This is the second post in a series detailing the issues, progress, and design decisions used in clap v3. This post details removing the "stringly typed" nature of clap. NOTE: This post uses String heavily, however, the acutal clap code doesn't usually deal in Strings per se. Usually &str to keep from allocating more than absolutely required. But for simplicity sake, I'll be using String the majority of the time in this post. Issue: Removing Strings One of the biggest complaints about clap is the “stringly typed” nature of arguments.

Since my last post, countless bug fixes, features, etc. have been merged into the project. There's also a wave of new contributors who I'm immensely grateful for! Something I've been struggling with for the past few months is conflicting priorities to get 3.x out the door, and include all the new feature requests.

I've decided it's time to get to work, I'm implementing a feature freeze for clap in an effort to get 3.x out the door, at which point the refactoring made in 3.x should also…

It's been quite a while since I wrote anything blog-ish about clap, or anything else for that matter. I've had quite a few ideas that I've wanted to talk about, sadly those will have to wait a while longer. For now, I'd like to announce the new site https://clap.rs and obviously this associated blog https://blog.clap.rs My goal is to write more about the neat things that are happening in clap and keep people in the loop on ideas or new features. I have also started a re-make of the old video tutorials; the new ones can be found on youtube. This series aims to go far more in depth into each feature and how to use them. Currently there are only a handful of topics covered, but as I get…
