Number Converter

A simple base conversion project in Rust.

Installation

Clone the repo and run cargo build --release. The executable numconverter will be in the target/release directory. Run from there, or move/symlink to a location in your PATH (~/bin/ for example).

I alias the name to ncon and derivatives, based on what base I'm inputing:

alias ncon="numconverter"
alias bcon="numconverter --from-base 2"
alias ocon="numconverter --from-base 8"
alias hcon="numconverter --from-base 16"

Dependencies

Built using Rust. (Rust installation instructions).

• Uses the structopt crate to handle command line input.
• Uses the clipboard crate to handle read and write to clipboard. [For Linux: x11_clipboard & nix crates]

Linux

Dependencies for clipboard functionality include:

• libxcb-shape0-dev
• libxcb-xfixes0-dev

Install with

sudo apt-get install libxcb-shape0-dev libxcb-xfixes0-dev

$ numconverter 255

Enter numconverter --help for available options.

numconverter [base_char] [from_num] [to_base]... [FLAGS]... [OPTIONS]...

ARGS:
    base_char   (b, o, d, h - binary, octal, decimal, hex) Character
                representing the 'from' base.  If both the base_char and
                the -f/--from-base are provided, base_char will be used.
    from_num    The input number to convert.  Default base 10.
    to_base     A list of base 10 numbers to convert from_num to.  Base
                must be between 2 and 32 inclusive.

FLAGS:
    -b, --bare              Disable Pretty Print
    -c, --copy              Copy the resulting ouput to clipboard
        --from-clipboard    Get the input number from clipboard
    -h, --help              Prints help information
        --no-sep            Do not pad the output
    -s, --silent            Do not print output, for use with the clipboard on.
    -V, --version           Prints version information
    -v, --verbosity         Verbosity (more v's, more verbose)


OPTIONS:
    -f, --from-base <from-base>      Base of the input number [default: 10]
    -p, --pad <pad>                  Pad the output with leading 0s [default: 0]
        --sep-char <sep-char>        Specify spacer char [default: _]
    -l, --sep-length <sep-length>    Put a spacer every N characters [default: 4]

Contributing

Before submitting a PR, please make sure you have:

• Run cargo test.
  • This runs all the defined tests. Be sure to add test coverage for your PR when possible! 😁
• Checked there are no warnings when compiling.
  • cargo clean && cargo build ensures everything is compiled fresh and will give you maximum visibility on warnings.
  • TravisCI will be run with cargo build --features=fail-on-warnings, so give that a check to avoid waiting on the long CI build.
• Run cargo fmt and commit the result.
  • Some of the results when automatically formatting are not ideal (in my opinion), but a common format is better than inconsistent format (also in my opinion). The default format is a safe decision to be consistent with the rest of the Rust community. If there is a formatting decision you find untenable, open an Issue and start a discussion (please be civil, see the Code of Conduct 😉).
