dragon consists of 2 main components:

  • A packaging system
  • A ninja buildfile generator

It uses Theos components for logos processing, but does not require an existing theos installation.



Requires python3


pip install dragon


Dragon projects are configured via a single DragonMake file, regardless of how many subprojects you have.

You can specify subprojects and their information here. This allows for compiling slices in parallel easily, along with keeping things much more organized.

DragonMake Syntax

DragonMake follows fairly standard YAML syntax, with a singular escape character, $.

For single line variables, you can use bash syntax to evaluate a command with $$(command args)

A single $ denotes a ninja variable. For using bash syntax in variables, one can use $$ to represent a $ . For example, one could use $$PWD to get the value of an environment variable in a command.

Using the below items will parse output through xargs and add entries to the list the item is in: $wildcard("directory", "*.extension") will find all files in a specific directory.

$eval("bash command") is also provided, in the event more complex manipulation is needed.

Example Project

This should serve as a guideline for how a project should be laid out. You can declare as many projects as you want, it's all going to be crammed into the same deb.

Note: You dont need to create a control file if the relevant info is included in this one.


# 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

    type: tweak
        - "*.xm"
# Now for preferences!
    dir: nameprefs
    type: prefs
        - BlahRootListController.m
        - ACellYouUse.m
        - ../SomeFileFromYourMainTweak.m
# Subproject example
    dir: othertweak
    type: tweak
        - Tweak.xm

DragonMake Variables

Please pay attention to the provided example to understand how these should be laid out in a file.

type str Type of project being built. One of "tweak"/"bundle"/"library". N/A
logos_files list List of files that require the logos preprocessor []
files list List of files to be compiled, excluding logos files. []

sysroot str Root of the Patched SDK to build with $DRAGONBUILD/sdks/iPhoneOS.sdk
cc str c/c++ compiler to use clang+
ld str linker to use clang+
ldid str ldid binary to sign with ldid
dsym str dsymutil binary to symbolicate with dsymutil
logos str logos.pl file to use for preprocessing $DRAGONBUILD/bin/logos.pl
stage str/list Console command(s) to run before after build and before packaging
arc str -fobjc-arc, if enabling so is desired -fobjc-arc
targ str build target -DTARGET_IPHONE=1
warnings str Warnings flag -Wall
optim str Optimzation level. Higher levels can break obfuscators. 0
debug str debug flags -fcolor-diagnostics
libs list List of libraries to link the binary against
frameworks list List of Frameworks to compile with ['CoreFoundation', 'Foundation', 'UIKit', 'CoreGraphics', 'QuartzCore', 'CoreImage', 'AudioToolbox']
cflags str additional flags to pass to clang and the linker
ldflags str additional flags to pass to the linker
ldidflags str custom option for ldid '-S'
install_location str override variable for bundles/libraries to allow specifying install location
framework_search_dirs list Framework Search Dirs. Changing this variable overrides defaults. ['$sysroot/System/Library/Frameworks', '$sysroot/System/Library/PrivateFrameworks', '$dragondir/frameworks']
additional_framework_search_dirs list Allows adding framework search dirs without overwriting old ones. []
library_search_dirs list Library search dirs. Just like the framework search ['$dragondir/lib', '.']
additional_library_search_dirs list Add to lib search without overwriting []

Yaml parsing is done via python3.
