Problems in Introspection while developing app in javascript

[Mohan R <mohan43u gmail com>]

Hi,

I'm developing a twitter library and an app for a while.

https://github.com/mohan43u/gtweet/

I'm facing following issues which I'm not able to solve.

1. g_simple_async_result_get_op_res_gpointer() was not introspectable
which prevented me to effectively write a async function. Take a look at
gtweet_generic_callback() function at line 1083,

https://github.com/mohan43u/gtweet/blob/master/lib/tweet-object.c

Instread of setting "stream_response" property, I should have used
g_simple_async_result_set_op_res_gpointer() and should have used
g_simple_async_result_get_op_res_gpointer() to take the chunk of data
coming from twitter in GAsyncReadyCallback (through javascript). But
because of introspection, I have to introduce "stream_response" property
to workaround.

2. Gtk.CssProvider.load_from_data() and Gtk.CssProvider.load_from_path()
not working. Here is an example script,

3. GLib.Thread.new() not introspectable. If I have thread support, I can
make the twitter app much more useful by adding streaming functionality.
I believe, there is thread support in gjs. But, I'm not able to find one
example.

The twitter app(exec/twitterclientgtk.js) is working now. But, I feel
without realtime updates, there is no benefit for yet another twitter
client. I can't do it without threads. Need some help to implement
threading through javascript.

I feel current code examples in developers.gnome.org is missing lot of
informantion to write gtk app in javascript, few thing I fould,

1. Information about functions inside lang.js and signals.js.
Especially, class(), bind(), connect() and emit(). Although examples are
inside gjs source tree, It will be helpful to have a proper
documentation page.

2. Information about howto get values in out parameters (like "button"
parameter in gdk_event_get_button()). No examples provided even in gjs
source. I got a hint from this thread, and figured out how to do it.

If someone is working on improving javascript documentation, I'm willing
to help. We need more javascript examples.

Thanks,
