I have the following which tries to apply a relative unit range to a string whose length is unknown:
function testnums(data::String,numrange::String)
data[numrange]
end
foo = "asdfasdfasdf"
bar = "end-3:end"
testnums(foo,bar)
Here is the error
``` MethodError: no method matching getindex(::String, ::String) Closest candidates are: getindex(::String, !Matched::UnitRange{Int64}) at strings/string.jl:245 getindex(::String, !Matched::Int64) at strings/string.jl:210 getindex(::String, !Matched::UnitRange{#s69} where #s69<:Integer) at strings/string.jl:242 ... testnums(::String, ::String) at passargs.jl:2 top-level scope at passargs.jl:7 ```As suggested by the error, you can’t pass a string for the range. So how can I pass a relative range eg end-3:end?
