philiprehberger-diff-assert

Better test assertion diffs with colored inline comparisons.

Instead of the default assert_eq! output that dumps raw Debug representations, assert_eq_diff! shows a colored line-by-line diff so you can immediately see what changed.

Quick start

use philiprehberger_diff_assert::assert_eq_diff;

let expected = "hello\nworld";
let actual = "hello\nworld";
assert_eq_diff!(expected, actual);

Programmatic use

use philiprehberger_diff_assert::diff_strings;

let diff = diff_strings("a\nb\nc", "a\nx\nc");
// Returns a formatted diff string (with ANSI color codes)

NO_COLOR support

If the NO_COLOR environment variable is set, all color output is suppressed automatically. You can also use diff_strings_no_color explicitly.

Macros

assert_eq_diff

Asserts that two expressions are equal, showing a colored line-by-line diff on failure.

Functions

diff_debug

Returns a formatted diff of two values using their Debug representations.

diff_strings

Returns a formatted line-by-line diff of two strings with ANSI color codes.

diff_strings_no_color

Returns a formatted line-by-line diff of two strings without ANSI color codes.
