Vi-Increment

Increment and decrement numbers easily with Ctrl+a and Ctrl+x:

Usage

Vi-increment registers itself as a Vi change, so numeric prefixes and the dot command can be used:

$ 200             # 10<C-x>
$ 190             # 200.
$ -10             # .
$ -210

With setopt octalzeroes, Vi-increment will let Zsh-native arithmetic detect octal numbers and preserve them:

$ 0077            # <C-a>
$ 0100

Binary numbers are also detected and preserved:

$ 0b100011        # 11<C-x>
$ 0b11000

Vi-increment will also preserve leading zeroes, and fully supports negative numbers:

$ (( -0x0040 ))   # 8<C-a>
$ (( -0x0038 ))

Features

• Operates in both visual and vicmd modes
• Preserves leading zeroes
• Preserves C-formatted hexadecimal numbers: 0x[hex]
• Preserves C-formatted binary numbers: 0b[binary]
• If setopt OCTAL_ZEROES: Preserves C-formatted octal numbers: 0[oct]

Future features:

• Detect and preserve arbitrary zsh-format base [base]#[num]
• Preserve underscores
