flagup

The beginnings of an exploration of a (possibly!) low-impact way of incrementally upgrading a large codebase from codegangsta/cli v1 flags to urfave/cli/v2.

Not sure if this approach may be more harmful than helpful, nor what kinds of blind alleys it may lead into.

Contents

• appv1/main.go - The "original" program using v1-style flags.
• utils/flags.go - The v1-style flag definitions.
• utils/const.go - Some constants that the flags reference.
• appv2/main.go - A revised version of the original program using v2-style flags, synthesized from v1-style flags.
• utils/flagup.go - The v2-style flag synthesizer.
