Concatenative Programming
Hello!
This space is for sharing news, experiences, announcements, questions, showcases, etc. regarding concatenative programming concepts and tools.
We'll also take any programming described as:
- pipelined
- stack-oriented
- tacit
- postfix / reverse Polish notation (RPN)
From Wikipedia:
A concatenative programming language is a point-free computer programming language in which all expressions denote functions, and the juxtaposition of expressions denotes function composition. Concatenative programming replaces function application, which is common in other programming styles, with function composition as the default way to build subroutines.
For example, a sequence of operations in an applicative language like the following:
y = foo(x)
z = bar(y)
w = baz(z)
...is written in a concatenative language as a sequence of functions:
x foo bar baz

So it looks like a totally different data flow style, and (I think) geared toward writing then running programs, whereas Stacker is more for interactive stack-oriented calculator tasks.
lisps are very repl-driven too
I'd say an important part of this calculator's interaction model is doing something, getting a result, then doing something else to that result. That's not too bad in the regular Python interpreter either.
For example, in Python:
In Stacker:
Does Hy have something like the Python interpreter's
