Iota is a terminal-based text-editor written in Rust.
Here's what it looks like right now, editing itself.
Iota was born out of my frustrations with existing text editors. Over the years I've tried combinations of simple text editors, IDEs and everything in between. None of them felt right to me, however. Some were too slow & bulky, others were too difficult to customise and still others were platform specific and I couldn't use them on all my machines.
I started building Iota with the view of combining ideas and features from serveral different editors while designing it to work on modern hardware.
Why Rust? Because its fun and why not!
The goals for Iota are that it would be:
- 100% open source
- highly extensible/customisable/scriptable
- fast & efficient - designed with modern hardware in mind
- cross platform - it should work anywhere
- developer friendly - it should just "get out of the way"
- Rust tooling integration (see note below)
Iota is still in the very early stages, and is probably not ready for every day use. Right now the focus is on implementing and polishing the basic editing functionality.
Windows support is coming, but it's somewhat slow right now. Help with this would be greatly appreciated!
Note on Rust integration: The aim is to support code editing in all languages (and of course plain text), with a lean towards Rust and integration with Rust tools. I don't intend it to be a "Rust IDE" or "Rust only", however I think it would be cool to experiment with integration with Rust tooling. This could also be applied to other languages too.
Clone the project and run
cargo build --release.
NOTE: Iota needs to be built using the nightly toolchain for now, not 1.0.0. Multirust is very useful for managing multiple rust versions.
Then to start the editor run
./target/release/iota /path/to/file.txt. Or
./target/release/iota to open an empty buffer.
You can also create buffers from
# open a buffer with the output of `ifconfig` ifconfig | ./target/release/iota
You can move the cursor around with the arrow keys.
To save, press
To exit, press
Iota currently supports both Vi and Emacs style keybindings for simple movement.
You can enable Vi style keybindings by using the
--vi flag when starting Iota.
The vi-style modes are in the early stages, and not all functionality is there
just yet. The following works:
- while in normal mode:
wmove one word forward
bmove one word backward
0move to start of line
$move to end of line
- while in insert mode:
Alternatively, you can use the following emacs-style keys:
Ctrl-amove to start of line
Ctrl-emove to end of line
