Asciinurse

Asciinurse is a set of useful extensions to make Asciidoctor even better!

Installation

Add this line to your application’s Gemfile:

gem 'asciinurse'

And then execute:

$ bundle

Or install it yourself as:

$ gem install asciinurse

Configuration

Asciinurse uses, by default, a $HOME/.asciinurse directory. To change this, just declare a ASCIINURSE_USER_DIR variable containing the directory of your choice.

Anything can be overridden in Asciinurse just by placing the same file in your ASCIINURSE_USER_DIR (maintaining the tree, of course). This means that if you don’t like our provided resource (such as the chart templates), you can just drop your version of it and Asciinurse will use that. You can also override any config key by using the $ASIINURSE_USER_DIR/asciinurse.yml file.

Charts

This extension enables the use of charts in documents. With an html5 backend, Asciinurse will generate a chart using HTML and Javascript (using the canvas tag). The supported engines are:

Important

Highcharts is the default engine because Google Charts does not allow offline use. Make sure you have the rights to use it or switch to Google Charts.

Usage

It’s pretty straightforward to use charts. Just declare the engine you want to use (or leave it to use the default):

:charts: highcharts

To insert a chart, you have three ways:

  • Point to a json to configure the chart (maximum flexibility)

  • Point to a csv file that contains the data

  • Insert the data as a csv file inline

Using a JSON file

If you use Highcharts, you can put the json file as if in a web page. For Google Charts, you need to pass a JSON containing the following attributes:

type

The object that will draw the chart (like google.visualization.PieChart)

data

The datatable that holds the data (you can wrap a multidimensional array using the function google.visualization.arrayToDataTable as well)

options

The chart options to pass (as if using in a web page)

style

The chart dimensions (width and height)

chart::mychart.json[]

Using a CSV file

You can drop a CSV file and make a reference to it:

chart::mychart-data.csv[type=pie]
Important

Remember to use a CSV with a header and pass the chart type.

Inline a CSV

.Inline Chart
[chart,pie]
....
CSV DATA HERE
....
Important

Remember to use a CSV with a header and pass the chart type.

Chart Images

To put charts on a PDF file, we need to produce a temporary image from the HTML5 chart. Asciinurse’s default implementation uses PhantomJS and requires an accessible phantomjs executable in your PATH.

Important

Remember that you will need an Internet connection for generating images from Google Chart.
