Print directory or structured data in a tree like format.
TTY::Tree provides independent directory or hash data rendering component for TTY toolkit.
Installation
Add this line to your application's Gemfile:
gem "tty-tree"
And then execute:
$ bundle
Or install it yourself as:
$ gem install tty-tree
Contents
1. Usage
TTY::Tree
accepts as input a directory path:
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:
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:
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
:
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
:
tree = TTY::Tree.new(Dir.pwd)
tree = TTY::Tree.new("dir-name")
tree = TTY::Tree.new(Pathname.pwd)
Or hash data structure:
data = {
dir1: [
"config.dat",
...
]
}
tree = TTY::Tree.new(data)
As a shortcut notation, you can create a tree using []
like so:
tree = TTY::Tree[Dir.pwd]
You can also use DSL to build a tree by using node
and leaf
methods:
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
.
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:
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:
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:
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:
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:
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.
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.
