Kodex is an advanced code editor which brings powerful and desktop-class editor features to your iPad or iPhone:

* Multi-caret editing, to quickly transform code selections.
* Regex search and replace, with template matching.
* Minimap which allows quick scroll navigation though the document.
* Syntax highlighting for over 150 languages.
* Auto complete feature (currently only for HTML).
* Add as many guide columns as you wish (default 80 and 120 characters).
* Configurable tab size (default 4 spaces), or insert spaces when pressing tab.
* Draw hints for invisible characters such as new lines, tabs, and spaces.
* Customizable key bindings, so you can configure Kodex to use the same key combos you are already used to.
* Light and Dark modes.

Kodex is integrated with the Files app, so you can easily open files from any other app, and from your iCloud documents folder.

You can launch Kodex QuickEdit from any file sharing view in any app to edit its contents without launching the main Kodex App (be aware this functionality depends on the host app implementing the sharing activity properly).

Included are 10 editor themes, and several monospaced fonts for code editing (you can install your own preferred fonts using system profiles). Font size and line spacing are adjustable, so you can configure Kodex to best fit your preferred screen size, arrangement, and orientation.

Kodex is not a compiler, and you can not build or run the code you edit from it. Think of Kodex as a NotePad++ or Sublime Text substitute for iPhone and iPad.

Kodex is currently optimized for external keyboards, such as Apple's Smart Keyboard for the iPad Pro, or any bluetooth/USB keyboard. More virtual keyboard features will be added in a future version.

What’s New

Version 1.3

This update brings some fixes:

* Minimap now works reliably on iOS 13
* Fix theming issues on iOS 13
* Fix search bar changing to a broken size and placement when switching apps

After many requests by several users, a Tip Jar has been added to Kodex. Tipping is not mandatory for continued usage of Kodex and will not unlock any new features.

Amazing app

Absolutely loved the app. Have a few suggestions for improvements. It will be nice to have a view only mode and disable the keyboard. Also please bring full screen mode. Finally the ability to click on a function and the app gives the definition or hints would make this app a killer!

Wish I knew about this sooner

Super awesome text editing app. Syntax highlight! Capable of opening any files! And there's theme list. I love any of the darkish purple, blue, and green text editor themes and then there's Solarized Dark. Jackpot!! Beyond text editor, I tend to think that the simple choice between white and dark themes to be boring. Too boring. A white theme with blue accent is terribly boring. I'm glad this app at least offers other accent colors. The dark theme with purple accent looks nice.

I've uninstalled Documents 6 for this. That app used to be awesome until Files app introduced in iOS 11 and this app is the last missing puzzle piece I need to read and edit text files.

I had to drop one star for the following reasons:
ꊱ1 No alternative language keyboards. I use Japanese Romaji and Emoji.

ꊱ2 The Text Replacement isn't working very well.

ꊱ3 The height spacing looks weird (in Courier Regular) when there's unicode characters.

ꊱ4 Following text after pasted (unicode?) text can sometime be in different font other than Courier Regular.

I'd sacrifice syntax highlights, height spacing, or so in favor of keyboard honestly, if that's the root of problems. Quality text editor should be able to read and edit .txt and other text-based files without issues.

Ongoing Stability Issues

To provide as much system information as possible, these experiences are from a user using a 2018 iPad Pro 12.9 with a Bluetooth keyboard. The Bluetooth keyboard is a Logitech K811.

I have used this application for about 9 months exclusively via an external keyboard. I have observed some instances of crashing while holding down the backspace key, but these instances have drastically increased with iPadOS. Either much less time holding down the backspace key is needed for a crash or some other keystroke-related action is causing a crash. Beyond that, this is a very intuitive editor which has the syntaxes, character formatting, etc. for my needs, and a lot of the features have transitioned successfully to iPadOS.
