URI Differ

Simple lib to find diffs between URI and represent it in pretty way.

##Quick start:

Use maven:

<dependency>
    <groupId>ru.lanwen.diff</groupId>
    <artifactId>uri-differ-lib</artifactId>
    <version>1.3.0</version>
</dependency>

Add some code:

Get changes:

UriDiff changes = UriDiffer.diff()
    .expected("http://ya.ru").actual("http://yandex.ru").changes();

Print them:

String report = changes.report();

Use any report generator with implementing ReportView:

String report = changes.report(DefaultUrlDiffView.withDefaultView());

What it returns:

Expected	Actual	Report
httpf://ya.ru	httpfs://ya.ru	httpf[+s]://ya.ru
httpfd://ya.ru	http://ya.ru	http[-fd]://ya.ru
httpfd://ya.ru	httpgt://ya.ru	http[fd->gt]://ya.ru
httpf://ya.ru	http://ya.ru	http[-f]://ya.ru
httpf://ya.ru	httpg://ya.ru	http[f->g]://ya.ru
htspf://ya.ru	httpg://ya.ru	ht[s->t]p[f->g]://ya.ru
htspf://ya.ru	httpg://ya.ru/h	ht[s->t]p[f->g]://ya.ru[+/h]
http://ya.ru	http://yandex.ru	http://[ya->yandex].ru
http://yandex.ru	http://yandex.com.tr	http://yandex.[ru->com.tr]
http://yandex.com	http://yandex.com.tr	http://yandex.com.[+tr]
http://yandex.com.tr	http://yandex.com	http://yandex.com.[-tr]
http://yandex.com.tr.fr	http://yandex.com	http://yandex.com.[-tr.fr]
/path?q=1	/changed?q=2	/[path->changed]?[q=1->q=2]

##Use filters:

UriDiffer.diff()
    .expected("http://ya.ru").actual("https://yandex.ru/?ncrnd=2342")
    .filter(scheme(), param("ncrnd")).changes();

Scheme filter:

To ignore any scheme, add filter SchemeFilter.scheme().
You can also specify which schemes are allowed: SchemeFilter.scheme("http", "https").

Parameter filter:

To ignore parameter with some name, just add AnyParamValueFilter.param("param_name").
You can also specify which values only can be ignored: AnyParamValueFilter.param("param_name").ignore("val1", "val2").
