maddyboo·Aug 4, 2019Recommendation phrase
TopShell looks very interesting, thank you for sharing! This is a problem domain which I've been thinking a lot about recently. I write tons of shell (bash) scripts. I hate bash and its peculiarities, but it remains one of the quickest ways for me to get work done; I've tried to use many other languages to fill the gap of writing scripts that start as quick one-offs but have the potential to evolve into a more refined piece of software over time, but so far haven't had much luck. Most languages force me to go to great lengths for everything I want to do in this domain: - implementing command-line arguments/flags/subcommands: either overly-simplistic (getopts) or overly complex (cobra) - force me set up error handling for everything that could possibly go wrong - aren't flexible enough to transform 'soupy' data between various representati

ons without basically writing a full-blown custom parser - can sometimes be difficult to distribute a minimal-dependency release to remote machines or other users Functional languages are awesome for many of these things, but can be awkward when dealing with the side-effects that we normally want when dealing with scripting tasks. So far, what I gather from your readme/wiki is that TopShell is: a) A functional language seemingly inspired by ML, Haskell, et al. b) A reactive development environment for the language, à la Jupyter I love the code examples in the readme; I think this is something most people want to see but a lot of projects overlook. However, I think the readme is a bit barren on the philosophical front. You have a great wiki page [0] for that - I think it could be condensed and integrated into your readme so new visitors have a good idea of your vision. As someone who would consider using TopShell, my concerns are: - I can't find documentation on how I can use my own editor/environment if I want, rather than the web interface (which is nice for its notebook-like experience, but I don't see it fitting into my normal workflow) - I want to continue to integrate with programs which adhere to the unix philosophy; how does TopShell fit into this? - How dedicated are you to the development/maintenance of the project? - Do you forsee growing a community of contributors (and if so, how?), or do you want to keep this as a personal pet project? - Do you think the project will be alive in 1, 3, 5 years?
