dragon aims to be a full environment for development and research on Apple devices.
In your terminal:
bash <(curl -sL dr.krit.me)
dragon update will update dragon to the latest commit. Run this before filing an issue.
This readme needs work and doesn't come close to covering the scope of the project.
dragon -h includes a list of available supported stable features on the current build.
Reaching out to me on #development on the r/jb discord server is reccomended if you're having issues with anything.
dragon supports theos projects alongside it's own, powerful, expandable format.
A good majority of projects built with Theos will build out of the box with dragon.
If your Theos project fails to build, file an issue with a link to it. This is insanely helpful when it comes to improving the interpreter.
DragonMake is a YAML-based format that represents an entire project and all subprojects within a single file.
It was created with the goal of being writable by hand, without the help of a "New Instance Creator". Dragon's NIC is being worked on; It is however, lightly on hold, so as not to encourage new users to leap into this project just yet.
DragonMake can also optionally hold the control, preinst, postinst, etc. file values inside itself instead of requiring manually creating them
Regardless of folder layout, there are no "subprojects" in dragon. Instead, you have a single "Project", which then has "Modules" (your tweak, your prefs, etc).
This format makes working with complex projects much easier, and keeps things incredibly organized without limiting your freedom.
See the example below to get an idea
This should serve as a guideline for how a project should be laid out. You can declare as many modules as you want within your project.
"ModuleName" represents a module, here. Typically this is "TweakName" or "TweakNamePrefs", or something along those lines.
---
# This represents the overall project name.
# Everything in here will be built into a .deb package for installation
# Replace TweakName with the name of your project, of course
name: TweakName
icmd: killall -9 SpringBoard
id: com.mycompany.tweakname
version: 1.3
author: kritanta
depends: mobilesubstrate, preferenceloader
TweakName:
type: tweak
files:
- "*.xm"
# Now for preferences!
TweakNamePrefs:
dir: nameprefs
type: prefs
files:
- BlahRootListController.m
- ACellYouUse.m
- ../SomeFileFromYourMainTweak.m
# Subproject example
ASubTweakName:
dir: othertweak
type: tweak
files:
- Tweak.xm Variables within the DragonMake can be referenced via $varname
Environment Variables can be referenced with $$varname
You can evaluate a command in a subshell via $$(command args)
While these are all great for weird hacks, they're heavily not-reccomended. Run bash logic in the stage: section.
Wildcards:
"*.<x>" is the syntax. ** and other globbing rules are applied.
Type ls <your wildcard here> to get an idea.

dragon s (setup). This is ran automatically if one isn't yet configured.
When installing to a phone, if passwordless-authentication hasn't been configured, dragon will optionally configure it for you.
Run dragon s but leave the "IP" field empty. It will then use iproxy to install the package over usb.
dragon rs
dragon dr <command here> - Anything after dr is ran on device.
dragon dr with no further arguments will open an ssh session.
Dragon is available for iOS on https://repo.krit.me/. It can also be installed via CLI like a normal package.
dragon will autodetect if it's running on a phone.
If so, the install flag will install it to the current device and respring it.
