EponymKeywordSyntax

Important: This package is obsolete

On Julia 1.5 and above eponym keyword syntax is supported by the julia language directly. Older Julia versions can get it from Compat.jl. So EponymKeywordSyntax is not needed anymore.

Usage

This package provides the @eponym macro, which 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
