> Print directory or structured data in a tree like format.
**TTY::Tree** provides independent directory or hash data rendering component for [TTY](https://github.com/piotrmurach/tty) toolkit.
## Installation
Add this line to your application's Gemfile:
```ruby
gem "tty-tree"
```
And then execute:
$ bundle
Or install it yourself as:
$ gem install tty-tree

## 1. Usage
`TTY::Tree` accepts as input a directory path:
```ruby
tree = TTY::Tree.new(Dir.pwd)
tree = TTY::Tree.new("dir-name")
```
It can also be given as its input a `hash` data structure with keys representing directories and values as `array`s representing directory contents:
```ruby
data = {
dir1: [
"config.dat",
{dir2: [
{dir3: ["file3-1.txt"]},
"file2-1.txt"
]},
"file1-1.txt",
"file1-2.txt"
]
}
tree = TTY::Tree.new(data)
```
You can also construct tree with a DSL:
```ruby
tree = TTY::Tree.new do
node "dir1" do
node "config.dat"
node "dir2" do
node "dir3" do
leaf "file3-1.txt"
end
leaf "file2-1.txt"
end
node "file1-1.txt"
leaf "file1-2.txt"
end
end
```
The `TTY::Tree` can print the content in various formats. By default, a directory format is used by invoking `render`:
```ruby
puts tree.render
# =>
# dir1
# ├── config.dat
# ├── dir2
# │ ├── dir3
# │ │ └── file3-1.txt
# │ └── file2-1.txt
# ├── file1-1.txt
# └── file1-2.txt
```
The `render` call returns a string and leaves it up to the consumer how to handle the tree-like output.
## 2. Interface
### 2.1 new
In order to create `TTY::Tree` you need to provide either a path to directory which can be a `String`, `Pathname` or `Dir`:
```ruby
tree = TTY::Tree.new(Dir.pwd)
tree = TTY::Tree.new("dir-name")
tree = TTY::Tree.new(Pathname.pwd)
```
Or hash data structure:
```ruby
data = {
dir1: [
"config.dat",
...
]
}
tree = TTY::Tree.new(data)
```
As a shortcut notation, you can create a tree using `[]` like so:
```ruby
tree = TTY::Tree[Dir.pwd]
```
You can also use DSL to build a tree by using `node` and `leaf` methods:
```ruby
tree = TTY::Tree.new do
node "dir1" do
node "config.dat"
node "dir2" do
node "dir3" do
leaf "file3-1.txt"
end
leaf "file2-1.txt"
end
node "file1-1.txt"
leaf "file1-2.txt"
end
end
```
#### 2.1.1 `:level`
The maximum level of depth for this tree when parsing directory. The initial directory is treated as index `0`.
```ruby
tree = TTY::Tree.new("dir-name", level: 2)
# => parse directories as deep as 2 levels
```
#### 2.1.2 `:file_limit`
Prevent `TTY::Tree` descending directories with more than a given number of entries:
```ruby
tree = TTY::Tree.new("dir-name", file_limit: 2)
```
#### 2.1.3 `:show_hidden`
In order to for `TTY::Tree` to include hidden files in its output use `:show_hidden` option like so:
```ruby
tree = TTY::Tree.new("dir-name", show_hidden: true)
```
#### 2.1.4 `:only_dirs`
To only display directory entries in the output use `:only_dirs` option:
```ruby
tree = TTY::Tree.new("dir-name", only_dirs: true)
```
By default, hidden directories are not included in the output. If you wish to show hidden directories as well do:
```ruby
tree = TTY::Tree.new("dir-name", only_dirs: true, show_hidden: true)
```
### 2.2 render
By default, content is printed using `TTY::PathRenderer`. If you prefer a numeric notation of nested content, you can use `TTY::NumberRenderer` to enumerates each nested node like so:
```ruby
puts tree.render(as: :number)
# =>
# dir1
# 1.1 config.dat
# 1.2 dir2
# 2.3 dir3
# 3.4 file3-1.txt
# 2.5 file2-1.txt
# 1.6 file1-1.txt
# 1.7 file1-2.txt
```
#### 2.2.1 `:indent`
The number of spaces to use when indenting nested directories. By default, `4` spaces are used.
```ruby
tree.render(as: :dir, indent: 2)
```
## Development
After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake spec` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment.
To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and tags, and push the `.gem` file to [rubygems.org](https://rubygems.org).
