A Swift CLI tool that generates complexity metrics information from a Cocoapods Xcode project or a SwiftPM package. Currently, that´s what you can do:
- Dependency graph (dot format)
- Cyclomatic complexity evaluation
- Number of dependant modules
- Compare stats between different branches
- Show stats along the git history
- Show dependant targets
You can read more information about dependency complexity in our Technical article "How to control your dependencies".

.build/release/jungle helpOVERVIEW: Displays historic complexity of the dependency graph
USAGE: jungle history [--since <since>] [--module <module>] --target <target> [--output-format <output-format>] [<directory-path>]
ARGUMENTS:
<directory-path> Path to the directory where Podfile.lock is located (default: .)
OPTIONS:
--since <since> Equivalent to git-log --since: Eg: '6 months ago' (default: 6 months ago)
--module <module> The Module to compare. If you specify something, target parameter will be ommited
--target <target> The target in your Podfile or Package.swift file to be used (this can be a Product name in SPM)
--output-format <output-format>
csv or json (default: csv)
--version Show the version.
-h, --help Show help information.Example:
jungle history --target App ProjectDirectory/ --since '1 week ago'

Now;Current;124;21063;;OVERVIEW: Compares the current complexity of the dependency graph to others versions in git
USAGE: jungle compare [--to <git-object> ...] [--module <module>] --target <target> [<directory-path>]
ARGUMENTS:
<directory-path> Path to the directory where Podfile.lock or Package.swift is located (default: .)
OPTIONS:
--to <git-object> The git objects to compare the current graph to. Eg: - 'main', 'my_branch', 'some_commit_hash'. (default: HEAD, main, master)
--module <module> The Module to compare. If you specify something, target parameter will be ommited
--target <target> The target in your Podfile or Package.swift file to be used (this can be a Product name in SPM)
--version Show the version.
-h, --help Show help information.Example:
jungle compare --target App ProjectDirectory/ --to main

OVERVIEW: Outputs the dependency graph in DOT format
USAGE: jungle graph [--of <git-object>] [--module <module>] --target <target> [--use-multiedge] [--show-externals] [<directory-path>]
ARGUMENTS:
<directory-path> Path to the directory where Podfile.lock or Package.swift is located (default: .)
OPTIONS:
--of <git-object> A git object representing the version to draw the graph for. Eg: - 'main', 'my_branch', 'some_commit_hash'.
