npm explore hypernal && npm run demo
hypernal(options:Object)
creates a render only terminal and returns an interface to interact with it as described below.
options:
- allow overriding
{ cols: Number, rows: Number }of the terminal, which generally is not necessary Note:- number of cols will be applied to any row
- number of rows will indicate how many rows to add initially, but more will be added if needed
term.tail:Boolean
- when set to true, the terminal will automatically scroll to the bottom when more lines are added than fit in its container
term.appendTo(elem:String|Object)
appends the terminal to the given DOM element.
term.write(s:String)
writes the given string to the terminal.
term.writeln(s:String)
writes the given string to the terminal and adds a line break.
term.reset()
clears the terminal
hypernal is basically a trimmed down version of tty.js focused on and improved for rendering only.
