editor

A cross platform low-level code editor

Frontend

This editor is a frontend for xi-editor

Features

• Multi-platform windowing and input using winit.
• Vulkan rendering using vulkano.
• Widget system for rendering queue, currently implemented:
  • primitive widgets (coloured quads)
  • text widget for glyph rendering (currently using glyph-brush
  • edit view is a widget (containing many internal widgets).
• Line numbers & gutter (Currently toggle with F5)
• Themes (Currently bound to F1, F2, and F3)
• Syntax highlighting
• Vim key bindings (more advanced keystrokes still a work in progress)

Key Bindings (Vim)

Currently only basic bindings have been made, but the plan is to implement most of the main keybindings, will unlikely support vimscript. Bindings are written using rust macros, below is an example:

See more at src/events/bindings.rs

...
bindings.extend(bindings!(
  Keybinding;
  
  F1; Action::SetTheme(String::from("Solarized (dark)"));
  F5; Action::ToggleLineNumbers;
  PageUp, ~Mode::Command; motion!(Motion Up by Page);
  Return, +Mode::Normal; motion!(Motion Down), motion!(Motion FirstOccupied);
  Delete, +Mode::Insert; motion!(Delete Right);
  ...
));

As you can see, the beginning of each key binding starts with the key trigger (ie. a function key, a letter etc.) You can specify conditions, such as requiring a single mode with + to be active, or any other mode other then the one specified with ~. This is followed by an Action, and other macros exist such as motion to make life a little easier without chaining a bunch of nested rust enumerables together.

Preferences

As this is a frontend for Xi-Editor, preferences can be stored at $HOME/.config/xi/preferences.xiconfig in toml format. Here is an example:

font_size = 14
tab_size = 2
translate_tabs_to_spaces = true

Plans (Likely to change...)

• Implement multi-view handling
• Implement LSP plugin
• Mouse interaction?
• In-built LISP-like language to define keymapping to actions. Useful for complex key-bindings like VIM, still in the ideation phase...
