I’ve a package with global variables related to a file open
(*os.File), and its logger associated.
By another side, I’ll build several commands that are going to use
that package and I want not open the file to set it as logger every
time I run a command.

So, the first program to run will set the global variables, and here
is my question:

  • Do the next programs to use the package can access to those global
    variables without problem? It could be created a command with a flag
    to initialize those values before of be used by another programs, and
    another flag to finish it (unset the global variables in the package).

  • If that is not possible, which is the best option to avoid such IO-bound? To use a server in Unix sockets?

    Assuming by ‘program’ you actually mean ‘process’, the answer is no.

    If you want to share a (customized perhaps) logging functionality between processes then I would consider a daemon-like (Go doesn’t yet AFAIK support writing true daemons) process/server and any kind of IPC you see handy.
