This plugin is a resurrection of the first plugin/recipe I ever wrote for Kakoune.
I deleted the original repository and created a new one:
The new version has been improved by the inclusion of a default character and a default count, which can be updated along the current editing session.
This makes the insertion of repeated characters (for example, ASCII horizontal rulers) very fast and hassle-free.
EDIT
The plugin has been further improved by giving it the capacity to “underline” the string on the preceding line, as in this screenshot.
