# GoBorderless

GoBorderless is a modern, open-source Windows application that allows users to easily manage and toggle borderless windowed mode for any application (especially useful for games that have poor alt-tabbing support). Initially created as a clone of [NoMoreBorder](https://github.com/invcble/NoMoreBorder) for the purpose of learning Go, GoBorderless now offers a clean UI, streamlined user experience, and additional features.

## Features

- 🪟 **Make Any Window Borderless**  
  Instantly remove window borders from any running application with a single click.

- 🔍 **Automatic Window Detection**  
  Automatically lists currently open windows with their titles and executable paths.

- 🖱️ **One-Click Control**  
  Select a window from the list and toggle borderless mode effortlessly.

- 🧠 **Smart Positioning**  
  Remembers your last settings and positions for each app.

- ⚙️ **Lightweight & Portable**  
  No installer needed. Just download and run the portable executable.

- 🛠️ **Written in Go with Fyne**  
  Clean, fast, and cross-platform capable core built using the [Fyne](https://fyne.io/) GUI toolkit.

## Instructions
1. Click `+ Create New app Config`
2. Select your application from the dropdown. This list is filtered to only show windowed applications. If your application is not showing up, make sure it is not fullscreen or otherwise missing window decoration. If you still cannot get it to show up, please create an [Issue](https://github.com/adamk33n3r/GoBorderless/issues/new) and we can look into it.
3. Fill out any settings you wish to set like match type, position, and size.
4. Click Create
5. Your application config will now be in the list and you can apply, restore, or turn on auto-apply (will check to apply the borderless settings once a second)

## Download

You can find the latest portable `.exe` files in the [releases](https://github.com/adamk33n3r/GoBorderless/releases) section.

## Build from Source

To build GoBorderless yourself:

```sh
go install fyne.io/tools/cmd/fyne@latest # currently need https://github.com/adamk33n3r/fyne-tools for correct icon support unless merged upstream
fyne package --release
```

## Development

GoBorderless is written in Go using the [Fyne](https://fyne.io/) framework.

I use [air](https://github.com/air-verse/air) to live-reload the app as I make changes. You can install it using the following command:
```sh
go install github.com/air-verse/air@latest
```
And then just run
```sh
air
```
to start it. It uses the `.air.toml` file in the repository by default.

Otherwise a simple `go run .` should work.
