📦 Installation

To make PTerm available in your project, you can run the following command.
Make sure to run this command inside your project, when you're using go modules 😉

go get github.com/pterm/pterm

If you want to create a CLI tool, make sure to check out our cli-template, which features automatic website generation, automatic deployments, a custom CI-System and much more!

⭐ Main Features

Feature Description
🪀 Easy to use Our first priority is to keep PTerm as easy to use as possible.
With many examples for each individual component, getting started with PTerm is extremely easy.
All components are similar in design and implement interfaces to simplify mixing individual components together.
🤹‍♀️ Cross-Platform We take special precautions to ensure that PTerm works on as many operating systems and terminals as possible.
Whether it's Windows CMD, macOS iTerm2 or in the backend (for example inside a GitHub Action or other CI systems), PTerm guarantees beautiful output!
🧪 Well tested PTerm has a 100% test coverage, which means that every line of code inside PTerm gets tested automatically
We test PTerm continuously. However, since a human cannot test everything all the time, we have our own test system with which we currently run 28774automated tests to ensure that PTerm has no bugs.
✨ Consistent Colors PTerm uses the ANSI color scheme which is widely used by terminals to ensure consistent colors in different terminal themes.
If that's not enough, PTerm can be used to access the full RGB color scheme (16 million colors) in terminals that support TrueColor.
📚 Component system PTerm consists of many components, called Printers, which can be used individually or together to generate pretty console output.
🛠 Configurable PTerm can be used by without any configuration. However, you can easily configure each component with little code, so everyone has the freedom to design their own terminal output.
✏ Documentation To view the official documentation of the latest release, you can go to the automatically generated page of pkg.go.dev This documentation is very technical and includes every method that can be used in PTerm.
For an easy start we recommend that you take a look at the examples section. Here you can see pretty much every feature of PTerm with example code. The animations of the examples are automatically updated as soon as something changes in PTerm.

Types

type Area added in v0.12.47 

type Area struct {
	Term Terminal
	// contains filtered or unexported fields
}

Area displays content which can be updated on the fly. You can use this to create live output, charts, dropdowns, etc.

func NewArea added in v0.12.47 

func NewArea(term Terminal) Area

NewArea returns a new Area.

func (*Area) Clear added in v0.12.47 

func (area *Area) Clear()

Clear clears the content of the Area.

func (*Area) Update added in v0.12.47 

func (area *Area) Update(content string)

Update overwrites the content of the Area.

type AreaPrinter 

type AreaPrinter struct {
	Term           Terminal
	RemoveWhenDone bool
	Fullscreen     bool
	Center         bool
	// contains filtered or unexported fields
}

AreaPrinter prints an area which can be updated easily. use this printer for live output like charts, algorithm visualizations, simulations and even games.

func (*AreaPrinter) Clear 

func (p *AreaPrinter) Clear()

Wrapper function that clears the content of the Area. Moves the cursor to the bottom of the terminal, clears n lines upwards from the current position and moves the cursor again.

func (*AreaPrinter) GenericStart
