Re: [Pharo-users] Code completion in Pharo?

Try Cmd-q or Ctrl-q ( and right alt click on Windows).

Spotter also has suffixes like #im #cl #sen to be put after a few
keystrokes.

Spotter: shift-enter (who knows).

Re: [Pharo-users] Code completion in Pharo?

[Tim Mackinnon]

That’s exactly the exploratory attitude we like to see...

I think the code completer is pluggable and can be selected in the settings (I 
think there are 2, and their history is probably in this list somewhere), so  
you can try your own too.

[Andrzej Olszak]

Hi Tim and Nicole,

Thanks for great tips. The click+keyModifier actions are extremely useful,
and combined with breakpoints make for a great way of 'peeking under the
hood' of the existing features.

Also, I've just found a perfect piece of real code to do some learning and
experimenting on - it will be the code completion itself! ;-)

Re: [Pharo-users] Code completion in Pharo?

[Nicole de Graaf]

Hi Andrzej,

my way of doing it:

Searching in the image what other guys are doing.

Finder: asMorph 

and here you can find methods like

#openAsMorph .. you can get a clue.

or:

‘some text’ asMorph inspect .. 
than you get the object and you can search the class and from here the class 
the references.

All my steps are based on code reading not code completion.

Code completion I use more if I know what is should be and use the same method 
names as the other developers.

Nic

Re: [Pharo-users] Code completion in Pharo?

[Tim Mackinnon]

Hi - I’m slightly ahead of you on that journey - but what I do is press 
shift-enter which gives you a great tool called spotter that lets you explore 
more interactively.  In spotter if you also press cmd-p it will also preview 
method source too - so it’s close to what you are asking (and many methods have 
docs on their first line). However - selecting a method in spitter will also 
show you other senders of that method - some of those being test cases, which 
really give you insight into how to do most things. In fact this is a powerful 
element of Pharo that is often overlooked - as it’s written in itself, and all 
the source is there, there are excellent examples of how to do real things - 
even how the compiler and browsers work.

I mention the latter, as it occurs to me that in the code completion list, it 
would be nice to press shift-enter on the method you are contemplating and be 
able to spot on it (or maybe even the whole autocompletion list) - I think this 
would actually be quite doable (armed with a bit of system knowledge of 
course). This was something I missed when I first came across Smalltalk - I was 
frustrated it didn’t do X (that my pascal environment did at the time ), not 
realising that it was simply 3 lines of code I could easily add to the  
environment myself (and nowhere near as complicated or painful as writing 
plugins for eclipse or IntelliJ).

While at it - another nice trick, is to ctrl -shift click on any item in the 
environment and you get a little graphical halo appear - of which one icon is 
debug, which then let’s you inspect the code of that item (perhaps a button - 
which inevitably has an owner or a callback method you can then jump to and see 
the source of, and thus figure out how it works). It’s all very magical and 
dare I say fun... and this is why we love Smalltalk and Pharo , they are so 
malleable.
