ThreadLocalCounters.jl provides a macro @tlc to associate a counter to a code location.
julia> using ThreadLocalCounters
julia> hello_world() = @tlc hello_world;The installed counters can be enumerated using ThreadLocalCounters.list:
julia> ThreadLocalCounters.list(; all = true)
1-element Vector{ThreadLocalCounters.Internal.ThreadLocalCounter}:
[0] hello_world @Main #= REPL[2]:2 =#The thread-local counter is incremented each time the program hits the associated code location:
julia> hello_world();
julia> ThreadLocalCounters.list()
1-element Vector{ThreadLocalCounters.Internal.ThreadLocalCounter}:
[1] hello_world @Main #= REPL[2]:2 =#
julia> hello_world();
julia> ThreadLocalCounters.list()
1-element Vector{ThreadLocalCounters.Internal.ThreadLocalCounter}:
[2] hello_world @Main #= REPL[2]:2 =#
