Fervor

Disclaimer: Changes to the veandco/go-sdl2 packages since the development of this software may have created problematic incompatibilities, which I do not plan to investigate anytime soon. If you would like to try Fervor, I recommend compiling against a veandco/go-sdl2 commit from September 2015.

A graphical, modeless, cross-platform text editor influenced by Acme, vi, and even Notepad. Features include:

• Infinite undo
• Unicode (UTF-8) support
• Regular expression search
• Acme-like right-click find
• No GUI toolkit dependencies
• Quick startup and low memory footprint
• Asynchronous shell command execution and selection filtering
• Basic syntax highlighting (currently for: Bash, C, CSS, Go, HTML, INI, JavaScript, JSON, Lua, Make, Python, Ruby, and SVG)

Not included:

• A scrollbar.
• Tabs or panes. Use a good window manager instead!

See also: TODO.md.

Installation

Install or update via the go command:

go get -u github.com/jangler/{edit,fervor}

Alternatively, download a binary distribution from https://github.com/jangler/fervor/releases.

In either case, the SDL2 and SDL2_ttf libraries are required.

Holding Shift makes a cursor motion select text from the previous cursor position to the resulting position. Enter, Backspace, Delete, Home, End, PgUp, PgDn, Up, Down, Left, Right, Esc, Ctrl+Backspace, Ctrl+Delete, Ctrl+Home, Ctrl+End, Ctrl+Left, and Ctrl+Right should also work as expected.

Mouse bindings

Left click   Position cursor
Left drag    Select text
Right click  Find next instance of clicked word or selection
Right drag   Find next instance of selection

Holding Shift makes a left click select text from the previous cursor position to the clicked position, and makes a right click or drag search backward instead of forward.
