In general I think ignoring error should be avoided where possible. I think we can likely encapsule this in a function that can be called wherever we need it:

func getMaxWidth() int {
    out, err := strconv.Atoi(c.Options["maxwidth"])
    if err != nil {
        out = 100
    }
    if out < 10 {
        out = 10
    }
    return out
}

It makes sense that we could really just store the value in a module var:

var MaxWidth = getMaxWidth()

Then in the code for setting config values have a case for changing maxwidth and reset the var. Then we can just reference the var everywhere instead of recasting to int in a few places (that said, I have not gotten to do a deep dive into your changes, just a cursory look.... so I may be overthinking this).

070f7eb6ba261866395706f709d12dff3ead2e74 contains a first pass on this. Since c.Options is both a field on the struct and altered by reading in the configuration after instantiating the struct, it's a bit less clean.

Other potential options:

  • add a piece of state to hold a sync.Once (existed in 1.12) in getMaxWidth to avoid the checks and casts
  • have some hook on the client that gets called after the configuration file is read in
  • see if the configuration can be read in first, then passed to the client constructor, then maxWidth can be a field on the client alongside Width

I'm not sure I follow why this is here. Since we are trying to wrap at maxwidth and remove hardcoded values in favor of the passed value that comes from the config, why are we hardcoding 100 here?

The intent here was to catch malformed / missing configuration entries: your suggestion of wrapping the logic into a getMaxWidth function will solve this problem and remove the need here.

Much better, thanks!
