Cork is a simple command-line calculator, mainly targeted towards people who deal with hex numbers. It deals only with integer arithmetic. Expressions may involve mixed bases (limited to decimal, hexadecimal, octal and binary numbers). The global output format may be set to a particular radix - by default it is hex.
Cork is something that I wrote over a weekend, when I was getting annoyed at having to punch in 16 digit hex numbers on my calculator. I wanted something on my screen, and naturally on the terminal. But all the calculator programs that I found online (including a REPL of Python and Octave) had a glaring problem - they could work on hex numbers, but the output was always in decimal. So I hit to
cargo new ...
Cork is a rather odd name for a calculator. I wanted something on the lines of kernel calculator, but that's way too long. So kernel became core (technically, that's what it means in English) and calculator, well that can be C. So we have CoreC ... maybe CorC ... ah right, Cork.
For Linux, you can download a pre-built binary here.
Build from source
If you have
cargo installed, then you can build this from source:
git clone https://github.com/RedDocMD/cork cd cork cargo build --release
The binary produced will be
To install from crates.io, run
cargo install cork. Then, Cork should be executable with the
Cork is a REPL calculator, so you can put in expressions and it displays the answer. A sample run goes like:
Welcome to cork - a calculator for hex-lovers! Press Ctrl + D to exit. cork> 0xCAFE 0xcafe cork> 0xCAFE + 2 * 8 * 0x20 0xccfe cork> set of dec cork> ans 52478 cork> 0xCAFE 51966 Exiting ...
Oh, btw, Cork uses rustyline. So you get the whole
readline goodness (including a history).
Cork accepts four types of numbers:
- Decimal: These are regular numbers (10, 23245, 4124, etc).
- Hexadecimal: These are numbers prefixed by
0x(0xaA 0x5acd, 0x101c, etc).
- Octal: These are numbers prefixed by
0o(0o12, 0o55315, 0o10034, etc).
- Binary: These are numbers prefixed by
0b(0b1010, 0b101101011001101, 0b1000000011100, etc).
ans holds the answer of the last computation. It is initialized to
0 on startup.
Cork has something called set directives, which basically set some global property. They are of the form
set <key> <value>
As of now, Cork has the following keys:
|of||hex, dec, oct, bin||Sets the output format|
