprokisch/smd/releases) on GitHub. 2. Find the latest release version. 3. Download the appropriate binary for your operating system and architecture. 4. Extract the downloaded file if necessary. 5. Move the `smd` binary to a directory in your system's PATH (e.g., `/usr/local/bin` on Unix-like systems). ### 3. Install prebuilt binaries via Homebrew If you're using Homebrew, you can install smd with: ```sh brew install guilhermeprokisch/smd/smd ``` ### 4. Using Cargo You can install smd directly from crates.io using Cargo: ```bash cargo install smd ``` This will download, compile, and install the latest version of smd. Make sure your Rust installation is up to date. ### 5. Building from Source If you prefer to build from source or want to contribute to the project: 1. Ensure you have Rust and Cargo installed. If not, get them from [https://rustup.rs/](https://rustup.rs/). 2. Clone the repository: ```bash git clone https://github.com/guilhermeprokisch/smd.git cd smd ``` 3. Build and install the project using Cargo: ```bash cargo install --path . ``` This will compile the project and install the `smd` binary in your Cargo bin directory, which should be in your PATH. ## Usage There are two main ways to use smd: ### 1. Rendering a Markdown file To render a Markdown file, simply pass the path to the file as an argument: ```bash smd path/to/your/markdown_file.md ``` ### 2. Rendering Markdown from piped input smd can also read Markdown content from standard input, allowing you to pipe content directly into it: ```bash echo "# Hello, *world*" | smd ``` This feature is particularly useful for integrating smd with other commands or for quickly rendering Markdown snippets. For example: ```bash cat README.md | smd # Render a file's content curl -sL https://raw.githubusercontent.com/guilhermeprokisch/smd/master/README.md | smd # Render a remote Markdown file ``` #### Integration with CLI Tools smd can be easily integrated with CLI tools to replace traditional man pages with rich Markdown documentation. Here's an example of how you can use smd with a custom CLI tool's --help flag: ```bash #!/bin/bash # Name: mycli # Description: Example CLI tool using smd for documentation if [[ "$1" == "--help" ]]; then # Use smd to render the Markdown help file smd ~/.mycli/help.md else # Regular CLI functionality echo "Running mycli with arguments: $@" fi ``` In this example, create a Markdown file at `~/.mycli/help.md` with your CLI documentation. When users run `mycli --help`, they'll see a beautifully rendered version of your Markdown documentation instead of a plain text man page. image This approach allows you to maintain a single source of documentation that's readable in raw form, rendered nicely in the terminal, and viewable in web browsers. #### Viewing smd's Own Documentation smd uses itself to display its own documentation. You can view smd's documentation directly in your terminal by running: ```bash smd --help ``` This command will render smd's main documentation file `/docs`, giving you a practical example of smd in action and providing detailed information about its usage and features. ## Configuration smd supports user-defined configuration files. You can customize various aspects of the rendering process by creating a `config.toml` file in the following location: - On Linux and macOS: `~/.config/smd/config.toml` - On Windows: `C:\Users\\AppData\Roaming\smd\config.toml` You can generate a default configuration file by running: ```bash smd --generate-config ``` Here's an example of what you can configure: ```toml max_image_width = 40 max_image_height = 13 render_images = true render_links = true render_table_borders = false ``` - `max_image_width` and `max_image_height`: Maximum dimensions for rendered images - `render_images`: If false, images will not be rendered - `render_links`: If false, links will not be clickable - `render_table_borders`: If true, tables will be rendered with ASCII borders (default: false) ## Contributing Contributions are welcome!
