Hi Marcel,


With ShoutCore-mt.76, we don't call #initializeVariablesFromContext at all if the context is dead. This means that any temporary variable or argument will be styled as an invalid identifier.

With ShoutCore-ct.76, in the same case, we call #initializeVariablesFromContext indeed and parse the whole method source. This allows us to style tempvars and args that are visible in the whole method correctly.


Maybe this visualization helps:

Best,

Christoph

Hi Christoph,

I don't know. What would be the benefit of moving the #isDead-check to #initializeVariablesFromContext? There are no useful information left for the styler or are there?

Best,
Marcel

Hi Marcel,


yes, I read your comment and liked your explanation :) Thanks for your tips!

I actually implemented this by trial & error, so I was not aware of the actual reason how it works before.


Same question as a few minutes ago: Would you like me to commit again or would this be unnecessary noise? :)


Best,

Christoph

Hi Christoph,

sounds good. Maybe a small comment on your comment from a previous contribution:

"little white lie to work in every situation"

That's a bad comment. :-) Instead of explaining "true" with "to make it always work", you should try elaborate on the meaining of "true" in this situation. I know that the interface #rangeForPC... is not perfect. However, a comment could state the relationship to the PC argument as specified above. This is what I tried to achieve with:

"to really use the context's pc"

Maybe this helps for writing comments in the future. :-)

Best,
Marcel

Hi Marcel,


Did you see ShoutCore-ct.76? I think my solution could also work for dead contexts, instead of just refusing to style :-)


Best,

Christoph
