GitHub - aymerick/douceur: A simple CSS parser and inliner in Go (original) (raw)
douceur 
A simple CSS parser and inliner in Golang.
Parser is vaguely inspired by CSS Syntax Module Level 3 and corresponding JS parser.
Inliner only parses CSS defined in HTML document, it DOES NOT fetch external stylesheets (for now).
Inliner inserts additional attributes when possible, for example:
Inline me !
`Becomes:
Inline me !
`The bgcolor attribute is inserted, in addition to the inlined background-color style.
Tool usage
Install tool:
$ go install github.com/aymerick/douceur
Parse a CSS file and display result:
$ douceur parse inputfile.css
Inline CSS in an HTML document and display result:
$ douceur inline inputfile.html
Library usage
Fetch package:
$ go get github.com/aymerick/douceur
Parse CSS
package main
import ( "fmt"
"github.com/aymerick/douceur/parser")
func main() { input := `body { /* D4rK s1T3 */ background-color: black; }
p { /* Try to read that ! HAHA! / color: red; / L O L */ } `
stylesheet, err := parser.Parse(input)
if err != nil {
panic("Please fill a bug :)")
}
fmt.Print(stylesheet.String())}
Displays:
body { background-color: black; } p { color: red; }
Inline HTML
package main
import ( "fmt"
"github.com/aymerick/douceur/inliner")
func main() { input := `
Inline me please!
`html, err := inliner.Inline(input)
if err != nil {
panic("Please fill a bug :)")
}
fmt.Print(html)}
Displays:
Inline me please!
