Provide a Glamour CLI tool

[Chris Gilmer]

I'm using charmbracelet/gum and realized I didn't have a good way to use this project to format markdown files. Ideally I'd be able to use gum pager --glamour < myfile.md . I'm not sure if the team would even want glamour built into gum so I thought a better solution would be glamour myfile.md | gum pager for my needs. I used the code below to build it. Would this project be interested in including a CLI tool for glamour that we could install with brew on mac or on linux? I'm sure a more full-featured CLI tool could be built.

package main

import (
	"fmt"
	"os"

	"github.com/charmbracelet/glamour"
)

func main() {
	if len(os.Args) < 2 {
		fmt.Println("Usage: glamour <filename.md>")
		os.Exit(1)
	}

	markdownFile := os.Args[1]
	markdownContent, err := os.ReadFile(markdownFile)
	if err != nil {
		fmt.Println("Error reading Markdown file:", err)
		os.Exit(1)
	}

	renderer, err := glamour.NewTermRenderer(
		glamour.WithAutoStyle(),
	)
	if err != nil {
		fmt.Println("Error creating Glamour renderer:", err)
		os.Exit(1)
	}

	formattedOutput, err := renderer.RenderBytes(markdownContent)
	if err != nil {
		fmt.Println("Error formatting Markdown content:", err)
		os.Exit(1)
	}

	fmt.Println(string(formattedOutput))
}

Hey @chrisgilmerproj, maybe we need to document this better but I think gum format is what you might be looking for:

gum format --format markdown --theme dark file.md

[Chris Gilmer]

@maaslalani - You are correct. What I needed was:

gum format --theme dark --type markdown < file.md

This helps a lot. Sorry for opening the ticket here. I might suggest putting this in the README.md for this project and linking over to gum. Thanks.

I should mention that I am not entirely clear how to use gum pager and gum format together. If you could help me out I'd appreciate it.
