pod-tree

Display a tree visualization of a CocoaPods Podfile.lock dependency graph, similar to the cargo tree command.

pod-tree parses your Podfile.lock and prints a text-based tree of your pods and their dependencies.

Features

Currently, it supports limiting the depth and viewing (reverse) dependencies of a specific pod. Which is mostly I used with cargo tree.

Installation

Install from crates.io:

cargo install pod-tree

Build from source:

git clone https://github.com/Binlogo/pod-tree.git
cd pod-tree
cargo install --path .

Usage

Run pod-tree in the directory containing your Podfile.lock:

pod-tree

By default this reads Podfile.lock in the current directory and prints the full dependency tree.

Options

• --lockfile <LOCKFILE> – Path to the Podfile.lock file (default: Podfile.lock).
• --depth <DEPTH> – Maximum display depth of the dependency tree (1 = direct dependencies).
• -i, --invert – Show reverse dependencies for the given package.
• PACKAGE (positional) – Package to focus on (shows only its tree; with --invert shows reverse dependencies).

These options are implemented in the CLI parser in src/main.rs:11-30.

Examples

Show the full dependency tree from Podfile.lock:

pod-tree

Limit the depth to direct dependencies only:

pod-tree --lockfile examples/OnionBrowser/Podfile.lock IPtProxyUI --depth 2
Podfile.lock

Show reverse dependencies of a specific pod:

pod-tree --lockfile ./examples/wikipedia-ios/Podfile.lock AFNetworking/NSURLSession -i
