This project is based on an idea from Gabriella Gonzalez.

align-equal is a command-line tool that aligns text based on the = symbol.
It ensures that all = signs are vertically aligned, improving readability.

This program reads text from standard input, processes it, and outputs the aligned result to standard output.

Installation

To install align-equal using cabal, run:

cabal install align-equal

Usage

Using in Vim

align-equal is primarily designed for use within Vim. You can align selected text in visual mode as follows:

1. Select the lines you want to align in visual mode (V for line-wise selection).
2. Run:

   :!align-equal
   

3. The selected text will be replaced with an aligned version.

Example

Before (Selected Text in Visual Mode):

x = 1
longVariable = 2
short = 3

Command:

:!align-equal

After:

x            = 1
longVariable = 2
short        = 3

How it Works

align-equal scans the input, detects = symbols, and aligns them by adding the appropriate amount of whitespace.
