# Gum
|
||
|
||
Gum is a collection of command-line utilities that make your shell scripts a
|
||
little more glamorous. It gives you the power of
|
||
[Bubbles](https://github.com/charmbracelet/bubbles) and
|
||
[Lip Gloss](https://github.com/charmbracelet/lipgloss) without needing to write
|
||
any Go code.
|
||
|
||
The following example is running from a [single Bash script](./examples/demo.sh).

|
||
## Installation
|
||
|
||
Use a package manager:
|
||
|
||
```bash

|
||

|
||
sudo apt update && sudo apt install gum

||
|
||

|
||
enabled=1
|
||
gpgcheck=0' | sudo tee /etc/yum.repos.d/charm.repo
|
||
sudo yum install gum
|
||
```
|
||
|
||
Or download it:
|
||
|
||
* [Packages][releases] are available in Debian and RPM formats
|
||

|
||
|
||
Or just install it with `go`:
|
||
|
||
```bash
|
||

|
||
```
|
||
|
||
[releases]: https://github.com/charmbracelet/gum/releases
|
||
|
||
## Interaction
|
||
|
||
#### Input
|
||
Prompt your users for input with a simple command.
|
||
|
||
```bash
|
||
gum input > answer.text
|
||
```
|
||
|
||
#### Write
|
||
|
||
Prompt your users to write some multi-line text.
|
||
|
||
```bash
|
||
gum write > story.text
|
||
```
|
||
|
||
#### Search
|
||
|
||
Allow your users to filter through a list of options by fuzzy searching.
|
||
|
||
```bash
|
||
echo Strawberry >> flavors.text
|
||
echo Banana >> flavors.text
|
||
echo Cherry >> flavors.text
|
||
cat flavors.text | gum search > selection.text
|
||
```
|
||
|
||
#### Progress
|
||
|
||
Display a progress bar while loading. The following command will display a
|
||
progress bar and increment the progress by 10% every 1 second. Thus, taking 10
|
||
seconds to complete the progress bar.
|
||
|
||
```bash
|
||
gum progress --increment 0.1 --interval 1s
|
||
```
|
||
|
||
#### Spinners
|
||
|
||
Display a spinner while taking some running action. We specify the command to
|
||
run while showing the spinner, the spinner will automatically stop after the
|
||
command exits.
|
||
|
||
```bash
|
||
gum spin --spinner dot --title "Buying Bubble Gum..." -- sleep 5
|
||
```
|
||
|
||
## Styling and Layout
|
||
|
||
#### Style
|
||
Pretty print any string with any layout with one command.
|
||
|
||
```bash
|
||
gum style \
|
||
--foreground "#FF06B7" --border "double" --align "center" \
|
||
--width 50 --margin "1 2" --padding "2 4" \
|
||
"Bubble Gum (1¢)" "So sweet and so fresh\!"
|
||
```
|
||
|
||
```
|
||
|
||
╔══════════════════════════════════════════════════╗
|
||
║ ║
|
||
║ ║
|
||
║ Bubble Gum (1¢) ║
|
||
║ So sweet and so fresh! ║
|
||
║ ║
|
||
║ ║
|
||
╚══════════════════════════════════════════════════╝
|
||
|
||
```
|
||
|
||
#### Join
|
||
|
||
Combine text vertically or horizontally with a single command, use this command
|
||
with `gum style` to build layouts and pretty output.
|
||
|
||
Note: It's important to wrap the output of `gum style` in quotes to ensure new
|
||
lines (`\n`) are part of a single argument passed to the `join` command.
|
||
|
||
```bash
|
||
I=$(gum style --padding "1 5" --border double "I")
|
||
LOVE=$(gum style --padding "1 4" --border double "LOVE")
|
||
BUBBLE=$(gum style --padding "1 8" --border double "Bubble")
|
||
GUM=$(gum style --padding "1 5" --border double "Gum")
|
||
|
||
I_LOVE=$(gum join "$I" "$LOVE")
|
||
BUBBLE_GUM=$(gum join "$BUBBLE" "$GUM")
|
||
gum join --align center --vertical "$I_LOVE" "$BUBBLE_GUM"
|
||
```
|
||
|
||
```

||
