Where to start?

Dan Rathbun

I would like to see what contains @iptemp.

It is an Sketchup::InputPoint instance object. See the API dictionary.

What debug tools and methods can I use to debug method?

Example, utilitiestool.rb
class TrackMouseTool
method onMouseMove


@iptemp.pick view, x, y

I would like to see what contains @iptemp.

Is it possible to show dialog box or pause code?

rumcajs

If I change code of the plugin, will it be refreshed automatically or must I reload the plugin and how?

Reload it manually.

load 'myfile.rb'

Though I think Jim created a utility to autoreload after changes where detected. Never used it though as I prefer the manual control.

rumcajs

OK. Works. So I tried:

@iptemp.pick view, x, y
puts @iptemp

#Sketchup::InputPoint:0xd0fe6fc

So the input point is in hexadecimal format? If I would want to read it, I would need to add method to convert to decimal, right? I tried:
puts @iptemp.hex
returns error

thomthom

No - the hex number you see there is the hexadecimal version of the object id. Ruby convention.

Refer to the API manual and you find InputPoint.position
https://developers.google.com/sketchup/docs/ourdoc/inputpoint#position

rumcajs

Ah, now it works.

puts @iptemp.position

Something I miss in the reference manual. From different languages I am used to see above every method a list of similar or related methods/links.... Is here some similar page which gives such kind of information / organized in different way? Or is this the only source?

rumcajs

What does mean $ is it global variable? I thought it is array, but now I see they use it in different way.

This:

results = inputbox prompts, values, $exStrings.GetString("Cost Estimate")

What is inputbox, does not look like method of global scope

Each class list all its methods.

$ is global variables, yes. Avoid them.

inputbox is an alias for UI.inputbox defined in sketchup.rb which comes with SketchUp. (I use UI.inputbox simply because of potential problems of relying on the methods in the global namespace.)

rumcajs

Hm. I see. Sketchup.rb is short, so it will not be problem to remember it. And where is definited UI?

That's from the API - defined in C++.
Look to the documentation: https://developers.google.com/sketchup/docs/ourdoc/ui
