        # Gum



    

    



    

    

    



A tool for glamorous shell scripts. Leverage the power of

[Bubbles](https://github.com/charmbracelet/bubbles) and [Lip

Gloss](https://github.com/charmbracelet/lipgloss) in your scripts and aliases

without writing any Go code!



The above example is running from a single shell script ([source](./examples/demo.sh)).

## Tutorial

Gum provides highly configurable, ready-to-use utilities to help you write

useful shell scripts and dotfiles aliases with just a few lines of code.

Let's build a simple script to help you write

[Conventional Commits](https://www.conventionalcommits.org/en/v1.0.0/#summary)

for your dotfiles.

Ask for the commit type with gum choose:

```bash

gum choose "fix" "feat" "docs" "style" "refactor" "test" "chore" "revert"

```

> [!NOTE]

> This command itself will print to stdout which is not all that useful. To make use of the command later on you can save the stdout to a `$VARIABLE` or `file.txt`.

Prompt for the scope of these changes:

```bash

gum input --placeholder "scope"

```

Prompt for the summary and description of changes:

```bash

gum input --value "$TYPE$SCOPE: " --placeholder "Summary of this change"

gum write --placeholder "Details of this change"

```

Confirm before committing:

```bash

gum confirm "Commit changes?" && git commit -m "$SUMMARY" -m "$DESCRIPTION"

```

Check out the [complete example](https://github.com/charmbracelet/gum/blob/main/examples/commit.sh) for combining these commands in a single script.

## Customization

You can customize `gum` options and styles with `--flags` and `$ENVIRONMENT_VARIABLES`.

See `gum  --help` for a full view of each command's customization and configuration options.

Customize with `--flags`:

```bash

gum input --cursor.foreground "#FF0" \

          --prompt.foreground "#0FF" \

          --placeholder "What's up?" \

          --prompt "* " \

          --width 80 \

          --value "Not much, hby?"

```

Customize with `ENVIRONMENT_VARIABLES`:

```bash

export GUM_INPUT_CURSOR_FOREGROUND="#FF0"

export GUM_INPUT_PROMPT_FOREGROUND="#0FF"

export GUM_INPUT_PLACEHOLDER="What's up?"

export GUM_INPUT_PROMPT="* "

export GUM_INPUT_WIDTH=80

# --flags can override values set with environment

gum input

```



## Input

Prompt for input with a simple command.

```bash

gum input > answer.txt

gum input --password > password.txt

```



## Write

Prompt for some multi-line text (`ctrl+d` to complete text entry).

```bash

gum write > story.txt

```



## Filter

Filter a list of values with fuzzy matching:

```bash

echo Strawberry >> flavors.txt

echo Banana >> flavors.txt

echo Cherry >> flavors.txt

gum filter < flavors.txt > selection.txt

```



Select multiple options with the `--limit` flag or `--no-limit` flag. Use `tab` or `ctrl+space` to select, `enter` to confirm.

```bash

cat flavors.txt | gum filter --limit 2

cat flavors.txt | gum filter --no-limit

```

## Choose

Choose an option from a list of choices.

```bash

echo "Pick a card, any card..."

CARD=$(gum choose --height 15 {{A,K,Q,J},{10..2}}" "{♠,♥,♣,♦})

echo "Was your card the $CARD?"

```

You can also select multiple items with the `--limit` or `--no-limit` flag, which determines

the maximum of items that can be chosen.

```bash

cat songs.txt | gum choose --limit 5

cat foods.txt | gum choose --no-limit --header "Grocery Shopping"

```



## Confirm

Confirm whether to perform an action. Exits with code `0` (affirmative) or `1`

(negative) depending on selection.

```bash

gum confirm && rm file.txt || echo "File not removed"

```



## File

Prompt the user to select a file from the file tree.

```bash

EDITOR $(gum file $HOME)

```



## Pager

Scroll through a long document with line numbers and a fully customizable viewport.

```bash

gum pager < README.md

```



## Spin

Display a spinner while running a script or command. The spinner will

automatically stop after the given command exits.

To view or pipe the command's output, use the `--show-output` flag.

```bash

gum spin --spinner dot --title "Buying Bubble Gum..." -- sleep 5

```



Available spinner types include: `line`, `dot`, `minidot`, `jump`, `pulse`, `points`, `globe`, `moon`, `monkey`, `meter`, `hamburger`.

## Table

Select a row from some tabular data.

```bash

gum table < flavors.csv | cut -d ',' -f 1

```

## Style

Pretty print any string with any layout with one command.

```bash

gum style \

	--foreground 212 --border-foreground 212 --border double \

	--align center --width 50 --margin "1 2" --padding "2 4" \

	'Bubble Gum (1¢)' 'So sweet and so fresh!'

```



## Join

Combine text vertically or horizontally. Use this command with `gum style` to

build layouts and pretty output.

Tip: Always wrap the output of `gum style` in quotes to preserve newlines

(`\n`) when using it as an argument in the `join` command.

```bash

I=$(gum style --padding "1 5" --border double --border-foreground 212 "I")

LOVE=$(gum style --padding "1 4" --border double --border-foreground 57 "LOVE")

BUBBLE=$(gum style --padding "1 8" --border double --border-foreground 255 "Bubble")

GUM=$(gum style --padding "1 5" --border double --border-foreground 240 "Gum")

I_LOVE=$(gum join "$I" "$LOVE")

BUBBLE_GUM=$(gum join "$BUBBLE" "$GUM")

gum join --align center --vertical "$I_LOVE" "$BUBBLE_GUM"

```



## Format

`format` processes and formats bodies of text. `gum format` can parse markdown,

template strings, and named emojis.

```bash

# Format some markdown

gum format -- "# Gum Formats" "- Markdown" "- Code" "- Template" "- Emoji"

echo "# Gum Formats\n- Markdown\n- Code\n- Template\n- Emoji" | gum format

# Syntax highlight some code

cat main.go | gum format -t code

# Render text any way you want with templates

echo '{{ Bold "Tasty" }} {{ Italic "Bubble" }} {{ Color "99" "0" " Gum " }}' \

    | gum format -t template

# Display your favorite emojis!

echo 'I :heart: Bubble Gum :candy:' | gum format -t emoji

```

For more information on template helpers, see the [Termenv

docs](https://github.com/muesli/termenv#template-helpers). For a full list of

named emojis see the [GitHub API](https://api.github.com/emojis).



## Log

`log` logs messages to the terminal at using different levels and styling using

the [`charmbracelet/log`](https://github.com/charmbracelet/log) library.

```bash

# Log some debug information.

gum log --structured --level debug "Creating file..." name file.txt

# DEBUG Unable to create file. name=temp.txt

# Log some error.

gum log --structured --level error "Unable to create file." name file.txt

# ERROR Unable to create file. name=temp.txt

# Include a timestamp.

gum log --time rfc822 --level error "Unable to create file."

```

See the Go [`time` package](https://pkg.go.dev/time#pkg-constants) for acceptable `--time` formats.

See [`charmbracelet/log`](https://github.com/charmbracelet/log) for more usage.
