What is it?

Glow is a terminal based markdown reader designed from the ground up to bring out the beauty—and power—of the CLI.

Use it to discover markdown files, read documentation directly on the command line. Glow will find local markdown files in subdirectories or a local Git repository.

Installation

Package Manager

# macOS or Linux
brew install glow

# macOS (with MacPorts)
sudo port install glow

pacman -S glow

# Void Linux
xbps-install -S glow

echo "deb [signed-by=/etc/apt/keyrings/charm.gpg] https://repo.charm.sh/apt/ * *" | sudo tee /etc/apt/sources.list.d/charm.list

enabled=1
gpgcheck=1
gpgkey=https://repo.charm.sh/yum/gpg.key' | sudo tee /etc/yum.repos.d/charm.repo
sudo yum install glow

Or download a binary from the releases page. MacOS, Linux, Windows, FreeBSD and OpenBSD binaries are available, as well as Debian, RPM, and Alpine packages. ARM builds are also available for macOS, Linux, FreeBSD and OpenBSD.

Go

Or just install it with go:

go install github.com/charmbracelet/glow/v2@latest

Build (requires Go 1.21+)

git clone https://github.com/charmbracelet/glow.git
cd glow
go build

The TUI

Simply run glow without arguments to start the textual user interface and browse local. Glow will find local markdown files in the current directory and below or, if you’re in a Git repository, Glow will search the repo.

Markdown files can be read with Glow's high-performance pager. Most of the keystrokes you know from less are the same, but you can press ? to list the hotkeys.

The CLI

In addition to a TUI, Glow has a CLI for working with Markdown. To format a document use a markdown source as the primary argument:

# Read from file
glow README.md

# Read from stdin
echo "[Glow](https://github.com/charmbracelet/glow)" | glow -

# Fetch README from GitHub / GitLab
glow github.com/charmbracelet/glow

# Fetch markdown from HTTP
glow https://host.tld/file.md

Word Wrapping

The -w flag lets you set a maximum width at which the output will be wrapped:

glow -w 60

Paging

CLI output can be displayed in your preferred pager with the -p flag. This defaults to the ANSI-aware less -r if $PAGER is not explicitly set.

Styles

You can choose a style with the -s flag. When no flag is provided glow tries to detect your terminal's current background color and automatically picks either the dark or the light style for you.

glow -s [dark|light]

Alternatively you can also supply a custom JSON stylesheet:

glow -s mystyle.json

For additional usage details see:

glow --help

Check out the Glamour Style Section to find more styles. Or make your own!

The Config File

If you find yourself supplying the same flags to glow all the time, it's probably a good idea to create a config file. Run glow config, which will open it in your favorite $EDITOR. Alternatively you can manually put a file named glow.yml in the default config path of you platform. If you're not sure where that is, please refer to glow --help.

Here's an example config:

# style name or JSON path (default "auto")
style: "light"
# mouse wheel support (TUI-mode only)
mouse: true
# use pager to display markdown
pager: true
# at which column should we word wrap?
width: 80
# show all files, including hidden and ignored.
all: false
# show line numbers (TUI-mode only)
showLineNumbers: false
# preserve newlines in the output
preserveNewLines: false
