feature request - upgrading and proper signing

This request follows on from the PKG bundling request.

With the package properly signed using the OSX toolset, it means we can do upgrades that are secure and tamper proof that check the signing.

There are many golang updaters out there that have various features btw, but this one looks good:
https://github.com/syncthing/syncthing/tree/master/lib/upgrade

Checks signatures
Battle Tested (handles allot of corner cases)
Manages version checking.
Tests

Also check this:
https://github.com/syncthing/syncthing/blob/master/build.go
Its a nice way to do it. The golang team does the same with a root build.go.

Lastly between the bundling and the upgrading we need to upload the bundle somewhere:
https://github.com/golang/build/blob/master/cmd/release/upload.go

I think that this makes it very easy to bundle and deploy and because its all golang based easy to fix and cross platform.

Curious what you think and any things you want changed etc ?

waiting for windows support good job

Build a `gallium` tool to build and bundle projects

The project has a couple of important requirements:

Running runtime.LockOSThread and gallium.Loop on the main function
Bundling the binary for certain features to work. e.g: the menu example only works when run from a bundle.

Instead of having people create their own main files, it might be helpful to have a CLI to manage both compilation and bundling.

The UX would be something like this:

`github.com/alexflint/gallium/examples/menu/menu.go`

package menu

import (
    "os"

    "github.com/alexflint/gallium"
)

type app struct {}

func New() gallium.Starter {
    return &app{}
}

func (*app) Start(app *gallium.App) {
    app.SetMenu([]gallium.Menu{
        {
            Title: "menudemo",
            Entries: []gallium.MenuEntry{
                gallium.MenuItem{
                    Title:    "Quit",
                    Shortcut: "cmd+q",
                    OnClick:  func() { os.Exit(0) },
                },
            },
        }
    })
}

Building the application

$ gallium build github.com/alexflint/gallium/examples/menu

As part of the build, it will create a temporary main package with a main.go file from a template similar to this:

// AUTOGENERATED CODE
// NEVER EDIT MANUALLY
package main

import (
    "runtime"

    "github.com/alexflint/gallium"
    p "{{ .TargetPackage }}"
)

func main() {
    runtime.LockOSThread()
    app := p.New()
    gallium.Loop(os.Args, app.Start())
}

Once generated, it will build the binary and bundle it and produce a ready menu.app.

Beyond not having to deal with thread locking and initialising the loop, we can check whether the returned satisfies other gallium interfaces to build more elaborate main files.

DefaultMenus() []gallium.Menu returning the default menu for the app
Config() gallium.Config could return information used to setup your app or your bundle. Would probably have some information like the one contained in cordova's (phonegap) config.xml.

The CLI could also evolve to offer other features:

$ gallium new           # creates a default app ready to be used with `gallium build`
$ gallium generate menu # generates all the boilerplate to return a new menu
$ gallium sign Menu.app # signs Menu.app for distribution

It should also have a command to generate all the Go code needed to build and bundle the app with within the same repo. Everything that would be required to build the app without the cli, so it can be committed to the repo.

add support for Linux

Securing http requests from gallium

There will be different security requirements for the HTTP connections from libchromiumcontent.

Restricting what domains/URLs libchromiumcontent has access to.
Starting an HTTP server embedded in the app that only libchromiumcontent has access to.
Preventing sniffing of the traffic between libchromiumcontent and the embedded server.

@alexflint, I have some ideas about how to address this, I can create issues for each of these points and outline some proposals if you want.

Screen Capture

Hello, I was wondering if you can point me in the right direction to implement something like the following http://electron.atom.io/docs/api/web-view-tag/#webviewcapturepagerect-callback. I'm not sure how gallium exposes any chromium functionality. I'd love to help but sadly I don't quite know where to start.

example/controller: after "Miniaturize" & restore, screen is blank

just hit a bug In examples/controller.

steps to reproduce:

press "Miniaturize"
maximise / restore it again and you will see the white web page is 100% white.

Menus don't show up unless you run the application bundle

It's not very clear from the instructions in the README:

To run the example as a full-fledged UI application, you need to build an app bundle:
...
Alternatively, you can run the executable directly, but the window will initially appear behind all other windows, and it will also not appear in the dock or the switcher, so you will have to find it manually:

Can you add a note in the "common pitfalls" that explains that ? It took me a while to figure out why everything was working but the menus.

what time will support windows?

Question : Can be used headless?

I am wondering if this can work headless if yes any documentation available?

Roadmap

This project has 2000 stars. This is really useful and fils a need in the community I believe.

How you you feel about a roadmap ? People can contribute cross platform stuff then

I used Cordova and electron and scorer and want to support this project. Windows support is important to me and maybe others

Form and inputs

What are the plans for forms? It seems like a crucial component for any app.

Build MSI for Windows

i know we are not doing windows yet, but this golang based way to build an MSI is very well done

https://github.com/mh-cbon/go-msi/blob/master/appveyor-recipe.md

so parking here for now :)

MacOS Termination Reason: DYLD, [0x1] Library missing

Hi guys,

embedded Chromium with Gallium is working great so far on the development machine but as soon as I run the app bundle on a different Mac it can't find the library.
Am I missing some build or bundle parameter here?

