Jungle

Swift

A Swift CLI tool that generates complexity metrics information from a Cocoapods Xcode project or a SwiftPM package. Currently, thatยดs 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".

Usage

Fetch Historic Complexities

OVERVIEW: 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'

Compare Complexity Graphs

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
[
  {
    "modules" : 124,
    "complexity" : 20063,
    "name" : "Current",
    "moduleCount" : 124
  },
  {
    "modules" : 124,
    "complexity" : 21063,
    "name" : "main",
    "moduleCount" : 124
  }
]

Count Module Dependencies

OVERVIEW: Outputs a sorted list of modules dependencies count of your project

USAGE: jungle modules --target <target> [<directory-path>]

ARGUMENTS:
  <directory-path>        Path to the directory where Podfile.lock or Package.swift is located (default: .)

OPTIONS:
  --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 modules --target jungle

Get dependant modules

OVERVIEW: Outputs a sorted list of targets that depends on the specified one in target

USAGE: jungle dependant --target <target> [--show-only-tests] [<directory-path>]

ARGUMENTS:
  <directory-path>        Path to the directory where Podfile.lock or Package.swift is located (default: .)

OPTIONS:
  --target <target>       The target in your Podfile or Package.swift file to be used (this can be a Product name in SPM)
  --show-only-tests       Show only Test targets
  --version               Show the version.
  -h, --help              Show help information.

Example:

jungle dependant --target SamplePackage $HOME/Desktop/SamplePackage

Library, LibraryTests, SamplePackageTests


### Visualize Complexity Graphs

```shell
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'.
  --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)
  --use-multiedge         Use multi-edge or unique-edge configuration
  --show-externals        Show Externals modules dependencies
  --version               Show the version.
  -h, --help              Show help information.

Outputs DOT format which can be viewed using http://viz-js.com

Some tips

๐Ÿ’ก Copy CSV (to paste in a spreadsheet) or DOT (to paste at http://viz-js.com) to the clipboard using pbcopy

jungle graph --target App ProjectDirectory/ | pbcopy
jungle history --target App ProjectDirectory/ | pbcopy

๐Ÿ’ก Use Graphviz tool to generate your own graphs

brew install graphviz
jungle graph --target App ProjectDirectory/ | dot -Tpng -o graph.png && open graph.png
