Dragon

Overview

DragonBuild 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.

Setup

Prerequisites

Requires ninja, perl, and python3

python3 requires modules pyyaml.

Installation

bash <(curl -sL dr.krit.me)

Usage

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.

# 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

depends: mobilesubstrate, preferenceloader

TweakName:
    type: tweak
    files:
        - "*.xm"
        
# Now for preferences!
TweakNamePrefs:
    dir: nameprefs

DragonMake Variables

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

Name	Type	Description	Default
name	str	Name of the whole project	N/A
icmd	str	Command to run on device after install	sbreload
name	str	Name of the item being build. Specified as yourNameHere: with the rest of the item specific variables below	N/A
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.	[]
targetios	str	Minimum iOS Version Required	[]

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', '.']

Yaml parsing is done via python3.

DragonBuild Command Line Arguments

All of these can be combined and ran at the same time, if needed.

Building and Installing your Tweak

All of these arguments can be specified using only the first character (dragon c b i for example)

dragon build to build (dragon make also works)

dragon install to install.

dragon do combines both of these.

dragon release loads DragonRelease after loading DragonMake, allows for setting variables specific to release builds.

dragon clean performs a clean rebuild of the entire project and subprojects.

Generating compile commands for clangd or other tools

dragon export
