I’ve created a custom logger, which doesn’t show `@debug` messages with Revise in Juno.  
If I `include()` the source file, it works in the REPL and Juno too. If I `includet` with Revise, then works in REPL, but not in Juno.  
`logtest.jl`:

```julia
module LogT

using Logging
using Logging: default_logcolor

export nosource_debuglogger,
        nosource_infologger,
        sourced_debuglogger,
        sourced_infologger

function nosource_metafmt(level, _module, group, id, file, line)
    color = default_logcolor(level)
    prefix = (level == Logging.Warn ? "Warning" : string(level))*':'
    suffix = ""
    return color, prefix, suffix
end

nosource_debuglogger() = ConsoleLogger(stderr, Logging.Debug, meta_formatter=nosource_metafmt)
nosource_infologger() = ConsoleLogger(stderr, Logging.Info, meta_formatter=nosource_metafmt)
sourced_debuglogger() = ConsoleLogger(stderr, Logging.Debug)
sourced_infologger() = ConsoleLogger(stderr, Logging.Info)

end

```

“Normal” include in the REPL:

```julia
julia> include("logtest.jl"); using .LogT

julia> using Logging

julia> @info "info"
[ Info: info

julia> @debug "debug"

julia> global_logger(nosource_debuglogger())
ConsoleLogger(Base.TTY(Base.Libc.WindowsRawSocket(0x0000000000000298) open, 0 bytes waiting), Info, Logging.default_metafmt, true, 0, Dict{Any,Int64}())

julia> @info "info"
[ Info: info

julia> @debug "debug"
[ Debug: debug

```

“Normal” include in Juno:

```julia
julia> include("logtest.jl"); using .LogT

julia> using Logging

julia> @info "info"
[ Info: info

julia> @debug "debug"

julia> global_logger(nosource_debuglogger())
ConsoleLogger(Base.TTY(Base.Libc.WindowsRawSocket(0x00000000000002a4) open, 0 bytes waiting), Info, Logging.default_metafmt, true, 0, Dict{Any,Int64}())

julia> @info "info"
[ Info: info

julia> @debug "debug"
[ Debug: debug

```

Revise include in the REPL (in a new session):

```julia
julia> using Revise; includet("logtest.jl"); using .LogT

julia> using Logging

julia> @info "info"
[ Info: info

julia> @debug "debug"

julia> global_logger(nosource_debuglogger())
ConsoleLogger(Base.TTY(Base.Libc.WindowsRawSocket(0x00000000000002ac) open, 0 bytes waiting), Info, Logging.default_metafmt, true, 0, Dict{Any,Int64}())

julia> @info "info"
[ Info: info

julia> @debug "debug"
[ Debug: debug

```

Revise include in Juno (in a new session):

```julia
julia> using Revise; includet("logtest.jl"); using .LogT

julia> using Logging

julia> @info "info"
[ Info: info

julia> @debug "debug"

julia> global_logger(nosource_debuglogger())
ConsoleLogger(Base.TTY(Base.Libc.WindowsRawSocket(0x0000000000000298) open, 0 bytes waiting), Info, Logging.default_metafmt, true, 0, Dict{Any,Int64}())

julia> @info "info"
[ Info: info

julia> @debug "debug"

julia> 

```

As shown above, with Revise in Juno the `@debug` messages are not shown.

Does anyone have an idea what happens here?

@pfitzseb or @tim.holy do you have an idea why this happens? (Sorry if it’s rude to directly mention people.)

Not really – I played around with this a bit and it looks like a Juno bug, but I’m not sure why it happens. Probably some weird interaction with both packages doing weird stuff to hook into the REPL.

Thank you! Then I’ll find a workaround for this concrete application. I’ll open an issue just for the record.