This is how I did the build:

go build -o example main.go
gallium-bundle example

Took the example.app and tried it on a different Mac.

Error:

...

Trouble installing: "could not determine kind of name for C.CBytes"

I'm new to go, so might be an obvious package missing on my end, but can't figure out what.

what is the status of this project? dead or live?

browser shortcuts and keybinding events are not working properly

The navigation keyboard shortcuts found in Chome (i.e. cmd + arrow left/right to navigate back or forward) are not working.
Listening to keyboard events (using javascript) is not working either(i.e. I've registered a listener on a specific key press to launch the video element in fullscreen but it doesn't work either).

Breach and Thrust??

This is more of a polite enquiry than anything else!!!

Are you aware of the Breach browser project and in particular its second iteration of its core Thrust. It is an abandoned polyglot version of electron like application framework based on chromium content module which I had some hopes for!

The reason I am asking you about this is because it may help hasten a windows and linux version of gallium ...

Mac only?

The Mac only requirement is not made clear in the README.
What do you think about adding something to say this will only work on Mac?

Form text inputs not responding in go run

Not sure if this is mentioned somewhere or not but I am unable to enter text into a form input box. Whatever I type is redirected to the console where I ran go run. I ran build and the form was then usable. Is there something I missed?

Add more video codecs to chromium layer

how could one add more codecs? for example by default chromium supports matroska, mp4 and so on, i would like to support avi/wmv

Name collision with "Gallium"

Gallium is a low-level set of platform graphics driver libraries, and is used on multiple operating systems to allow implementing interfaces for graphics APIs (DirectX, OpenGL, Vulkan) on top of different drivers.

https://en.wikipedia.org/wiki/Gallium3D

This causes also the issue that the "gallium" package name in most linux distros is already used, so this project would have to be called something different there.

Is gallium not being actively worked on - as of 2017

Hey @alexflint

First off, I think this is an awesome project!!

I'd really love to see this one continue, checked out the Activity graph for this project and the dev seems to be slowing down. Could you please let me know what are your plans for gallium's future?

Platform in background?

Use electron under or go native?

feature request - bundle as a .pkg

i noticed the recent work on the bundling at https://github.com/alexflint/gallium/blob/master/cmd/gallium-bundle/bundle.go

looking awesome !

At the moment the bundling produces a ".app", however its possible with golang to produce a ".pkg" so that the end user gets a decent install experience, and we are developers get control about where things are places and file ACLS assigned etc.
It will also help with getting projects into a CI and CB pipeline, and prepare for continuous updates if we want to integrate that later.

This is the way the golang team does it and its quite simple.
https://github.com/golang/build/blob/master/cmd/release/releaselet.go#L149

It will only build on OSX.
it calls out to pkgbuild & then productbuild for final signing for users.
Its described well here:
http://thegreyblog.blogspot.de/2014/06/os-x-creating-packages-from-command_2.html
I think its very complete.

Please let me know what you think....

Frameless windows cannot accept keyboard input

If you construct a window using gallium.FramelessWindow then you will not be able to type into form elements on the page, or provide any other kind of keyboard input. This is because Cocoa defaults canBecomeKeyWindow to false for borderless windows. The suggested fix is to override canBecomeKeyWindow and return true. This will require subclassing OpenGLUnderlayWindow.

LSOpenURLsWithRole() failed with error -10810

Hi, I'm just trying to run the Quickstart example but I'm facing some issues.

I have installed Gallium following the step-by-step from the Installation section in the README file.

Now, I'm trying to create a new Go project following these steps:

On the Go workspace:

$ mkdir example
$ cd example
$ touch example.go
$ open example.go

I copied the following code to the example.go file:

package main

import (
  "os"
  "runtime"

  "github.com/alexflint/gallium"
)

func main() {
  runtime.LockOSThread()         // must be the first statement in main - see below
  gallium.Loop(os.Args, onReady) // must be called from main function
}

func onReady(app *gallium.App) {
  app.OpenWindow("http://example.com/", gallium.FramedWindow)
}

Then I ran the following commands:

$ go build
$ go install github.com/alexflint/gallium/cmd/gallium-bundle
$ gallium-bundle example
$ open example.app

And I got the following error message:

LSOpenURLsWithRole() failed with error -10810 for the file /Users/username/Developer/GoWorkspace/src/github.com/username/example/example.app.

Also when I try to run the go run example.go command I get it signal: killed.

I don't know if it is a Gallium issue or if I'm doing something wrong, but I couldn't figure out what is happening. If someone can help me I will appreciate.

I'm running it on MacOS Sierra Version 10.12.5 using Go version 1.8.

By the way, congratulations for the great project.

How does one build gallium from libchromiumcontent

I would like to know where the gallium library is built from libchromiumcontent. Do you have a separate repository for this?

Please add a license to the repo

Hi @alexflint,

Could you please add an explicit LICENSE file to the repo so that it's clear under what terms the content is provided, and under what terms user contributions are licensed?

Per GitHub docs on licensing:

Generally speaking, the absence of a license means that the default copyright laws apply. This means that you retain all rights to your source code and that nobody else may reproduce, distribute, or create derivative works from your work. This might not be what you intend.

In case it's helpful, choosealicense.com provides a nice overview of several popular open source licenses from which to choose.

Thanks!
