Pretty-print tree-like structures
The ptree crate supports output formatting due to a user-provided configuration file and/or environment variables.
Usage
[dependencies]
ptree = "0.2"
Constructing a tree
There are two main ways of using ptree to print a tree-like data structure.
The first is to implement TreeItem for your structure.
The second is to create a new tree, either using TreeBuilder or by manually constructing StringItems.
The ptree crate includes implementations of TreeItem for some common types, including a custom StringItem and petgraph::Graph.
Printing the tree
A tree can be printed to standard output using print_tree, or to an arbitrary writer using write_tree.
Both functions have variants which take a PrintConfig that controls the output.
Text is formatted using ansi-term, which allows changing colors and styles of the printed text.
User configuration
By default, ptree loads configuration from a user configuration file.
This allows end users to globally configure the output format for all applications using ptree.
Applications can use this configuration directly, modify it, or ignore it altogether.
