Key bindings

When working with a physical keyboard, you can use key bindings for performing various text actions. The editor provides support for some key bindings by default. However, you can subscribe to KeyBindingEvent and add your own key bindings. You can even override the default key bindings and perform actions of your own.

The currently supported key bindings are mostly similar to Android Studio/Intellij IDEA. See the supported key bindings.

Get started

Add to your app's dependencies:

dependencies {
    implementation(platform("io.github.Rosemoe.sora-editor:bom:<versionName>"))
    implementation("io.github.Rosemoe.sora-editor:<moduleName>")
}

Available modules:

• editor
  Widget library containing all basic things of the framework
• editor-lsp
  A convenient library for creating languages by using Language Server Protocol (aka LSP)
• language-java
  A simple implementation for Java highlighting and identifier auto-completion
• language-textmate
  An advanced highlighter for the editor. You can find textmate language bundles and themes and load them by using this module. The internal implementation of textmate is from tm4e.
• language-treesitter
  Offer tree-sitter support for editor. This can be used to parse the code to an AST fast and incrementally, which is helpful for accurate highlighting and providing completions. Note that this module only provides incremental paring and highlighting. Thanks to Java bindings android-tree-sitter
