Package syntaxhighlight provides syntax highlighting for code. It currently uses a language-independent lexer and performs decently on JavaScript, Java, Ruby, Python, Go, and C.
The main AsHTML(src []byte) ([]byte, error) function outputs HTML that uses the same CSS classes as google-code-prettify, so any stylesheets for that should also work with this package.
go get github.com/sourcegraph/syntaxhighlight
The function AsHTML(src []byte) ([]byte, error)
returns an HTML-highlighted version of src. The input source code can be in
any language; the lexer is language independent.
package syntaxhighlight_test
import (
"fmt"
"os"
"github.com/sourcegraph/syntaxhighlight"
)
func Example() {
src := []byte(`
/* hello, world! */
var a = 3;
// b is a cool function
function b() {
return 7;
}`)
highlighted, err := syntaxhighlight.AsHTML(src)
if err != nil {
fmt.Println(err)
os.Exit(1)
}
fmt.Println(string(highlighted))
// Output:
// <span class="com">/* hello, world! */</span>
// <span class="kwd">var</span> <span class="pln">a</span> <span class="pun">=</span> <span class="dec">3</span><span class="pun">;</span>
//
// <span class="com">// b is a cool function</span>
// <span class="kwd">function</span> <span class="pln">b</span><span class="pun">(</span><span class="pun">)</span> <span class="pun">{</span>
// <span class="kwd">return</span> <span class="dec">7</span><span class="pun">;</span>
// <span class="pun">}</span>
