html-diff
Calculate difference between two HTML snippets and return those differences as a merged HTML snippet showing the changes.
Usage:
var cfg = &htmldiff.Config{
Granularity: 5,
InsertedSpan: []htmldiff.Attribute{{Key: "style", Val: "background-color: palegreen;"}},
DeletedSpan: []htmldiff.Attribute{{Key: "style", Val: "background-color: lightpink;"}},
ReplacedSpan: []htmldiff.Attribute{{Key: "style", Val: "background-color: lightskyblue;"}},
CleanTags: []string{""},
}
res, err := cfg.HTMLdiff([]string{previousHTML, latestHTML})
mergedHTML := res[0]
Only deals with body HTML, so no headers, only what is within the body element.
Requires Go1.5+, with vendoring support. Vendors "github.com/mb0/diff", "golang.org/x/net/html" and "golang.org/x/net/html/atom".
Running the tests will create output files in testout/*.html.
For fuzz-testing using https://github.com/dvyukov/go-fuzz , the Fuzz() function is in fuzz.go (as at Feb'16 you need to rename the vendor directory while you fuzz, and go get the dependencies - an issue with "go/importer", see https://github.com/golang/go/issues/13756).
Pull requests welcome.

Types ¶
type Attribute ¶
type Attribute struct {
Namespace, Key, Val string
}
Attribute exists so that this package does not export html.Attribute, to allow vendoring of "golang.org/x/net/html".
type Config ¶
type Config struct {
Granularity int // how many letters to put together for a change, if possible
InsertedSpan, DeletedSpan, ReplacedSpan []Attribute // the attributes for the span tags wrapping changes
CleanTags []string // HTML tags to clean from the input
}
Config describes the way that HTMLdiff works.
