A simple RPN calculator with ed
-style input. A dc
clone with almost none of dc
's functionality.
Why:
- ed and rpn are both unusable, so combining the two is funny
- I was sick of opening Python for simple math
- to practice Rust
- arbitrary precision (using
rug
?) - rational numbers
- handle pipes, input file
- control-l, arrows (capture input without <Enter>? pros and cons...)
- vi-mode for maximum unusability
