# Focus

A simple editor whose goal is to get out of your way and let you do work.

This editor is for people who value simplicity, are sensitive to input latency and do not require heavy language support in their editor.

## Quick start

Basic information can be found here https://focus-editor.dev/docs.html

NOTE: if you are on a newer macOS you may have to run `xattr -d com.apple.quarantine /Applications/Focus.app` in order to be able to run the editor, until we are able to sign the executable.

## How to compile

`$ jai first.jai - release`

(NOTE: it's `- release`, not `-release`)

Minimum Jai version: `0.2.029` (the language is currently in closed beta, but it will hopefully go into open beta soon)

**On macOS:**

1. Full XCode must be installed

2. To avoid multiple security warnings like [in these screenshots](https://github.com/focus-editor/focus/issues/6#issuecomment-1531240978):
> "freetype.dylib" cannot be opened because the developer cannot be verified. macOS cannot verify that this app is free from malware.

... run the following command:

`xattr -d -r com.apple.quarantine /path/to/your/jai/distribution`

3. Compile:

a. `/path/to/jai-macos first.jai - release`

or

b. `arch -x86_64 /path/to/jai-macos first.jai - release`

## Disclaimer

The editor is in beta. This means you may encounter some bugs here and there, and not all wrinkles have been ironed out yet.

## Limitations

- Only 64-bit systems are supported, Windows 8+, Linux (WIP), macOS (WIP).
- This editor is not designed for editing very large files (it is expected that editing might start lagging upwards of 100K LOC). 2GB files is a hard limit right now.
- Multi-codepoint Unicode symbols are not supported.
- Currently only RGB monitor panels are supported. If your text looks funny or blurry, please open an issue.

## Acknowledgements

- The editor was made possible by the fantastic Jai programming language by [Jonathan Blow](https://en.wikipedia.org/wiki/Jonathan_Blow).

- The editor was inspired by [Jamie Brandon's blog post](https://www.scattered-thoughts.net/writing/focus-intro/). Nothing other than the name was borrowed from his editor - the name was just too good.

- I am very grateful to my wife who supported me along the way and took on the bigger share of the housework to let me work on the editor.

- A special thanks to the two early adopters who helped to make the editor more robust and more enjoyable to use: [@cookednick](https://github.com/cookednick) and [@ustance](https://github.com/ustance).

- The default font [FiraCode](https://github.com/tonsky/FiraCode) is created by [Nikita Prokopov](https://github.com/tonsky).

- Icons - [Font Awesome](http://fontawesome.io) by Dave Gandy.

- If not for VSCode's annoying "restart to apply the latest update" notifications every other day, this editor might never have been created.
