ansi-interpolator Build Status

A scala (2.11+) macro based ansi interpolator.

It has two advantages over non-macro interpolators:

  • is faster and lighter (brings no extra dependency at runtime)
  • detects syntax issues at compile time

Usage

Add the following dependency to your SBT project:

"org.backuity" %% "ansi-interpolator" % "1.1" % "provided"

Note about provided: see this stackoverflow answer for a better SBT dependency scope.

Import the AnsiFormatter and use the ansi interpolator:

import org.backuity.ansi.AnsiFormatter.FormattedHelper

ansi"Text containing ansi tags such as %bold{bold text} or %underline{can be %yellow{nested}}"

Here is the list of supported tags:

  • bold
  • underline
  • italic (may not work on every terminal)
  • blink (may not work on every terminal)

And color tags:

  • black
  • red
  • green
  • yellow
  • blue
  • magenta
  • cyan
  • white

Syntax errors are detected at compile time

[error] .../Main.scala:17: Unsupported tag underlin
[error]     println(ansi"Please %underlin{underline this : $str}")
[error]                          ^
