Hi there!
Does anyone know why doctests are not displayed in the REPL help mode?
For instance this works
````julia
julia> """
foo(x)
Compute the foo.
# Example
```julia
foo(0) == 1 # true
```
"""
foo(x) = 1
foo
help?> foo
search: foo floor pointer_from_objref OverflowError RoundFromZero unsafe_copyto! functionloc
foo(x)
Compute the foo.
Example
≡≡≡≡≡≡≡≡≡
foo(0) == 1 # true
````
But this doesn’t.
````julia
julia> """
bar(x)
Compute the bar.
# Example
```jldoctest
bar(0)
# output
2
```
"""
bar(x) = 2
bar
help?> bar
search: bar baremodule SubArray GlobalRef clipboard BitArray backtrace BitMatrix
bar(x)
Compute the bar.
Example
≡≡≡≡≡≡≡≡≡
````
As you can see the example block shows up empty.
My best guess is that Documenter.jl is not “core Julia” and so a block tagged with `jldoctest` has no reason to show up, but it is still a bit annoying.

It should show up. It is even recommended (6. at [Documentation · The Julia Language](https://docs.julialang.org/en/v1/manual/documentation/#Writing-Documentation)).
What Julia version are you using? I tried running both your snippets in 1.8.5 and 1.9.0-rc3, and both examples show up for me in both versions.

Are you using `OhMyREPL`? I found the same exact issue and realized that it was `OhMyREPL` that was causing it.

let me try without OhMyREPL!

You’re right, that was it!
