Debugging

To view logs without stdout interfering with the usage of the library, logs can be piped to a socket in a different terminal.

Listen in to the logging socket with nc -l -p 1234. It may be helpful to do this in a while loop so that the REPL may be repeatedly shut down and restarted (breaking the pipe).

This snippet uses fish shell, but this can be adapted to bash, zsh, etc.

while true
   echo "listening for logs"
   nc -l -p 1234
nd

Then, enable the pipe logging from VimBindings with VimBindings.enable_logging():

# ~/.julia/dev/VimBindings
julia --project -i -e "using VimBindings; VimBindings.enable_logging()"

Logging can also be enabled after initialization:

julia> VimBindings.enable_logging()
Logging.ConsoleLogger(IOBuffer(data=UInt8[...], readable=false, writable=false, seekable=false, append=false, size=0, maxsize=0, ptr=1, mark=-1), Info, Logging.default_metafmt, true, 0, Dict{Any, Int64}())

Once logging is enabled, you should see something like this from nc:

┌ Debug: initializing...
└ @ VimBindings ~/.julia/dev/VimBindings/src/VimBindings.jl:156
┌ Debug: Task (runnable) @0x00007f13d92b7080

Disabling precompile

set_preferences!(VimBindings, "precompile_workload" => false; force=true)
