Module:MOS scalesig

Module documentation[view] [edit] [history] [purge]

This module should not be invoked directly; use its corresponding template instead: Template:MOS scalesig.

Module:MOS scalesig formats a string into a mos scale signature, with non-breaking spaces and, if non-octave, the appropriate brackets. Scale signatures can optionally be formatted as a link to the scale's wiki page.
