go-webkit's Introduction

go-webkit

WHATS:

Go bindings for WebKit

SCREENSHOT:

INSTALL:

To experiment with go-webkit, you can just compile and run the example program:

go run example/webview.go

LICENSE:

The library is available under the same terms and conditions as the Go, the BSD style license, and the LGPL (Lesser GNU Public License). The idea is that if you can use Go (and Gtk, or WebKit) in a project, you should also be able to use go-gtk or go-webkit.

AUTHORS:

Yasuhiro Matsumoto

GOAL:

Hopefully support following widgets and methods enough to run general application.

Newer versions of webkit

Is there any way I can use a newer version of webkit?

Submodule `docs` refers to a commit that does not exist

The docs submodule refers to a commit that does not exist. Running go get github.com/mattn/go-webkit/webkit gives this error:

Webview example doesn't open

As given in the readme I ran go run examples/webview.go. It compiles correctly.... But during runtime it throws error : Vector smash protection is enabled.
Here is the total error

Vector smash protection is enabled.

Example Crashes when Trying to Load Webpage

This is mostly an FYI. When I try to navigate to google's website, the application crashes.
I cannot run the example on Ubuntu 11.04.

cannot link go-gtk after it compiles with 6g

My machine is an Imac with OSX 10.6. When I try to use 6l demo.6 I get an error that says "too many loads". Is this a problem with Go-gtk or the go linker?

Strange error on OS X

When I try to run example on OS X I get this strange error

# command-line-arguments
HEADR too small: 4184 > 4096

Has anyone managed to get it to work on OS X?

Example crashes while loading golang.org and some other pages

I just tried to run the example. While loading the default url http://golang.org it crashes with the following trace pasted bellow. A quick change of the uri will give me the chance to browse, though there are a lot of pages which lead to such a crash. The same happens if I try to load a string.

...$ ./example

JS or document access ?

Hi,
At first, great job ! I tried a lot go-webkit and it works like a charm.

I'm currently working on a project that uses webkit in my application. I'm seeking solutions to link javascript and go application (events ? getting element and read values ?) and I don't find how to do.

Is there any way to do that job ?

Thanks a lot

Minimal example crashes with Go 1

package main

import (
    "github.com/mattn/go-gtk/gtk"
    "github.com/mattn/go-webkit/webkit"
    )

func main() {
    gtk.Init(nil)
    println("Before crash")
    wv := webkit.WebView()
    _ = wv
    gtk.Main()
}

Crashes with Go1. Amd64 Ubuntu 12.04.

More Libsoup

Hi.
Ii got an implementation made in C with webkit and made a hevy use of LibSoup inside of it (connecting to the events) your GObject interfere got an Conecct method but im puzzled on how to get the content I normally get with the C api, I mean something like thins:

g_signal_connect(Work->MainSoup,"request-queued",G_CALLBACK(callback_request_enviado),Work);

Then I define my callback
static void callback_request_enviado(SoupSession *session,SoupMessage *msg,gpointer user_data);

in that session and message i want to get more info but looks like this implementation lacks of more LibSoup binds.And Im new in Go and this is the first thing im looking that uses CGo, so its very hard for me.

Any advice will be helpful.
