Documentation

open_strings_env :: Sig.Parser [DeriveT.Pitch] Source #

TODO if Sig.Parser supported Deriver eval, I could make these return String, and not need to call indexed_strings.

string_env :: Sig.Parser (Maybe DeriveT.Pitch) Source #

with_string :: String -> Deriver a -> Deriver a Source #

insert_string :: String -> DeriveT.Environ -> DeriveT.Environ Source #

data String Source #

Constructors

String
Fields str_pitch :: !DeriveT.Pitch str_nn :: !Pitch.NoteNumber str_val :: !DeriveT.Val Assign this value to EnvKey.string for this string.

Arguments

:: Bool
-> Harmonic
-> [String]
-> Maybe String
-> Pitch.NoteNumber
-> Either Text (String, Harmonic)	Either Error (selected string, harmonic)

If string is given, try to find this pitch in the harmonics of that string. Otherwise, find the string from open_strings which has this as its lowest harmonic.
