Clc is a Command line calculator written in Rust 🦀 It eval given expression and print result.
There are prebuilt x86-64 binaries for Linux, macOS and Windows on the release page.
You can install the latest release from source using cargo, or build directly from a source checkout.
shell
cargo install clc
shell
curl -sSLf https://github.com/ymgyt/calculator/releases/download/0.1.4/clc-x86_64-unknown-linux-gnu.tar.gz | tar zxf - -C /usr/local/bin
shell
curl -sSLf https://github.com/ymgyt/calculator/releases/download/0.1.4/clc-x86_64-apple-darwin.tar.gz | tar zxf - -C /usr/local/bin
To use clc with docker, execute the following command.
shell
docker run --rm -it ghcr.io/ymgyt/clc:latest
Execute the clc
command to start a repl session. type the expression to evaluate and press Enter.
To exit the session, type quit
or press Ctrl + C.
text
$ clc
Version: v0.1.4
To quit, press Ctrl+C or type quit
⯠sqrt(sqrt(16)) * (100 - 1) * (100 + 1) / 9
2222
⯠quit
bye
You can also retrieve results directly without using a repl session. pass the expression to evaluate with --eval
flag
shell
clc --eval 'sqrt(-2^2) - abs(2)'
Some functions take lambda expression as argument.
A lambda expression is written like |x| { x^2 }
.
{
,}
are optional, so the above expression can also be written as follows |x| x^2
.
```shell
⯠sig(1,10 |x| x^2)
385
⯠sig(1,10 |x| sig(1,10 |y| x*y)) 3025 ```
