5905 :: I made a simple tutorial on how to create a CLI with Nim

  Hello folks,

  I'm still a beginner, but I wanted to create a simple CLI utility with Nim. The program saves a README.md template to the current directory.

  I wrote a tutorial about that. Perhaps it can help someone else, too.

  You might be interested in https://github.com/c-blake/cligen which can greatly reduce CLI boilerplate code at the cost of slightly less flexibility Re help messages.

  slightly less flexibility Re help messages.

  Now you're just being modest. cligen is awesome!! I can't think of starting a new CLI project without cligen now. What "slight less flexibility"? It has much more flexibility than I can think of (this is a compliment) :)

  I guess you can always just write your own whole usage="""blah blah""" string to say whatever you want bypassing the generated table. By going that way you do lose some substantial benefits in the first place, though. Total generality and total generation cannot happen simultaneously. "Slightly less flexibility" didn't seem such a crazy way to try to summarize that property to someone unfamiliar with the system (unlike @kaushalmodi), but maybe it was modest to the point of muddiness.
