Code Colors
**Code Colors - Quicklook Preview** is a free, very fast Quicklook Extension for macOS.
It is different than others because it uses new SwiftUI Text capabilities: no html, no rtf, no js.
Very fast as in _breaks the sound barrier_: it's opened before the sound of your spacebar/click ends. [`*`](https://github.com/Oil3/CodeColors-Quicklook-Syntax-Highlighting/tree/oil3#sound-on-truth-of-breaking-the-sound-barrier)
### Features
- **Any File Types**: More than 60 extensions, such as `.swift`, `.py`, `.yaml`, `.xml`, `.json`, `.c`, `.h`, `.mm`, `.1`, `.gradle`... etc, as well as files without extension. But not Markdown. [Info.plit full list](https://github.com/Oil3/CodeColors-Quicklook-Syntax-Highlighting/blob/oil3/QuickCodeColorLook/Info.plist).
- **Syntax Highlighting**: Still basic.
- **Lazy Loading**: Loads lines per 96KB chunks for immediate viewing, stops when view disappears.
- **Pure Swift**: 100% Swift with only the code that is necessary: the minimum and nothing external.
- **Main-Thread Offloading**: All file loading and processing are done off the main thread, safeguarding against system freezes.
- **As safe as your file**: Sandboxed, hardened, notarized, doesn't require internet or any permission whatsoever, doesn't run the files, but applies formatting on strings that match a pattern.
- **No File Associations**: Doesn't replace the default app for opening files, doesn't interfere with workflow.
### Download from Releases or from the repository
Direct download latest [Universal binary (Silicon and Intel)](https://github.com/Oil3/CodeColors-Quicklook-Syntax-Highlighting/releases/download/LatestFeb2025UniversalBinary/CodeColors.2025Feb.Universal.Binary.zip).
## Install
>Launch the app once. This registers the extension as the extension itself stays within the app bundle.
## Uninstall
>Delete the app.
## Update
>Replace the older app with the newer app. MacOS looks for the extension in the app: if app is moved, a relaunch might be needed.
### Issues/todo:
The first priority _was_ to handle a _test file with 23millions characters in 200thousands lines_, with immediate render, no freeze and a quick memory release.
Now the needs are:
- Implementing the logic for customizing the colors which is God willing for next update; right now these are just my colors.
- Fixing an issue where a negative number doesn't have its `-` sign colored.
- import profiles
- Markdown is not in the list to not interfere until we have the settings to choose which extension to ignore.
