[ANN] MessageFlowBrowser

A new tool to browse and dive deep into the flow of messages
using a tree representation (messages, senders, implementors, ...)
and further on. I know such a tool from Smalltalk/MT and it is really
helpful to trace a message flow without running in the debugger.

See the attached screenshot, the best is to try it:

In a latest Pharo 5.0 image (Pharo5.0 Latest update: #50314)
you can evaluate:

Gofer new
url: 'http://smalltalkhub.com/mc/TorstenBergmann/MessageFlowBrowser/main';
package: 'Tool-MessageFlowBrowser';
load

to load it.

Then open whatever method in Nautilus and choose "Message Flow" from the context
menu. The nice thing is that you can dive into senders, implementors, messages sent
deeper and deeper (or up again) and you do not open more and more windows but stay
in a single window !!!

Alternatively you can start the tool from the playground:

MessageFlowBrowser openOn: #inspect "open the flow browser on a selector"

MessageFlowBrowser openOn: (Compiler>>#evaluate) "open the flow browser on a method"

MessageFlowBrowser openOn: Object "open the flow browser on a class"

1 messageFlow. "open the flow browser on the class of an instance"

If someone with GT knowledge and time could help to correct the syntax highlighting
in the code pane this would be super cool (see method MessageFlowBrowser #openOn:).
Also selection could be improved to show/highlight the messages sent directly
in the code. Unfortunately I'm not so familar with the current code editors - so
any help is appreciated.

Repo is open for contribution.

Thanks
T.

Great!

You need to set the class this method belongs to:

a smalltalkCode
   smalltalkClass: [:each | each <class/behavior> ];
   display: [:each | each sourceCode ]].

Yes - I know that. At least from the code I found in the image.
But how do I do that in the context of Glamour where the tree is
transmitted to the code pane...

See #openOn: in MessageFlowBrowser.

Hi Torsten,

Can you make it available from the catalog browser ?

Also, it would be great to have it accessible from the World/Tools menu.

Coooool
I want to try it!
Thanks for it. This was a project I wanted to propose.

Some new changes:

- Catalog methods were added and config is in MetaRepoForPharo50
=> should be available in CatalogBrowser and Spotter by tomorrow after catalog job run

- it is now possible to browse the methods

- class comment added

- syntax highlighting is now working correctly (was easier than I thought - should always remember GT methods also accept blocks!)

Is there any code that marks/selects messages in a smalltalkCode editor?

Would be cool if you browse the messages that a method sends and you

click on the displaed method selectors in the tree they will be highlighted

in the code pane...

No as it is not a standalone tool. You need to have a method or selector first

to display some contents. When catalog job is ready and catches the new

ConfigurationOfMessageFlowBrowser (tomorrow) you can:

- hit ALT+ENTER to open spotter

- search for the project by entering "Flow" and load it

- when it is loaded just use "Method Flow" on a method in Nautilus

Maybe it would be good to have something similar to Cmd+M shortcut

that works on selected text and that is interpretet as selector.

If you feel something is missing: the repo is open. An improved version

could possibly be a part of Pharo 5. A nice extension would be to add

also "local senders" and "local implementors" to it (= local to the class and

up the hierarchy)

Have fun

not there yet… I suppose we need to wait the refresh :)

yes, this was a missing tool.

we could discuss also it’s introduction in the core distribution… what do you think?
