# LuaDiffer: A simple lua diff library

This is a simple lua module that performs a diff on two strings and returns a table of
string chunks.

## Example

```lua
make_diff = require "diff"
s1 = [[hello
...
to the
world]]
s2 = [[hello
...
*at* the
world]]
diff = make_diff(s1, s2)
```

returns the table:

```
{
  {old="hello\n...\n", old_line=1, old_line_end=2,
   new="hello\n...\n", new_line=1, new_line_end=2},
  {old="to the\n", old_line=3, old_line_end=3,
   new="*at* the\n", new_line=3, new_line_end=3},
  {old="world", old_line=4, old_line_end=4,
   new="world", new_line=4, new_line_end=4},
}
```

and running:

```lua
diff:print{color=false}
```

produces the output:

```
  hello
  ...
- to the
+ *at* the
  world
```
