EponymKeywordSyntax.jl

@eponym(ex)

The @eponym macro infers the name of a keyword argument from the name of its value. This is best explained by example:

julia> using EponymKeywordSyntax

julia> f(args...; kw...) = (args=args, kw=kw)
f (generic function with 1 method)

julia> oh_dear_this_is_long_I_dont_want_to_write_it_twice=3
3
julia> f(oh_dear_this_is_long_I_dont_want_to_write_it_twice=oh_dear_this_is_long_I_dont_want_to_write_it_twice) == @eponym f(;oh_dear_this_is_long_I_dont_want_to_write_it_twice)
true

julia> a=1; b=2;
2

julia> f(a=a, b=b) == @eponym f(;a,b)
true

julia> (a=a, b=b) == @eponym (;a, b)
true

julia> (a=a, b=10) == @eponym (;a, b=10)
true

julia> f(1, a=a, b=b) == @eponym f(1;a, b)
true
