 # Relibre
 **Music release one-page generator**
 
-Relibre is a simple, free and open source landing page generator that is an alternative to services such as HyperFollow. Relibre has one job- giving the artist the ability to generate a single html file to self-host with their own methods.
+Relibre is a simple, free, and open-source landing-page generator—an alternative to HyperFollow—that produces a **single self-contained HTML file** you can host anywhere.
+
+**Try the generator →** [`https://relibre.site`](https://circlewithadot.net/relibre)
+
+---
+
+## What you get
+- A clean, responsive, single-file HTML page for a release
+- No trackers, no analytics
+- Host it anywhere (Neocities, object storage, GitHub/Gitea Pages, your own server, IPFS, etc.)
+- Optional native desktop app (AUR or source build, Flatpak soon)
 
 
-**Try the generator →** [`https://`](https://relibre.site)
+---
 
+## Source build
+```
+make deps
+make build
+```
+
+---
+
+## Arch Linux (AUR)
+
+```
+makepkg -si
+```

+
+This sample hook safeguards topic branches that have been
+published from being rewound.
+
+The workflow assumed here is:
+
+ * Once a topic branch forks from "master", "master" is never
+   merged into it again (either directly or indirectly).
+
+ * Once a topic branch is fully cooked and merged into "master",
+   it is deleted.  If you need to build on top of it to correct
+   earlier mistakes, a new topic branch is created by forking at
+   the tip of the "master".  This is not strictly necessary, but
+   it makes it easier to keep your history simple.
+
+ * Whenever you need to test or publish your changes to topic
+   branches, merge them into "next" branch.
+
+The script, being an example, hardcodes the publish branch name
+to be "next", but it is trivial to make it configurable via
+$GIT_DIR/config mechanism.
+
+With this workflow, you would want to know:
+
+(1) ... if a topic branch has ever been merged to "next".  Young
+    topic branches can have stupid mistakes you would rather
+    clean up before publishing, and things that have not been
+    merged into other branches can be easily rebased without
+    affecting other people.  But once it is published, you would
+    not want to rewind it.
+
+(2) ... if a topic branch has been fully merged to "master".
+    Then you can delete it.  More importantly, you should not
+    build on top of it -- other people may already want to
+    change things related to the topic as patches against your
+    "master", so if you need further changes, it is better to
+    fork the topic (perhaps with the same name) afresh from the
+    tip of "master".
+
+Let's look at this example:
+
+		   o---o---o---o---o---o---o---o---o---o "next"
+		  /       /           /           /
+		 /   a---a---b A     /           /
+		/   /               /           /
+	       /   /   c---c---c---c B         /
+	      /   /   /             \         /
+	     /   /   /   b---b C     \       /
+	    /   /   /   /             \     /
+    ---o---o---o---o---o---o---o---o---o---o---o "master"
+
+
+A, B and C are topic branches.
+
+ * A has one fix since it was merged up to "next".
+
+ * B has finished.  It has been fully merged up to "master" and "next",
+   and is ready to be deleted.
+
+ * C has not merged to "next" at all.
+
+We would want to allow C to be rebased, refuse A, and encourage
+B to be deleted.
+
+To compute (1):
+
+	git rev-list ^master ^topic next
+	git rev-list ^master        next
+
+	if these match, topic has not merged in next at all.
+
+To compute (2):
+
+	git rev-list master..topic
+
+	if this is empty, it is fully merged to "master".

+# Changelog
+
+### Migrating from v0.1.1 to v0.10.0
+
+1. `Webview.Open()` has been removed. Use other webview APIs to create a window, open a link and run main UI loop.
+2. `Webview.Debug()` and `webview.Debugf()` have been removed. Use your favorite logging library to debug webview apps.
+3. `Webview.Settings` struct has been removed. Title, URL and size are controlled via other API setters and can be updated at any time, not only when webview is created.
+4. `Webview.Loop()` has been removed. Use `Run()` instead.
+5. `WebView.Run()`, `WebView.Terminate()`, `WebView.SetTitle()`, `WebView.Dispatch()` stayed the same.
+6. `WebView.Exit()` has been renamed to `WebView.Destroy()`
+7. `WebView.SetColor()` and `WebView.SetFullScreen()` have been removed. Use `Window()` to get native window handle and probably write some Cgo code to adjust native window to your taste.
+8. `Webview.Dialog` has been removed. But it is likely to be brought back as a standalone module.
+9. `WebView.Eval()` remained the same.
+10. `WebView.InjectCSS()` has been removed. Use eval to inject style tag with CSS inside.
+11. `WebView.Bind()` kept the name, but changed the semantics. Only functions can be bound. Not the structs, like in Lorca.

+# webview_go
+
+[![GoDoc](https://godoc.org/github.com/webview/webview_go?status.svg)](https://godoc.org/github.com/webview/webview_go)
+[![Go Report Card](https://goreportcard.com/badge/github.com/webview/webview_go)](https://goreportcard.com/report/github.com/webview/webview_go)
+
+Go language binding for the [webview library][webview].
+
+> [!NOTE]
+> Versions <= 0.1.1 are available in the [old repository][webview].
+
+### Getting Started
+
+See [Go package documentation][go-docs] for the Go API documentation, or simply read the source code.
+
+Start with creating a new directory structure for your project.
+
+```sh
+mkdir my-project && cd my-project
+```
+
+Create a new Go module.
+
+```sh
+go mod init example.com/app
+```
+
+Save one of the example programs into your project directory.
+
+```sh
+curl -sSLo main.go "https://raw.githubusercontent.com/webview/webview_go/master/examples/basic/main.go"
+```
+
+Install dependencies.
+
+```sh
+go get github.com/webview/webview_go
+```
+
+Build the example. On Windows, add `-ldflags="-H windowsgui"` to the command line.
+
+```sh
+go build
+```
+
+### Notes
+
+Calling `Eval()` or `Dispatch()` before `Run()` does not work because the webview instance has only been configured and not yet started.
