Esmuflily is an extension for LilyPond that supports SMuFL compliant fonts, in particular, to facilitate the use of glyphs from Ekmelos : clefs, time signatures, noteheads, articulations, etc.
Esmuflily provides switches to turn the SMuFL support on or off for individual types of graphical objects (clefs, noteheads, etc.) and it defines additional commands and styles for SMuFL glyphs which are not available in LilyPond (notehead styles, function theory symbols, etc.) So scores can benefit from both SMuFL's comprehensive character set and LilyPond's awesome Emmentaler font.
Esmuflily requires LilyPond version 2.24.0 or higher.
