Re: [ANN] AbsTK – a widget toolkit for GUI and TUI applications

[Dr Eberhard Lisse <nospam@...>]

Thanks everybody,

but the fascination of this is that it can do curses AND gtk.

I have gtk+3 and gobject-introspection installed from Homebrew as they
are dependencies for stuff like gnumeric. I also had gtk+

I have noew removed gtk+ and reinstalled gtk+3, gobject-introspection
(through homebrew) and abstk (through luarocks).

libgirepository1.0-dev sounds like an APT package (ie ubuntu). Can't
find it in homebrew.

When running the example (t.lua)

local abstk = require 'abstk'
abstk.set_mode(...)
local scr = abstk.new_screen("My First AbsTK UI")
scr:add_label('hellow', "Hello, World!")
scr:add_label('msg1', "This is a minimal example to demonstrate AbsTK.")
scr:add_label('msg2', "The Screen is the main object of the toolkit. It
can run as standalone or added to a Wizard. Its routine consists in
creating it (line 2), populating it (lines 3 to 7) and running it (line
8).")
scr:run()


I get something like

lua t.lua gtk
lua: /usr/local/share/lua/5.2/abstk.lua:61: attempt to index upvalue
'AbsGtk' (a nil value)
stack traceback:
	/usr/local/share/lua/5.2/abstk.lua:61: in function 'new_screen'
	t.lua:5: in main chunk
	[C]: in ?
	
when I do this

lua t.lua curses

nothing seems to happen, but when I scoll back on the scrren I get the
blue window epected and this:

/usr/local/bin/lua: /usr/local/share/lua/5.2/abstk/AbsCurses.lua:200:
attempt to index upvalue 'utf8' (a nil value)
stack traceback:
         /usr/local/share/lua/5.2/abstk/AbsCurses.lua:200: in function 'new'
         /usr/local/share/lua/5.2/abstk/AbsCurses.lua:947: in function
'create_widget' /usr/local/share/lua/5.2/abstk/AbsCurses.lua:955: in
function 'add_label'
        /usr/local/share/lua/5.2/abstk.lua:77: in function 'add_label'
        ./t.lua:6: in main chunk
        [C]: in ?


Anyone using homebrew out there?
