how to draw in browser?

[xf wang]

 it's easy to print words in browser,

will it easy to draw in browser in the future(or something  like java applet)?

[xf wang]

drawing in browser is OS independent?

[xf wang]

could golang use html5 api to draw? 

just like c++ use opengl api to draw?

[xf wang]

i mean,

java has jvm,

 

what about golang use browser as golang virtual machine?

[xf wang]

 what about golang use browser as golang  "canvas" virtual machine?

Perhaps you are referring to NaCL: http://code.google.com/p/nativeclient/
Go has a NaCL (Native Client) compiler. Just rebuild your Go toolchain
with 'nacl' as the target.

Just wonder, do you twitter email? Why cannot pondering a while?

A short answer is No.
html5 and browser only knows Javascript, nothing else, which I think
is good for unification (书同文).

A long answer is Yes.
Look at Svgo for one example. If that interest you, you can go on
building a local server with websocket, runs your HTML5 UI in Chrome
with realtime JSON talks. All could be done easily with Go and JS. You
would be amazed how powerful it could be.

Along the lines of your recommendation, a little bit of code I threw together a while ago:

http://pastie.org/1217341

It generates javascript canvas calls, and sends them to the browser.

(Starts up at http://localhost:12345/demo)

I don't advise this approach for anything real, but it's fun to tinker with.

 that's very nice!

how to accept mouse click?

Here's a pointer to SVGo, the library for SVG generation:

Example output (viewable in a modern browsers)

Also note that SVGo can also be used within a web server (see
websvg.go in the distribution)

[xf wang]

 wow! svgo is more like a java applet!

[xf wang]

i'm trying to test it

after 

8g -o svg.8 svg.go

gopack grc svg.a svg.8

8g -o android.8 android.go

8l -o android.exe android.8

and then how to run it under windows?

[xf wang]

btw,

i tried to 

android.exe > android.html

and it seems android.html got the code,

but  when run android.html, nothing showed in browser( in ie6 and chrome)

xf wang, please stop sending so many emails with fragmented content.
For this kind of messasging you can use other media, such as IRC or
Twitter. Thousands of people are following this list and so many
messages with so little content just wastes all their time.

I haven't run the android example. But it being part of the svgo
library, I suspect that its output is an SVG file (check it!) and thus
file should be named android.svg.

Note that generating the SVG in Go on the server does not mean that Go
is running in the client's browser. SVG files can, IIRC, be made
interactive by embedding JavaScript in them. I'm sure that a Google
search will turn up fruitful.
