Module:MOS scalesig

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

Note: Do not invoke this module directly; use the corresponding template instead: Template:MOS scalesig.

This module depends on the following other modules: Module: Arguments Module: MOS Module: Utils Module: Yesno

This module formats a string into a mos scale signature, with non-breaking spaces. Scale signatures can optionally be formatted as a link to the scale's wiki page.

To include this module in other modules, use local mos_scalesig = require("Module:MOS scalesig")._mos_scalesig.

-- Function to format a string into a mos scalesig, with nonbreaking spaces.
-- Options are:
-- - is_long - Whether to use "xL ys<p/q>" or "xL ys (p/q-equivalent)". Only
--   applies for nonoctave mosses, as a scalesig without an equave is assumed to
--   be 2/1-equivalent.
-- - is_link - Whether the scalesig is a link to its wiki page.
