Need to create boxes in boxes in boxes in boxes? Great news! You've found a gem that does just that. This is a dive into the world of command line apps using TTY focusing on the tty-box and supporting gems. This has been done in a way to extend out the customization of each box quite easily by adding additional root properties to the boxes. For the purpose of this exercise I've chosen to stick with just the examples given in the challenge as well as the ability to craft new box nesting patterns by supplying custom JSON configs.
Add this line to your application's Gemfile:
gem 'boxybox'And then execute:
$ bundle
Or install it yourself as:
$ gem install boxybox
To print one of the 4 provided examples along with the config json used to construct the boxes use the following command
$ boxybox boxes -e example1 -pThis is helpful when wanting to understand the config syntax with clear examples.
$ boxybox boxes -f ~/some_config.jsonUse the above command if you wish to pass in a custom JSON config.
The following example shows how boxes can be configured using JSON. There is a top level boxes object which represents our outer or parent box.
Each box may have children boxes in a horizontal or vertical pattern which is designated by the direction property. children are given as an array with content boxes using the content propery. The examples given follow the examples given in the project requirements, however content can be populated with text and all boxes will scale properly.
While this may be a bit overkill, using JSON in this way allows for more complicated structures in the future. As this gem utilizes the tty toolset, specifically the tty-box gem, many properties may be passed through and included in the future with relative ease.
{
"boxes": {
"direction": "vertical",
"children": [
{
"direction": "horizontal",
"children": [
{
"direction": "vertical",
"children": [
{
"content": " "
},
{
"content": " "
}
]
},
{
"content": " "
},
{
"content": " "
}
]
},
{
"content": " "
},
{
"content": " "
},
{
"direction": "horizontal",
"children": [
{
"content": " "
},
{
"content": " "
}
]
}
]
}
}The above config will print out the following:
