ReverseStackTraces.jl

ReverseStackTraces.jl is an experimental Julia package that provides a way to display stack traces in reverse order, with the stacktrace ordered bottom to top. This can be useful in certain debugging scenarios where you have long stacktraces and you want to minimize scrolling.

Installation

To install the package, open a Julia REPL and run:

] add ReverseStackTraces.jl

Usage

Once installed, you can enable reverse stack traces by running the following command:

using ReverseStackTraces

After this command is run, stack traces will be displayed in reverse order by default.

Example

Here is an example of the default stack trace when running test/runtests.jl:

ERROR: LoadError: MethodError: no method matching +(::Int64, ::String)
Closest candidates are:
  +(::Any, ::Any, ::Any, ::Any...) at operators.jl:591
  +(::T, ::T) where T<:Union{Int128, Int16, Int32, Int64, Int8, UInt128, UInt16, UInt32, UInt64, UInt8} at int.jl:87
  +(::Union{Int16, Int32, Int64, Int8}, ::BigInt) at gmp.jl:537
  ...
Stacktrace:

   @ Main.ModuleC ~/gitrepos/ReverseStackTraces.jl/test/runtests.jl:5
 [2] func_b(#unused#::String, #unused#::Rational{Int64})

 [3] func_a(#unused#::Int64)

And here is the same stack trace using the ReverseStackTraces.jl package:

ERROR: LoadError:
