❓ About

go-grip is a lightweight, Go-based tool designed to render Markdown files locally, replicating GitHub's style. It offers features like syntax highlighting, dark mode, and support for mermaid diagrams, providing a seamless and visually consistent way to preview Markdown files in your browser.

This project is a reimplementation of the original Python-based grip, which uses GitHub's web API for rendering. By eliminating the reliance on external APIs, go-grip delivers similar functionality while being fully self-contained, faster, and more secure - perfect for offline use or privacy-conscious users.

This is an inline $\sqrt{3x-1}+(1+x)^2$ function.

$$\left( \sum_{k=1}^n a_k b_k \right)^2 \leq \left( \sum_{k=1}^n a_k^2 \right) \left( \sum_{k=1}^n b_k^2 \right)$$

$$\left( \sum_{k=1}^n a_k b_k \right)^2 \leq \left( \sum_{k=1}^n a_k^2 \right) \left( \sum_{k=1}^n b_k^2 \right)$$

🚀 Getting started

To install go-grip, simply:

go install github.com/chrishrb/go-grip@latest

Tip

You can also use nix flakes to install this plugin. More useful information here.

🔨 Usage

To render the README.md file simply execute:

go-grip README.md
# or
go-grip

The browser will automatically open on http://localhost:6419. You can disable this behaviour with the -b=false option.

You can also specify a port:

go-grip -p 80 README.md

or just open a file-tree with all available files in the current directory:

go-grip -r=false

It's also possible to activate the darkmode:

go-grip -d .

To disable automatic browser reload on file changes (useful for stable editing):

go-grip --no-reload README.md

To terminate the current server simply press CTRL-C.

📝 Examples

🐛 Known TODOs / Bugs

• Maybe use githubs original mermaid renderer with zoom option etc. (https://viewscreen.githubusercontent.com/markdown/mermaid?docs_host=https%3A%2F%2Fdocs.github.com&color_mode=dark#a5f40142-95a0-45db-8a9a-e1fb39a6488b)
• Make it possible to export the generated html
