Wrap-selection micro plugin for IntelliJ

gistfile1.groovy

import static liveplugin.PluginUtil.*

// This is micro-plugin for IntelliJ to wrap long lines with separator.
// E.g. list literal like this [1, 2, 3, 4, ..., 200000] can be split into somewhat more readable
// [1, 2, 3, 4,
//  5, 6, 7, 8
//  ..., 200000]
// (Note that this code can only be executed within this plugin https://github.com/dkandalov/live-plugin)
