New issue 4487 by [email protected]: Implement partial function calls.
https://code.google.com/p/lilypond/issues/detail?id=4487
Implement partial function calls.
Contains two commits, see particularly the regtest as an example.
I'm not convinced this idea is as good as I thought when coming up
with it: it may be that this particular use case is not frequent
enough to warrant the complexity.
It seems nice for defining aliases like
tagv = \tag '(violinI violinII) \incomplete
or
important = \tweak color #red \tweak font-size 3 \incomplete
but I'm not sure that this warrants the effort.
Discuss.
Allow for chaining of several partial functions in a row
Chaining only works when all function calls except the last one have all
arguments supplied already, with their last argument being the rest of
the chained call.
Implement partial function calls
A partial function call acts as a function where the start of the
argument list has already been supplied. For example:
makeRed = \tweak color #red \incomplete
Then one can use this as
{ c' \makeRed d' e'-\makeRed -. }
